What is it about?

Lumbar spinal stenosis is a common condition in the elderly. We present 5-year clinical and radiographic results from a pilot study of minimally invasive pedicle-lengthening osteotomy, substantial enlargement of the spinal canal and presents favorable clinical results for both disease-specific and non-disease-specific outcome measures.

Why is it important?

Pedicle-lengthening osteotomy is a promising minimally invasive procedure especially in patients with moderate lumbar stenosis and severe comorbidity to avoid more dangerous open and minimally invasive spinal canal decompression techniques


Performing our pilot study as well as writing this manuscript was a great pleasure as it has co-authors with whom I have had long standing collaborations. It is hoped that the completely new approach to the surgical treatment of symptomatic lumbar spinal canal stenosis presented will generate much interest among spinal surgeons and researchers
