Sacrum Fracture

Causes, Symptoms, and Treatment of Sacral Fractures

A sacrum fracture is a break in the triangular bone at the base of the spine, just above the tailbone (coccyx). The sacrum connects the spine to the pelvis and plays a key role in supporting body weight and stabilizing the hips. Fractures of the sacrum can occur from high-impact trauma, such as a car accident or fall from a height, or from stress and bone weakness in older adults.

Symptoms of a sacral fracture include lower back or buttock pain, especially when standing, walking, or changing positions. Pain may also radiate into the hips or legs. In some cases, numbness, tingling, or bowel/bladder issues may occur if nearby nerves are affected.

Diagnosis is made through physical examination and imaging such as X-rays, CT scans, or MRI. Sacrum fractures may be classified by zone (e.g., zone I, II, or III) depending on the part of the sacrum involved, and whether the fracture is stable or unstable.

Treatment depends on the severity and stability of the fracture. Stable fractures may be managed with rest, bracing, and activity modification. Unstable fractures or those involving nerve compression may require surgical stabilization.
