Abstract
Despite extensive study of the anatomical and functional aspects of finger flexor tendon repair, as well as the development of more advanced implants for their reconstruction, injuries to these structures remain a major orthopedic problem. Finger flexor tendon injuries are a common pathology, accounting for approximately 38% of all hand injuries, according to Russian publications. Finger flexor tendon repair in the fibrosynovial canal zone, which corresponds to zone 2 according to the Verdan classification, is currently an open debate. The choice of surgical treatment has remained relevant for several decades due to the close interrelationships between the anatomical structures in the injury zone, the tendency of the sliding tendon apparatus to form adhesions within the fibrosynovial canal, and the need for early rehabilitation measures, which increases the risk of tendon suture rupture or failure of the reconstructed annular ligaments. Currently, the main methods for repairing finger flexor tendon injuries are primary suturing and single-stage tendoplasty. However, there are controversies regarding the surgical approach for treating patients with second-stage finger flexor tendon injuries.
