Abstract
In the development of new strategies for different spine fixation methods, new
methods must be tested biomechanically under in vitro conditions before clinical
trials can be performed. The effect of different conservation mode on the
mechanical properties of vertebrae is an important question. The aim of our
research was to determine the effects of three different conservation methods
(fresh, no conservation – F; fresh-frozen – FF, alcohol-glycerin-fixation – AG;
cooling-storage – CS). 100 swine vertebrae (Th4-Th8) were dimidiated into two
specimens. These 200 specimens were assigned to four different groups. After
conservation, the Young modulus and compressive strength were determined and
compared to the same properties of fresh specimens. After 48-hour cooling the
Young modulus and the compressive strength decreased by 39%. After 27-day
freezing the Young modulus and the compressive strength decreased by 5%.
After 27-day storage in ethyl-alcohol the Young modulus decreased by 12% and
the compressive strength increased by 57%. The different conservation methods
significantly influenced the mechanical properties of swine vertebrae.
Mechanical properties were influenced less by frozen storage, so this type of
storage is recommended for the conservation of vertebrae.
Keywords: conservation method, vertebrae, compressive strength, young
