ABSTRACT
BACKGROUND:
Prosthesis friction interface is a hot focus in the study of total hip joint. Polyethylene wear particles induced inflammatory reaction, resulting in osteolysis surrounding the prosthesis and prosthesis loosening. To reduce polyethylene wear, ceramics-ceramics and ceramices-polyethylene friction interfaces were selected. High cross-linked polyethylene material with high intensity was selected. In young patients with large activity amount, the application of ceramic head is a great progress.OBJECTIVE:
To assess the safety of large-diameter alumina ceramic matrix composites (BIOLOX? delta) bal on third-generation highly cross-linked polyethylene (Trident X3, Stryker, Mahwah, NJ) total hip arthroplasty in young patients, and to perform radiological measurements of high cross-linked polyethylene wear rate in the shortest two years after fol ow-up.METHODS:
From July 2008 to June 2010, wear analysis of 30 cases aged less than 60 years with 32 hips with 36-mm BIOLOX ? delta ceramic femoral heads (CeramTec, Plochingen, Germany) on highly cross-linked polyethylene was performed in the 455 Hospital of Chinese PLA using Roman software (Robert Jones&Agnes Hunt Orthopaedic Hospital, Oswestry, United Kingdom). The mean age of patients was 56.8 ± 6.5 years. RESULTS ANDCONCLUSION:
Fol ow-up was conducted from 2 to 3.7 years old. There were no imaging evidences, such as dislocation, the bal head fracture or joint loosening or osteolysis. Mean Harris score was increased from (19.9±7.3) (11-36) before replacement to (35.3±5.4) at 6 months after replacement. The mean wear rate was (0.022±0.11) mm/year after run-in period. These data indicated that large-diameter ceramic head articulation against highly cross-linked polyethylene in young patients would have high safety for joint dislocation, prosthesis fragmentation and low wear rates.
