Where in the wrist can somatic dysfunctions occur?

• A. Minor gliding motions of flexion/extension or abduction/adduction of the true wrist
• B. Between Individual Carpal Bones
• C. At the Radiocarpal Joint Only
• D. At the Midcarpal Joints

Answer: (A)

The wrist’s somatic dysfunction is tied to the places where the principal gliding motions occur. The true wrist refers to the radiocarpal articulation, where the distal radius meets the proximal carpal row. As you flex/extend and move the wrist side-to-side (abduction/adduction), the carpal bones glide on the radius in small, subtle motions. When these glides become restricted or abnormal, a somatic dysfunction is present. This location is the best fit because it directly describes the primary arthrokinematic site of wrist motion. Intercarpal joints (between individual carpal bones) and midcarpal joints can contribute to wrist movement, but the classic focus for somatic dysfunction in this context is the radiocarpal glide at the true wrist.
