A biochemical evaluation of the restraints to posterior shoulder dislocation.

The biomechanics of posterior dislocation of the shoulder was evaluated using nine cadaver shoulders. Each was arthroscoped, roentgenograms were obtained, and then each was dislocated in a testing device. Force displacement data was obtained during testing, and posttesting roentgenograms, arthroscopic evaluation, and subsequent open dissections were performed to evaluate the pathology created. Although instability was created in all cases with displacement of the humerus to the diameter of the humeral head, force displacement of the humerus to the diameter of the humeral head, force displacement curves did not show an inflection point, implying a continuum between subluxation and dislocation. All shoulders had posterior Bankart lesions or posterior capsular lesions, or both. Anterior pathology was not seen. Posterior instability is most likely a continuum between subluxation dislocation with progressive injury to the posterior capsule and attachments such as the labrum as the principal restraint to posterior displacement.

[The subacromial shoulder dislocation].

We report on a case of subacromial shoulder dislocation, which resulted from a combination of a cranial glenoid fracture and an acromial fracture. The patient sustained this rare injury while playing handball. The whole implication of the injury was revealed only after extensive workup with CT scan of the shoulder. After reduction of the shoulder dislocation, the glenoid fracture was stabilized by osteosynthesis. The postoperative results showed anatomical reconstruction of the glenoid joint surface. After completion of therapy, the patient has achieved good functional results with a full range of motion (abduction 180 degrees ) and has been able to work full-time again.

A lesion of the musculocutaneous nerve. A rare complication of anterior shoulder dislocation.

A 47-year-old male patient with an anterior shoulder dislocation underwent reduction 3 days later. A residual neurologic injury remained, consisting primarily in weakness of shoulder and elbow flexion and sensory involvement of the ventral side of the forearm. Secondary sequelae included muscle atrophy with a concomitant frozen shoulder. The clinical examination and electromyography revealed a lesion of the musculocutaneous nerve, which is a very rare complication in shoulder dislocation.

Axillary artery rupture caused by shoulder dislocation.

A case of axillary artery disruption following an anterior shoulder dislocation is reported, the eleventh such case in the past 25 years. As an alternative to dividing the pectoralis major tendon, two incisions, infraclavicular and transaxillary incisions, were used to repair the artery with an interposition Dacron graft. An absent radial pulse following a shoulder dislocation suggests the possibility of axillary artery injury, usually a dissected intimal flap but occasionally a ruptured vessel. Early arterial repair is indicated, preceded by arteriography, if available. Brachial plexus injury frequently accompanies arterial damage and is not affected by arterial repair. Permanent, partial motor dysfunction is common, especially involving the extensors of the hand.

Anteroinferior shoulder dislocation: an auto-reduction method without analgesia.

OBJECTIVES: To describe a new reduction method for anteroinferior shoulder dislocations. DESIGN: Retrospective for the first thirty patients; prospective for the remaining seventy patients. SETTING: University hospital. PATIENTS: One hundred patients with anteroinferior shoulder dislocations. INTERVENTIONS: X-rays in two different projections were taken. The patient then was asked to sit on a relatively hard surface. The wrists were protected. The patients's forearms were placed around the homolateral knee, which is flexed at 90 degrees. The head of the examination table was lowered, and the patient was asked to lean backward with his or her neck in hyperextension. The patient had to push his or her shoulders (shrug) anteriorly, thus creating a rational movement of the scapula around a vertical axis. MAIN OUTCOME MEASURES: The authors analyzed initial prereduction x-rays and established a classification system based on the position of the humeral head, then assessed the success rate of the new technique with respect to the radiologic study. RESULTS: When using the reduction method described by Boss-Holzach-Matter, the authors attained an overall success rate of 60 percent, with a mean reduction time of three minutes and a time interval varying from fifteen seconds to nine minutes. CONCLUSION: The Boss-Holzach-Matter method is a reduction technique for anteroinferior shoulder dislocations that can be used without premedication or anesthesia. The authors recommend it for those patients who are not going to be sedated and for whom "quick" reduction and early discharge is desirable.

[The value of pneumo-arthro-CT in diagnosis after traumatic shoulder dislocation].

Traumatic subluxation of the shoulder in young patients may result in reluxation after further injury. 18 patients with traumatic subluxation and 22 patients with recurrent subluxation of the shoulder (after primary trauma) were examined by arthroscopy and pneumo-arthro-CT. This minimally invasive procedure showed high accuracy in the diagnosis of the typical glenoid margin and humoral head abnormalities. Nevertheless, arthroscopy cannot be abandoned for planning suitable operative treatment.

Arthroscopic extra-articular Bankart repair for the treatment of recurrent anterior shoulder dislocation.

This study describes a new arthroscopic procedure for the stabilization of recurrent anterior shoulder dislocations. The technique involves two important features. The first is the anterior inferior transmuscular approach through the subscapularis muscle, which permits self-locking implants to be inserted into the anterior inferior third of the glenoid rim so that they oppose the direction of pull of the capsule. This approach was studied on 79 cadaveric shoulders before clinical application. The second feature is the extracapsular (extra-articular) location of the self-locking implants, which permits a superomedial capsular shift as required. The technique offers a high degree of capsular stability. Of a total of 318 patients undergoing this procedure, the first 100 shoulders (98 patients) were evaluated postoperatively at an average of 35 months (range, 18 to 62 months). The diagnosis in all cases was traumatic recurrent anterior shoulder dislocation. Repair of the capsule was performed initially with screws and later with absorbable tacks. The overall recurrence rate was 9% (9 shoulders). Excluding the first 30 shoulders to take account of the learning curve, the recurrence rate for the subsequent 70 shoulders was only 5.7%. Limitation of external rotation at 0 degrees abduction averaged 6.7 degrees and 6.1 degrees at 90 degrees abduction for all shoulders; 61% of participants in overhead sports and 70% of participants in contact sports resumed their preinjury activities. The recurrence rate for patients involved in overhead sports was 10% and for collision sports it was 14%. There were no recurrences in the case of patients whose sports involve minimum risk to the shoulder (cycling, jogging). Most recurrences were observed in patients with lax shoulders and small Bankart lesions.

Reduction of anterior shoulder dislocations by scapular manipulation.

STUDY OBJECTIVES: This study examined the success rate, time required, technical ease, and reported patient discomfort for the use of scapular manipulation in the reduction of anterior shoulder dislocation. This study included a new variation of this technique using the seated position. DESIGN: Prospective case series over a 19-month period. SETTING: The emergency departments of a university and a community hospital. TYPE OF PARTICIPANTS: Patients with anterior shoulder dislocations. INTERVENTIONS: Emergency medicine resident and attending physicians were instructed in the technique of scapular manipulation in a classroom setting and requested to use this method initially for the reduction of anterior shoulder dislocations. Premedication was at the physician's discretion. MEASUREMENTS AND MAIN RESULTS: There were 54 patients with 61 dislocations. Scapular manipulation was attempted by 19 residents and 12 attending physicians. The overall success rate of scapular manipulation was 79%, whereas that of physicians experienced with the technique was 86%. Of the successful reductions, 65% were performed in less than one minute, and physicians rated the technique as very easy or easy to perform in 74% of these cases. No premedication was used in 64% of the attempts at scapular manipulation, and these patients reported pain ratings similar to those of the premedicated groups. No complications were noted in this study. CONCLUSION: Scapular manipulation generally is a simple, rapid, and reliable technique for the reduction of anterior shoulder dislocation.

Intraarticular pathology in acute, first-time anterior shoulder dislocation: an arthroscopic study.

Intraarticular soft tissue damage after first-time, acute shoulder dislocation has been poorly described in the literature. The present study describes 24 cases of first-time anterior shoulder dislocation that all were evaluated under anesthesia and examined via arthroscopy. All shoulders sustaining anterior dislocation show Bankart and Hill-Sachs lesions. They also show anterior instability. The arthroscopic findings were uniform and therefore cannot be used as predictors for future development of recurrent instability.

Longer immobilization extends the "symptom-free" period following primary shoulder dislocation in young rugby players.

The purpose of this study was to evaluate the effect of longer immobilization following primary shoulder dislocation in young rugby players for the prevention of recurrence. We sent a questionnaire regarding shoulder dislocation to all senior high school and college rugby teams in the southwest region of Japan. We received replies from 5476 players in 196 teams (i.e., answers were received from 76% of the teams). Based on the answers from the 79 rugby players who had undergone shoulder dislocations and who were eligible for the study, we divided them into two groups; group I: immobilization for 0-3 weeks at the time of the initial dislocation (n = 61), and group II: immobilization for 4-7 weeks (n = 18). We compared the time-course from primary dislocation to recurrence between the two groups, using the Kaplan-Meier method. The age range at the time of the primary dislocation was 14-23 years (average, 16.7 years). The probability of recurrence in groups I and II, respectively, was 78% and 44% after 1 year; and 85% and 69% after 2 years. The median period from return to rugby to recurrence was 4 months in group I and 14 months in group II. The symptom-free period was extended when immobilization was carried out for 4 weeks or more, in comparison with the symptom-free period in those who had immobilization for 3 weeks or less.

Closed reduction of anterior subcoracoid shoulder dislocation. Evaluation of an external rotation method.

We prospectively evaluated an external rotation method for closed reduction of acute anterior shoulder dislocations that had been described recently. Seventy-eight of 100 consecutive emergency patients who presented with anterior shoulder dislocations experienced successful reduction using this external rotation method. The method proved to be easy to perform and relatively safe. Based on our findings, we recommend that it be included in the physician's armamentarium for initial closed reduction of anterior shoulder dislocation.

[Treatment of unreduced anterior shoulder dislocation].

We evaluated the results of treatment in six patients with unreduced chronic anterior dislocations of the shoulder. In three patients the dislocations had not been recognized by the initial treating physician. In the remaining three patients the dislocations initially had been diagnosed but reduction had failed and the dislocations had remained unreduced. In one of the six shoulders the dislocation was left unreduced. The dislocation existed for 3.5 years and there was absence of disabling functional impairment, pain or neurovascular disturbance. In five of six shoulders the function was severely impaired. One of five shoulders with an anterior dislocation of three weeks duration could be reduced by closed manipulation. Four shoulders underwent open reduction. In all patients the humeral head could be preserved. Associated osseous lesions of the glenoid or the humeral head (Hill-Sachs lesions, fractures) were treated by rotation osteotomies according to Weber and the Eden-Lange-Hybinette procedure. Preoperatively all shoulders were graded as poor. Postoperatively the results in one was graded as excellent, in three as good and in one (algodystrophy of the left arm) as fair.

Reduction of shoulder dislocations under interscalene brachial blockade.

Even under short sedation, reduction of shoulder dislocations is often difficult, because of the reflectory contraction of the muscles around the humeroglenoidal joint in response to pain. Administration of interscalene brachial blockade produces analgesia and complete relaxation of the muscles of the shoulder joint. We report on ten consecutive shoulder dislocations which were reduced while the patients were under interscalene brachial blockade. In all cases, reduction was easy and free from complications.

[Experiences with Weber's subcapital rotation osteotomy in recurrent shoulder dislocation].

In 23 patients suffering from recurrent posttraumatic dislocation of the shoulder joint the derotation of the humeral head was performed as described by Weber. A description of the operative technique is given. As recommended by Weber an angled 1/2-tubular plate with 7 holes was used for stable osteosynthesis 17 times. After movement treatment removal of the osteo-synthesis-material was possible 6 to 8 months later. Because of high absence of recidivity with repair of full mobility and full strength the derotation of the humeral head is a treatment of choice in cases of recurrent posttraumatic dislocation of the shoulder joint.

The epidemiology of shoulder dislocations.

In an urban population of a quarter of a million, all shoulder dislocations that occurred in a 5-year period were recorded. A total of 216 shoulder dislocations were seen, 53.3% in men. The overall incidence rate was 17/100,000 per year. Incidence peaks were found in the age-group 21-30 years among men and in the age-group 61-80 years among women. Significantly more patients in the older age groups, and especially women, dislocated at home by falling on an outstretched arm, whereas the younger age-groups most frequently dislocated outside the home, e.g., on sports fields. A considerable number of patients (18.6%) were hospitalized, and 85.5% of the patients required outpatient follow-up. Prophylactic measures should be taken especially to increase the safety of the elderly in their homes.

External rotation method of shoulder dislocation reduction.

We used the external rotation method for reducing anterior shoulder dislocations on 85 consecutive patients seen in our emergency department during a one-year period. In relatively inexperienced hands, the external rotation method was successful on first attempt in 80% of cases. There were no complications attributable to the technique itself. We feel that it is a successful, easy, and atraumatic method of achieving reduction in both first occurrence and recurrent anterior shoulder dislocations.

Magnetic resonance imaging evaluation of capsulolabral tears after traumatic primary anterior shoulder dislocation. A prospective comparison with arthroscopy of 25 cases.

The purpose of our study was to evaluate the use of static magnetic resonance imaging (MRI) as a preoperative diagnostic tool in young patients with a traumatic primary anterior shoulder dislocation. Twenty-five patients who had acute primary traumatic anterior shoulder dislocation were examined with MRI and arthroscopy. The patients (18 male and 7 female) were between 16 and 39 years old (mean age, 27 years). They had no previous shoulder dislocations. The dislocations were confirmed radiographically. Examination with MRI and arthroscopy was performed within 10 days after the trauma. The MRI evaluation was performed before the arthroscopic examination, and the images were interpreted by an experienced magnetic resonance radiologist. No information from the MRI examination was available to the orthopedic surgeons before arthroscopy. The standard of reference for comparison was arthroscopy. Subacute MRI evaluation identified 15 labral tears, 12 Hill-Sachs lesions, 1 total rotator cuff lesion, 1 partial joint side rotator cuff lesion, and 1 partial rupture of the biceps tendon. Arthroscopic examination revealed 22 labral tears, 15 Hill-Sachs lesions, 1 total rotator cuff lesion, 1 partial joint side rotator cuff tear, 1 partial rupture of the biceps tendon, and 1 osseous Bankart lesion. Anterior capsulolabral tears and Hill-Sachs lesions appeared with a high incidence after acute anterior primary shoulder dislocation. Conventional MRI was only moderately reliable in the preoperative evaluation of labral tears and Hill-Sachs lesions, and it failed to give an accurate, differentiated preoperative diagnosis of the capsulolabral lesions.
