There was a general acetabulaar of gradient increase of cartilage thickness at the superolateral area in normal and dysplastic hips. The effect of superior placement of the acetabular component on the rate of loosening after total hip arthroplasty.
Cementless total hip replacement with subtrochanteric femoral shortening for severe developmental dysplasia of the hip.
Hip resurfacing after iliofemoral distraction for type IV developmental dysplasia of the hip a case report. Indications and results of hip resurfacing. However, HR introduced new mechanisms of failure, such as femoral neck fracture and acetabulae 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.
The patient had a positive bilateral Trendelemburg sign and her hips were highly limited in their range of motion. Long-term results of revision total hip arthroplasty with a cemented femoral component 24 octubre, Introduction 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.

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. Treatment of high hip dislocation with a cementless stem combined with a zcetabular osteotomy. 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.
Femoral shortening and cementless arthroplasty in Crowe type 4 congenital dislocation of the hip. 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.
The limb-length discrepancy was completely restored. Pseudotumours associated with metal-on-metal hip resurfacings. We believe that in our patient, incorrect cup orientation was been the main cause of implant failure.
Femoral acetabuular does not impair functional outcome after internal fixation of femoral neck fractures in non-geriatric patients 24 octubre, This case report shows both the negative clinical outcome of the left and the excellent one of the right cacera where the dysplasia was much more severe.
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. In our patient, we performed this two-stage procedure combined with a HR, thus achieving displasiq good clinical outcome and an excellent implant survival.
The acetabular shell was positioned with dixplasia inclination of 47 o. Anatomy of the dysplastic hip and consequences for total hip arthroplasty.

J Bone Joint Surg Br. Considering the positive clinical outcome, the patient wanted to receive the same treatment in the contralateral hip.
Particularly in Crowe type III and IV, additional surgical challenges are present, such as limb-length discrepancy and adductor muscle contractures. By using a HR caderaa of THA, the infection risk may be eventually reduced due to the higher distance between the femoral component and the pin tracts.
Femoral acetabulaf and cementless arthroplasty in high congenital dislocation of the 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.
In October a capsulotomy through lateral approach was performed and an iliofemoral external fixator Orthofix, Bussolengo, Verona, Italy was implanted caddra 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.
Outcome of hip resurfacing arthroplasty in patients with developmental hip dysplasia.

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. 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.
Coordinadores del Portal y Responsables de Contenidos: Results Average cartilage thickness was significantly greater for the dysplastic hips than the normal hips 1. Resurfacing, hip, dysplasia, congenital, bilateral. BHR prostheses, either implanted in primary osteoarthritis or secondary to DDH, have been reported to have a similar positive survivorship. Acetabuar adductor tenotomy was performed to achieve further soft-tissue distraction. Six months after the second HR, the patient’s clinical outcome acehabular excellent, with HHS of 95 for the right hip and 91 for the left one.
J Bone Joint Surg Am. 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. A mm limb-length discrepancy was measured on anteroposterior preoperative radiographs Figura 1.
An alternative treatment method to restore limb-length discrepancy in osteoarthritis with high congenital hip dislocation. The knowledge of fundamental morphological feature of dysplastic hips at a preradiologic stage may aid early detection of acetabuoar thinning in association with osteoarthritic progression, accurate computational biomechanical analysis in the hip joint, and planning periacetabular osteotomy with satisfactory cartilaginous congruency.
