Sacroiliac Joint Dysfunction

Sacroiliac joint dysfunction is pain or reduced movement from one or both joints connecting the spine to the pelvis. These joints transfer load between the upper body and legs. The term may describe irritation, altered movement or pain from nearby tissues; it does not by itself identify one single cause.

Sacroiliac joint dysfunction commonly presents with buttock pain and lower-back pain. Discomfort may stay on one side or be felt across the pelvis, and can worsen with prolonged standing, stairs, turning in bed, running or getting up from a chair. Some people notice tenderness near the dimples at the back of the pelvis, while others feel stiffness rather than sharp pain.

Possible contributors include a sudden increase in activity, uneven loading through the legs, a fall, repetitive lifting, reduced hip or trunk control, and irritation after pregnancy-related changes. Arthritis or inflammation can also affect the joint. Pain may come from more than one structure, so a physical examination is needed before assigning the joint as the source.

Symptoms can fluctuate with activity, posture, sleep and recovery. Some episodes settle with modified movement and rehabilitation; others persist or return when the same load is repeated. A gradual increase in walking, strength and daily activity is usually planned around symptoms rather than a fixed timetable.

Risk may be higher with previous pelvic or lower-back injury, physically demanding work, repeated one-sided movements, prolonged sitting, reduced leg strength or a noticeable difference in leg loading. Pregnancy and recent changes in exercise can alter forces around the pelvis, but pain can occur without any clear risk factor.

A clinician asks where the pain travels, what brings it on and whether symptoms affect walking, sleep or work. They assess spinal, hip and pelvic movement and may use a group of provocation tests. Imaging is not always needed; it may be considered when symptoms are persistent, the examination is unclear or another condition needs investigation.

Care is matched to the examination and your goals. Physiotherapy may use graded strengthening for the hips and trunk, movement retraining, mobility work and advice on pacing. Manual therapy can be used alongside active exercise for short-term symptom relief. If pain remains limiting despite rehabilitation, a clinician may discuss a sacroiliac joint injection as a diagnostic or treatment option.

Break long sitting or standing periods into shorter intervals and change position before pain builds. Keep everyday movement within a tolerable range, use supportive techniques for lifting and follow a home programme consistently. Record activities that flare symptoms and the recovery time so your clinician can adjust the plan.

Seek urgent medical assessment for new loss of bladder or bowel control, numbness around the groin, marked leg weakness, fever with severe back pain, or pain after significant trauma. These features can point to problems beyond the sacroiliac joint and need separate evaluation.

Reduce flare-ups by increasing exercise gradually, training both sides of the body, strengthening the hips and trunk, and using lifting techniques that keep loads close. Address recurring pain early so movement habits and work demands can be reviewed before they become entrenched.

A physiotherapist, sports-medicine clinician, orthopaedic specialist or spine clinician can assess pelvic and lower-back pain. Choose someone who examines the hip, spine and nerves as well as the sacroiliac joint, then explains how the proposed treatment will be measured.
