Figure 4From: New method for detection of complex 3D fracture motion - Verification of an optical motion analysis system for biomechanical studies Bland Altman Plot: Interfragmentary motion Δα. The differences of interfragmentary motion (α angle) between the dial indicator and PONOTS 5 M are plotted against the average of the two methods. The solid line indicates the systematic bias between the two methods. The upper and lower limits show the 95% limits of agreement.Back to article page
