Introduction

Subchondral insufficiency fractures of the femoral head (SIFFH) occur with normal or physiological stress in patients with poor bone quality. We evaluated the clinical characteristics of SIFFH.

Methods

Nine cases of SIFFH were treated and followed up for an average of 9 months. Femoral head collapse (FHC) on radiographs was classified as minimal (< 2 mm), moderate (2-4 mm), and severe (> 4 mm). The severity of osteopenia was scored by Singh index (SI). Other characteristics of SIFFH were ascertained by assessing the clinical course as well as Body Mass Index (BMI) and magnetic resonance imaging (MRI).
