Tensor fascia lata muscle pedicle grafting for avascular necrosis femoral head
Keywords:Avascular necrosis, ONFH, Femur head, Osteonecrosis, Muscle pedicle grafting, Tensor fascia lata
Background: Osteonecrosis of femoral head (AVN) is a disabling condition with ill-defined etiology and pathogenesis. In more than 60% it leads to osteoarthritis of hip joint. Treatment for this condition includes both operative and non-operative methods with variable success rates. Surgical options being aimed at both conservation of femoral head and arthroplasty of hip joint. Aim of our study was to evaluate the efficacy of tensor fascia lata muscle pedicle grafting in the management of osteonecrosis of femoral head.
Methods: 27 cases with a mean age of 38.7 years (range from 24 to 52) who underwent tensor fascia lata muscle pedicle grafting in the management of osteonecrosis of femoral head were prospectively evaluated with a mean follow up period of 7.3 years (range from 3 to 12 years). Watson-Jones approach was used in all patients. Average hospital stay was 12 days. Harris hip score was used for the evaluation of clinical outcome.
Results: In our series of 27 cases, the Harris hip score was excellent (90-100) in 19, good (80-89) in 5, fair (70-79) in 2 and poor (<70) in 1 case at final follow up.
Conclusions: Tensor fascia lata muscle pedicle grafting is an effective, technically easier, pain relieving head-preserving procedure and will improve outcome in properly selected patients with osteonecrosis of femoral head.
