Female 49 years old Reason: Evaluate loose fragment/cyst at scaphoid History: Pain after fall 2 days ago BONES: There is a comminuted, essentially nondisplaced, intra-articular fracture of the distal radius consisting predominantly of a transverse fracture plane with longitudinal extension to the articular surface proximal to the lunate. The ulnar styloid appears intact. A subcentimeter triangular focus of low signal intensity is situated dorsal to the distal pole of the scaphoid and proximal to the trapezoid bone corresponding to a small mineralized fragment seen on outside radiographs perhaps reflecting sequela of old trauma. We see no acute fracture of the scaphoid or of the other carpal bones.Mild osteoarthritis affects the basilar joint. A small focus of signal abnormality in the proximal lunate may represent a cyst or bone contusion.LIGAMENTS: Evaluation the scapholunate and lunotriquetral ligaments is limited due to lack of intra-articular contrast but we see no findings to suggest a tear.TRIANGULAR FIBROCARTILAGE COMPLEX: There is mild heterogeneity of signal intensity of the lamina and adjacent articular disc of the triangular fibrocartilage which may reflect degeneration but we see no fluid traversing the articular disc to indicate an acute tear.TENDONS: There is a bifid abductor pollicis longus which may be a normal variant. There is a small amount of fluid surrounding the extensor pollicis longus tendon as it crosses the second dorsal compartment tendons, this has been described in association with distal radius fractures.ADDITIONAL
Nondisplaced, comminuted, intra-articular fracture of the distal radius and other findings as described above.Findings were discussed by phone with Dr. Birnie at 09:31 on 6/1/2016.
