Total hip replacement in the paleoacetabulum: biomechanical considerations.

The authors analyze the biomechanics of the dislocated hip in preparation to total hip replacement. Using the Pauwels criteria as a starting point, the authors observe the pathologic modification of this equilibrium when the hip is congenitally dislocated. Finally, applying these criteria to the acetabular component positioned in both the neoacetabulum and the true or paleoacetabulum, the authors show that the latter is biomechanically more advantageous.

Intramedullary pressure changes in proximal femur before and after treatment of congenital dislocation of the hip. Evaluation of the development of the femoral head.

Thirty-four hips were observed radiographically to see the development of the femoral head. The intramedullary pressure was measured in the proximal femur before and after treatment of congenital dislocation of the hips. The intramedullary pressure in the avascular femoral head decreased more obviously than that in the normal head after treatment. A term of "IMP subtraction value" was put forward as an objective index for evaluating the development of the femoral head after treatment of congenital dislocation of the hip.

Evaluating the national screening programme for congenital dislocation of the hip.

In 1969 universal clinical screening for neonatal hip instability was formally adopted in the United Kingdom with the aim of detecting and treating children considered to be at high risk of congenital dislocation of the hip (CDH). However, clinical screening is associated with both false positive and false negative diagnoses and has never been evaluated in a randomised trial. The emergence of hip ultrasound provides renewed impetus to reconsider and formally evaluate screening for CDH. Ultrasound imaging of the newborn hip may be used as a screening test and to assess and manage infants with clinically detected hip instability. Universal primary ultrasound screening has been adopted in some European countries, but enthusiasm for this new technology has been tempered by the subsequent large increases in treatment and follow up. This paper reviews the existing evidence to support the different approaches to screening and describes the research agenda of the MRC working party on congenital dislocation of the hip. A randomised trial of screening is required to evaluate the policy options before ultrasound screening becomes widely adopted within the United Kingdom. The feasibility and acceptability of a trial need to be explored and key issues relating to trial design addressed.

The Altdorf hip clamp.

Forty-one osteotomies internally fixed with the Altdorf hip clamp were reviewed at Nemours Children's Hospital (Jacksonville, FL). They were divided according to pathology: cerebral palsy, 19 patients; congenital dislocated hip, 2 patients; Legg-Calvé-Perthes disease, 8 patients; and other, 2 patients. There were 15 boys and 18 girls, with an average age of 6.9 years (range 2.6-12 years). No intraoperative complications have been reported. Long-term complications are as follows: nonunion, one patient; superficial wound infection, one patient; and loss of position of greater than 15 degrees, two patients.

Avascular necrosis in patients treated with the Pavlik harness for congenital dislocation of the hip.

Two hundred and seventy hips of 220 patients were treated with the Pavlik harness for congenital dislocation. Two hundred and thirty-three hips were dislocated, and thirty-seven hips had acetabular dysplasia. Of the 233 dislocated hips, thirteen (6 per cent) were not reduced. In one hundred and eighty-four hips that were successfully reduced, avascular necrosis did not develop. Avascular necrosis was observed in thirty-six (16 per cent) of the 220 reduced hips. Of these, twenty-seven hips were followed for five to twenty years (average, nine years). The result was excellent or good in eighteen hips (67 per cent), fair in three (11 per cent), and a failure in six (22 per cent). Avascular necrosis was seen in one of the thirty-seven hips that had acetabular dysplasia, and it was found even in the normal hip of a patient who had unilateral dislocation. In this study, the amount of displacement was represented by distances a and b, as defined by Yamamuro and Chene. Distance a is the length from the middle point of the proximal metaphyseal border of the femur to the Y-line, and distance b is the distance from the same point to the lateral margin of the ischium. When distance a was more than four millimeters, the over-all rate of reduction was 97 per cent (209 of 215 hips), ranging from 96 per cent (eighty-two of eighty-five hips) when distance a was eight to ten millimeters to 100 per cent (twenty-nine hips) when distance a was more than ten millimeters.(ABSTRACT TRUNCATED AT 250 WORDS)

Developmental dysplasia of the hip.

Developmental dysplasia of the hip (DDH), formerly known as congenital dislocation of the hip (CDH), is a term used to describe a variety of abnormalities of the hip in development. The treatment options are diverse depending on etiology, degree of dislocation, and age of the child when diagnosis is made. This article provides the reader with a knowledge base to assist with early diagnosis, treatment, and nursing care of the client with dislocations and subluxations of the hip. Presented are the definitions, diagnostic techniques, treatments, and nursing diagnoses and interventions for the client with DDH and for the child's family.

[Hip diseases in children].

In the orthopedic practice, the hip joint is of special importance at all ages. For the general practitioner and the pediatrician are those disorders of the hip of high importance, for which early diagnosis and initiation of treatment is critical for prognosis. The following disorders should be looked for in priority, if symptoms indicate a possible affection of hip: congenital dysplasia and dislocation of the hip, coxitis, slipped capital femoral epiphysis, and tumors. One should always be aware that especially in children disease of the hip need not necessarily present with symptoms directly located within the region of the hip. Especially the child often complains only about knee or vague leg pain, while having a disorder of the hip; therefore, the cause of any pain should always also be looked for proximal to the structure, where the pain may be localized by the patient.
