Abstract
In July 2010 two patients were admitted for bilateral Birmingham Mid Head Resurface (BMHR) two patients for unilateral procedure and were followed for two years. The pre-operative work up, intra-operative complications, early systemic complications, the operating time, positioning of the patient in the bilateral case, positioning of components, the functional score, restoration of limb length and survival rates at two years were discussed in the two groups. All patients had clinical and radiological evaluation at one, three, six and 12 months and annually thereafter in both the groups. No significant difference was found between the two groups with respect to the operating time, 207.42 minutes in the one-stage group and 120 minutes in the single procedure group. The total estimated blood loss was slightly higher in patients undergoing a bilateral procedure than in the one who had single procedure. The postoperative hematocrit at eight hours was significantly lower in the one-stage group, 0.287 as compared with 0.321 but did not change transfusion rate in this unique group of patients. This study demonstrates safety of One-stage bilateral hip mid head resection resurfacing arthroplasty in sickle cell anemia patients with advanced avascular necrosis of femoral head when compliance with sickle cell perioperative care guidelines is exercised.
