Psoas Hematoma Presenting as Femoral Neuropathy Following Basivertebral Nerve Ablation: A Case Report

of background data: Sacroiliac joint (SIJ) dysfunction is a common yet frequently underdiagnosed cause of chronic low back pain.Although corticosteroid injections are widely used for SIJ dysfunction, their clinical benefits are often short-lived.Ozone therapy has emerged as a potential alternative, but comparative clinical evidence remains limited.Objectives: This study aimed to compare the clinical effectiveness of ultrasound-guided corticosteroid and ozone injections in patients with chronic low back pain due to sacroiliac joint dysfunction.Methods: This comparative clinical study included 64 patients with chronic SIJ dysfunction who received ultrasound-guided sacroiliac joint injections with either corticosteroid (n=31) or ozone (n=33).Pain intensity was assessed using the Numeric Rating Scale (NRS), disability using the Oswestry Disability Index (ODI), and quality of life using the Short Form-12 Physical (PCS) and Mental (MCS) Component Summary scores.Outcomes were evaluated at baseline, 3 months, and 6 months.Results: Both treatments significantly improved pain, disability, and quality of life at 3 months (all p < 0.001).However, improvements were significantly greater and more durable in the ozone group across all outcomes at both 3 and 6 months.At 6 months, benefits were maintained only in the ozone group, while outcomes in the corticosteroid group returned to near-baseline levels.A ≥50% pain reduction was achieved at 3 months in 97.0% of ozone-treated patients versus 45.2% of corticosteroid-treated patients (p < 0.001) and persisted at 6 months in 18.2% and 0% of patients, respectively (p= 0.013).Discussion/Conclusion: Ultrasound-guided ozone injection provided greater and more durable improvements in pain relief, functional status, and quality of life compared with corticosteroid injection in patients with SIJ dysfunction.Ozone therapy may represent a promising minimally invasive treatment option for the management of chronic SIJ dysfunction-related low back pain.
