Abstract
Current evidence for flexor tendon repair management and outcomes performed at peripheral centres is unclear. Most studies are based on evidence from specialist hand centres. This study evaluated a peripheral hospital in New Zealand; where all flexor tendon repairs were performed by a generalist Orthopaedic service. The purpose of the study was to benchmark management and outcomes from a peripheral hospital in comparison to international standards. A retrospective single-centre consecutive case series of Zones I and II flexor tendon repairs was extracted between 1 January 2014 and 1 January 2018. Medical records were used to evaluate management and outcomes of repairs. Hand therapy notes were used to evaluate rehabilitation protocols provided. The primary objective was to measure re-rupture and re-operation rates. Secondary objectives included auditing operative management and hand therapy compliance. Forty-six patients (76 tendon repairs) were included in our final analysis. Mean follow up time to last clinical appointment was 11.8 weeks, and to last patient episode was 4.9 years. Most patients received timely surgery with a four-core repair using 3-0 or larger suture. All hand therapy followed a controlled active motion protocol. The re-operation rate was 19.6% (P = <0.05) and the re-rupture rate was 8.7% (P =0.28). Most flexor tendon injuries at this peripheral centre were managed according to international standards. However, high complication rates including re-operation and re-rupture occurred. Due to a lack of local comparison studies, confounding factors cannot be excluded as a contributor for these results.
