仙腸関節ブロックや骨盤ベルトなどの保存療法の効果が持続せず,日常生活や就労に著しい障害のある仙腸関節性疼痛例に対して仙腸関節前方固定術を行った.男6例,女9例の15例で,年齢は平均49歳(30~86歳),罹病期間は平均3.9年(1~7年),術後経過期間は平均2.3年(6カ月~5年)であった.片側前方固定術を14例に,両側固定術(骨盤輪固定術)を1例に施行した.これらの症例について,関節癒合をCTで,また臨床症状をJOAスコア,VASによる疼痛の変化,Roland-Morris disability questionnaire(RDQ)で評価した.関節癒合は15例全例で得られていた.JOAスコアが術前平均5.6点(4~9点)から術後平均18点(7~24点)に,VASが84(70~93)から40(10~75)に,RDQ得点が21.1(17~23)から6.9(1~14)に改善した.仙腸関節前方固定術の成績は良好であり,保存療法に抵抗する症例には有効な治療法と考えられる.
