2. SICKLE CELL DISEASE

4. SICKLE CELL DISEASE
Total hip replacement in such patients who are less than forty years old has been associated with high rates of complications and revisions. Also, the majority of such patients with sickle cell disease have been reported to have a high prevalence of failure of components fixation
The purpose of the present study was to analyze the results after primary total hip arthroplasty with cement in a group of patients who had sickle cell disease

6. The anatomic abnormalities
The anatomic abnormalities may include
abnormal location of neurovascular structures secondary to soft-tissue contractures,
an abnormal location of the hip center,
a limb-length discrepancy,
a small acetabulum and femoral canal
increased anteversion of the proximal part of the femur.

20. 10 hips in patients who had had infection of the hip during childhood
All the hips had cemented total hip replacements. The age of the patients at the time that the infection was contracted was an average of 12 years).
The average age of the patients at the time of the total hip arthroplasty was 32.4 years. The interval between active infection and arthroplasty was 24 years. All the hips had a quiescent period of infection of more than ten years. The average duration of follow-up was 8 years (range, five to fifteen years).
Two hips had recurrence of infection.

35. Conclusion
The management of hip arthroplasty with sickle cell disease requires recognition of anatomical deformities
Assessment begins in the preoperative period with recognition of significant risk factors, including previous surgery systemic medical conditions, as well as selection of suitable components.
