In two years we treated four women with ununited stress fractures of their proximal tibial diaphyses. They all had arthritis and valgus deformity. The stress fractures had been treated elsewhere by non-operative means in three patients and by open reduction and internal fixation in one, but had failed to unite. After treatment with a modular total knee prosthesis with a long tibial stem extension, all the fractures united. A modular total knee prosthesis is suitable for the rare and difficult problem of ununited tibial stress fractures in patients with deformed arthritic knees since it corrects the deformity and the adverse biomechanics at the fracture site, stabilises the fracture and treats the arthritis.
在两年时间里，我们治疗了4例胫骨近端骨干应力性骨折不愈合的女性患者。她们均有关节炎和外翻畸形。其中3例患者的应力性骨折在其他地方接受了非手术治疗，1例接受了切开复位内固定治疗，但均未愈合。使用带有长胫骨柄延伸的模块化全膝关节假体治疗后，所有骨折均愈合。模块化全膝关节假体适用于畸形关节炎膝关节患者罕见且棘手的胫骨应力性骨折不愈合问题，因为它能纠正畸形和骨折部位的不良生物力学状况，稳定骨折并治疗关节炎。
