• Compression fracture of the anterior part of vertebral body occurring in forward flexion
• Usually does not produce neurological deficits
• It is a stable fracture as only the anterior column of spine is involved
• Caused by : Road traffic accidents, Fall from height
• Predisposing factors : Osteoporosis

Three column concept of spine stability

According to the three column concept, the spine is considered to have 3 columns:

• Anterior
• Middle
• Posterior

The anterior column is composed of:

• Anterior longitudinal ligament
• Anterior half of vertebral body and intervertebral disc

The middle column is composed of:

• Posterior longitudinal ligament
• Posterior half of vertebral body and intervertebral disc

The posterior column is composed of:

• Transverse process
• Spinous process
• Pedicle
• Lamina
• Faceted joints
• Interspinous ligament
• Supraspinous ligament
• Ligamentum flavum

Spinal injury and Three column concept:

• One column injury is stable
• Two column injury is unstable
• Three column injury is invariably unstable

Swan neck deformity refers to a structural deformity of the hand in which

• proximal interphalangeal joints are in hyperextension
• distal interphalangeal joints are in hyperflexion

• Commonly seen in injuries or inflammatory conditions like rheumatoid arthritis
• Seen in 50% of patients with rheumatoid arthritis
  
• Treatment is by surgical correction
