Multiple morphologic parameters were studied in 50 normal adult vertebral columns ranging in age from 20 to 40 years at the time of death. Posterior element morphology is highly variable and largely unpredictable. Minimum pedicle diameters ranged from 1.8 mm at T6 to 6.4 mm at L5, and did not correlate with any more readily measured vertebral dimensions.(More)
Systemic effects such as anesthesia, hypotension, hypothermia, and hypoxia affect the cortical evoked responses. We propose, that by sequential stimulation of the median and posterior tibial nerves, and the construction of a ratio from the value of their amplitudes, the systemic effects can be eliminated and thus improve the reliability of the cortical(More)
