Approach
Anterior abdominal + robotic posterior fixation
Duration
~2 hours 30 minutes
Hospital stay
Typically 1–3 days
Overview
Accesses the disc through the front of the abdomen — minimizing disruption to back muscles and nerves — then secures the segment from behind using a robotic arm to place pedicle screws with sub-millimeter accuracy.
Who it's for
Patients with degenerative disc disease, spondylolisthesis, or a failed previous spinal surgery, most commonly at the L4–L5 and L5–S1 levels.
Why patients choose this approach
- Direct disc access without disrupting back muscles
- Allows excellent restoration of disc height and alignment
- Robotic-guided posterior screw placement for precision
Conditions treated
Degenerative Disc Disease
Degenerative disc disease describes age-related wear of the spinal discs that can lead to chronic neck or back pain and contribute to other spine problems including herniations, stenosis, and instability.
Spondylolisthesis
Spondylolisthesis is a condition in which one vertebra slips forward over the one below it, sometimes producing back pain, leg pain, and instability — though many patients have minimal or no symptoms.
Spinal Stenosis
Spinal stenosis is a narrowing of the spinal canal that compresses the spinal cord or nerve roots, producing leg pain, walking limitation, and — in cervical cases — hand and balance problems.
