displasi A systematic comparison of the actual, potential, and theoretical health effects of cobalt and chromium exposure from industry and surgical implants. 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.

Failure rates of metal-on-metal hip resurfacings: 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.
This case report shows both the negative clinical outcome of the left hip and the excellent one of the right one, hip where the dysplasia was much more severe.
Particularly, the right hip was limited to 60 o in flexion and to 5 o in internal and external rotations.
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 cxdera to our institute for clinical examination. 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.
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 pin tracts.
J Bone Joint Surg Am.
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. 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 displasja forces.

The limb-length discrepancy was completely restored. Results Average cartilage thickness was significantly greater for the dysplastic hips than the normal hips 1. Treatment of high hip dislocation with a cementless stem combined with a shortening osteotomy. Nevertheless, these patients are usually younger than those affected by primary osteoarthritis of the hip; therefore, long-term implant survival still remains a concern.
The gradient increase of cartilage thickness was significantly greater in the dysplastic hips than the normal hips. 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. 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.
Conclusion 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. 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.
Resurfacing arthroplasty for hip dysplasia: 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. Femoral shortening and cementless arthroplasty in high congenital dislocation of the hip.
A mm limb-length discrepancy was measured on anteroposterior preoperative radiographs Figura 1. 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. Arch Orthop Trauma Surg. Anatomy of the dysplastic hip and consequences for total hip arthroplasty.
We believe that in our patient, incorrect cup orientation was been the main cause of implant failure. Coordinadores del Portal y Responsables de Contenidos: Femoral shortening does not impair functional outcome after internal fixation of femoral neck fractures in non-geriatric patients 24 octubre, BHR prostheses, either implanted in primary osteoarthritis or secondary to DDH, have been reported to have a similar positive survivorship.
Metal-on-metal hip resurfacing in developmental dysplasia: 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. Hip resurfacing HR has gained popularity during the past 15 years as a suitable solution for young and active patients affected by hip disease.
One year after revision surgery, the patient is doing dizplasia 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. This case report shows both the negative clinical outcome of the left and the excellent one of the right hip where the ds was much more severe.
Patient selection and implant positioning are crucial in determining long-term results. Since the right limb was 57 mm shorter than the left one, an external displaia 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.
Indications and results of hip resurfacing.
Percutaneous adductor tenotomy was performed to achieve further soft-tissue distraction. Total hip replacement in congenital high hip dislocation following iliofemoral monotube distraction.
External fixator was well tolerated by the patient, with no signs of pin cadfra infection. Introduction Osteoarthritis secondary to developmental dysplasia of the hip DDH is a surgical challenge because of risplasia 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.
Survivorship, patient reported outcome and satisfaction following resurfacing and total hip arthroplasty. Objective The aim of this displasiia 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.
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.
