Treatment of Unstable Distal Clavicular Fractures (Neer 2b): Hook Plate vs Locking Plate

March 14, 2012 updated by: Leisheng Jiang, Shanghai Jiao Tong University School of Medicine
The investigators propose to test the hypotheses that compared with Hook Plate (HP), Locking Plate (LP) reduces the postoperative complications and leads to a better functional recovery after unstable distal clavicle fractures (Neer 2b).

Study Overview

Indicates the current recruitment status or the expanded access status.

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

Controversy exists regarding the optimal treatment for patients with unstable distal clavicular fractures (Neer 2b). The recognized treatment alternatives are Hook plate.Notably, criticisms on this fixation method also appeared and the potential risks of hook migration, loosening, subacromial impingement or rotator cuff injury, and acromial osteolysis were still unsolved. Recently, Herrmann et al.and Largo et al.stabilized the distal clavicle with Locking plate (LP) and these studies offered encouraging support for LP. Because of small sample size (27 patients) and nonrandomization, the convictive power of these researches is not strong enough.

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

14 years to 76 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

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.
Active Comparator: Hook Plate
20 participants will be enrolled in this group.
Device: Hook Plate
All participants will have an open reduction internal fixation. The affected upper limb will be temporarily fixed by a sling after admission. Under necessary test, general anaesthetic and antibiotic prophylaxis, the patients will be placed in a beach-chair position in an orthopaedic theatre. The operated side will be prepped and draped and a transverse incision will be made over the fracture site. The fracture ends will be identified, reduced and fixed with HP. X-ray was applied to check the grade of reduction before the operation is completed. Post-operative care will include early active mobilization managed by a standard physiotherapy rehabilitation regime.

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
the postoperative complications
Time Frame: 12 months
complication that related with surgery or fracture will be defined as any event that necessitated another operative procedure or additional medical treatment
12 months

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
the affected limb function
Time Frame: 3, 6, 9,12 months
the affected limb function measured using the Constant-Murley Score and using the Disabilities of the Arm, Shoulder and Hand (DASH) Score measured at 3, 6,9and 12months post-operatively.
