Lumbar Discectomy Techniques

Disectomy Technique for Posterolateral L4/5 disc 

 

Anatomy

 

L4/5 disc at level of facet joints

 

Interlaminar space is below disc

- have to take inferior aspect of superior lamina

Prospective multi-centred RCT

- 309 displaced intra-articular fractures

- operative v non operative management

- 2 year follow up
