  • Ages 15 to 60 years
  • All sexes
  • Healthy volunteers accepted
  • Child, Adult

Who may be able to join

  • a soft-tissue defect in the areas where sensory return was considered important ●a defect with exposed bone or tendon in one finger

About this study

Sensory coverage in the finger continues to be a challenging problem. This study reports sensory reconstruction of the fingers with the bilaterally innervated dorsal digital flaps and compares the results between the dual- and single-innervated flaps.The main evaluated outcomes are static 2-point discrimination and Semmes-Weinstein monofilament scores of the flap, fingertip pain and joint motion.

Read the detailed description

Pain was given subjectively by the patient using the visual analogue scale (VAS). The VAS consists of a 10 cm line that was grouped into mild (0-3 cm), moderate (4-6 cm) and severe (7-10 cm). Tinel's sign was rated as the following: grade 1=none; grade 2=mild, slight tingle; grade 3=moderate, very uncomfortable; and grade 4=severe, patient unable to use hand because of any stimulation of the neuroma.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Flap including bilateral nerve branchesProcedure or surgery

    Two nerve branches are attached with the flap for sensory coverage

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Static 2PD test

    We use a Disk-Criminator to test two nearby points when touching the flap

    Measured: 18 months to 24 months after surgery

Questions about this trial

What is this clinical trial studying?

A study testing Flap including bilateral nerve branches in people with Soft Tissue Injuries, run by The Second Hospital of Tangshan at 1 site in China.

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 4 inclusion and 4 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: finished, as of the sponsor's last update on 29 Oct 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Static 2PD test (time frame: 18 months to 24 months after surgery). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02167646, which also lists 2 linked publications.

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 29 Oct 2018; AzTrials last refreshed its copy on 8 Nov 2026.
