Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Consecutive patients presenting with trigger finger interested in surgical release of the A1 pulley will be prospectively treated with endoscopic versus open surgical release of the A1 pulley. Study measures will include scar assessment based on the Patient and Observer Scar Assessment Scale (POSAS) administered at 1 week, 1 month, and 6 months post-operatively, overall satisfaction (scale of 1 to 10), days before return to work, duration of post-operative occupational therapy, pain medication use, operative time, and complication and recurrence rates.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

  • Have realistic expectations of surgical results
  • Be willing to undergo surgical or endoscopic treatment
  • Understand and be willing to follow all aspects of the study protocol and have signed and dated the Informed Consent Form and the Authorization for Use and Release of Health and Research Study Information (HIPAA) form prior to any study-related procedures being performed

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Endoscopic Release
12 patients recommended for surgical treatment of trigger finger will undergo endoscopic release.
Device: Endoscopic Release
Retrograde endoscopic release of the A1 pulley for treatment of trigger finger will be performed using a commercially available device by A.M. Surgical, Inc. This device has been cleared for marketing, sale and use by the U.S. Food and Drug Administration (FDA) for use as an Orthopedic manual surgical instrument based on its similarity in structure and function to previously used devices.
Active Comparator: Standard Open Release
12 patients recommended for surgical treatment of trigger finger will undergo standard open surgical release.
Procedure: Standard Open Release
Standard open surgical release of the A1 pulley for treatment of trigger finger.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Scar Comparison Between Treatment Arms, as Measured by the Patient and Observer Scar Assessment Scale (POSAS)
Time Frame: 1 Week, 1 Month and 6 Months after surgery
Questionnaires, completed by both the patient and the patient's surgeon/Physician Assistant (PA-C), contain 6 items on a 10-point scale (1 is best, 10 is worst). Scores range from 12 to 120 with 12 indicating normal skin and 120 indicating worst scar imaginable.
1 Week, 1 Month and 6 Months after surgery

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Overall Patient Satisfaction: 10 Point Scale
Time Frame: End of Study (6 months after treatment)
The patient's overall satisfaction after surgery based on a 10 point scale with 1 indicating no satisfaction and 10 indicating extremely satisfied.
End of Study (6 months after treatment)
Weeks Before Return to Work
Time Frame: End of study (6 months after treatment)
Number of weeks after surgery before patient returns to work
End of study (6 months after treatment)
Duration of Post-operative Therapy
Time Frame: End of study (6 months after treatment)
Number of days after surgery the patient participates in occupational therapy
End of study (6 months after treatment)
Pain Medication Use
Time Frame: End of Study (6 months after treatment)
Number of days opiates used after surgery
End of Study (6 months after treatment)
Number of Complications
Time Frame: Through study completion, an average 1 year
Injury to tendons, nerves, or digital vessels, surgical site dehiscence or surgical site infections requiring antibiotics
Through study completion, an average 1 year
Rate of Recurrence
Time Frame: At any time point after treatment; through study completion, an average 1 year
Triggering of treated finger, confirmed on physical exam by treating physician, requiring re-operation
At any time point after treatment; through study completion, an average 1 year
