The shoulder stop is the most common surgical technique in France for stabilizing a shoulder with dislocations. It allows to realize an external lock of the joint.

Principle of a shoulder stop

The principle of a shoulder stop is to take the coracoid process which is attached to a tendon and a ligament, to sharpen the bony faces and to screw on the anterior edge of the glenoid of the scapula.

'The choice of a surgical technique however depends on each patient (symptoms, duration evolution, number of dislocation, type of sport, age ...) and the experience of the surgeon. A stop is feasible in almost all patients »
  • Phase 1: the sampling

    Part of the coracoid process is detached from the coraco-biceps joint tendon (common insertion of the short portion of the biceps and coracobrachial tendon).

  • Phase 2: the transfer

    Opening in two of the subscapularis muscle (and its tendon) to transfer the coracoid to the glenoid of the scapula.

    Avoids bone surfaces to facilitate fusion or consolidation.

  • Phase 3: screwing

    The coracoid is fragment is screwed on the glene of the scapula taking care that it is not overflowing (not to conflict with the humeral head during the movements of the shoulder).



Several effects are observed following a surgical operation of shoulder stop:

A bone abutment effect Increase the diameter of the glenoid and creates an anti-dislocation edge. The coracoid consolidates with the glenoid to form only one bone.
A tendon-muscular 'hammock' effect Hammock effect by transfer of the coraco-biceps joint tendon inserted the coracoid bone fragment across the subscapularis open in two through a 'split' By far the most effective because some unconsolidated stops work because of the healing of these tendons between them.


Many variants exist, with two screws, a screw, no screws (coracoplasty) bone fragment lying down or standing, repair of the capsule on the stopper etc … The whole is together under the term ‘stop’.

This is an operation usually open, we realize it now (Dr. Kany, Dr. Guinand and Dr. Croutzet) under arthroscopy in a minimally invasive way.
