We describe two cases of recurrence of unaffected shoulder dislocation and any other joint compensative dislocation following operation for atraumatic shoulder instability.
The first case was a 16 year-old woman. She sustained dislocation of the shoulder and was misdiagnosed as having recurrent dislocation of the shoulder by her previous doctor, and an arthroscopic shrinkage and two capsular shifts were performed for each shoulder. However recurrence developed, and she came to our hospital. Although glenoidplasty was performed for each shoulder, recurrence occurred. Therefore major pectoral muscle transfer was performed. No recurrent dislocation occurred. However, her fingers presented swan neck deformity. The second case was a 22 year-old woman. She dislocated her right shoulder habitually and glenoidplasty was performed. Recurrence developed one year later. Therefore arthroscopic thermal shrinkage was performed. Four months later, recurrence was seen and bilateral sternoclavicular joints and the left elbow were dislocated habitually. Her left shoulder changed to habitual dislocation. Recurrence of the shoulder dislocation of shoulders operated on for severe atraumatic shoulder instability presented more than a little, despite an exact diagnosis and surgery. We reported not only recurrence but dislocation of the unaffected shoulder or other joints. Sustained dislocation of the shoulder is a very rare dislocation. Keiser reported a woman who could not sustain the reduced position. Kuroda described two cases of sustained anterior subluxation of the shoulder. Though Keiser mentioned the possible implication of psychological factors, Kuroda said they were not indispensable. When doing surgery for atraumatic shoulder instability, you are required to pay attention to other joint dislocation secondarily.
