The sacrum-ilium joint plays a essential role in transferring forces between the upper and lower body. Located where the sacrum meets the ilium on each side of the lower back, this joint links the spinal column to the pelvic girdle. While it remains largely stable during routine movement, it dissipates impact forces from the torso to the lower limbs. When this joint develops abnormal mechanics, it can lead to ongoing lumbar discomfort that often resembles symptoms of disc herniation or nerve root compression.
Pain from the pelvic joint typically appears unilaterally in the lower back or gluteal region and may travel toward the groin or knee. It often becomes more severe during weight-bearing activities or posture changes. Some people report unsteadiness or "giving way" around the hips. Because the symptoms are indistinguishable from common back conditions, 小倉南区 整体 it is frequently misdiagnosed. A careful physical exam and sometimes imaging or diagnostic injections are needed to accurately identify the origin.
Several factors can contribute to sacroiliac joint dysfunction. Hormonal changes during gestation are a major contributor due to hormonal changes that loosen ligaments to prepare the pelvis for childbirth. Trauma such as a fall or car accident can also injure the joint. Repetitive stress combined with unilateral muscle weakness or limb inequality can place chronic uneven pressure on the sacroiliac articulation. In some cases, degenerative joint disease or inflammatory spondyloarthropathies affects the joint.
Treatment focuses on restoring normal movement and reducing inflammation. Manual rehabilitation typically initiates care, with targeted drills to enhance gluteal, core, and hip stabilizer strength. Hands-on interventions including manipulation, thrust or non-thrust techniques may help improve joint glide and reduce stiffness. heat applications, and sacroiliac belts can provide symptom reduction. In more severe or persistent cases, injections into the joint or minimally invasive procedures may be considered.
Preventing SI joint discomfort involves maintaining good posture, staying active, and avoiding prolonged sitting or standing in one position. Targeted drills for transverse abdominis, multifidus, and gluteus medius are critically beneficial. If you have recurring low back pain that doesn’t respond to typical treatments, it’s advisable to evaluate for SI joint dysfunction. A comprehensive assessment by a specialist trained in pelvic biomechanics can lead to an targeted intervention and meaningful improvement.
