Abstract
44
Surgery of spinal deformities and vertebral tumors often requires extensive arthrodesis, with the difficulty of obtaining sufficient autogenous bone graft (particulary in children and cases of paralytic deformities) and the necessity of a second incision, thus lengthening the operation and eventual increase of the morbidity.
We present 52 patients who suffered from vertebral tumours, fractures or spinal deformities and underwent spinal arthrodesis surgery. Femoral head allografts were used as cancellous bone graft to add to 207 the amount obtained from the arthrodesis bed itself (posterior structures). In three occassions, femoral head grafts shaped as a strut were also used as intersomatic bone graft, being implanted via a costotansversectomy.
The only complication was the appearance of seromas of spontaneous resorption in the first 15 cases (thereafter repeated cleaning of the bone graft avoided this problem).
In our experience, bone grafts facilitate the carrying out of shorter surgical operations but can also avoid having to recourse the further incisions without reducing the possibility of obtaining a succesful arthrodesis.
