肩関節脱臼骨折に対する鏡視下バンカート手術の治療経験

抄録

We report three cases of anterior shoulder dislocation including anterior glenoid rim facture treated by arthroscopic Bankart repair. The patients were two men and one woman with a mean age of 46 years (range, 24 to 61 yr). The mean standby period from injury to surgery was 14.7 days, and the mean follow-up period after surgery was 4.7 months. The fractured glenoid rim bones were attached to the anteroinferior glenohumeral ligament. The displaced fragments were repositioned anatomically and directly through the fragment to the glenoid rim with suturing of its ligament. Suture fixation was performed by the dual suture method with biodegradable anchors. One case required a simultaneous arthroscopic rotator cuff repair. CT examination confirmed bone union in all cases, and no recurrence of the shoulder dislocations was observed. An excellent range of shoulder motion was obtained in the short-term follow-up period. The mean Japanese Orthopaedic Association (JOA) shoulder score was 91 points. The modified arthroscopic Bankart repair gave good clinical results for anterior glenoid rim fracture.
