Summary
Diagnosing hamate fracture-dislocation requires careful review of hand radiographs, including oblique views. Three-dimensional computed tomography (3D-CT) aids in accurate diagnosis of this complex hand injury.
Area of Science:
- Orthopedic Surgery
- Trauma Care
- Radiology
Background:
- Hamate fracture-dislocation is a rare but significant hand injury.
- Accurate diagnosis can be challenging on initial radiographic assessment.
Observation:
- Two cases of hamate fracture-dislocation following trauma are presented.
- Case 1 involved a dorsal oblique hamate fracture with dorsal dislocation of the fourth metacarpal base.
- Case 2 featured a dorsal oblique hamate fracture without metacarpal dislocation.
Findings:
- Plain radiographs, including oblique views, are essential for initial suspicion.
- Three-dimensional computed tomography (3D-CT) is recommended for suspected cases to prevent diagnostic delays.
- Displaced fractures require open reduction and internal fixation.
Implications:
- Timely diagnosis and appropriate surgical intervention are critical for optimal patient outcomes.
- This injury pattern highlights the importance of thorough radiographic evaluation in hand trauma.
- 3D-CT aids in clarifying complex fracture-dislocations, improving surgical planning.
