Researchers retrospectively studied data on 51 patients with adult spinal deformity after thoracolumbar fusion from the pelvis to thoracolumbar junction with at least six months of follow-up. Health-related quality of life outcomes, demographics and radiograph parameters of deformity were compared for patients who underwent the following procedures:
• No cement
• Two-level cement augmentation at upper instrumented vertebra and vertebra one level proximal to UIV
• Cement at another location
Here are four key points:
1. A total of 19 patients underwent two-level cement augmentation at UIV, 23 patients had no cement and nine patients underwent cement at another location.
2. Researchers found that two-level procedures without cement had a 19 percent revision rate for proximal junctional fractures compared with a 0 percent revision rate for two-level procedures with cement.
3. When adjusted for UIV, the risk of proximal junction fracture revision surgery increased by 13.1-times for the “other” category of patients.
4. In addition, two-level cement increased HRQoLs in all patients, while only back and leg pain significantly improved in non-two-level cement procedures.
