    Title Fixation Strength of Unicortical Versus Bicortical C1-c2 Transarticular Screws.
    Date September 2008
    Journal The Spine Journal : Official Journal of the North American Spine Society

    BACKGROUND CONTEXT: The internal carotid artery and hypoglossal nerve lie over the anterior aspect of the lateral mass of the atlas and are at risk from bicortical C1-C2 transarticular screws. This has led to the recommendation for unicortical screws if the neurovascular structures are in close proximity to the proposed exit point. No data are available on strength of unicortical versus bicortical C1-C2 transarticular screws. PURPOSE: To compare the biomechanical pullout strength of unicortical versus bicortical C1-C2 transarticular screws in a cadaveric model. STUDY DESIGN: Biomechanical study. METHODS: Fifteen cervical spine specimens underwent axial pullout testing. A unicortical C1-C2 transarticular screw was placed on one side with a contralateral bicortical screw. Data were analyzed to reveal any significant differences in strength. RESULTS: Mean pullout strength for the bicortical C1-C2 transarticular screws was 1,048.8 (+/-360.1) N versus 939.2 (+/-360.6) for unicortical screws (p=.22). There was no significant difference in the pullout strength of unicortical and bicortical screws. CONCLUSIONS: In cases with satisfactory bone quality, it appears reasonable to use unicortical screws to avoid the risk of neurovascular injury from penetrating the anterior cortex of C1.

    Title Treatment of Field Water with Sodium Hypochlorite for Surgical Irrigation.
    Date October 2004
    Journal The Journal of Trauma

    BACKGROUND: Early irrigation and surgical debridement of high-energy wounds and open fractures effectively prevents infection. Rapid wound care has been maximized by the United States military's "forward surgical teams." However, the volume of sterile irrigant required to treat multiple patients with multiple wounds presents a significant logistical burden. Using ground-derived field water could eliminate this burden. METHODS: We collected 100 water samples from five sources. An initial bacterial count (CFU/mL) was determined before treatment. 5% sodium hypochlorite was then added to each sample to derive a concentration of 0.025%. After treatment, a final bacterial colony count was performed. RESULTS: We found no bacterial growth in 99/100 samples. One post-treatment sample grew a single colony of a Bacillus species not present in the pretreatment culture and was determined to be an air contaminant. CONCLUSIONS: Our field-expedient modification of Dakin's solution could substitute for sterile irrigation fluid when it is neither available nor logistically feasible.
