Abstract:

 BACKGROUND: The prosthesis fusion rate after total hip replacement is closely related to the reconstruction process of bone, which is affected by the factors around the implant of patient. Trace elements are strongly associated with the ossification. Thus, the content of trace elements in proximal femur may affect the bone fusion and survival rate of the prosthesis.

 
OBJECTIVE: To analyze the correlation of trace elements and bone fusion surrounding the prosthesis in proximal femur.
METHODS: Bone samples were obtained from the discarded metaphysis region of the proximal femur in 24 patients with primary total hip replacement. Trace element (calcium, magnesium, zinc, parathyroid hormone, activated vitamin D3) contents were detected after vitro cell culture. Bone mineral density was tested surrounding the prosthesis at 1 week, 3 and 6 months after replacement by dual energy X-ray absorption method with a bone density meter. The difference in trace elements was compared in patients at different ages and different genders. The correlation between above five kinds of trace elements and bone mineral density was analyzed.
RESULTS AND CONCLUSION: No significant difference in trace element contents was detected in different age groups and different gender groups (P > 0.05). Zinc content was positively correlated with parathyroid hormone and magnesium contents (P < 0.05). Zinc was positively associated with bone mineral density in the region 7 (P < 0.05). The further studies concerning the trace elements in proximal femur can be used to predict and intervene in the longevity of hip prosthesis.
