Background: Pigmented villonodular synovitis (PVNS), also known as tenosynovial giant cell tumor, is a rare proliferative disorder of the synovial membrane that primarily affects the knee joint. Despite advances in imaging and surgical techniques, diagnosis is often delayed, and optimal treatment remains debated. Methods: A Narrative review was conducted according to PRISMA guidelines using PubMed, MEDLINE, and Scopus databases from January 2000 to December 2024. Studies reporting on epidemiology, clinical features, imaging, treatment, and outcomes of PVNS were included. Results: Sixty-six studies encompassing 120 patients were included. The majority of cases were diffuse PVNS. MRI was the most effective imaging tool. Arthroscopic synovectomy was the most common treatment, though recurrence rates remained high, particularly in diffuse forms. Adjuvant treatments, including radiosynoviorthesis and biologic therapies such as infliximab or pexidartinib, were employed in recurrent or unresectable cases. Conclusions: Early diagnosis and complete surgical excision remain the mainstay of treatment. Combined open and arthroscopic approaches are recommended in diffuse PVNS. Further prospective studies are needed to define optimal long-term management.

Bone tumors of the upper limb are a common cause of bone pain and pathological fractures in both old and young populations. Surgical reconstruction and limb salvage have become valid options for these patients despite this kind of surgery being challenging due to the need for wide bone resection and the involvement of surrounding soft tissues. Computer-assisted technology helps the surgeon in pre-operative planning and in designing customized implants. The aim of this study was to investigate the surgical outcomes and complications of custom-made prostheses in oncologic reconstruction of the upper limb and if they are reliable options for patients suffering from aggressive tumors. An electronic search on PubMed, Google Scholar, and Web of Knowledge was conducted to identify all available articles on the use of custom-made prostheses in oncological resections of the upper limb. Twenty-one studies were included in the review, comprising a total of 145 patients with a mean age of 33.68 years. The bone involved was the humerus in 93 patients, and the radius was involved in 36 patients. There were only six cases involving proximal ulna, three cases involving the scapula, and seven cases involving the elbow as well as soft tissues around it. The most frequent primary tumor was the giant cell tumor, with 36 cases, followed by osteosarcoma with 25 cases, Ewing Sarcoma with 17 cases, and Chondrosarcoma with 7 total cases. Forty patients were affected by bone metastases (such as renal cell cancer, breast cancer, melanoma, and rectal cancer) or hematologic diseases involving bone (lymphoma, myeloma, or non-Hodgkin disease). Custom-made prostheses are a viable option for patients who suffer from malignant tumors in their upper limbs. They are a reliable aid for surgeons in cases of extensive resections.

Background: The management of infections involving the distal tibia and ankle is a significant challenge in orthopedic surgery due to complex anatomy and the high risk of complications. The study aims to present our clinical experience in managing these infections and focusing on surgical strategies, infection control, and functional outcomes over a minimum 24-month follow-up period. Methods: This is an observational, retrospective case series of 17 patients treated for osteoarticular infections of the distal tibia and/or ankle between January 2020 and May 2023, in a second-level referral trauma center. A staged surgical approach was employed, including radical debridement, temporary stabilization with external fixation, and, in most cases, implantation of a cement spacer loaded with antibiotics. Functional outcomes were assessed using scores such as EQ-5D-5L. Results: The cohort was predominantly male (76.5%), with a high prevalence of elevated BMI and comorbidities. Infection onset was most frequently associated with open fractures (64.7%). Staphylococcus aureus was the most common isolated pathogen (41.2%), and infections caused by Gram-negative or multidrug-resistant bacteria were associated with more reoperations. Overall, complications occurred in 10 patients (58.8%), requiring reintervention in 9 patients (52.9%). Limb salvage was achieved in 16 of 17 patients (94.1%). Conclusions: Our study highlights the critical role of a tailored, multidisciplinary approach in managing these complex infections. Meticulous surgical planning and proactive management of complications are essential for optimizing patient outcomes.

Introduction: Proximal femoral fractures (PFF) are a significant health concern among the elderly, often leading to complications and high mortality rates. Intramedullary nailing is widely considered the most effective treatment for lateral proximal femoral fractures (LPFF), with the Tip Apex Distance (TAD) being a crucial predictor of surgical success. This study aimed to compare outcomes between patients treated with and without the ADAPT (ADAptive Positioning Technology) system, which aids in the precise placement of the cephalic screw. Materials and Methods: A retrospective analysis was conducted on 97 patients with intertrochanteric fractures treated in 2022. Patients were divided into two groups: those treated with the ADAPT system (group I, n=34) and those treated without it (group II, n=63). Fractures were classified according to AO/OTA classification. The primary outcomes measured were operative time, cephalic screw angle, TAD, and incidence of lag screw cut-out. Statistical analyses included chi-square tests and t-tests, with significance set at P < 0.05. Results: The ADAPT system did not significantly reduce TAD (18.21 mm in the ADAPT group vs. 19.94 mm in the control group, p=0.149). Operative times were similar between the groups. The incidence of lag screw cut-out was low in both groups, with no significant differences. The study confirmed a strong correlation between higher TAD and increased risk of screw cut-out, underscoring the importance of precise screw placement. Discussion: Computer-assisted surgery, such as the ADAPT system, aims to enhance the accuracy of cephalic screw placement. In this study, the ADAPT system didn’t demonstrate a statistically significant advantage in reducing TAD or preventing screw cut-out. Nevertheless, the critical role of TAD in preventing fixation failure was reaffirmed, emphasising the need for precise surgical techniques. Conclusion: While the ADAPT system did not show a significant advantage in reducing TAD or preventing screw cut-out in this study, the importance of achieving optimal TAD in cephalomedullary nailing was reinforced. Future research should continue to explore the role of computer-assisted systems in enhancing surgical accuracy and improving outcomes for patients with LPFF.

Introduction: The elbow is a rare site for bone tumors, and for this reason, the literature provides little data on the epidemiology of metastatic lesions involving the distal humerus, proximal ulna, and radius. Before performing surgery of the metastatic bone, it is first necessary to consider both patients’ and metastatic lesions’ features in order to better choose the best possible treatment. This systematic review aims to collect data on elbow metastases, delineate primary tumors leading to such metastases, guide surgical treatment decisions, and evaluate reconstructive techniques and associated complications. Material and Methods: A systematic literature review was conducted in April 2024, searching the PubMed, MEDLINE, and Cochrane Library databases using specific search terms related to elbow metastases. The Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) was followed. Eligible studies reported at least one patient with metastatic bone disease involving the elbow region and specified the undertaken treatment. For studies reporting multiple skeletal sites, only elbow-specific data were extracted. We excluded recurrences of primary elbow tumors. The methodological quality of included studies was assessed with the modified Coleman Methodology Score (mCMS). Results: In total, 28 articles (103 patients) were included. The studies were predominantly case reports (68%), with a mean mCMS of 31. Gender was reported for only 41 patients: 71% were male and 29% female. The mean age at diagnosis of elbow metastatic lesion was 55 years old. Renal cell carcinoma was the most common primary tumor (28%), followed by breast (9%) and lung cancer (6%). The distal humerus was the most frequently affected site (85%). A surgical approach was adopted in 90% of cases, whereas 10% of patients were managed conservatively. Forty-five patients underwent wide tumor resection followed by reconstructive surgery while forty-eight patients received a surgical treatment for either pathological fractures or impending fractures. Conclusions: When treating elbow metastasis, a thorough evaluation of the patient is crucial, considering the patient’s functional status, pain management needs, and overall prognosis; all these features influence the treatment of choice. The selected treatment should aim to provide optimal functional outcomes and minimize complications. For patients with pathological or impending fractures, single or double plate fixation is typically the preferred approach. For patients with severe, symptomatic lesions unresponsive to conservative therapy, resection followed by the implantation of a modular prosthesis usually offers the best clinical and functional outcomes.

Purpose: Ankle fractures represent a significant health concern for athletes, comprising 15%–25% of all sports‐related injuries. With increasing sports participation across all age groups, the public health impact of these injuries is expected to grow. Open reduction and internal fixation (ORIF) is a common approach to managing ankle fractures, particularly for athletes requiring rapid return to sports. However current information on the return to sports post‐injury is largely anecdotal. Methods: A comprehensive literature search was conducted using keywords related to ankle fractures and sports return. Databases searched included Medline (PubMED), Cochrane and Google Scholar up to 12 April 2024. Articles published in English, Spanish, French, Portuguese, and Italian were considered. A total of 17 studies involving 1422 patients were analysed. Inclusion criteria covered randomised controlled trials and case series of over 10 patients focused on athletes with closed ankle fractures. Studies on paediatric fractures, soft tissue injuries, and non‐sports‐related fractures were excluded. Results: The review analysed various types of ankle fractures, with an average patient age of 31.4 years. ORIF was the predominant treatment (89.4%), and the average return‐to‐sport rate was 87.1%. Time to return varied, with an average of 134.5 days. Recovery time was longer for more severe fractures, such as bimalleolar and trimalleolar fractures, which showed times of up to 720 days. Functional outcomes improved with early rehabilitation, and the average Foot and Ankle Outcome Score (FAOS) for sports was 85.6 after 12 months. Conclusion: Returning to sports after an ankle fracture is a critical concern for athletes. This systematic review provides valuable insights into the prognosis and timeline for resuming sports activities. By synthesising current evidence, it offers guidance for clinicians and athletes on managing recovery and optimising return to sports. Standardised, high‐quality studies are needed to provide clearer guidelines. Level of Evidence: Level III. For Clinical Trials: PROSPERO registration number 594839.
