Stress fractures of the tibia secondary to tibial deformities from osteoarthritis are rare, and may be difficult to manage. We treated two patients with stress fractures of the proximal tibial diaphyses over a period of two years. Both patients had osteoarthritis of the knee; one with genu valgus deformity and the other, genu varus deformity. The former patient also had a distal tibial fracture and had previously undergone open reduction and internal fixation. The stress fractures of both the patients had been treated conservatively by nonoperative means, but their fractures failed to unite. They then underwent a modular total knee prosthesis with a long tibial stem extension, and subsequently, their fractures united. Both patients recovered uneventfully.
由于骨关节炎导致的胫骨畸形而继发的胫骨应力性骨折较为少见，且可能难以处理。我们在两年时间里治疗了 2 例胫骨骨干近端应力性骨折患者。这 2 例患者均患有膝关节骨关节炎；其中 1 例存在膝外翻畸形，另 1 例存在膝内翻畸形。前者患者还存在胫骨远端骨折，曾行切开复位内固定术。这 2 例患者的应力性骨折均经非手术方法保守治疗，但骨折均未愈合。随后，他们接受了带长胫骨干延伸段的模块化全膝关节假体治疗，此后骨折愈合。这 2 例患者均恢复顺利。
