The Value of the Direct Lateral Hip Radiograph in an Adult Reconstruction PracticeThe specialty evaluation of hip pain, stiffness, and/or dysfunction usually includes patient history, physical examination, and radiographic evaluation. Radiographic views of the hip are not standardized, and basic studies may include an anteroposterior pelvis, anteroposterior hip, frog lateral, and direct lateral of the hip. In this article, we discuss the importance of obtaining a direct lateral radiograph of the hip in all patients being evaluated by a specialist for hip pain and its value in hip arthroplasty care.
Custom titanium sleeve for surgical treatment of mechanically assisted crevice corrosion in the well-fixed, noncontemporary stem in total hip arthroplastyAdverse local tissue reaction associated with total hip replacement may occur when mechanically assisted crevice corrosion occurs at metal-metal modular junctions in which at least one of the components is fabricated from cobalt-chromium alloy. Complete removal of components may be associated with significant morbidity; when components are well fixed and in acceptable position, it may be appropriate to consider modular rather than complete revision. We have diagnosed mechanically assisted crevice corrosion in total hip arthroplasty patients with noncontemporary but well-fixed femoral components and found that modular conversion to a ceramic femoral head to remove a source of CoCr corrosion and fretting products was only possible by having a custom titanium sleeve manufactured.
