Regarding Sudeck's osteodystrophy all are true except:
Burning pain
Stiffness and swelling
Erythematous and cyanotic discolouration
Self limiting and good prognosis
(d) Self limiting and good prognosis- Recovery is prolonged and painful both for patient and surgeon. 3 years usually elapse before the bones are remineralized and it is rare that full range of movements returns.
