3D Analysis of the Proximal Interphalangeal Joint Kinematics during Flexion

Figure 7

Visualization of the intra-articular distance during flexion, depicted in steps of 15°. Palmar is to the left and radial is to the top. The distance is shown in a range from 0 to 3 mm, using a logarithmic scale. First row (left to right): articular distance between neutral position and 30°. Second row (left to right): articular distance between 45° and 75°. Third row (left to right): articular distance between 90° and full flexion.
