MASTLIF (Maximum Access Surgery Transforaminal Lumbar Interbody Fusion)

MASTLIF (Minimally Access / Minimally Invasive Transforaminal Lumbar Interbody Fusion) is a modern, muscle-sparing spine surgery used to treat painful lower-back conditions caused by damaged discs or unstable spinal segments.

The procedure is performed through small incisions in the lower back, allowing the surgeon to stabilise the spine and relieve nerve pressure with minimal disruption to surrounding muscles.

MASTLIF may be recommended for patients with:

Chronic lower back pain not responding to non-surgical care

Leg pain, numbness, or weakness caused by nerve compression

Slipped disc (disc herniation)

Degenerative disc disease

Spinal instability or spondylolisthesis

How the procedure works

Small incisions are made at the back of the spine
Muscles are gently separated rather than cut
The damaged disc is removed from one side of the spine
A spacer (cage) is placed between the spinal bones
Screws and rods are inserted through small openings to stabilise the spine
Over time, the bones fuse together, creating long-term stability

Why patients choose MASTLIF

Less muscle damage compared to traditional open surgery
Effective relief of back and leg pain
Smaller incisions and reduced blood loss
Improved spinal stability
Faster mobilisation and recovery for many patients

Safety

MASTLIF is a widely used and well-established minimally invasive technique. When performed by trained spine surgeons, it offers reliable outcomes with a lower impact on surrounding tissues compared to traditional open fusion surgery.

SUMMARY

MASTLIF stabilises the spine and relieves nerve pressure using a minimally invasive approach—supporting recovery with less disruption and lasting support.
