【摘要】：目的探討運(yùn)用MRI檢查測量固定節(jié)段鄰近椎間盤髓核容積的變化,來研究ISOBAR TTL動態(tài)內(nèi)固定系統(tǒng)對固定節(jié)段鄰近椎間盤退變的影響。方法回顧分析2010年3月-2011年10月,采用ISOBAR TTL動態(tài)內(nèi)固定系統(tǒng)手術(shù)治療的34例單節(jié)段腰椎間盤突出癥患者臨床資料。男20例,女14例;年齡39~62歲,平均47.5歲。病程6~18個月,平均14個月。病變節(jié)段:L4、5 21例,L5、S1 13例。腰椎間盤突出癥類型:旁中央型23例、外側(cè)型11例。術(shù)前及術(shù)后6、12、18、24、36、48個月常規(guī)行X線片及MRI檢查,采用角平分線法測量固定節(jié)段頭側(cè)鄰近椎間隙高度,MRI輔助髓核容積測定法測量固定節(jié)段頭側(cè)鄰近髓核容積。比較手術(shù)前后鄰近節(jié)段椎間隙高度及髓核容積,評價Isobar TTL動態(tài)內(nèi)固定技術(shù)對固定節(jié)段頭側(cè)鄰近椎間盤退變的影響。結(jié)果術(shù)后30例獲隨訪,均隨訪至48個月。手術(shù)前后各時間點(diǎn)間比較鄰近節(jié)段椎間隙高度差異均無統(tǒng)計學(xué)意(P0.05);術(shù)后6、12、18個月的鄰近節(jié)段髓核容積與術(shù)前比較差異無統(tǒng)計學(xué)意義(P0.05),但術(shù)后24、36、48個月的鄰近節(jié)段髓核容積顯著高于術(shù)前(P0.05)。髓核容積各數(shù)值中,術(shù)后6、12、18個月髓核高度及寬度與術(shù)前比較差異無統(tǒng)計學(xué)意義(P0.05),但術(shù)后24、36、48個月髓核高度較術(shù)前增大,髓核寬度較術(shù)前減少,差異均有統(tǒng)計學(xué)意義(P0.05);術(shù)后18、24、36、48個月髓核前后徑均高于術(shù)前,比較差異有統(tǒng)計學(xué)意義(P0.05)。結(jié)論 ISOBAR TTL動態(tài)內(nèi)固定系統(tǒng)對固定節(jié)段鄰近椎間盤退變有一定預(yù)防或延遲其退變的作用。
[Abstract]:Objective to study the effect of ISOBAR TTL dynamic internal fixation system on the degenerative change of the adjacent intervertebral disc of fixed segment by MRI. Methods from March 2010 to October 2011, the changes of the volume of the nucleus pulposus were measured. The clinical data of 34 patients with single segment lumbar disc herniation treated by ISOBAR TTL dynamic internal fixation system were reported. There were 20 males and 14 females, the age was 3962 years (mean 47.5 years), the course of disease was 6 ~ 18 months. The average of 14 months was 14 months. There were 13 cases of L5N S1 in 521 cases of lesion segment. The types of lumbar disc herniation were: paracentric type in 23 cases, lateral type in 11 cases. X ray and MRI were performed before and after operation in 612 cases and 18 cases in 24 cases before and after operation, 48 months after operation, X ray examination and MRI examination were performed routinely. The height of the proximal intervertebral space of the fixed segment was measured by angular bisection and the volume of the adjacent nucleus pulposus was measured by MRI assisted with the measurement of the volume of the nucleus pulposus adjacent to the fixed segment, the height of the adjacent segment of the vertebral space and the volume of the nucleus pulposus were compared before and after the operation. To evaluate the effect of Isobar TTL dynamic internal fixation on the degenerative changes of the proximal intervertebral disc in the head and side of the fixation segment, 30 patients were followed up. All patients were followed up to 48 months. There was no significant difference in the height of adjacent intervertebral space between each time point before and after operation, and there was no significant difference in the volume of adjacent segments of nucleus pulposus between 612,18 months postoperatively compared with that before operation, but there was no significant difference in the volume of adjacent segments of nucleus pulposus before and after operation, but there was no significant difference in the volume of adjacent segments of nucleus pulposus before and after operation. The volume of adjacent segments of nucleus pulposus was significantly higher than that of preoperatively (P 0.05). There was no significant difference in the height and width of the nucleus pulposus between before and after operation (P 0.05), but the height and width of the nucleus pulposus increased at 2436,48 months after operation, and the width of the nucleus pulposus decreased. The difference was statistically significant (P 0.05), and the anteroposterior diameter of nucleus pulposus was significantly higher than that of preoperation at 18 ~ 24 ~ 36,48 months postoperatively. Conclusion the dynamic internal fixation system of ISOBAR TTL can prevent or delay the degeneration of adjacent intervertebral disc.
