Pronator quadratus sign

Case contributed by Dr R Mannava

Presentation

Wrist pain after fall from 12 feet.

Patient Data

Age: 12
Gender: Male
Modality: X-ray

Displacement and anterior bowing of the fat pad overlying the pronator quadratus muscle, subtle widening of the distal radial physis, and a lucent line along the dorsal distal radius extending into the physis are suggestive of Salter Harris II distal radius fracture.

Case Discussion

Pronator quadratus sign, or anterior displacement of the volar fat pad overlying the distal radius and ulna can be an important clue to an occult wrist fracture.
