Abstract

Background

After arthroscopic shoulder stabilization, the loss of motion or delayed recovery of motion remains a clinical problem and may lead to poor patient satisfaction. There remains no consensus regarding the optimal position for postoperative immobilization and it is not known whether the position for shoulder immobilization has an effect on motion and functional recovery.

Questions/purposes

We asked: (1) Do patients treated with external rotation (ER) bracing after arthroscopic anterior shoulder stabilization reliably regain ROM and shoulder function? And (2) what is the frequency of recurrent instability and brace-related complications associated with the use of ER bracing?

Methods

Forty consecutive patients with a primary diagnosis of anterior shoulder instability underwent arthroscopic stabilization and received postoperative ER bracing; 33 patients (83%; mean age, 23 years; range, 13–44 years) were followed for at least 1 year postoperatively and seven patients were lost to followup. Shoulder ROM and functional scores were recorded preoperatively and at 2 weeks, 12 weeks, 6 months, and greater than 1 year (mean, 16 months) after surgery.

Results

All patients recovered their preoperative ROM and most patients achieved normal ROM by 3 months after surgery. Significant improvements in American Shoulder and Elbow Surgeons (ASES) and Western Ontario Shoulder Instability (WOSI) scores were observed at each postoperative time point. The mean (± SD) final scores were 95 ± 9 for the ASES and 87% ± 17% for the WOSI (p < 0.001 compared to preoperative scores). One patient (3%) developed recurrent instability. No patients underwent reoperation for the injured shoulder for any reason during the followup period.

Conclusions

ER bracing after arthroscopic shoulder stabilization is associated with a predictable recovery of ROM and functional score improvement. Future studies comparing ER bracing to traditional sling use should be conducted to determine the optimal method of postoperative immobilization.
