Abstract
Purpose: This study aims to determine whether the psoas volume measured from a pelvic computed tomography (CT) could be a potential opportunistic diagnostic tool to measure muscle mass and sarcopenia in patients with hip fractures. Methods: This was a retrospective cohort study. In total; 57 consecutive patients diagnosed with hip fractures who underwent surgery were enrolled. A cross-sectional area of the psoas muscle was measured at the lumbar (L) 3 and L4 vertebrae from a pelvic CT for the diagnosis of hip fractures. The psoas muscle volume was calculated with a three-dimensional modeling software program. The appendicular skeletal muscle mass (ASM) and preoperative handgrip strength (HS) were measured. The correlations between the psoas muscle volume/area and ASM/HS were assessed. Data on patient demographics; postoperative complication; length of hospital stay; and Koval scores were also recorded and analyzed with respect to the psoas muscle area/volume. Results: The psoas muscle volume and adjusted values were significantly correlated with ASM; which showed a stronger correlation than the psoas muscle area did at the L3 or L4 level. HS was correlated with the psoas volume or adjusted values; but not with the cross-sectional area of the psoas muscle. Among the adjusted values; the psoas muscle volume adjusted for the patient’s height (m2) showed a strongest correlation with ASM and HS. The psoas muscle volume was not significantly correlated with postoperative complications or short-term functional outcomes. Conclusions: The psoas muscle volume measured from a pelvic CT for the diagnosis of hip fractures showed a stronger correlation with ASM and HS than the cross-sectional area did. Therefore; the psoas muscle volume could be a potential diagnostic tool to assess the quantity of the skeletal muscle in patients with hip fractures without an additional examination.
Highlights
Sarcopenia is a progressive and generalized skeletal muscle disorder associated with an increased likelihood of adverse outcomes, such as falls, fractures, physical disability, and mortality [1]
According to the Asian Working Group for Sarcopenia (AWGS), sarcopenia is diagnosed when a patient exhibits a combination of a low muscle quantity and either low muscle strength or physical performance, while severe sarcopenia is diagnosed if the patient exhibits a low muscle quantity, low muscle strength, and low physical performance [9]
This study demonstrated that the psoas muscle volume, its adjusted values, and the cross-sectional area at the L3 and L4 level were significantly correlated with appendicular skeletal muscle mass (ASM) and that an adjusted psoas muscle volume showed a higher correlation coefficient than the unadjusted psoas muscle volume and cross-sectional area did
Summary
Sarcopenia is a progressive and generalized skeletal muscle disorder associated with an increased likelihood of adverse outcomes, such as falls, fractures, physical disability, and mortality [1]. In patients with hip fractures, sarcopenia is a significant independent predictor of postoperative clinical outcomes, including mortality, active daily life, mobility, and quality of life [2,3,4,5,6,7,8]. More prompt treatments and active rehabilitation options are needed in patients with hip fractures diagnosed with sarcopenia. According to the AWGS diagnostic criteria, muscle quantity is assessed using the appendicular skeletal muscle mass (ASM), which can be measured through dual-energy. Muscle strength is measured by assessing handgrip strength. In patients with acute hip fractures, J.
