In a compression calcaneal injury, which type of accompanying injury is often observed?

• A. Ankle sprain
• B. Thoraco-lumbar injury
• C. Fibular fracture
• D. Heel spur

Answer: (B)

In a compression calcaneal injury, the accompanying injury that is often observed is a thoraco-lumbar injury. This type of injury is commonly associated with high-energy impacts, such as falls from a height, which can result in both calcaneal fractures at the foot and vertebral compression fractures in the thoraco-lumbar region. The mechanisms of injury can involve complex forces that impact both the lower extremities and the spine simultaneously.

Compression of the calcaneus indicates a powerful axial load transmitted through the body, which not only affects the foot but also may result in critical injuries along the spinal column, particularly in the thoraco-lumbar region, where the vertebrae can fail under similar compressive forces. Thus, it is essential to assess for spinal injuries in patients with a suspected calcaneal fracture, acknowledging the potential for coexistent thoraco-lumbar injuries due to the nature of the force applied during the incident.
