Summary
Trapezial ridge fractures from dorsiflexed wrist falls present with thenar pain. Type I fractures healed with immobilization, but Type II avulsion fractures did not, indicating different treatment needs for trapezial ridge injuries.
Area of Science:
- Orthopedic Surgery
- Radiology
- Hand Surgery
Background:
- Trapezial ridge fractures are uncommon injuries.
- These fractures result from falls onto a dorsiflexed wrist.
- Symptoms include thenar eminence pain and tenderness.
Observation:
- Three patients with trapezial ridge fractures were reviewed.
- Fractures occurred on the palmar aspect of the trapezium.
- Specific radiologic views (carpal tunnel view) were crucial for diagnosis.
Findings:
- Type I fractures at the base of the trapezial ridge demonstrated healing with immobilization.
- Type II avulsion fractures of the trapezial ridge tip did not achieve union with immobilization alone.
- This suggests distinct prognoses and treatment considerations based on fracture type.
Implications:
- Accurate diagnosis of trapezial ridge fractures requires specific radiographic techniques.
- Immobilization may be sufficient for base fractures (Type I).
- Avulsion fractures (Type II) may require alternative or additional interventions beyond immobilization for successful healing.
