Modularity of the femoral component in total hip arthroplasty.
Modular femoral components have been developed to aid in recreating native femoral version, limb length, and offset in total hip arthroplasty. Use of modular implants results in cost savings, as well. Inventory can be reduced while allowing intraoperative flexibility and options. With modular implants, the femoral prosthesis can be built in situ, which is helpful in minimizing incision length a...
متن کاملFemoral Neck Modularity in Tha: Not a Bridge Too Far?
While modular femoral neck systems have been successfully employed for a variety of patient skeletal pathology, they are not without clinical concerns. Their structural compromise at metal-metal interconnections due to cyclic microdisplacements, component disassociation in vivo, and increased potential for metallic wear debris generation and corrosion have all been reported along with tissue re...
متن کاملDesigning an Optimized Novel Femoral Stem
BACKGROUND After total hip arthroplasty, there would be some problems for the patients. Implant loosening is one of the significant problems which results in thigh pain and even revision surgery. Difference between Young's modulus of bone-metal is the cause of stress shielding, atrophy, and subsequent implant loosening. MATERIALS AND METHODS In this paper, femoral stem stiffness is reduced by...
متن کاملFracture of Revision Modular Femoral Stem
The number of revision total hip arthroplasties is predicted to more than double in USA over the next 25 years from an estimated 40800 in 2005 to approximately 96700 in 2030 [1]. Modular femoral stems offer the advantage of adjustment and restoration of joint kinematics including leg length, femoral version and offset, regardless of the exact position of the distal part of the stem [2]. Disadva...
متن کاملDoes Early Micromotion of Femoral Stem
Roentgen stereophotogrammetry was used to measure the migration of the centre of the femoral head in 84 cemented Lubinus SP I hip arthroplasties (58 primary operations, 26 revisions). Four to seven years later, seven femoral components had been revised because of painful loosening. These implants showed greater subsidence, medial migration and posterior migration during the first two postoperat...
