Neuro-Orthopedic Surgery for Equinovarus Foot Deformity in Adults: A Narrative Review.

Abstract

Neuro-orthopedic surgery is an alternative to the conservative treatment of spastic equinovarus foot (SEF) in adults. The objective of the present narrative review was to summarize current practice with regard to patient assessment, the choice of treatment, the various neuro-orthopedic procedures, and the latter's outcomes. We searched literature databases (MEDLINE, EMBASE, Cochrane) for original articles or opinion papers on surgical treatment of spastic equinovarus foot in adults. Neuro-orthopedic approaches require a careful analysis of the patient's and/or his/her caregiver needs and thus relevant treatment goals. Surgical planning requires detailed knowledge of impairments involved in the spastic equinovarus foot deformity based on a careful clinical examination and additional information from diagnostic nerve blocks and/or a quantitative gait analysis. Procedures mainly target nerves (neurotomy) and tendons (lengthening, transfer, tenotomy). These procedures reduce impairments (spasticity, range of motion, and foot position), improve gait and walking function, but their impact on participation and personalized treatment goals remains to be demonstrated. Neuro-orthopedic surgery is an effective treatment option for spastic equinovarus foot in adults. However, practice is still very heterogeneous and there is no consensus on the medical strategies to be applied before, during and after surgery (particularly the type of anesthesia, the need for immobilization, rehabilitation procedures).
