Therapeutic Efficacy of Percutaneous Curved Kyphoplasty Compared With Percutaneous Kyphoplasty in Treatment of Osteoporotic Vertebral Compression Fractures.

Background: Osteoporotic vertebral compression fractures (OVCFs) frequently occur in older adults. Appropriate surgical treatment of these fractures is still not well understood. This study sought to evaluate the therapeutic effectiveness of percutaneous curved kyphoplasty (PCKP) compared to percutaneous kyphoplasty (PKP) for OVCFs.

Materials and methods: This study retrospectively analyzed 68 OVCF patients who underwent surgeries from July 2021 to June 2022 in Sheyang County People's Hospital. Patients were categorized into two groups based on surgical procedure (PCKP group = 35 patients, PKP group = 33 patients). Surgery duration, amount of x-ray imaging sessions conducted intraoperatively, bone cement injection dose, and outflow rate were compared between the two groups. Visual analogue scale (VAS), anterior vertebral height (AVH), and Cobb angle were measured at 1 week and 12 months after surgery.

Results: Compared with the PKP group, the amount of intraoperative x-ray imaging sessions (P<0.05) and bone cement outflow rate (P<0.05) were noticeably reduced in the PCKP group. The results identified no variation between groups in cement injection dose (P>0.05). No meaningful statistical variation was found in VAS scores (P>0.05), anterior border height of the injured vertebra (P>0.05), or Cobb angle (P>0.05) between two groups at 1 week and 12 months.

Conclusion: This research suggests both PKP and PCKP are efficient and secure for pain relief, restoring vertebral body height, and correcting the Cobb angle. However, PCKP has advantages in reducing surgery duration, amount of intraoperative x-ray imaging sessions, and bone cement outflow rate. [Orthopedics. 2025;48(4):210-214.].
