Abstract:
Objective To explore the results of surgical treatment for disp la ced intra-articular glenoid fractures. Methods From June 1997 to June 2002, 19 p atients with more than 5 mms displaced glenoid fractures were open reduced and internally fixed. All fractures were classified according to Ideberg system, ty pe-Ⅰ fractures in 8 cases, Type-Ⅱ in 2, Type-Ⅲ in 3, Type-Ⅳ in 2, and Type-Ⅴ in 4 were retrospectively analyzed. The incidence of associated injuries was 78.9%(15/19). According to their patterns, fractures were exposed through poste rior approach (11 cases), anterior approach (6 cases) and posterosuperior approa ch (2 cases) and fixed with reconstruction plates and lag screws after satisfyin g reduction. Results All patients were followed up for an average of 17.5 months . According to Constant and Murley score, the median score was 93(range 11-100, mean 81). Fractures were manipulated under direct vision and anatomical reductio n was accomplished in 16 fractures. The radiographs showed a residual displaceme nt of more than 2 mm in 3 fractures after operation. The post-traumatic shoulder arthritis was found in 2 cases and the glenohumeral joint instability in 1 case . Conclusion To glenoid rim fractures combined humeral head subluxation, more th an 3-5 mm step-off displaced intra-articular fractures, and superior shoulder su spensory complex injury associated with glenoid fractures, early surgical interv ention is required to restore shoulder joint functions. The prognosis of glenoid fractures is determined by multiple factors such as associated injuries, qualit y of fracture reduction and surgical complications.
