From: Sonographic swelling of pronator quadratus muscle in patients with occult bone injury
Sonographic images of an 11-year-old girl with a diagnosis of distal radius contusion of the left hand. Sonographic images in the longitudinal (upper image) and transverse (lower image) planes were obtained using a 17-MHz transducer. Each image shows a side-by-side comparison of the right hand (right image) and left hand (left image). The PQ of the left hand is locally thickened with hyperechogenicity on the radial side. The PQ shows a convex appearance in either hand. EP: epiphyseal plate.
