Abstract:
BACKGROUND:After the initial hip replacement, aseptic or infective loosening and subsidence of the prosthesis, acetabular wear, pain, osteolysis and other factors may lead to the loss of prosthesis stability and loss of joint function, which are the common cause of hip arthroplasty. Among the hip arthroplasty, acetabular lateral reconstruction is essential and largely determines the success or failure of revision surgery. ＜br> OBJECTIVE:To explore the present situation of reconstructing acetabulum after total hip arthroplasty. ＜br> METHODS:A computer-based online search of PubMed database (http://www.ncbi.nlm.nih.gov/PubMed) between January 1998 and March 2014, and CNKI database (http://www.cnki.net/) from January 2003 to March 2014 was undertaken for the articles about reconstructing acetabulum after total hip arthroplasty. The key words were“artificial joint, reconstruction, acetabular lateral reconstruction, current situation”in Chinese and“reconstructed acetabulum, total hip arthroplasty”in English. Article about hip reconstruction, acetabyular reconstruction, bone defect reconstruction, prosthesis choice and reconstruction, and soft tissue balance were also selected. Repetitive researches were excluded. ＜br> RESULTS AND CONCLUSION:According to inclusion criteria, 26 articles were involved in this study. A perfect acetabular revision should achieve the fol owing goals:stabilize acetabular prosthesis after acetabular revision;recover hip rotation center and biomechanical properties;repair acetabular bone defects and increase hip bone. Adequate preparation before surgery is an important prerequisite for the success of surgery and good results, aseptic and septic loosening or subsidence of the prosthesis, as wel as acetabular wear and tear are common causes of hip revision. Intraoperative reconstruction of acetabular anteversion and camber angles, acetabular rotation center reconstruction, reconstruction of acetabular bone defects, selection of reconstruction of acetabular prosthesis, and reconstruction of soft tissue balance are the core technologies of reconstructing acetabulum after total hip arthroplasty.
