Design outcomes

Primary

Measure	Time frame
The aim is to gain basic dynamic information (motion patterns) of the carpal bones of the proximal and distal row in patients with scaphoid nonunion. We specifically test the hypothesis that the fracture location with respect to the scaphoid apex is related to the kinematic pattern. Because anatomic variance of the insertion of the dorsal intercarpal ligament is known, this study compares the fractured wrist with the contralateral unharmed side in the same individual. We expect to detect abnormal motion patterns, which we will quantify in measurable values (3 translations and 3 rotations of carpal bones during motion of the hand). Delineation of specific motion patterns and discriminative values of dynamic information of the carpal bones will enable us to set up new definitions for diagnosing scaphoid nonunion wrist pathologies.	—

We specifically test the hypothesis that the fracture location with respect to the scaphoid apex is related to the kinematic pattern. Because anatomic variance of the insertion of the dorsal intercarpal ligament is known, this study compares the fractured wrist with the contralateral *unharmed* side in the same individual. We expect to detect abnormal motion patterns, which we will quantify in measurable values (3 translations and 3 rotations of carpal bones during motion of the hand). Delineation of specific motion patterns and discriminative values of dynamic information of the carpal bones will enable us to set up new definitions for diagnosing scaphoid nonunion wrist pathologies.

Secondary

Measure	Time frame
1. The aim of rescanning patients with scaphoid nonunion after a reconstructive procedure is to investigate if these procedures have benefits for the wrist kinematics. 2. The aim by using the MHQ questionnaire before and after treatment is to evaluate if there is a correlation between the pathological kinematical pattern and the patient complaints.	—
