Retroversion of the adult acetabulum following a previous Legg-Calvé-Perthes disease (LCPD) is found in 30-40% of the patients. It is known that in LCPD there may also be morphologic changes in the nonaffected controlateral acetabulum. We investigated the prevalence of retroversion of the contralateral acetabulum in a group of adult patients with a history of LCPD. We found this morphology in 1...

introduction for decades, acetabular fractures were treated conservatively. judet et al. in 1960s established the operative treatment of these fractures by continuous improvement of pre-operative evaluation and classification of fractures. several studies demonstrated that accurate fracture reduction decreases the incidence of post-traumatic arthritis and improves functional outcome. conclusion...

A few specimens collected from northeast of Iran were identified Helvella acetabulum (L.) Quél.

BACKGROUND Numerous structural deformities of the acetabulum are associated with hip osteoarthritis (OA). Acetabular retroversion has been implicated in the development of femoroacetabular impingement. However, it is unknown if retroversion occurs from isolated excessive bone in the superior acetabulum or a torsional phenomenon of the entire pelvic segment. QUESTIONS/PURPOSES A method was dev...

Biphasic creep indentation methodology and an automated indentation apparatus were used to measure the aggregate modulus, Poisson's ratio, permeability, thickness, creep and recovery equilibrium times, and percentage of recovery of normal articular cartilage in 10 human hip joints. These properties were mapped regionally to examine the mechanical factors involved in the development of site-spec...

a few specimens collected from northeast of iran were identified helvella acetabulum (l.) quél.

PURPOSE Our purpose was to develop an alternative method to divide the acetabulum and femoral head into different zones based on anatomic landmarks clearly visible during arthroscopy to facilitate reporting the geographic location of intra-articular injuries. METHODS Two vertical lines are positioned across the acetabulum aligned with the anterior and posterior limits of the acetabular notch....

Case 1-An agricultural worker, a man of thirty-eight, fell under a tractor, which ran over the inner side of his right thigh causing a backward dislocation of the head of the femur. Radiographs showed what appeared to be a simple posterior dislocation of the hip with a tiny linear fracture of the postero-superior bony rim of the acetabulum (Fig. I ). Reduction was attempted by a closed manipula...
