本研究應用Pedar in-sole壓力量測系統來分析大腳趾外翻病人接受Mitchell矯正切骨手術的足底壓力變化,並與未接受手術側足做比較。總共12個病人接受測量,從接受手術到接受測量期間平均是7.67個月(2個月〜27個月),受測者平均年齡是48歲(20歲〜65歲)。結果顯示手術側足在平路行走時有支撐時間增加現象,足底接觸面積則與未手術側相似,接受手術側足之足底壓力顯示峰值壓力、最大峰值壓力、壓力-時間乘積和力量-時間乘積在後足和中足外側都有明顯增加,在前足與足趾壓力變化則有相反的結果,這顯示出大腳趾外翻病人在接受Mitchell矯正切骨手術平均7.67個月後,足底壓力在後足部與足部外側有增加情形。經過大腳趾外翻矯正手術後,大部份患者蹠骨部位的峰值壓力出現在第二和第三蹠骨頭處,此情形則與正常足類似。
The purpose of this study was to employ a Pedar in-sole pressure system to identify the foot pressure distribution after Mitchell osteotomy for hallux valgus, and to find out the changes after surgery through comparing foot pressure in the affected side of patients with those in the unaffected side during level walking. Twelve patients who had a Mitchell procedure to correct hallux valgus deformities were examined with foot pressure measurement system at an average of 7.67 months (range, two to twenty-seven months) after the operation. The average age of the patients was forty-eight years (range, twenty to sixty-five years). The result showed that an increase in supporting time in feet with hallux valgus during walking. The contact areas of feet with hallux valgus were similar with the normal feet. In feet with hallux valgus, peak pressures, maximum peak pressure, pressure-time integrals and force-time integrals under the hindfoot and lateral midfoot had a significant increase. Inverse results shown in forefoot and toes. It meant the hallux valgus foot for average of 7.67 months follow up after Mitchell osteotomy bears higher load on the hindfoot and lateral midfoot regions. After osteotomy correction of the hallux valgus, the peak pressures under the metatarsal heads were observed in the second and third metatarsal heads in most cases. They were similar with the normal feet.
