Feb 26, 2025 · Radial Head Fractures are common intra-articular elbow fractures that can be associated with an episode of elbow instability, a mechanical block to elbow motion, an injury to the distal radioulnar joint and/or to the interosseous membrane (Essex-Lopresti). Diagnosis can be made with plain radiographs of the elbow.

Radial head fractures range in severity from occult and nondisplaced fractures to fractures with severe displacement and comminution. The principal goal of the Mason classification – like many fracture classifications – is to guide treatment according to the pattern of the injury.

Aug 13, 2024 · The Mason classification ( sometimes known as Mason-Johnston classification) is used to classify radial head fractures and is useful when assessing further treatment options 1,2. Classification. type I: non-displaced radial head fractures (or small marginal fractures), also known as a "chisel" fracture

Mar 19, 2021 · Nonoperatively treated adults with an isolated Mason type 2 radial head fracture have similar functional results after 1 year compared with operatively treated patients. In addition, complication rates were low for both operative and nonoperative treatment.

Mason type I fractures are the most common fractures of the radial head. The fractures have a benign character and often result in good, pain-free function. Nevertheless, up to 20% of patients with a Mason type I fracture report loss of extension and residual pain.

Mason classification is used to classify radial head fractures. type I: undisplaced fracture (<2 mm) type II: displaced marginal sector of the radial head or displaced neck fracture (>2 mm) type III: comminuted radial head fracture or completely displaced neck fracture; type IV: elbow dislocation with radial head fracture

Purpose: There is no consensus as to the best treatment of Mason type II fractures without concomitant elbow fractures or dislocation. The aim of this systematic review was to compare the results of operative and nonoperative treatment of these injuries.
