Evaluation of the role of vertebral augmentation in chronic vertebral compression fractures: A retrospective study.

Objectives: Vertebral augmentation is recommended for acute or subacute vertebral compression fractures (VCFs); few studies claim its usefulness in chronic VCFs also. Use of radionuclide imaging may improvise identification of chronic VCFs that may benefit from vertebral augmentation; hence we have evaluated efficacy of vertebral augmentation procedures in chronic VCFs with incomplete fracture healing suggested either by MRI or Tc99m- MDP bone scan.

Materials And Methods: Patients with chronic osteoporotic VCFs (>12 weeks) during the period of June 2013 to June 2019 were included in this retrospective study; patients with evidence of incomplete fracture healing either by MRI or bone scan imaging with Tc 99m-MDP underwent vertebroplasty or kyphoplasty. Primary outcome measure was patient's pain score measured by numerical rating scale (NRS); secondary outcome measures were patient's disability assessed by Roland Morris Disability questionnaire (RDQ); quality of life assessed by Quality of life questionnaire of European Foundation of Osteoporosis (QUALLEFO) and analgesic usage. P ​< ​0.050 was considered as significant.

Results: 34 patients were enrolled for the study with median fracture age of 36 months. The median NRS pain scores, RDQ scores, QUALEFFO scores and analgesic usage were significantly reduced at all-time points as compared to the baseline value over the follow up period of 1 year after vertebral augmentation procedure (P ​< ​0.050). Cement leakage was seen in 5 patients (15%).

Conclusion: Vertebral augmentation procedures provided significant improvements in pain scores, disability and quality of life in patients of chronic osteoporotic VCFs with median fracture age of 36 months.
