Article Abstract
Background/aim: Heterotopic ossification (HO) is a common complication following total hip arthroplasty. Various prophylactic treatments have been proposed, including radiotherapy (RT). This review summarizes the evidence from meta-analyses on the efficacy of RT in preventing hip HO.
Materials And Methods: A literature search was conducted on PubMed. The quality of the meta-analyses was assessed using the AMSTAR-2 tool.
Results: Seven meta-analyses were included. One meta-analysis reported a significant reduction in HO occurrence after RT compared to the control group. Comparing RT and non-steroidal anti-inflammatory drugs, one and two meta-analyses showed significantly greater efficacy of RT in preventing severe HO and better outcomes in patients receiving drugs, respectively. Regarding RT settings, the postoperative and preoperative RT were each supported by one meta-analysis. Furthermore, two meta-analyses showed an advantage of multi-fractionated RT over single fraction RT. The overall confidence rate of the meta-analyses was moderate, low, and critically low in one, three, and three meta-analyses, respectively.
Conclusion: RT is a confirmed prophylactic intervention for HO. However, the precise optimization of timing, dosage, and fractionation requires elucidation. Future research should focus on the development of predictive models through large-scale data collection and advanced analytics to refine individualized treatment strategies and assess RT comparative effectiveness with drugs.

Purpose: To compare the long-term clinical outcomes and radiographic findings between hybrid surgery (HS) and anterior cervical discectomy and fusion (ACDF) for three-level cervical degenerative disc disease (CDDD). And the incidence, prognosis, and potential risk factors of heterotopic ossification (HO) more than 10 years after Bryan prosthesis replacement in HS has been explored.
Methods: From January 2007 to December 2014, a total of 46 patients who underwent either HS (n = 26) or ACDF (n = 20) for consecutive three-level CDDD were retrospectively analyzed.

Background: Heterotopic ossification (HO) is a common complication following hip arthroplasty that can limit hip range of motion (ROM). Oral direct factor Xa (FXa) inhibitors are commonly used anticoagulants after arthroplasty; however, they have a high risk of local bleeding and hematoma formation, which are significant triggers for HO formation. To our knowledge, there is no evidence regarding whether FXa inhibitors will increase HO incidence following hip arthroplasty.

Introduction: Complex proximal ulna fractures (including comminuted olecranon fractures and fracture-dislocations of the elbow) pose challenging management due to concomitant injuries to key stabilizers (radial head, coronoid process, and collateral ligaments). This study evaluates functional and radiographic outcomes following surgical treatment and explores the prognostic value of associated injuries, age stratification, and a new coronoid-centric classification system.
Methods: We retrospectively reviewed 43 patients with complex proximal ulna fractures treated between 2019 and 2024, with a minimum of 12 months follow-up (mean, 28 months).

Hip arthroscopy has become an increasingly common and effective surgical technique for the diagnosis and treatment of various intra-articular hip disorders. While generally considered safe and minimally invasive, the procedure is not without risks. The increasing volume and complexity of hip arthroscopies has led to a rise in reported complications, highlighting the importance of understanding potential adverse events and their management.
