1.Physical therapy Over the past 20 years, more than 400,000 patients with osteonecrosis or delayed fracture healing have experienced physical therapy (electrical stimulation or ultrasound), which has proven that physical therapy does enhance bone healing and is being used as an adjunct in the treatment of fractures, delayed fracture healing and osteonecrosis. Physical methods include: low-intensity pulsed ultrasound (treatment; electrical stimulation therapy; hyperbaric oxygen therapy; extracorporeal shock wave therapy. 2.Local minimally invasive injection therapy Local injection therapy is a method between surgical and non-surgical treatment, and is a minimally invasive treatment, which is best performed under X-ray surveillance for accurate positioning,
It is best to be performed under X-ray surveillance for accurate localization. The use of the author’s group’s original projection navigator can achieve accurate injection and improve the therapeutic effect. The specific methods are: percutaneous injection of autologous bone marrow; percutaneous osteoinductive factor injection; and percutaneous local injection of aureus solution.
