Gait Analysis and Functional Outcome After Calcaneal XXXX .

@entity1 @entity174
BACKGROUND: Calcaneal @entity174 are associated with substantial morbidity and socioeconomic impact, frequently leading to limited functional outcome and high economic costs. The Oxford foot model (OFM) has been reported as a valid addition to the biomechanical examination of the foot. The aim of our study was to analyze the gait of @entity1 after operative repair of a calcaneal @entity174 in relation to functional outcome and radiographic findings. METHODS: Thirteen @entity1 with a calcaneal @entity174 underwent gait analysis with OFM at a minimum of six months after open surgery. Intersegmental range of motion was measured during gait. Results were compared with those of healthy subjects and those of @entity1 who had undergone subtalar arthrodesis. @entity1 -reported questionnaires and radiographic images were also evaluated. RESULTS: The range of motion between the hindfoot and the tibia in the push-off phase in the transverse plane was significantly correlated with the clinical outcome as reported by @entity1 based on the Foot and Ankle Disability Index (FADI) (r(2) = 0.51; p < 0.001) and the Short Form (SF)-36 physical component summary score (r(2) = 0.52; p < 0.001). We found a significant correlation between the step-off in the subtalar joint as measured on postoperative computed tomography (CT) and range of motion (r(2) = -0.74; p = 0.004). The step-off was also correlated with the @entity1 -reported outcome questionnaire FADI (r(2) = -0.76; p = 0.003) and the SF-36 physical component summary score (r(2) = -0.78; p = 0.002). CONCLUSIONS: This study demonstrated that the subtalar joint range of motion of @entity1 after a calcaneal @entity174 was related both to the quality of the reduction of the subtalar joint as evaluated on postoperative CT scans and @entity1 -reported functional outcome. LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.
