Compression of the Ulnar Nerve in Guyons Canal by Pseudotumoral Calcinosis in Systemic SclerodermaFrom the Department of Orthopaedic and Hand Surgery, Lapeyronie Hospital, Montpellier, France Correspondence: M. Chammas, MD, Department of Orthopaedic and Hand Surgery, Lapeyronie Hospital, 34295 Montpellier cedex 5, France. We report one case of ulnar nerve compression in Guyons canal due to calcium deposits in a 50-year-old woman with long standing systemic scleroderma. To our knowledge, this is the second known case. The symptoms consisted of a motor and partial sensory disturbance. Calcification of the piso-triquetral joint was prolonging into Guyons canal, lifting its contents, and into the subcutaneous tissue of the ulnar border of the wrist. Excision of calcium deposits and of the pisiform in combination with external neurolysis of the ulnar nerve resulted in complete relief of symptoms.
