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.
