Objectives: In osteonecrosis of the femoral head (ONFH), collapse often lead to early surgical treatments due to the intractable hip pain, while there are some cases who make a choice of conservative follow-up without any surgical intervention. In this study, we investigated the clinical course of conservative follow-up more than one year after collapse in ONFH.
Methods: Between 2010 and 2015, 261 patients with ONFH first visited to our hospital. Of these, 30 patients (36 hips) with collapsed ONFH followed conservatively for more than one year were the subjects of this study. There were 20 men and 10 women, with a mean age of 47 years (17-76) at the time of first visit. On the basis of the classification system used, 26 hips were classified as Stage 3A (less than 3 mm femoral head collapse), and 10 hips as Stage 3B (more than or equal to 3mm femoral head collapse). Clinical and radiological factors were retrospectively examined.
Results and Conclusion: During the follow-up, 16 hips (44%) were treated with prosthetic replacement surgery, with a mean follow-up period of 27 months (12-75) after collapse. On the other hand, conservative follow-up was continued in the remaining 20 hips (56%) with a mean follow-up period of 36 months (13-72) after collapse, in which the progression of stage was seen in 13 hips (65%). Further investigations should be done to clarify the quality of life in patients continued with conservative follow-up.
