We believe that in our patient, incorrect cup orientation was been the main cause of implant failure. In October a capsulotomy 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 acetabulsr of surgery.

The limb-length discrepancy was completely restored.

Long-term results of revision total hip arthroplasty with caxera cemented femoral component 24 octubre, Osteoarthritis secondary to developmental dysplasia of the hip 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 femoral head. Use of iliofemoral distraction in reducing high congenital dislocation of the hip before total hip arthroplasty.

Femoral shortening and cementless arthroplasty in Crowe type dr congenital dislocation of the hip. When restoring limb-length discrepancy greater than four centimeters, the risk of nerve palsy should be considered.

However, these procedures are inadequate to restore limb-length discrepancy.

HR is a bone-preserving displasiq suitable for young and active patients with a long life expectancy where revision surgery is more probable to become necessary. 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.

Moreover, particularly in Crowe type III and IV, 2 additional surgical challenges are present, such as limb-length discrepancy and adductor muscle contractures.

Conclusions Dysplastic hips have general thick cartilage distribution as well as more prominent gradient increase of thickness at dispplasia superolateral portion. By using this technique, the hip center of rotation can be restored acetabklar a more anatomical position and acetxbular lead to improve hip biomechanics, avoiding excessive joint reaction forces.

Results Average cartilage thickness was significantly greater for the dysplastic hips than the normal hips 1. Indications and results displaska hip resurfacing. Failure rates of metal-on-metal hip resurfacings: Metal-on-metal hip resurfacing in developmental dysplasia: Percutaneous adductor tenotomy was performed to achieve further soft-tissue distraction.

The effect of superior placement of the acetabular component on the rate of loosening after total hip arthroplasty. Preliminary report and description of a new surgical technique. In our patient, affected by grade IV DDH after restoring limb-length discrepancy using external fixator, HR allowed to obtain excellent results in terms of functional improvement and implant survival.

By using a HR instead of THA, the infection risk may be eventually reduced due to the higher distance between the femoral component and the caeera tracts. Treatment of high hip dislocation with a cementless stem combined with a shortening osteotomy. Particularly, the right hip was limited to 60 o in flexion and to 5 o in internal and external rotations.

The acetabular shell was positioned with an inclination of 47 o. Particularly in Crowe type III and IV, additional surgical challenges are present, such as limb-length discrepancy and adductor muscle contractures.

The patient had a positive bilateral Trendelemburg sign and her hips didplasia highly limited in their range of motion. 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 aetabular pseudo-tumor, osteolysis, ALVAL or may theoretically produce systemic effects renal failure, carcinogenity, cobaltism.

In this patient, since the deformities of the left hip were minimal, a HR was implanted. In Octobera year-old female with severe hip pain affected by bilateral DDH type I in the left hip and type IV in the right hip according to the Crowe classification came to our institute for clinical examination. Introduction 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.

Results of the Birmingham Hip Resurfacing dysplasia component in severe acetabular insufficiency: 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.

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. Excluding large-diameter metal-on-metal THA, which recently experienced a high revision rate, a similar good survival for stemmed prostheses and the BHR resurfacing system has been reported in young patients affected by low grade DDH.

In our patient, we displaaia this two-stage procedure combined with a HR, thus achieving a good clinical outcome and an excellent implant survival.

Femoral shortening does not impair functional outcome after internal displazia of femoral neck fractures casera non-geriatric patients 24 octubre, This is a bilateral hip dysplasia case where bilateral hip replacement was indicated, on the left side with a resurfacing one and on the other side a two stage procedure using a iliofemoral external fixator to restore equal leg length with a lower risk of complications.

Case report In Octobera year-old female with severe hip pain affected by bilateral DDH type I in the left hip and type IV in the right hip according to the Crowe classification came to our institute for clinical examination.

At the time of the first operation, the edge wear phenomenon was not completely known; therefore, the steep cup inclination 67 o due to the high stability provided by the large-diameter femoral head was not considered a major concern. The dieplasia shell was positioned with an inclination of 67 o Figura 2. 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 discharging the patients, permitted non-weight bearing walking on the affected side, between the first and the second stage.

Outcome of hip resurfacing arthroplasty in patients with developmental hip dysplasia. Due to the resurfaced left hip, limb-length discrepancy increased to 57 mm. The two-stage procedure using an iliofemoral external fixator to distract soft tissue before the THA is indicated in Crowe type III and IV to restore equal leg length with a lower risk of complications. Hip resurfacing HR has gained popularity during the past 15 years as a suitable solution for young and active patients affected by hip disease.

A mm limb-length discrepancy was measured on anteroposterior preoperative radiographs Figura 1. Resurfacing, hip, dysplasia, congenital, bilateral. Double-chevron subtrochanteric shortening derotational femoral osteotomy combined with total hip arthroplasty for the treatment of complete congenital dislocation of the hip in the adult. Now, it cadeta well known that metal-on-metal coupling does not tolerate cup malpositioning, which must have an inclination dizplasia 40 o and 50 o and an anteversion from 10 to 20 o.
