Multi-centre Study to Assess Long-term Safety and Efficacy of the Silent™ Hip Prosthesis in Primary THR

April 20, 2016 updated by: DePuy International

A Non-comparative, Multi-centre Study to Evaluate the Safety and Efficacy of the DePuy Silent™ Hip Prosthesis in Primary Total Hip Replacement

The purpose of this study is to determine if the Silent™ hip is effective in the treatment of patients with hip joint disease requiring a total hip replacement. Patients who enter the study will be evaluated at regular intervals following hip surgery using patient, clinical and x-ray assessments. A subset of patients will undergo scans to allow the bone mineral density of the bone surrounding the implant to be monitored

Indicates the current recruitment status or the expanded access status.
Terminated

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The purpose of this study is to determine if the Silent™ hip, when used as part of an artificial hip joint, is effective in the treatment of patients with hip joint disease requiring a total hip replacement. Patients who enter the study will be evaluated at regular intervals following hip surgery using patient, clinical and x-ray assessments. A subset of patients will undergo scans to allow the bone mineral density of the bone surrounding the implant to be monitored

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

14 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Male or female subjects, aged 18 years or above at the point of screening for participation.
  • Subjects who are able to give voluntary, written informed consent to participate in this clinical investigation and from whom consent has been obtained.
  • Subjects who, in the opinion of the Clinical Investigator, are able to understand this clinical investigation, co-operate with the investigational procedures and are willing to return to the hospital for all the required post-treatment follow-ups.
  • Subjects with non-inflammatory osteoarthritis of the hip who require a primary total hip replacement and are considered suitable for a cementless femoral and acetabular component.

Exclusion Criteria:

  • Subjects who, in the opinion of the Investigator, have an existing condition that would compromise their participation and follow-up in this study.
  • Women who are pregnant.
  • Subjects who are known drug or alcohol abusers or with psychological disorders that could affect follow-up care or treatment outcomes.
  • Subjects who have participated in a clinical study with an investigational product in the last 6 months. This exclusion does not apply to those subjects who are participating in the pilot investigation of the DePuy Silent Hip (CT01/27)
  • Subjects who are currently involved in any injury litigation claims.
  • Subjects who have osteonecrosis of the femoral neck
  • Subjects with significant bone loss or gross deformity in the region of the neck of the femur as identified on the pre-operative radiographs, where in the Investigator's opinion, there could be considerable migration of the DePuy Silent Hip or a significant chance of fracture of the femoral shaft and/or the lack of adequate bone to support the DePuy Silent Hip.
  • Subjects with a Charnley C classification.
  • Subjects with an active local or systemic infection.
  • Subjects with loss of musculature, neuromuscular compromise or vascular deficiency in the affected limb rendering the arthroplasty procedure unjustified.
  • Subjects with Paget's disease
