[Therapy of unstable sacrum fractures in pelvic ring. Results of of osteosynthesis with early mobilization].

Eight patients with sacrum fractures combined with pelvic ring fractures type C were treated using a triangular osteosynthesis after reduction of the fracture. The additional vertical stabilization between the lumbar spine and the posterior iliac crest caused the stability, which is necessary for immediate mobilization of patients. Perfect reduction, correct positioning of the hardware, gentle soft tissue treatment, as well as early mobilization of the patient, increases the early and late prognosis considerably, and compensates the operative trauma completely. We observed no infections or redislocations. The described operative treatment is state of the art at our institution.
