Stability of Reverse Shoulder Humeral Implants in a Proximal Humerus Bone Loss Model
ثبت نشده
چکیده
The treatment of proximal humeral bone loss with its associated pain and loss of function continues to be a challenge for the orthopaedic surgeon. Current options for this condition include hemiarthroplasty or total shoulder arthroplasty with the addition of bone grafting. Unfortunately, due to residual instability, these options have not given the desired results. Reverse shoulder arthroplasty is becoming a viable option for these difficult cases, although it has yet to be tested biomechanically in a proximal humeral bone loss model. The purpose of this study was to determine the effect of proximal humeral bone loss on the fixation of reverse shoulder humeral implants.

Tension wiring to increase stability of conventional plating for proximal humeral fractures: An alternative to a locking plate
Fixation of comminuted or osteoporotic fractures in the proximal humerus is a challenge for orthopedic surgeons. In the past two decades, locking plates have been used for proximal humeral fracture fixation. However, complications such as loss of reduction have been reported, and the implants are not always available in some regions. Therefore, we describe an alternative procedure involving fix...
متن کاملLocking plate fixation for proximal humerus fractures.
Locking plates are increasingly used to surgically treat proximal humerus fractures. Knowledge of the bone quality of the proximal humerus is important. Studies have shown the medial and dorsal aspects of the proximal humeral head to have the highest bone strength, and this should be exploited by fixation techniques, particularly in elderly patients with osteoporosis. The goals of surgery for p...
متن کاملReverse Prosthesis for Proximal Humerus Fracture, Technique and Results
The reverse prosthesis has become a treatment of choice for glenohumeral osteoarthritis in a cuff-deficient shoulder. It allows restoration of mobility despite the loss of rotator cuff function. Hemiarthroplasty, the historical standard of care for proximal humeral fractures requiring replacement, fails most commonly because of tuberosity nonunion. Therefore, in the face of poor bone quality, t...
متن کاملReverse Shoulder Arthroplasty for the Treatment of 3 and 4- Part Fractures of the Humeral Head in the Elderly
BACKGROUND Proximal humeral fractures in elderly patients present with severe comminution and osteoporotic bone quality. Reverse shoulder arthroplasty has lately been proven beneficial in treating patients with complex proximal humeral fractures. The above technique is recommended and has better results in elderly than in younger individuals. METHODS We performed a literature search in the da...
متن کاملTotal Shoulder Arthroplasty
Shoulder arthroplasty has been the subject of marked advances over the last few years. Modern implants provide a wide range of options, including resurfacing of the humeral head, anatomic hemiarthroplasty, total shoulder arthroplasty, reverse shoulder arthroplasty and trauma-specific implants for fractures and nonunions. Most humeral components achieve successful long-term fixation without bone...
