Abstract

PURPOSE
Distal radius fracture is one of the most common factures, but incidence of concomitant scaphoid fracture is rare. The rarity makes diagnosing the concomitant scaphoid fracture often delayed. Thus, in this study, the authors examined the frequency of concomitant scaphoid injury in distal radius fracture and the type of distal radius fracture that is more commonly associated with simultaneous scaphoid fracture.
METHODS
We examined a total of 212 patients who had received treatment for the fracture in our institution. They were divided into two groups, isolated distal radius fracture group and distal radius fracture group with simultaneous scaphoid fracture, and their age, gender, body mass index and distal radius fracture type in accordance with AO classification were compared between the two groups.
RESULTS
Concomitant scaphoid fractures were found in 12 (5%) patients, and among them 10 cases were associated with type C distal radius fracture. Statistical comparison between the group with isolated distal radius fracture and the group with both distal radius and scaphoid fractures was made, and only comparison of distal radius fracture types showed statistical significance.
CONCLUSION
It is imperative to make timely and appropriate diagnosis of accompanying scaphoid fracture, since delay in making the diagnosis usually lead to many complications. We conclude that further diagnostic imaging such as computed tomography is necessary to make the correct diagnosis of concomitant scaphoid fracture, especially in type C distal radius fractures.

Figure

  Fig. 1. This is a simple X-ray and computed tomography (CT) scan of a 69-year-old female patient admitted after a car accident. Displacement of scaphoid was not observed in the simple X-ray (1st arrow); however, fracture in both scaphoid and radio-ulnar bone was observed in the CT scan (2nd arrow).

  Fig. 2. This is a simple X-ray and computed tomography (CT) scan of a 51 -year-old male patient admitted after a falling down injury. After observing scaphoid displacement in simple X-ray (1st arrow), the wrist bending ulnar radius deviation was further examined. The scaphoid displacement became more distinctive with further examination (2nd arrow). Fracture in both scaphoid and distal radius was observed in the CT scan that followed (3rd, 4th arrow).
