Abstract:

Objective To obtain glenoid positioning data from the positions of three palpable points on scapula, in order to analyze force transmission between the humeral head and the glenoid for the therapy of dyskiness in the shoulder joint. Methods Dry scapulae(N=68)were measured and a critical angle θ which relates the plane determined by the three palpable points on the scapula to a plane containing the glenoid center and the first two palpable points was calculated. The position of glenoid by using the critical angle and scapular palpable points was obtained. Results The mean value for θ was (32.36±4.65)°.  Conclusion The obtained θ allows us to determine the position of the glenoid from three palpable points. This information may be used in calculation of forces across the shoulder joint, which in turn allows optimizing the choice of strengthing exercises in patients with dyskiness.
