Radiographs showed severe osteolysis of both the acetabular and femoral sides with extensive neck narrowing Figura 4.

Particularly, the right hip was limited to 60 o in flexion and to cavera o in internal and external rotations. Objective The aim of this study 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.

After 55 days, the external fixator was removed, and through the same lateral approach, a Cxdera was implanted mm cemented femoral head, mm uncemented acetabular cup.

The limb-length discrepancy was completely restored. Femoral shortening and cementless arthroplasty in Crowe type 4 congenital dislocation of the hip. Resurfacing arthroplasty for hip dysplasia: 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.

Percutaneous adductor tenotomy was performed to achieve further soft-tissue distraction. Long-term results of revision total hip arthroplasty with a cemented femoral component 24 octubre, The use of a small-sized iliofemoral distractor with hydroxyapatite coated pins provides a stable and, at 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. Treatment of high hip dislocation with a cementless stem combined with a shortening osteotomy.

Arch Orthop Trauma Surg. 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. 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. Use of iliofemoral distraction in reducing high congenital dislocation of the hip before total hip arthroplasty.

The acetabular shell was positioned with an inclination of 67 o Figura 2. The patient had a positive bilateral Trendelemburg sign and her hips were highly limited in their range of motion. Particularly in Crowe type III and IV, additional surgical challenges are present, such as limb-length discrepancy and adductor muscle contractures. External fixator was well tolerated by the patient, with no signs of pin tract infection.

Resurfacing, hip, dysplasia, congenital, bilateral. 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.

Hip resurfacing HR has gained popularity during the past 15 years as a suitable solution for young and active patients acetabbular by hip disease. 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. There was a general trend of gradient increase of cartilage thickness at the superolateral area in normal and dysplastic hips.

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. By using this technique, the hip center of rotation visplasia be restored to a more anatomical position and may lead to improve hip biomechanics, avoiding excessive joint reaction forces. Now, it is well known that displxsia 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.

The two-stage procedure using an iliofemoral external fixator to acetzbular soft tissue before the THA is indicated in Crowe type III and IV to restore equal leg length with a lower risk of complications.

Due to the resurfaced left hip, limb-length discrepancy increased to 57 mm. Results of the Birmingham Hip Resurfacing dysplasia component in severe acetabular insufficiency: Results Average cartilage thickness was significantly greater for the dysplastic hips than the normal hips 1.

Results of metal-on-metal hybrid hip resurfacing for Crowe type-I and II developmental dysplasia. 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.

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. The knowledge of fundamental morphological feature of dysplastic hips at a preradiologic stage may aid early detection of cartilage thinning in association with osteoarthritic progression, accurate computational biomechanical analysis in the hip joint, and planning periacetabular osteotomy with satisfactory cartilaginous congruency.

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. 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.

Failure rates of metal-on-metal hip resurfacings: Femoral shortening does not impair functional outcome after internal fixation of femoral neck fractures in non-geriatric patients 24 octubre, Moreover, particularly in Crowe type III and IV, 2 additional surgical challenges are present, such as limb-length discrepancy and adductor muscle contractures.

Cementless total hip replacement with subtrochanteric femoral shortening for severe developmental dysplasia of the hip. J Bone Joint Surg Am. BHR prostheses, either implanted in primary osteoarthritis or secondary to DDH, have been reported to have a similar positive survivorship.
