Idiopathic camptocormia

Idiopathic camptocormia, also known as idiopathic bent spine syndrome, is a rare postural disorder characterized by an abnormal, involuntary forward flexion of the thoracolumbar spine that appears during standing or walking and disappears in the supine (lying down) position. The term 'camptocormia' derives from the Greek words 'kamptos' (to bend) and 'kormos' (trunk). In the idiopathic form, no identifiable underlying neurological, muscular, or skeletal cause can be found, distinguishing it from secondary camptocormia which may occur in the context of Parkinson's disease, myopathies, dystonia, or other conditions. The condition primarily affects the musculoskeletal system, specifically the paraspinal (back extensor) muscles. Patients typically present with a forward trunk flexion of 45 degrees or more that worsens with prolonged standing or walking and is fully reducible when lying flat or when the patient leans against a wall. This abnormal posture can lead to significant functional impairment, back pain, fatigue, difficulty with balance, and reduced quality of life. Some patients may also experience difficulty breathing due to the compressed thoracic cavity. Imaging of the paraspinal muscles may reveal fatty infiltration and atrophy, though the cause of these changes remains unclear in the idiopathic form. Treatment of idiopathic camptocormia is largely supportive and symptomatic. Physical therapy and rehabilitation programs focusing on strengthening the trunk extensor muscles and improving posture are considered first-line approaches. Orthotic devices such as thoracolumbar braces or corsets may provide temporary relief. In refractory cases, spinal surgery with instrumented fusion has been attempted, though outcomes are variable and complications can occur. There is no established pharmacological treatment specifically for the idiopathic form, and the condition tends to be chronic and progressive in many patients.
