Sacroiliac Joint Dysfunction is rated by the U.S. Department of Veterans Affairs under DC 5236 of 38 CFR § 4.71a, DC 5236 across 6 severity tiers (10% / 20% / 30% / 40% / 50%…). Service connection requires (1) a current diagnosis, (2) an in-service event, injury, or exposure, and (3) a medical nexus opinion linking the two under 38 C.F.R. § 3.303.
Sacroiliac joint dysfunction is pain and impaired movement arising from the paired sacroiliac joints, where the base of the spine (sacrum) meets the pelvis (ilium), commonly from abnormal joint motion (hypermobility or hypomobility), ligament laxity, or post-traumatic and degenerative change. Veterans typically report deep low-back, buttock, hip, or groin pain that worsens with prolonged standing, climbing stairs, transitions such as rising from sitting, and single-leg load, sometimes with referred pain into the posterior thigh. Diagnosis rests on a cluster of provocation maneuvers (for example FABER/Patrick, thigh thrust, compression, distraction, and Gaenslen tests), often supported by imaging or a diagnostic intra-articular SI joint injection that relieves the pain.
