Simultaneous paralysis of the ulnar, median and radial nerves is seen in about 1% of hands with nerve involvement in Hansen's disease. Forty such cases were treated between 1955 and 1976; 35 of these have been followed up. In two hands there was a high radial, median and ulnar palsy and these left no scope for reconstruction. The other 33 cases which underwent two-stage reconstructive surgery are presented here. The first stage consisted of restoring active extension of the wrist, fingers and thumb: for this purpose the ideal muscles for transfer are pronator teres, flexor carpi radialis and palmaris longus respectively, and muscle power exceeding Grade 3 (on the
MRC
classification) was achieved in 89%, 96%, and 100% of these individual transfers.
Arthrodesis
of the wrist is not recommended when suitable muscles are available for transfer. The second stage of reconstruction attempts to restore intrinsic function of the fingers and opposition of the thumb; the sublimis is ideal for both purposes and satisfactory restoration of function was achieved in 89% and 85% of cases respectively. Ten of the 18 hands in which all five tendons were transferred had good or excellent results.

Peroneal nerve palsy with resultant foot drop has significant impacts on gait and quality of life. Traditional management includes ankle-foot-orthosis, tendon transfer, and
arthrodesis
-each with certain disadvantages. While nerve transfers for peroneal nerve injury have been reported in adults, with variable results, they have not been described in the pediatric population. We report the use of partial tibial nerve transfer for foot drop from deep peroneal nerve palsy in three pediatric patients. The first sustained a partial common peroneal nerve laceration and underwent transfer of a single tibial nerve branch to deep peroneal nerve 7 months after injury. Robust extensor hallucis longus and extensor digitorum longus reinnervation was obtained without satisfactory tibialis anterior function. The next patient sustained a thigh laceration with partial sciatic nerve injury and underwent transfer of two tibial nerve branches directly to the tibialis anterior component of deep peroneal nerve 9 months after injury. The final patient sustained a blast injury to the posterior knee and similarly underwent a double fascicular transfer directly to tibialis anterior 4 months after injury. The latter two patients obtained sufficient strength (
MRC
4-5) at 1 year to discontinue orthosis. In all patients, we used flexor hallucis longus and/or flexor digitorum longus branches as donors without postoperative loss of toe flexion. Overall, our experience suggests that early double fascicular transfer to an isolated tibialis anterior target, combined with decompression, could produce robust innervation. Further study and collaboration are needed to devise new ways to treat lower extremity nerve palsies.
