The idiopathic dystonias. A note on their orthopaedic presentation

Eight patients suffering from various forms of idiopathic dystonia are described whose initial referral was for an orthopaedic opinion. The diagnoses of these patients, who were seen over a two-year period, comprised dystonia musculorum deformans, dystonia of the foot, spasmodic torticollis and occupational cramps. Although various musculoskeletal sequelae often occur, the primary underlying neurological cause of these unusual conditions is emphasised.
