29-year-old male status post ski injury. Evaluate left ring finger extensor tendon injury, evaluate left proximal phalanx fracture. LIGAMENTS: Ligaments appear intact.TENDONS: The extensor tendon of the left ring finger is not visualized in its entirety, specifically the course of the extensor tendon abruptly terminates at the level of the proximal phalanx, with surrounding edema suspicious for a tear. The extensor tendon of the remaining imaged fingers appear normal. There is fluidlike signal within the tendon sheath of the flexor compartment overlying the metacarpal of the ring finger. However the flexor tendons of the ring finger appear normal and intact throughout their course. Similarly the flexor tendons of the remaining imaged digits appear normal.BONES: Obliquely oriented low T1, low T2 signal along the proximal phalanx of the ring finger compatible with nondisplaced fracture, better seen on recent radiograph. There is surrounding bone marrow edema. There is a small amount of fluid within the metacarpophalangeal joint of the ring finger. Bone marrow signal in the remaining fourth finger and other imaged digits appears normal.ADDITIONAL
1. Findings suspicious for a tear of the extensor tendon of the left ring finger.2. Left ring finger proximal phalanx fracture is again seen and better evaluated on recent dedicated radiograph. Other findings as described above.
