Hip dysplasia

BACKGROUND: Mistaking the ossific nucleus as the surrogate for the center of the femoral head affects treatment decisions in hip dysplasia. Previous studies of ossific nucleus position within the femoral head have been qualitative, or, have not included both subluxated and dislocated hips. The purpose of this study was, first, to determine the most accurate radiographic landmark to define the center of the immature femoral head in hip dysplasia, and, second, to quantitatively analyze the position of the ossific nucleus relative to the center of the femoral head...

The results of Colonna capsular arthroplasty in twenty-two hips in twenty patients were reviewed. All twenty patients were at least five years old at the time of the operation, which was performed for either complete dislocation or marked subluxation of the hip. None were candidates for reconstructive procedures designed to preserve articular cartilage. The mean age at the time of the Colonna arthroplasty was nine years and three months (range, five years to fifteen years and two months), and the mean duration of follow-up was sixteen years (range, six to thirty-two years)...

BACKGROUND: Codivilla in 1901, Hey Groves in 1926, and Colonna in 1932 described similar capsular arthroplasties--wrapping the capsule around the femoral head and reducing into the true acetabulum--to treat completely dislocated hips in children with dysplastic hips. However, these procedures were associated with relatively high rates of necrosis, joint stiffness, and subsequent revision procedures, and with the introduction of THA, the procedure vanished despite some hips with high functional scores over periods of up to 20 years...

Surgical hip dislocation (SHD) is a versatile approach used to address both intra-articular and extra-articular pathology around the hip joint in both pediatric and adult patients. It allows anterior dislocation of the femoral head for direct visualization of the hip joint while preserving femoral head vascularity and minimizing trauma to the abductor musculature. Previously described indications for SHD include femoroacetabular impingement, deformity resulting from Legg-Calve-Perthes disease, slipped capital femoral epiphysis, periarticular trauma, benign lesions of the hip joint, and osteochondral lesions...

The treatment of the spastic hip in Cerebral Palsy (CP) remains a challenge especially in cases of advance changes. Many options are available and the key for a good outcome is to find the best surgical procedure to an individualized patient. The hip fusion is one of the surgical options. The authors presented a group of spastic CP with painful chronic hip subluxation and dislocation treated with hip fusion with a mean follow-up period of 14.5 years. Surgical technique, post-operative management and outcomes were shown, also with the observations done regarding the evolution of the contralateral hip after the hip fusion...

The following are proceedings from the Hip Breakout Session held at the 2013 annual meeting of the Pediatric Orthopaedic Society of North America in Toronto, Canada. The organizer's goal of the meeting was to gather experts with years of clinical experience to discuss topics based upon both experience and current clinical evidence. The topics that were selected represented the most commonly encountered pathology where there are wide variations of clinical practice. The invited speakers were asked to summarize both their clinical experience and the current scientific evidence and to summarize areas that require further scientific investigation...

BACKGROUND: Radiographic measures of acetabular coverage are essential screening tools used to characterize bony structure contributing to femoroacetabular impingement (FAI). Small changes in pelvic tilt result in altered radiographic measures of acetabular coverage. Positional changes in pelvic tilt are known to occur between the supine and weightbearing positions. It is unclear whether alteration of pelvic tilt between these positions is clinically sufficient to influence measures of acetabular coverage...
