Systemic scleroderma associated with bilateral ulnar nerve entrapment

Description: Peripheral nervous system involvement in systemic sclerosis (SSc) is rare, and is usually limited to carpal tunnel syndrome. Ulnar nerve involvement secondary to compression of Guyon's canal has been reported in two patients. Herein, we describe for the first time an SSc patient who developed bilateral ulnar nerve sensorimotor compression at the elbow and improved markedly after neurolysis and surgery.
