Pars Fracture & Spondylolysis

Repetitive loading can create a stress reaction or fracture in the pars interarticularis — the bony bridge linking the front and back of a vertebra.

Symptoms

Activity-related low-back pain is common, especially with extension, rotation, running, or jumping. Some patients have no symptoms, while a slip can occasionally contribute to nerve irritation.

Diagnosis

Standing X-rays assess alignment and any vertebral slip. MRI can show an early stress reaction, while CT defines a mature fracture or bony healing. The hip and other sources of back pain are also examined.

Treatment options

Activity modification, core and hip rehabilitation, and gradual return to sport are central. Bracing is used selectively, and bone health or training mechanics may need attention.

When surgery is considered

Surgery is uncommon and considered when pain remains disabling despite a complete rehabilitation program, the defect is unstable, or an associated slip and nerve compression require treatment.

When to seek care promptly

Seek prompt evaluation if low-back pain is accompanied by radiating leg pain, numbness, or weakness, which can signal an associated slip with nerve involvement.
