Evidence Checklist: Sacroiliac Joint Dysfunction

Orthopedic evaluation with sacroiliac joint provocation testsCritical

Examination documenting positive SI joint provocation tests (FABER, FADIR, Gaenslen's, distraction/compression tests, thigh thrust), pain location (over SI joint/buttock), and spinal range of motion.

Nexus opinion linking sacroiliac joint dysfunction to service ("at least as likely as not")Critical

A medical opinion connecting your SI joint dysfunction to military service, including load-carrying activities, parachute landings, vehicle accidents, or chronic postural stress.

SI joint diagnostic injection results

Documentation of a fluoroscopy- or ultrasound-guided SI joint injection with 75% or greater pain relief, confirming the SI joint as the pain generator.

Imaging studies (X-ray, CT, or MRI of sacroiliac joints)

Radiographs or cross-sectional imaging showing SI joint sclerosis, erosions, or arthritic changes. MRI can show active sacroiliitis (edema/enhancement) or structural damage.

Treatment records (physical therapy, SI belt, injections, ablation)

Records documenting sacroiliac belt use, stabilization physical therapy, corticosteroid injections, radiofrequency ablation, or SI joint fusion.

Buddy statement from spouse, family, or fellow service member

A written statement from someone who can describe observable symptoms and how your condition affects daily life.

Personal statement describing symptoms and functional impact

Your own written account of how this condition affects your daily activities, work, and relationships. Describe your worst days.

Completed DBQ Back (Thoracolumbar Spine) ConditionsCritical

Standardized form capturing lumbosacral range of motion, SI joint findings, and functional limitations. VA rates SI joint dysfunction under the spine schedule.

Service treatment records (STRs)Critical

Military medical records showing in-service treatment, complaints, or injuries related to this condition.
