OBJECTIVE: Reporting clinical and electrodiagnostic characteristics of
sport-related ulnar neuropathies at the wrist. METHODS: Eight
sport-related and 45 non-sport-related cases from 53 ulnar neuropathies at the
wrist cases over 14 years. RESULTS: Sport-related ulnar neuropathies at the wrist
cases were due to cycling (5 cases), kayaking (2 cases), and big-game fishing (1
case). No patient had sensory complaints in ulnar digits, and all had motor
impairment. Conduction across the wrist with recording on the first dorsal
interosseous muscle was impaired in all cases, with conduction block in 5. Two
cyclists showed bilateral ulnar neuropathies at the wrist. All cases recovered
within 2 to 6 months with sport discontinuation. Distal lesions of the deep motor
branch were more frequent in sport- than non-sport-related cases. CONCLUSIONS:
The 8 sport-related ulnar neuropathies at the wrist cases involved the deep motor
branch. Conduction study to the first dorsal interosseous muscle across the wrist
is the key to electrodiagnostics. Bilateral cases in cyclists does not require
wrist imaging.
