Editing Trapezoid bone (section)

==Clinical Significance==

Isolated fractures of the trapezoid are rare, representing 0.4% of the total, thus being the least common of all carpal fractures. This is due to the bone being in a fairly protected position. Distally, it forms a stable, relatively immobile joint with the second metacarpal, radially and proximally it forms strong ligaments with the trapezium and the capitate ulnarly, scaphoid respectively.

However, injury can occur through axial force applied to the second metacarpal base. Subluxations, such as ones caused by delivering a blow, are not uncommon. Direct trauma to the bone can also cause fracture.

Due to its rarity, standard treatment has not been established. A wide range of treatments are possible, including rest, surgery and casting.<ref>{{cite journal | pmc = 2584218 | pmid=18780025 | doi=10.1007/s11552-008-9100-8 | volume=3 | title=Rare isolated trapezoid fracture: a case report | year=2008 | journal=Hand (N Y) | pages=372–4 | last1 = Sadowski | first1 = RM | last2 = Montilla | first2 = RD| issue=4 }}</ref>
