NCT ID: NCT06269354 Recruiting - Bone Defects Clinical Trials

Multi-center Study on Comprehensive Diagnosis and Treatment of Lower Limb Bone Defect Based on Three-dimensional Printing Technology

Start date: November 1, 2023
Phase:
Study type: Observational [Patient Registry]

The clinical diagnosis and treatment of lower limb bone defect is a difficult problem in orthopedics. The traditional treatment has the shortcomings of long treatment period, no weight bearing in the early stage of the limb, weak mechanical strength, many complications, and difficulty in repairing deformed and large segment bone defects around the joint. The Orthopedics Department of Peking University Third Hospital, the lead unit of this study, developed the TCBridge system based on three-dimensional (3D) printing technology in the early stage, which is the first approved 3D printing lower limb long bone defect repair system in China. The system can achieve personalized and accurate repair of lower limb bone defects, and ensure patients to carry out limb weight and functional exercise safely in the early stage after surgery. On this basis, this study will establish a multi-center clinical case cohort to achieve accurate comprehensive diagnosis and treatment of lower limb bone defects, benefiting patients and contributing to society.

NCT ID: NCT04645186 Recruiting - Bone Defects Clinical Trials

Calcium Phosphate Cement as Bone Void Filler

Start date: January 5, 2020
Phase:
Study type: Observational

This is an observational, prospective, non-randomised, post market clinical follow-up study to compile clinical data on performance and safety of the synthetic bone graft substitute and to assess that the performance and safety of the device are maintained until the reaching of its intended use in a commercial clinical setting in long bone and extremity defects.
