Because the older operations of capsulorrhaphy and Clairmont's muscle sling procedure for recurrent dislocation of the shoulder have not proved satisfactory, tenosuspensions have become a welcome substitute. Of these, the Nicola1 procedure is likely to prove the best, because the operation, which consists of a suspension of the head of the humerus by passing the tendon of the long head of the biceps muscle through it, is sound anatomically and simple to perform. The modification herein suggested is designed to facilitate conducting the tendon through a newly formed channel in the head of the humerus and also to insure a snug relationship between the two, which is one of the most important details in preventing recurrence of the dislocation.
To insure uniformly good results from this operation, certain technical details must be rigidly adhered to. These are as follows:
1. The channel through the head of the humerus must
