Abstract

To compare the clinical effectiveness of three splints after repair of zone 1 and 2 flexor tendons: forearm based (long), Manchester short (short), and relative motion flexion (mini) splints.
Prospective, randomised, parallel group, pragmatic, superiority, clinical trial.
26 UK hospitals.
430 participants (aged ≥16 years) requiring rehabilitation after primary repair of zone 1 and 2 flexor tendons in one or two fingers of the hand according to British Society for Surgery of the Hand guidelines.
Participants were randomly assigned 1:1:1 to the long, short, or mini splint. Splints were worn continuously for five weeks and intermittently for a further week at night and in vulnerable situations such as public environments. Masking participants was not possible owing to the nature of the intervention.
The primary outcome was the mean post-randomisation score on the patient-rated wrist and hand evaluation (PRWHE) instrument at 6, 12, 26, and 52 weeks, analysed by intention to treat.
430 participants were randomised to the long splint (n=143), short splint (n=140), or mini splint (n=147) and 403 were included in the intention-to-treat analysis. Adherence, defined as wearing the splint for a minimum of five weeks, was 83% (118/143) for the long splint, 76% (106/140) for the short splint, and 78% (115/147) for the mini splint. Mean post-randomisation PRWHE scores were 24.5 (standard deviation 15.5) in the long splint group, 23.5 (16.7) in the short splint group, and 22.4 (15.0) in the mini splint group, with adjusted between group differences of 0.3 (98.3% confidence interval -4.0 to 4.6, P=0.88) for the long versus short splint, 2.3 (-1.9 to 6.5, P=0.19) for the long versus mini splint, and 2.0 (-2.2 to 6.3, P=0.25) for the short versus mini splint. Serious adverse event rates occurred in 10% (14/143) of participants in the long splint group, 11% (15/140) in the short splint group, and 11% (16/147) in the mini splint group.
This trial found no statistically significant difference in clinical effectiveness between the long, short, and mini splint. Apart from some small differences, secondary outcomes were comparable across all three groups.
