After 55 days, the external axetabular was removed, and through the same lateral approach, a HR was implanted mm cemented femoral head, mm uncemented acetabular cup. 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 acetabuoar External fixator was well tolerated by the patient, with no signs of pin tract infection.

Treatment of high hip dislocation with a cementless stem combined with a shortening osteotomy. Results Average cartilage thickness was significantly greater for the dysplastic hips than the normal hips 1.

Osteoarthritis secondary to developmental dysplasia of the hip DDH is a wcetabular 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.

However, it may not be possible to restore severe limb-length discrepancy nor to correct important deformities on the femoral displasiia, which characterize high-grade DDH. J Bone Joint Surg Br. Due to the resurfaced left hip, limb-length discrepancy increased to 57 mm. Conclusions Dysplastic hips have general fadera cartilage distribution as well as more prominent gradient increase of thickness at the superolateral portion.

Outcome of hip resurfacing arthroplasty in patients with developmental hip dysplasia. Femoral shortening and cementless arthroplasty in Crowe type 4 congenital dislocation of the hip. Total hip replacement in congenital high hip dislocation following iliofemoral monotube distraction.

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

The use of a small-sized iliofemoral distractor with hydroxyapatite coated pins provides a stable and, d 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.

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. Anatomy of the dysplastic hip and consequences for total hip arthroplasty. 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 pin tracts. The patient had a positive bilateral Trendelemburg sign and her hips were highly limited in their range of motion.

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. 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.

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. The acetabular shell was positioned with an inclination of 47 o. 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.

Results of metal-on-metal hybrid hip resurfacing for Crowe type-I and II developmental dysplasia. Considering the patient’s characteristics and the radiological features of both of the acetabular and the femoral sides, severe limb-length aceyabular represented the major limitation to perform a HR.

Particularly in Crowe type III and IV, additional surgical challenges displasix present, such as limb-length discrepancy and adductor muscle contractures.

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. Resurfacing, hip, dysplasia, congenital, bilateral. 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 displawia the implant.

The effect dr superior placement of the acetabular component on the rate of loosening after total hip arthroplasty.

A aectabular limb-length discrepancy was measured on anteroposterior preoperative radiographs Figura 1. 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. Hip resurfacing after iliofemoral distraction for type IV developmental dysplasia of the hip a case report.

The gradient increase of cartilage thickness was significantly greater in the dysplastic hips than the normal hips. Femoral shortening and cementless arthroplasty in high congenital dislocation of the hip.

In Octobercaera year-old female with severe hip pain affected by bilateral DDH type I in the left hip and type IV in the right hip ed to the Crowe classification came to our institute for clinical examination. 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. Considering the positive clinical outcome, the patient wanted to receive the same treatment in the contralateral hip.

Clin Orthop Relat Res. Patient selection and implant positioning are crucial in determining long-term results. In this patient, since the deformities of the left hip were minimal, a HR was implanted.

J Bone Joint Surgy Br. Failure rates of metal-on-metal hip resurfacings: Postoperatively, progressive one mm distraction per day was planned, until the tip of the greater trochanter reached the upper border of the native acetabulum Figura 3.

Cementless total hip replacement with subtrochanteric femoral shortening for severe developmental dysplasia of the hip. Hip resurfacing HR has gained popularity during the past 15 years as a suitable solution for young and active patients affected by hip disease. By using this technique, the hip center of rotation can be restored to a more anatomical position and may lead to improve hip biomechanics, avoiding excessive joint reaction forces.

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.

There was a general trend of gradient increase of cartilage thickness at the superolateral area in normal and dysplastic hips.

BHR prostheses, either implanted in primary osteoarthritis or secondary to DDH, have been reported to have a similar positive survivorship.
