Objective:This study is designed to evaluate the fusion rate of anterior cervical discectomy and fusion (ACDF) using prefilled cage, and clinical features in patients with traumatic cervical injury.
Methods:Sixteen trauma patients at a single institute who underwent ACDF with prefilled cage and rigid plate fixation were evaluated for radiographic fusion status postoperatively every 1 month, 3 month, and 6 month after the surgery. ACDFs were done in 9 patients at one level, 3 patients at two levels, 3 patients at three levels, and 1 patient at four levels. Fourteen patients had fracture and instability, and 2 patients had traumatic herniated cervical discs without fracture and instability. Plain radiographs and CT scan were done for evaluation of bone fusion in all patients.
Results: Bone fusion was recognized in all patients. Intervertebral disc height was well maintained during follow-up period. There was no patient with graft failure and instability. Even though the patients with fracture and instability, there was no patient who needed posterior stabilization. There was one case of subsidence without clinical symptom which was needed additional surgical treatment.
Conclusions:In the treatment of the patients with traumatic cervical diseases, prefilled cage is very effective to achieve cervical spinal stability after ACDF, and to maintain intervertebral disc height. We can achieve immediate postoperative stability and prevent graft displacement by reinforcement with cervical plate and screws.
