Summary

This study shows that using the Luque rectangle for spinal decompression and fusion significantly improves leg and back pain in patients with degenerative spondylolisthesis. Patients experienced better mobility and high fusion rates with minimal complications.

Area of Science:

  • Orthopedic Surgery
  • Neurosurgery
  • Spinal Fusion

Background:

  • Degenerative spondylolisthesis often causes debilitating spinal stenosis.
  • Surgical intervention, including decompression and fusion, is a common treatment.
  • The Luque rectangle has been explored as a tension band device in spinal fusion.

Purpose of the Study:

  • To evaluate the efficacy and safety of the Luque rectangle for spinal decompression and fusion.
  • To assess patient outcomes, including pain reduction and functional improvement.
  • To determine fusion rates and hardware-related complications.

Main Methods:

  • A cohort of 24 patients with spinal stenosis secondary to degenerative spondylolisthesis underwent decompression and fusion.
  • The Luque rectangle was utilized as a tension band device.

  • Patients were followed up for an average of 21.3 months, with outcomes assessed via pain scores and functional metrics.

    • Main Results:

    • Significant improvements in leg pain (91%) and back pain (90%) were reported.
    • Average walking distance increased substantially from 1.1 to 6.8 blocks.
    • A high fusion rate of 96% was achieved with minimal progression of spondylolisthesis.

    Conclusions:

    • The Luque rectangle serves as a simple and effective tension band device for spinal fusion in degenerative spondylolisthesis.
    • This technique leads to substantial pain relief and functional gains for patients.
    • The procedure demonstrates a low complication rate and high fusion success.
