Pediatric hip dislocation: femoral epiphysis (ossified nucleus) not appear can be reset? Patient Question: Disease:Right Hip DislocationDescription:The baby is 17 months old, and the pelvis is positive for the film shows right hip dislocation, what to do. The doctor suggested six months later, to wait for the epiphysis to be born before surgery. Please give some advice. Quanzhou Children’s Hospital Pediatric Orthopaedics Liu Shaofeng replied: Hello, from the X-ray radiographs show that the child’s right hip is dislocated. Osteoid nucleus pulposus dysplasia of the femoral head has not yet appeared. I suggest a trial reset under anesthesia, and intraoperative hip arthrography to determine the alignment of the head and socket. The width of the medial contrast pool, the shape of the labrum, and the cartilaginous coverage of the femoral head were used to determine whether the repositioning was acceptable. Late appearance of the nucleus pulposus of the femoral head is one of the manifestations of hip dysplasia, but current research suggests that the absence of the nucleus pulposus is not a contraindication to closed resurfacing. The younger the child, the greater the potential for acetabular contouring, and if the imaging suggests that a good quality resurfacing can be achieved, the earlier the resurfacing, the better the utilization of the child’s valuable acetabular developmental potential. We have a lot of experience in this field and we recommend a visit to our clinic.
