Treatment of Gustilo grade III leg fractures by external fixation associated with limited internal fixation / 中华创伤杂志(英文版)

ABSTRACT

<p><b>OBJECTIVE</b>To explore the clinical effects of external fixation associated with limited internal fixation on treatment of Gustilo grade III leg fractures.</p><p><b>METHODS</b>From July 2006 to December 2008, 40 cases of Gustilo grade III leg fractures were emergently treated in our unit with external fixation frames. Soft tissue injuries were grouped according to the Gustilo classification as IIIA in 17 cases, IIIB in 13 cases, and IIIC in 10 cases. All the patients were debrided within 8 hours, and then fracture reposition was preformed to reestablish the leg alignment. Limited internal fixation with plates and screws were performed on all the Gustilo IIIA cases and 10 Gustilo IIIB cases at the first operation. But all the Gustilo IIIC cases and 3 Gustilo IIIB cases who had severe soft tissue injuries and bone loss only received Vacuum-sealing drainage (VSD). Broad-spectrum antibiotics were regularly used and VSD must be especially maintained easy and smooth for one week or more after operation. Limited internal fixation and transplanted free skin flaps or adjacent musculocutaneous flaps were not used to close wounds until the conditions of the wounds had been improved.</p><p><b>RESULTS</b>The first operations were completed within 90-210 minutes (170 minutes on average). The blood transfusions were from 400 ml to 1500 ml (those used for anti-shock preoperatively not included). All the 40 patients in this study were followed up for 6-28 months, 20.5 months on average. The lower limb function was evaluated according to the comprehensive evaluation standards of leg function one year after operation and the results of 28 cases were excellent, 9 were good and 3 were poor.</p><p><b>CONCLUSION</b>External fixation associated with limited internal fixation to treat Gustilo grade III leg fractures can get satisfactory early clinical therapeutic effects.</p>
