Sphincter involvement i.e urinary or bowel incontinence are bad prognostic indicators. Onset of paraplegia: Acute onset paraplegia has a better prognosis Sudden onset of paraplegia: has a bad prognosis Grades of paraplegia: On the basis of degree of motor involvement, Potts paraplegia has been divided into four grades. Grade IV is most severe and grade I is least severe. In Grade IV potts paralysis patient is unable to walk, and has paraplegia in flexion with severe muscle spasm. There is near complete loss of sensation with sphincter disturbances as already mentioned sphincter disturbances indicate poor prognosis. Prognostic factors in Potts paraplegia Complete cord involvement Late onset Longer duration 12 months Older age Healed veebral lesion Kyphotic deformity 60 degree MRI finding: Myelomalacia syringomyelia Extra edge Potts fracture: Bimalleolar ankle fracture Potts shunt: Side to side anastomosis bw the descending aoa and left pulmonary aery Potts puffy tumor: Tender puffy swelling of forehead potts puffy tumor occur in osteomyelitis of scalp bone.
