Abstract
There are a multitude of studies internationally that have considered the rates of redislocation of shoulders, where, after first time anterior dislocation, initial management has consisted of an internal rotation sling immobiliser or no immobility. The majority of these have indicated poor results. This is in comparison with recurrence rates of dislocation, post shoulder stabilisation (arthroscopic or open), after first time anterior dislocation, which have demonstrated excellent results.
The question remains, is there a non-operative alternative that will give similarly good results for these patients.
A selection criteria was set up for use of the external rotation brace for first time anterior dislocators. Thirty-five patients were used that fit the criteria and were able to be followed over time. A physiotherapy program was initiated at the two-week stage in combination with clinic reviews. We encouraged use of the brace for six weeks in total, with removal only for hygiene purposes. At two years, post first time anterior dislocation, patients were reviewed clinically and a quick DASH score performed. Any recurrence of dislocation was recorded and an MRI was also undertaken to show residual injury.
The compliance with the brace and physiotherapy program were excellent, with only one reported redislocation, during this period, in the 31 patients that were followed up. The majority of patients were functioning at predislocation levels at review and no one had required surgical intervention for instability. Quick-Dash results were also very good, with a vast majority scoring less than 2/100 level of disability.
Conclusion
The external rotation brace with a Physiotherapy program is an excellent alternative to early shoulder stabilisation for first time anterior dislocators.
