Complications associated with cervical vertebral body replacement with expandable titanium cages

This study aimed to explore the safety and efficacy of using nano-hydroxyapatite/polyamide (N-HA/PA) composite in anterior cervical vertebral body subtotal corpectomy and interbody fusion. Total 50 patients with cervical spondylotic myelopathy were enrolled to undergo anterior cervical spondylectomy. Bone graft pedicles were compounded with N-HA/PA and intervertebral body fusion was performed. Study outcomes included surgical efficacy and the degree of fusion. Patients in whom vertebral body fusion was performed with N-HA/PA composite pedicles had significantly improved symptoms. The postoperative Japanese Orthopaedic Association scores increased to 18.56±4.37 from 11.37±3.52, reflecting an improvement rate of 87.3%. The composite pedicle fusion rate was 96.4%. Therefore, N-HA/PA composite pedicle as a bone graft material in fusion surgery provides significant therapeutic efficacy. Moreover, the composite pedicle fusion rate is high, making it ideal for anterior cervical vertebral body subtotal corpectomy and fusion.

Cervical Vertebral Body

The branch of orthodontics has had an interest in the cervical vertebrae wherein cervical spine is used as a reference structure for natural head position, so skeletal age was evaluated by studying variations in the cervical vertebral morphologies. Among all evaluations, very limited data is available wherein comparison between cervical vertebral body volumes between the different malocclusions has been done. This study aimed to compare the differences in the volumes of cervical vertebral bodies of C2, C3, and C4 between skeletal class I and class II malocclusions of both horizontal and vertical growth patterns. In class I the volume was significantly lesser as compared to class II. It was seen that there was statistically no significant difference in the volume between the horizontal and vertical growers. It can be concluded from this study that cervical vertebral body volume has no effect on growth pattern. However, variations in cervical vertebral body volume are seen with different malocclusions.
