Background Kyphoplasty has been demonstrated to be minimally invasive and effective in treating osteoporotic vertebral fracture patients with back pain over the level of the fractured vertebrae. Rare studies have reported on thoracolumbar vertebral fracture patients presenting with distal lumbosacral pain (DLP). Whether kyphoplasty had a favorable therapeutic benefit for these patients remains unclear. Purpose To evaluate the therapeutic efficacy of kyphoplasty in treating osteoporotic thoracolumbar vertebral fracture (OTVF) patients with DLP and assess the clinical significance of focal tenderness to palpation in these patients. Material and Methods Thirty-two OTVF patients who only complained of DLP were treated by kyphoplasty. The vertebral heights, local kyphotic angle, Visual Analogue Scale (VAS), and Oswestry Disability Index (ODI) scores were assessed preoperatively, one day after surgery, and at last follow-up. All patients were evaluated regarding their degree of satisfaction with kyphoplasty. In addition, we compared the therapeutic efficacy of kyphoplasty in patients with and without focal tenderness to palpation. Results All patients successfully underwent kyphoplasty without complications. The vertebral heights, local kyphotic angles, VAS, and ODI scores were all significantly improved after kyphoplasty and maintained at last follow-up in our patients ( P < 0.001). At last follow-up, all patients expressed satisfaction with kyphoplasty. No significant differences in these parameters were detected between patients with and without focal tenderness. Conclusion The possibility of thoracolumbar vertebral fractures in elderly patients complaining of DLP should not be neglected. Kyphoplasty presents a superior benefit in treating OTVF patients with DLP. The absence of focal tenderness does not influence the clinical efficacy in these patients. [ABSTRACT FROM AUTHOR]

Background: The instantaneously recovered stability and strength following vertebral augmentation prevent continuous micro-motion and further collapse of fractured vertebrae. Despite this, during follow-up of our patients, we observed recompression of augmented vertebrae with significant vertebral height loss and aggravation of local kyphotic deformity.Purpose: To identify the risk factors related to recompression and to evaluate the clinical significance of recompression.Material and Methods: One hundred and twenty-one patients who underwent single-level kyphoplasty for osteoporotic vertebral fractures were retrospectively analyzed and classified into the following two groups: group 1 with recompression and group 2 without recompression. Characteristics of patients and fractured vertebrae were compared between the two groups. Univariate and multivariate regression analyses were performed to identify risk factors for recompression. We evaluated the visual analogue scale (VAS) and the Oswestry disability index (ODI) scores in both groups to elucidate the clinical impact.Results: During an average of 20.75 ± 4.43 months of follow-up, 17 augmented vertebrae developed recompression. In the recompression group, vertebral height loss was accompanied by significantly aggravated local kyphotic deformity. The local kyphotic angle differed significantly between the two groups at final follow-up (P = 0.011). However, the VAS and ODI scores were maintained at final follow-up in both groups although the values were slightly higher in group 1. Solid lump distribution pattern (OR = 8.718; P = 0.003) and the degree of vertebral height restoration (OR = 1.260; P < 0.001) were identified as the most important risk factors for recompression.Conclusion: Fractured vertebrae containing solid lump cement and those with more vertebral height restoration are at higher risk of recompression. More attention should be given to these patients considering the aggravated local kyphotic deformity. [ABSTRACT FROM AUTHOR]

Background: Percutaneous vertebroplasty (PVP) and balloon kyphoplasty (BKP) are minimally invasive and effective vertebral augmentation techniques for managing osteoporotic vertebral compression fractures (OVCFs). Recent meta-analyses have compared the incidence of secondary vertebral fractures between patients treated with vertebral augmentation techniques or conservative treatment; however, the inclusions were not thorough and rigorous enough, and the effects of each technique on the incidence of secondary vertebral fractures remain unclear.Purpose: To perform an updated systematic review and meta-analysis of the studies with more rigorous inclusion criteria on the effects of vertebral augmentation techniques and conservative treatment for OVCF on the incidence of secondary vertebral fractures.Material and Methods: PubMed, MEDLINE, EMBASE, SpringerLink, Web of Science, and the Cochrane Library database were searched for relevant original articles comparing the incidence of secondary vertebral fractures between vertebral augmentation techniques and conservative treatment for patients with OVCFs. Randomized controlled trials (RCTs) and prospective non-randomized controlled trials (NRCTs) were identified. The methodological qualities of the studies were evaluated, relevant data were extracted and recorded, and an appropriate meta-analysis was conducted.Results: A total of 13 articles were included. The pooled results from included studies showed no statistically significant differences in the incidence of secondary vertebral fractures between patients treated with vertebral augmentation techniques and conservative treatment. Subgroup analysis comparing different study designs, durations of symptoms, follow-up times, races of patients, and techniques were conducted, and no significant differences in the incidence of secondary fractures were identified (P > 0.05). No obvious publication bias was detected by either Begg's test (P = 0.360 > 0.05) or Egger's test (P = 0.373 > 0.05).Conclusion: Despite current thinking in the field that vertebral augmentation procedures may increase the incidence of secondary fractures, we found no differences in the incidence of secondary fractures between vertebral augmentation techniques and conservative treatment for patients with OVCFs.
