Three-Dimensional Measurements of Glenohumeral Joint Surfaces in Sheep, Cat and Rabbit by Photogrammetry

摘要

The aim of this study, was the 3-dimensional analysis of the glenohumeral joints of the sheep, cat and rabbit. Twelve glenohumeral joints of animals were examined as materials. The surface areas of the glenoid cavity and the caput of the humeral head, the maximum cranio-caudal and medio-lateral depths of the glenoid cavity, the maximum cranio-caudal and medio-lateral heights of the humeral head, the cranio-caudal and medio-lateral curvature distances of the glenoid cavity and the cranio-caudal and medio-lateral curvature distances of the humeral head were measured by photogrammetric technique in the animals. Ratios amongst surface area of glenoid cavity and caput of humeral head, maximum cranio-caudal depth of glenoid cavity and height of humeral head, maximum medio-lateral depth of glenoid cavity and height of humeral head, cranio-caudal curvature distance of glenoid cavity and humeral head and medio-lateral curvature distance of glenoid cavity and humeral head were determined. The sheep had the largest values for the glenohumeral joint, except for some ratios. Cats had the smallest ratios for all measured values. As a result, this photogrammetric technique may be useful for veterinary anatomy and surgery.
