DISLOCATING MEDIAL TRICEPS AND ULNAR NEUROPATHY IN 3 GENERATIONS OF ONE FAMILY

Variations in the medial triceps in conjunction with bilateral ulnar n europathy have been identified in three generations of one family also possessing the phenotype of Waardenburg syndrome (a rare autosomal-do minant disorder with clinical features including cochlear deafness, dy stopia canthorum, and pigmentation problems). To our knowledge, no oth er inherited condition with triceps anomalies has been reported. Study of this family provided insight into the relationship between disloca ting medial triceps and ulnar neuropathy and demonstrated that a broad spectrum of clinical presentations exists-from being completely asymp tomatic to producing symptomatic snapping and ulnar neuropathy.
