Effectiveness of extracorporeal shock wave monotherapy for avascular necrosis of femoral head: A systematic review protocol of randomized controlled trial

Background: Previous clinical studies have reported that extracorporeal shock wave (EPSW) monotherapy can effectively treat avascular necrosis of femoral head (ANFH). However, no systematic review has been conducted to assess its effectiveness and safety for patients with ANFH. Therefore, this study will systematically assess the effectiveness and safety of EPSW monotherapy for patients with ANFH.
