(b) Grade or I or II spondylolisthesis.
Acute low back pain due to
(a)Compression fracture without neurological
deficit
(b)Tuberculosis of the spine

7. CONTRAINDICATIONS
• Severe lumbar canal stenosis,
• Severe osteoporosis and
• Spinal infection
• Grade III and IV spondylolisthesis

8. KEY FEATURES
• Minimally invasive posterior stabilization
• Minimal dissection and retraction
• No muscles stripping but muscles dilation
• Complete preservation of posterior elements
• Less blood loss
• Less post op pain
• Less scars
• Hospital stay reduced
• Back to normal activities quicker

37. • Distractive reduction maneuver of
ligamentotaxis are performed
• Locking screws previously loaded screw
extender chambers are tightened over the rod

50. ADVANTAGES
• Less disruption to para-spinal muscles and
ligaments
• Decreased post-op pain
• More rapid post-op mobilization
• Shorter length of hospitalization
• Shorter post-op recovery time
