Abstract:
      Purpose: To investigate the potential correlation between two different types of hip fractures and serum calcium levels. Methods: We consecutively studied 101 cases of femoral neck fracture and 95 cases of femoral intertrochanteric fracture between January 2011 and December 2013. Fasting blood samples were taken and serum calcium measurements were performed respectively in three periods: the time of admission, postoperation, and discharge. Creatinine, alkaline phosphatase and albumin were also analyzed. Results: Considering the levels of serum calcium between two groups at the time of admission, postoperation and discharge, there was significant difference at admission and discharge (p < 0.05), while there was no significant difference at the time of postoperation (p > 0.05). The magnitude of serum calcium fluctuation was larger in femoral neck group than femoral intertrochanteric group. Concerning alkaline phosphatase and albumin levels at admission, there was no significant difference between two groups (p > 0.05). Conclusion: The capability of reservation and restoration of serum calcium in patients with femoral neck fracture is better than that in patients with femoral intertrochanteric fracture. A low serum calcium level may be susceptible to femoral intertrochanteric fracture.
