The relationship of the pelvis, acetabulum, spine and femur was studied in the adult in the newborn. It was noted that when the flexed spine and pelvis derotated at or soon after birth, the femoral head dislocated anteriorly in a number of anatomic preparations, and, in the process of "unfolding," the femoral head assumed the classically recognized dislocated position. The "weak" areas in the fibrocartilaginous makeup are also described.

Seven cases of infants whose hips were clinically normal at birth, and in whom hip dislocation was later recognized, are reported. In spite of the widespread practice of routine examination of the hips of newborn babies, infants and young children are still presenting with congenital dislocation of the hip. This is probably owing to there being two aetiological types. Every opportunity to re-examine the hips of children under 2 or even 3 years of age must be taken and a high level of suspicion maintained.

Combining primary open reduction, femoral shortening, capsulorrhaphy, and acetabuloplasty in a single operation allows predictable treatment of congenital dislocation of the hip in older children without the time and expense of preliminary traction. In addition to the bony abnormalities of congenital hip dislocation, the complex pathologic anatomy of the hypertrophied capsule and associated soft tissues must be recognized and corrected. Failure to treat all components of this condition often leads to reduction that is apparently satisfactory in the intraoperative and early postoperative periods but is followed by hip subluxation or redislocation with weightbearing. Correcting all components of the congenital hip dislocation deformity in a single operation provides the best opportunity for early return of normal hip mechanics and function in the older child.
In 68 patients with 101 congenital dysplasias of the hip results of treatment by Pavlik harness were retrospectively analysed. Of the 101 there were 61 dislocations. After six weeks of treatment with the Pavlik harness reduction was achieved in 48 of the 61 dislocated hips (80%). However, because of persisting dysplasia 50% of all cases had to be treated with an abduction device for a few months. There were no complications, in particular osteonecrosis of the femoral head was not observed. Provided well controlled, the Pavlik harness is a good, safe and easy method for treating congenital dislocation of the hip.
Total hip arthroplasty for the treatment of complete congenital dislocation of the hip in the adult has been associated with high rates of complications, including acetabular component loosening, femoral or sciatic nerve palsy, and prosthetic dislocation. Placement of the acetabular component in the true acetabulum has yielded the most durable results, but leads to significant limb lengthening, which is associated with sciatic and femoral nerve palsy. Femoral shortening with a transverse osteotomy tends to be torsionally unstable. Increased femoral anteversion complicates femoral component placement and, if not corrected, can lead to postoperative anterior instability and component dislocation. A new surgical technique that combines total hip arthroplasty with a femoral subtrochanteric shortening derotational double-chevron osteotomy in complete congenital hip dislocation using standard components is described. This procedure has been successfully performed in seven hips.
OBJECTIVE: To discuss conservative methods for treating patients with chronic low back and leg pain associated with the biomechanical and postural alterations related to bilateral congenital hip dislocation. CLINICAL FEATURES: This report describes the cases of 2 adult female subjects with bilateral congenital hip dislocation without acetabula formation who suffered from chronic low back and leg pain managed conservatively by chiropractic methods. The first subject is a 45-year-old woman with a 9-month history of right buttock pain and radiating right leg pain and paresthesia down to the first 2 toes, with a diagnosis of a herniated L4 intervertebral disk. The second subject is a 53-year-old woman who complained of chronic intermittent low back pain and constant unremitting pain on her right leg for the last 3 years. INTERVENTION AND OUTCOME: Chiropractic manipulation utilizing Logan Basic apex and double notch contacts, as well as sacroiliac manipulation on a drop table with a sacrum contact and with a posterior to anterior and superior to inferior (PA-SI) rocking thrust, together with a spinal stabilization exercise program, were used on these 2 patients. Both patients had significant clinical improvement, with reduction on the Visual Analogue Scale (VAS) of 67% and 84%, Oswestry Disability Index improvement of 73% and 81%, and an improvement on the Harris hip score of 71% and 44%, respectively. CONCLUSION: A conservative management approach, including specific chiropractic manipulation and a spinal stabilization exercise program, can help manage the treatment of adult patients with chronic low back and leg pain related to bilateral congenital dislocation of the hips.
