ARTROPLASTIA TOTAL DA ANCA PDF

Hip desarthrodesis, which is the conversion of an arthrodesis or of a surgical bone fusion into a hip replacement arthroplasty, is a difficult and challenging operation because of the need of a joint reconstruction in cases with bone fusion and an often long-term immobilization between the femur and the acetabulum, with important anatomic changes, retractions of adjacent soft tissues, and an associated limb shortening. Hip arthrodesis is an operation performed less and less; consequently, its desarthrodesis is even rarer. The present report details three rare cases of patients with long-term hip arthrodesis who were submitted to hip replacement conversion arthroplasty; it describes the applied surgical techniques and their clinical and functional outcomes. Due to the increase of the functional requirements of the patients and to the survival time of total hip arthroplasty, as well as to the development of conservative surgeries for painful hip, hip arthrodesis became a resourceful intervention and an option for last-line revision. Moreover, the gait of the patient is limited, and many individuals are not able to sit down.

ISSN Objective: describe a surgical technique and to evaluate the results of cementless arthroplasty with a simultaneous subtrochanteric shortening osteotomy in a patient with bilateral Crowe type - IV developmental dysplasia of the hip. Methods: a 62 year old woman with a known history of untreated bilateral Developmental Displacement of the Hip. History of joint replacement with transverse subtrochanteric osteotomy at left hip. Subsequently right hip arthroplasty with femoral shortening osteotomy by Mayo Clinic technique.

Results: the follow up period was 25 months for transverse sub trochanteric osteotomy procedure and 17 months for the Mayo Clinic technique. Both surgical acts occurred with proper technical execution, and there were no complications.

Were not observed during follow-up criteria of heterotopic ossification or components loosening. The Harris Hip Score initial stood in values of 40 having evolved after the two surgical procedures for values greater than The initial pain described as severe and persistent improved to mild or occasional. Conclusions: joint replacement for high dislocations Crowe type IV implies with regularly a shortening femoral osteotomy to prevent neurological damage by stretching the sciatic nerve.

The procedure of sub trochanteric osteotomy allows prevent nonunion after advancement osteotomy of the greater trochanter as well as the weakening of the abductor muscles. The technique of Mayo Clinic adds a superior contact bone - bone at the osteotomy site and setting intraoperative limb length.
