Use of autogenous bone graft in orthopaedic practice is common, and various method have been tried to improve the compilcation of the donor site of the bone graft. The authors have experienced that the donor site pain of the autogenous bone graft
is
more severe and prolonged than main operation site pain. We have used a method to fill bone cement into the donor site in order to relieve donor site pain, then observed the nature of the pain and complication.
The study was done to the patients that spinal fusion was performed with autogenous bone graft which extracted from iliac tuberosity in the period from May 1992 to February 1993. Clinical assessment of these cases was made according to the degree
and
duration of the pain on 20 cases which were extracted bone from both iliac tuberosity, and one side was filled with bone cement and the other side were not, and then compared the degree of the pain for each case.
The degree of the pain was classified with subjective pain at resting and walking, and the change of the pain after postoperative 2 weeks, 6 weeks, 3 months, 6 months, 12 months.
1. The group without using bone cement: pain persisted at resting and walking before 3 months, but only for walking after 3 months postoperatively.
2. The group with using bone cement : donor site pain was negligible during resting phase, but some pain during walking.
3. The group with using bone cement: Pain was not developed over 75% of patients after postoperative 3 moths.
The group without using bone cement: Pain was not developed 25% of patients at postoperative 3 months.
4. The difference of overall degree of pain was significant until postoperative 6 weeks (P<0.05), and showed statistically difference until postoperative 3 months (P<0.01), but there was no difference of pain between both donor site was not
observed on
pain after postoperative 6 months.
5. Average bleeding was 13.7 cc for the group for whom bone cement was used, and 47.2 cc for the group for whom bone cement was not used.
