Technical tips for fixation of proximal humeral fractures in elderly patients.

Despite the application of modern locking plate technology, complications remain common after fixation of proximal humeral fractures in elderly patients. Varus deformity and intra-articular hardware are most often responsible; fortunately, both of these complications can be avoided. Recent advances in imaging, reduction techniques, fixation methods, and postoperative care have made surgical outcomes more reliable. Particular attention should be directed to obtaining high-quality fluoroscopic images, avoiding varus reductions, supporting the osteoporotic humeral head, using appropriate screw length, using tension band sutures liberally, and protecting the construct postoperatively. With these methods, many proximal humeral fractures in patients older than 75 years can be reliably fixed.
