The goal of this prospective observational study is to evaluate whether the use of a Custom-Made Articulating Spacer (CUMARS) can achieve satisfactory functional outcomes and effective infection control in patients undergoing two-stage revision for infected hip joints.
The main questions it aims to answer are:
Does the use of CUMARS provide acceptable functional outcomes during the interim period and after definitive reimplantation?
Does CUMARS result in effective infection eradication with acceptable perioperative parameters and complication rates?
Participants will:
Undergo first-stage removal of the infected hip prosthesis and implantation of a Custom-Made Articulating Spacer
Receive targeted systemic antibiotic therapy based on culture results
Be followed up clinically and radiologically to assess function, complications, and infection status
Undergo second-stage definitive hip reimplantation after confirmation of infection eradication
