Osteochondroses of the foot represent a unique and less frequently discussed topic. This narrative review aims to provide a comprehensive overview of foot osteochondroses, highlighting their definition, pathophysiology, clinical features, diagnosis, and treatment. Historical sources, including early case reports, were included along with the current literature to picture the current knowledge on the subject. Anatomical mapping of pain locations and associated ossification centers was employed as a framework to present the various forms of foot osteochondroses. Multiple types of foot osteochondrosis were identified. The calcaneus, navicular and lesser metatarsal are among the more common involved bones. Most forms share a multifactorial etiology involving mechanical stress, vascular insufficiency, and delayed ossification. The pain is localized and common to all forms. Diagnosis relies on clinical assessment supported by radiographic and sometimes magnetic resonance imaging findings. During the acute phase, joint rest is essential. Despite the potential for spontaneous resolution, some cases can lead to structural deformities or persistent symptoms. Foot osteochondroses, although rare, require careful clinical evaluation due to their impact on pediatric patients. Increased awareness and standardized treatment approaches may improve early recognition and management, potentially reducing long-term sequelae. Full article

Background/Objectives: Avascular necrosis of the femoral head is a debilitating condition that, if left untreated, leads to progressive arthritis necessitating total hip replacement (THR). In the younger adult population, there is a drive towards joint-preserving procedures, particularly where alternative techniques such as core decompression or vascularised bone grafting are anticipated to fail. Proximal femoral osteotomy is a technique that aims to remove the necrotic segment from the weight bearing area. The presented review aims to examine the efficacy of this technique in the management of avascular necrosis of the femoral head, reporting both rates of conversion to total hip replacement and patient reported outcomes. Methods: This systematic review was conducted according to PRISMA guidelines. A search was conducted of PubMed, Ovid Medline, EMBASE, and the Cochrane Library using pre-defined search terms. Data were extracted, and descriptive data presented. Quality of each study was assessed using the NIH quality assessment tool for case series studies. Results: Fifty-three studies with data for 2686 osteotomies are presented. Progression of radiological arthrosis was present in 40% of cases, with 20.3% of patients having undergone conversion to THR at a mean of 75.4 months (range 20–132 months). Patient-reported outcome measures were recorded in 1416 patients, of which the Harris Hip Score was the most commonly utilised. This score improved from a mean of 58.3 to 84.4 at a mean follow-up of 102 months. Conclusions: Osteotomy represented a valid head-preserving technique in the armamentarium against avascular necrosis of the femoral head, with conversion to THR required in 20.3% of patients at 7 years. In those patients who did not require THR, PROMS were similar to the arthroplasty population. Full article

Background/Objectives: The most common limb-salvage procedure for end-stage ankle arthropathy with severe bone defect is arthrodesis. Successful fusion requires rigid metal fixation, effective filling of the bone defect space, and maximal securing of the contact area between the tibia and talus. In cases with severe bone defect, sufficient grafting using autogenous bone alone is limited, and there is still controversy regarding the effectiveness of allogeneic or xenogeneic bone grafting. This study aimed to evaluate the intermediate-term clinical outcomes after shortening arthrodesis using fibular osteotomy for ankle arthropathy with severe bone defect. Methods: Twenty-two patients with shortening ankle arthrodesis were followed up ≥ 3 years. All operations were performed by one senior surgeon and consisted of internal fixation with anterior fusion plate, fibular osteotomy, and autogenous bone grafting. The causes of ankle joint destruction were failed total ankle arthroplasty (7 cases), neglected ankle fracture (6 cases), delayed diagnosis of degenerative arthritis (5 cases), avascular necrosis of talus (2 cases), and diabetic neuroarthropathy (2 cases). Clinical outcomes including daily living and sport activities were evaluated with the Foot and Ankle Outcome Score (FAOS) and the Foot and Ankle Ability Measure (FAAM). Radiological evaluation included fusion rate, time to fusion, leg length discrepancy, and degenerative change in adjacent joints. Results: The FAOS and FAAM scores significantly improved from a mean of 21.8 and 23.5 points preoperatively to 82.2 and 83.4 points at final follow-up, respectively (p < 0.001). Visual analogue scale for pain during walking significantly improved from a mean of 7.7 points preoperatively to 1.4 points at final follow-up (p < 0.001). The average time to complete fusion was 16.2 weeks, and was achieved in all patients. The average difference in leg length compared to the contralateral side was 11.5 mm based on physical examination, and 13.8 mm based on radiological examination. During the average follow-up of 56.2 months, no additional surgery was required due to progression of degenerative arthritis in the adjacent joints, and no cases required the use of height-increasing insoles in daily life. Conclusions: Shortening ankle arthrodesis using fibular osteotomy and anterior fusion plate demonstrated satisfactory intermediate-term clinical outcomes and excellent fusion rate. Advantages of this procedure included rigid fixation, preservation of the subtalar joint, effective filling of the bone defect space, and maximal securing of the contact area for fusion. The leg length discrepancy, which was concerned to be a main shortage, resulted in no significant clinical symptoms or discomfort in most patients. Full article

Background: Displaced proximal humerus fractures (PHFs) in adults represent a common orthopedic challenge, especially in elderly patients with compromised bone quality. Intramedullary nails (IM) and locking plates (LP) are the most widely used fixation techniques, though the literature remains inconclusive regarding their comparative efficacy. Methods: This retrospective cohort study included 187 patients (mean age: 65.4 years) treated surgically for Neer ≥ 2-part proximal humerus fractures at a single tertiary referral center between 2018 and 2023. Patients underwent either IM nailing or LP fixation. Baseline characteristics included age, sex, smoking status, ASA score, trauma mechanism, and bone quality (assessed by the Deltoid Tuberosity Index). Functional outcomes (DASH and Constant–Murley scores), range of motion (ROM), radiographic healing, and complications were evaluated at 1, 3, 6, and 12 months postoperatively. Results were stratified by fracture type (two-, three-, and four-part fractures) and treatment group. Results: At 12 months, no statistically significant differences were found between groups in terms of DASH (p = 0.484) or Constant–Murley scores (p = 0.057). ROM recovery was comparable across all time points. Stratified analysis showed similar outcomes across fracture types. Age, smoking, and bone quality did not significantly influence clinical results. The overall complication rate was 11.8%, with no significant difference between groups. Avascular necrosis and hardware-related issues occurred predominantly in four-part fractures. Conclusions: Both intramedullary nailing and locking plate fixation provided comparable short-term outcomes for displaced PHFs. Functional recovery appeared more dependent on fracture complexity than on the choice of implant. Surgical technique should therefore be selected based on fracture morphology, patient characteristics, and surgeon experience. Full article

Background: Toggling of the short cephalomedullary nail is an understudied phenomenon characterized by a change in the longitudinal axis of the nail in relation to the longitudinal axis of the femoral medullary canal, with subsequent potential loss of reduction. This retrospective study aims to examine the incidence and impact of toggling of short cephalomedullary nails in cases with wide femoral canals. Methods: One thousand two hundred fifty-six (1256) cases that received short proximal femoral nails for intertrochanteric fractures were reviewed. Of them, 101 cases that had wide femoral canals (≥15 mm) and a minimum radiographic follow-up of 6 weeks were included in this study. Outcome measures included nail toggling, varus malunion and revision surgery. Results: After a mean radiographic follow-up of 53.5 weeks, sixteen cases (15.8%) showed significant nail toggling of more than 4 degrees and had subsequent varus displacement of the fracture. In all 16 cases, there was deficient proximal nail fixation, in the form of either a lag device not engaging the lateral wall (2 cases), lateral proximal femoral wall fracture/incompetency (7 cases), or a combination of the two factors (7 cases). Despite this, all sixteen cases achieved fracture union. Five additional cases had complications related to poor initial reduction (four cases) or femoral head avascular necrosis (one case). The other 80 cases had minimal (0–4 degrees) nail toggling and healed without varus malunion, and none of them required revision surgery. Conclusions: Short cephalomedullary nails may toggle in patients with wide femoral canals. The effect of femoral canal width on nail movement and subsequent varus malunion may be abolished when the lag device engages the lateral proximal femoral cortex, and the lateral cortical bone is intact. In patients with wide femoral medullary canals or cases with proximal lateral femoral cortical fracture, the utilization of long or intermediate length cephalomedullary nails may be a more viable option.

Background: Complex hindfoot pathologies involving critical-sized bone defects of the talus are difficult to manage. The current management involves arthrodesis and bone grafting with the defective talus, which have limitations in restoring structural integrity and functional goals. The advancement of 3D-printed scaffolds has opened new avenues to address such complex hindfoot pathologies, which may potentially improve treatment outcomes. The addition of platelet-rich fibrin further enhances healing potential. Method: This is a retrospective study involving six patients with severe talar bone loss secondary to osteomyelitis or avascular necrosis, where 3D-printed scaffolds coated with PRF were implemented in salvage surgery performed from 2023 to 2024. We intended to investigate the clinical outcomes in terms of healing time and union rate. Additionally, we evaluated the degree of deformity corrections and the patients’ clinical outcomes. Results: This study reports six complex reconstructions which achieved CT-confirmed union after a mean duration of 20.2 weeks. All patients were able to ambulate with full weight bearing after an average duration of 23.3 weeks. The patients demonstrated improved radiological parameters, VAS scores from 7.5 ± 1.4 points to 2.3 ± 1.2, and functional scores in all domains for AOFAS, FFI and SF-36. Conclusion: This study demonstrates the benefits of PRF-coated 3D-printed scaffolds in managing complex hindfoot cases, especially in the presence of significant bony defects. This modality has the potential to achieve a good union rate, near-anatomical correction and good functional outcomes. Full article

Background: Tibiotalocalcaneal (TTC) arthrodesis using talar allografts has emerged as a viable surgical option for managing complex hindfoot pathologies, including post-traumatic avascular necrosis (AVN), infection-related complications, and failed total ankle replacement (TAR). These conditions present significant therapeutic challenges due to extensive bone loss and joint instability. Previous reports have focused on TTC arthrodesis using talar allografts, highlighting its potential to provide enhanced structural support. This study aims to further evaluate the efficacy and safety of this surgical approach by assessing union, clinical outcomes, and complications in a diverse patient population. Methods: This retrospective study reviewed 11 patients who underwent TTC arthrodesis with talar allograft between January 2020 and November 2022. The study cohort included patients with post-traumatic AVN, infection-related complications, and failed TAR. Preoperative and postoperative evaluations included X-rays, computed tomography scans, and functional outcome scores such as the Visual Analog Scale (VAS) and the Foot and Ankle Outcome Score (FAOS). Results: This study included 11 patients who underwent surgical treatment between January 2020 and November 2022, with a minimum follow-up of 24 months and a mean follow-up of 33.45 months (range, 24–50 months). Successful arthrodesis was observed in nine patients, yielding a success rate of 82%. Significant improvements in functional outcomes were noted, including marked reductions in pain and enhanced activity levels, as evaluated by VAS and FAOS scores. Two patients demonstrated radiographic nonunion (one tibiotalar, one subtalar), but both remained asymptomatic and did not require revision surgery. No other complications such as infection, wound issues, or thromboembolism were observed. Immediate postoperative radiographs confirmed appropriate allograft alignment and placement. Conclusions: TTC arthrodesis using structural talar allografts may be a viable and safe option for managing severe hindfoot pathology, potentially resulting in satisfactory fusion rates and clinical outcomes.

Background/Objectives: Femoral head avascular necrosis (FAN) is a serious orthopedic disorder that causes the death of bone tissue as the outcome of the occlusion or insufficiency of the vessels supplying blood to the femoral head. It is especially common in middle-aged men. Factors such as alcohol consumption, corticosteroid use, trauma, and systemic diseases have influential roles in the development of FAN, and the ensuing vascular disruptions can also negatively affect the patient’s broader systemic vascular health. Erectile dysfunction (ED) is a condition caused by an impairment in penile blood flow, which reduces quality of life in men and has psychosocial effects. This study examined the potential relationship between FAN and ED in consideration of the similar pathophysiological mechanisms of these conditions. Methods: The research was planned as a retrospective case–control study and conducted between January 2020 and December 2023. FAN was diagnosed based on the Ficat–Arlet classification using plain radiography and magnetic resonance imaging, and staging was performed with expert clinical evaluations. The International Index of Erectile Function (IIEF) scale was administered to evaluate ED. Data from 50 patients with FAN and 50 healthy men were evaluated using appropriate statistical methods, including univariate comparisons and correlation analysis. Results: The analysis demonstrated a significant association between increasing FAN stages and greater severity of erectile dysfunction (ED). ED was identified in 35 out of 50 patients in the FAN group (70%), compared to 15 out of 50 individuals in the control group (30%). This difference was statistically significant (p < 0.05), indicating a substantially higher prevalence of ED in patients with FAN. A significant negative correlation was also observed between the FAN stage and International Index of Erectile Function (IIEF) scores (Spearman’s rho = −0.631; p = 0.001). The mean IIEF score was 23.4 in patients with FAN stage 1, which declined to 9.6 in those with stage 4, reflecting a marked deterioration in erectile function with advancing FAN stages. No statistically significant difference was found in the age distribution between the FAN and control groups (p > 0.05). Conclusions: This study demonstrates that, with the progression of FAN, systemic vascular deterioration affects penile blood flow, increasing the severity of ED. This finding highlights the common pathophysiological mechanisms of FAN and ED and reveals the importance of early diagnosis and multidisciplinary treatment approaches. This relationship should be examined in detail with larger samples and prospective designs in future studies. Full article

Background/Objectives: Vascularized bone grafts have been successfully established for complex bone defects. The integration of three-dimensional (3D) simulation and printing technology may aid in more precise surgical planning and intraoperative bone shaping. The purpose of the present study was to describe the implementation and surgical application of this innovative technology for bone reconstruction. Methods: This prospective pilot study was conducted between June 2019 and June 2024. For this evaluation, patients who received vascularized bone reconstruction assisted with 3D technology were included. For reconstruction, the free medial femoral condyle (MFC) flap was used as the vascularized bone graft. Patient-specific 3D-printed templates, based on individual 3D simulations according to defect characteristics, were used for surgical planning, including flap elevation, shaping and inset. Results: A total of six patients (five male) with an average age of 39 years (range 19–62 years) and a mean follow-up time of 15 months (range 5–24 months) were analysed. The indications were as follows: avascular necrosis of the carpal bones, a metacarpal defect after tumor resection and pseudoarthrosis after a fractured ulna. Three patients received an osteochondral and three patients received a cortico-cancellous MFC flap. Conclusions: Our evaluation of clinical application revealed enhanced preoperative planning as well as intraoperative performance. Although the implementation for this technology is challenging, the new insights gained in planning and surgical guidance have led us to incorporate this technology into our standard routine.

Background: Ankle arthritis is a common degenerative disease that progresses as cartilage damage in the lower tibia and upper talus progresses, resulting in loss of joint function. In addition to typical arthritis, there is also structural bone loss in the talus due to diseases such as talar avascular necrosis. Total talus replacement surgery is the procedure of choice in end-stage ankle arthritis and consists of a tibial, talar component and an insert. However, in cases of severe cartilage and bone damage to the talar bone with less damage to the tibial cartilage, a talar component hemiarthroplasty may be considered. Although the application of total talus replacement surgery using ceramics has been studied, reports on the application of metal 3D printing technology are limited. We aimed to investigate the feasibility of partial talar components using ceramic and titanium 3D printing technology in terms of biocompatibility and stability through animal experiments. Methods: Preoperative 3D CT was acquired and converted to STL files to fabricate a partial talus component for ankle hemiarthroplasty using ceramic and titanium. Six minipigs with an average age of 17 months were implanted with three ceramic (C-group) and three titanium talar components (T-group) in the hind limb ankle joint. The surgery was performed under anesthesia in a sterile operating room and was performed by two experienced foot and ankle specialist orthopedic surgeons. Blood analysis and CT were performed before surgery and every month for 3 months after surgery to assess the extent of inflammatory response and physical stability, sacrifices were performed 3 months after surgery, and H&E staining and micro-CT analysis were performed to compare histological biocompatibility. A grading score was calculated to semi-quantitative assess and compare the two groups. Results: In the postsurgical evaluation, blood analysis revealed that both groups had increased white blood cell counts on the postoperative day after surgery. The white blood cell count increased more in the titanium group (1.85-fold) than in the ceramic group (1.45-fold). After 3 months, all values normalized. During the study, CT analysis confirmed that all artificial samples were displaced from their initial positions. In micro-CT analysis, the adhesive tissue score of the ceramic artificial sample was better than that of the titanium sample (average threshold = 3027.18 ± 405.92). In histologic and grading scores for the inflammatory reactions, the average inflammation indices of the ceramic and titanium groups were 2.0 and 1.21, respectively. Also, the average grade score confirmed based on the results of fibrous tissue proliferation and new blood vessels was 18.4 in the ceramic application group and 12.3 in the titanium application group. Conclusions: In conclusion, both titanium and ceramics have excellent biocompatibility for artificial joints, and ceramic materials can be used as novel artificial joints. Further research on the strength and availability of these ceramics is required. Full article

Bone metastasis and steroids are known to activate the coagulation system and induce osteoporosis, pathological bone fractures, and bone pain. Heparanase is a protein known to enhance the hemostatic system and to promote angiogenesis, metastasis, and inflammation. The objective of the present study was to evaluate the effects of steroids and malignancy on the coagulation factors and osteoblast activity in the bone tissue. The effects of dexacort and malignant medium were evaluated in osteoblasts derived from human bone marrow mesenchymal stem cells and human umbilical vein endothelial cells (HUVECs). The bones of mice treated with dexacort for 1 month were studied. Bone biopsies of ten patients with bone metastasis, ten with steroid-induced avascular necrosis (AVN), and ten with osteoarthritis were compared to ten controls. We found that dexacort and malignant medium significantly increased the heparanase levels in osteoblasts and HUVECs and decreased the levels of alkaline phosphatase (ALKP). Peptide 16AC, derived from heparanase, which interacts with tissue factor (TF), further increased the effect, while peptide 6, which inhibits interactions between heparanase and TF, reversed the effect in these cells. The bone microcirculation of mice treated with dexacort exhibited significantly higher levels of heparanase, TF, TF pathway inhibitor (TFPI), TFPI-2, thrombin, and syndecan-1, but reduced levels of osteocalcin and ALKP. The pathological human bone biopsies’ microcirculation exhibited significantly dilated blood vessels and higher levels of heparanase, TF, TFPI, TFPI-2, and fibrin. In summary, steroids and malignancy increased the activation of the coagulation system in the bone microcirculation and reduced the osteoblast activity. Heparanase inhibitors should be further investigated to attenuate bone fractures and pain. Full article

Talar avascular necrosis (AVN) is a devastating condition that frequently follows type III and IV talar neck fractures. As 60% of the talus is covered by hyaline cartilage, its vascular supply is limited and prone to trauma, which may eventually lead to AVN development. Early detection of AVN (Hawkins sign, MRI) is crucial, as it may prevent the development of the irreversible stages III and IV of AVN. Alertness is advised regarding non-obvious conditions that may cause this complication (sub chondroplasty, systemic lupus erythematosus, diabetes mellitus). Although, in stages I–II, AVN may be treated with non-surgical procedures (ESWT therapy, non-weight bearing) or joint-sparing techniques (core drilling, bone marrow aspirate injections), stages III–IV require more advanced procedures, such as joint-sacrificing procedures (hindfoot arthrodesis/ankle arthrodesis), or replacement surgery, including total talar replacement (TTR) or combined total ankle replacement (TAR). The advancement of 3D-printing technology and increased access to implant manufacturing are contributing to a rise in the production rates of third-generation total talar prostheses. As a result, there is a growing frequency of alloplasty procedures and combined total ankle replacement (TAR) surgeries. By performing TTR as opposed to deses, the operator avoids (i) delayed union, (ii) a shortening of the limb, (iii) a lack of mobility, and (iv) the stiffening of adjacent joints, which are the main disadvantages of joint-sacrificing procedures. Simultaneously, TTR and combined TAR offer (i) a brief period of weight-bearing restriction, (ii) quick pain relief, and (iii) preservation of the length of the limb. Here, we summarize the most up-to-date knowledge regarding AVN diagnosis and treatment, with a special focus on the role of TTR. Full article

Background/Objectives: A pronator quadratus pedicled bone graft (PQPBG) is a distal radius volar vascularized bone graft used not only for avascular necrosis of the lunate but also for scaphoid nonunion. Despite its potency and its possession of a muscular shield, this vascularized graft has a disadvantage in that the potential shortness of the muscular leash may limit the distal transfer of the bone graft. Releasing of the pronator quadratus (PQ) ulnar origin was used to enhance the distal mobility of the graft. We aimed to investigate the effect of a PQ release on the surgical outcomes of scaphoid nonunions that were operated on with the PQPBG technique. Methods: Patients with scaphoid nonunion that were treated with PQPBG from 2009 to 2020 were reviewed. Patient demographic characteristics, surgical notes, physical examinations, and radiological evaluation data were collected. Wrist range of motion, grip strength, modified Mayo wrist score, and Quick-DASH score were used to evaluate the outcomes. The included patients were divided into two groups based on the origin release status of their PQ, i.e., with and without release. Results: This study included 37 patients, 17 of whom underwent a PQ release and 20 of whom did not. The failure rates for the two groups were one and four patients, respectively, and there was no significant difference between them (p = 0.11). The postoperative mean wrist extension in the patients with a PQ release was significantly greater than that in the patients without a release (43.5 ± 6.8 vs. 36.5 ± 7.7, p = 0.0038). Although wrist flexion, ulnar deviation, radial deviation, mean outcome assessment scores, and grip strength were greater in the patients with a PQ release than in those without, no statistically significant intergroup differences were observed (p > 0.05). Conclusions: The PQPBG technique is a viable option for achieving bony union in patients with scaphoid nonunion, but it results in the postoperative restriction of wrist extension. PQ release during a graft transfer may have a favorable effect on both bone union and clinical outcomes. Full article

Introduction: Avascular necrosis (AVN) of the femoral head is a pressing orthopedic issue, leading to bone tissue death due to disrupted blood supply and affecting the quality of life of individuals significantly. This review focuses on conservative treatments, evaluating their efficacy as mainstay therapies. Enhanced understanding of AVN’s pathophysiology and advancements in diagnostic tools have rekindled interest in non-surgical interventions, emphasizing personalized, multidisciplinary approaches for improved outcomes. Material and Method: A systematic search was conducted on PubMed, SCOPUS, and Google Scholar databases from January 2020 to August 2023, with the objective of focusing on conservative treatments for AVN of the femoral head. Eligible studies, including original research, case reports, and observational studies, were examined for relevant, well-documented patient outcomes post-conservative treatments, excluding non-English and surgically focused articles without comparative conservative data. Results: A systematic search yielded 376 records on AVN of the femoral head across multiple databases. After de-duplication and rigorous screening for relevance and quality, 11 full-text articles were ultimately included for a comprehensive qualitative synthesis, focusing on conservatively managing the condition. Conclusions: This review evaluates the effectiveness of conservative treatments such as pharmacological interventions and physical modalities in managing AVN of the femoral head. Despite promising results in symptom alleviation and disease progression delay, variability in outcomes and methodological limitations in studies necessitate further rigorous, randomized controlled trials for a robust, patient-centric approach to optimize therapeutic outcomes in AVN management.

Background and Objectives: eBEACOPP is the most effective chemotherapy regimen for younger patients with early unfavorable (EU) and advanced-stage (AS) Hodgkin lymphoma (HL), albeit with significant toxicities. The 14-day/cycle prednisone course contributes to side effects, including osteoarticular events like avascular bone necrosis (AVN). Our center has been using eBEACOPP since 2009 for AS and 2014 for EU patients. In 2016, we reduced prednisone treatment to 7–10 days to lessen AVN risk. We analyzed the effects of this approach. Materials and Methods: We retrospectively collected data on patients who received at least two cycles of eBEACOPP for first-line HL treatment. Results: A total of 162 patients (33 EU, 129 AS) were included. Their median age was 31 (range 19–59 years), and 88 were males. A total of 94 patients received full corticosteroid courses, and 68 received reduced corticosteroid courses. The overall response rate (ORR) was 98%. Different corticosteroid dosings had no significant effect on ORR, febrile neutropenia episodes, or hospital admissions. After a median follow-up (mFU) of 58 months, the 5yPFS for the entire cohort was 98% vs. 95% for the standard course vs. the short corticosteroids course, respectively (p = 0.37), while the 5yOS was 98% vs. 99% for the standard course vs. short corticosteroids course, respectively (p = 0.87). In AS patients intended to be treated with six eBEACOPP cycles, 5yPFS and 5yOS were 100% vs. 97% and 100% vs. 99% for standard vs. short corticosteroid courses, respectively (p = 0.56 and p = 0.17). In EU patients, 5yPFS was 97% (standard) vs. 95% (short) (p = 0.98) and 5yOS 100% vs. 93.3% (p = 0.87). Osteoarticular events were numerically lower in patients receiving the shorter prednisone course, both in the whole cohort and in the subgroup of patients treated with six cycles of eBEACOPP, but this difference failed to reach statistical significance. Conclusions: eBEACOPP provides excellent and durable first-line disease control. Shortening the corticosteroid course does not compromise efficacy, potentially reducing toxicity. However, longer follow-ups and larger studies are needed for confirmation. Full article
