Summary
Sarcopenia, the loss of muscle mass, is a significant independent risk factor for osteoporotic vertebral compression refractures (OVCRFs). Advanced age, low bone mineral density, and female sex also increase OVCRF risk.
Area of Science:
- Gerontology
- Orthopedics
- Radiology
Background:
- Osteoporotic vertebral compression refractures (OVCRFs) pose a significant health burden.
- Sarcopenia is increasingly recognized as a factor in various health conditions.
- The relationship between sarcopenia and OVCRFs requires further investigation.
Purpose of the Study:
- To investigate the association between OVCRFs and sarcopenia.
- To identify independent risk factors for OVCRFs.
Main Methods:
- Evaluated 237 patients undergoing percutaneous kyphoplasty (PKP) for OVCF.
- Assessed sarcopenia using computed tomography (CT) for muscle mass and grip strength for muscle strength.
- Analyzed risk factors including age, sex, BMI, BMD, and vertebral characteristics.
Main Results:
- Sarcopenia was present in 20.3% of patients and significantly correlated with advanced age, lower BMI, lower BMD, and hypoalbuminemia.
- Sarcopenic patients exhibited a higher risk of OVCRFs.
- Multivariable analysis identified sarcopenia (OR 2.271), low BMD (OR 1.968), advanced age (OR 2.431), and female sex (OR 4.666) as independent predictors of OVCRFs.
Conclusions:
- Sarcopenia is a novel and independent risk predictor for osteoporotic vertebral compression refractures.
- Low bone mineral density, advanced age, and female sex are also critical risk factors for OVCRFs.

One of the core constructs in social psychology is the notion of an attitude toward an object or person. Traditionally, psychologists measured attitudes by simply asking people to self-report their beliefs, opinions, or feelings. This approach has limitations, however, when measuring socially sensitive attitudes, like racial prejudice, because people are often motivated to self-report unprejudiced, egalitarian beliefs (despite...

01:27Muscles of the Vertebral Column
3.1K
The back muscles that lie deep into the thoracolumbar fascia are called intrinsic or true back muscles. These muscles are divided into four layers: superficial, intermediate, deep, and deepest layers.
Superficial Layer:
The superficial layer consists primarily of the splenius muscles, which include the splenius capitis and splenius cervicis. These muscles are mainly responsible for the head and cervical spine movements, including extension, rotation, and lateral bending. The splenius capitis...

In addition to being held together by the intervertebral discs, adjacent vertebrae also articulate with each other at synovial joints formed between the superior and inferior articular processes called zygapophysial joints (facet joints). These are plane joints that provide for only limited motions between the vertebrae. The orientation of the articular processes at these joints varies in different regions of the vertebral column and serves to determine the types of motions available in each...
