An operative technique for recurrent shoulder dislocations in older patients.
Recurrent anterior shoulder dislocation in the elderly is not as exceptional as it was once thought to be. That anterior shoulder dislocation in older patients is caused by a rotator cuff tear through the posterior mechanism is well accepted. However, in the subset of patients who have multiple recurrent or intractable dislocations develop, there may be combined pathologic conditions at work: large or massive rotator cuff tears together with anterior capsulolabral injuries such as a Bankart lesion or fracture of the glenoid rim. These patients have multiple recurrences because of disruption of both the anterior and the posterior stability mechanisms. We suggest a procedure that provides anterior stabilization with the capsular shift technique and that is supplemented by Bankart repair as necessary. The capsule transfer is performed superiorly and posteriorly to close the defect in the cuff. In this way a capsulodesis effect can be achieved that displaces the humeral head downward and produces active centering of the head in the course of abduction. Use of only the anterior capsule for the shift, and not the subscapularis tendon, does not compromise subscapularis function. Between 1990 and 1996, we used this technique to treat 16 patients older than 55 years of age with multiple recurrent anterior shoulder dislocation and massive rotator cuff tear. We report the results for the first 10 patients with a minimum follow-up of 2 years (range 2 to 7 years) and an average follow-up of 52 months. There were 7 excellent results, 2 good results, and 1 fair result according to the Rowe criteria. None of the patients had a recurrence of the dislocation. All the patients regained full or functional range of motion with stable shoulders, and most of them could perform activities of daily living without limitation. The average Constant score was 83%. This procedure appears to be successful in treating older patients with recurrent shoulder dislocation.

Has the management of shoulder dislocation changed over time?
Anterior shoulder dislocation is a disabling injury affecting all ages, young and old alike. Recently, the treatment of traumatic shoulder dislocation has included immobilisation for varying periods of time followed by physiotherapy. This study is the first in this country to address the demographic data and recurrence rates of shoulder dislocation. Three hundred and eight patients (170 men and 138 women) were followed up for an average of 5.9 years. The most frequent mechanism of injury was a fall (65.66% of cases), and in 92.1% of the patients, the shoulder was reduced in the Emergency Department without the need for sedation or general anaesthesia. The overall recurrence rate in all ages was 50%, but rose to 88.9% in the 14-20-year age group. The duration of immobilisation did not affect the rate of re-dislocation of the humeral head. We believe that conventional shoulder immobilisation in a sling offers no benefits, and it would be preferable not to immobilise the shoulder at all.

Bilateral locked posterior shoulder dislocation in a footballer.
Posterior dislocation of the shoulder is an uncommon injury, accounting for between 2% and 4% of all shoulder dislocations. It occurs most frequently in patients following convulsions or direct anterior force to the shoulder. It is a particularly uncommon injury in sport. This paper reports an unusual case of bilateal locked posteriorly dislocated shoulders in a previously healthy young man who fell while playing football.

Arthrography in acute shoulder dislocations.
Arthrography of the shoulder was performed on 50 patients with acute traumatic shoulder dislocations. The mean interval between injury and arthrogram was 2.3 days, with a median interval of one day. Anterior dislocations occurred in 96% of patients, and posterior dislocations in 4%. Initial dislocations were present in 74%, and recurrent dislocations in 26%. The most frequent abnormality identified or arthrograms was an enlarged but intact shoulder capsule (58%), most commonly seen in shoulders subject to recurrent dislocations (77%). Shoulder joint capsular tears or disruptions were seen in 48% of the patients. The next most common lesion was fracture (52%), identified on standard roentgenograms. These included Hill-Sachs lesions (28%), greater tuberosity fractures (22%), and coracoid fractures (2%). Ruptures of the rotator cuff, present in 28% of the cases (14 patients), occurred more frequently in initial dislocations (62%) than in recurrent ones (36%). The high frequency of enlarged intact shoulder capsules, even after an acute initial joint dislocation (58%), suggests that the humeral head does not routinely rupture the capsule during dislocation, but rather tears the glenoid labrum at its bony attachment and dislocates subperiosteally, dissecting a false pouch below the periosteum and under the subscapularis.

Anterior shoulder dislocation and injuries of the rotator cuff in patients aged over 40 years. Clinical and sonographic study.
A total of 39 patients with a mean age of 64 years (41 to 88) who had had anterior shoulder dislocation were followed-up an average of 2 years after trauma in order to evaluate the conditions of the rotator cuff. All of the patients were evaluated clinically, radiographically, and sonographically. Clinical evaluation revealed significant differences between the dislocated shoulders and the contralateral ones: the mean Constant score was 67 in the group with dislocated shoulders and 87 in the contralateral group. Ultrasound revealed partial injury of the cuff in 31% of cases and complete injury in 28%. Mean score was 81.4 in the group with a normal ultrasound, 67.1 in that with partial injury of the cuff, and 46.5 in that with complete injury of one or more tendons. These data confirm the high frequency of partial or complete injuries of the rotator cuff in patients aged over 40 years that have undergone anterior shoulder dislocation. Ultrasound confirms it is an excellent diagnostic method in the pathology of the rotator cuff, demonstrating good correlation with the clinical evaluation.

Acute complications associated with shoulder dislocation at an academic Emergency Department.
Shoulder dislocation is the most frequent dislocation treated in the Emergency Department (ED). Orthopedic literature cites up to a 55% incidence of fracture, vascular or neurologic injury associated with this injury, but these studies suffer from referral bias. No large ED series has been reported. This retrospective chart review was conducted in an academic ED for patients with shoulder dislocation presenting July 1, 1995-June 30, 2000. There were 263 charts identified; 73 were miscoded and 5 were lost, leaving 190 for analysis. Mean age was 34.3 years. Fifty-five patients had at least one fracture (29%), 48 of which (76%) were of the Hill-Sachs type. Despite presence of a fracture, all shoulders underwent successful ED reduction. Sensory nerve deficits were found in 24 (12.6%), which persisted after reduction in 25% of these patients. No vascular injuries were identified. The finding of fracture in 33% of patients with shoulder dislocation is in the range of rates reported in the orthopedic literature (15-55%). The finding that, despite the presence of a fracture, all underwent successful closed reduction is important, as one-third of these patients will have this condition. Neurologic deficits in 12% is significantly lower than the 21-65% reported in the orthopedic literature. Although complications associated with shoulder dislocation were relatively common, they did not significantly affect ED management.

Modified Bankart procedure for recurrent anterior shoulder dislocation.
BACKGROUND AND PURPOSE: Recurrent anterior shoulder dislocation is a serious condition, for which the Bankart procedure is a standard treatment. Having made three modifications to the original procedure, we examined the efficacy of this modified Bankart procedure in the treatment of patients with recurrent anterior shoulder dislocation. PATIENTS AND METHODS: The medical records of 21 patients who received a modified Bankart procedure for recurrent anterior shoulder dislocation during the period from 1989 through 1998 were retrospectively analyzed. The average age at initial dislocation was 22 +/- 5 years. The average postoperative follow-up period was 41 +/- 16 months. Three of the patients complained of mild shoulder pain before their operation. RESULTS: The postoperative loss of external rotation and abduction compared with the nonoperated side was 9 +/- 4 degrees and 5 +/- 4 degrees, respectively. There were no limitations in daily activities during follow-up. No patient had shoulder pain after surgery. Redislocation occurred in one patient during the follow-up period. Patient satisfaction was rated as excellent by 20 (96%) patients and poor by one. CONCLUSION: This modified Bankart procedure is a technically easy operation with a low complication rate, a high rate of patient satisfaction, and a low redislocation rate. It is a procedure of choice for the management of traumatic recurrent anterior shoulder dislocation.

Bilateral anterior shoulder dislocation: a case report.
Bilateral anterior shoulder dislocation is a very rare clinical entity. All the cases reported so far highlight a simultaneous bilateral shoulder dislocation. We report an unusual case, where the left shoulder dislocated first due to trauma followed by atraumatic dislocation of the right shoulder. A new manoeuvre--the Spaso Technique was used to reduce the dislocation.

Restraining patients and shoulder dislocations during seizures.
We describe 3 patients whose shoulders dislocated as the movements of the arm were restricted during a generalized tonic clonic seizure over an 18-month period. The first patient had both shoulders dislocated when observers sat on his arms during the convulsion. The second patient had a convulsion while in a forced lateral decubitus position and dislocated the shoulder on that side. The third patient dislocated the shoulder and fractured the acromion as she was held by her arms in a chair during a convulsion. Despite the large number of patients with refractory epilepsy under our care, no cases of spontaneous shoulder dislocation occurred during that period of time.

[Limbus-plasty in recurrent anterior shoulder dislocation].
We are reporting the results of labrum reconstruction following recurrent dislocations of the shoulder. From 1985 to 1988 35 patients (27 male/eight female) aged 28.4 years on the average (20 to 45 years old) had surgical treatment. 33 of these 35 came in for a follow-up about 40 months later (28 to 60 months). So far, only one patient suffered a re-dislocation from major trauma. In that case, therapy was continued on a conservative basis and the patient has been free of complaints and re-dislocation for three years. No one of the remaining 32 patients had another dislocation. Shoulder mobility is normal in 29 patients. One patient's abduction is impaired by 10 degrees and one has a 10 degrees to 15 degrees impairment of outward rotation. 30 patients have no complaints whatever. 32 patients consider the outcome satisfactory and only one does not. 30 of 33 patients say their dexterity in sports is the same as prior to the accident and only three feel slightly impaired during competitive sports.

Scapular manipulation technique for reduction of traumatic anterior shoulder dislocations: experiences of an academic emergency department.
BACKGROUND: Shoulder dislocations account for almost 50% of all joint dislocations, which are most commonly anterior (90-98%) and occur due to trauma. This prospective study was conducted to report our experiences of using the scapular manipulation technique (SMT) to reduce traumatic anterior shoulder dislocations. METHODS: Between March 2002 and March 2003, SMT was applied to 41 patients who presented with traumatic anterior shoulder dislocation to the Gulhane Military Medical Academy, Department of Emergency Medicine, Ankara, Turkey, which is a level 1 trauma centre with an annual attendance of 85,000 patients. The technique was applied to patients in the prone position by a single operator. Where necessary, a procedural sedation/analgesia (PSA) protocol was followed. RESULTS: The study population consisted of 26 (63.4%) male patients aged between 17 and 76 years (SD 15.6). History of recurrent shoulder dislocations at the same site were taken from seven (17.1%) of the patients. Mean (SD) trauma to reduction time was approximately 61.5 (72) minutes (range 10-480). Five patients (12%) had a greater tuberosity fracture. SMT was attempted twice to only four (9.8%) patients by a standard PSA protocol. We experienced a success rate of 90.2% at the first attempt and 100% overall. None of the patients encountered any complication. CONCLUSIONS: We report the successful use of SMT in the prone position for the reduction of traumatic anterior shoulder dislocations, mainly without requirement of any sedatives or opiate analgesics. We believe that SMT may also be applied by inexperienced physicians, as it is simple, applicable, and easily understood. As no single method has a 100% success rate, SMT is a useful one to know.

[Concomitant osseous and ligamentous injuries of traumatic shoulder dislocation and its significance for the pathogenesis of habitual dislocation].
161 consecutive patients with traumatic shoulder luxation between 1975 and 1983 are followed, concerning their evolution to recurrent shoulder dislocation. In 26 patients there was a recurrent shoulder dislocation in a mean time of 19 months after the first luxation. In literature the common level of recurrent dislocation is higher than our 16.1%, despite of the shorter immobilising time after the first shoulder luxation in our center. When there is no evolution to recurrent dislocation, a stable shoulder and a normal shoulder function without pain can be expected in 95%. The compression fracture of the humeral head and the avulsion of the glenoid margin were made responsible for the recurrent dislocation, mostly appearing in adult men, younger than 35 (55% of all recurrent dislocations). Because avulsion fractures of the tuberculum majus don't lead to an unstable fracture neither the existence of a compression defect in the humeral head is pathognomonic for an unstable shoulder, nor a lack of such radiological appearance excludes a recurrent dislocation. In first instance rotatory cuff injuries could be responsible for the instability of the shoulder joint. All patients with this invalidating injuries should be stimulated to an operative procedure, because after correction of an unstable shoulder by a derotation osteotomy of Weber or the elevation of the anterior margin of glenoid in the technique of Trillat good results with normal functional capacities of the shoulder can be expected.

Posterior shoulder dislocation: avoiding a missed diagnosis.
Posterior shoulder dislocation is a relatively uncommon event, with an incidence of 1% to 4% of all shoulder dislocations. Because of the infrequency of this condition, the diagnosis is often missed, with significant consequences to the patient Injury in the athlete is usually from a direct blow or fall onto an outstretched arm. After such an injury, symptoms may be confused with a shoulder contusion or rotator cuff injury. Significant complications such as chronic posterior dislocation and degenerative disease of the shoulder can occur if the diagnosis is missed. A careful history and physical examination, complete radiographic evaluation, and a high level of suspicion are required to identify posterior shoulder dislocation. Treatment consists of prompt closed reduction, or operative repair if this is unsuccessful.

Reduction of acute anterior shoulder dislocations: comparing intraarticular lignocaine with intravenous anesthesia.
Anterior shoulder dislocation is the most common dislocation in the body. Various methods of anesthesia are available for reduction. The objective of this study was to compare the application of intra-articular anesthesia with intravenous anesthesia for reduction of acute anterior shoulder dislocation. This study was conducted at Kathmandu Medical College Teaching Hospital (KMCTH) and Kathmandu Hospital and comprised of patients coming with anterior dislocation of shoulder from July 2001 to June 2005. Forty-five patients aged 17-55 years with no associated fractures of adjoining bones were included in the study. In twenty-three patients, reduction was done using intra-articular anesthesia and in 22 patients intravenous anesthesia was given. In five patients (three in intra-articular group and two in intravenous group) the reduction technique had to be changed to the Hippocratic method. In these three patients intravenous anesthesia had to be given after intra-articular anesthesia failed to relieve pain and spasm. In the intravenous group two patients had to be admitted overnight while in the intra-articular group none had to be admitted to the hospital. However, in the intra-articular group the average time taken from injection to reduction was significantly longer (<.001). The use of intra-articular lignocaine for reduction of shoulder dislocation is safe and effective especially when patients present early. In patients presenting late (more than 5 hours) intravenous anesthesia should be primarily considered as the method for shoulder reduction.

A new drug free technique for reducing anterior shoulder dislocations.
Five cases of anterior shoulder dislocation are reported. The dislocations were reduced quickly, painlessly and without the use of drugs using the 'Cunningham technique.' The practice and theory of the technique are described. The 'Cunningham technique' is a useful single operator method of reducing anterior shoulder dislocations. Further research is being undertaken to reproduce the results in a larger patient group and also to examine how easily the technique can be taught.

[Posterior shoulder dislocation. An often overlooked injury].
Posterior dislocation of the shoulder is rare. Only 2% of dislocated shoulders are displaced posteriorly, and these are chiefly of the subacromial type. Over 60% of the cases are not diagnosed initially because the arm is held in the normal position of adduction and internal rotation. The most consistent findings on physical examination are: the fixed internal rotation of the arm and the characteristic movement of the scapula with abduction of the upper extremity. It is essential that appropriate radiographs are obtained to correctly diagnose the dislocation. While the routine anteroposterior shoulder film is often enough to diagnose various anterior dislocations, it is not sufficient to diagnose the subacromial type of posterior dislocation. We recommend an anteroposterior view and an axillary lateral or tangential scapula view.
