There was conducted an analysis of treatment of 70 injured with associated trauma and vertical unstable fractures of pelvis. In a shock period all injured were placed the apparatus of extrafixation or forcepts. In 41 patients osteosynthesis of apparatus of extrafixation was a final method of treatment. In 29 — change of extraosteosynthesis to intraosteosynthesis in 5–7 days after trauma was made: in 13 — fixation of a ventral part, in 16 — ventral and dorsal parts.
Authors consider, that in patients with vertical unstable injuries of pelvis in associated trauma it is necessary to make the initial extra- and secondary intraosteosynthesis in 5–7 days after trauma.
