Dual extensor tendon entrapment in Galeazzi fracture-dislocation: a case report

Area of Science:

• Orthopedic Surgery
• Traumatology
• Anatomy

Background:

• Galeazzi fracture-dislocation is a complex injury involving the distal radius and ulna.
• Blocked reduction of the distal radio-ulnar joint can complicate fracture management.
• Understanding the anatomical structures involved is crucial for successful treatment.

Observation:

• A rare case of Galeazzi fracture-dislocation presented with irreducible distal radio-ulnar joint.
• Intraoperative findings revealed displacement of the extensor carpi ulnaris and extensor digiti minimi tendons.
• These tendons were positioned on either side of the ulnar head, obstructing reduction.

Findings:

• The primary finding was tendon interposition blocking the reduction of the distal radio-ulnar joint.
• Successful reduction was achieved only after the displaced tendons were repositioned.
• This highlights a specific mechanism of blocked reduction in this injury pattern.

Implications:

• This case emphasizes the importance of careful intraoperative assessment for tendon displacement in Galeazzi fractures.
• Accurate anatomical knowledge aids in diagnosing and managing complex fracture-dislocations.
• Recognizing and addressing tendon interposition can prevent complications and improve patient outcomes.
