Abstract:

26 cases of fracture of sacrum in this series of 50 patients with double vertical fracture-dislocation of pelvis were analysied in respect of their fracture patterns. They constituted 52% in this series and appeared in various types. Taking account of fracture line and direction of dislocation, it is clear that sacral fracture is a result of continuatton of the force causing the pelvic fracture-dislocation. It has been shown thaf the incidences of severe shock, viserel injury, fracture and dirlocaion of extremity were much more common in patients with sacral fracture than those without. 18 cases, 78.2%, of the patients with sacral fracture in this series, had lumbosacral nerve injury, while none of the other 24 patients without sacral fracture experienced nerve injury. Thus sacral fracture is the main cause of damaging the nerve. Severe as it be, sacral fracture and nerve injory need not specific management. For treatment, general condition of the patient is still of utmost importance and the pelvic fracture-dislocation ought to be traeted as a whole.
