The correction of ulnar claw fingers: a follow-up study comparing the extensor-to-flexor with the palmaris longus 4-tailed tendon transfer in patients with leprosy

Zancolli procedure and nerve repair with sural graft as a treatment for patient with claw hand due to complete rupture of ulnar and median nerve: A case report

“…In our center, there were several cases of ulnar nerve palsy due to leprosy that underwent FDS tendon transfer to A1 pulley, that is, Zancolli-lasso procedure [ 9 ]. In those cases, The FDS tendon is harvested and wrapped distally around the A1 pulley.…”

A Review of the Biomechanics of Intrinsic Replacement in Ulnar Palsy

“…1 Small finger: abductor digiti and flexor digiti minimi have some flexor moment on the 5th MCP joint. require a stronger muscle (Duerksen and Schwarz, 2004;Fritschi, 1984;Taylor et al, 2004), although the actual strength required for different types of hands has not been determined in a quantifiable way. However, none of the potential donors have the strength of the combined intrinsic muscles of the four fingers; yet clinical results are very good with most of the transfers in an experienced surgeon's hands.…”

The surgical management of deformities of the hand in leprosy

“…21,42 In a recent article on the correction obtained on unspecified types of claw hand in leprosy, excellent to fair results were achieved in 92% using the extensor-to-flexor four-tailed transfer, and similar results with the palmaris longus four-tailed transfer both of which were transferred to the insertion of the lateral band. 43 Harvesting of the superficialis tendon through the lateral approach gave rise to flexion contractures of the proximal interphalangeal (PIP) joints, distal interphalangeal (DIP) extension lag in the donor finger, a high incidence of swanneck deformity, a 'superficialis-minus' deformity, and loss of flexion of the PIP joint. 15,18,19,42,44 These problems have been lessened by harvesting the FDS tendon through the proximal pulley systems.…”
