PINNACLE® DM RSA Study

NCT ID: NCT05357664

Last Updated: 2024-04-18

Basic Information

• Recruitment Status: TERMINATED
• Clinical Phase: NA
• Total Enrollment: 11 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2022-10-06
• Study Completion Date: 2023-02-09

Brief Summary

The primary objective is to establish the mean superior cup migration of the PINNACLE® Dual Mobility Construct using model-based RSA over the first two years post-implantation. The primary endpoint is the mean vertical subsidence (Y translation, also known as superior cup migration) at 2 years as measured with RSA. Additionally, the data from this study will be compared to historical PINNACLE® data obtained in study DSJ_2018_02.

Exclusion Criteria

1. Individuals have active local or systemic infection.

2. Individuals who have loss of musculature, neuromuscular compromise or vascular deficiency in the affected limb rendering the procedure unjustified.

3. Individuals with poor bone quality, such as osteoporosis, where in the surgeon's opinion, there could be considerable migration of the prosthesis or a significant chance of bone fracture and/or the lack of adequate bone to support the implant(s).

4. Individuals with Charcot's or Paget's disease.

5. Individuals who, in the judgement of the investigator, would not be a candidate for protocol allowable components to be used for their THA.

6. Women who are pregnant or lactating.

7. Individuals who have had a contralateral hip that was implanted less than 6 months prior to the time of consent into this study or individuals that expect to have a contralateral hip implanted in the 6 months following the time of consent into this study.

8. Individuals that have amputations in either leg that would impact rehabilitation following surgery.

9. Individuals who are bedridden per the Investigators determination

10. Individuals that have participated in a clinical investigation with an investigational product (drug or device) in the last three months.

11. Individuals currently involved in any personal injury litigation, medical-legal or worker's compensation claims.

12. Individuals, in the opinion of the Investigator, who are drug or alcohol abusers or have a psychological disorder that could affect their ability to complete patient reported questionnaires or be compliant with follow-up requirements.

13. Individuals diagnosed and taking prescription medications to treat a muscular disorder that limits mobility due to sever stiffness and pain such as fibromyalgia or polymyalgia.

14. Subject has a medical condition with less than 2 years life expectancy.

15. Individual has a BMI >45 kg/m2.

16. Individuals who require revision arthroplasty and have a well-fixed non-DePuy Synthes femoral stem or a well-fixed DePuy Synthes femoral stem that does not have a polished neck
