What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing This study
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This trial tests whether adding screws to secure the cup part of a hip replacement makes a difference in how well the implant stays in place. Participants aged 65-80 with hip osteoarthritis will receive a hybrid hip replacement, and half will get screws while the other half won't. Using advanced CT imaging, the study tracks implant movement over time to predict long-term survival. The goal is to see if screws are necessary or if the press-fit cup alone is enough.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Total hip arthroplasty (surgery) with or without ancillary acetabular screws
What this could lead to
If successful, this could help surgeons decide whether screws are needed for hip implants, potentially improving long-term implant survival and reducing complications.
What could go wrong
This is a small, early-stage trial with 60 participants, so results may not apply to all patients. There are standard surgical risks like infection, implant loosening, or complications from anesthesia.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * • Patients with primary hip osteoarthritis between the age of 65 and 80 years at time of surgery * Patients requiring primary total hip replacement * Patients who understand the conditions of the study, are willing to, and able to comply with the postoperative scheduled clinical and radiographic evaluations Exclusion Criteria: * • Patients who are unable to provide informed consent * Patients who require revision hip arthroplasty * Patients who have had a previous osteotomy or osteosynthesis of the femur or acetabulum * Patients with metabolic bone disease, other than osteoporosis * Patients with inflammatory arthritis * Obese patients where obesity is severe enough to affect the patient's ability to perform activities of daily living (BMI \> 40) * Patients with active or suspected infection * Patients with malignancy * Patients unable to cooperate caused by language or psychosocial conditions
