Inclusion criteria
In order to be eligible to participate in this study, a subject must meet all of the following criteria:
- Patients with a one-sided palmar and dorsal scapho-lunate ligament reconstruction after traumatic rupture with a maximum
follow up of 5 years.
- Patients are over the age of 16 years
- Patients who are willing and able to give informed consent
Exclusion criteria
A potential subject who meets any of the following criteria will be excluded from participation in this study:
- Surgical history of the carpus
- A history of trauma (treated with a cast or surgically) to the contralateral non-fractured wrist
- Not able to understand the written informed consent
- Pregnancy
- (Peri-)lunar dislocation
- Pain, to the degree that the patient is not able or willing to move the hand

- Primary Outcome Measures
Name Time Method Primary study parameters/outcome of the study:<br>The aim is to gain dynamic information (motion patterns) of the scaphoid relative to the lunate. 3- Dimensional movement is<br>divided in six parameters. For comparison of the scaphoid relative to the lunate, twee mean parameters (rotation and translation)<br>have to be calculated. For these experiments the apparent changes in position of the fragments with respect to each other are<br>displayed as a rotation around a Helical Axis of Motion (HAM) and translations along the HAM. Our aim is to determine a standard deviation of motion<br>of the scaphoid and lunate using a 95% confidence interval.
- Secondary Outcome Measures
Name Time Method Secundary study parameters/outcome of the study (if applicable):<br>For analysis of the wrist joint, every motion (HAM), 3 translations parameters and 3 rotation parameters of the carpal bones will<br>be defined in relation to radial positioning. Comparison of the operated and contralateral wrist of every patient will be made. The<br>expectation is that there is a significant change in dynamic of the carpal during motion of the wrist after combined scapholunate<br>reconstruction. The hypothesis is that the volar reconstruction is not physiological.
