Summary

We present the results of 360 degree release in the treatment of frozen shoulder.

Abstract

Purpose

of study: Frozen shoulder, characterised by functional restriction of both active and passive shoulder motion, is a prevalent condition accounting for 5% of all shoulder disease (Bunker, 2011). Open surgical release for frozen shoulder has been well reported, however more recently studies have described good functional and patient reported results following arthroscopic release.

Description of methods: Between 2013 and 2015, 15 patients (11 female, 4 male) who underwent arthroscopic release for frozen shoulder were included in this prospective, cohort study. The mean age at surgery was 55.3 years (42-63). Results are reported for 6 patients who have been reviewed at greater than 6 months post-release. Patients with either primary idiopathic and secondary post-traumatic frozen shoulders were included in this study. A complete full thickness release of all involved capsular tissue was performed arthroscopically with arthroscopic punches.


Summary of results: Pain intensity during normal activities at greater than 6 months post-release decreased on a 100 point VAS from 62.2 (SD=17.5) to 20.5 (SD=10.5). Overall function and quality of life was measured using the Oxford Shoulder Score (OSS) showing an increase from 16.6 (SD=6.5) to 34.8 (SD=11.9). The Constant Score showed an improvement in post-surgical measures of pain, function, movement and strength from 18.3 (SD=7) to 56.1 (SD=18.6). Shoulder active range of motion at 6 months post-release was: forward flexion 144 (SD=18.2), external rotation 63 (SD=7.4) and abduction 130.8 (SD=29.7).

Conclusion

Results of this prospective cohort are promising with patients reporting less pain, increased range of motion and strength resulting with greater function and a higher overall quality of life. These positive results indicate that arthroscopic release for frozen shoulder is an effective and safe alternative to open procedures.
