To improve extension at the radiocarpal joint in a patient eight weeks post-Colles fracture, which mobilization direction is MOST appropriate?

• A. Glide lunate and scaphoid anteriorly in relation to the radius
• B. Glide lunate and capitate anteriorly in relation to the radius
• C. Glide triquetrum and lunate anteriorly in relation to the head of the ulna
• D. Glide scaphoid and capitate posteriorly in relation to the radius

Answer: (A)

The key idea is that improving extension at the radiocarpal joint after a Colles fracture often comes down to lengthening the dorsal (posterior) structures that limit extension. Anteriorly gliding the proximal carpal row—specifically the lunate and scaphoid—on the radius effectively stretches the dorsal radiocarpal ligaments and capsule. By translating these bones toward the palm, you create a controlled stretch of the dorsal structures, allowing the joint to move farther into extension as healing progresses eight weeks post-injury. In practice, stabilize the radius, place the hand in a position near extension, and apply an anterior glide to the lunate and scaphoid with gentle oscillations or a sustained component, monitoring pain and tissue response. This approach targets the tissues most responsible for restricting extension and helps restore that motion.
