Abstract

Purpose: The aim of this study was to report seven cases of metallic radial head prosthesis and present the limit of use in Korea. Materials and Methods: Metallic radial head arthroplasty was performed on 7 patients between April 2006 and December 2006, who had complex elbow injury including comminuted radial head fracture. Indication, operative findings and outcome were assessed. Availability and payment of implant were investigated. Results: All of the patients had more than one associated injury including coronoid fracture, olecranoan fracture, and ligament ruptures. According to Mason classification, there were three type III and four type IV fractures. All radial head fractures were too comminuted to reconstruct. There were two excellent results, four good, and one poor, as graded by Mayo score. There were no patient with instability and implant related complications. Insufficient supply of implant did not enable to do scheduled surgery in 2 cases. Current medical insurance did not cover charge for radial prosthesis, five patients could not help paying for that by themselves. Conclusion: Metallic radial head implants are useful when the radial head cannot be repaired reliably. Preoperative preparing and coverage by medical insurance based on appropriate indication are helpful for decision for a treatment option.

목적: 총 7예의 금속형 요골 골두 치환술을 경험하여 적응증을 바탕으로 국내 요골두 치환술의 실태와 필요성을 소개하고자 하였다. 대상 및 방법: 2006년 4월부터 고려대학교 정형외과 교실에서 경험하였던 총 7예의 환자를 대상으로 수술 적응증, 수술 소견 및 수술 후 상태를 조사하였다. 그리고 치환물의 술 전 준비상태와 보험 적용 여부를 조사하였다. 금속형 치환물은 양극성 유형의 요골두 치환물(Tornier SA. Saint-Ismier, France)을 사용하였다. 결과: 전 예에서 요골두 분쇄 골절 이외에 $1{\sim}2$ 곳의 다른 골절 및 연부조직 손상을 동반한 복합 손상으로 요골두 치환술의 적응증에 해당되었다. 요골두 골절은 Mason 분류상 III형이 3예, IV형이 4예였고 분쇄골절로 인해 만족할만한 내고정을 얻지 못해 치환술을 시행하였다. 술 후 평가에서는 우수 2예, 양호 4예, 불량 1예였고 추시 시 치환물의 문제로 인한 합병증은 보이지 않았다. 술 전 수술 기구의 공급 부족으로 2예에서 수술 날짜를 변경하였고 치환물에 대한 비용은 산재 환자 2예를 제외한 5예에서 환자 개인이 부담하였다. 결론: 요골 골두의 분쇄를 포함한 주관절의 복합 손상에서 금속형 치환물은 술 전 계획 하에 준비되어야 하며, 의료보험의 적용으로 의사 및 환자들의 치료 선택에 도움을 주어야 할 것으로 생각되었다.
