Objective : To report on preoperative outcomes that guide the selection of surgical techniques to correct equinovarus foot (EVF) in brain-injured adults.
 

Material / Patients and Methods : A search strategy was conducted on 4 databases (Pubmed, Medline, Cochrane, PEDro) until July, 2021, according to the PRISMA guidelines. Studies were included regardless of their level of evidence.

Results : Sixty-one studies (n=2,293 participants) were analyzed and concerned neurotomies (n=523), calf lengthening (n=437), tibialis anterior (TA) transfer (n=888) or alternative transfers with the flexor digitorum/hallucis longus (n=249), the extensor hallucis longus (n=102), the tibialis posterior (n=41), the peroneus longus (n=41) and osteoarticular surgeries (n=12). 
Passive ankle dorsiflexion was assessed before 87% of neurotomy studies, among which there was 62% of non-retracted spastic EVF. Ankle dorsiflexors motricity was assessed before 70% of neurotomies compared to 29% before isolated calf lengthening studies, their strength being at least 3/5 in respectively 33% and 50% of the studies concerned.
Before anterior tendon transfer with the TA or another muscle, passive ankle dorsiflexion was only reported in 20% and 46% of the studies and dynamic TA activation during gait in 46% and 56% of the studies, respectively.
The correction of varus justified the TA transfer in 60% of the studies, often independently of its function, compared to 30% in other transfers which were justified by hyperactivity or voluntary recruitment of transferred muscle.

 

Discussion - Conclusion : This work highlights the lack of formal data to rationally guide the choice of the most appropriate surgical technique in the management of EVF and reinforces the interest of a systematic standardized preoperative assessment.
