Performance of Double-Arm Digital Subtraction Angiography (DSA)-Guided and C-Arm-Guided Percutaneous Kyphoplasty (PKP) to Treat Senile Osteoporotic Vertebral Compression Fractures

New Insights in the Pathophysiology, Epidemiology, and Response to Treatment of Osteoporotic Vertebral Fractures

CONTEXT

Vertebral fractures (VFs) make up an important but challenging group of fractures often caused by osteoporosis. Osteoporotic fractures pose unique diagnostic challenges in generally requiring imaging for diagnosis. The objective of this narrative mini-review is to provide an overview of these recent advances in our knowledge of VF pathophysiology and epidemiology with particular focus on endocrine diseases, prevention, and treatment.

EVIDENCE ACQUISITION

We searched PubMed on May 23, 2022, for studies of VFs in humans. Results were limited to papers available as full-text publications in English, published from 2020 and onward. This yielded 3457 citations. This was supplemented by earlier publications selected to add context to the recent findings.

EVIDENCE SYNTHESIS

Studies addressed VF risk in hyperthyreosis, hyperparathyroidism, acromegaly, Cushing syndrome, primary aldosteronism, and diabetes. For pharmaceutical treatment, new studies or analyses were identified for romosozumab and for weekly teriparatide. Several studies, including studies in the immediate pipeline, were intervention studies with vertebroplasty or kyphoplasty, including combination with stem cells or pharmaceuticals.

CONCLUSIONS

Endocrinologists should be aware of the high likelihood of osteoporotic VFs in patients with endocrine diseases. Though licensed treatments are able to substantially reduce the occurrence of VFs in patients with osteoporosis, the vast majority of recent or ongoing randomized controlled trials in the VF area focus on advanced invasive therapy of the fracture itself.

Digital Subtraction Angiography-Guided Percutaneous Kyphoplasty in Treatment of Multi-Segmental Osteoporotic Vertebral Compression Fracture: A retrospective single-Center study

Purpose

This study aimed to explore the effectiveness and safety of digital subtractionangiography (DSA)-guided percutaneous kyphoplasty (PKP) in treating multi-segmental osteoporotic vertebral compression fracture (OVCF).

Methods

We retrospectively reviewed 68 patients with multi-segmental OVCF who had unilateral PKP surgeries using DSA and C arm guiding at our hospital between October 2016 and June 2020 and were followed for at least two years. All patients were divided into two groups: DSA guidance (n = 31) and C-arm guidance (n=37). In addition, we collected the clinical and radiological evaluation results during postoperative and last follow-up periods.

Results

Our findings revealed that the DSA guidance group required lesser time for channel establishment and surgery than the C-arm guidance group at P < 0.05. The incidences of bone cement leakage, fluoroscopy times, and radiation dose of the DSA guidance group were significantly lesser than the C-arm guidance group (P < 0.05). Compared to the C-arm guidance group, the deviation of puncture in the DSA guidance group was significantly lower, the puncture angle in the DSA guidance group was significantly larger, and better bone cement distribution was obtained (P < 0.05). Compared to preoperative data, the VAS score, median vertebral height, and Cobb angle were significantly improved one day after surgery and the final follow-up in both groups (P < 0.05). However, the VAS score, the median vertebral height, average length of stay, and Cobb angle were not significantly different between the two groups (P > 0.05).

Conclusion

DSA-guided PKP in treating multi-segmental OVCF can shorten the operation time, improve puncture accuracy, reduce the times and dose of fluoroscopy, reduce the leakage of bone cement, and achieve better cement distribution.
