Abstract

Purpose: The purpose of this study is to observe unicameral bone cyst (UBC) outcome after the fracture has healed and if there is any identifiable prognostic factors. Materials and Methods: 13 UBC patients with pathologic fracture from 2001 to 2010 were reviewed. The mean follow up were 26 months (3-90 months). There were 11 male and 2 female patients and the mean age of the patients were 10.2 years old (6-16 years). 9 involved proximal humerusand 2 involved humerus shaft and 1 involved proximal femur and 1 involved proximal tibia. The treatment of UBC fracture was conservative cast application to heal the fracture initially, and 1 patient was treated with primary auto bone graft and open reduction with internal fixation. 5 patients were treated with steroid injection during follow up period and 2 patients with auto bone graft. We analyzed the change of UBC during pathologic fracture healing period and prognostic factor about age, the size of UBC, the involvement of physis. Results: The mean duration of the fracture healing was 8.2 months. Complete healing were occurred at 4 patients (31%). No statiscal difference was checked with age about UBC healing (p=0.42). But, more larger size about UBC and more closer to physis, the healing was difficult (p=0.05, p=0.03). Conclusion: While pathologic fracture of UBC was possibly healed, active treatment should be applied especially those cysts that involvescloser area of the physis or large size.

목적: 단순 골낭종의 병적 골절 환자를 대상으로 단순 골낭종의 관해에 미치는 예후 인자에 대하여 알아보고자 하였다. 대상 및 방법: 2001년부터 2010년까지 본원에 내원한 단순 골낭종을 동반한 병적 골절 환자 13명을 대상으로 하였으며, 평균 추시 기간은 26개월(3-90개월)이었다. 성별은 남자 11명, 여자 2명이었으며, 평균 나이는 10.2세(6-16세)였다. 발생 부위는 근위 상완골 9명, 상완골 간부 2명, 근위 대퇴골 1명, 근위 경골 1명이었다. 단순 골낭종의 병적 골절에 대하여 보존적 치료로 단순 석고 고정 후 골절 유합을 시도하였으며, 1명은 일차적으로 골이식 및 관헐적 정복술과 내고정술을 시행하였다. 5명의 환자에서 치료 경과 중 스테로이드 주사를 시행하였으며, 2명에서 골이식을 시행하였다. 병적 골절 치료 중의 단순 골낭종의 변화 및 연령, 낭종의 크기, 성장판 침범 정도에 따른 단순 골낭종의 예후 인자에 대해 분석하였다. 결과: 병적 골절 후 전례에서 평균 8.2개월에 골유합을 얻었으며, 13명의 환자 중 4명(31%)에서 골낭종의 완전 관해를 보였다. 발병 나이에 따른 단순 골낭종 관해의 통계적 차이는 없었지만(p=0.42), 낭종의 크기가 클수록, 성장판에 근접한 경우 관해를 얻기가 어려웠다(p=0.05, p=0.03). 결론: 단순 골낭종의 병적 골절에서 관해가 이루어질 수 있으나, 낭종의 크기가 크거나 성장판에 근접한 경우에는 좀 더 적극적인 치료가 필요할 것으로 보인다.
