Abstract

The purpose of this study was to compare anterior cervical discectomy and fusion with cage alone (ACDF-CA) and anterior cervical discectomy and fusion with cage and plate (ACDF-CP) with regard to adjacent segment degeneration (ASD) diagnosed by the use of CT and MRI with retrospective matched cohort design. This study enrolled 68 patients who underwent single-level ACDF who were diagnosed with cervical degenerative disc disease and were followed up for at least 2 years with plain radiographs, computed tomography, and magnetic resonance imaging. The patients were divided into 2 groups according to the operation method: ACDF-CA (33 patients) and ACDF-CP (35 patients). ASD occurred in 4 of 33 patients who underwent ACDF-CA and 9 of 35 patients who underwent ACDF-CP as determined by computed tomography and magnetic resonance imaging. The upper segment range of motion and lower segment range of motion increased in both groups postoperatively. The increase was greater in the ACDF-CP group without statistical significance. The upper segment disc height and lower segment disc height gradually decreased in both groups over time. The decrease was significantly greater in the ACDF-CP group at each follow-up visit. Pseudarthrosis and cage ...Continue Reading

Birth Defects

Birth defects encompass structural and functional alterations that occur during embryonic or fetal development and are present since birth. The cause may be genetic, environmental or unknown and can result in physical and/or mental impairment. Here is the latest research on birth defects.

Autism

Autism spectrum disorder is associated with challenges with social skills, repetitive behaviors, and often accompanied by sensory sensitivities and medical issues. Here is the latest research on autism.
