NCT05266638

Brief Summary

This retrospective study is to determine whether age is a risk factor for postoperative complications in patients undergoing transforaminal lumbar interbody fusion; specifically whether the risk (odds) of implant failure and the need for revision surgery increases with age.

Outcome Measures

Primary Outcomes (2)

  • Number of Implant failure

    Number of Implant failure (screw loosening, cage subsidence, adjacent level alteration/ degeneration, spondylolisthesis degree, kyphosis of the adjacent intervertebral disc space, reduced height of intervertebral disc space) in relationship to age

    one time assessment at baseline

  • Number of patients needing revision surgery

    Number of patients needing revision surgery, in relationship to age

    one time assessment at baseline

Interventions

Collection of medical data and medical images (MRI, radiographs) of the lumbar spine and pelvis of patients having received TLIF with degenerative spinal diseases from the years 2015-2020 and statistical analysis of the coded data.

Study Population

All patients who received TLIF at the age of 55 years or older at the University Hospital Basel between 01.01.2015 and 1.07.2020.

You may qualify if:

  • Indications for TLIF surgery (e.g., degenerative disc disease, spondylolisthesis)
  • Existing preoperative upright standing sagittal plane X-ray of lumbar spine with clear visibility of pelvis, sacrum and femoral head
  • Existing preoperative MRI of the lumbar region with clear visibility of different fatty infiltration grade and stenosis degree
  • Complete follow-up at 3 months and 1 year postoperatively, including clinical and radiographic data

You may not qualify if:

  • Neuromuscular diseases such as Parkinson's disease or multiple sclerosis according to our records
  • Preoperative infection and/or malignancy tumor with involvement of the bony or soft tissue structures of the lumbar spine
  • Presence of a documented consent dissent
