BACKGROUND Symptomatic labral tears of the hip are associated with bony abnormalities of the femoral head and acetabulum, resulting in impingement. These patients have characteristic internal rotation limitations, which can result in compensatory athletic injury patterns around the hip, pelvis, and lumbar spine. HYPOTHESIS Patients undergoing arthroscopic cam decompression will have improveme...

We present a new CT-based method which measures cover of the femoral head in both normal and dysplastic hips and allows assessment of acetabular inclination and anteversion. A clear topographical image of the head with its covered area is generated. We studied 36 normal and 39 dysplastic hips. In the normal hips the mean cover was 73% (66% to 81%), whereas in the dysplastic group it was 51% (38...

BACKGROUND During total hip arthroplasty, use of a modular femoral neck on a stemmed implant allows optimization of neck anteversion, length, and offset, resulting in more accurate balance. We performed a retrospective analysis of a consecutive cohort of patients who had undergone total hip arthroplasty with a modular-neck hip system with ceramic-on-ceramic bearings. METHODS We reviewed the r...

PURPOSE OF THE STUDY This study aims to ascertain whether a high anteversion of the femoral neck can influence measurement caputcollum-diaphyseal (CCD) angle on plain anteroposterior (AP) radiograph proximal femur. MATERIAL AND METHODS We developed new method measuring CCD and version was done with use computer program that utilised entire visualised area shaft calculate their long axis. Using ...

BACKGROUND Acetabular component malposition is linked to higher bearing surface wear and component instability. Outcomes following total hip arthroplasty and surface replacement arthroplasty depend on multiple surgeon and patient-dependent factors. The purpose of this study was to examine the frequency in which acetabular components are placed within a predetermined target range. METHODS We e...
