Trapezoid fracture is a break of the trapezoid bone of the wrist. Symptoms generally include wrist pain inline with the index finger. They are often associated with other wrist fractures or dislocations. Complications may include arthritis.
Treatment of fractures that are well aligned is by orthopedic casting for 4 to 6 weeks. Otherwise surgery is generally indicated. Outcomes appear to be generally good. Trapezoid fractures represent less than 1% of wrist bone fractures. It is the rarest broken wrist bone along with the pisiform.
