Fracture of calcaneum following drop foot surgery--a case report.

The usual protocol for correction of drop foot in leprosy, a consequence of damage to the common peroneal nerve, is a tendon transfer, immobilisation to heal the tendon juncture and post-operative exercises to put the transfer into use. Tarsal disintegrations have been reported in literature in drop foot patients when the transferred tendons were inserted into the bone making a drill hole to ensure firm anchorage. Such disintegrations are rarely seen these days because bony insertion of the tendon transfers is not performed in the leprosy-affected foot. We report here a case of drop foot that developed a fracture of the calcaneum during the post-operative period after tibialis posterior two tail transfer (to tibialis anterior and extensor digitorum longus) along with lengthening of the tendoachillis. The case is interesting in the sense that osteoporosis and walking strains resulted in a fracture of the body of the calcaneum which healed with conservative treatment and controlled mobilisation of the patient.

ECRL--a wrist extensor with multiple uses in deformity correction.

Extensor carpi radialis longus muscle has been used in various types of procedures for corrective hand surgery and is a favored muscle for correction of finger clawing due to ulnar nerve palsy in leprosy because its removal leaves an insignificant motor deficit and gives a linear scar at the donor site. It is usually not paralyzed in leprosy. The muscle, being phasic, is easy to re-educate. The excursion of the muscle is similar to lumbrical muscles which it substitutes. Since the muscle is dorsally located, the transfer does not lose tension due to adaptive wrist flexing habit. Its tendon is usually thick enough, can be split into two and used as graft to elongate the muscle-tendon unit or for ligament reconstruction in cases of trapezio-metacarpal joint arthritis.
