Failure rates of metal-on-metal hip resurfacings: 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 displasua local effects pseudo-tumor, osteolysis, ALVAL or may theoretically produce systemic effects renal failure, carcinogenity, cobaltism.

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.

Considering the positive clinical outcome, the patient wanted to receive displssia same treatment in the contralateral hip.

Double-chevron subtrochanteric shortening derotational femoral osteotomy combined with total hip arthroplasty for the sisplasia of complete congenital dislocation of the hip disolasia the adult. Resurfacing, hip, dysplasia, congenital, bilateral.

Particularly, the right acetabulqr was limited cadsra 60 o in flexion and to 5 o in internal and external rotations. 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.

Patient selection and implant positioning are crucial in determining long-term results. Results Average cartilage thickness was significantly greater for the dysplastic hips than the normal hips 1.

Metal-on-metal hip resurfacing in developmental dysplasia: 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.

Femoral shortening does not impair functional outcome after internal fixation of femoral neck fractures in non-geriatric patients 24 octubre, 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 displasa young patients affected by low grade DDH. A good implant stability was achieved using autologous bone graft and two screws Figura 5.

Results of the Birmingham Hip Resurfacing dysplasia component in severe acetabular insufficiency: Now, it is well known that metal-on-metal coupling does not tolerate cup malpositioning, which must have an inclination between 40 o and 50 o and an anteversion from 10 to 20 o.

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.

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 Pseudotumours associated with metal-on-metal hip resurfacings.

In this patient, since the deformities of the left hip were minimal, a HR was implanted.

By using this technique, the hip center of aetabular can cadeera restored to a more anatomical position and may lead to improve hip biomechanics, avoiding excessive joint reaction forces.

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 time of surgery.

Particularly in Crowe type III and IV, additional surgical challenges are present, such as limb-length discrepancy and adductor muscle contractures. Case report In Octobera year-old female with severe hip pain affected by bilateral DDH type Dsplasia in the left hip and type IV in the right hip according to the Crowe classification came to our institute for clinical examination.

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. Treatment of high hip dislocation with a cementless stem combined with a shortening osteotomy. Conclusion In our patient, affected by grade IV DDH after restoring aectabular 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 pin tracts.

Coordinadores del Portal y Responsables de Contenidos: Due to the resurfaced left hip, limb-length discrepancy increased to 57 mm.

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.

HR is a bone-preserving solution suitable for young and active patients with a long life expectancy where revision surgery is more probable to become necessary. 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. 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, cafera deformities of the femur and the altered morphology of the femoral head.

Considering the patient’s characteristics and the radiological features displaska both of the acetabular and the femoral sides, severe limb-length discrepancy represented the major limitation to perform a HR.

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

Design Forty-five dysplastic hips without joint space narrowing on radiographs and 13 normal hips underwent MR imaging with fat-suppressed 3D fast spoiled gradient echo SPGR sequence. 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. 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.
