Numbness and tingling in left fifth digit after basketball injury. Suspect hamate fracture. Evaluation of ulnar nerve neuropathy. Evaluation of the wrist is limited on some sequences by patient motion artifact. There is a minimally displaced fracture through the hook of the hamate with edema in the adjacent marrow. I see no additional fractures. Tiny rounded foci of signal abnormality within the lunate, triquetrum, and capitate, best seen on the T1 weighted sequences, are of doubtful current clinical significance.Evaluation of the intrinsic ligaments of the wrist and triangular fibrocartilage is limited by patient motion artifact and noise; given these limitations, I see no defects.The tendons of the wrist are unremarkable. There is mild edema within the soft tissues volar to the distal ulna which extends both superficial and deep to the distal flexor digitorum musculature. The ulnar nerve can be followed along its course and is unremarkable. The median nerve is unremarkable. The remaining visualized soft tissue structures are unremarkable.
Fracture through the hook of the hamate. The ulnar nerve is unremarkable.
