Anterior cervical Cage-assisted fusion combined with locking titanium plate internal fixation for the treatment of extension-type cervical fracture / 中国组织工程研究

ABSTRACT

BACKGROUND:There is no literature about the treatment according to the mechanism of cervical spine injury classification, especial y for the treatment of extension type cervical fracture/dislocation with merger cases of posterior composite structure damage, whether simple anterior approach can meet the needs of the treatment has no detailed elaboration. This article may analyze from the aspect of cervical spine injury mechanism. OBJECTIVE:To observe the short-term effect of anterior cervical Cage-assisted fusion combined with locking titanium plate internal fixation for the treatment of extension type cervical fracture. METHODS:A retrospective analysis was performed in 15 extension type cervical spine fracture dislocation patients treated with decompression anterior cervical intervertebral disc resection plus bone graft with cage-fusion locking titanium plate internal fixation from June 2006 to March 2011 in the Department of Orthopedics, Xianning Central Hospital, including 10 cases of single segment injury and treatment, and five cases of multiple segment injury and treatment. Japanese Orthopaedic Association score and the neck disability index were compared before and after treatment;the cervical flexion and height were measured according to the antersposterior X-ray film taken before fixation, 1 week after fixation and final fol ow-up.RESULTS AND CONCLUSION:The patients were fol owed-up for 8-37 months. One case had Cage mild sinking and shift, and there was no internal fixation breakage or loosening in al the patients. Transient pharyngeal discomfort was observed in 11 patients. Compared with the preoperation, the Japanese Orthopaedic Association score, neck dysfunction index, fusion segment cervical flexion and fusion segment intervertebral disc height were significantly improved at 1 week after fixation and final fol ow-up (P0.05). The short-term effect of decompression anterior cervical intervertebral disc resection plus bone graft with cage-fusion locking titanium plate internal fixation for the treatment of extension-type cervical fracture is good.
