국소 자가골을 이용한 경추 전방 유합술 = 5년 추시 결과

국문 초록 (Abstract)

목적: 유합 충전물로서 국소 자가골의 유용성을 알아보고자 하였다.
대상 및 방법: 2006년 6월에서 2009년 9월까지 퇴행성 경추 추간판 탈출증 환자 중 전방 추간판 제거술과 polyetheretherketone 케이지와 국소 자가골편을 이용한 유합술 후 5년 이상 추시한 환자 21명을 대상으로 연구를 실시하였다.
결과: Visual analogue scale 경부통/방사통 점수는 술 전 5.8/7.7점에서 술 후 1년 1.6/2.3점, 술 후 5년 1.8/2.7점이었다. Neck disability index는 술 전 34.3점에서 술 후 1년 6.25점, 술 후 5년 6.51점이었다. 평균 6.4개월에 전 예에서 골유합을 얻었으며, 추체 간격은 1년 추시 평균 6.31 mm, 5년 추시 평균 6.22 mm로 감소하였고, 케이지 종판 내 함몰은 1년 추시 평균 1.28 mm, 5년 추시 평균 1.31 mm 간격 소실을 보였다. 3 mm 이상의 케이지 종판 내 함몰은 1년 추시 1예, 5년 추시 2예에서 나타났다. 수술 후 합병증으로 나사못의 파손이 1예, 나사못 인장이 1예에서 발생하였고, 전 예에서 술 후 감염은 발생하지 않았다.
결론: 유합 충전물로 국소 자가골을 이용하는 것은 장기간의 추시에도 우수한 골유합 및 임상 증상의 호전을 나타내어 효과적인 방법이라고 생각된다.

Purpose: The purpose of this study is to determine the usefulness of locally harvested autobone as a filling material for fusion.
Materials and Methods: Retrospective study was conducted for 21 patients diagnosed as cervical disc herniation with cervical myelopathy or radiculopathy who underwent anterior cervical fusion using locally harvested autobone and polyetheretherketone solis cage from June 2006 to September 2009, with a follow-up period of longer than 5 years. Radiologic outcomes were evaluated by the rate of bone union, the change of intervertebral height, and the subsidence of the cage.
Results: In clinical results, visual analogue scale score was 5.8±0.71/7.7±0.78 at preoperative, 1.6±0.58/2.3±0.97 at 1-year follow-up, 1.8±0.81/2.7±1.28 at 5-year follow-up, and neck disability index score was 34.3±6.2 in preoperative stage, 6.25±3.21 at 1-year follow-up, and 6.51±4.05 at 5-year follow-up. Radiologically intervertebral height was reduced from average 6.31±0.93 mm in 1-year follow-up to average 6.22±0.85 mm in 5-year follow-up. Subsidence of cage was average 1.28±0.41 mm at 1-year follow-up and average 1.31±0.43 mm at 5-year follow-up, with no statistically significant difference (p＞0.05). Average subsidence of cage in these cases was 3.25 mm. In postoperative complication, screw breakage occurred in 1 case, screw pull out occurred in 1 case, and there was no postoperative infection.
Conclusion: Using locally harvested autobone as filling material for fusion resulted in outstanding bone union and improvement of clinical results. In long term follow-up, there was no significant difference in union rate and complication incidence. Therefore use of locally harvested autobone as a filling material for fusion is considered an effective method.
