Bioactive glass has been largely reported to have perfect clinical results in the bone nonunion and fracture healing, but its effect during spinal fusion progress is rarely reported.OBJECTIVE:
To explore the safety and effectiveness of anterior cervical discectomy and fusion by cervical cage with bioactive glassMETHODS:
A total of 68 cases of cervical spondylosis myelopathy were treated with single level anterior cervical discectomy and fusion. Their clinical data were retrospectively analyzed. All the cases underwent polyetheretherketone cervical cage with autogenous bone (n=32, control group) or bioactive glass (n=32, experimental group). The bone fusion, neurological functional recovery, intervertebral height, change of cervical curve and wound complications in the two groups was recorded and analyzed.RESULTS AND CONCLUSION:
Neurological improvement had no difference between the two groups and there was no complication about wound, such as infection and delayed healing. The average rate of bone fusion was 97% in the control group while 94% in the experiment group 3 months after operation which had no significant differences. Six months after operation, all cases gained bone fusion. The intervertebral height and change of cervical curve both maintained well in the two groups within 3, 6, 12 months after operation which had no significant differences between the two groups. So, anterior cervical discectomy and fusion by cervical cage with bioactive glass is safe and effective.
