WebMethods: We evaluated the first 361 consecutive hip resurfacings performed by a single surgeon, which had a mean follow-up of 59 months (range, 28 to 87 months). Pre and post-operative radiographs were assessed to determine the inclination of the acetabular component, as well as the sagittal and coronal femoral stem-neck angles. WebTwo types of prostheses are in current use. Unipolar hip prostheses consist of a femoral stem with a fixed (monolithic) or modular head that articulates with the native acetabular …
