BACKGROUND: Sacroiliac joint (SIJ) pain is a prevalent cause of chronic low back pain (LBP), affecting many adults in the United States. The SIJ provides stability and proper weight distribution from the trunk. Degenerative disruption to this joint can result in shearing and tension that can lead to significant pain and force imbalances. Previous treatment often failed to provide complete and long-term pain relief.

CASE REPORT: This article follows a 72-year-old woman with a medical history of chronic right-sided LBP. The patient received a corticosteroid injection, a T10-S1 fusion, conventional therapies, such as physical, nonsteroidal anti-inflammatory drugs, and tizanidine without sustained relief. Patient reported complete relief after the LinQ procedure (PainTEQ, Tampa, FL).

CONCLUSIONS: This case report highlights the emerging evidence on the sustained safety and efficacy of a salvage posterior SIJ fusion technique using the LinQ device (PainTEQ, Tampa, FL) in a patient with persistent back pain, following multiple unsuccessful treatments.
