Quantification of Multifidus Atrophy and Fatty Infiltration Following a Minimally Invasive Microdiscectomy

Abstract

BackgroundMultifidus muscle degeneration and atrophy have been demonstrated following traditional open spine surgery. The purpose of this study was to quantify multifidus muscle atrophy and fatty infiltration following a 1-level minimally invasive (MIS) lumbar discectomy.

Magnetic resonance spectroscopic analysis of multifidus muscles lipid content and association with spinopelvic malalignment in chronic low back pain

“…Second, we positioned the VOI and measured IMCLs and EMCLs once only at the L4 through L5 level because pathological change appears most often at that location based on previous reports. 10,46,47 At this level, the paraspinal muscle is the main muscle protecting the spinal structure controlling the gliding motion in all lumbar vertebrae. 48,49 Intra-and interobserver reliabilities studies indicated that the inherent error of the IMCLs measurement is about 6%.…”

Evaluation of intramyocellular and extramyocellular lipids in the paraspinal muscle in patients with chronic low back pain using MR spectroscopy: preliminary results

“…1,21,39 At this level, the paraspinal muscle is thought to be the main muscle protecting the spinal structure controlling the gliding motion at each articuli intervertebrales. 40,41 Previous studies 23,42 have reported that atrophy and fat infiltration of the Mm appear to occur at multiple levels and are side specific in relation to symptoms in patients with CLBP and that degenerative scoliosis is associated with the asymmetry of paraspinal muscle changes.…”

“…2). В послеоперационном периоде контролировали основные параметры: клинические (уровень болевого синдрома в поясничном отделе и нижних конечностях оценивали по визуально-аналоговой шкале (ВАШ), функциональное состояние по ODI, степень удовлетворенности пациента проведенной операцией -по шкале Macnab) при выписке и в отдаленном послеоперационном периоде; инструментальные (формирование костного блока в отдаленном послеоперационном периоде по функциональной спондилографии и МСКТ оценивали рентгенолог и независимый нейрохирург, полноценным спондилодез считали при наличии костных мостиков и сегментарного объема движений менее 3° [16]); степень атрофии многораздельной мышцы оценивали по изменению ее площади на аксиальной МРТ-грамме до и после операции [17]).…”
