Pins and locking screws found in modular PE spacers should be removed before extraction. An osteotome or saw can also be used to divide the PE insert if needed for easier removal ( Video 21.2).46,49 Page 182Femoral component Femoral component removal occurs at the implant–bone

bone resorption and repair occur, leading to loss of structural integrity, collapse, and subchondral failure.3,4 In this chapter, we discuss the different etiologies of ONFH, diagnosis and classification systems, nonoperative management, indications for total hip arthroplasty (THA) in the setting of ONFH, and explore

bone loss, osteolysis, and implant alignment. It can also be useful to compare with prefracture radiographs when available.32 Comparing prefracture and postfracture radiographs may allow for detection of implant loosening. Implant loosening can be identified on radiographs through presence of changes in implant alignment, radiolucency

nails have been shown to be sufficient for stabilization. Distal metaphyseal lesions are less common and, depending on the size and amount of bone

Bone scintigraphy and magnetic resonance imaging (MRI) are costly and nonspecific and are not recommended as part of the routine workup of PJI in a patient with a painful THA. Serum biomarkers are a widely available and less invasive means by which surgeons can screen

bone quality of the proximal femur.9,10 Once a patient has been indicated as a reasonable candidate for THA, the surgeon must decide which approach, implants, and technology will be used during the procedure. Approaches Three mainstay approaches predominate for primary THA: direct anterior (Heuter
