Sistema de Hombro Sin Vástago OsseoFit (Anatómico)

29 de septiembre de 2026 actualizado por: Zimmer Biomet

Estudio de Seguimiento Clínico Postcomercialización del Sistema de Hombro Sin Vástago OsseoFit (Anatómico)

The purpose of this clinical research protocol is to evaluate the safety, efficacy, and long-term outcomes of the OsseoFit Stemless Shoulder System (Anatomic) in patients with a primary diagnosis of osteoarthritis. The study aims to assess the intraoperative characteristics, postoperative complications, functional outcomes, and radiographic findings associated with the use of the stemless implant system. Ultimately, this research aims to improve patient outcomes, enhance surgical techniques, and inform clinical decision-making in the treatment of shoulder pathology.

Descripción general del estudio

Descripción detallada

The objectives of this study are to confirm the safety, performance, and clinical benefits of the OsseoFit Stemless Shoulder System (implants and instruments) in primary total shoulder arthroplasty (anatomic). Safety of the system will be assessed by monitoring the frequency and incidence of adverse events. The performance and clinical benefits will be evaluated by assessment of the overall pain and functional performance, survivorship, quality of life, and radiographic parameters for all enrolled study participants.

The primary endpoint is the improvement in the American Shoulder and Elbow Surgeons (ASES) Shoulder score between the pre-operative period (baseline) and 2 years of follow up.

The key secondary endpoint is the survival of the implant system at 10 years, which is based on removal of any part of the study device and will be determined using Kaplan Meier method.

The safety of the system will be assessed by monitoring the frequency and incidence of adverse events.

The secondary endpoint evaluation will also assess the overall pain/functional performance (ASES, Constant Murley Shoulder Score, and ROM), quality of life, satisfaction, and radiographic parameters of all enrolled study participants.

Población de estudio

The OsseoFit Stemless Shoulder implants are intended for shoulder joint arthroplasty. OsseoFit™ Stemless Shoulder humeral components have a porous surface and are indicated for uncemented biological fixation applications.

Compatible Glenoid components are intended to be implanted with bone cement. The porous posts may be inserted without bone cement.

Compatible Comprehensive Convertible Glenoid components are intended for cementless applications with the addition of screw fixation.

Periodo de tiempo
the American Shoulder and Elbow Surgeons (ASES) Shoulder Score
Periodo de tiempo: 2 years

The primary endpoint is the American Shoulder and Elbow Surgeons (ASES) Shoulder Score. Improvement from baseline to 2 years will be evaluated using the overall mean change, with effectiveness demonstrated if the mean improvement exceeds the MCID of 10.8 points. The primary endpoint analysis will use the ITT population with all available data and no imputation. Hypotheses: H0: μCFB ≤ 10.8; H1: μCFB > 10.8, where μCFB is the mean ASES change (2 years minus baseline). The MCID of 10.8 was established using the 0.5 SD distribution method based on psychometric evaluation of ASES scores from 3,667 shoulder arthroplasty patients with ≥2-year follow-up.

10 Years
ASES
Periodo de tiempo: 6 Week, 6 Month, 1 Year, 2 Year, 3 Year, 5 Year, 7 Year, 10 Year

The American Shoulder and Elbow Surgeons Shoulder Score (ASES) was designed to assess the condition of the shoulder, regardless of disease pathology. It consists of two equally weighted components: pain (50 points) and function/disability (50 points). The pain sub-score is calculated from a single question VAS tool. The function/disability sub-score is calculated from a 10 question, 4-point Likert scale. Scores range from 0 to 100 with a score of 0 indicating a worse shoulder condition and 100 indicating a better shoulder condition.

Constant Murley
Periodo de tiempo: 6 Week, 6 Month, 1 Year, 2 Year, 3 Year, 5 Year, 7 Year, 10 Year

The Constant-Murley score (CMS) is a patient-reported outcome questionnaire that comprises outcome measures of freedom from pain (15 points), full range of function (20 points), active range of movement (40 points), and full strength (25 points). The total score is an aggregate of the individual outcome measures. The minimum score is 0 (worst outcome) and the maximum score possible is 100 points (best outcome).

EQ-5D-5L composite
Periodo de tiempo: 6 Week, 6 Month, 1 Year, 2 Year, 3 Year, 5 Year, 7 Year, 10 Year

The 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, self-care, daily/usual activities, pain/discomfort and anxiety/depression. For EQ-5D-5L, each question can be answered in five ways, indicating no, slight, moderate, severe or extreme pain. In the derived EQ-5D-5L score, the highest score is 1 and the lowest score is -0.573. Negative numbers correspond to a self-assessed health state worse than being dead.

The VAS is a vertical scale ranging from 0 ('The worst health you can imagine') to 100 ('The best health you can imagine') where the patient reports his/her self-rated health.

6 Week, 6 Month, 1 Year, 2 Year, 3 Year, 5 Year, 7 Year, 10 Year
SANE
Periodo de tiempo: 6 Week, 6 Month, 1 Year, 2 Year, 3 Year, 5 Year, 7 Year, 10 Year

The Single Assessment Numerical Evaluation (SANE) score is a single point, subjective estimate of a patient's condition. The patient is asked to rate their progress and current state on a scale of 0% - 100% of normal (e.g. How would you rate your shoulder today as a percentage of normal?) with 100% being considered normal.

6 Week, 6 Month, 1 Year, 2 Year, 3 Year, 5 Year, 7 Year, 10 Year
Patient Satisfaction
Periodo de tiempo: 6 Week, 6 Month, 1 Year, 2 Year, 3 Year, 5 Year, 7 Year, 10 Year

Single-item satisfaction question - How satisfied are you with your shoulder replacement (so far)? 5 answer choices: Very Satisfied, Satisfied, Neutral, Dissatisfied, Very Dissatisfied

Radiographic Performance [Radiolucency]
Periodo de tiempo: 6 Week, 6 Month, 1 Year, 2 Year, 3 Year, 5 Year, 7 Year, 10 Year

X-rays will be evaluated for radiolucency lines to show the number of subjects with radiolucency. Radiolucency refers to structures that are less dense and permit the x-ray beam to pass through them. Radiolucent structures appear dark or black in the radiographic image.

Radiographic Performance [Osteolysis]
Periodo de tiempo: 6 Week, 6 Month, 1 Year, 2 Year, 3 Year, 5 Year, 7 Year, 10 Year

X-rays will be evaluated for osteolysis to show the number of subjects with osteolysis. Osteolysis is a progressive condition where bone tissue is destroyed. In this process, bones lose minerals (mostly calcium), softens, degenerates and become weaker.

Radiographic Performance [Heterotopic Ossification]
Periodo de tiempo: 6 Week, 6 Month, 1 Year, 2 Year, 3 Year, 5 Year, 7 Year, 10 Year

X-rays will be evaluated for heterotopic ossification to show the number of subjects with heterotopic ossification. Heterotopic ossification refers to the presence of bone in soft tissue where bone normally does not exist (extraskeletal bone).
