ABSTRACT
PURPOSE:
To introduce a novel transverse connecting screw system, and to evaluate the biomechanical stability of the novel screw system using human cadaveric specimens.METHODS:
Six fresh-frozen cadaveric upper cervical spines were used in our study. Every specimen was tested under 5 conditions intact group; unstable group; C1 to C2 screw rod system group; C1 to C2â +â crosslink system group; atlas polyaxial transverse connecting screw (APTCS) system.RESULTS:
Compared with the intact state, C1 to C2 screw rod system, C1 to C2â +â CL system and APTCS showed statistically decrease range of motion in all directions except for the unstable group under posterior extension direction (Pâ <â .05). APTCS group has the least range of motion in all directions (Pâ <â .001).CONCLUSION:
The APTCS system was able to restore stability to the atlantoaxial joint. APTCS system has the advantages of easy installation, convenient bone grafting, and strong biomechanical strength.
