Shoulder Dislocation
Conditions
Brief summary
This study aims to measure the long-term efficacy of arthroscopic Bankart repair for first-time anterior shoulder dislocation in terms of recurrent instability and functional outcome.
Detailed description
Approximately half of patients who experience a dislocation of their shoulder will go on to experience further problems with their shoulder. Some people will suffer persisting instability, and notice an uncomfortable feeling of their shoulder wanting to give way. This can occur commonly during active movements such as playing sports or lifting heavy objects. Some patients experience recurrent dislocations, and find that their shoulder is so weak that it slips out of joint with little provocation. Previous research suggested that this high rate of subsequent shoulder problems can be greatly reduced (although not abolished completely) by surgery performed soon after the first dislocation. Ten years ago, there were two different methods which had been popularised: 1. Arthroscopic Wash-Out: The first is to wash out the shoulder joint with a sterile solution through an arthroscope (keyhole surgery) under a general anaesthetic. 2. Arthroscopic Repair: The second is to repair the torn tissues in the shoulder, again using key-hole surgery techniques under general anaesthetic. A previous clinical trial was undertaken in our unit (2001-2005) which randomised young patients aged under 35 years to one of the two possible treatments (described above). These procedures were not new or experimental. The same Arthroscopic Repair technique continues to be routinely used in NHS Lothian to treat patients who have late problems following a dislocated shoulder. We do not routinely perform wash-outs of the shoulder joint because this is only effective in treating problems that occur at an early stage.This new study intends to build on these findings by asking each of the patient groups to complete a short questionnaire which uses validated outcomes to measure their shoulder function. The aim of the study is to identify if there is a long-term clinical and functional benefit of early arthroscopic shoulder stabilisation in high-risk patients.
Interventions
PROCEDUREArthroscopic Washout Only
To wash out the shoulder joint with a sterile solution through an arthroscope (keyhole surgery) under a general anaesthetic.
PROCEDUREArthroscopic Bankart Repair
To repair the torn glenoid labrum in the shoulder, using key-hole (arthroscopic) surgery techniques under general anaesthetic. The Bankart technique is well described and will be performed using suture anchors.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Recurrent Dislocation | Up to 20 years post-surgery | Radiographic evidence of recurrent dislocation |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Western Ontario Shoulder Instability (WOSI) Index. | Up to 20 years post-surgery | Objective validated measure of instability-specific shoulder function. Comparison between pre-operative, 2 year post-operative and long-term (10-20 year) post-operative total score of each cohort. Total score is out of 2100. |
| Disabilities of Shoulder, elbow and Hand (DASH) scores | Up to 20 years post-surgery | Objective validated measure of general upper limb function. Comparison between pre-operative, 2 year post-operative and long-term (10-20 year) post-operative total score of each cohort. Score calculated to give a total out of 100. The lower the score, the better the function. |
