Trial summary

The purpose of the research is to determine if there is a difference between two of the commonly used less invasive techniques (surgical methods that use a smaller incision or cut in the skin) used to perform total hip arthroplasty (replacement of your painful hip with a new ball and socket).

About this study

Official title: A Prospective Randomized Trial of Mini Incision and 2-Incision Total Hip Arthroplasty

The purpose of the research is to determine if there is a difference between two of the commonly used less invasive techniques (surgical methods that use a smaller incision or cut in the skin) used to perform total hip arthroplasty (replacement of your painful hip with a new ball and socket). It is unclear which of these techniques is associated with a faster recovery and lower risk of complications.

Read the detailed description

Recently, surgical techniques and surgical instruments have been developed to limit the dissection required to perform a total hip arthroplasty. Proponents of these procedures feel that it is associated with less perioperative blood loss, less pain and an accelerated recovery while critics have raised concerns that the more limited exposure may negatively impact component position and increase the risk of perioperative complications. Among less invasive surgical techniques, two of the different approaches utilized include a "mini-incision" posterior approach which aims to limit the amount of dissection associated with a standard posterior approach to the hip and a 2-incision technique which seeks to further limit soft tissue disruption by taking advantage of intermuscular planes and the use of fluoroscopic guidance.

While the mini-posterior approach utilizes an abbreviated exposure which is familiar to most surgeons, the 2-incision approach is a more novel approach and critics of this approach feel that its technically demanding nature may be associated with a higher risk of complications and component malposition. Proponents of the 2-incision approach feel that this approach is less invasive, more muscle sparing and leads to substantial improvements in patient rehabilitation and recovery with potential longer-term benefits in terms of improved function. The goal of this project is to compare the use of a mini-incision posterior approach and the 2-incision approach in primary total hip arthroplasty via a prospective randomized trial.

Questions about this trial

What is this clinical trial studying?

A study testing Mini Incision Approach and 2 Incision Approach in people with Osteoarthritis, run by Rush University Medical Center 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 4 inclusion and 11 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 31 Aug 2012. 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?

Pain scores (time frame: Daily for 6 weeks postoperatively). 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 NCT00594893, which also lists 1 linked publication.

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 31 Aug 2012.
