The preliminary results based on a three year retrospective study in cavus foot deformity of forty-four Friedreich ataxia patients regularly seen at the Neuromuscular Disease Clinic of Sainte-Justine Hospital have been presented. An accurate "weight-bearing" foot stereoradiographic technique has been recently developed by our group. Since the follow-up period with this device is not sufficient to provide statistical information, the conventional non-weight bearing technique has been utilized in this study to enable a possible comparison between the radiographs of ambulant and non-ambulant patients. Due to the present technique, the results of this study must be interpreted with caution. For 132 pairs of radiographs, 28 parameters have been analyzed. Four of these, namely the calcaneal inclination angle, the first metatarsal inclination angle, the inferior cortex of calcaneus-first metatarsal angle and the first-fifth metatarsals angle, were of particular interest. From these parameters, a preliminary quantitative description of cavus foot deformity in Friedreich's ataxia has been attempted. Three stages of evolution have been tentatively identified for this type of neurological disorder.
本文展示了一项针对44名弗里德赖希共济失调患者足内翻畸形的为期三年的回顾性研究初步结果，这些患者均定期就诊于圣贾斯汀医院神经肌肉疾病诊所。我们团队最近开发了一种精确的“负重”足部立体放射成像技术。由于使用该设备的随访期不足以提供统计信息，本研究采用了传统的非负重技术，以便对能行走和不能行走患者的X光片进行比较。基于目前的技术，本研究结果的解读必须谨慎。对132对X光片分析了28个参数。其中四个参数，即跟骨倾斜角、第一跖骨倾斜角、跟骨-第一跖骨下角和第一-第五跖骨角，尤其令人关注。基于这些参数，尝试对弗里德赖希共济失调中的足内翻畸形进行初步定量描述。对于这类神经系统疾病，初步确定了三个演变阶段。
