Midterm outcome of superior capsular reconstruction using doubled acellular human dermal allograft for irreparable rotator cuff tear.

BACKGROUND: Thicker (folded) facia lata autografts have been shown to be superior to thinner grafts and single-layered acellular human dermal (HD) allografts for superior capsular reconstruction (SCR) in biomechanical studies. The aim of this study was to evaluate the midterm clinical outcomes following SCR for irreparable supraspinatus tears using doubled (folded) HD allograft. METHODS: Thirty-two patients who had undergone SCR using doubled HD allograft between February 2012 and January 2020 were recruited in a continuous manner in this retrospective study. The inclusion criteria were SCR performed for irreparable supraspinatus tear and a minimum of 2 years' follow-up. The primary outcome measure was the American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES) score. The secondary outcome measures were complications and revision surgery. A subgroup analysis was performed between patients who received a "standard" graft of mean 3-mm thickness or a "thick" graft of mean 4.4-mm thickness. RESULTS: One patient was lost to follow-up. A total of 31 patients (31 shoulder joints) were analyzed with a mean follow-up duration of 48 months (range, 25-96 months). Following surgery, there was significant improvement in the ASES score from 18.1 ± 14.3 (preoperative) to 76.3 ± 25.1 (postoperative) (P < .001), with a satisfactory clinical outcome obtained in 83.8% of the patients. In a subset of 8 patients completing 5 years' follow-up, the clinical improvements were sustained. The percentage of patients with a clinically successful outcome was higher among those with thick grafts compared to those with standard grafts, although this failed to reach statistical significance (94.4% vs. 69.2%, risk ratio 1.36, 95% confidence interval 0.93-1.99, P = .13). One patient within the standard group underwent revision surgery. CONCLUSION: SCR for irreparable rotator cuff tears with doubled HD allograft results in improved clinical outcomes and low reoperation at midterm follow-up duration.

Fibula Nail Outcomes in Soft Tissue Compromised Ankle Fractures.

BACKGROUND: To determine the clinical outcomes following fibula nail fixation and to identify the indication for the use of fibula nails in lower limb fractures. METHODS: Retrospective study of adult patients from 2 major trauma centers (MTCs) and 9 trauma units (TUs) who underwent fibula nail fixation for AO/OTA 44 fractures between January 1, 2018, and October 31, 2020. Outcome measures included infection, metalwork complications, nonunion or malunion, time to union, and length of inpatient hospital stay. RESULTS: Ninety-five patients were included, with a mean age of 66 years; 57.9% of patients were female. The average body mass index was 30. Sixty-nine patients (72.6%) sustained a Weber B and 24 (27.4%) sustained a Weber C fracture. In addition, 26.3% were open fractures and all patients had soft tissue compromise affecting the lateral malleolus. The calculated infection rate for fibula nail was 4.2% and metalwork complication rate was 5.2%. The nonunion and malunion rate was 8.4% and rate of removal of hardware was 2.1%. The average time to union was 12.5 weeks, and length of inpatient stay was 9.4 days (SD 10). CONCLUSION: This multicenter study demonstrates that use of a fibula nail appears to be a safe approach to treating patients who have a physiologically higher risk of surgery, poor skin condition, and a complex fracture pattern. LEVEL OF EVIDENCE: Level III, case-control study.
