[Clinical application of MC + PEEK cage in traumatic cervical disc herniation]

To explore the clinical outcomes of surgical treatment for traumatic cervical disc herniation with MC + PEEK cage.A total of 51 patients with traumatic cervical disc herniation in mono-segment were surgically treated. The patients in group A (n = 20) were treated by MC + PEEK cage while those in group B (n = 31) by anterior cervical plate with PEEK cage or titanium mesh. Various parameters of operative duration, blood loss volume, operative complications, bone union, height of intervertebral space and Japanese Orthopedic Association (JOA) score were recorded and compared.Fifty-one patients were followed up for an average time of 26 months (range: 6 - 40). Operative duration, blood loss volume and operative complications of group A were better than group B with statistical significance (P0.05). Bone union, height of intervertebral space and recovery of spinal cord function were satisfactory with no statistical difference (P0.05).With this new cage, traumatic cervical disc herniation may be safely and micro-invasively treated without the need of anterior cervical plate.
