Description
Summary:Purpose is to evaluate the results of resection of hernia cervical disc with and without cage fusion. Material and method. This is a retrospective study on 34 patients in which resection of prolapsed intervertebral disc was not followed by fusion (10 men and 24 women, C5-C6: n=16, C6-C7: n=18) operated in 2005, and 14 patients in which resection of prolapsed intervertebral disc was followed by cage fusion. There were 10 men and 4 women, C5•C6: n=8, C6-C7: n=6, operated in the first 6 months of 2006. Fusion was performed with Affinity cage filled with autogenously bone derived from the iliac crest. We used only one cage at every procedure, with diameter 1 mm larger than the height of intervertebral space. Results. In the first group, after a follow-up of minimum 1 year we observed a reduction of intervertebral space at the operated level in 18 patients; in 16 cases the intervertebral space disappeared completely (vertebral bloc); surface area of the intervertebral foramen was smaller than preoperatively; 14 patients (40%) complained of residual paresthesia and 6 patients (18%) complained of limited range of motion in axial rotation. In the second group, after minimum 6 months follow-up the intervertebral space remained with the same height in 4 patients and was larger in 10. The intervertebral foramen at the same level had the same surface area as preoperatively. Adjacent intervertebral spaces were in 6 patients reduced by 1 or 2 mm: Patients of this group had neither paresthesia nor other neurological deficits. The cages remained in place with fusion observed on plain radiographs after 3 months. Conclusions: Decompression of the neural root was followed by clinical amelioration; persistence of paresthesia in 40% and limited range of motion in 18% of the first group of patients respectively may be explained by narrowing of the intervertebral foramen and intervertebral space, postoperatively. These drawbacks do not occurred when we performed excision of hemiated intervertebral disc and fusion of the motor segment with cage. Only one cage/level is necessary and sufficiently to obtain good results.
