Shi L, Yang X, Wang P, Ma X, Li D, Wu X, Gao F, Sun W. Quantitative Magnetic Resonance Imaging of Femoral Head Articular Cartilage Change in Patients with Hip Osteonecrosis Treated with Extracorporeal Shock Wave Therapy. Int J Clin Pract. 2022 Jun 13;2022:8609868.
Prospective randomised controlled trial. 143 eligible patients with unilateral early-stage ONFH were randomised to: • ESWT group (n=73): received 2 sessions of ESWT (> 0.44mJ/mm² at 4-6 target sites on the fem. head) with oral drug treatment • Control group (n=70): received oral drug treatment only Results • At 3 and 6 months follow-up, pain and function were significantly more improved in the ESWT group than the control group. • At 12 months, T2 mapping on MRI showed a significant delay in cartilage degeneration in the ESWT group compared to the control group.
Key message ESWT added to drug treatment for ONFH provides improvement of pain and function and may delay the degeneration of the femoral head cartilage.
