Trochanteric osteotomy is commonly performed during total hip arthroplasty. Subsequent fatigue fracture of the osteotomy wires, although common, usually has no clinical sequelae. In four cases, wire fragments migrated down the medullary cavity of the femur, in the space created by a loosened femoral component. This roentgenographic observation seems not to have been previously reported and is a definitive sign of femoral prosthesis loosening.
转子截骨术通常在全髋关节置换术中进行。截骨钢丝随后发生疲劳骨折,虽然常见,但通常没有临床后遗症。在4例病例中,钢丝碎片在股骨假体松动所形成的间隙中向股骨骨髓腔内迁移。这种影像学表现似乎此前未见报道,是股骨假体松动的确切征象。
