Abstract

Trapezoid bone fracture is the least common fracture owing to the fact that it is strictly bounded to scaphoid, capitate and the base of the second metacarpal. Isolated fractures are rarely seen and usually related to the high energy trauma. It is conservatively treated without dislocation. Triquetrum fractures are the second least common fractures among carpal bones. The body fractures are usually caused by a fall onto an open flexed hand. Non-displaced fractures can be treated conservatively. Our aim is to remind those rare fractures of the carpal bones that accompany the wrist trauma, which can require additional radiological studies.

Highlights

Trapezoid bone fracture is the least common fracture owing to the fact that it is strictly bounded to scaphoid, capitate and the base of the second metacarpal
The swelling and persisting pain above this region must remind us of non-displaced fractures
Trapezoid shape is like a keystone and the trapezoid bone; dorsal side, according palmar surface is twice as large

Summary

Introduction

Trapezoid bone fracture is the least common fracture owing to the fact that it is strictly bounded to scaphoid, capitate and the base of the second metacarpal. Triquetrum fractures are the second least common fractures among carpal bones [1]-[3]. The trapezoid bone is located in the 2nd metacarpal, trapezium, capitate and scaphoid bones and is firmly connected to them, without any possibility of movement [4]. Isolated fractured are rarely seen and the diagnosis may be missing. In the presence of doubt computerized tomography examination should be performed.
