One of the most common complications associated with a diaphyseal humeral fracture is the development of a radial nerve injury. We conducted a study to analyze the degree of recovery and prognostic factors associated with radial nerve palsy in patients with diaphyseal humerus fractures. We retrospectively analyzed 28 patients who presented to the Hospital La Fe, Valencia, Spain, with a diaphyseal humerus fracture associated with radial nerve injury between 2010 and 2020. A total of 14.3% (n = 4) of the patients in our cohort had open fractures and 85.7% (n = 24) had closed fractures. There were no statistically significant differences between the type of treatment and the type of fracture (p = .13). There were also no significant differences between the type of treatment and recovery time (p = .42). There was a statistically significant difference (p = .04) in the mean recovery time for patients with preoperative radial nerve injuries (11.9 months) compared with patients who sustained a radial nerve injury secondary to surgical repair of the fracture (8.6 months). The difference in recovery time between patients with open and closed fractures was not statistically significant (p = .3). Results of the study showed that the type of fracture (i.e., open or closed) did not affect radial nerve palsy recovery time. Patients who sustain radial nerve injuries secondary to a surgical repair have a shorter recovery time than patients who sustain primary radial nerve injuries.

Introduction: The treatment of tibial plateau fractures is a challenge in the elderly population due to osteoporosis and associated comorbidities. The choice between open reduction and internal fixation (ORIF) and total knee replacement (TKR) is controversial. The aim of this study is to compare functional outcomes between TKR and ORIF in elderly patients with tibial plateau fractures. Materials and Methods: A retrospective observational study was conducted on 27 elderly patients with Schatzker type II, III, or IV tibial plateau fractures treated between January 2018 and December 2022, with prior history of osteoporosis or gonarthrosis. 14 patients underwent treatment with TKR, while 15 patients underwent ORIF. Demographic data, pre-operative characteristics, surgical details, post-operative evolution, and functional outcomes were collected and analyzed. Results: The TKR group consisted mostly of women (92.9%) with a mean age of 76 years, while the ORIF group had a mean age of 68 years. Both groups had similar comorbidity profiles. No significant differences were observed in the mean surgical time (P = 0.18). Significant differences were found between the knee society score (KSS) knee score for total knee arthroplasty (TKA) and ORIF (P = 0.01) and in the KSS function score, with better functional values in the TKA group compared to the ORIF group (P = 0.034). No significant differences were observed in the probability of complications regardless of whether the patients underwent TKA or ORIF (P = 0.6). Conclusion: Treatment of tibial plateau fractures with TKR achieves superior functional outcomes and lower complication rates compared to open reduction and internal fixation in elderly patients. Keywords: Tibial plateau fractures, total knee replacement, orteoarthritis, osteoporosis.

Objective The objective of this study was to perform an epidemiological analysis of patients presented to the Musculoskeletal Tumors Committee of a reference hospital. Material and method A retrospective analysis of patients with sarcomas treated in a reference Sarcoma Unit between 2009 and 2022 was carried out. Results A total of 1978 patients were analyzed, of which 1477 (74.67%) were diagnosed as sarcomas. They were divided into 446 (30.20%) bone tumors and 1.031 (69.80%) soft tissue tumors. The most common benign bone tumor was enchondroma (27.23%), giant cell tumor (59.21%) was the most common tumor of intermediate malignancy and the malignant one was osteosarcoma (24.78%). The most frequently observed benign soft tissue tumor was lipoma (50.74%), the atypical lipomatous tumor (53.25%) was the most frequent tumor of intermediate malignancy and the malignant one was sarcoma of uncertain differentiation (38.10%). Conclusion Our study represents the first work on the epidemiology of sarcomas and other musculoskeletal tumors in our country, being very useful to adapt the resources destined for their diagnosis and treatment.
