Patients with sickle cell hemoglobinopathies often have femoral head osteonecrosis with collapse, and can benefit greatly from total hip arthroplasty. However, numerous procedural challenges and perioperative complications make these cases difficult. More specifically, femoral canal preparation and proper component placement can be particularly challenging due to focal medullary sclerosis caused by repeated vascular insults to the bone. This study describes the creation of an anterior metaphyseal cortical bone window to aid in identification of the true femoral canal and to facilitate femoral component implantation.
镰状细胞血红蛋白病患者常伴有股骨头坏死和塌陷，全髋关节置换术可使他们受益。然而，由于反复的血管损伤导致骨髓腔局灶性硬化，这些病例在手术过程中会遇到许多程序上的挑战和围手术期并发症，使得手术难度加大。更具体地说，由于反复的血管损伤导致骨髓腔局灶性硬化，股骨髓腔的准备和合适的假体放置会特别具有挑战性。本研究描述了一种前侧干骺端皮质骨窗的创建方法，以帮助识别真正的股骨髓腔，并促进股骨假体的植入。
