Spondylolysis
🔎 What is it?�
A stress fracture of the pars interarticularis, usually from repetitive extension + rotation.
🧠 Anatomy refresher:
The pars interarticularis links superior and inferior articular processes.
Fracture disrupts posterior vertebral ring, often at L5.
⚠️ Aetiology (Causes):
Sports requiring extension/rotation: cricket fast bowlers, gymnastics, dance, volleyball.
Rapid adolescent growth + high training load.
Unilateral > bilateral fractures.
📊 Incidence:
3–6% general population.
Up to 30–60% in elite extension-sport athletes.
Most common cause of back pain in young athletes.
💡 Why Physiotherapy Matters:
Early detection + load modification (stop aggravating extension).
Core bracing + lumbar neutral movement training.
Progressive return:
1. Pain control →
2. Stabilisation →
3. Controlled extension →
4. Sport-specific retraining
