Insertion of PCB to treat traumatic cervical intervertebral disc herniation

Objective: To evaluate the clinical effect of PCB (a new anterior cervical instrumental system combining an intradiscal cage with an integrated plate) in treating traumatic cervical intervertebral disc herniation. Methods: Anterior decompression and PCB internal fixation were used in 22 patients with traumatic cervical intervertebral disc herniation. They were followed up from 3 to 16 months and analyzed by symptom and image data. Among them, 16 patients underwent fixation at one level and 6 patients at two levels. Results: This technique did not cause intraoperative complications. After surgery no screw backout or device failure was found. Based on the JOA grade, 20 patients improved clinically and 2 gently because of serious cervical stenosis. The general excellent rate was 90.9 %. Conclusions: PCB internal fixation is stable. Morbidity of donor and acceptor sites is less. No collars are needed after surgery.
