[Lower back pain due to sacroiliac joint dysfunction].

Sacroiliac joint (SIJ) dysfunction is an underrecognized yet frequent cause of low back pain, often misdiagnosed due to symptom overlap with other spinal disorders and the absence of clear anatomical abnormalities. This article outlines the diagnostic challenges, clinical presentation, and treatment options for SIJ dysfunction. Risk groups include postpartum women and patients with connective tissue disorders. Diagnosis relies on clinical history, provocation tests, and diagnostic SIJ infiltration with local anesthetics. Initial treatment is conservative, focusing on physical therapy and rehabilitation. For refractory cases, minimally invasive SIJ fusion may be considered, although evidence remains limited. A multidisciplinary approach involving care providers, general practitioners, medical specialists, and paramedical professionals is essential for timely diagnosis and effective care. Increased awareness and structured protocols can reduce unnecessary diagnostics and improve outcomes for patients with persistent low back pain due to SIJ dysfunction.
