Objective: Traumatic dislocation and fracture–dislocation of the hip are rare and severe injuries often associated with high-energy trauma. Early recognition and rapid, stable reduction are essential for successful treatment; otherwise, this type of injury is associated with poor functional outcomes and high rates of complications such as avascular necrosis. This retrospective study aims to describe and analyze long-term outcomes and survival rates after a hip dislocation. Methods: Between 2008 and 2021, all patients with traumatic hip dislocation who were treated in a Level I Trauma Center were retrospectively assessed and analyzed. During the follow-up examination, two experienced surgeons carried out a clinical follow-up examination and evaluated the available X-ray images. Anterior and posterior fracture–dislocations and femoral head fractures were classified according to Stewart and Milford’s and Pipkin’s classification system, respectively. All patients were followed up using the Harris Hip Score (HHS) and Lequesne score. Results: Forty-four (38 male and 6 female) patients with a mean age of 46.02 (±19.48) years were included. The average follow-up period was 45.69 (±45.69) months. Traffic accidents were the main cause of traumatic dislocation in this series, accounting for 75% of all cases. Associated injuries were noted in 28 cases. Twenty-three and 21 patients were treated with closed and open reduction, respectively. Isolated hip dislocations without bony involvement according to Stewart and Milford type 1 occurred in five cases. Type 3 injuries were most common, followed by type 4 injuries. This study found that the type of reduction and the trauma mechanism are not significant factors in long-term prognosis (p = 0.463). Thirteen patients had subjective excellent or good results in the HHS and Lequesne score. Late post-traumatic osteoarthritis of the hip developed in 10 patients (22.7%). Patients received a hip replacement at 20.7 months (1–102) months. Thus, after 2 years, implantation of a hip prosthesis due to post-traumatic coxarthrosis was necessary in 22.7% of all cases. The type of hip dislocation classified according to Stewart and Milford had no significant influence on the implantation of a hip prosthesis. Conclusions: Excellent or good results in HHS were obtained in patients with early, stable, and accurate reduction by closed or open methods. After 2 years, 22.7% of the patients needed a total hip replacement. Full article

Background: Massive post-traumatic segmental bone defects exceeding 5 cm—particularly those resulting from Gustilo–Anderson type IIIB open fractures—present a formidable reconstructive challenge. Autologous bone graft, though biologically superior, is restricted in this context by limited harvest volume and donor-site morbidity. Nonvascularized structural bone allografts provide unrestricted graft volume and immediate mechanical support, but data on their performance in severely compromised post-traumatic environments remain sparse. Methods: This retrospective case series evaluated three patients with massive distal femoral bone loss following high-energy trauma. All were managed with a staged protocol: radical debridement and temporary joint-spanning external fixation at index surgery, followed by definitive reconstruction with a matched nonvascularized structural allograft and retrograde intramedullary nailing once the host bed was aseptic and soft-tissue coverage was established. Results: Limb salvage was achieved in all three patients at a mean follow-up of 18 months. Two patients attained stable biological integration and restored anatomical alignment; one of these progressed to full unassisted weight-bearing by four months postoperatively. The third patient developed symptomatic pseudarthrosis at the distal host–graft junction. The proximally integrated allograft had preserved sufficient femoral bone stock to serve as anchorage for a segmental total knee arthroplasty performed two years after the index reconstruction, ultimately preventing amputation. Conclusions: Nonvascularized structural allografts combined with rigid intramedullary nailing constitute a reproducible limb salvage strategy for massive femoral defects. The allograft functions not only as a vehicle for primary biological union, but as a structural reserve—maintaining femoral axis and bone stock that remains available for secondary arthroplasty reconstruction should union fail.

Objective: Femoral head fractures are rare and severe injuries often associated with high-energy trauma. Early recognition and rapid, stable reduction are essential for successful treatment to prevent complications and morbidity. This retrospective study aims to describe and analyze long-term outcomes and survival rates of the femoral head after a Pipkin fracture. Methods: Between 2012 and 2021, all patients with a femoral head fracture who were treated in a Level I Trauma Center were assessed and analyzed. Two examiners performed a physical examination and radiological control of patients and called the patients for a final follow-up. Anterior and posterior fracture-dislocations and femoral head fractures were classified according to Pipkin’s classification system. The functional outcome was assessed using the Harris Hip Score (HHS). Results: Over a 10-year period, n = 15 patients were diagnosed with a femoral head fracture. All patients were male; the average age at admission was 41.3 years. The mean follow-up was 43.7 months ± 46 months. No complications occurred in three patients (20%). Twelve patients had complications. The most common complications were nerve lesions and posttraumatic osteoarthritis. Regarding the outcome, no data were available for two patients; one patient died, and two of four patients remained with a Girdlestone resection arthroplasty at the follow-up. The mean score in HHS was 76.69 ± 20.3 (mean ± standard deviation). Conclusions: An overall complication rate of 80% was observed; however, functional outcomes were generally moderate at final follow-up. These findings highlight the considerable risk of complications associated with femoral head fractures, particularly nerve injury and posttraumatic osteoarthritis. Notably, six of 15 patients no longer retained their native hip joint at the time of assessment. The study is a Level 2b study. Full article

Background and Purpose: Surgical treatment of lower-extremity fractures can result in postoperative complications. Irrespective of specific surgical procedures, postoperative outcomes may be influenced by pre-existing comorbidities, as well as by the severity of the injury. This study investigates whether (I) internal factors and (II) external factors are associated with (III) postoperative complication rates. Material and Methods: A prospective study was conducted at a Level I trauma center between 2014 and 2018. A cohort of 416 patients with surgical treatment after traumatic long bone fractures of the lower extremities was assessed, with comorbidities along with factors such as age, malnutrition, and impaired mobility systematically evaluated. Injury severity was classified using the Abbreviated Injury Scale; fracture type and location using the AO/OTA classification; and postoperative complications using the Clavien–Dindo system. Results: Across the cohort, internal factors such as immobility and malnutrition were associated with an increased complication rate. Age showed a weak correlation. Obesity demonstrated a trend toward a protective effect. Patients with femoral fractures exhibited a higher prevalence of cardiovascular comorbidities, with heart failure representing the most pronounced risk factor. In the subgroup with lower leg fractures, chronic heart disease also remained a significant predictor of complications. Correlation analysis further revealed a significant positive association between injury severity and the occurrence of complications across the overall cohort. Conclusions: This study provides valuable insights into risk factors for complicated postoperative courses. Injury severity appears to be a promising predictor of complication risk in patients with leg fractures. Reduced mobility and malnutrition, likewise, were significantly associated with increased complication rates; these may represent the most readily addressable modifiable risk factors. All data were collected using validated, user-friendly classification systems that may be suitable for predictive modeling. Full article

Background/Objectives: The Kocher–Langenbeck approach is widely used for surgical fixation of posterior acetabular wall fractures. While previous studies have focused on mechanical outcomes and the risk of post-traumatic osteoarthritis, the effects on peripheral circulation and neuromuscular recovery remain underexplored. This study aimed to evaluate dynamic changes in neuromuscular function and microcirculation following open reduction and internal fixation (ORIF) using this approach. Methods: A retrospective analysis was conducted on 34 patients (aged 23–75) treated for posterior acetabular wall fractures between 2014 and 2022. All patients underwent ORIF via the Kocher–Langenbeck approach. Assessments at 8 and 12 months postoperatively included electromyography (EMG), chronaximetry, and rheovasography (RVG). Asymmetry coefficients were calculated to quantify blood flow and functional differences. Results: At 12 months postoperatively, significant microcirculatory asymmetry persisted in the operated limb, with arterial and venous coefficients exceeding 25% (27.5% and 26.8%, respectively). EMG revealed sustained reductions in gluteus maximus and rectus femoris activity (asymmetry ~39%). Chronaximetry showed delayed nerve conduction recovery, particularly in the common peroneal nerve (AC = 44%). The femoral segment demonstrated the most severe impairment in both arterial inflow and venous outflow. Conclusions: ORIF via the Kocher–Langenbeck approach is associated with long-term disturbances in neuromuscular function and regional circulation. Further research should explore alternative surgical approaches (e.g., ilioinguinal, Stoppa) in prospective studies, assess vascular integrity using advanced imaging (e.g., contrast-enhanced ultrasound), and incorporate long-term functional outcomes. Studies on neurovascular-sparing techniques and optimised rehabilitation protocols may help reduce postoperative morbidity and improve recovery. Full article

Background/Objectives: Modular dual mobility (MDM) cups are constituted by a cobalt-chromium liner inserted into a standard acetabular shell, allowing for intraoperative indication and supplementary screw fixation of the acetabular component. MDM could face mechanical and biological issues, with the associated risk of elevated blood metal ions levels and adverse local tissue reactions. Methods: This is a monocentric retrospective study on a consecutive series of 105 patients who underwent primary unilateral THA with the G7 Dual Mobility Acetabular System cup (Zimmer Biomet, Warsaw, IN, USA) from March 2019 to April 2023, and who were evaluated clinically and radiographically at a minimum two-year follow-up. All complications and revisions were recorded. Survivorship analysis with any revision surgery as endpoint was performed using Kaplan–Meier survival curves. Results: There were eighty-nine patients (follow-up rate 84.8%) who underwent clinical and radiographic follow-up. The mean follow-up was 2.5 ± 0.8 years. Revision-free survival was 98.0%. Three complications (2.8%) were recorded: one case of posterior dislocation, one periprosthetic joint infection and one post-traumatic periprosthetic femur fracture. Dislocation rate and infection rate were less than 1.0%. None of the patients were revised for adverse local tissue reactions. No cup loosening was observed. No cases of intraprosthetic dislocation, liner malseating or femoral notching were observed. Retroacetabular stress shielding was present in 43.0% of patients. Clinical scores significantly improved at the last follow-up compared with preoperative status (p < 0.0001): the final mean mHHS was 87.5 ± 5.3 and the final mean VAS was 0.5 ± 0.9. Conclusions: The Zimmer G7 modular dual mobility cup appears to be a safe and effective option and does not present specific implant-related mechanical and biological issues in primary total hip arthroplasty at a minimum two-year follow-up.

Background: Post-traumatic osteomyelitis (PTO) of the lower extremity is among the most demanding problems in orthoplastic reconstructive surgery. It typically follows open fractures, failed osteosynthesis, or implant infection. Effective management requires coordinated infection control, stable skeletal fixation, and timely vascularized soft-tissue coverage. Methods: We conducted a retrospective case series of 20 consecutive patients with PTO of the lower limb treated between 2021 and 2024 at a tertiary orthoplastic center. All patients underwent radical debridement, culture-directed intravenous antibiotic administration, and soft-tissue reconstruction using local muscle, fasciocutaneous, or free flaps; vascularized bone flaps were used to select nonunion cases. The primary outcomes were flap survival, complications, infection resolution, and limb salvage. Exploratory analyses included descriptive subgroup summaries by flap category. Results: Among 20 patients (15 men, 5 women; mean age 53.6 years), reconstructions included reverse/pedicled sural flaps (n = 9), hemisoleus muscle flaps (n = 7), medial gastrocnemius muscle flaps (n = 2), peroneus brevis muscle flaps (n = 2), and free flaps (n = 6), which comprised anterolateral thigh (ALT), medial femoral condyle (MFC) osteoperiosteal, deep circumflex iliac artery (DCIA) osteocutaneous, and radial forearm free flaps (RFFFs). Single-flap reconstructions were performed in 13 cases, whereas multistage/multiflap strategies were used in 7. Overall flap survival was 90%. Major flap complications comprised partial necrosis in two reverse sural flaps and one complete loss of a reverse sural flap; two patients had minor wound dehiscence. Infection resolved in 18/20 patients (90%; 95% CI ≈ 0.70–0.97). One patient requested below-knee amputation due to persistent nonunion associated with a pathological fracture. At a mean 10-month follow-up, all limb-salvaged patients were ambulatory. Conclusions: Effective reconstruction of PTO is improved by using a patient-specific algorithm that considers the defect location, vascular status, and host comorbidities. Local muscle and fasciocutaneous flaps remain dependable for most defects, with free or vascularized bone flaps reserved for composite or recalcitrant cases. Early referral to high-volume centers, radical debridement, and orthoplastic collaboration are critical for optimizing limb salvage. Our findings should be interpreted in light of the study’s retrospective design and small sample size. Full article

Open reduction and internal fixation (ORIF) is widely regarded as the primary treatment for acetabular fractures, but limitations arise in complex cases, leading to non-anatomical reductions and increased risk of post-traumatic osteoarthritis. Given the high incidence of secondary arthritis (12–57%) following ORIF, total hip arthroplasty (THA) is often necessitated, particularly in scenarios unsuitable for ORIF, such as extensive comminution or combined femoral head and neck fractures. The surgical landscape has shifted from a traditional “fix or replace” to a more integrated “fix and replace” approach, especially beneficial in managing elderly patients with osteoporotic bones. THA is applied across various timelines, including acute (0–3 weeks), delayed (3 weeks to 3 months), and late (beyond 3 months), each presenting distinct challenges and requiring specific strategies to optimize outcomes. The importance of precise bone defect classifications and the role of dual mobility cups in reducing dislocation risks are highlighted, alongside the use of modern surgical and fixation techniques to improve stability and patient outcomes. Enhanced recovery protocols and meticulous postoperative management are critical to addressing complications, such as infections and hardware interference, tailoring treatment approaches to each patient’s needs, and advancing care for complex acetabular fractures.

Introduction: Intertrochanteric femoral fractures (IFFs) are the most common traumatic injuries in elderly people and significantly impact the patient’s health status. The current evidence indicates that short intramedullary nails may be a better choice than dynamic hip screws in IFF management, being less invasive and biomechanically superior, providing a buttress to limit fracture collapse. On the other hand, an unstable fracture may collapse even after adequate reduction and fixation. This paper aims to describe the surgical complexity of the nail-to-total hip arthroplasty (THA) conversion, focusing on the restoration of normal hip geometry. Material and Methods: Patients referred to our level I trauma center with failed cephalomedullary nailing following IFFs and managed with the nail-to-THA conversion were retrospectively recruited. The anteroposterior postoperative pelvis radiographs were analyzed to establish whether the normal biomechanics of the involved hip were restored. The following radiographic parameters were recorded and compared to the contralateral unaffected side: hip offset, cervical–diaphyseal angle, and limb length discrepancy. Clinical assessment was performed using the following scores: the Harris hip score (HHS) and the visual analog scale for pain (VAS). The independent samples t-test and the Pearson correlation test were performed. The tests were two-tailed; a p < 0.05 was considered significant. Results: A total of 31 patients met the inclusion and exclusion criteria (10 males and 21 females; mean age: 76.2 years; range: 66–90 years) and were included in this study. The modes of trochanteric nail failure included the following: cut-out in 22 cases (70.97%), non-union in 4 cases (12.9%), peri-implant fracture in 1 case (3.23%), cut-through in 2 cases (6.45%), and femoral head avascular necrosis (HAN) in 2 cases (6.45%). Long stems were used in 21 patients out of 31 (67.74%), while dual-mobility cups were implanted in 24 patients out of 31 (77.41%). A significant mean neck shaft angle (NSA) increase (p < 0.001) and a significant mean femoral offset reduction (FO, p 0.001) compared to the contralateral hip were recorded; a mean limb length discrepancy (LLD) of 8.35 mm was observed. A significant correlation between HHS and ∆NSA (p = 0.01) and ∆FO (p = 0.003) was recorded. Conclusions: Conversion from a cephalomedullary nail to THA is a complex procedure that should be considered a revision surgery, rather than a primary surgery. Surgeons must be aware that normal hip geometry may not be obtained during this surgical procedure; thus, a patient undergoing the nail-to-THA conversion for intertrochanteric fixation failure may have an increased risk of implant-related complications.

Background/Objectives: Osteoporosis is an important health issue worldwide, and bisphosphonates are commonly prescribed for its treatment. However, certain complications can occur with long-term bisphosphonate therapy. The complication highlighted in this study was atypical femoral fractures, which are rare but significant. The orthopedic consensus identifies surgical intervention as the gold-standard treatment for atypical femoral fractures, typically involving intramedullary or cephalomedullary nailing (CMN). The aim was to monitor patients for a follow-up period exceeding six months after surgical fixation with a CMN, with the majority of patients being followed up for more than 18 months after their initial surgery. Methods: This single-center analysis was conducted on a mixed cohort comprising a total of 10 patients. The study was conducted between September and November 2024. The inclusion criterion was surgical treatment for bisphosphonate-related atypical femoral fractures (AFFs) between June 2022 and November 2024 at a Level 1 Trauma Center, Cork University Hospital in the Republic of Ireland. The patients were monitored through a structured follow-up protocol that extended beyond six months, with the majority of patients being followed up for over 18 months. Follow-up assessments were conducted at defined intervals, including key evaluations at 3 and 6 months and at their final review. Clinical parameters such as pain, functional recovery, and radiological healing were considered. Results: No significant functional difference was observed at follow-up between the patients who sustained displaced fractures and those who presented with undisplaced fractures. Sixty percent of the patients remained pain-free from the 3-month postoperative follow-up, and the same percentage continued to be pain-free at the final follow-up. Conclusions: Cephalomedullary nailing is a safe option for the treatment of atypical femoral fractures. Patients with a bisphosphonate atypical femoral fracture should undergo bilateral screening and should be followed up for a longer period than the standard post-traumatic care intervals that are in place for typical femoral fractures.

Controlling pain after major orthopedic surgery may be challenging, and it is related to delayed recovery, the development of chronic pain, and analgesic dependence. It is well known that effective postoperative pain control can reduce hospital stays by ensuring a more rapid rehabilitation,
thereby decreasing the overall costs. Despite the development of analgesics, the use of opioids and their derivates remains the cornerstone of treatment for patients with acute moderate-to-severe pain in association with general or regional anesthesia. To reduce the risk of side effects and opioid addiction, considering the alarming epidemiological reports in relation to opioid abuse, combined analgesic methods are used, in addition to lower dosages or different forms of administration, such as transdermal administration. Fentanyl transdermal patches appear to be effective in controlling postoperative pain as part of multimodal analgesic regimens in knee and hip surgery, shoulder arthroplasty, traumatic fractures, and one-day surgery; this treatment has fewer associated side effects and can be safely used even in patients with renal impairment. It is also recommended for postoperative pain management in combination with a femoral–sciatic nerve block during foot and ankle surgery. Full article

Background: Femoral head fractures with osteochondral defects are rare injuries often resulting from traumatic hip dislocations. These injuries create a significant risk for post-traumatic osteoarthritis. Various surgical methods for repair have been utilized to restore these osteochondral defects, including mosaicplasty, autologous cartilage implantation, osteochondral allograft transplant (OAT), and demineralized bone matrix (DBM). Methods: We present a case of a 21-year-old male who sustained a fracture-dislocation of the left femoral head with impaction of the weight-bearing surface due to a motor vehicle collision. Due to the patient’s relatively young age, OAT plugs from a fresh-frozen proximal humerus with DBM supplementation during fracture fragment fixation were chosen to reduce the likelihood of post-traumatic arthritis. Results: The patient regained subjective function and full strength on exam with no pain at 2 years postoperatively. Conclusions: We propose that a proximal humerus allograft is a suitable alternative in an urgent setting when a femoral head allograft is not available. Full article

Background: Fibrous dysplasia (FD) is a rare condition in which normal spongy and cortical bone is replaced by non-neoplastic fibrous tissue, leading to weakened bone matrix and increased risk of pathological fractures and deformities. Treating these deformities poses a significant challenge for surgeons. While various cases of surgical stabilization and limb lengthening using intramedullary nails have been reported, there is limited evidence on the use of Motorized Intramedullary Limb-Lengthening Nails (MILLNs) in FD patients. This case report presents the clinical history of a patient with FD who underwent multiple surgical interventions to address severe lower limb length discrepancy (LLD) and angular deformity caused by multiple fractures. Case presentation: A sixteen-year-old Caucasian girl with polyostotic FD developed a severe post-traumatic LLD of 10 cm on the right side, associated with coxa vara, valgus knee, and patellar instability. The deformity of the proximal femur was addressed with a valgus and derotational femoral osteotomy. However, this procedure exacerbated the knee’s valgus deformity and only partially corrected the LLD, leading to the decision to proceed with femoral lengthening. A retrograde magnetic intramedullary nail (PRECICE, NuVasive) was utilized for this purpose. Approximately three months postoperatively, radiographs revealed the loosening of the proximal anchoring screw, while the nail had reached maximum distraction. We then proposed reactivating the previously implanted nail. Nine months after the final surgery, standing long-leg radiographs showed a residual shortening of 1 cm, with excellent healing at the fracture sites and the nail and screws remaining securely in place. The patient was monitored regularly, with the latest follow-up occurring four years and five months after the conclusion of the last lengthening procedure. Conclusions: This case report describes the reactivation of a MILLN in a patient with polyostotic fibrous dysplasia. While nail reactivation has been previously described in the literature, to our knowledge, it has not been reported for treating complications arising from FD. In cases of mechanical complications, this approach can equalize leg length discrepancies and correct deformities, avoiding additional invasive surgeries and reducing healthcare costs. As this is an off-label treatment, preoperative consent from both the patient and the parents is required. Full article

Life expectancy and overall function of amputated patients have improved significantly over the last few decades; for this reason, amputees are more exposed to primary or secondary degenerative disease of the hip, requiring total hip arthroplasty (THA) surgery. However, during training, not all the surgeons acquire adequate skills to manage these patients, and only a few studies and case reports describe technical pearls and outcomes of THA in patients with ipsilateral lower limb amputation, either above or below the knee. The objective of this narrative review is to present current evidence and surgical tips for performing THA in ipsilateral amputated patients, with a focus on the differences between patients with above- (AKA) and below-knee amputation (BKA). We reviewed manuscripts in major scientific databases, cross-referencing to retrieve adjunctive manuscripts, and summarized all relevant cases. We found 17 manuscripts, spanning 70 years of literature, collecting a total of 39 patients who underwent THA on an ipsilateral amputated limb: 13 AKA, 23 BKA, and 3 through-knee-amputation (TKA). The cohort primarily consists of patients with post-traumatic hip arthritis, often associated with sequelae such as fractures to other bones, soft tissue compromise and heterotopic calcifications. Managing with amputated patients requires careful planning, which includes the study of the residual bone, muscle anatomy, and the level of femoral amputation, as these factors present significant surgical challenges, especially in patients without a knee joint. In dealing with the post-traumatic and multi-comorbidity patients, rehabilitation goals should be considered prior to surgery and should drive the surgical strategy. We found that BKA patients typically have high functional demands, necessitating precise positioning of the components and an aggressive post-operative physiotherapy regimen to avoid unsatisfactory outcomes. AKA patients, on the other hand, often present with altered anatomy, and typically require more surgical instruments and expertise to achieve intraoperative dislocation of the hip joint.

The biomechanical efficacy of nail–plate constructs (NPCs) used in the treatment of traumatic distal femur fractures (DFFs) remains understudied compared to traditional approaches. This systematic review examines the biomechanical efficacy of NPCs compared to alternative approaches for the surgical fixation of DFFs to guide surgical decision-making and improve patient outcomes. This systematic review searched the PubMed, CINAHL, MEDLINE, Web of Science, and SPORT Discus databases from inception until 24 January 2024. Inclusion criteria were biomechanical studies that involved nail–plate combination constructs for DFFs. Six observational studies were included. Of the included studies, five studies utilized synthetic bone models in testing, and one study used both synthetic and cadaveric bone models. All studies found NPCs to have significantly higher axial and torsional stiffness and resistance to loading than distal lateral femoral locking plate (DLFLP) constructs. The 11 mm NPCs were significantly stiffer than the 9 mm NPCs under torsional and axial loading. Only one of two studies found NPCs to have greater axial stiffness than dual-plate (DP) constructs. NPCs and DP constructs had greater torsional and axial stiffness than the plate-only or DP with medial distal tibial plate constructs. NPCs had less displacement and torque than the plate- or nail-only constructs under axial and torsional loads. NPCs demonstrate superior axial and torsional stiffness and resistance to mechanical loads compared to DLFLP. The varying performance between 11 mm and 9 mm NPCs suggests that construct diameter plays a role in mechanical stability. NPCs and DP constructs performed better than plate-only constructs. Future research should explore the impact of varying nail diameters and plate configurations on stability, as well as the clinical efficacy of NPCs across different patient populations, particularly those with varying bone densities, to better understand their performance in real-world scenarios.
