いわゆる動揺性肩関節に対するglenoidosteotomyの検討

抄録

Over the years, loose shoulder syndrome has been treated by several procedures. Between 1978 and 1985,30 patients with 32 shoulders involved were treated by glenoid osteotomy. Their ages ranged from 14 to 33 years with an average of 22.1 years. Patients were usualy disabled by pain in activity. Instability of the shoulder joint was a common feature in all. The results were evaluated after an average length of follow-up of 6.4 years. In every instance, X-ray confirmation of instability was demonstrated with the arm elevated, and the degree of slipping of the humeral head beyond the glenoid was measured both preoperatively and postoperatively. Clinical findings showed good results in twenty-three cases (77 percent) with displasia of the posterior margin of the glenoid.
Seven cases (23 percent) with general joint laxity showed poor results.
Postoperatively X-ray examination showed effectively the control of the tendency to slip by the bony reconstitution of the posterior-inferior margin of the glenoid in all.
Glenoid osteotomy for loose shoulder should be done for patients with dy splasia of the posterior-inferior glenoid found by X-ray in A-P view and with the arm elevated on axillary view.
