Predictive value of implant removal time and acromion-hook angle on subacromial osteolysis following hook plate fixation for acromioclavicular dislocation.

Background: Subacromial osteolysis is a typical complication following hook plate fixation for acromioclavicular (AC) dislocation. Many factors can affect the occurrence and progression of subacromial osteolysis (SAO). The objective of this study was to investigate the predictive value of the implant removal time and acromion-hook angle for subacromial osteolysis following hook plate fixation for AC dislocation.

Subacromial osteolysis following hook plate fixation for acromioclavicular dislocation: a systematic review and meta-analysis.

Background: Clavicular hook plates are extensively used in the treatment of acromioclavicular dislocation. Subacromial osteolysis is a typical complication following hook plate fixation. We performed a systematic review and meta-analysis to determine the incidence of subacromial osteolysis and analyzed the associated characteristics of subacromial osteolysis to guide surgeons.
