Abstract
BACKGROUND: In total hip arthroplasty, acetabular defects are common, for the reconstruction of a stable and solid acetabulum, the acetabular reconstruction is often required during the replacement process.OBJECTIVE: To investigate the early effect of the short term results of titanium mesh fixed by screws combined with a cemented acetabular cup in acetabular reconstruction. METHODS: Twenty-three patients treated with acetabular reconstruction by screw fixed titanium mesh combined with a cemented acetabular cup were selected. The pain history was 1 to 3 years. Harris scores before operation were 20-48 with an average score of 34. X-ray plain film was used to evaluate theacetabular prosthesis loosening standards after reconstruction for the radiographic evaluation and Harris score of regular fol ow-up. RESULTS AND CONCLUSION: Al the patients were fol owed-up for 1-3 years and average in 24 months without losing. The Harris score at 3 months after operation was higher than that before operation, and the hip activity at 2 years after operation was higher than that before operation, and the difference was significant (P <0.05). Two patients stil had leg length discrepancy, one patient with dislocation after squatting, and recovered after conservative treatment. The last fol ow-up showed there were no early infection, dislocation and pelvic discomfort. Radiographic results showed that there was no aseptic loosening and displacement of the acetabular cap and there was no fracture on titanium mesh. Screw fixed titanium mesh combined with a cemented cup is satisfactory process in the treatment of hip revision in over 65 years old patients, and the long-term effects are needed to be further fol owed-up and observed.关键词
