Short-term Complications of Open Latarjet Procedure for Recurrent Anterior Shoulder Dislocation.

Anterior dislocation is the most common type of shoulder dislocation, and even after appropriate treatment, recurrence after a primary traumatic anterior dislocation is highly frequent. Surgical options for treating recurrent anterior dislocations mainly include Bankart arthroscopic and Latarjet open surgery. We aimed to evaluate the outcomes and complication rates of the open Latarjet procedure in a series of patients with recurrent anterior shoulder dislocation. A total of 55 patients with recurrent anterior shoulder dislocation who underwent an open Latarjet procedure were included in this retrospective cohort study. Shoulder range of motion and postoperative complications, including neurapraxia, re-dislocation, hematoma, infection, dehiscence, implant failure, and pain, were evaluated. The mean age of the patients was 27.7 ± 6.5 years . The mean time interval after the first dislocation was 3.4 ± 2.7 years . The mean preoperative and postoperative forward flexion (P = 0.200), abduction (P = 0.200), external rotation (P = 0.066), and internal rotation (P = 0.310) were not significantly different. Postoperative complications included 1 case of postoperative musculocutaneous nerve neurapraxia, 1 case of re- dislocation, 1 case of wound dehiscence, and 2 cases of screw breakage. Postoperative pain was also recorded in 11 (20%) patients that were either in the form of occasional night pain (n = 6) or activity-dependent pain (n = 5). Open Latarjet procedure is an efficient procedure for the treatment of recurrent anterior shoulder dislocation. However, its rate of complications remains relatively high, and surgeons must consider this drawback in their decision-making and address patients' expectations.

Conservative management following closed reduction of traumatic anterior dislocation of the shoulder.

Acute anterior dislocation is the commonest type of shoulder dislocation and usually results from an injury. Subsequently, the shoulder is less stable and more susceptible to redislocation, especially in active young adults.To compare methods of conservative (non-surgical) management versus no treatment or different methods of conservative management after closed reduction of traumatic anterior dislocation of the shoulder. Interventions include methods of postreduction immobilisation and rehabilitation.We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register (March 2005), the Cochrane Central Register of Controlled Trials (The Cochrane Library Issue 3, 2005), MEDLINE, EMBASE, the National Research Register (UK), conference proceedings and reference lists of articles.Randomised or quasi-randomised controlled trials comparing various conservative interventions versus control (no or sham treatment) or other conservative interventions applied after closed reduction of traumatic anterior dislocation of the shoulder.All authors selected trials, assessed methodological quality and extracted data. Study authors were contacted for additional information.One flawed quasi-randomised trial was included. A "preliminary report" gave the results for 40 adults with primary traumatic anterior dislocation of the shoulder treated by post-reduction immobilisation with the arm in either external or internal rotation. There was no statistically significant difference between the two groups in the failure to return to pre-injury sports by previously active athletes, in redislocation or shoulder instability. Similar numbers of participants of the two groups removed their immobiliser before one week had passed.There is a lack of evidence from randomised controlled trials to inform the choices for conservative management following closed reduction of traumatic anterior dislocation of the shoulder. Sufficiently powered, good quality, well reported randomised controlled trials with long-term surveillance of conservative management are required. In particular, trials examining the type and duration of immobilisation would be useful.

Evaluation of immobilization in external rotation after primary traumatic anterior shoulder dislocation: 5-year results

It is still not clear which method is the most efficient for treating primary traumatic anterior shoulder dislocation. Immobilization in external rotation has become increasingly discussed within the last 10 years. The aim of this study was to evaluate the rate of recurrence and clinical outcome of the immobilization in external rotation after primary traumatic anterior dislocation within a midterm period of 5 years. Additionally, a summary of literature is given according to the present knowledge of this issue. From May 2004 to May 2006, 28 patients with primary traumatic anterior shoulder dislocations were included in a prospective MRI-controlled study. After a follow-up of 5 years, the recurrence rate and clinical outcomes of the patients were evaluated using clinical scores (Constant and Murley score, Western Ontario Shoulder Instability Index, Rowe score). After 5 years, 26 patients (93 %; males, n = 25; female, n = 1; mean age, 29.3 years) were interviewed concerning re-dislocations. In the meantime, four patients (15 %) experienced a re-dislocation (ø 12.2 months) after the end of the immobilization. Overall, 21 patients (75 %) were included in a clinical follow-up (CM score: ø 92.8 points; Western Ontario Shoulder Instability Index: ø 87 %; Rowe score (in 17 patients): ø 94.2 points). Upon clinical examination, unidirectional anterior instability was found in one patient, which corresponds to an overall instability rate of 19 % within the examined patient population including the re-dislocations. Immobilization in external rotation shows satisfactory results after 5 years in regard to recurrence and instability rates and clinical outcomes. The data show that with immobilization in external rotation, re-dislocations occur within the first 2 years.

Bracing in external rotation for traumatic anterior dislocation of the shoulder

We undertook a prospective study in 51 male patients aged between 17 and 27 years to ascertain whether immobilisation after primary traumatic anterior dislocation of the shoulder in external rotation was more effective than immobilisation in internal rotation in preventing recurrent dislocation in a physically active population. Of the 51 patients, 24 were randomised to be treated by a traditional brace in internal rotation and 27 were immobilised in external rotation of 15 degrees to 20 degrees. After immobilisation, the patients undertook a standard regime of physiotherapy and were then assessed clinically for evidence of instability. When reviewed at a mean of 33.4 months (24 to 48) ten from the external rotation group (37%) and ten from the internal rotation group (41.7%) had sustained a further dislocation. There was no statistically significant difference (p = 0.74) between the groups. Our findings show that external rotation bracing may not be as effective as previously reported in preventing recurrent anterior dislocation of the shoulder.

Management of shoulder dislocation—are we doing enough to reduce the risk of recurrence?

Young patients with shoulder dislocation are at high risk of recurrence. Traditionally, management has been conservative, but rehabilitative programmes are successful in fewer than 20% of patients. Recent studies suggest that early surgical intervention (arthroscopic lavage or stabilisation) can significantly reduce recurrence in young patients with primary traumatic anterior dislocation. This study demonstrated that in our region, 21% of all patients presenting with shoulder dislocation had already suffered recurrence at 1 year; in the 15–22 years age group this figure was 43%. We propose to offer young patients presenting with primary traumatic anterior dislocations arthroscopic lavage within 10 days of injury. The extra surgical workload is manageable within our current trauma service arrangements, and we believe that this form of treatment would be acceptable to patients.

Early arthroscopic treatment of primary traumatic anterior shoulder dislocation. A follow-up study.

This study evaluates the results of early arthroscopic Bankart repair in patients with primary traumatic anterior dislocation of the shoulder. The patients' age range was 17-34 years. Arthroscopic Bankart repair was performed within 12 days after the dislocation. First follow-up was at 18 months. According to Rowe's score, 11 patients (73%) were excellent, 3 (20%) were good and 1 (7%) was poor. The median external rotation deficit was 4 degrees in the adducted position. At a second follow-up at 34 months, two patients had redislocated. Both of these patients had severe generalized joint laxity. Another patient reported frequent subluxations. We conclude that in young patients with primary anterior traumatic shoulder dislocation, early arthroscopic Bankart repair implies a low recurrence rate and restores shoulder function to normal. Generalized joint laxity could indicate an increased risk for recurrent dislocation.

Recurrence after primary traumatic anterior dislocation of the shoulder is common. The rate of recurrence is generally thought to be about 20%, and to be related to factors of age, force and situation of injury, length of immobilization complications of primary dislocations, and instability of the shoulder joint. However, a case of recurrence is still a matter of speculation and few reports to be concerned with the rate of recurrence of primary dislocation have yet been in Japan.About 170 cases were assesed at our University and neighboring hospitals, and the relation between primary dislocation and recurrence were investigated. We studied and examined 104 cases of traumatic dislocation, age, force and situation of injury, length of immobilization, complication of dislocation, and of 66 cases of recurrence, we studied the situation of primary injury and interval of recurrence.
