Association of Sagittal Balance and Multifidus Fatty Degeneration

Öz

We investigated the relationship between multifidus fatty degeneration (MFFI) and spinopelvic parameters in patients with low back pain (LBP). The study included a total of 244 patients (172 females and 72 males). Spinopelvic parameters were measured using lateral standing x-rays, and L4-5 and L5-S1 levels of multifidus muscle fatty degeneration were graded using axial T2W MRI slices. Patients were divided into three groups based on degeneration grade, and the statistical significance of differences in spinopelvic parameters between the groups was examined. The mean age in the group was 46.9±12.2 years. There was a significant positive correlation between MFFI and age and gender (p<0.001). Pelvic Incidence (PI), Pelvic Tilt (PT), and Sacral Table Angle (STA) were not associated with MFFI. A statistically significant weak negative correlation was found between Lumbar Lordosis (LL), Sacral Slope (SS), and MFFI (p<0.001). Although a weak negative correlation was observed between MFFI and the dynamic sagittal spinopelvic parameters SS and LL, no correlation was observed between MFFI and the compensatory parameter PT. Additionally, there is no correlation between the MFFI and the fixed spinopelvic parameters PI and STA.

Sagital Denge ile Multifidus Kas Dejenerasyonu Arası İlişki

Bu çalışmada alt bel ağrılı hastalarda multifidus yağ dejenerasyonu (MFYD) ile spinopelvik parametreler arasındaki ilişki araştırıldı. Çalışmaya toplam 244 hasta (172 kadın ve 72 erkek) dahil edildi. Gruptaki ortalama yaş 46.9±12.2 idi. Spinopelvik parametreler ayakta lateral lumbar grafi kullanılarak ölçüldü. L4-5 ve L5-S1 seviyelerinde MFYD aksiyel T2W MRG kesitleri kullanılarak derecelendirildi. Hastalar dejenerasyon derecesine göre üç gruba ayrıldı ve gruplar arasında spinopelvik parametreler yönünden istatistiksel anlamlı fark olup olmadığı incelendi. MFYD ile yaş ve cinsiyet arasında anlamlı pozitif korelasyon vardı (p<0.001). Pelvik İnsidans (PI), Pelvik Tilt (PT) ve Sakral Tabla Açısı (STA) ile MFYD arasında ilişki saptanmadı. Lomber Lordoz (LL), Sakral Slop (SS)ve MFYD arasında istatistiksel olarak anlamlı zayıf negatif korelasyon bulundu (p<0.001). MFYD ile dinamik sagittal spinopelvik parametreler olan SS ve LL arasında zayıf bir negatif korelasyon gözlenmesine rağmen, MFYD ile kompansatuar parametre PT arasında herhangi bir korelasyon gözlenmemiştir. Ek olarak, MFYD ile sabit spinopelvik parametreler olan PI ve STA arasında korelasyon bulunmadı.
