Publisher's Synopsis
This title focuses on such areas as joint replacement and shoulder and upper extremity. Shoulder arthroplasty offers significant challenges to the surgeon, especially when dealing with deformities and wear on the humerus and glenoid. Like hip and knee arthroplasty, successful shoulder arthroplasty is largely dependent on proper component alignment. Deformity and osseous wear can hinder proper prosthetic positioning and can lead to complications, such as dislocation and glenoid loosening. Computer-assisted navigation has improved component positioning in hip and knee arthroplasty. More recently, this same technology has been applied during shoulder arthroplasty with good results. Computer-assisted navigation has been particularly useful when the surgeon is attempting to correct the posterior glenoid wear (biconcavity) that is frequently observed in cases of primary osteoarthritis. During glenoid reaming, computer-assisted navigation allows for the quantified correction of glenoid version, which improves implant alignment. The video demonstrates how to use computer-assisted navigation during shoulder arthroplasty to improve implant placement.
