Abstract
Background
Atraumatic sternoclavicular joint (SCJ) instability is rare. Long-term outcomes are presented for patients managed with physiotherapy. A standardised method of assessment and treatment with a structured physiotherapy programme is also presented.
Methods
Long-term outcome was analysed in this prospectively collected series (2011-2019) of patients who were assigned to a structured physiotherapy programme for atraumatic SCJ instability. Outcome-measures (subjective SCJ grading of joint stability (SSGS score), Oxford shoulder instability score (OSIS adapted for SCJ) and visual analogue scale (VAS) for pain) were collected at discharge and long-term follow up.
Results
26 patients (29 SCJ's) responded (return rate 81%). Mean follow-up was 5.1 years (range 0.9-8.3 years). 17/26 patients were hyperlax. 93% (27/29) of SCJs achieved a stable joint on SSGS score. Mean OSIS score at long-term follow up was 33.4 (range 3-48) and VAS 2.7 (range 0-9). 95% who were compliant with physiotherapy had a stable SCJ (mean OSIS 37.8 (SD 7.3) and VAS 1.6 (SD 2.1)). Those non-compliant, 90% were stable but had lower function (mean OSIS 25 (SD 14, p = 0.02) and more pain, VAS 4.9 (SD 2.9, p = 0.006).
Conclusion
The structured physiotherapy programme is highly effective in treating patients with atraumatic SCJ instability. Compliance was essential in ensuring better outcomes.
