Estimation of neck shaft angle of dry radii for prosthetic replacement
Journal Title: Indian Journal of Clinical Anatomy and Physiology - Year 2017, Vol 4, Issue 3
Abstract
Introduction: Radial head prosthesis is a valuable option in patients with radial head and neck fractures who require radial head replacement. Neck shaft angle (NSA) is an important morphometric measurement for stem design of radial head prosthesis in head and neck fractures to enable adequate movements of forearm following post operative management. Aims and Objectives: a) To estimate neck shaft angle of proximal end of right and left radii. b) To compare neck shaft angle of proximal end of right and left radii. Materials and Method: Digital photographs of posterior surface of all 142(71 left & 71 right) radii were taken. Lines were drawn using Microsoft power point software. Image was saved as a picture and opened with Image J analyser which measured neck shaft angle. Statistical analysis was done using SPSS. Results: The mean neck shaft angle was 168.01±3.65°. Right side was 165.67±4.44° and left side was 168.01±3.65°. There was significant difference between left and right side values of neck shaft angle. Conclusion: Mean values of neck shaft angle were comparable with previous studies. Side difference should be considered while implanting prosthesis on affected side.
