Radiocarpal Contact Mechanics

Of primary interest in scapholunate ligament tears are the mechanics of the radiocarpal joints. As the bones separate radiocarpal cartilage is loaded in new areas and often with higher pressures. These changes can lead to arthiritis and further collapse of this joints.

Biochemical Assessment of Cartilage

The objective of this study is to evaluate changes in the biochemical status of the cartilage in the wrist following scapholunate ligament injury by analyzing the T2 relaxation time in the cartilage of human subjects. Our hypothesis is that the calculated T2 relaxation time will be higher in the cartilage of injured wrists than in that of contralateral (uninjured) controls.

Mid-Carpal Contact Mechanics

Our group is also looking at important mid-carpal mechanics with scapholunate ligament tear. The capitate is the central bone of the wrist and articulates with both the scaphoid and lunate. How does S-L ligament tear affect these joints?

Distal Radioulnar Contact Mechanics

The distal radioulnar joint is not part of the wrist proper, but is a forearm joint. In vivo mechanics of this joint have not been characterized, and we are gathering that data. Also, how does scapholunate ligament tear affect this joint?
