Short stem hip replacement has not only gained attention but also significance over the past decades. However, there still remains uncertainty regarding the correct indications for these stems. Even companies, producing implants, have varying recommendations that are more likely based on a well-meant advice than on statistically evaluated data. Thus, it is important to evaluate the advantages and disadvantages of a short stem prosthesis. The goal of this paper is to reveal some of the existing uncertainty in this field, by analyzing the Metha short hip stem system. This paper does not only focus on general aspects but also discusses some more specific problems, such as avascular necrosis and post-rheumatic diseases, as well as hip dysplasia and coxarthrosis. The aim is also to convey the opportunity to indicate this type of implant for elderly and obese patients as well as for femoral misalignments following post-Perthes disease, post-traumatic deformities or other malpositions of the hip.
在过去几十年里，短柄髋关节置换术不仅受到关注，而且具有重要意义。然而，对于这些柄的正确适应证仍存在不确定性。甚至生产植入物的公司也有不同的建议，这些建议更可能基于善意的建议而非经统计学评估的数据。因此，评估短柄假体的优缺点很重要。本文的目的是通过分析梅塔短柄髋关节系统，揭示该领域现有的一些不确定性。本文不仅关注一般方面，还讨论了一些更具体的问题，如缺血性坏死和风湿性疾病后、髋关节发育不良和髋关节炎。目的还在于传达为老年和肥胖患者以及佩特兹病后、创伤后畸形或其他髋关节错位后的股骨排列不齐患者指明这种类型植入物的机会。
