• Spinal instability
• Spondylolisthesis
• Degenerative disc disease
• Degenerative scoliosis
• Revision spine surgery exp. Recurrent disc herniation

• For insert disc spacer/cage for spinal fusion
• Pedicle screw fixation at the back of the lumbar spine
• Can decompression of the spinal canal simultaneously

1. TLIF (Transforaminal lumbar interbody fusion) 

• Midline surgical incision at back
• One surgical wound for insert disc spacer, pedicle screw fixation and decompression of the spinal canal

2. MIS-TLIF (Minimally invasive Transforaminal lumbar inter-body fusion) 

• Minimally invasive technique
• Multiple small incision at back
• Used tubular retractor for spinal canal decompression and insertion of disc spacer
• Percutaneous pedicle screw fixation 

3. OLIF (Oblique lumbar inter-body fusion) 

• Minimally invasive technique
• Approach from the side of the body for insertion of large disc spacer
• Percutaneous pedicle screw fixation from the back 

4. Endo-LIF (Endoscopic assist lumbar interbody fusion) 

• Minimally invasive technique
• Multiple small incision at back
• Used endoscope for spinal canal decompression and assist for insertion of disc spacer
• Percutaneous pedicle screw fixation from the back 

Surgical technique depends on spinal pathology and surgeon experience. Percutaneous pedicle screw fixation can be assisted by O-arm navigator for increase accuracy.
 

• Hospital stay after surgery for 2-4 days
• Wound healing 10-14 days
