Brief review
전방경유 요추 유합술과 추간공경유 요추 유합술을 비교하여 술 후의 추간공의 높이와 디스크의 각도, 요추전만각 및 시상면 정렬 등의 항목을 측정하여 연구한 논문 입니다.
전방경유 요추 유합술이 추간공경유 요추 유합술에 비해 위에서 언급한 추간공의 높이와 디스크의 각도, 요추전만각 및 시상면 정렬 등의 항목에서 우수한 결과를 보였습니다.
이 논문은 방사선학적 측정값이 주를 이루므로 설명보다는 표로 보는게 쉬워서 아래와 같이 첨부했습니다.

Backgroud of
data
-A primary consideration of all spinal fusion procedures
is restoration of normal anatomy, including disc height, lumbar lordosis,
foraminal decompression, and sagittal balance.
-There has been no direct comparison of anterior lumbar
interbody fusion (ALIF) with transforaminal lumbar interbody fusion (TLIF)
concerning their capacity to alter those parameters.
OBJECT
The authors conducted a retrospective radiographic
analysis directly comparing ALIF with TLIF in their capacity to alter foraminal
height, local disc angle, and lumbar lordosis.
METHODS
▶Study design : retrospective study(medical records and
radiographs review)
▶Subjects: 32 patients (ALIF)+ 25 patients (TLIF)
(2000~2004)
▶Data measurement
-Clinical data: VAS score (pre&post:6,12,24mon)
-radiographic data: foraminal height, local disc angle,
and lumbar lordosis (pre&post)
▶Statistical analyses: included mean values, 95%
confidence intervals, and intraobserver/interobserver reliability for the
measurements that were performed.
RESULTS
-ALIF is superior to TLIF in its capacity to restore
foraminal height, local disc angle, and lumbar lordosis.
▶increasing
rate or degree in radiographic data
-foraminal height: 18.5%(ALIF) vs 0.4%(TLIF)
-local disc angle: 8.3 degrees(ALIF) vs 0.1 degree(TLIF)
-lumbar lordosis: 6.2 degrees(ALIF) vs 2.1 degrees(TLIF)
CONCLUSIONS
-The ALIF procedure is superior to TLIF in its capacity to restore foraminal height, local disc angle, and lumbar lordosis.
