BACKGROUND: @entity3030 result in tibialis anterior muscle @entity912 and associated loss of ankle dorsiflexion. Nerve grafting of peroneal nerve injuries has led to poor function; therefore, tendon transfers and ankle-foot orthotics have been the standard treatment for foot drop. QUESTIONS/PURPOSES: We (1) describe an alternative surgical technique to obtain ankle dorsiflexion by partial tibial nerve transfer to the motor branch of the tibialis anterior muscle; (2) evaluate ankle dorsiflexion strength using British Medical Research Council grading after nerve transfer; and (3) qualitatively determine factors that influence functional success of surgery. METHODS: We retrospectively reviewed 11 @entity1 treated with partial tibial nerve transfers after @entity3030 . Pre- and postoperative motor strength was measured. @entity1 completed questionnaires regarding pre- and postoperative gait and disability. RESULTS: One @entity1 regained Grade 4 ankle dorsiflexion, three @entity1 regained Grade 3, one @entity1 regained Grade 2, and two @entity1 regained Grade 1 ankle dorsiflexion. Four @entity1 did not regain any muscle activity. Clinically apparent motor recovery occurred an average 7.6 months postoperatively. A majority of @entity1 (nine) could walk and participate in activities. Seven @entity1 did not wear ankle-foot orthotics and four @entity1 did not limp. The donor deficits included weak toe flexion (two @entity1 ) and reduced @entity291 circumference (seven @entity1 ). CONCLUSION: Our observations suggest nerve transfers to the deep peroneal nerve provide inconsistent ankle dorsiflexion strength, possibly related to the mechanism of @entity3030 or delays in surgery. Despite variable strength, four @entity1 achieved M3 or greater motor recovery, which enabled them to walk without assistive devices. LEVEL OF EVIDENCE: Level IV, therapeutic study. See Guidelines for Authors for a complete description of levels of evidence.
