Adult Bado type I Monteggia fracture dislocation: A case report

Area of Science:

• Orthopedic Surgery
• Trauma Care
• Radiology

Background:

• Monteggia fracture-dislocations involve ulnar shaft fractures with radial head dislocation.
• Bado classification categorizes these injuries into four types based on radial head displacement.
• Adult Bado type I (anterior radial head dislocation) Monteggia fractures are exceptionally rare.

Observation:

• A 55-year-old male sustained a Bado type I Monteggia fracture-dislocation from direct posterior ulnar trauma.
• The patient presented with an ulnar shaft fracture and anterior radial head dislocation.
• Diagnosis can be challenging due to subtle radial dislocation often masked by the ulnar fracture.

Findings:

• The patient underwent open reduction and internal fixation (ORIF) five days post-injury.
• At discharge, he achieved 75% active elbow flexion and extension.
• This case highlights a unique mechanism and treatment approach for a rare fracture subtype.

Implications:

• Early and accurate diagnosis of Bado type I Monteggia fractures is vital.
• Timely intervention is essential for optimal patient outcomes, including range of motion and arm function.
• This report contributes to the limited literature, aiding clinicians in recognizing and managing these complex injuries.
