Study summary

The study is a multi-center, prospective, non-controlled, consecutive cohort post market surveillance study. The objective of this study is to obtain survival and clinical outcome data on the Hyperion® system in primary and revision total hip arthroplasty.

Read the detailed description

This multi-center, prospective, non-controlled, consecutive cohort post market surveillance study will serve the purpose of confirming long-term safety and performance of the Hyperion® system. The performance of the Hyperion® THA System will be evaluated using standard scoring systems (Merle d'Aubigné Score, HOOS Score). Safety will be evaluated by adverse event reporting.

The study will be performed at 6 sites, enrolling in total 70 patients. Follow-up visits are planned after 3 to 6 month, 1, 2 and 5 years. The scores will be filled in pre-operatively and post-operatively until 5 years. In order to obtain mid- to long-term patient satisfaction data the patient questionnaire will be send to the patient at 7 and 10 years, additionally. Xrays will be done pre-operatively, immediate post-operatively and at each of the Follow-up visits.

Study population

Because of the studiesindications it is assumed that patients have a relatively high (> 60 Jahre) age at the time of their operations. Therefore a higher letality and a higher drop-out-rate is expected compared to study populations of primary hip replacement. To reach the necessery power for this clinical study at least 70 patients should be recruited.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Patient age at least 18 years
  • Fully conscious and capable patients
  • Signed
  • Stationary treatment
  • Merle d'Aubigné \< 12 Points, WOMAC Score > 25 Points
  • Patients with at least one of the following indications:

Indications for primary hip replacement:

  • Non-inflammatory diseases of the joints such as osteoarthritis and avascular necrosis (head necrosis)
  • Rheumatoid arthritis
  • Functional deformities
  • Provision of non-endoprosthetic previous operations of the hip joint (e.g., transposition osteotomies)
  • Treatment of pseudarthrosis, femoral neck and trochanter fractures, as well as fractures of the proximal femur affecting the head, which can not be treated by other techniques

Revision THA:

  • Revision of endoprosthesis-treated hips as a result of septic or aseptic loosening, sub- and periprosthetic fractures or material failure (eg fracture of the prosthesis)
  • Bridging of large bone defects (precondition: suitable proximal bone situation for a stable anchorage), i.e. for tumors

Exclusion criteria

Exclusion Criteria:

  • Infections
  • Patients under 18 years
  • Pregnant or breastfeeding patients
  • Known alcohol abuse (at least 20 g alcohol per day for women and at least 40 g per day for men) or drug abuse
  • Legal incapacity or restricted capacity
  • Participation in another clinical trial within the last 30 days or planned participation in another clinical trial within the next 3 months
  • Patients who are unable to attend to follow-up
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

What researchers measure

Primary outcomes

  1. Pain and Walking Ability Determined by a Merle d' Aubigné Score Increase of >4 Points.

    Pain and walking ability determined by a Merle d' Aubigné Score (MdA) increase of \>4 points compared to the pre-operative score points. The patients were evaluated by the Merle d'Aubigné hip score, which evaluates pain, gait and mobility, on a scale of 1 to 6 for each item, where 1 indicates the worst and 6, the best state of the patient. The value of each item is summed to a total score. The total minimum score reached is 3, and the maximum is 18. Higher scores mean a better outcome.

    Time frame: baseline/Pre-op and 2 years (+/- 2 months)

  2. Implant Survival Measured by the Number of Revisions.

    Implant survival is measured by the number of revisions and analysed by the Kaplan Meier method.

    Time frame: 2 years (+/- 2 month)

  3. WOMAC Score Value Decrease at 2-years in Min. 25 Points Compared to the Pre-operative WOMAC Score Value

    at 2-years post op, WOMAC score (Western Ontario and McMaster Universities Arthritis Index) has to be at least 25 points lower compared to preop values Scale: min 0-Max 100; Higher values mean worse outcome

    Time frame: baseline/Pre-op and 2 years (+/- 2 months)
