Detailed Description

Ankle fracture is a common injury with a wide spectrum of mechanism, especially in the elderly population. Surgical treatment of the unstable ankle fracture presents encouraging outcomes. Open reduction with plate osteosynthesis is the gold standard but is sometimes complicated by wound problems. The overall rate of complications after open reduction and internal fixation of ankle fracture varies from 5% to 40%. Wound complication, including superficial and deep ones, was reported as high as 18.8% in a previous meta-analysis, especially in the patients with high-risk factors e.g. elderly, osteoarthritis and diabetic subpopulation.

Newer implants such as locked fibular nail (FN) have been developed with studies showing promising results. The Acumed fibular rod system is such an alternative method which is a metallic implant with length 110mm, 145 mm and 180 mm. The shorter diameter of the nail (ranging from 3.0 mm-3.6 mm) allows surgeons to make an incision as short as 1 cm compared to the 8-cm incision in conventional lateral plate fixation. Also, it shows advantages in mechanical stability for osteoporotic bone with less prominent metalwork. The nail is anchored by a lateral-medial locking screw at the level of the syndesmosis and two anterior-posterior locking screws distally. A 1-cm longitudinal incision will be made over the tip of the lateral malleolus after performing a closed reduction.

The results from previous studies imply that the fibular rod system may give positive outcomes. However, the majority of the relative studies were single-centre series providing a low level of evidence and lacking a comparative group. For example, a case series retrospectively reviewed 105 patients who experienced surgical treatment using the Acumed fibular rod system for ankle fracture and found good functional and radiographic results with minimal complications. Like all other retrospective studies, the follow up was not complete and some radiographic information could not be obtained. Thus a comparative study with a high level of evidence is required to provide more information for surgeons.

To the investigators' best knowledge, no prospective randomized controlled trials have been conducted to investigate the clinical outcomes and radiographic results after surgical treatment using the Acumed fibular rod system in ankle fracture. The objective of the study is to compare the clinical outcomes of locking fibular nail and to results of the open-reduction with plate fixation in ankle fracture management.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

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

No

Genders Eligible for Study

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.
