TL;DR: The incidence of recurrence seemed to be affectd very little by the type and length of immobilization of the shoulder following dislocation, and although a high incidence of Recurrence was noted in the group of patients for whom where was no immobilization or for whom there were very short periods of immobilized, long periodsof immobilization were not associated with a significant decrease in recurrence.
Abstract: 1. Five hundred shoulders in a series of 488 patients, with a follow-up study on 313 shoulders (63 per cent), are reviewed relative to prognosis.
2. The study included patients treated over the past twenty years, with a mean follow-up period of 4.8 years.
3. In 38 per cent of the patients the dislocation recurred.
4. Primary shoulder dislocations were found to occur as frequently after forty-five years of age as before forty-five.
5. The incidence of recurrent dislocation of the shoulder was very high in the second decade (92 per cent), but showed marked decrease after age fifty (12 per cent).
6. The age of the patient at the time of the primary shoulder dislocation was the most significant single prognostic factor.
7. Throughout this study, the average age of those patients in whom redislocation did not occur was greater than in those in whom dislocation did recur.
8. Various phases of trauma in relation to dislocations were reviewed. Usually the greater the initial injury, the lower was the incidence of recurrence.
9. Fracture of the shoulder girdle was a complication in 24 per cent. The incidence of fracture of the greater tuberosity was 15 per cent. This complication was accompanied by an appreciable lowering of the incidence of recurrence (7 per cent). The exception was in chip fractures of the anterior glenoid rim.
10. Humeral-head defects were present in 38 per cent of the primary dislocations and in 57 per cent of recurrent dislocations. These were associated with an increase in the incidence of recurrence (82 per cent).
11. From our figures, the incidence of recurrence seemed to be affectd very little by the type and length of immobilization of the shoulder following dislocation. Although a high incidence of recurrence was noted in the group of patients for whom where was no immobilization or for whom there were very short periods of immobilization, long periods of immobilization were not associated with a significant decrease in recurrence.
12. The incidence of recurrent dislocation relative to handedness was not significant.
13. Following primary or initial dislocation, 70 per cent of the dislocations which recurred did so within two years.
14. Following operative procedures for the repair of recurrent shoulder dislocation, 52 per cent recurred within two years after operation.
15. The incidence of posterior dislocation was 2 per cent.
16. The incidence of bilateral dislocation was 2.4 per cent.
17. The incidence of associated nerve injury was 5.4 per cent.
18. The incidence of epileptics with shoulder dislocations was 2 per cent.
TL;DR: It is concluded that persistent generalised joint laxity, which is often familial, is an important predisposing factor to congenital dislocation of the hip in boys and less important in girls, except perhaps in familial cases, as in girls there is an alternative temporary hormonal cause of joint laxities.
Abstract: 1. General joint laxity affecting more than three joints was found in 7 per cent of normal schoolchildren. Similar laxity was found in fourteen of a random series of forty-eight girls, and in nineteen of twenty-six boys, with non-familial congenital dislocation of the hip. Such laxity was also found in four of seven girls and five of seven boys with familial (first degree relative affected) congenital dislocation of the hip. 2. It is concluded that persistent generalised joint laxity, which is often familial, is an important predisposing factor to congenital dislocation of the hip in boys. It is less important in girls, except perhaps in familial cases, as in girls there is an alternative temporary hormonal cause of joint laxity.
TL;DR: LPS is the most prominent form of instability of the knee in patients complaining of "giving way" of the knees, and recovery from severe soft-tissue injury to the knee joint.
Abstract: The lateral pivot shift(LPS) is a special form of lateral compartment instability arising from anterior cruciate insufficiency. It is characterized by anterior subluxation of the tibial plateau out from beneath the lateral femoral condyle. As a consequence of this form of instability, deleterious changes of the knee joint take place, including meniscal tears, and articular cartilage erosions. The eventual result of continued symptomatic instability is late osteoarthritis of the knee. LPS is the most prominent form of instability of the knee in patients complaining of "giving way" of the knee, and recovery from severe soft-tissue injury to the knee joint.
TL;DR: In my experience of over thirty cases only once has true dislocation recurred after this operation, and this reinforces Watson-Jones's advice that the original dislocation should be treated by complete immobilisation in full medial rotation for three weeks.
Abstract: 1. Coracoid transplantation for recurring dislocation of the shoulder is described.
2. In my experience of over thirty cases only once has true dislocation recurred after this operation. Recurrence was due to avulsion of the bone block.
3. Failure to repair the original detachment of the glenoid labrum is a frequent cause of recurrence of dislocation of the shoulder. An explanation is offered for this failure; namely that the injured labrum adheres to the deep surface of the subscapularis muscle instead of reattaching itself to bone. This reinforces Watson-Jones's advice that the original dislocation should be treated by complete immobilisation in full medial rotation for three weeks.
