Variation in patient information and rehabilitation regimens after flexor tendon repair in the United Kingdom.

Introduction: There is clinical uncertainty regarding the optimal method of rehabilitation following flexor tendon repair. Many splint designs and rehabilitation regimens are reported in the literature; however, there is insufficient evidence to support the use of any one regimen. The aim of this study was to describe rehabilitation guidelines used in the United Kingdom (UK) following zone I/II flexor tendon repair. Methods: Using a cross-sectional design, hand units in the UK were invited to complete a short survey and to upload their flexor tendon rehabilitation guidelines and patient information material. Approval was granted by the British Association of Hand Therapists. Data were extracted in duplicate, using a pre-piloted form, and analysed using descriptive statistics. Results: Thirty-five hand units responded (21%), providing 52 treatment guidelines. Three splinting regimens were described, and all involved early active mobilisation: (i) long dorsal-blocking splint (DBS); (ii) short DBS; and (iii) relative motion flexion splint. Duration of full-time splint wear ranged from 4 to 6 weeks. There were variations in splint design and composition of home exercise programmes, particularly for the long DBS. Where reported, recommended return to driving ranged from 8 to 12 weeks, and return to light work activities ranged from 5 to 10 weeks. Discussion: Treatment guidelines varied across UK hand therapy departments, suggesting that patients receive differing advice about how to protect, move and use their hand after zone I/II flexor tendon repair. The disparity in splint wear duration, home exercise frequency and prescribed functional restrictions raises potential financial and social implications for patients. Future research should explore rehabilitation burden in addition to clinical outcomes.
