Iliolumbar Ligament Sprain
An iliolumbar ligament sprain occurs when the ligament connecting the pelvis to the lower spine becomes overstretched or injured. This ligament helps stabilise the lower back and pelvis, so when it is strained, it can cause pain in the lower back and upper buttock area. Physiotherapy is an effective treatment that helps reduce pain, restore mobility, and strengthen the surrounding muscles to support recovery.
What is an Iliolumbar Ligament Sprain?
The iliolumbar ligament is a strong band of connective tissue that links the pelvis (ilium) to the lowest vertebra of the lumbar spine. It plays an important role in stabilising the lower back and supporting normal spinal movement.
An iliolumbar ligament sprain occurs when this ligament is overstretched or partially torn. This injury can cause pain and stiffness in the lower back and may limit movement.
Without proper treatment, the surrounding muscles may tighten or spasm in response to the injury.
Causes
An iliolumbar ligament sprain usually occurs when the lower back is exposed to sudden or excessive strain.
Common causes include:
- Heavy lifting with poor technique
- Sudden twisting movements of the lower back
- Forceful bending or arching of the spine
- Sports-related movements involving rotation
- Repetitive strain on the lower back
- Awkward postures during physical activity
These movements can place excessive tension on the ligament and lead to injury.
Symptoms
Symptoms of an iliolumbar ligament sprain often affect the lower back and upper buttock region.
Common symptoms include:
- Pain in the lower back, often on one side of the spine
- Pain in the upper buttock area
- Tenderness over the injured ligament
- Pain when pressing on the affected area
- Muscle tightness or spasms in the lower back
- Pain that worsens with bending, twisting, or arching the back
- Discomfort when sitting or standing for long periods
- Pain that may radiate into the hip or groin
These symptoms can limit normal daily activities and movement.
What Should I Do?
If you suspect an iliolumbar ligament sprain, it is important to seek professional assessment from a physiotherapist.
Early physiotherapy can help:
- Confirm the diagnosis
- Reduce pain and inflammation
- Prevent worsening of the injury
- Promote faster recovery
Avoid activities that increase pain until you receive proper treatment.
Physiotherapy Treatment
Physiotherapy plays a crucial role in the recovery from an iliolumbar ligament sprain.
At ACE Physio Sports, physiotherapists perform a comprehensive assessment before developing a personalised treatment plan.
Treatment may include:
Rest and Activity Modification
Guidance on reducing movements that place strain on the lower back.
Ice Therapy
Ice may be applied during the early stages to reduce pain and inflammation.
Gentle Stretching
Stretching exercises help maintain flexibility without overstressing the ligament.
Strengthening Exercises
Core, lower back, and hip strengthening exercises improve spinal stability and support healing.
Postural Training
Education on proper posture helps reduce strain on the lower back during daily activities.
Manual Therapy
Soft tissue techniques and joint mobilisation help reduce muscle tension and improve movement.
These treatments help restore mobility and prevent future lower back injuries.
What Shouldn’t I Do?
If you have an iliolumbar ligament sprain, certain activities may worsen the injury.
Avoid:
- Ignoring persistent lower back pain
- Continuing heavy lifting or strenuous activities
- Sudden twisting or bending movements
- Prolonged sitting in poor posture
- Delaying physiotherapy treatment
Following professional advice helps prevent complications and speeds up recovery.
Long-Term Effects or Recovery
With appropriate physiotherapy treatment, most iliolumbar ligament sprains heal within a few weeks.
Physiotherapy helps:
- Reduce pain and inflammation
- Restore normal spinal movement
- Strengthen supporting muscles
- Prevent recurrence of lower back injuries

Frequently Asked Questions
Do I need surgery for a Iliolumbar Ligament Sprain?
Most ligament injuries — including partial tears — heal well with physiotherapy alone. Surgery is usually reserved for complete ruptures in high-demand athletes or cases where conservative treatment fails. A physiotherapy assessment can determine the severity and guide the right approach.
My lower back feels very unstable after the injury — is that normal?
Yes — a feeling of instability or "giving way" is common after a ligament injury because the damaged ligament can no longer provide full joint support. Physiotherapy rebuilds stability through targeted strengthening and proprioception (balance awareness) training.
How long until I can return to sport after a Iliolumbar Ligament Sprain?
Timelines depend on severity: mild sprains may resolve in 2–4 weeks, while complete tears requiring surgery can take 6–12 months. Your physiotherapist will use functional tests and strength assessments to confirm you're truly ready before clearing you for full activity.
