Comparison of Two Different Fixation in Adolescent Hallux Valgus Osteotomy

Abstract：Objective To compare the fixation effects of Kirschner and bone plate in metatarsal osteotomy in adolescent hallux valgus. Methods There were 23 adolescent hallux valgus patients(40 feet). The cases were divided into group A and group B by different internal fixation methods. Group A were fixed with Kirschner wire,group B were fixed with plate. We took weight-bearring foot anteroposterior and lateral X-ray film before and after operation and in the last follow-up. We also meas-ured the HVA and 1 ~ 2 IMA,assessed the function by the AOFAS hallux metatarsophalangeal joint,interphalangeal joint score,and recorded concurrently disease occurrence,assessed the patient final follow-up function by comparing the hallux val-gus angle(HVA)and 1 ~ 2 metatarsal angle(IMA)and AOFAS score in preoperative exam,postoperative exam and final fol-low-up. SPSS 19. 0 was used to do the statistics. Results Statistical analysis showed that there was no significantly different in the Kirschner wire group and the plate group in HVA(P = 0. 565),IMA(P = 0. 911)and AOFAS(P = 0. 818). And in both groups'HVA(P = 0. 737 ),IMA(P = 0. 453)had no significantly different one day after operation. The Kirschner group and the plate group HVA(P ﹤ 0. 05),IMA(P ﹤ 0. 051)and AOFAS(P ﹤ 0. 05)were significantly different one year after the oper-ation. Conclusion The Kirschner group and the plate group are not significantly different in a short term after the operation, but significantly different after one year. That means the plate is better than Kirschner wire.
