Abstract
Aims: Presentation of modified anterior cervical discectomy by Smith- Robinson method with stabilisation by Cornerstone Carbon Cage (CCS). Methods: Since November 2001, we have been performing unique anterior intervertebral stabilisation procedures with use of carbon implants. Cornerstone Carbon Cage is an artificial intervertebral graft with empty space inside to be filled by bone chips. Cages are from 5 to 7millimetres high, with a higher anterior edge for restoration of physiological lordosis. During the operation we use typical right-side approach to vertebral column. Using intervertebral retractor we perform very wide discectomy until obtaining complete decompression of lateral recesses with exposition of joints of Luschka, which are anatomical lateral limits of the disc space. Afterwards, the wedge-shaped resection of posterior edges of the upper and lower vertebral body which are formed by osteophytes, is performed. Then, we fill the cage by bone chips and osteophytes, and using intervertebral retractor we wedge it into intervertebral space. Results: The procedure allows us to obtain the restoration of lordosis, good stabilisation of vertebral column, and additionally, through a minor distraction, procures decompression of spinal roots in intervertebral foramina. Conclusions: Through a wide intra-operational view, after discectomy and wedge-shaped resection of the vertebral body, it is possible to entirely decompress spine and nerve roots. The above modification of Smith-Robinson method creates ideal conditions for use of CCS.
