Trial summary

The purpose of this study is to use a novel load monitoring technology to correlate limb loading to OTA type 42IIIB and IIIC tibial fracture outcomes. This study will be the first to collect continuous limb loading data and will provide the first objective insight into how limb loading directs fracture healing. Read more about this study

About this study

Official title: Development and Clinical Trial of an Insole Sensor to Determine Optimal Limb Loading in the Rehabilitation of OTA Type 42IIIB and IIIC Lower Extremity Fractures

The purpose of this study is to use a novel load monitoring technology to correlate limb loading to OTA type 42IIIB and IIIC tibial fracture outcomes. This study will be the first to collect continuous limb loading data and will provide the first objective insight into how limb loading directs fracture healing. To meet this purpose, two specific aims have been developed.

Specific Aim 1: Preclinical validation of a load-monitoring insole

Read more

The Hitchcock laboratory has overcome the greatest technical hurdle for continuous limb load monitoring: development of load sensor technology that is affordable, accurate and capable of monitoring for over four weeks. To develop this sensor technology into a load-monitoring insole, the Hitchcock lab will incorporate consumer type electronics into the design, including a microprocessor, battery, and data storage media.

Following construction of a functional load-monitoring insole, a pilot human study with orthopaedic trauma patients from the University of Utah (N=20) will be conducted to identify modes of device failure, improve device interfacing and develop data handling protocols and software for the clinical arm of the proposed study.

Specific Aim 2: Conduct a prospective, direct observational cohort study.

Thirty (30) open tibial fracture patients will be recruited at two centers: University of Utah (N=15) and William Beaumont Army Medical Center (N=15). Participants will wear a walking boot instrumented with the load-monitoring insole that will continuously record limb loading and serve as a step counter. X-rays collected at standard-of-care follow-up visits will be used by Drs. Kubiak and Orr to subjectively evaluate fracture healing. A questionnaire regarding subjective perception of patient compliance will be collected at the first and last follow-up visits. Data collected from the insole sensor will be correlated to objective measures of fracture healing and subjective measures of patient compliance to determine the effect of patient limb loading on injury outcome. The Hitchcock laboratory will develop software to process and summarize data from the load monitoring insole and continually improve human interfacing factors of the load monitoring insole based off of feedback from the clinical team and study participants.

    Measured: Follow Up Visits up to 1-Year

Secondary outcomes (1)
  1. X-ray (AP and Lateral)

    Subjectively evaluate fracture healing

    Measured: Follow Up Visits up to 1 Year

Questions about this trial

What is this clinical trial studying?

An observational study of Lower Extremity Fractures, run by University of Utah at 1 site in United States.

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 12 inclusion and 14 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 26 Oct 2017. 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 United States. 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?

Patient Activity Measure (PAM-13) Questionnaire (time frame: Follow Up Visits up to 1-Year). 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 26 Oct 2017.
