Oblique lumbar interbody fusion at L5S1(OLIF51)

Acta Neurochirurgica (2019) 161:1079–1083

OLIF51 retains the advantages of traditional ALIF procedure with good fusion rates and improvement in radiographic parameters and reduces its drawbacks. It has the added advantage of being a minimal access technique.

Methods Preoperative analysis of the vascular anatomy using CT angiography is mandatory. OLIF51 is done in right lateral position using specialized retractor blades and Thompson retractor system. The procedure is similar to OLIF at other levels except for the differences described here. The instruments are specialized for OLIF at L5S1.

Conclusion OLIF51 provides an excellent alternative to traditional ALIF

Biportal endoscopic spinal surgery (BESS) for treatment of lumbar spinal stenosis

Biportal endoscopic spinal surgery (BESS) for treatment of lumbar spinal stenosis

Acta Neurochir (2016) 158:459–463

Prevalent endoscopic spine surgeries have shown limitations especially in spinal stenosis. Biportal endoscopic surgery is introduced to manage central and foraminal stenosis with its wide range of access angle and clear view.

Methods The authors provide an introduction of this technique followed by a description of the surgical anatomy with discussion on its indications and advantages. In particular, tricks to avoid complications are also presented.

Conclusions Effective circumferential and focal decompression were achieved in most cases without damage to the spinal structural integrity with preservation of muscular and ligamentous attachments. The biportal endoscopic spinal surgery (BESS) may be safely used as an alternative minimally invasive procedure for lumbar spinal stenosis.
