title: Analysis of chosen strength factors of spine and spine-fixator set.
abstract: The paper presents chosen results of research on the lumbar-chest part of spine and the spine-fixator complex. Spines were gathered from cadavers. Both damaged and undamaged spines with and without fixator were investigated. Two types of fixator were used: a CD and a modified Zespol fixator (our idea)--marked as P. In the research, compression/distraction forces were applied. The analysis is based on the results of comparative calculation: load range, hysteresis loop area and neutral zone stiffness.
