病例 女,23歲,因“反復(fù)腰痛并彎腰障礙1個(gè)月”來院。患者1個(gè)月來反復(fù)下腰痛,伴晨僵、彎腰困難,深呼吸時(shí)感胸廓僵硬,休息后不緩解,活動(dòng)后改善,夜間疼痛影響睡眠,翻身及改變體位困難,左側(cè)髖關(guān)節(jié)陣發(fā)疼痛。無強(qiáng)直性脊柱炎(AS)家族史,無心、肺、肝、腎等器質(zhì)性疾病史。查體：腰部僵直,豎棘肌痙攣,腰部前屈、左右側(cè)屈活動(dòng)差,指地距37 cm,擴(kuò)胸度2.8 cm,Schober試驗(yàn)2.9 cm,骶髂關(guān)節(jié)壓痛、叩痛明顯,雙下肢“4”字試驗(yàn)陽性,雙下肢深淺感覺未見異常,各肌肌力可,會(huì)陰部感覺可,生理反射可,病理反射未引出?；颊連oth AS活動(dòng)指數(shù)7.9,Bath AS功能指數(shù)7.4。實(shí)驗(yàn)室檢查：血沉64 mm/h,C反應(yīng)蛋白47 mm/L,人類白細(xì)胞抗原B27(HLA-B27)陽性。骨盆平片、骶髂關(guān)節(jié)CT提示骶髂關(guān)節(jié)間隙模糊變窄,邊緣硬化呈輕度鋸齒樣改變；腰椎MRI提示脊髓圓錐下降至腰4椎體水平,腰骶椎椎管明顯擴(kuò)大,終絲明顯增粗,終絲固定,骶椎椎管內(nèi)脂肪瘤。診斷：強(qiáng)直性脊柱炎合并脊髓栓系綜合征；骶椎椎管內(nèi)脂肪瘤。目前予以柳氮磺胺吡啶+來氟米特藥物治療,并指導(dǎo)患者功能鍛煉。下一步待強(qiáng)直性脊柱炎穩(wěn)定后,擬針對(duì)脊髓栓系綜合征進(jìn)行手術(shù)治療。

討論 AS患者早期累及中軸骨骼以及骶髂關(guān)節(jié),以腰骶部疼痛為主要癥狀[1],目前多數(shù)臨床研究證明,柳氮磺胺吡啶對(duì)早期血沉增快并伴有外周關(guān)節(jié)炎的AS治療有效[2]。而來氟米特對(duì)合并外周關(guān)節(jié)炎的AS治療效果較好,可維護(hù)脊柱功能[3]。在口服藥物治療效果較差或者無效時(shí),可應(yīng)用生物療法,如抗腫瘤壞死因子抗體治療[4],但這些治療都非常昂貴[5]。此外,功能鍛煉對(duì)于AS的治療也起著至關(guān)重要的作用[6]。盡管本例患者左側(cè)髖部疼痛,但髖臼、股骨頭骨質(zhì)尚未見異常,因此尚屬于AS病變?cè)缙?行藥物治療以及功能鍛煉有效。

脊髓栓系綜合征(tethered cord syndrome,TCS)系脊髓圓錐下終絲或馬尾固定于椎管,于脊柱生長(zhǎng)期中,牽拉脊髓圓錐,使之不能向頭側(cè)移動(dòng)而產(chǎn)生脊髓或圓錐牽拉損害癥狀之綜合征。目前認(rèn)為其病理生理學(xué)基礎(chǔ)為終絲牽拉造成脊髓血供減少,代謝紊亂,進(jìn)而造成感覺、運(yùn)動(dòng)神經(jīng)損傷[7]。對(duì)脊髓栓系綜合征建議盡早手術(shù),如等待神經(jīng)癥狀的出現(xiàn)再行手術(shù),則可能出現(xiàn)神經(jīng)不可逆損傷[8]。脊柱后路截骨治療栓系綜合征有效[9]。本例患有強(qiáng)直性脊柱炎,且屬于活動(dòng)期,無明顯栓系綜合征癥狀,因此,暫時(shí)予以控制強(qiáng)直性脊柱炎,待控制后再盡早行栓系綜合征手術(shù)治療。
