Cemented or uncemented hemiarthroplasty for the treatment of femoral neck fractures?

摘要

We read with interest the article by Yli-Kynyy et al. (2014) on the use of cemented versus cementless hemiarthro-plasty in the treatment of femoral neck fractures. However, we would like to know some aspects of the study which would be of help to orthopedic surgeons. The authors found an increased mortality rate directly related to the use of cemented hemiarthroplasty and fat embolus syndrome in their study. However, the mortality after hip fracture is multifactorial including operative delay (Ratcliff et al. 2008). In the present study the time of the fracture event and start of the surgical intervention were not presented. The second point is that hip fracture is associated with a substantial increase in mortality with co-existing chronic renal failure (Karaeminogullan et al. 2007). We found no information about the co-existence of renal disease.
