ObjectiveTo present the technique for percutaneous placement of cannulated screws in the iliac wing, and to describe the surgical technique and the methods, the indication, the time, the key of operation and the clinic outcomes of the technique.MethodsThrough the anatomy study of ilium, a wider columns structure at the posterior ilium was found, which was named "the posterior columns of pelvis", and then measure the parameter of the structure. Twelve patients with the injuries in the iliac wing and the anterior ring of pelvis were treated with percutaneous cannulated screws internal fixation.ResultsAll of the fractures healed in the followed up period. Vertical replacement were all completely corrected. Two of the cases left behind slight rotary replacement, and no complication were found.ConclusionsThe technique of percutaneous cannulated screws internal fixation for treating the posterior portion of the iliac wing fractures has the advantages of small trauma, less bleeding stiff fixation, which is an ideal and minimally invasive technique.
