Abstract

Objective: To report a new surgical technique and the comparative clinical outcomes in patients with primary tenorrhaphy rupture or chronic flexor digitorum profundus (FDP) injuries in Verdan zones I and II, treated with non-conventional tendon advancement.Materials and Methods: The study population consisted of 13 patients over 18 years (averaging 29 years) who had had injuries in Verdan zones I and II and at least a 36-month follow-up. Patients were divided into two groups according to injury type (7 cases of primary tenorrhaphy rupture and 6 cases of chronic FDP injuries) and surgical technique (Z-plasty lengthening plus end-to-end suture or lateral suture to an adjacent undamaged FDP tendon at zone-V level, respectively). The results were evaluated according to Strickland’s scoring system.
Results: The average follow-up was 51 months. Time period between injury and surgery averaged 11.7 weeks (range, 2-24 weeks). Strickland scoring system results: excellent in 8 patients, good in 4 patients, and poor in 1 patient. Study average tendon advancement was 20.5mm.
Conclusions: Non-conventional tendon advancement for primary tenorrhaphy ruptures or chronic FDP injuries in Verdan zones I and II proved to be a reproducible and effective treatment.
Key words: Tendon; flexor; lengthening; Z-plasty.Level of Evidence: III
