Perched Anteromedial Radial Head Dislocation

Area of Science:

• Orthopedic Surgery
• Traumatology
• Radiology

Background:

• Radial head dislocations are common elbow injuries.
• Perched radial head dislocations are rare, with anteromedial variants undocumented.
• This study addresses a unique case of perched anteromedial radial head dislocation.

Observation:

• A patient presented with an isolated radial head dislocation.
• The dislocation was perched specifically on the coronoid process.
• Radiographic images confirmed the rare injury pattern without associated coronoid fracture or complete elbow dislocation.

Findings:

• The case represents the first reported instance of perched anteromedial radial head dislocation.
• Successful closed reduction was achieved, restoring full range of motion and function.
• This contrasts with previously reported literature, which lacks documentation of this specific injury or its non-operative management.

Implications:

• Closed reduction of such injuries can be challenging, even under anesthesia.
• Surgical settings should allow for conversion to open reduction if closed methods fail.
• This case expands the understanding of radial head dislocation injury patterns and treatment outcomes.
