Primäre posttraumatische Radiuskopfprothetik

Abstract

Radial head fractures are common injuries in elbow trauma. Non-displaced fractures are best treated conservatively. Simple but displaced fractures require anatomic reduction and fixation, typically using screws. The treatment course for complex fractures with multiple fragments is still being debated, as results are less predictable. Radial head resection is not advised if concomitant injuries of the coronoid process or the collateral ligaments with instability are present. Favorable outcomes following open reduction and fixation using plates were reported recently. However, complication rates are very high. Radial head replacement is a valuable tool in treating complex fractures of the radial head with predominantly good and excellent results. Patients who suffer radial head fractures are typically of a younger age, resulting in high functional demands. Certainly, unspecific and specific complications related to radial head arthroplasty were reported in up to 40 % of cases in an acute fracture setting. This article highlights common complications in radial head arthroplasty and aims to present strategies to avoid them.

Acute Joint Blockage due to Abrasion-Related Dislocation of a Silastic Radial Head Prosthesis: A Histological Examination after 14 Years of Durability

“…Many studies and case reports after implantation of a silastic prosthesis describe foreign body reactions with accompanying synovitis and poor functional results [ 7 , 8 ]. Inflammatory arthritis, reactive synovitis, and dislocation of the prosthesis after radial head replacement with a silastic head prosthesis are also described in the literature [ 10 , 11 , 13 ]. After five years, an average of a material failure is often described [ 8 ].…”

“…The presented silastic radial head prosthesis (Wright Medical Technology Inc.) was taken off the market, because of the side effects described. In radial head prosthetics, the choice of prostheses material should be selected carefully and in a patient-specific manner in view of the results presented [ 13 , 16 , 17 ].…”
