Dysplasia Of The Hip

The anatomy of the acetabulum and femur is usually significantly altered in people with developmental dysplasia of the hip and this leads to secondary osteoarthritis of the hip joint. Ideal positioning of implants and reduction of the joint is technically demanding during arthroplasty. Lengthening may result in nerve palsies and therefore procedures may have to be undertaken to shorten the femur. Other complications include dislocation and non-union at the shortening osteotomy site. Thorough preoperative planning and templating is required before surgery to assess the need for shortening. Shortening osteotomies can be performed at the proximal femur, diaphysis or distal femoral levels, with subtrochanteric being the most common level. The procedure should be customised for each patient after extensive planning and detailed counselling.

Abstract Purpose The aims of the present study is to evaluate the roles of collagen I and III in the hip capsule in the postoperative clinical function of patients with developmental dysplasia of the hip (DDH). Methods Hip capsules from 155 hips of 120 patients were collected during surgery. The patients were divided into three groups according to age: I: 2–3.5 years; II: 3.5–5 years; and III: 5–6 years. Patient clinical function and radiographic outcomes were evaluated with the McKay scores and Severin classification. The expression of collagen I and III was detected through immunohistochemistry and quantitative reverse transcription polymerase chain reaction (RT-PCR) and analysed according to age, sex, degree of dislocation and McKay classification. All patients received open reduction and pelvic osteotomy and/or femoral shortening osteotomy and achieved good results on the basis of postoperative X-ray imaging. Results The average follow-up time was 3.4 years (range 2–4.3 years). There were no changes in the expression of collagen III in the different groups. The expression of collagen I according to age and sex was not significantly different. Lower expression of collagen I was observed in DDH patients with a higher degree of dislocation according to the Tonnis grade. The highest expression of collagen I was detected in the group with poor clinical function according to the McKay classification. Conclusion Collagen I is correlated with the degree of dislocation and is a risk factor for poor clinical function in DDH patients. Collagen I is correlated with the degree of hip dislocation and poor clinical function in DDH patients.
