Abstract
Abstract
Objectives: Research of the clinical results of patients diagnosed with avascular necrosis of the femoral head and treated with free vascularized fibular flap.
Methods: Thirteen hip joints of 10 patients who were treated with vascularized fibula for the diagnosis of avascular necrosis of the femoral head were inspected. Stage of disease was grouped according to the Steinberg staging system, and stage II-III patients underwent free vascularized fibular flap surgery. Preoperative and postoperative Harris hip score, VAS scores, and Steinberg stages of the patients were compared.
Results: The patients were followed for an average of 28 months (range 7 to 42). Pre-operative and post-operative Harris hip score of the patients were found to be 55.2 and 95.3 on average, respectively (p <0.05). The pre-operative and post-operative mean VAS score was found to be 7.07 and 0.61, respectively (p <0.05) and a significant decrease was observed. While the pre-operative stage of the patients was 2.2 on average, the stage detected in the last control was monitored as an average of 1.7 (p <0.05) and a significant decrease was recorded.
Conclusion: In patients with early stage avascular necrosis of the femoral head, if surgical treatment is performed with free vascularized fibular flap, the development of degenerative arthritis is prevented and the need for total hip arthroplasty is reduced. In addition, the hip joint functions are preserved and allows to patients for painless motion.
