Transscaphoid perilunate dislocation--a tale of two carpals?

Area of Science:

• Orthopedic Surgery
• Trauma Care
• Radiology

Background:

• Perilunate dislocation with transscaphoid fracture is a rare but severe wrist injury.
• Hyperextension injuries are a common mechanism for this type of trauma.
• Early recognition and management are critical for optimal patient outcomes.

Observation:

• Two cases of perilunate dislocation with transscaphoid fractures were presented within a short period.
• Both injuries resulted from significant hyperextension mechanisms.
• Initial management occurred in an accident and emergency department.

Findings:

• Both patients required open reduction and internal fixation under general anesthesia.
• Post-operative care included plaster cast immobilization and close clinical follow-up.
• The study emphasizes the importance of recognizing radiological signs of this injury.

Implications:

• Junior emergency staff need to be aware of the presentation and diagnostic clues for this injury.
• Timely surgical intervention is essential to prevent long-term complications.
• Understanding the biomechanics of hyperextension injuries aids in diagnosis and treatment planning.
