Evolve™ Modular Metallic Radial Head Arthroplasty

  • Graham J. W. King


Radial head fractures are the most common fracture of the elbow [1]. Undisplaced fractures or small (< 33% of radial head) minimally displaced fractures (< 2 mm) can be treated with early motion with an excellent outcome in the majority of patients [2, 3]. Small displaced fractures which cause painful crepitus or limited motion are managed with fragment excision if they are too small or osteopenic to be treated with open reduction and internal fixation (ORIF) [4, 5, 6]. Larger displaced fractures are typically managed with ORIF with good outcomes in most patients [7-11]. However, comminuted fractures that have three or more parts have faired poorly with ORIF [10]. These comminuted radial head fractures are generally treated with radial head excision, with or without radial head replacement. In the setting of an associated injury to the medial collateral, lateral collateral, or interosseous ligaments, radial head excision is contraindicated due to its important role as a valgus, varus and axial stabilizer [12, 13, 14].
