Objective and Background: There are various postulated possible causes of surgically symptomatic prolapsed intervertebral discs in the lumbar and sacral regions. They may be acting singularly or collectively. Yet, these factors have not been satisfactorily confirmed. Therefore, the continued search for predeterminants of this lesion, in males, is hereby being encouraged, and, our views are being presented. Method: From 1971 to 2009, eighty eight (88) locations of symptomatic prolapsed

... bral discs in the lumbar and sacral regions in 68 males were treated by us in Basel (Switzerland): 67, in Imo and Ebonyi States (Nigeria): 1 and none in Jamaica (West Indies). The clinical features were those of lower back pains, with or without radiation into the lower extremities, sensory loss and paresis of the limbs. There was a case of loss of urinary bladder and ano-rectal control. All lesions were confirmed through cauda-equinograms and treated under general anaesthsia in knee-chest position (MECCA position). The patients were followed for 3 to 6 months postoperatively. Results: In Basel (Caucasian population only), there were 84 locations in 67 patients, 4 locations in 1 patient in Imo and Ebonyi States (African population only) and none in Jamaica (mixed population). Their ages ranged from 23 to 70 years in Basel and the only patient in Nigeria was 67 years old. The patients all tolerated the procedures very well and there were no complications postoperatively. Conclusion: We found surgically treated symptomatic prolapsed lumbar and sacral intervertebral discs in males to have occurred more in Basel, Switzerland than in Imo and Ebonyi States of Nigeria and/or Jamaica, West Indies.
