Abstract
Purpose
The aim of this study is to investigate the outcome of these limb-threatening injuries through external fixation treatment and to discuss the case of patients’ functional recovery after external fixation.
Methods
Demographics, surgical treatment and outcomes in 88 patients with lower leg arterial injuries treated by external fixation at two trauma centers from 2009 to 2018 were reviewed. The primary outcome was the rate of successful lower leg salvage, while secondary outcomes were complications and functional recovery.
Results
Eighty-eight patients were identified and 80 patients (90 legs) maintained a successful lower leg salvage. The mean age was 32.7 ± 10.8 years, and 81.8% were male. The primary outcomes included the following complications: pin-tract infection (8 legs), pins loosening (4 pins), wound superficial infection (7 legs), deep infection developed osteomyelitis (3 legs), bone nonunion or bone defect (17 legs) and amputation (8 legs). The average healing time of fracture was 5.6 ± 4.3 months. The maintain of external fixation average time was 5.8 ± 3.6 months. The improvement of scores of the pain, function and quality of life in our follow-up was statistically significant.
Conclusion
For the lower extremity fracture patients with vascular injuries, using external fixation correctly can improve clinical outcomes and produce the improvement of pain, function and the quality of life.
Level of evidence
Retrospective cohort, level IV.
The success rate of the lower leg salvage is high, reach the percentage of 91.8% (90/98).
External fixation is less invasive, with achieving adequate stability to repair the arterial injury timely, can lower the ischemic time, and beneficial for the following bone or soft tissue repair.
Treating the patients with external fixators timely is beneficial to the following vascular anticoagulation, bone defect and vein graft, as a result, the protection of lower limb can be improved.
