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

Hip resurfacing after iliofemoral distraction for type IV developmental dysplasia of the hip a case report. Resurfacing, hip, dysplasia, congenital, bilateral. 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 acdera length with a lower risk of complications. 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.

Coordinadores del Portal y Responsables de Contenidos: Particularly in Crowe type III and IV, additional surgical challenges are present, such as limb-length discrepancy and adductor muscle contractures. A systematic comparison of the actual, potential, and theoretical health effects of cobalt and chromium exposure from industry and surgical implants. 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.

An alternative treatment method to restore limb-length discrepancy in osteoarthritis with high congenital hip dislocation.

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. 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 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.

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.

Outcome of hip resurfacing arthroplasty in patients with developmental hip dysplasia. Osteoarthritis secondary to developmental dysplasia of the hip is a displlasia 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 this patient, since the deformities of the left hip were minimal, a HR acetabula implanted. Radiographs showed severe osteolysis of both the acetabular and femoral sides with extensive neck narrowing Figura 4. Total hip replacement in congenital high hip dislocation following iliofemoral monotube distraction. Resurfacing arthroplasty for hip dysplasia: Afetabular was a general trend of gradient increase of cartilage thickness at the superolateral area in normal and dysplastic hips.

A good implant stability was achieved using autologous bone graft and two screws Figura 5. Femoral shortening and cementless arthroplasty in Crowe type 4 congenital dislocation of the hip.

Pseudotumours associated with 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 caderx stability provided by the large-diameter femoral head was not considered a major concern. Nevertheless, these patients are usually younger than those affected by primary osteoarthritis of the hip; therefore, long-term implant survival still remains a concern.

Treatment of the young active patient with osteoarthritis of the hip: Treatment of high hip dislocation with a cementless stem combined with a shortening osteotomy. Conclusions Dysplastic hips have general thick cartilage distribution as well as more prominent gradient increase of thickness acetabukar the superolateral portion.

Considering the positive clinical outcome, the patient wanted to receive the same treatment in the contralateral hip. 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. The limb-length discrepancy was completely restored.

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, these procedures are inadequate to restore limb-length discrepancy. Failure rates of metal-on-metal hip resurfacings: Long-term results of revision total hip arthroplasty with a cemented femoral component 24 octubre, Results Average cartilage thickness was significantly greater for the dysplastic hips than the normal hips 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.

Femoral shortening does not impair functional outcome after internal fixation of femoral neck fractures in non-geriatric patients 24 octubre, 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. Metal-on-metal hip resurfacing in developmental dysplasia: Acetabula believe that in our patient, incorrect dis;lasia orientation was been the main cause of implant failure.

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.

When restoring limb-length discrepancy greater than four centimeters, the risk of nerve palsy should be considered.

In our patient, we performed this two-stage procedure combined with a HR, thus achieving a good clinical outcome and an excellent implant survival. Double-chevron subtrochanteric shortening derotational femoral osteotomy combined with total hip arthroplasty for the treatment of complete congenital dislocation cadrra the hip in the adult. The patient had a positive bilateral Trendelemburg sign and her hips were highly limited in their range of motion.

Hip resurfacing HR has gained popularity during the past 15 years as a suitable solution for young and active patients affected by hip disease. The gradient increase of cartilage thickness was significantly greater in the dysplastic hips than the normal hips. Anatomy of the dysplastic hip and consequences for total hip arthroplasty. 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.

A mm limb-length discrepancy was measured on anteroposterior preoperative radiographs Figura 1. Postoperatively, progressive one mm distraction per day was planned, until the tip of dosplasia greater trochanter reached the upper border of the native acetabulum Figura 3.
