About this study
Official title: A Multi-center Study on Mid-term Effect Observation of Biodegradable Conduit Small Gap Tublization Repairing Peripheral Nerve Injury
To observe the Mid-term clinical effect of biodegradable conduit small gap tublization to repair peripheral nerve injury in multi-center．
Read the detailed description
In the study，150 cases of fresh peripheral nerve injury in the upper extremities are recruited in multi-center． After formally informed and obtaining the consent，the biodegradable conduit small gap tublization are used to repair the nerve．Their nerve functional recovery conditions are clinically observed according to the standard score methods provided by SHEN Ning-jiang and British Medical Research Council at 3 years after surgery．The excellent and good rates of the overall nerve functional recovery are calculated．

Questions about this trial
What is this clinical trial studying?
An observational study of Peripheral Nerve Injuries, run by Peking University People's Hospital.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 2 Dec 2017. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Peixun Zhang, MD (0118613611237628, zhangpeixun@126.comb), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Nerve function 1 (time frame: 3 years after surgery). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Dec 2017; AzTrials last refreshed its copy on 6 Nov 2026.
