Dynamic CT features of scapholunate instability during the wrist extension to flexion-An in vivo study.

ABSTRACT:

Purpose

This biomechanical study aimed to assess the change in the radioscaphoid and the radiolunate angles during wrist extension to flexion in scapholunate instability compared to the healthy wrist.

Methods

Dynamic CT scans of 19 participants with no history of wrist pathology and 19 patients with scapholunate instability without degenerative changes were selected. Motion sequence studied was wrist extension to flexion. Image segmentation followed by 3D registration techniques were used to calculate the displacement field between scaphoid and lunate models in each time point. The radiocarpal angles and centroid positions were computed in the neutral wrist and throughout wrist motion. Comparisons were made between the normal and the scapholunate instability wrists.
