Biomechanical differences of Coflex-F and pedicle screw fixation combined with TLIF or ALIF–a finite element study

Lumbar interbody fusion is a common procedure for treating lower back pain related to degenerative disc diseases. The Coflex-F is a recently developed interspinous spacer, the makers of which claim that it can provide stabilisation similar to pedicle screw fixation. Therefore, this study compares the biomechanical behaviour of the Coflex-F device and pedicle screw fixation with transforaminal lumbar interbody fusion (TLIF) or anterior lumbar interbody fusion (ALIF) surgeries by using finite element analysis. The results show that the Coflex-F device combined with ALIF surgery can provide stability similar to the pedicle screw fixation combined with TLIF or ALIF surgery. Also, the posterior instrumentations (Coflex-F and pedicle screw fixation) combined with TLIF surgery had lower stability than when combined with ALIF surgery

This surgical technique consists of a percutaneous approach for the treatment of small to medium size hernias of the intervertebral disc by laser energy. The main objective is to reduce the intradiscal pressure in the nucleus pulposus

Laser Disc Surgery can be performed under local anaesthetic as a day case at our centre on the prestigious Harley Street.
