ABSTRACT
Pyogenic discitis most frequently occurs after home delivery, hemorridectomy, and dilatation and curettage. Discitis is generally due to blood borne bacterial invasion of the disc from adjacent end-plate via communicating vessels. Infective discitis remains an uncommon, but potentially serious cause for back pain. Delayed diagnosis can occur and a high index of suspicion may occur. The study included 30 patients suffering from localized low back pain with limitation of movement. Diagnosis was made by history, physical examination and investigation mainly E.S.R and MRI. 50.3% of patient with discitis had a history of vaginal delivery, 15% had a history of hemorridectomy and 10% had a history of dilatation and curettage and cesarean section surgery. All patients had elevated E.S.R, Positive C-reactive protein and positive MRI finding. We must think of Pyogenic discitis in any patient with sever backache, fever, local tenderness, and high ESR
