Abstract
INTRODUCTION AND IMPORTANCE: Double level isthmic spondylolisthesis at L3-L4/L4-L5 is exceedingly rare with only a few documented cases in the literature, but to our knowledge no detailed case reports have been written. CASE PRESENTATION: 49 year old male with L3-4, L4-5 isthmic spondylolisthesis with neurologic symptoms and failed conservative management treated with L3-4, L4-5 Gill laminectomy, transforaminal interbody fusion with bone grafting and L3-5 posterior instrumented fusion. CLINICAL DISCUSSION: While rare, this condition can be successfully treated with posterior decompression and instrumented interbody fusion similar to single level spondylolisthesis. Surgeons should feel confident that they can achieve a good outcome for patients and feel comfortable offering this procedure. CONCLUSION: This case report may offer guidance for surgeons in the future as it explores the successful treatment of double level isthmic spondylolisthesis at L3-L4/L4-5 from initial presentation to final post-operative follow-up where the patient had complete resolution of symptoms.
