Correction of ulnar claw hand by a loop of flexor digitorum superficialis motor for lumbrical replacement

The current dynamic procedures for correction of ulnar claw hand are extensor carpi radialis longus many tail graft, palmaris longus four finger many tail graft and extensor by pass operation. Each of these procedures takes a minimum of one and a half hours and needs extensive post operative re-education and training. These procedures employ a graft of plantaris tendon, fascia lata or extensor tendon, with the disadvantages of operating at another site and adhesion of grafts. The procedure described in this article obviates these disadvantages. The operation is simple to perform and has given good results even when performed at leprosy camps where no extensive re-education physiotherapy was available. This operation also tends to correct the reversal of transverse arch. The technique and observations are discussed in detail.
