Abstract:
OBJECTIVETo observe the effectiveness and safety of allograft in posterior spinal fusion in patients with scoliosis.
METHODS41 cases of 54 scoliosis patients with allograft for spinal fusion were followed up. The mean follow-up time is 16 months. Foreign body reaction was studied clinically and fusion status was assessed radiographically.
RESULTSThere was no foreign body reaction significantly in all patients. Acute deep wound infection happened in one patient and no chronic deep wound infection occurred. There was no disease transferred by allograft in followed patients. New bone formation appeared after 4 months postoperatively in radiogram. At final follow-up, the mean angle of 3.4 degrees lost and minimal -1 degrees and maximal 6 degrees . Implants were fastened and did not loosen and fracture.
CONCLUSIONSAllograft for posterior spinal fusion in scoliosis patients was useful and safe.
