Micromotion of cemented and uncemented femoral components

Cemented versus uncemented femoral components in the ring hip prosthesis.

A prospective, randomised and independently assessed trial of the Ring UPM total hip replacement showed that the quality of the early result was better if the femoral prosthesis was cemented than if it was not. More patients with cemented prostheses were painfree at four months (58% cemented:42% uncemented) and at one year (63% cemented:50% uncemented), but at two years pain relief was equal in...

Uncemented custom femoral components in hip arthroplasty

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...

Effect of simulated early weight bearing on micromotion and pullout strength of uncemented distal femoral stems.

The effect of simulated early weight bearing on both micromotion and pullout strength of uncemented distal femoral stems was evaluated in this study. The effect of stem endosteal contact and bone quality on implant pullout strength was also analyzed. A randomized matched-pair study was performed using 8 bilateral pairs of fresh human cadaveric femoral specimens. Each specimen pair was dual-ener...

Mid-term results of previously cemented hip arthroplasties revised with uncemented modular femoral components: a retrospective study

BACKGROUND We evaluated the mid-term results of previously cemented hip arthroplasties revised with uncemented modular femoral components. METHODS The study included 40 patients (36 females (90 %) and 4 males (10 %), mean age 67.6 years, range 39-87 years) who underwent revision of a previously cemented hip prosthesis with an uncemented modular femoral stem between 2005 and 2009. The indicati...
