[Surgical treatment of radial head fracture].

Abstract

Fractures of the radial head are often combined with ligament ruptures or subluxations creating instability of the elbow joint. Cartilage avulsions of the capitellum trapped between the fragments are a frequent observation. We advocate ORIF for displaced fractures. The posterolateral approach avoiding compression of the radial nerve may be prolonged proximally with an osteotomy of the humeral epicondyle giving full overview of the circumference of the head. It allows the harvesting of cancellous bone used as a graft to fill in articular depressed areas or metaphyseal defects. The stabilisation is achieved with thin screws of 1.5 mm diameter introduced in different planes, their head slightly sunken in the cartilage. Lately miniplates have been used in cases of neck fractures with surprisingly good functional results. The author reports about the results in 42 of 49 operated patients.
