Uncommon Trapezoid Fractures Cause Significant Wrist Discomfort
Trapezoid fractures, though uncommon, cause significant discomfort and reduced wrist mobility. This type of fracture affects the trapezoid bone, the least frequently injured carpal bone, which forms a stable joint with the second metacarpal base.
Trapezoid fractures result from axial force applied to the second metacarpal base. This injury causes pain at the base of the second metacarpal and swelling in the wrist, along with decreased range of motion. The trapezoid bone, shaped like a wedge with a broader dorsal side, is well-protected due to its structure.
Treatment options for trapezoid fractures are not yet standardized due to their rarity. Surgeons may choose to remove a small fragment of the bone or perform open reduction and internal fixation. Notably, the trapezoid bone lacks internal anastamoses but has multiple blood supply sources, ensuring adequate nourishment.
Trapezoid fractures, though uncommon, cause significant wrist discomfort and reduced mobility. Treatment options are not yet established due to their rarity, but may involve bone fragment removal or open reduction and internal fixation. Despite its sheltered position, the trapezoid bone's unique structure and blood supply make it susceptible to specific injuries.
