Treatment of femur fracture with associated vascular injury.

OBJECTIVE

The aim of this study was to determine (1) if internal fixation was associated with a high amputation rate in patients with femur fracture and vascular injury; and (2) if patients who underwent internal fixation before vascular repair had a higher amputation rate.

DESIGN

This is a retrospective analysis.

MATERIALS AND

METHODS

Twenty-six patients requiring femoral stabilization with injury to the superficial femoral artery, popliteal artery, or common femoral vein were studied. The Injury Severity Score and the Mangled Extremity Severity Score were calculated for each. Nineteen patients underwent internal fixation. Ten patients had internal fixation before vascular repair.

RESULTS

Sixteen of 19 patients treated with internal fixation had limb salvage. Nine of 10 patients who had internal fixation before vascular repair had limb salvage. Poor outcomes (gangrene, amputation, or death) were associated with a Mangled Extremity Severity Score > or = 6 (p = 0.005).

CONCLUSIONS

In these patients, poor outcome is associated with severe leg injury, (with a Mangled Extremity Severity Score of > or = 6). Internal fixation can be safely used, and skeletal stabilization can be safely performed before vascular repair. If ischemic time is prolonged, vascular shunts should be used until skeletal stabilization is completed.
