Background
Sickle cell disease (SCD) affects around 80,000 people in the USA and 12,000 in the UK. Up to 40% of patients will get osteonecrosis of the femoral head. Cemented acetabular components yield poor results with the rate of osteolysis ranging from 13.5 to 46%. We report on a consecutive cohort of patients with SCD who underwent uncemented THA with ceramic-on-ceramic (CoC) bearings.
Methods
Since 2002 52 primary THAs were carried out in 40 patients. The average age was 36.1 years (17-54). 48 cases had exchange blood transfusion preoperatively and 3 had top-up transfusions.
An S-ROM was used in 47 hips a Solutions stem in 4 hips and an AML in 1. It was necessary to drill the femur during 12 hips. There were 5 intra-operative peri-prosthetic fractures. 2 dislocations were observed. 2 superficial infections were detected.
Results
All components have in-grown. There have been no cases of radiographic osteolysis, migration or loosening of the hip with average 5-year (2-10.1) follow-up.
Conclusions
The combination of a multidisciplinary team approach and uncemented implants, with ceramic-on-ceramic bearings used, has made THA in patients with SCD a safe and reliable procedure in our hospital.
