Disability and Quality of Life after Talectomy for Arthrogryposis Multiplex Congenita

BACKGROUND:Arthrogryposis multiplex congenita (AMC) is one of the causes of rigid and resistant clubfoot. Talectomy is considered as a primary or salvage procedure for recurrent equinovarus deformity in these patients. We conducted this study to assess patients with AMC who underwent talectomy for the correction of foot and ankle deformities in terms of health-related quality of life and disability.METHODS:Patients under 10 years of age with a primary diagnosis of AMC who underwent talectomy and attended follow-up for at least 5 years were included in this study. We also formed an age- and gender-matched control group consisting of 20 individuals without any foot-ankle problem in order to compare the measurements between the AMC and healthy groups. Oxford Ankle Foot Questionnaire (OxAFQ) was administered as a health-related quality of life instrument to objectively measure the disability of the pediatric patients.RESULTS:Twenty patients (10 girls, 10 boys) who underwent a total of 35 talectomy operations with an average follow-up of 7.2 years and a control group of 20 similarly aged unaffected children were included in the study. The mean OxAFQ scores were significantly lower in the AMC group than in the controls for all domains (physical, emotional, and school and play), especially for the one concerning satisfaction with footwear The presence of plantigrade foot and absence of forefoot supination were significantly associated with the physical and footwear domains of the OxAFQ scores. The presence of hindfoot varus, midfoot adductus, dorsal bunion, and having less than 10 degrees of dorsiflexion had no effect on the OxAFQ scores.CONCLUSION:In this study, we found that the major driving factors for satisfaction after talectomy for AMC were plantigrade foot and absence of forefoot supination. The mean OxAFQ scores were universally lower in the AMC group than controls. Finding comfortable footwear is a major concern for the AMC patients.LEVEL OF EVIDENCE:Level III, retrospective cohort study.
