Injury and Section of Flexors in Zone II

Flexor tendon repair is a challenging task in hand surgery, with numerous studies and publications on the subject. The incidence of flexor tendon injuries in India is estimated to be around 14/100,000-person years. The fingers are characterized by five zones: Zone I, Zone II, Zone III, Zone IV, and Zone V. Reparation of these zones involves flap extension, suturing, and band repair. However, tendon repair is fraught with complications, with the most catastrophic outcome being rupture. Tendon adhesions are a common consequence of the healing process and can be limited with atraumatic surgical techniques, robust repair, and early mobilization strategies. Ultrasound imaging is helpful in determining the continuity of the flexor tendon. Tenolysis surgery may be necessary if treatment is unsuccessful, but is generally recommended after three to six months.
