About this study

Official title: Effects of Hip Distraction Without a Perineal Post on Venous Blood Flow and Peripheral Nerve Conduction During Hip Arthroscopic Procedures Clinical Protocol: Prospective Study

The purpose of this pilot study is to evaluate the effects of hip distraction without a perineal post on the lower extremity during hip arthroscopic procedures by peri-operative monitoring of various prognostic markers for venous, nerve and tissue injury.

Read the detailed description

The purpose of this pilot study is to evaluate the effects of hip distraction without a perineal post on the lower extremity during hip arthroscopic procedures by peri-operative monitoring of various prognostic markers for venous, nerve and tissue injury. The data from this exploratory study can be used to help develop estimates of the proportions of patients who experience significant venous/nerve/tissue compromise in the lower extremity as a result of the application of traction forces necessary to achieve hip joint distraction, and may serve as a basis for sample size planning in future studies comparing the effects of various methods of hip distraction techniques during hip arthroscopy.

  • Hip Arthroscopy ProcedureProcedure or surgery

    The purpose of this pilot study is to evaluate the effects of hip distraction without a perineal post on the lower extremity during hip arthroscopic procedures by peri-operative monitoring of various prognostic markers for venous, nerve and tissue injury.

What is being measured

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

  1. Intra-operative application of hip distraction without a perineal post to the lower extremity during hip arthroscopy procedures.

    Routine intra-operative application of hip distraction without a perineal post to the lower extremity during hip arthroscopy procedures will result in significant blood flow alterations as measured by Doppler ultrasonography.

    Measured: 12 Days

Secondary outcomes (3)
  1. Pre- and post-operative screening for DVT.

    Pre- and post-operative screening for Deep Vein Thrombosis (DVT) using the D-Dimer assay test is correlative with intra-operative venous blood flow measurements.

    Measured: 12 Days

  2. Estimate the amount of tissue/muscle damage associated with hip arthroscopy procedures.

    To quantitatively estimate the amount of tissue/muscle damage associated with hip arthroscopy procedures using creatine phosphokinase (CPK-MM) serum levels as a prognostic marker.

    Measured: 12 Days

  3. Blood Flow Alterations

    To determine whether routine intra-operative application of hip distraction without a perineal post to the lower extremity during hip arthroscopy procedures results in significant blood flow alterations as measured by significant changes in peripheral nerve conduction as measured by Somatosensory Evoked Potentials (SSEP).

    Measured: 12 Days

The record says: finished, as of the sponsor's last update on 1 Aug 2019. 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?

Intra-operative application of hip distraction without a perineal post to the lower extremity during hip arthroscopy procedures. (time frame: 12 Days). 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 NCT03417934, which also lists 22 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 1 Aug 2019.
