There was a general trend of gradient increase of cartilage thickness at the superolateral area in normal and dysplastic hips. Failure rates of metal-on-metal hip resurfacings: 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.

When restoring limb-length discrepancy greater than four centimeters, the risk of nerve palsy should be considered. Conclusions Dysplastic hips have general thick cartilage distribution as well as more prominent gradient increase of thickness at the superolateral portion.

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. 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.

Particularly, the right hip was limited to 60 o in flexion and to 5 o in internal and external rotations. Introduction Osteoarthritis secondary to developmental dysplasia of the hip DDH is a surgical challenge because of the modified dksplasia 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 metal-on-metal hybrid hip resurfacing for Crowe type-I and II developmental dysplasia.

Resurfacing, hip, dysplasia, congenital, bilateral. In October a capsulotomy through lateral approach was performed and cader 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 dispplasia the femoral diaphysis with no distraction at the time of surgery.

Results Average cartilage thickness was significantly greater for the dysplastic hips than the normal hips displaaia. A mm limb-length discrepancy was measured on anteroposterior preoperative radiographs Figura 1. Patient selection and implant positioning are crucial in determining long-term results.

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 acetabulr 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. Displasis Bone Joint Surg Am. A good implant stability was achieved using autologous bone graft csdera two screws Figura 5. Clin Orthop Relat Res.

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 Hip resurfacing HR has gained popularity during the past 15 years as a suitable solution for young and active patients affected by hip disease.

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. Hip resurfacing after iliofemoral distraction for type IV developmental dysplasia of the hip a case report.

Considering the positive clinical outcome, the patient wanted to receive the same treatment in the contralateral hip. After 55 days, the external fixator was removed, and through the same lateral approach, a HR was implanted mm cemented femoral head, mm uncemented acetabular cup. This case report shows both the negative clinical outcome of the left hip and the excellent one of the acetzbular one, hip where the dysplasia was much more severe.

Indications and results of hip resurfacing. External fixator was well tolerated by the patient, with no signs of pin tract infection. Survivorship, patient reported outcome and satisfaction following resurfacing and total hip arthroplasty. In this patient, since the deformities of the left hip were minimal, a HR was implanted. In our patient, we performed this two-stage procedure combined with a HR, thus achieving a good clinical outcome and an excellent implant survival.

Pseudotumours associated with metal-on-metal hip resurfacings.

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

Total hip replacement in congenital high hip dislocation following iliofemoral monotube distraction. The effect of superior placement of the acetabular component on the rate of loosening after total hip arthroplasty.

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

An alternative treatment method to restore limb-length discrepancy in osteoarthritis with high congenital hip dislocation. Femoral shortening and cementless arthroplasty in Crowe type 4 congenital dislocation of the hip.

Femoral shortening and cementless arthroplasty in high congenital dislocation of the hip. 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. Outcome of hip resurfacing arthroplasty in cacera with developmental hip dysplasia.
