Abstract

This study investigated the effects of shockwave on systemic concentrations of nitric oxide (NO) level, angiogenic and osteogenic and anti-inflammatory factors in hips with osteonecrosis of the femoral head (ONFH). Thirty-five patients (47 hips) with ONFH were enrolled in this study. Each hip was treated with 6,000 impulses of shockwave at 28 kV in a single session. Ten milliliters of peripheral blood was obtained for the measurements of serum NO level, angiogenic factors (VEGF, vWF, FGF basic and TGF-β1); osteogenic factors (BMP-2, osteocalcin, alkaline phosphatase, DKK-1 and IGF); and anti-inflammation markers (sICAM and sVCAM) before treatment and at 1, 3, 6 and 12 months after treatment. The hips were evaluated with clinical assessment, serial radiograph and MRI. At 12 months, the overall results showed 83% improved and 17% un-improved. Total hip was performed in 4 cases (8.5%). Serum NO3 level showed significant elevation at 1 month after treatment, but the changes at 3, 6 and 12 months were not significant. For angiogenesis, significant elevations of VEGF, vWF and FGF basic and a decrease in TGF-β1 were observed at 1 month, but the changes at 3, 6 and 12 months were non-significant. For osteogenesis, BMP-2, osteocalcin, alkaline phosphatase and IGF were significantly elevated, while DKK-1 was decreased at 1 month, but the changes at 3, 6 and 12 months were not significant. For anti-inflammation markers, significant decreases in sICAM and sVCAM were noted at 1 month after treatment, but the changes at 3, 6 and 12 months were non-significant. Local ESWT application results in significant elevations of serum NO level, angiogenic and osteogenic and anti-inflammatory factors in ONFH.
