Biography Historical ArticleA Tribute to William B. Long, Jr., and William B. Long, III: A Celebration of Their Revolutionary Contributions to Trauma Care.
An emergency medical system for trauma care has been conceived in our nation in an effort to improve delivery of emergency care to the accidentally injured patient. There are an estimated 20 million disabling injuries in our nation that should be cared for in trauma centers each year. This report has been written to acknowledge Dr. ⋯ Long became the Trauma Medical Director for Emanuel Hospital in the Fall of 1983. He began building Emanuel's trauma program by establishing an infrastructure that would support technically advanced ways of restoring life and function. His trauma center consisted of the following components: trauma registry, trauma resuscitation nurse program, direct to operating room policy with unstable trauma patients, anesthesia as part of the trauma resuscitation team, massive transfusion protocol, mobile surgical transport team, outreach to rural communities, recruitment of specialists with interest in trauma care, development of a new trauma physical facility, and the Physician Assistant educational program.

A biomechanical study of unilateral posterior atlantoaxial transarticular screw fixation.
The purpose of this study was to investigate the fixation of C1-C2 instability with the use of a unilateral screw. Transarticular screw placement across C1-C2 may be contra-indicated in up to 20% of specimens on at least one side because of anatomic variations or other pathological processes. Hence the current study looks into unilateral screw fixation of C1- C2 instability. ⋯ The stiffness value in flexion was 0.813 +/- 0.189 N-m/mm and in translation 67.1 +/- 25.1 N/m. It was found that stability after unilateral transarticular screw fixation was less than that previously reported after bilateral transarticular screw fixation, but similar to that found with modified Brooks posterior wiring, which has been shown to provide better stability than other posterior wiring methods, and fusion rates of 96% have been reported. We concluded that C1-C2 unilateral posterior transarticular screw fixation with supplemental posterior graft and wiring would confer adequate stability in cases where bilateral screw placement is contraindicated.
