Comparison of early results of vascularized and non-vascularized fibular grafting in the treatment of osteonecrosis of the femoral head
Abstract
Methods: Between January 1999 and June 2008, 11 osteonecrotic hips of 8 patients who underwent vascularized fibular grafting and 15 osteonecrotic hips of 13 patients who underwent nonvascularized fibular grafting were compared according to etiology, stage, age, sex, preoperative and postoperative first year Harris hip and VAS scores.
Results: Steroid use was the most common etiologic factor, found in 26 hips of 21 patients in the entire patient population. There was no significant difference between the two groups according to their age, sex and preoperative Harris hip scores (p>0.05). According to the Ficat staging system for radiological evaluation, 4 hips were Grade 2A, 4 hips were Grade 2B, and 3 hips were Grade 3 in the vascularized group and 8 hips were Grade 2A, 3 hips Grade 2B, 3 hips Grade 3 and one hip was identified as Grade 4 in the non-vascularized group. When the Harris hip and VAS scores of both groups were evaluated, the group treated by vascularized fibular grafting had significantly higher scores than the ones treated by non-vascularized fibular grafting in the other group (p<0.05). Furthermore, when the Harris hip and VAS scores of preoperative and postoperative first year of vascularized fibular grafting patients were compared, there were significantly higher scores after the surgery.
Conclusion: Although there was no significant radiological difference in the early results of both surgical techniques, the clinical results of vascularized fibular grafting treatment were significantly better than the results of non-vascularized fibular grafting treatment in the osteonecrosis of the femoral head. Vascularized fibular grafting improves the clinical status at an early period and prevents subchondral collapse.
