According to the results reported on ClinicalTrials.gov, this trial enrolled 20 people who received a hip replacement implant called the MIS (Mini Stem). All participants started the study, but only 10 completed it — the other 10 did not finish, though the reasons are not detailed in the reported data. The trial was measuring bone mineral density (BMD) — that is, how dense or strong the bone is — in the thigh bone (femur) around the implant over time, using a type of scan called DEXA (Dual Energy X-Ray Absorptiometry). The thigh bone was divided into seven zones, and bone density in each zone was measured before surgery and then again at 3 months, 6 months, 1 year, and 2 years after the procedure. The reported data shows the average bone density readings (measured in grams per square centimetre) across the seven zones at each time point. Before surgery, the readings across the seven zones ranged from 0.8 to 2.0 g/cm². At 3 months after surgery, they ranged from 0.8 to 2.1 g/cm². The reported figures at 6 months, 1 year, and 2 years were broadly similar, ranging from 0.8 to approximately 2.2 g/cm² depending on the zone and time point. The outermost zone consistently recorded the lowest density reading (0.8 g/cm²) across all time points, while the middle zones recorded the highest readings. The reported data also includes a secondary measure called the Harris Hip Score, which is a tool scored from 0 to 100 that doctors use to assess how a person is functioning before or after hip surgery — a higher score means better function. Before surgery, the overall average score was reported as 49.5 out of 100, which falls in the "very poor" range on the scale. No post-surgery Harris Hip Score figures were included in the submitted results data, so those cannot be described here. These are the results as reported to ClinicalTrials.gov.

Who might be able to join this trial:
- You have a hip condition that means you need a total hip replacement surgery.
- You are willing to give your consent to take part in the study.
- You are able to stay involved for the full length of the study.
- You are in generally stable health, and any heart, lung, blood, or other health conditions you may have are being managed and under control.
Who may not be able to join:
- You have been found to have bones that are not strong enough to support the implant.
- You have previously had major surgery (not including keyhole/arthroscopic surgery) on the hip being studied.
- You have physical, emotional, or neurological (nervous system) conditions that might make it difficult to follow the recovery programme or attend follow-up appointments.
- You have a known allergy or sensitivity to any of the materials used in the device.
