ABSTRACT
Background: The objective of this study is to illustrate the impact of disc prosthesis instrumentation in the intervertebral disc space following discectomy on cervical lordosis (CL) as observed in radiographic images, with measurements of Cobb angle and cervical disc height taken before and after surgery. Furthermore, the study seeks to elucidate the functionality of the disc prosthesis employed.
Objective: The objective was to illustrate the functionality of the surgical procedure and the disc prosthesis employed, with a comparison of pre- and postoperative measurements.
Methods: A total of 106 patients with cervical disc herniation who underwent surgical intervention using cervical disc prosthesis were included in the study. Pre- and post-surgical lateral direct radiographic evaluations were conducted on each patient. The following variables were recorded for each patient: preoperative Cobb angles, cervical disc height, surgical level, age, and gender.
Results: The operating level was most frequently at the C5-6 level. There was a significant increase in the cervical Cobb angle after surgery, as well as a significant increase in postoperative disc height in comparison to preoperative values. The change in Cobb angle and disc height was found to be statistically significant (p < 0.05).
Conclusion: A variety of cervical interbody grafts are currently in use. The use of cervical disc prostheses in cervical disc herniation surgery allows for the achievement of optimum lordotic angulation. There is a continued need for new studies to support the findings of physical examinations and for long-term clinical follow-ups in the field of neurosurgery, particularly in relation to anterior cervical discectomy and fusion techniques.
