Anterior Interbody Fusion Combined with Anterior Cervical Plate Fixation in Cervical Spine Injury

The anterior interbody fusion combined with internal metal plate fixation was performed from January, 1988 in seven patients with unstable mid and lower cervical spine. The insertion of the metal plate was simple and maintained the block bone graft in satisfactory position. We concluded from this early follow-up that, this alternative method of internal fixation of cervical spine allowed not only effective stabilization for the unstable spine but also early mobilization and short hospital stay.

A Study on Regional Cerebral Blood Flow of Normal Adults

The values for regional cerebral blood flow at rest were obtained from 60 right handed normal Korean adults(48 males, 12 females) with an age range of 24 to 69 years. The results were summarized as follows. 1) Mean rCBF were Fg ; 74.8+/-13.3ml/100g/min., Fw ; 19.2+/-3.1ml/100g/min, Wg ; 44.0+/-5.4% and CBF(inf) ; 39.8+/-7.6ml/100g/min. 2) In normal regional flow distributions throughout each hemisphere, values of Fg, Fw and CBF(inf) were higher in the frontal lobes and lower in the parietal lobes. A trend for higher values for Wg was seen in occipital and temporal lobes and lower values in the frontal lobes of both hemispheres. 3) When normal limits of the interregional variety values were predicted as mean ICV+2 SD(p<0.05), those values were Fg ; 12%, Fw ; 12%, CBF(inf) ; 10%, FFg ; 4% and Wg ; 10% of mean hemispheric rCBF. 4) There was a significant progressive decline of parameters of Fg, CBF(inf) and Wg with advancing age.
