Three-dimensional computed tomography mapping and clinical predictive factors for morphologic characterization of displaced femoral neck fractures.

ABSTRACT:

Background

This study aimed to define the distribution and frequency of fracture lines and bone defects in displaced femoral neck fractures (DFNFs) using a three-dimensional (3D) mapping technique, and to investigate the factors associated with the area of bone defects in patients with DFNFs.

Methods

The data of 256 adult patients with DFNFs were retrospectively reviewed. Multiplanar reconstructions of the DFNFs were made using computed tomography (CT) images, and the DFNF fragments were virtually reduced to match a 3D model of the femoral neck. Subsequently, 3D mapping was performed by graphically superimposing all of the fracture lines and bone defects onto a femoral neck template. The 3D mappings were independently examined by two orthopedic surgeons, and the interobserve
