Document Summary
Behaviour-based classi cation systems for tbi severity: a generally accepted classi cation based on the presence, degree, and duration of coma, the glascow. Table 7. 1 diagnostic criteria for mild tbi by the american congress of rehabilitation medicine. Penetrating head injuries: often, bone fragments associated with penetration and shattering of the skull are also driven into the brain, the fragments producing widespread damage, as shown in figure 7. 4. Figure 7. 4 (left) day of injury (doi) initial ct scan prior to neurosurgery depicting the trajectory and path of a bullet injury to frontotemporal areas of the brain. Bullet entrance is in the region of the left temple. Shattered bone fragments. (right) one month postsurgery, a right frontal craniotomy is apparent (absence of skull) with multiple retained bone fragments mostly in the left temporal area, but some extending into the posterior frontal. Note the expansion of the ventricular system, an indication of cerebral atrophy.
