Résumé
Tenolysis is an established treatment for flexor tendon adhesions at the hand. Concomitant finger nerve injuries with incomplete reinnervation may negatively influence outcomes. This study investigates the impact of finger nerve injuries on outcomes of flexor tendon tenolysis. A retrospective pair-matched study was conducted, including patients undergoing tenolysis for flexor tendon adhesion after primary repair of isolated superficial and deep flexor tendon injury and both finger nerves (test group [TG]). These were compared with patients (control group [CG]) with similar injuries without affection of nerves and pair-matched in age, zone of injury and follow-up. Patients' demographics, finger sensitivity, total active range of motion (TAM) before and after tenolysis and complications were retrieved. For both study groups, 10 patients each were included in this study. There were no significant differences regarding patients' demographics and follow-up. Mean follow-up was 37 (CG) and 41 (TG) months. Total active range of motion was preoperatively 81 ± 47° (CG) and 68 ± 54° (TG) and reached postoperatively 125 ± 57° (CG) and 79 ± 43° (TG). Hence, TAM improvement was significantly higher in patients without nerve damage (58 ± 16 vs 21 ± 11%; P > 0.05). Tendon ruptures occurred significantly more frequent in patients with nerve injury (n = 0.4 ± 0.52) compared with patients of the CG (n = 0; P < 0.05). This study shows that finger nerve injury with incomplete recovery after combined flexor tendon and nerve injuries of the finger negatively influences the outcomes of flexor tendon tenolysis.

BACKGROUND
Tenolysis is an established treatment for flexor tendon adhesions at the hand. Concomitant finger nerve injuries with incomplete reinnervation may negatively influence outcomes. This study investigates the impact of finger nerve injuries on outcomes of flexor tendon tenolysis.
METHODS
A retrospective pair-matched study was conducted, including patients undergoing tenolysis for flexor tendon adhesion after primary repair of isolated superficial and deep flexor tendon injury and both finger nerves (test group [TG]). These were compared with patients (control group [CG]) with similar injuries without affection of nerves and pair-matched in age, zone of injury and follow-up. Patients' demographics, finger sensitivity, total active range of motion (TAM) before and after tenolysis and complications were retrieved.
RESULTS
For both study groups, 10 patients each were included in this study. There were no significant differences regarding patients' demographics and follow-up. Mean follow-up was 37 (CG) and 41 (TG) months. Total active range of motion was preoperatively 81 ± 47° (CG) and 68 ± 54° (TG) and reached postoperatively 125 ± 57° (CG) and 79 ± 43° (TG). Hence, TAM improvement was significantly higher in patients without nerve damage (58 ± 16 vs 21 ± 11%; P > 0.05). Tendon ruptures occurred significantly more frequent in patients with nerve injury (n = 0.4 ± 0.52) compared with patients of the CG (n = 0; P < 0.05).
CONCLUSIONS
This study shows that finger nerve injury with incomplete recovery after combined flexor tendon and nerve injuries of the finger negatively influences the outcomes of flexor tendon tenolysis.
