Background: The global increase in orthopedic implant use—both for trauma fixation and arthroplasty—has profoundly transformed musculoskeletal surgery. As a consequence, fractures occurring in the presence of implants have become more frequent and clinically relevant. Yet, these injuries are currently described using highly heterogeneous terminology, including periprosthetic (fracture occurring in the presence of a prosthetic joint replacement) peri-implant (fracture occurring around an osteosynthesis or fixation device), implant-related, and hardware-related fractures (umbrella terms encompassing both prosthetic and fixation devices, used descriptively rather than classificatorily). This coexistence of multiple, context-specific terminologies hinders clinical communication, complicates registry documentation, and limits research comparability across orthopedic subspecialties. Because fractures occurring in the presence of orthopedic implants significantly alter load transfer, muscle force distribution, and musculoskeletal biomechanics, a clear and unified terminology is also relevant for muscle-focused research addressing implant–tissue interaction and functional recovery. Objective: This systematic review aimed to critically analyze the terminology used to describe fractures influenced by orthopedic implants, quantify the heterogeneity of current usage across anatomical regions and publication periods, and explore the rationale for adopting a unified umbrella term—“artificial fracture.” Methods: A systematic search was performed in PubMed, Scopus, and Web of Science from January 2000 to December 2024, following PRISMA guidelines. Eligible studies included clinical investigations, reviews, registry analyses, and consensus statements explicitly employing or discussing terminology related to implant-associated fractures. Data were extracted on publication characteristics, anatomical site, terminology employed, and classification systems used. Quantitative bibliometric and qualitative thematic analyses were conducted to assess frequency patterns and conceptual trends. Results: Of 1142 records identified, 184 studies met the inclusion criteria. The most frequent descriptor in the literature was periprosthetic fracture (68%), reflecting its predominance in arthroplasty-focused studies, whereas broader and more practical terms such as implant-related and peri-implant fracture were more commonly used in musculoskeletal and fixation-related research. Terminological preferences varied according to anatomical site and implant type, and no universally accepted, cross-anatomical terminology was identified despite multiple consensus efforts. Discussion and Conclusions: The findings highlight persistent heterogeneity in terminology describing fractures influenced by orthopedic implants. A transversal, descriptive framework may facilitate communication across subspecialties and support registry-level harmonization. Beyond orthopedic traumatology, this approach may also benefit muscle and musculoskeletal research by enabling more consistent interpretation of data related to muscle–bone–implant interactions, rehabilitation strategies, and biomechanical adaptation.

Background/Objectives: Cleft lip and/or palate are common craniofacial anomalies whose surgical repair is classified as clean-contaminated and may be complicated by surgical site infection or palatal fistula. Despite widespread perioperative antibiotic use, there are no standardized, evidence-based recommendations, and rising antimicrobial resistance underlines the need for rational prescribing. This systematic scoping review aimed to map current evidence on prophylactic antibiotic therapy and related perioperative measures in cleft surgery. Methods: A scoping review was conducted using the Arksey and O’Malley framework and reported in line with PRISMA 2020. PubMed, Mendeley and Google Scholar were searched (January 2015–10 February 2025) for English-language retrospective studies, clinical trials, survey studies and systematic reviews concerning prophylactic antibiotics, bone grafting procedures, mouthwash use or oral microbiota in patients undergoing cleft lip and/or palate surgery. Six reviewers independently screened records; two experienced clinicians extracted data on study characteristics, antimicrobial regimens and infectious or microbiological outcomes. Given heterogeneity and the scoping aim, no formal risk-of-bias assessment or meta-analysis was performed. Results: A total of 40 studies met the inclusion criteria, including 21 original research articles. Considerable variation in antibiotic choice, timing and duration was observed, with no clear superiority of any regimen. Single-dose perioperative prophylaxis appeared non-inferior to prolonged courses in several settings. Oral microbiota studies highlighted colonization by resistant and opportunistic pathogens in cleft patients. Conclusions: Current evidence supports individualized, often short-course perioperative antibiotic strategies rather than routine prolonged therapy. High-quality randomized and microbiological studies are required to develop standardized, resistance-conscious guidelines. Full article

Background: Hyperbaric oxygen therapy (HBOT) is considered a potential adjunctive modality to enhance tissue regeneration in oral and maxillofacial surgery. By increasing tissue oxygen availability, HBOT may support bone and soft-tissue repair under hypoxic and chronically inflamed conditions. Aim: This narrative review evaluates current experimental and clinical evidence regarding HBOT in high-risk dental indications, including osteoradionecrosis (ORN), medication-related osteonecrosis of the jaw (MRONJ), chronic osteomyelitis, poorly healing postoperative wounds, and procedures in patients with systemic comorbidities. Methods: A structured search of PubMed, Web of Science, and the Cochrane Library identified 123 relevant English-language publications (from 1 January 2000–September 2025) addressing HBOT mechanisms and clinical applications in oral and maxillofacial surgery, including clinical trials, observational studies, preclinical models, and systematic reviews. Results: Available evidence suggests that HBOT may improve healing outcomes and reduce complication rates in early-stage ORN and MRONJ when used as an adjunct to surgery and systemic therapy. However, findings in implantology—particularly in irradiated or diabetic patients—and in periodontal therapy remain limited, heterogeneous, and methodologically inconsistent. Conclusions: HBOT may be considered in selected clinical scenarios, particularly where healing is impaired by hypoxia or systemic disease. Nevertheless, current evidence remains insufficient to support routine use. Standardized, high-quality studies with clearly defined endpoints and uniform therapeutic protocols are needed to determine its clinical effectiveness and optimal indications. Full article

Background/Objectives: Surgical management of atypical femoral fractures (AFFs) stabilized with intramedullary (IM) nailing is frequently challenged by delayed union or nonunion due to the severely suppressed bone turnover characteristic of bisphosphonate-related bone pathology, often leading to a hypertrophic nonunion-like state at the fracture site. This consecutive case series aimed to evaluate the effectiveness of intraoperative percutaneous decortication at the hypertrophic cortex in promoting rapid bone healing in complete AFFs. Methods: This was a single-center consecutive case series of patients with complete atypical femoral fractures (AFFs) treated with intramedullary nailing and adjunctive percutaneous decortication since February 2021. The standardized surgical protocol—including percutaneous decortication performed through a small anterolateral incision using an osteotome to create bone chips and stimulate the sclerotic cortex—was applied prospectively to all consecutive patients from February 2021. Of the 20 patients who underwent surgery during this period, 14 with sufficient radiographic follow-up were included in the final retrospective analysis. Data collected included patient demographics, duration of bisphosphonate use, fracture location (diaphyseal vs. subtrochanteric), operative details (including iatrogenic fracture), and radiographic bone union time. Bone union was assessed on serial radiographs by two independent observers. Results: All 14 patients were female, with a median age of 75 years (IQR 67–79 years). Thirteen patients (92.9%) had prior bisphosphonate exposure for a median of 4.5 years (IQR 3–10 years). Six fractures were subtrochanteric fractures, and six were complicated by iatrogenic fracture during nail insertion. Postoperative teriparatide was administered to six patients. Radiographic bone union was achieved in all 14 patients at a median of 19 weeks (IQR 16–22 weeks; range 16–24 weeks). No major complications (infection, implant failure, nonunion, or neurovascular injury) occurred during follow-up. Conclusions: Percutaneous decortication is a simple, safe, and biologically plausible adjunct to intramedullary nailing. In this series of 14 elderly women with long-term bisphosphonate exposure (median 4.5 years), the technique was associated with 100% radiographic union at a median of 19 weeks without major complications, suggesting a promising strategy that warrants validation in larger, controlled trials.

Background/Objectives: The aim of this study is to evaluate pretreatment osseous changes in the temporomandibular joint (TMJ) in orthognathic surgery patients using cone-beam computed tomography (CBCT) and to determine the distribution of the findings according to sagittal skeletal malocclusion groups. Methods: CBCT images of 103 patients (206 condyles) were retrospectively analyzed. Patients were classified as Class I, II, and III based on ANB angles. Condylar morphology was assessed for flattening, sclerosis, erosion, osteophyte formation, and subchondral bone cysts. All evaluations were performed by a single investigator (κ = 0.87). Group differences were analyzed using the chi-square test with Bonferroni correction (p < 0.05). Results: The most frequent alteration was flattening (29.6%), followed by sclerosis (11.2%), erosion (10.7%), osteophyte formation (8.3%), and subchondral bone cysts (4.4%). No significant sex-related differences were found (p > 0.05). A significant difference was observed only in sclerosis (p = 0.049), which was more prevalent in Class I than Class III. Flattening predominated in all groups, while erosion and osteophytes were more common in Class II, and sclerosis was more frequent in Class I. Conclusions: This study demonstrated that condylar flattening was the most common morphological alteration in orthognathic patients across all skeletal malocclusion groups. The higher prevalence of sclerosis in Class I compared with Class III suggests that mandibular positioning may influence adaptive and degenerative remodeling processes of the TMJ. This study emphasizes the importance of CBCT evaluation for detecting osseous changes in TMJ before orthognathic surgery and demonstrates that pre-existing alterations may impact surgical stability and postoperative functional outcomes.

Background/Objectives: Chronic bone infections require local antimicrobial delivery to achieve high drug concentrations while limiting systemic toxicity. Silver ion-doped calcium phosphate synthetic bone grafts have been proposed as carriers for local antimicrobial release. This study aimed to evaluate the efficacy and safety of a silver ion-doped synthetic bone graft in patients with chronic osteomyelitis, infected nonunion, or implant-related bone infection. Methods: This retrospective cohort included 12 adults who underwent surgery for chronic osteomyelitis or implant-associated infection. All patients received thorough debridement, removal of infected implants when present, and filling of bone defects with a silver ion-doped calcium phosphate graft. The median age was 38 years, and follow-up was 12 months. Clinical and radiographic outcomes, liver and kidney function tests, and blood silver levels were assessed pre- and postoperatively. Results: Infection eradication was achieved in 11 of 12 patients (90%) at 12 months. Functional recovery, defined as return to normal daily activities, occurred within 3–5 months. Bone union was observed in all but one patient within 3–6 months, and no graft resorption was detected at one year. No significant differences in liver or kidney function tests were found compared with the control group (p > 0.05), and blood silver levels remained within normal limits. Conclusions: At 12-month follow-up, silver ion-doped synthetic bone grafts showed encouraging safety and efficacy in the treatment of chronic osteomyelitis. These findings suggest that silver-doped grafts may represent a useful option for one-stage treatment of osteomyelitis. Full article

Background: Osteoporosis and low bone mineral density are highly prevalent among patients undergoing spinal fusion, contributing to higher rates of hardware failure, revision surgery, and poor postoperative outcomes. Despite clear risks, perioperative screening and treatment for osteoporosis remain inconsistent. Bone Health Clinics (BHCs) and Fracture Liaison Services (FLSs) have emerged as multidisciplinary models to address this care gap. We describe the implementation of a dedicated BHC at a single academic center and evaluate perioperative pharmacotherapy patterns, treatment barriers, and surgical outcomes among spine patients. Methods: We retrospectively reviewed 174 consecutive perioperative spine patients referred to our institutional BHC between October 2019 and April 2024. Demographics, surgical characteristics, bone health status, laboratory and DXA results, pharmacologic management, contraindications, insurance-related barriers, and medication sequencing were collected. Surgical outcomes included hardware failure and revision surgery. Bone health response was assessed by follow-up DXA scans. Results: The cohort was predominantly female (78.2%) with a mean age of 71.9 years. Most patients were referred by neurosurgery (53.4%) or orthopedics (41.4%). Based on DXA and fragility fracture history, 27.0% had osteopenia, 56.3% osteoporosis, and 13.8% severe osteoporosis. Pharmacotherapy was prescribed in 146 patients (83.9%), most commonly romosozumab (32.9%), denosumab (22.6%), and abaloparatide (21.2%). Twenty-eight patients (16.1%) did not receive medication, primarily due to contraindications. Insurance-related barriers disproportionately affected anabolic agents, whereas denosumab had the lowest denial rate (15.2%, p = 0.0124). Sequential therapy was common (32.1%), most frequently romosozumab followed by denosumab. Hardware failure occurred in 11.5% of patients, with 5.7% requiring revision surgery. Among the 80 patients (46.0%) with follow-up DXA, 60% demonstrated improved bone mineral density, with an average T-score gain of 0.6 ± 0.5. Conclusions: Integration of a multidisciplinary BHC into perioperative spine care was feasible, associated with high rates of pharmacotherapy initiation, and demonstrated favorable early surgical outcomes compared to published complication rates in this population. Insurance and contraindications remain key barriers to anabolic therapy access, driving prescribing toward denosumab. Prospective studies are needed to confirm the impact of perioperative bone optimization on surgical durability, cost-effectiveness, and patient-centered outcomes. Full article

Cervicofacial actinomycosis is a well-recognized infectious disease caused by Actinomyces, a Gram-positive filamentous bacterium. In contrast, Nocardia, a morphologically similar, hyphae-forming organism, is an exceedingly rare cause of cervicofacial abscesses, and even more uncommon associated osteomyelitis of mandible. We present such a case involving a kidney transplant recipient who presented with opioid-induced constipation, along with left jaw pain and swelling. CT scan of the soft tissue in the neck revealed a complex cervicofacial abscess with enhancement of underlying mandible. Culture growth and RNA sequencing of USG-guided aspirate identified a Nocardia species closely related to N. beijingensis/exalbida. The patient initially received broad-spectrum antibiotics, including ceftriaxone, imipenem, and trimethoprim-sulfamethoxazole (TMP-SMX). Imipenem was later discontinued in view of new-onset unexplained encephalopathy and replaced with linezolid, which was subsequently switched to minocycline following thrombocytopenia development. Minocycline therapy was intended for a total of 12 months. TMP-SMX was avoided long-term due to avoid nephrotoxicity risk in kidney transplant patients. On six-month follow-up, the patient showed clinical and radiological improvement; minocycline was discontinued after additional six months. This case highlights the importance of considering Nocardia as a differential diagnosis in immunosuppressed patients presenting with cervicofacial symptoms, especially following orofacial surgery or trauma. Early recognition, prompt diagnosis, and appropriate antibiotic therapy with adequate bone penetration seem crucial for optimal management and may help avoid the need for surgical intervention.

Background and Objectives: Odontogenic sinusitis (ODS) is a particular type of sinus infection induced by dental infections or iatrogenic causes. Although not rare, it is often underrated and sometimes confused with other forms of chronic rhinosinusitis. The aim of this review was to summarize the main diagnostic aspects, microbiological profile, and current options in the therapeutic management of ODS. Materials and Methods: Recent studies and consensus statements from both dental and ENT fields were reviewed. The focus was on the ODS diagnostic criteria, the types and the timing of dental and endoscopic treatment approaches, and treatment combinations inducing the best outcomes in ODS. Results: ODS usually involves anaerobic bacteria such as Fusobacterium and Peptostreptococcus. Empirical antibiotics like amoxicillin or amoxicillin–clavulanate are most often used, but antibiotic therapy alone rarely cures the disease. Dental treatment is essential in ODS cases with oroantral fistulas, infected maxillary sinus bone grafts, or implants. However, in these clinical situations, concurrent one-stage dental and endoscopic sinus surgery (ESS) treatment seems to offer the highest success rate, close to 97%. Combined surgery significantly improved ODS treatment outcomes in terms of reduced reintervention rates and recurrence. There is still debate on how wide ESS should be in uncomplicated ODS, but many reports show that maxillary antrostomy alone can be sufficient. In apical periodontitis-related ODS, recurrence after primary ESS is uncommon in the short term. Conclusions: ODS management needs cooperation between ENT and dental specialists. Treating the dental underlying infection remains critical to prevent oral or systemic complications. Future research should better define diagnostic criteria, antibiotic use guidelines, and the best timing for combined surgery. New studies on microbiology, immunity, and artificial intelligence could help improve diagnosis and medical care of ODS patients. Full article

Despite advances in staged protocols and fixation techniques, treatment of pilon fractures remains a significant challenge in orthopedic trauma, with up to 21% of patients requiring revision surgery. Management of a pilon fracture that has failed initial treatment involves navigating a myriad of complicating variables, including infection, bone loss, malalignment, and nonunion. Although no single surgical approach can be aptly applied to the broad range of pathology and severity spanned by these patients, this narrative review provides a systematic framework for developing a revision pilon reconstruction plan. We present a protocol for pre-operative assessment and review current techniques for infection eradication, bone defect management, deformity correction, and joint-preserving versus joint-sparing surgery. These fundamental strategies form the foundation of a successful salvage plan and can be personalized to address specific fracture morphology, host factors, and goals of care. Full article

Aim: Periprosthetic fracture-related infections (PFRIs) are a serious complication of total arthroplasty, with incidence rates increasing in line with the growing number of joint replacements. PFRI can lead to prolonged hospitalization, multiple surgical procedures and suboptimal functional outcomes. The diagnosis of PFRI remains challenging due to the overlap of clinical symptoms with other post-traumatic conditions, and identification of the pathogen often fails through conventional methods. This study also highlights the importance of a personalized medicine approach in managing PFRI, where diagnostic and therapeutic decisions are tailored to the individual patient’s comorbidities, immune status and bone healing capacity. By integrating clinical, microbiological and imaging data, our findings support precision-based strategies to optimize outcomes and minimize complication. Methods: This retrospective case series was conducted at the Unit of Osteoarticular Infection of the University of Turin, Italy, from January 2018 to December 2023. Patients who developed septic complications after open reduction and internal fixation (ORIF) of periprosthetic fractures involving hip or knee implants were included. The infection was diagnosed in accordance with established guidelines, and treatment decisions were based on clinical, microbiological and radiological findings. Results: In the present study, periprosthetic fractures complicated by infections were identified in nine patients (5.4%), constituting a small but significant subset of cases. The cases were then categorized into four clinical scenarios based on the following variables: joint involvement, fracture healing and infection progression. Scenario A, involving fractures without prosthetic involvement and unhealed fractures, included three patients (33%) and was treated with debridement and change of the fixation device. Scenario B, involving fractures without prosthetic involvement but with healed fractures, involved one patient (11%), where the ongoing infection was confirmed despite the healed fracture and where the device could be removed. The third scenario (C), which pertains to cases involving prosthetic involvement, included three patients (33%) who required replacement or removal of the prosthesis and, in some cases, a second stage. The fourth scenario, involving patients with limited operability, included two patients (22%) for whom no surgery was performed. Despite the significant clinical challenges encountered, the paucity of literature on the management of periprosthetic fractures with septic complications is limited, highlighting the need for further research in this understudied area. Conclusions: PFRI remains a challenging complication that necessitates a multidisciplinary approach to diagnosis and treatment. Despite advances in imaging and microbiological testing, the early detection and identification of pathogens remain challenging, emphasizing the necessity for enhanced diagnostic methods. This study offers valuable insights into the management of PFRI and provides a foundation for future research to develop optimal diagnostic and therapeutic strategies. Full article

Osteoarticular infections (OAIs), including osteomyelitis, septic arthritis, prosthetic joint infections, and facture-related infections, remain a major challenge due to biofilm formation and the prevalence of multidrug-resistant (MDR) pathogens. Although OAIs are predominantly caused by Staphylococcus aureus and coagulase-negative staphylococci, the increasing incidence of MDR Gram-negative infections adds further complexity to their management. Standard approaches, combining surgery and prolonged antibiotic therapy, frequently result in recurrence and poor outcomes. Bacteriophage (phage) therapy has emerged as a promising adjunct or alternative approach, offering high host specificity, replication at the infection site, and activity against biofilm-embedded bacteria. This review highlights recent advances in phage therapy for OAIs, focusing on administration routes (intravenous, intra-articular, topical, and oral) and on novel pharmaceutical delivery systems such as hydrogels, bone cements, microparticles, nanoparticles, and implant coatings. Preclinical and early clinical studies have analyzed phage stability, controlled release, and the synergistic effects of combined phage/antibiotic therapy. However, challenges remain regarding standardization, immunogenicity, and regulatory approval. Nonetheless, phage therapy shows promise for clinical translation as an adjunct or alternative to conventional treatments for OAIs. Well-designed clinical trials are urgently needed to confirm the efficacy of phage therapy, optimize delivery strategies, and integrate the treatments in routine practice. Despite encouraging outcomes for a successful clinical implementation, regulation and standardization of GMP production are required. Full article

Background/Objectives: The aim of this study is to present our conformational approach to CAD/CAM planning and reconstruction of head and neck cancer defects using a single-barrel fibula free flap, where the right oral rehabilitation position and the best aesthetic recontouring are achieved through 3D conformational miniplates (3D-CMP). Methods: We retrospectively enrolled patients between 2024 and 2019 who underwent maxillo-mandibular cancer resection, reconstructed with single-barrel fibula free flap and 3D-CMP. All the suitable patients had a deferred procedure for implant rehabilitation. Microvascular and implant-related complications were recorded over a medium follow-up of 29 months. Results: Twenty-two patients were treated by demolitive and reconstructive microsurgery with 3D-CMP. Minor complications were reported in five patients. Successful flap positioning for dental rehabilitation was observed in all 16 patients. An analysis of 3D planning models and 3D post-surgery models reported a high level of accuracy. Conclusions: Our conformational approach, which matches a single-barrel fibula free flap with 3D-CMP, has proven to be effective in restoring aesthetics and function in our patient cohort. This approach could lead the FFF to become the gold standard for head and neck bone reconstruction compared to other bone flaps, overcoming all the limitations noted to date. Full article

Objectives: The middle cranial fossa (MCF) approach is valued for preserving hearing while accessing the internal auditory canal (IAC), petrous apex, inner ear, and related structures. This study evaluated its clinical outcomes across otolaryngological diseases, focusing on postoperative complications, hearing preservation, and the effect of IAC manipulation on auditory function. Methods: We retrospectively analyzed 35 patients who underwent MCF otologic surgery at a single center over twelve years. We calculated the proportion of MCF cases among all otologic surgeries and assessed postoperative complications and hearing changes (bone conduction thresholds). Outcomes were compared between patients with and without IAC manipulation. Results: MCF procedures comprised 1.4% of all otologic surgeries. Petrous bone cholesteatoma was the leading indication (15 cases). Intracranial complications occurred in 4 patients (11.4%): seizures, epidural abscess, and cerebral infarction. Facial nerve paralysis occurred in 3 (10.7%) patients without any cerebrospinal fluid leaks. In patients without IAC manipulation, hearing functions were preserved (22.3 ± 7.8 dB HL pre- vs. 25.7 ± 9.5 dB HL postoperatively), whereas those with IAC manipulation showed significantly greater deterioration. Conclusions: The middle cranial fossa approach, though technically demanding and infrequently used, offers a safe and effective option across various otolaryngological diseases. This approach achieved favorable hearing preservation with a low complication rate, particularly when intradural manipulation of the IAC was not required. Full article

Background/Objectives: Tumor-induced osteomalacia (TIO) is a rare acquired paraneoplastic syndrome caused by phosphaturic mesenchymal tumors (PMTs). FGF23, which is overproduced by PMTs, causes hypophosphatemia and osteomalacia, ultimately leading to multiple insufficiency fractures, which are the cause of TIO symptoms. Therefore, recovery from TIO symptoms often takes several months. Due to its paracrine effects, even minuscule amounts of residual PMT can cause treatment to fail. To further compound this, the most confident methods for residual PMTs, serum FGF23 level and ⁶⁸Ga DOTA-based PET/CT, are not readily available. For these reasons, there is currently no established method for early prediction of TIO treatment outcomes after surgery. This study focuses on mineral metabolism and bone turnover markers to identify a clinically practical and readily available biomarker that can predict TIO treatment outcomes. Methods: During treatment, we analyzed repeated measurements during treatment of mineral metabolism and bone turnover markers for 19 cases of TIO—Ca, inorganic phosphate (Pi), parathyroid hormone (PTH), 25-hydroxyvitamin D, alkaline phosphatase, Procollagen 1 N-terminal Polypeptide, and β-CrossLaps—in relation to treatment outcomes. We selected predictive marker candidates from among these markers by analyzing their patterns of change during treatment based on three viewpoints—association with (1) cure status, (2) time after treatment, and (3) the interaction effects between (1) and (2) using Linear Mixed Model analysis. We also validated the predictive performance of the selected candidates. Results: In long-term follow-up, only serum Pi and PTH levels were significantly associated with all three metrics mentioned above, suggesting that their patterns of change reflect the clinical course and results of TIO treatment. Pi was the only marker that displayed the same associations during short-term follow-up (two weeks and six weeks after treatment), suggesting that it is a rapidly responsive marker. The serum Pi level two weeks after treatment (Odds Ratio = 7.314, p = 0.028, AUC value of 0.907) and the normalization of Pi at two weeks post-treatment (Relative Risk = 9.975, p = 0.010; sensitivity = 100.0% [95% Confidence Interval (CI) 0.860 to 1.000], specificity = 60.0% [95% CI, 0.208 to 0.600]) were both significantly associated with a complete cure. Conclusions: Serum Pi is a fast, simple, and highly sensitive marker that can replace serum FGF23 and ⁶⁸Ga DOTA-based PET/CT in clinical practice for predicting a complete cure of TIO within two weeks of surgery.
