The aim of this study was to determine how effective forefoot arthroplasty is at reducing the pressures under the forefoot. The EMED F pressure measuring system was used. Fifteen patients (23 feet) were included in the study. All patients had foot pressure studies performed before and after surgery. Our results show a significant increase in total pressure and pressure-time integral under the foot after surgery. This increase was most marked under the first metatarsal head region (P < .005). However, the midmetatarsal region showed a slight decrease in pressure, but this was not significant. Symptomatically, 13 patients felt improved by the operation. The results suggest that the procedure is successful because it transfers the pressure to areas better able to tolerate it, rather than reduces the total pressure.
本研究的目的是确定前足关节成形术在减轻前足压力方面的效果如何。使用了EMED F压力测量系统。15名患者（23只脚）纳入了本研究。所有患者在手术前后均进行了足部压力研究。我们的结果显示，术后足部的总压力和压力-时间积分显著增加。这种增加在第一跖骨头区域最为明显（P <.005）。然而，跖骨中部区域的压力略有下降，但不显著。从症状方面来看，13名患者术后感觉有所改善。结果表明，该手术是成功的，因为它将压力转移到了更能耐受压力的区域，而不是降低了总压力。
