This study aimed to characterize follow-up outcomes of flexion and extension fixation
after zones I and II flexor tendon rupture repair. This nonrandomized controlled trialwith historical controls included 25 patients with flexor tendon ruptures of 30 fingers.
The flexion fixation group consisted of 12 patients (n=16 fingers) and the extension
fixation group consisted of 13 patients (n=14 fingers). The group with flexion fixation
comprised patients who slept with their injured fingers in the flexed position(intervention group). The group with extension was retrospectively selected between
April 2017 and March 2019, who slept with their injured finger in the extended
position (historical control group). Strickland assessments of the range of motion(ROM) of each joint at the conclusion of hand therapy, the ratio of total active motionof the repaired, to the healthy finger (%TAF), and IP joint extension limitation angles
were compared using Mann-Whitney U tests. Ratios of excellent and good ratings
based on the Strickland assessment were compared using Fisher exact tests. The
results of the Strickland assessment showed excellent or good outcomes for 22 (73%)
Abstractof 30 fingers, which was in line with our previous findings. Strickland ratings ofexcellent were achieved in seven (44%) of 16 fingers and four (28%) of 14 fingers in
the groups with flexion and extension fixation, respectively. The outcomes for two(22%) of 16 fingers and seven (78%) of 14 fingers in the groups with flexion andextension fixation were, respectively, rated as good. The proportion of patients rated
as excellent was significantly higher in the group with flexion than extension fixation(p=0.040). The %TAF and the active flexion angle of the distal interphalangeal (DIP)
joint were higher in the group with flexion than extension fixation (p=0008 and
p=0.025, respectively). Furthermore, the total angle of the IP joint limit of extension
did not significantly differ between the groups. Flexion fixation after flexor tendon
rupture achieved an excellent Strickland rating and was more effective thanextension fixation, especially in terms of the active flexion ROM of the DIP joint.
Flexion fixation might be an alternative to extension fixation because the range offlexion should be greater and might provide a range of finger extension motion
equivalent to that of extension fixation.
