Comparison of retrograde anatomy iliac bone flap grafting versus anterograde anatomy iliac bone flap grafting for treatment of osteonecrosis of the femoral head.

ABSTRACT:

Background

Iliac bone flap with deep circumflex iliac artery is a common option in the treatment of Osteonecrosis of the femoral head (ONFH), and dissection of iliac bone flap is the key step for successful operation. This paper aims to introduce a new operative technique for dissecting iliac bone flap with deep circumflex iliac artery based on analysis of its advantages.

Methods

A total of 49 patients treated by retrograde anatomy and 52 patients treated by anterograde anatomy from January 2010 to December 2020 were recruited. The two groups were then compared in terms of the preoperative baseline conditions, intraoperative data, and postoperative Harris hip score (HHS).

Results

Compared with the retrograde anatomy group, the anterograde anatomy group had a significa
