Clinical Efficacy Study of Magnesium-Containing Degradable Polymer Bone Repair Material for Bone-Defect Repair After Extremity Bone Tumor Resection

Sponsor: Yu Zhang, PhD

Summary

This is a single-center prospective randomized open-label non-inferiority clinical trial for adult patients with bone defects after extremity bone tumor resection. This study aims to evaluate the analgesic effect, osteogenic capacity and safety of magnesium-containing degradable polymer bone repair material. Up to 72 eligible patients aged 18-75 years will be enrolled and randomly divided into two groups at a 1:1 ratio. Patients in the experimental group will receive magnesium-containing degradable polymer bone repair material to fill bone defects after tumor removal. Patients in the control group will be implanted with conventional magnesium-free bone repair material. All participants will receive unified surgical anti-infection treatment, pain control, wound management and postoperative rehabilitation.The main study goal is to test whether the pain-relieving effect of the magnesium-containing material is not worse than conventional bone repair material. We will calculate total opioid pain-killer medicine consumption within 3 days, 7 days and 1 month after surgery. Secondary observations include newly-formed bone volume measured by CT three-dimensional reconstruction, surgical site infection rate and local tumor recurrence rate. Patients will complete scheduled follow-up visits at 1-month, 3-month and 6-month after surgery. All unexpected health problems or adverse reactions will be recorded during follow-up.
