Abstract
We have treated several patients who complained of posterior voluntary subluxation of the shoulder. The purpose of this study was to report the outcome of these patients treated with a capsulorrhaphy and bone block.
Three men in their twenties have been followed-up for more than two years since our surgical treatment. One nineteen-year-old woman was just operated on recently. A new posterior approach between the deltoid and triceps lateral head with the arm elevated more than 100 degrees at nearly zero position was selected. This posterior approach to the shoulder is a new one, which we could not find in any textbook. We have tried this approach seven times and have not experienced any damage to either the deltoid muscle or the axillary nerve. This approach is much easier than the deltoid splitting one.
All the patients now have no subluxations, but one patient still complains of slight motion pain and dysfunction of the arm. They were evaluated by the J.O. A. Shoulder Score. The final total scores were 95 95 95 and 82. All the patients are satisfied with our surgical treatment.
We conclude that this new approach is a reasonable way to operate a posterior aspect of the shoulder, especially after an arthroscopy. Our choice to treat these posterior voluntaty subluxation patients of the shoulder with a capsulorrhaphy and bone block seems to be appropriate, now.
