Abstract EN
Shape memory alloy (SMA) staples in nickel titanium with shape memory effect are effective for spinal growth control.
This study was designed to evaluate the biomechanical properties of the staples and observe the stability of the fixed segments spine after the staples were implanted.
According to the vertical distance of the vertebrae, SMA staples of 5, 6.5, and 8 mm were designed.
The recovery stress of 24 SMA staples in three groups was measured.
The pullout strength of SMA staples and stainless steel staples in each functional spinal unit was measured.
Each of the six fresh specimens was divided into three conditions: normal, single staple, and double staples.
Under each condition, the angle and torque of spinal movements in six directions were tested.
Results show that the differences in recovery stress and maximum pullout strength between groups were statistically significant.
In left and right bending, flextion, and extention, the stability of spine was decreased in conditions of single staple and double staples.
Biomechanical function of SMA staples was superior to stainless steel staple.
SMA staples have the function of hemiepiphyseal compression and kyphosis and scoliosis model of thoracic vertebrae in goat could be successfully created by the fusionless technique.
