April 25, 2019 e-Pearl of the Week: Camptocormia (Bent spine syndrome)
Camptocormia (Bent spine syndrome)
Camptocormia presents as an abnormal flexion of thoracolumbar spine when standing. Flexion worsens while mobilizing, and wanes when supine.1 Etiology is primarily idiopathic paravertebral muscle degradation. Secondary etiology includes Parkinson’s disease, dystonia, myotonic dystrophy, and medications (olanzapine and valproate).2 The MRI aids in diagnosis with STIR imaging detecting acute edema and T1-weighted imaging demonstrating chronic fatty muscle degredation.3 Multimodal management focuses on analgesics, physiotherapy, and symptom improvement by addressing the underlying pathology or withdrawing medication. Self-perpetuating cycle progressively worsens muscle weakness and arthritic degeneration.2
