Bilateral anterior glenohumeral dislocation in a weight lifter.

A case of bilateral anterior dislocation of the shoulder joint is described. The patient was a recreational weight lifter who sustained the injury while performing the 'pull-over' bench movement using free weights. Probably, the shoulders dislocated when the force developed by the periarticular muscles was less than the actual weight that the patient was trying to lift. The need for stricter safety rules and better supervision in health clubs is stressed.

The unstable shoulder in the adolescent athlete.

Shoulder dislocation and subluxation occur frequently in athletes, with peaks in the second and sixth decades. The majority of traumatic dislocations are in the anterior direction. The most frequent complication of shoulder dislocation is recurrence--a complication that occurs much more often in the adolescent population. The dynamic (muscular) and static (predominantly capsuloligamentous and labral) restraints to shoulder instability are now well defined. Recent surgical procedures for shoulder instability have become less interventional and have focused on restoring disrupted static restraints. The aim of rehabilitation is to enhance the dynamic muscular and proprioceptive restraints to shoulder instability.

Shoulder instability: management and rehabilitation.

Shoulder dislocation and subluxation occurs frequently in athletes with peaks in the second and sixth decades. The majority (98%) of traumatic dislocations are in the anterior direction. The most frequent complication of shoulder dislocation is recurrence, a complication that occurs much more frequently in the adolescent population. The static (predominantly capsuloligamentous and labral) and dynamic (neuromuscular) restraints to shoulder instability are now well defined. Rehabilitation aims to enhance the dynamic muscular and proprioceptive restraints to shoulder instability. This paper reviews the nonoperative treatment and the postoperative management of patients with various classifications of shoulder instability.

Bilateral luxatio erecta humeri.

The authors report one case of bilateral inferior dislocation of the shoulder, a rare form of injury, accounting for only 0.5% of all shoulder dislocations. Bilateral cases are even less frequent, with only six cases reported in the literature. The injury was complicated by paresia of the left axillary nerve and sensory alterations in both median nerves, without any associated osteoarticular or vascular injuries. The patients made a complete functional recovery within three years.

Body surfing as a cause of luxatio erecta: report of four cases.

True inferior dislocation of the shoulder (luxatio erecta) is a rare type of shoulder dislocation. It is caused by hyperabduction of the arm while in the overhead position. We report four recent cases, all of which occurred while body surfing. All of the individuals in this report were struck by a wave with their arms in the overhead position and their arms were forced into the sand.

Bristow-Latarjet procedure for recurrent anterior dislocation of the shoulder. A 2-5 year follow-up study on the results of 112 cases.

A follow-up study of 111 out of 112 patients operated on for shoulder joint dislocation according to the Bristow-Latarjet procedure during the years 1975 through 1979 in four Swedish hospitals is presented. The average follow-up time was 30 months (range 24-60 months). There were seven cases of significant recurrences (6 per cent). During follow-up, further surgery had been performed on four of these. Another eight patients (7 per cent) had experienced occasional insignificant subluxations. In one case neurolysis of the musculocutaneous nerve was undertaken because of postoperative paresis of elbow flexors. The average limitation of outward rotation as compared with the nonoperated side was 19 degrees in adduction and 21 degrees in abduction. There was a measurable difference in strength between the operated and nonoperated shoulders. The results were considered excellent or good by 101 of the patients (90 per cent), fair by eight and bad by three. Of 12 cases with failed surgery before the Bristow-Latarjet procedure 10 regarded the result as good or excellent.

[Significance of the limbus glenoidalis for the stability of the shoulder joint].

Besides the osseous structures and the muscular elements, the capsular and ligamentous apparatus, including the limbus genoidalis, is of utmost importance for the stability of the shoulder-joint. In the literature the limbus glenoidalis (L.G.) is generally described as a fibrocartilagineous structure comparable to the menisci of the knee-joint. Basically, the cause of a primary foreful shoulder-dislocation may be either a direct or an indirect trauma. The lesions during luxation concern the joint's capsula, the L.G. and the head of the humerus. However, in the literature one finds many different explanations as to which of those lesions is responsible for the subsequent development of recurring shoulder dislocation. The variability of concepts is reflected by the large number of operative procedures that are advised as treatment of a recurring dislocation. Assuming that the L.G. substantially contributes to the stability of the shoulder joint, we have investigated structure, blood-perfusion and anatomical connections of the L.G. The mechanism of the primary shoulder dislocation was simulated in mechanical strain-experiments, carried out on human corpse specimens. The occurring lesions were analysed. The following investigations were undertaken in alltogether 182 fresh specimens of human shoulder joints: measurement and calculation of the joint-surfaces of scapula and humeral head, dye-injection of the arteria axillaris, in order to demonstrate the vascular supply of the limbus glenoidalis, histological examination of the structure of the limbus glenoidalis, mechanical strain-experiments, that simulate the dislocation mechanism of the shoulder-joint. The calculations of joint-surfaces showed a relative decrease of the scapular joint-surface with growing age. The relation of the scapular joint-surface (always plus limbus glenoidalis) to the joint-surface of the humeral head is 1: 2.25 +/- 0.38 in men and 1: 2.20 +/- 0.11 in women (age-group: 20 to 49 years). In the age-group of 70 to 89 years the respective numbers are 1: 2.90 +/- 0.35 and 1: 2.99 +/- 1.04. The differences in the relations of surfaces between the different age-groups are statistically significant for both sexes (p less than 0.01; Student-t-test). The dye-injection showed that the main artery supplying the limbus glenoidalis is a branch of the arteria circumflexa scapulae. This branch is connected by several anastomoses with the arteriae circumflexa humeri anterior and posterior. These macroscopical observations were confirmed by histological and microangiographic examinations.(ABSTRACT TRUNCATED AT 400 WORDS)
