When restoring limb-length discrepancy greater than four centimeters, the risk of nerve palsy should be considered. The effect of superior placement of the acetabular component on the rate of loosening after total hip arthroplasty. Coordinadores del Portal y Responsables de Contenidos: 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.
J Bone Joint Surgy Br. 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.
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.
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.
This case report shows both the negative clinical outcome of the left and the excellent one of the right hip where the dysplasia was much more severe. 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.
Particularly, the right hip was limited to 60 o in flexion and to 5 o in internal and external rotations. Treatment of the young active patient with osteoarthritis of the hip: Conclusions Dysplastic hips have general thick cartilage distribution as well as more prominent gradient increase of thickness at the superolateral portion.

Indications and results of hip resurfacing. 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.
Nevertheless, these patients are usually younger than those affected by primary osteoarthritis of the hip; therefore, long-term implant survival still remains a concern. 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.
Particularly in Crowe type III and IV, additional surgical challenges are present, such as limb-length discrepancy and adductor muscle contractures. An alternative treatment method to restore limb-length discrepancy in osteoarthritis with high congenital hip dislocation. Metal-on-metal hip resurfacing in developmental dysplasia: Preliminary report and description of a new surgical technique.
Results of metal-on-metal hybrid hip resurfacing for Crowe type-I and II developmental dysplasia. Due to the resurfaced left hip, limb-length discrepancy increased to 57 mm. Clin Orthop Relat Res. 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. Patient selection and implant positioning are crucial in determining long-term results.
There was a general trend of gradient increase of cartilage thickness at the superolateral area in normal and dysplastic hips.
Arch Orthop Trauma Surg. However, these procedures are inadequate to restore limb-length discrepancy. Total hip replacement in congenital high hip dislocation following iliofemoral monotube distraction. Cementless total hip arthroplasty and limb-length equalization in patients with unilateral Crowe type-IV hip dislocation.

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 displasai the Crowe classification came to our institute for clinical examination.
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 acetabularr stage.
Resurfacing arthroplasty for hip dysplasia: Anatomy of the dysplastic hip and consequences cxdera total hip arthroplasty. 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.
A good implant stability was achieved using autologous bone graft and two screws Figura 5. 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.
Considering the positive clinical outcome, the patient wanted to receive the same treatment in the contralateral hip. Introduction Osteoarthritis secondary to developmental dysplasia of the hip DDH is a surgical dd 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.
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. Results of the Birmingham Hip Resurfacing dysplasia component in severe acetabular insufficiency: Femoral shortening and cementless arthroplasty in Crowe type 4 congenital dislocation of the hip.
We believe that in our patient, incorrect cup orientation was been the main cause of implant failure. Results Average cartilage thickness was significantly greater for the dysplastic hips than the normal hips 1. Use of iliofemoral distraction in reducing high congenital dislocation of the hip before total hip arthroplasty.
Six months after the second HR, the patient’s clinical outcome was excellent, with HHS of 95 for the right acetabilar and 91 for the left one.
HR is a dieplasia solution suitable for young and active patients with a long life expectancy where revision surgery is more probable to become necessary. 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.
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. 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. Radiographs showed severe osteolysis of diisplasia the acetabular and femoral sides with extensive neck narrowing Figura 4.
Survivorship, patient reported outcome and satisfaction following resurfacing and total hip arthroplasty. 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. Treatment of high hip dislocation with a cementless stem combined with a shortening osteotomy. The limb-length discrepancy was completely restored.
