Two level cervical corpectomy with iliac crest fusion and rigid plate fixation: a retrospective study with a three-year follow-up.

AIM
There is no clear knowlegde in the literature about two-level vertebral corpectomy using the iliac bone crest for fusion and rigid plate fixation. We present our experience with two-vertebral level cervical corpectomy and reconstruction.


MATERIAL AND METHODS
Each patient was graded according to the Nuricks Grade (1972) and the modified Japanese Orthopaedic Association (mJOA) Scale (1991), and the recovery rates were calculated. All patients had two-level vertabral corpectomy. Anterior iliac crest bone graft with titanium plate fixation was applied to all patients.


RESULTS
Postoperatively the mJOA score raised up to 15.5. Mean recovery rate was 69%. Average 25.2 degrees correction of kyphosis was achieved in 21 patients. Among the postoperative complications, three cases (12%) had temporary C5 nerve palsy that was resolved in three weeks, two cases had (8 %) graft malposition and infection, and three cases (%12) had temporary donor site pain.


CONCLUSION
Excellent fusion rates can be achieved following two-level corpectomy with iliac bone graft repacement. This techique is easy, cost effective and safe. If the bone graft is harvested from the iliac crest by standart approach and between anatomical landmarks, most patients do not experience persistent pain at the donor site.
