Minimally Invasive Technology Combined With Titanium Rod Support In The Treatment Of Early Osteonecrosis Of The Femoral Head

Osteonecrosis of the femoral head (ONFH) is a common and refractory disease that progresses quickly. It can progress to the collapse of the femoral head or to secondary arthritis in a short period of time without timely treatment. This study recruited 39 patients with ONFH from January 2012 to June 2017 and implemented minimally invasive technology combined with titanium rod support to treat their ONFH, and the related indicators were observed. After the operations, the patients' pain was significantly relieved, and their hip joint function was significantly enhanced. After the arthroscopic debridement, the surface of the femoral head cartilage was modified and smooth. Positive and lateral x-ray examinations 12 months after the operations showed that the titanium nails were well supported, and the weight-bearing areas of the femoral heads were not collapsed. After 12 months, two cases progressed from stage II b to stage II c, two cases progressed from stage II c to stage III, with femoral head collapse, so total hip replacements were necessary. This therapy can serve as a reliable and remarkable method for treating ONFH.
