Abstract
BackgroundHere we compared the clinical efficacy of bilateral percutaneous kyphoplasty (PKP) and percutaneous curved kyphoplasty (PCKP) in the treatment of osteoporotic vertebral compression fractures (OVCF).MethodsSeventy-two patients with single-level thoracolumbar OVCF were randomly divided into 2 groups (36 patients in each) and were subjected to either PCKP or bilateral PKP. The intraoperative fluoroscopy time, total surgical time, bone cement injection volume, bone cement leakage, preoperative and postoperative anterior vertebral height, Cobb angles, visual analog scales (VAS) and oswestry disability index questionnaire (ODI) were recorded.ResultsBoth groups of patients had a trend towards improvements in VAS and ODI scores 24 h and 6 months after surgery, when compared to preoperative results, despite lack of statistical significance. The total surgical and intraoperative fluoroscopy times and intraoperative bone cement injection volume were significantly decreased in the PCKP group than those in the PKP group. The anterior edge height and Cobb angle of the injured vertebra were similarly improved after operation in both groups.ConclusionPCKP is safer, less invasive and quicker than traditional bilateral PKP despite similar short-term effects for the treatment of OVCF.Trial registrationChiCTR, ChiCTR2100042859.

Highlights
We compared the clinical efficacy of bilateral percutaneous kyphoplasty (PKP) and percutaneous curved kyphoplasty (PCKP) in the treatment of osteoporotic vertebral compression fractures (OVCF)
The bilateral transpedicular approach has disadvantages, such as a long operation time, need of several punctures and a large amount of radiation, which can lead to the “binocular” phenomenon that occurs when the bone cement injected from both sides do not fuse [3]
We have focused our research on achieving a uniform distribution of bone cement in the vertebral body through a unilateral approach
Summary
We compared the clinical efficacy of bilateral percutaneous kyphoplasty (PKP) and percutaneous curved kyphoplasty (PCKP) in the treatment of osteoporotic vertebral compression fractures (OVCF). The loss of bone height and vertebral body compression fractures lead to kyphotic deformities in the vertebral spine of patients, causing long-term back pain and seriously affecting their quality of life. The commonly used puncture approaches include a unilateral straight approach and a bilateral transpedicular approach, both of which can improve the back pain of patients [3, 5]. The bilateral transpedicular approach has disadvantages, such as a long operation time, need of several punctures and a large amount of radiation, which can lead to the “binocular” phenomenon that occurs when the bone cement injected from both sides do not fuse [3]. The introduction of percutaneous curved kyphoplasty (PCKP) provided a new approach for the treatment of OVCF [6]
