نبذة مختصرة : Introduction The optimal treatment approach for Bony Bankart remains a subject of considerable debate among shoulder surgeons. Existing literature highlights low recurrence rates and high patient satisfaction with nonoperative treatment, particularly in the middle-aged population. This study aimed to evaluate the recurrence rate of dislocation, as well as the clinical and functional outcomes in middle-aged individuals treated nonoperatively following an acute bony Bankart fracture. Additionally, the impact of glenoid rim size and fragmentation on the treatment outcome was investigated. Material and methods A prospective analysis was conducted on 20 patients aged over 50 with nonoperatively treated bony Bankart fractures, ensuring a minimum follow-up of 24 months. The study population was categorized based on fragment size (small and medium) according to Kim classification and glenoid rim fragmentation (type 1b and 1c) according to Scheibel classification. Data including UCLA score, Rowe score, recurrence rate, clinical instability, and range of motion (ROM) were collected and analyzed. Results The average UCLA and Rowe scores were 32.15 ± 2.85 and 93.85 ± 2.19, respectively, with no instances of dislocation recurrence. The affected shoulder exhibited no significant reductions in ROM compared to the contralateral side, except for a loss of external rotation (ER) (13.08° ± 7.51; p = 0.005). No differences were observed based on fragment size, although patients with multifragmented glenoid rims showed a greater loss of ER compared to those with a solitary fragment, albeit not reaching statistical significance. Conclusion Nonoperative treatment appears to be a viable and effective option for middle-aged individuals with bony Bankart fractures, resulting in favorable functional outcomes and a low risk of recurrence. Additionally, a notable loss of external rotation was observed in fractures with glenoid rim fragmentation. Level of evidence IV.
