AI Article Synopsis
- - This study aimed to identify risk factors for complications related to bone-anchored hearing implant (BAHI) surgery by analyzing data from 581 adult patients between 1988 and 2007.
- - Key findings indicated that skin disease and profound learning difficulties significantly increased the likelihood of soft tissue reactions, while female gender showed a protective effect.
- - Additionally, smoking was identified as a significant risk factor for implant loss and was also associated with lower chances of needing revision surgery, suggesting that certain health conditions and behaviors may influence BAHI surgery outcomes.
Article Abstract
Objective: To identify risk factors for complications after bone-anchored hearing implant (BAHI) surgery.
Study Design: Retrospective cohort study.
Setting: Tertiary referral center.
Patients: All adult patients who received titanium bone-anchored hearing implants at our clinic between September 1, 1988 and December 31, 2007 were approached to fill out a questionnaire on comorbidity factors. A total of 581 patients with 669 implants were included in the analysis.
Main Outcome Measures: Implant loss, soft tissue reactions, and revision surgery after BAHI implantation.
Results: Skin disease and profound learning difficulties were risk factors for time to first soft tissue reaction, hazard rate ratio of 3.41 (95% CI 1.45-8.01) and 3.42 (1.03-11.39), respectively. Female gender showed a trend toward a negative risk for time to first soft tissue reaction, hazard rate ratio 0.60 (0.35-1.03). In multivariable analysis, skin disease and female gender were observed as independent associative factors, adjusted hazard ratio 3.08 (1.32-7.16) and 0.56 (0.33-0.94). For revision surgery, female gender and cardiovascular disease were identified as negative risk factors in univariable analysis, and smoking showed a trend toward a negative risk, with hazard ratios of 0.15 (0.07-0.32), 0.07 (0.03-0.20), and 0.51 (0.24-1.07), respectively. In multivariable analysis, smoking and female gender were observed as independent associative factors, adjusted hazard ratio 0.45 (0.22-0.95) and 0.14 (0.06-0.30). Smoking could be identified as a risk factor for implant loss with a hazard ratio of 3.32 (1.36-8.09).
Conclusion: Retrospective analysis of comorbidity factors and clinical outcomes revealed risk factors for postoperative complications after BAHI surgery.

Operation Room, Hunan University of Medicine General Hospital, No. 144, Jinxi South Road, Huaihua City, Hunan Province, 418000, China.
Objective: The surgical team in this study examined the efficacy of a modified reverse sural neurocutaneous flap repair in treating soft tissue defects of the ankle and foot caused by accidents.
Methods: This study enrolled 89 patients treated for soft tissue defects of the ankle or foot between January 2007 and December 2023. The patients were divided into two groups: 44 patients underwent a modified reverse sural neurocutaneous flap repair, while 45 received traditional treatment.
Open lower limb fracture reconstruction in the elderly population: the experience of a major trauma centre.

Department of Plastic and Reconstructive Surgery, Addenbrookes Hospital, Hills Rd, Cambridge, CB2 0QQ, UK.
Purpose: Management of the elderly patients presenting with open lower limb fractures is challenging due to physiological changes and pre-existing co-morbidities. The aim of this study was to assess the compliance with the British Orthopaedic Association's Standards for Trauma Number 4 (BOAST 4) guidelines in this patient group.
Methods: The study included a retrospective analysis of all the patients aged > 65 years old admitted with open lower limb fracture between 2017 and 2019 to a major trauma centre (MTC) in East of England.

Cross-sectional cardiac imaging plays an essential role in the evaluation of pediatric patients with congenital and acquired heart disease. While the focus of cardiac imaging is primarily on evaluating cardiac structures, it also provides valuable insights into extracardiac structures and associated abnormalities. The radiologists and cardiologists interpreting these exams play a critical role in recognizing these findings and providing recommendations for follow-up testing when indicated.

Lower limb biomechanics of chronic ankle instability (CAI) individuals has been widely investigated, but few have evaluated the internal foot mechanics in CAI. This study evaluated bone and soft tissue stress in CAI contrasted with copers and non-injured participants during a cutting task. Integrating scanned 3D foot shapes and free-form deformation, sixty-six personalized finite element foot models were developed.

Objectives: Paravertebral crystal deposition disease, characterized by the deposition of crystals around the vertebral bodies leading to acute inflammation and pain, is a condition that remains largely unrecognized. This study aims to elucidate the prevalence, clinical features, and CT findings associated with this disease.
Methods: We retrospectively analyzed 14,839 consecutive patients who underwent chest and/or abdominal CT (September 2017 to September 2024) owing to chest, abdominal, or back pain.
