Total hip arthroplasty has become one of the most succesful procedure in orthopaedic surgery. More and more active, young patients undergo primary hip replacement. Bone stock preservation is crucial when performing THR in this group of patients. The short stem design allows a methaphyseal intratrochanteric multipoint, strong primary fixation which is very important for this group of patients. The goal is to save bone stock for the revision operation. This study presents early results of Metha short stems prosthesis. Between April 2006-December 2007, 58 short stem (Metha) were implanted. The Harris Hip Score improved from a mean 64.3 before to 89.7 at follow-up. The Metha stem may not be indicated for every hip diseases. There were only two fractures of femur without any further problems. Despite the short follow-up, Metha prosthesis already represent a valuable alternative for younger patients.
全髋关节置换术已成为骨科手术中最成功的手术之一。越来越多活跃的年轻患者接受初次髋关节置换。对于这类患者进行全髋关节置换时，保留骨量至关重要。短柄设计允许在干骺端粗隆内进行多点、牢固的初次固定，这对这类患者非常重要。目标是为翻修手术保留骨量。本研究展示了Metha短柄假体的早期结果。在2006年4月至2007年12月期间，植入了58个短柄（Metha）假体。Harris髋关节评分从术前平均64.3提高到随访时的89.7。Metha柄可能并非适用于所有髋关节疾病。仅发生了两例股骨骨折，未出现任何其他问题。尽管随访时间较短，但Metha假体已成为年轻患者的一种有价值的替代选择。
