My back

Clinical Summary: Chronic Lumbar & Pelvic Dysfunction

Initial Injury:
The first instance of lower back pain occurred after the Hawkesbury Classic—a high-load 111km, 13 hours of endurance canoe race completed without sufficient conditioning. This event likely caused a sacroiliac joint shear or torsional strain, resulting in long-term posterior rotation of the left innominate (left pelvic bone). The mechanical stress, combined with core fatigue and asymmetrical loading, overwhelmed stabilizing musculature and allowed the pelvis to shift and lock into a rotated position.

Current Radiological Findings (09 May 2025):

Pelvic unleveling with left iliac drop

The left hip is forward (anteriorly rotated hemipelvis)

The right hip is back (posteriorly rotated hemipelvis)
10 mm apparent leg length difference (shorter on left)

Left lumbar inclination (spinal curve into the lowered side)

Degenerative changes at L2–L5 (spondylosis, osteophytes, vacuum cleft)

No spondylolisthesis or structural fracture noted

Functional Chain of Dysfunction:

1. Pelvic Rotation (Left Posterior)

Origin: old injury from untrained overuse during the canoe race

Effect: functional leg length discrepancy, core destabilization


2. QL Strain (Left Bias)

Compensatory overuse of QL for pelvic stabilization

Chronic tension contributes to ongoing pain and postural distortion


3. Lumbar Disc Degeneration

Asymmetrical spinal loading over years

Accelerated wear at L2/3–L4/5 from cumulative mechanical shear


4. Rib Dislocations

Secondary to chronic QL tension and thoracolumbar fascial distortion

Indicates full-chain compensation involving thoracic spine

Conclusion:
Ian’s condition is not the result of isolated events, but a chronic adaptation to an old, uncorrected pelvic injury. The body developed long-term neuromuscular compensation patterns to stabilize a rotated pelvis, leading to persistent spinal and thoracic dysfunction. Management requires both mechanical realignment and neuromuscular re-education to reverse years of maladaptive compensation.
