Application of lumbo-iliac fixation in pelvic ring reconstruction following communited Denis Ⅲ sacral fractures / 中华创伤杂志

ABSTRACT

Objective To study the anatomic morphology of posterior column of ilium(PCI)and valne of lumbo-iliac fixation(LIF)in pelvic ring reconstruction following communited Denis Ⅲ sacral fractures.Methods A total of 17 hemi-sectional pelvis and dry ilia were selected to observe the length,width and height(safety and standard)of PCI,when a detailed description was done on the methods determining entry point and operation techniqus for iliac screws anchoring.Nine patients with eommunited sacral fractures involving Denis Ⅲ areas combined with neurologic deficits were decompressed for recovery of neurological function and reconstruction of pelvic ring by using LIF.Postoperative follow-up was done on role of LIF and result of neural rehabilitation.Results PCI was mean 110.57 mm in length,24.24 mm in width,14.54 mm in standard height and 31.46 mm in safe height.Nine patients could turn over in bed immediately following operation and walk one month later.A follow-up for 13-37 months in eight patients showed stable reconstructed pelvic ring,sound function of movement and bone graft fusion,which met the target of keeping stability of fractured extremity and pelvis.Conclusions pCI can provide anatomic support for LIF.When decompression and fixation is needed for sacral fractures combined with anterior pelvic ring disruptions,LIP can provide stable fixation and play an important role in reconstruction,nursing and rehabilitation of pelvic ring.
