Introduction: Scapholunate instability is commonly caused by a fall on an outstretched hand resulting in structural pathology and pain. In recent years, dynamic stability mechanisms have been described that may aid in the non-operative management of this patient group. Limited evidence exists regarding the clinical application of stability mechanisms for scapholunate instability, and there is a void of reproducible structured exercise regimes. Method: A service evaluation was conducted over 16 months to assess patient outcomes following an evidence-based treatment protocol in the conservative management of stage one scapholunate instability. Pain-free grip, maximal grip, grip strength ratio, Euro-Qol five dimensions questionnaire (EQ-5D), Visual Analogue Scale (VAS) and Quick Disability of Arm, Shoulder and Hand questionnaire (Quick-DASH) scores were compared between baseline and final follow-up. Results: Six consecutive patients (seven wrists) were included with five patients (six wrists) completing treatment. Mean grip strength ratio improved by 45%, mean VAS improved by 5.5 points, mean Quick-DASH improved by 33.96% and EQ-5D improved by 0.187 quality-adjusted life years. Where established, all outcomes exceeded minimal clinically important difference values. Discussion: The Birmingham Wrist Instability Programme can yield clinically important results for patients with stage one scapholunate instability in the short term based on a small service evaluation. The findings support the need for further research to evaluate the rehabilitation programme in a larger group of patients over the longer term.
