In radiocarpal distraction joint mobilization, what is the direction of the force applied by the force hand?

• A. Longitudinal Toward
• B. Medial
• C. Lateral
• D. Longitudinal Away

Answer: (D)

When performing radiocarpal distraction, the goal is to separate the joint surfaces to increase joint space and allow for smoother gliding. The force is applied along the long axis of the forearm, pulling the distal carpal row away from the radius. This longitudinal distraction creates true joint separation rather than folding or shearing the bones.

Applying a longitudinal force toward the joint would compress the surfaces, and directing the force medially or laterally would glide the carpal bones side to side rather than split the joint space. So the correct approach is a longitudinal pull away from the wrist, creating distraction.
