Follow-up radiographs showed <30[degrees] angulation and 1 mm of translation of the radial head
BA= brachial artery, BRA= brachioradial artery, MN= median artery, RH= radial head
of splitting MN, MH=medial head of splitting MN.
The radial head
fracture is the most common elbow fracture in adults.
Children with nondisplaced radial head
or radial neck fractures can be treated with a posterior splint and ice.
More recent case series have included floating elbow variants including ipsilateral diaphyseal humeral fracture with proximal ulna fracture, and proximal radioulnar joint disruption (Monteggia fracture); ipsilateral diaphyseal humeral fracture, elbow dislocation, and diaphyseal ulna and radius fracture; and distal humerus fractures with intraarticular fractures of the olecranon or radial head
In a literature search of "elbow locking," there was only a single case report of unrecognized osteochondral radial head
fracture reported as an unusual cause of locking.
The radial head
attaches firmly to the entire medial border and caudal aspect of the radius, enveloped by a tough septum of the antebrachial fascia.
Computed tomography (CT) reveals a normal radial head
To our knowledge, only one study has been addressed using radial head
prosthesis in conjunction with the osteocutaneous fibular flap to restore elbow stability and range of motion .
Congenital dislocation of the radial head
is a rare entity (incidence, 0.16%).

, the olecranon, and the coronoid," The Journal of Bone & Joint Surgery, vol.
Combined radial head
fractures and interosseous ligament ruptures often result in severe disability, causing proximal migration of the radius, chronic wrist pain, reduced grip strength, and loss of range of motion.
