After the fusion is completely healed, the screws . Patients with fusion surgery were considered to get better stability than those without fusion; hence, screws in fused spine might share lower strain and have higher torque. Methods: Theater records from a single spinal surgeon's practice were reviewed to identify patients that had undergone lumbar fusion for discogenic back pain with subsequent pedicle screw instrumentation removal (Expedium, DePuy Synthes) in the preceding 3 years with a minimum of 18 months follow-up.
