This paper begins with a discussion of purely clinical considerations concerning fractures of hip prosthesis shafts, based on findings in 19 cases treated in the University Orthopedic Clinics of Essen and Lübeck. A gradual increase in pain following stress is the principal symptom, although acute pain is not typical. In radiological diagnosis, which is indispensable, the fractures, which are initially often merely hairline cracks, must be looked for. In the patient collective analyzed, the high percentage of implantation defects was striking; this is a factor which increases the risk of fracture because it leads to loosening of the prosthesis. The authors also report on a materials investigation carried out on 18 broken prosthesis shafts. The investigation revealed that in the majority of cases loosening of the prosthesis was the decisive factor leading to the fracture; only in 3 cases was the fracture basically attributable to a fault in the material or in production.
本文基于埃森和吕贝克大学骨科诊所治疗的19例病例的研究结果，首先讨论了关于髋关节假体柄骨折的纯临床考量因素。尽管急性疼痛并不典型，但应力作用后疼痛逐渐加剧是主要症状。在不可或缺的放射学诊断中，必须查找起初往往只是细微裂缝的骨折。在所分析的患者群体中，植入缺陷的高比例令人瞩目；这是一个增加骨折风险的因素，因为它会导致假体松动。作者还报告了对18根断裂假体柄进行的材料调查。调查显示，在大多数情况下，假体松动是导致骨折的决定性因素；只有3例骨折基本上可归因于材料或生产中的缺陷。
