Simple Explanation

This study evaluates the effectiveness of using a modified orthopedic robot in percutaneous kyphoplasty (PKP) for single-segment osteoporotic vertebral compression fractures (OVCF). The robot's tracer fixation method was improved by using an adhesive fixation to the skin surface. Patients were divided into a robot group (PKP with the modified robot) and a C-arm group (PKP with C-arm X-ray fluoroscopy). The study compared clinical and imaging outcomes between the two groups. The study found that the robot-assisted approach reduced intraoperative pain, shortened the working channel establishment time, and improved patient satisfaction. It also showed advantages in reducing puncture deviation and improving bone cement diffusion.

Study Duration

10-14 months

Participants

155 patients with single-segment OVCF

Evidence Level

Not specified

Key Findings

1
The robot group had a significantly shorter working channel establishment time compared to the C-arm group (P<0.001).
2
The robot group experienced significantly less intraoperative pain (VAS score) compared to the C-arm group (P<0.05).
3
The robot group showed significantly better puncture accuracy and bone cement diffusion one day after the surgery (P<0.05).

Research Summary

This study aimed to assess the efficacy of a modified orthopedic robot-assisted percutaneous kyphoplasty (PKP) for treating single-segment osteoporotic vertebral compression fractures (OVCF). The study compared robot-assisted PKP to traditional C-arm X-ray fluoroscopy-guided PKP, focusing on clinical and radiological outcomes. The findings suggest that robot-assisted PKP can reduce intraoperative pain, shorten procedure time, improve accuracy, and enhance bone cement distribution compared to the traditional method.

Practical Implications

Improved Patient Comfort

The modified robot-assisted PKP can significantly reduce intraoperative pain for patients undergoing OVCF treatment.

Enhanced Surgical Precision

The robotic system improves the accuracy of puncture and bone cement diffusion, potentially leading to better outcomes.

Reduced Procedure Time

The robot-assisted approach can shorten the working channel establishment time, streamlining the surgical process.

Study Limitations

1
The robot group had a higher dose of intraoperative fluoroscopy compared to the C-arm group.
2
The study has a relatively short follow-up period (10-14 months).
3
The study is a retrospective analysis.
