Abstract
Objectives: To evaluate the outcomes of the repair of flexor digitorum
Profundus (FDP) alone versus its repair combined with flexor digitorum
superficialis (FDS) repair in Zone II flexor tendon injury.
Background: Flexor tendon injuries in zone II of the hand present a
challenging problem for hand surgeons. Injuries involving the FDP and
FDS tendons require careful assessment and planning. The primary
goals of repair are to achieve optimal tendon healing, maximize range of
motion, and restore functional strength.
Methods: A total of 24 patients presenting with FDP and FDP injury at
zone II were surgically treated from 2020 to 2022. The patients were
divided into two groups where Grpup A (repair of FDP only), and Group
B (both FDP and FDS were repaired). The functional outcomes were
assessed using the Tang grading system, total passive range of motion,
and Grip strength.
Results: Twelve patients (21 fingers) had FDP only repair, while in
group B (19 fingers) had both FDP and FDS repaired. There were no any
significant differences between the two groups regarding range of
movement and grip strength, but there was a significant difference
regarding the quickDASH score. The patients with FDP only showed
significantly less flexion deformity at the operated digits PIP joint (p<
0.008). Conclusions: In conclusion, the decision regarding FDP repair
alone or combined FDS and FDP repair in zone II is highly individualized
and based on a comprehensive evaluation of the specific injury, the
condition of the tendons, and the patient’s functional goals.
