Failure of Conservatively Managed Traumatic Vertebral Compression Fractures: A Systematic Review.

Background: Most vertebral compression fractures (VCFs) are successfully managed conservatively; however, some patients fail conservative management and require further surgical treatment. We sought to identify significant variables that contribute to progressive vertebral collapse in nonoperative treatment of traumatic VCFs.

Methods: A systematic review identified original research articles of conservatively managed VCFs secondary to trauma from inception to September 2021. Articles with patients treated with initial nonoperative therapy, AO type A0, A1, and A2 fractures, risk factor analysis, >10 patients, and vertebral fracture secondary to trauma were included. Articles with pediatric patients, burst fractures or AO type A3 and A4 fractures, vertebral fractures secondary to neoplasm or infectious disease, and operative versus nonoperative treatment comparations were excluded. Failure of nonoperative treatment was defined as salvage surgery/vertebral augmentation, progressive kyphosis, chronic pain, or functional disability.

Results: Of 3877 articles identified, 6 articles were included with 582 patients with conservatively managed thoracolumbar VCFs. Treatment failure was reported in 102 (17.5%) patients. Of 102 treatment failures, 37 (36.3%) were due to subsequent VCF, 33 (32.4%) were due to back pain or functional disability at follow-up, and 32 (31.4%) were due to increased compression rate or kyphotic deformity at follow-up. Prior VCF was a significant variable in 2 (33.3%) of 6 studies. Age, lumbar bone mineral density, segmental Cobb angle, and vertebral height loss were each described as a significant factor in 1 (16.7%) of the 6 studies.

Conclusions: Identifying patients who are at risk for treatment failure may help select patients who would benefit from close clinical follow-up or early surgical/procedural intervention.
