BACKGROUND AND PURPOSE We have developed an individually designed, uncemented femoral component for achievement of improved strain distribution and fixation to the bone, to make uncemented stems more applicable in femurs of abnormal size and shape, and to improve the joint mechanics. Here we describe the design of the implant and present the results of a prospective clinical study with at least...

To the Editor: We read with interest the article, ‘‘Systematic Review of Cemented and Uncemented Hemiarthroplasty Outcomes for Femoral Neck Fractures’’ by Ahn et al. [1], which concluded there was no significant difference between cemented and uncemented techniques for reported outcome measurements of femoral neck fractures. Respecting the highly influential status of systematic review in the h...
