Peri-pyramidal semilunar dislocation of the carpus

Area of Science:

• Orthopedic Surgery
• Traumatology
• Anatomy

Background:

• Perilunar dislocations are uncommon wrist injuries.
• Peri-pyramidal semilunar dislocation represents an exceptionally rare subtype.
• Understanding the aetiopathogenesis is crucial for effective management.

Observation:

• The study presents a unique case of open peri-pyramidal semilunar dislocation.
• This specific injury pattern involves significant carpal bone displacement.
• The open nature of the dislocation adds complexity to the presentation.

Findings:

• The case demonstrates successful closed reduction of the dislocation.
• Immobilization with a plaster cast for six weeks was the primary treatment.
• Excellent functional and anatomical results were achieved post-treatment.

Implications:

• This case highlights that even rare dislocations can be managed effectively.
• It reinforces the importance of prompt diagnosis and appropriate reduction techniques.
• The findings contribute to the limited literature on peri-pyramidal semilunar dislocations, aiding future clinical practice.
