PREVALENCE OF LESIONS ASSOCIATED WITH TRAUMATIC RECURRENT SHOULDER DISLOCATION.

Objective: To evaluate the prevalence of lesions associated with traumatic anterior shoulder instability and the relationships between the prevalence of these lesions and the number of episodes and time since symptoms started.

Method: Fifty-seven patients aged 18 to 40 years, with traumatic anterior shoulder instability, more than one episode of shoulder dislocation and at least six months since the first dislocation, who required surgery to treat the instability, were selected. Arthroscopic inspection was performed on all the patients to assess any associated lesions.

Resection of the medial end of the clavicle: an anatomic study.

The biomechanical importance of the costoclavicular ligament is well known; however, an extensive debate still exists regarding the amount of the medial clavicle that can be removed without injuring the ligament. The goal of this anatomic study in fresh cadavers is to measure the distance between the inferior articular surface of the medial clavicle and the most medial clavicular insertion of the costoclavicular ligament, as well as to verify whether there is a relationship between this measurement and the length of the clavicle. Dissection of 100 shoulders from 50 fresh cadavers was performed.
