One in five patients require conversion to arthroplasty after non-vascularized bone grafts in patients with osteonecrosis of the femoral head: a systematic review.

ABSTRACT:

Background

Non-vascularized bone grafting (NVBG) has demonstrated to treat osteonecrosis of the femoral head (ONFH). There are a number of articles updating the use of NVBG to treat the ONFH, but the percentage of patients subsequently undergoing a total hip arthroplasty (THA) is controversial.

Methods

Several electronic databases, including PubMed, Embase, Web of Science, and Cochrane databases, were searched to find studies using NVBG to treat ONFH. The pooled rate and 95% confidence interval (CI) were used to assess the conversion rate to THA after NVBG. In addition, we performed subgroup, sensitivity, and publication bias analysis.

Results

A total of 37 studies describing 2599 hips were included. The mean weighted follow-up time was 50.5 months and the mean age at
