The Effects of Different Surgical Stabilization Methods in Recurrent Anterior Shoulder Instability

Shoulder instability is the inability to retain the humeral head in the glenoid fossa. The incidence of instability is 8.2 to 23.9 per 100,000 person-years with an estimated prevalence of 1.7%. The most common shoulder instability with a rate of 98% is anterior dislocation, in which the humeral head is displaced anterior to the glenoid. Conservative and surgical treatments of instability are available. There are many controversial issues related to these methods in the literature. For example; an atrophy and functional loss in the infraspinatus after reimplissage, atrophy and loss of proprioception in the muscles around the shoulder after capsular repair, and loss of proprioception after the laterjet procedure have been reported.Therefore, the aim of this study was to compare different surgical stabilization methods in terms of pain, proprioceptive sensation, functional status and muscle activation in recurrent anterior shoulder instability, which is very common in adults.
