Abstract
PURPOSE: This study aimed to describe a case of a patient with a lumbar ligamentum flavum cyst combined with spinal instability who underwent cyst resection and transforaminal lumbar interbody fusion (TLIF). METHODS: We present a rare case of a patient with a lumbar ligamentum flavum cyst combined with spinal instability causing radiculopathy. The patient underwent cyst resection and transforaminal lumbar interbody fusion. RESULTS: The patient underwent follow-up for 3 years postoperatively and remained asymptomatic, with favorable radiographic results. CONCLUSIONS: Cysts resection and TLIF for ligamentum flavum cysts combined with spinal instability can achieve sufficient and effective decompression while simultaneously restoring spinal stability. Therefore, this approach is both an effective and safe treatment option.
