example 1

[0095]A 62 year old woman presented with progressive, debilitating shoulder pain from osteoarthritis, which she had experienced for approximately 15 years. She had constant pain (rated 9 / 10) and difficulty washing her hair, fastening her bra, lifting a cup of coffee, and performing other daily activities. The preoperative radiographs and CT scan showed severe shoulder arthritis and glenoid bone loss that would preclude the use of a keeled or pegged glenoid implant. There was concern that a hemiarthroplasty procedure (replacement of the humeral ball, which would leave the arthritic glenoid socket bare) would not relieve the patient's pain.

[0096]A total shoulder replacement using an inset glenoid implant of the invention and a standard humeral implant was performed. The smaller size and circumferential fixation of the inset glenoid implant allowed safe placement of the prosthesis within the confines of the patient's deficient glenoid cavity.

[0097]The deficient glenoid vault was not fr...

example 2

[0099]An 81 year old woman presented with severe shoulder pain and stiffness. She had severe shoulder arthritis with medial wear causing glenoid bone loss. Her own assessment of shoulder function was 25% of normal (American Shoulder and Elbow Society validated outcome score [ASES score] was 25).

[0100]A total shoulder replacement using an inset glenoid implant prosthesis was performed. Two months after her surgery, the patient had no pain and exhibited improved function. Her own assessment of shoulder function was 70% of normal (American Shoulder and Elbow Society validated outcome score [ASES score] was 70).

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This is a continuation application of U.S. patent application Ser. No. 11 / 066,978 filed on Feb. 25, 2005, the entirety of which is hereby incorporated by reference herein and made a part of the present specification.FIELD OF THE INVENTION[0002]The present invention relates to the field of glenoid surface replacement.BACKGROUND OF THE INVENTION[0003]The invention provides a glenoid shoulder implant, a humeral implant, and devices for preparing the glenoid and humeral head for joint replacement.[0004]Shoulder replacement surgery is currently used to treat patients suffering from disabling pain due to worn or damaged shoulder joints, which can be caused by, e.g., arthritis or injury. The humeral implants currently in use are typically made from metal, and the implants are affixed to the bone using bone cement (e.g., polymethylmethacrylate) or by press fitting the implant into the bone using a roughened outer surface coating on the metal for ...
