Strickland technique of flexor tendon repair in zone II. A, Knife laceration through zone II with digit in full flexion. B, Level of flexor tendon retraction of same finger after digital extension. C, Green lines depict radial and ulnar incisions to allow wide exposure of flexor tendon system. D, Flexor tendon system of involved finger after reflection of skin flaps. In this case, laceration has occurred through C1 cruciate pulley area. Note proximal and distal position of severed flexor tendon stumps resulting from flexed attitude of finger at time of injury. Green lines indicate lateral incisions in cruciate-synovial portions of sheath, which are used to provide exposure for tendon repair. E, Reflection of small triangular flaps at cruciate-synovial sheath allows distal flexor tendon stumps to be delivered into wound by passive flexion of distal interphalangeal joint. Profundus and sublimis stumps are retrieved proximal to A1 pulley, using small catheter or infant feeding gastrostomy tube. F, Proximal flexor tendon stumps are maintained at repair site by means of transversely placed small-gauge hypodermic needle, followed by repair of flexor digitorum sublimis slips. G, Completed repair of both tendons with distal interphalangeal joint in full flexion. H, Extension of distal interphalangeal joint delivers repair under intact distal flexor tendon sheath. Repair of cruciate (C1)-synovial pulley has been completed. I, Wound repair at conclusion of procedure.
