Abstract:

OBJECTIVE: To evaluate the effect of bone cement prosthesis by retrieving literatures and clinical validations.
METHODS: With the key words “total hip replacement, prosthesis, bone cement” in Chinese and English, articles were searched in VIP and Pubmed databases published between January 1998 and December 2009. Articles related to cemented and cementedless prosthesis were included. Repetitive articles and Meta analysis were excluded. The questions were discussed, including classification of artificial joint replacement, development of cemented hip prosthesis materials, treatment effect and clinical validation of cemented hip prosthesis materials, anatomic features of calear femorale and operation of hip joint replacement. In addition, 55 cases undergoing total hip replacement with cemented prosthesis in Qiannan Prefecture People's Hospital were analyzed.
RESULTS: Artificial joint replacement includes cemented and cementedless prosthesis. Cemented prosthesis is applicable for osteoporotic and elderly patients. Cementedless prosthesis can be used for middle-aged or young patients. As the shear strength of metal and bone cement surface is bad, novel bone cement modifies the prosthesis surface to enhance the shear strength. Clinical results showed that during the follow up of 12 months to 6 years, there were 39 cases of excellent, 13 of good and 3 of fair according to Harrisyg scores. Postoperative X-ray showed hip pain in 3 patients, prosthesis prolapse in 1, prosthesis loosening in 1 and dislocation in 1. No infection or femoral fracture was detected.
CONCLUSION: With development of various novel bone cement materials, the performance of bone cement is improving, and may become ideal bone substitutes.
