Article Synopsis
- This study evaluates how different vertebral distraction-fusion techniques affect adjoining cervical vertebrae in dogs, specifically the C5-C6 and C4-C5 segments.
- Ten Beagle cervical vertebrae were tested using three stabilization methods (intact, titanium plate, and PMMA), with biomechanical assessments measuring range of motion (ROM) during various movements.
- Results indicated that both fusion techniques altered the mechanical behavior at adjacent vertebrae, with significant variations in ROM based on the method used, which suggests potential for adjacent segment disorders.
Hydroxyapatite (HA)/poly-l-lactide(PLLA) composite biomaterials are available for orthopedic applications, but bioresorption and cell-mediated inflammation in bone cortex are unknown. We conducted an 84-month follow-up study with Beagle dogs that were subjected to implants with either PLLA (left femur) or HA/PLLA (right femur). Histological and radiographic analysis showed that HA/PLLA screws induced significant increases in HA content from 36 months onward and complete burr hole closure at 60 months, whereas PLLA screws did not.
