This work has been done at orthopedics department, Assiut university hospital Assiut Egypt from January2008 to December 2010.
It was done to assess the effect of use of these cages in multiple levels CSM up to 4 levels through the anterior approach instead of posterior wide decompression for such cases
Fifty five patients were included in this study (age was 37-78 years with mean 55). Forty were males and 15 were females. They were followed up for one year in the average (at least 4 months).
The patients were chosen according to the inclusion criteria: chronic complaint of more than 3 months, with any grade of spasticity with failure of conservative treatment, with radiological and electrical studies preoperatively.
On follow up, the entire patients showed neurological improvement of one grade at least. no deterioration was reported in this study. the fusion was reported in all patients within 3 months in the average no cage extrusion or retropulsion was reported. Superficial wound infection was reported in 2 cases that was relieved by repeated dressings for short time with good wound healing. No tracheal or oseophygeal fistulae were reported
The conclusion that this solution is a very good technique to mange CSM compared with other posterior techniques, with avoidance of complications of using iliac bone graft with no or minimal complications
