Abstract
Background
The open Latarjet procedure is widely used for the treatment of recurrent anterior shoulder instability associated with bipolar bone defects. Preoperative imaging parameters may be associated with short-term functional outcomes following the open Latarjet procedure for recurrent anterior shoulder instability. Materials and Methods: This retrospective study included 16 patients treated with the modified open Latarjet procedure. Preoperative CT or MRI measurements included glenoid bone loss, Hill–Sachs interval (HSI), glenoid track (GT), HSI/GT ratio and glenoid index. At 6 months, patients were evaluated using the auto-Rowe and auto-Walch–Duplay scores, range of motion, recovery time, residual symptoms, and return to activity.
Results
The median Rowe and Walch–Duplay scores were 95 (90–95) and 75 (70–90), respectively. Fifteen patients resumed physical activity, including seven who returned to their previous level. No procedure-related complications were reported. Among the imaging parameters analysed, a higher HSI/GT ratio was associated with lower Walch–Duplay (p = 0.007, q = 0.043) and Rowe scores (p = 0.014, q = 0.043). Higher glenoid bone loss was associated with a lower Rowe score (p = 0.015, q = 0.043), while a higher glenoid index was associated with a lower Walch–Duplay score (p = 0.017, q = 0.043). Glenoid track showed a positive nominal association with the Walch–Duplay score (p = 0.036), which did not remain significant after FDR adjustment (q = 0.072).
