Isolated dislocation of the trapezoid

Area of Science:

• Orthopedic Surgery
• Trauma Care
• Radiology

Background:

• Trapezoid dislocations are rare wrist injuries.
• High-energy trauma, such as motor vehicle accidents, can cause these injuries.
• Diagnosis can be challenging on initial radiographic evaluation.

Observation:

• A case of isolated trapezoid dislocation resulting from a high-speed motor vehicle injury is presented.
• The injury was initially not apparent on standard radiographs.
• Surgical intervention was necessary for reduction and fixation.

Findings:

• Isolated trapezoid dislocations are frequently overlooked in standard radiographic assessments.
• Open reduction and internal fixation are the standard management for these injuries.
• Prompt surgical treatment is crucial for optimal outcomes.

Implications:

• Radiologists and orthopedic surgeons should maintain a high index of suspicion for trapezoid dislocations in high-energy wrist trauma.
• Advanced imaging may be necessary for definitive diagnosis.
• Surgical management ensures joint stability and function restoration.
