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

Abstract

ObjectivesVertebral 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 MethodsPatients 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. Results34 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%). ConclusionVertebral 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.
