Mechanisms of Load Transfer between a Polyethylene Glenoid Implant and Bone: Implications for Loosening in Total Shoulder Arthroplasty
ثبت نشده
چکیده
INTRODUCTION: Loosening of glenoid components in total shoulder arthroplasty is a common clinical problem which can necessitate revision surgery. The mechanism of loosening is poorly understood and may be related to factors including implant design, component fixation techniques, and to tensile stresses at the interfaces. We are unaware of any studies that have examined the fundamental aspects of load transfer to bone for various joint loading configurations. The objective of this study was to investigate the effect of joint loading on bone strain adjacent to a polyethylene glenoid implant.

Revision of Anatomic Total Shoulder Arthroplasty to Hemiarthroplasty: Does it work?
Background: The projected increase in revision shoulder arthroplasty has increased interest in the outcomes of theseprocedures. Glenoid component removal and conversion to a hemiarthroplasty (HA) is an option for aseptic glenoidloosening after anatomic total shoulder arthroplasty (aTSA).Methods: We identified patients who had undergone revision shoulder arthroplasty over a 15-...
متن کاملPolyethylene Wear in Anatomic and Reversed Shoulder Prostheses
INTRODUCTION: Polyethylene wear is a recurrent problem in joint arthroplasty. In addition to permanent deformation or complete destruction of the component, small debris particles are also associated to inflammation reaction of the surrounding bone, eventually leading to the failure of the bound between the implant and the host bone, and implant loosening. In anatomic total shoulder arthroplast...
متن کاملMid-term results of a metal-backed glenoid component in total shoulder replacement.
Total shoulder replacement is a successful procedure for degenerative or some inflammatory diseases of the shoulder. However, fixation of the glenoid seems to be the main weakness with a high rate of loosening. The results using all-polyethylene components have been better than those using metal-backed components. We describe our experience with 35 consecutive total shoulder replacements using ...
متن کاملObservations on retrieved glenoid components from total shoulder arthroplasty.
HYPOTHESIS Polyethylene components retrieved at revision of total knee and hip replacements have been analyzed to study the effect of design, patient, and surgical factors on initial implant performance, but few studies have reported similar types of findings in retrieved glenoids. MATERIALS AND METHODS From 1979 to 2006, 78 glenoid components were retrieved from revision surgery in 73 patien...
متن کاملUse of a caged, bone ingrowth, glenoid implant in anatomic total shoulder arthroplasty technique and early results.
Shoulder arthroplasty represents one of the fastest growing orthopaedic procedures in the USA. In comparison to hemiarthroplasty, total shoulder arthroplasty has higher patient satisfaction and lower revision rates. Aseptic glenoid loosening remains a concern for longevity of total shoulder arthroplasties. Cement fixation on the glenoid side represents the primary and only mode of fixation in t...
