Abstract
Fully porous-coated cementless implants have a low failure rate and excellent survivorship in primary and revision surgery. Failure secondary to implant fracture is extremely rare with modern implant designs. We report an early fracture of a fully porous-coated femoral stem after primary total hip arthroplasty. The implant failed because of a filling mismatch between the proximal and distal femur.
摘要
全多孔涂层非骨水泥植入物在初次手术和翻修手术中具有较低的失败率和优异的存活率。在现代植入物设计中，由于植入物断裂导致的失败极为罕见。我们报告了初次全髋关节置换术后全多孔涂层股骨柄的早期断裂。该植入物失败的原因是股骨近端和远端之间的填充不匹配。
