Clin Orthop Relat Res. Six months after the second HR, the patient’s clinical outcome was excellent, with HHS of 95 for the right hip and 91 for the left one. Preliminary report and description of a new surgical technique. The limb-length discrepancy was completely restored.

Particularly in Crowe type III and IV, additional surgical challenges are present, such as limb-length discrepancy and adductor muscle contractures. One year after revision surgery, the patient is doing well; hip pain has disappeared on the left side HHS 95while the right one has still an excellent clinical outcome HHS 98with radiographs showing a complete osteointegration of the implant.

In order to minimize this complication, different surgical techniques, such as femoral shortening with subtrochanteric osteotomy or cup positioning with a high center of rotation, have been proposed for one-stage treatment.

Osteoarthritis secondary to developmental dysplasia of the hip DDH is a surgical challenge because of the modified anatomy of the acetabulum, which is deficient in its shape, with poor bone quality, torsional deformities of the femur and the altered morphology of the femoral head. Objective The aim of this study was to evaluate three-dimensional 3D distribution of acetabular articular cartilage thickness in patients with hip dysplasia using in vivo magnetic resonance MR imaging, and to compare cartilage thickness distribution between normal and dysplastic hips.

Patient selection and implant positioning are crucial in determining long-term results. A mm limb-length discrepancy was measured on anteroposterior preoperative radiographs Figura 1. In this patient, since the deformities of the left hip were minimal, a HR was implanted.


By using actabular HR instead of THA, the infection risk acetanular be eventually reduced due to the higher distance between the femoral component and the pin tracts. Percutaneous adductor tenotomy was performed to achieve further soft-tissue distraction. Results of metal-on-metal hybrid hip resurfacing for Crowe type-I and II developmental dysplasia. Indications and results of hip resurfacing.

Results Average cartilage thickness was significantly greater for the dysplastic hips than the normal hips 1. Acetabular cartilage thickness was measured with a fully automated segmentation technique, and cartilage thickness distribution was compared between the dysplastic and normal hips on the celestial spherical coordinate system.

Use of iliofemoral distraction in reducing high congenital dislocation of the hip before total hip arthroplasty. The acetabular shell was positioned with an inclination of 67 o Figura 2.

Annually scheduled follow-up for clinical and radiographical examinations showed excellent outcome until Aprilwhen the patient started complaining of groin pain on the left side HHS was Femoral shortening and cementless arthroplasty in high congenital dislocation of the hip. Resurfacing arthroplasty for hip dysplasia: A systematic comparison of the actual, potential, and theoretical health effects of cobalt and chromium exposure from industry and surgical implants.

We believe that in our patient, incorrect cup orientation was been the main cause of implant failure.

However, these procedures are inadequate to restore limb-length discrepancy. The use of a small-sized iliofemoral distractor with hydroxyapatite coated pins provides a stable and, at the same time, non-cumbersome system which allows displsaia the patients, permitted non-weight bearing walking on the affected side, between the first and the second stage.

Long-term results of revision total hip arthroplasty with a cemented femoral component 24 octubre, Anatomy of the dysplastic hip and consequences for total hip arthroplasty. However, HR introduced new mechanisms of failure, such as femoral neck fracture and increased serum concentrations of metal ions that may lead to either local effects pseudo-tumor, osteolysis, ALVAL or may theoretically produce systemic effects renal failure, carcinogenity, cobaltism.


Conclusions Dysplastic hips have general thick cartilage distribution as well as more disppasia gradient increase of thickness at the superolateral portion. However, it may not be possible to restore severe limb-length discrepancy nor to correct important deformities on the femoral side, which characterize high-grade DDH. Failure rates of metal-on-metal hip resurfacings: The patient had a positive bilateral Trendelemburg sign and her hips were highly limited in their range of motion.

BHR prostheses, either implanted in primary osteoarthritis or secondary to DDH, have been reported to have a cadega positive survivorship. Since the right limb was 57 mm shorter than the left one, an external iliofemoral fixator was used for soft-tissue distraction to reduce the risk of nerve palsy and to be able to implant the acetabular cup into the true acetabulum. There was a general trend of gradient increase of cartilage thickness at the superolateral area in normal and dysplastic hips.

In October a cdera through lateral approach was performed and an iliofemoral external fixator Orthofix, Bussolengo, Verona, Italy was implanted using three hydroxyapatite coated pins 16 on the lateral aspect of the iliac wing and two pins inserted into the femoral diaphysis with no distraction at the time of surgery.

Cementless total hip arthroplasty and limb-length equalization in patients with unilateral Crowe type-IV hip dislocation.
