About this study

Official title: A Prospective, Randomized Study of Summit™ Porocoat® Versus Summit™ DuoFix™ HA in Cementless Total Hip Arthroplasty

Prospective, randomized study of Summit Porocoat versus Summit DuoFix HA in total hip arthroplasty

Read the detailed description

Hydroxyapatite (HA) is a bioactive ceramic that resembles the natural inorganic mineral content of bone, and as such is a highly osteoconductive material. The purpose of this study is to compare an HA coated and uncoated prosthesis.

Being tested
non-coated femoral hip stem, coated femoral hip stem
Keywords
Total Hip Replacement
Medical subject headings
Osteoarthritis, Arthritis, Rheumatoid, Osteonecrosis

What is being measured

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

  1. Harris Hip Score (HHS)

    The Harris Hip scoring system assigns a numeric value to responses from patients and assessments made by a surgeon. A score of 90-100 is excellent, 80-90 is good, 70-80 is fair, 60-69 is poor, and 60 or below is failed. The patient records the following: pain level, need for assistance when walking, presence of a limp, distance able to walk, ability to put on shoes and socks, climb stairs, use public transportation and the length of time one is able to comforatably sit in a chair are all scored. The doctor assesses patient hip function by testing flexion, extension, adduction and abduction.

    Measured: Preoperative, 6, 12, 24, 36, 48, and 60 months

Secondary outcomes (1)
  1. Medical Imaging as a Secondary Outcome Inclusive of All Post-operative Intervals for All Participants at Study Closure.

    Medical imaging as a secondary outcome inclusive of all post-operative intervals for all participants at study closure. This measure is a percentage of the overall Participants with a specific radiographic outcome. Measurements were made by an Independent Radiographic Reviewer (IRR) and include assessments made based on protocol defined radiographic success criteria that includes Subsidence (10 mm), Osseointegration, Radiolucency > 2 mm in any zone, Complete Circumferential Radiolucencies, Spot-Welds (AP View) p < .10, Spot-Welds (Lateral View) p < .10, Cortical Hypertrophy (AP View), Cortical Hypertrophy (Lateral View)

    Measured: Postoperative, 6, 12, 24, 36, 48 and 60 months

Questions about this trial

What is this clinical trial studying?

A study testing non-coated femoral hip stem and coated femoral hip stem in people with Osteoarthritis and Rheumatoid Arthritis, run by DePuy Orthopaedics 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 3 inclusion and 7 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: stopped early, as of the sponsor's last update on 19 Jul 2022. 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?

Yes. Results are posted in the registry (first posted 10 Mar 2010). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Harris Hip Score (HHS) (time frame: Preoperative, 6, 12, 24, 36, 48, and 60 months). 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 19 Jul 2022.
