Abstract:
Objective To evaluate the application of SOLIS in the surgery on anterior intervertebral fusion for the treatment of traumatic cervical disc protrnsion. Methods 53 traumatic single segment cervical disc protrusion were divided into three groups randomly. The A group (SOLIS) :n=18, SOLIS filled with autocancellous bone were implanted between the cervical vertebrae. The B group(Syncage) :n =16, as the first group Syncage filled with auto-cancellous bone were implanted. The C group:n=19,anterior cervical decompression and fusion with bone autograft and internal fixation with ACPS. The operations of the surgery on anterior cervical decompression in three groups were the same. Recovery of nerve function was observed by JOA score and the fusion state, stability and changes of interver-tebra height of fusion segment were evaluated by X ray. Results The average duration of the follow-up was 16.5 months in 53 cases. Bony fusion could be found 3～9months after operation in all cases. In all A (SOLIS) group cases,the movement of the implanted $OLIS Cage were not found. The heights of the cervical intervertebral spaces and the physiological curvature were restored without loss in the duration of follow-up. The average JOA was(10.4±2.4) be-fore operation and(14.9±2.0)after operation. There was highly significant variation between the former and the latter (P<0.01). In the B (Syncage)group,5 cases had cage subsidence, therefore the height of intervertebra and the phys-iological curvature were lost. The average JOA was (10.6±2.5) before operation and (13.2±2.3) after operation.There was significant variation between the former and the latter(P<0.05). In the C group the third group, the move-ment of the fixed titanium plate were not found in the duration of follow-up in 18 cases. The titanium plate fixation was loose in 1 case. The average JOA was(10.5±2.4) bofore operation and(15.1±1.9) after operation. There was high-ly significant variation between the former and the latter(P<0.01). After operation,there was significant difference in the JOA score between the A group and the B group,between the C group and the B group(P<0.05) ,and there was no difference between the A group and the C group(P>0.05). Conclusion Treatment of single segment prolapse of the cervical intervertebral disc with SOLIS cage has some advantages such as higher fusion rate, higher recovery rate of nerve function and low rate of loss of intervertebra] height.
