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 objective of this post market surveillance study is to obtain outcome data on the Fitmore Hip Stem by analysis of standard scoring systems, radiographs and adverse event records, and thus to assess the long-term performance and safety of this implant.

The Fitmore Hip Stem is a short and curved uncemented stem that allows preservation of the greater trochanter and of the gluteal muscles.

Indication/Target Population: Patients suffering from severe hip pain and disability requiring total hip arthroplasty.

Study Design: A multi-centre, non-comparative, prospective post-marketing study.

Targeted Number of Subjects: 500. Data Collection: Collection of preoperative, intra-operative and immediate post-operative data; follow-up visits at 6-12 weeks, 1, 2, 3, 5, 7 and 10 years post-operatively.

Recruitment period: 24 months. Clinical Assessments: Evaluations will be made using the Harris Hip Score, the Oxford Hip Score, the SF-12 Physical and Mental Health summary measures, the EQ-5D (EuroQol) and radiographically.

Safety Assessments: Safety will be assessed by appropriate recording and reporting of adverse events throughout the study. The Fitmore Hip Stem is CE marked, commercially available and has been pre-clinically tested.

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

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Harris Hip Score
Time Frame: Preop, 6 - 12 weeks, 1 year, 2 year, 3 year, 5 year, 7 and 10 years
The Harris hip Score (HHS) is an outcome measure that includes a series of questions answered by the patient and physical examinations recorded by a qualified health care Professional. The HHS covers four domains: pain (one item, 0-44 points), function and functional activities (seven items, 0-47 points), absence of deformity (one item, 0-4 points) and range of motion (one item, 0-5 points). The total score can vary from a range of 0 - 100. The outcome score can be categorized as Excellent: 90-100; Good: 80-90; Fair: 70-80; Poor: < 70.
Preop, 6 - 12 weeks, 1 year, 2 year, 3 year, 5 year, 7 and 10 years
Radiographic Evaluations
Time Frame: 6 - 12 weeks and 7 years
Radiographic evaluation was assessed at the time points listed below in order to identify potential adverse events.
6 - 12 weeks and 7 years
Survivorship
Time Frame: 10 years post surgery
The primary endpoint for this study is implant survival at 10 years which is assessed by revision of the Fitmore Hip Stem calculated using the Kaplan-Meier Survival Estimation. The survivorship with Kaplan-Meier (K-M) was calculated at 10 year for endpoint revision of any component.
10 years post surgery

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
EQ5D
Time Frame: Preop, 6-12 weeks, 1 Year, 2 Year, 3 Year, 5 Year, 7 Year and 10 Year
The EuroQol 5 Dimension (EQ-5D) is a standardized Instrument widely used to measure health status. It is a self reported assessment about the patient's quality of life composed of two parts: a questionnaire and a visual analogue scale (VAS). The questionnaire includes 5 questions referring to mobility, selfcare, daily activities, pain/discomfort, and anxiety/depression. Each question can be answered in five ways, indicating no, slight, moderate, severe problems or inability to complete the task. The EQ-5D-5L score ranges from -0.59 to 1, where 1 is the best possible health state. The Visual Analogue Scale (VAS) is a vertical scale ranges from 100 ('The best health you can imagine') to 0 ('The worst health you can imagine') where the patient reports his/her self-rated health.
Preop, 6-12 weeks, 1 Year, 2 Year, 3 Year, 5 Year, 7 Year and 10 Year
SF-12 Physical and Mental Functional Scores
Time Frame: Preop, 6-12 Weeks, 1 Year, 2 Year, 3 Year, 5 Year, 7 Year and 10 Year
The SF-12 is a multipurpose short-form (SF) generic measure of health status. It consists of twelve questions that measure eight health domains to assess physical and mental health. Physical health-related domains include General Health (GH), Physical Functioning (PF), Role Physical (RP), and Body Pain (BP). Mental health-related scales include Vitality (VT), Social Functioning (SF), Role Emotional (RE), and Mental Health (MH). Scores ranges from 0 to 100, with higher scores indicating better physical and mental health functioning.
Preop, 6-12 Weeks, 1 Year, 2 Year, 3 Year, 5 Year, 7 Year and 10 Year
Oxford Hip Score
Time Frame: Preop, 6-12 Weeks, 1 Year, 2 Year, 3 Year, 5 Year, 7 Year and 10 Year
The Oxford Hip Score (OHS) is a patient-reported outcome measure that was developed to specifically assess the patient's perspective of outcome following THA. The OHS consists of twelve questions covering function and pain associated with the hip. To calculate the total score, each response is scored from 0 (warst outcome) to 4 (best outcome) and the sum of all 12 items is reported with a maximum of 48, representing the best score possible. The Score ranges from 0 - 100 and the outcome score can be categorized as Excellent: > 41; Good: 34 - 41; Fair: 27 - 33; Poor: < 27.
