The voluminous literature and the host of new instruments and techniques used, in cases with deformed or unstable spines, all emphasize the fact that the ideal corrective technique and instrument is still elusive. In part, this is because in the spine, the same fixator may be called upon for contradictory physical force vectors such as compression and distraction, at the same time or at different times. Also, a fixator which is an ideal load distribution system at rest may become inadequate on bending or rotation. Hence a spinal fixator should be adaptable and capable of being tailored to suit the needs. A review of the current literature has been done to highlight such problems in spinal instrumentation. A preliminary report is also made on an indigenously developed adaptable spinal fixator.
