Camptocormism
Alternate names[edit | edit source]
Camptocormia; Bent spine; Bent Spine Syndrome; Idiopathic camptocormia; Idiopathic camptocormism; Idiopathic progressive lumbar kyphosis
Definition[edit | edit source]
Camptocormia, camptocormism or "bent spine syndrome," (BSS) is an extreme forward flexion of the thoracolumbar spine, which often worsens during standing or walking, but completely resolves when laying down.
Summary[edit | edit source]
The term itself is derived from the Greek "kamptos" (to bend) and "kormos" (trunk) BSS was initially considered, especially in wartime, as a result of a psychogenic disorder. It is now recognized that in it may also be related to a number of musculo-skeletal or neurological disorders.
Cause[edit | edit source]
- It seems that myopathy is the primary cause of camptocormia based on electromyography, magnetic resonance imaging/computed tomography (CT/MRI scans) of paraspinal muscles, and muscle biopsy.
- The majority of BSS of muscular origin is related to a primary idiopathic (with unknwon cause) axial myopathy of late onset, maybe a delayed-onset paraspinal myopathy, appearing in elderly patients.
- Causes of secondary BSS are numerous.
- The main causes are muscular disorders like inflammatory myopathies, muscular dystrophies of late onset, myotonic myopathies, endocrine and metabolic myopathies, and neurological disorders, principally Parkinson’s disease.
Signs and symptoms[edit | edit source]
It is an extreme forward flexion of the thoracolumbar spine, which often worsens during standing or walking, but completely resolves when laying down.
Diagnosis[edit | edit source]
Diagnosis of axial myopathy is based upon CT/MRI scans demonstrating a lot of fatty infiltration of paravertebral muscles.
Management[edit | edit source]
General activity, walking with a cane, physiotherapy, and exercises should be encouraged. Treatment of secondary forms of BSS is dependent upon the cause.
