Abstract: ［Abstract］〓Objective〖HTSS〗〓To investigate the clinical effect of homemade external fixator in the treatment of multiple metatarsal and phalangeal head fractures.
〖HTH〗〖WTHZ〗Methods〖HTSS〗〓 A total of 150 cases patient with multiple metatarsal and phalangeal head fractures were selected. They were divided randomly into external fixation group(homemade external fixator fixation) and internal fixation group(conventional open reduction and internal fixation), each with 75 cases. The surgical effect, toe deformity, stump trimming rates and postoperative complications were compared.
〖HTH〗〖WTHZ〗Results〖HTSS〗〓All the patients underwent the operation successfully, and were followed up for 3-12 months. The time of hospitalization and fracture healing in the external fixation group was significantly shorter than that in the internal fixation group, and the cost of treatment was lower than that in the internal fixation group. The difference was statistically significant(P＜005). There were no significant statistical differences in operation time(P＞005). The clinical efficacy for the external fixation group is superior to the internal fixation group, with significantly higher good rate and lower deformity and stump trimming rates. The differences were statistically significant(P＜005). The postoperative complications in the external fixation group is significantly lower than that in the internal fixation group, and the difference was statistically significant(P＜005).
〖HTH〗〖WTHZ〗Conclusion〖HTSS〗〓Homemade external fixator has significant effect and higher safety in the treatment of multiple metatarsal and phalangeal head fractures.
