Single center, pilot, randomized, controlled clinical trial to assess metabolic and morphological images between two types of cemented stem prostheses in patients undergoing total hip arthroplasty surgery during a 2-year follow up period.


Single center, pilot, controlled clinical trial to assess metabolic and morphological images of patients undergoing total hip arthroplasty surgery randomized to the thick layer technique (Exeter hip stem model) or to the "French paradox" technique (Mller straight stem model).

Participants will be performed a plain radiography and a SPECT-CT at 3, 6, 12 and 24 months of the intervention. SPECT-CTs will be performed in addition to the usual medical care complementary imaging exams. The SPECT will require the administration of the 99mTechnetium-methylene diphosphonate (99mTc-MDP) radiopharmaceutical (useful to assess bone metabolism) and its combination with a CT scan (SPECT-CT) allows a combined metabolic and morphological study.

Condition Arthropathy of Hip
Treatment Total hip arthroplasty using the Exeter V40 cemented femoral stem, Total hip arthroplasty using the Müller Straight Stem
Clinical Study IdentifierNCT05010733
