Abstract

We described an unusual case of a 16-year-old Taekwondo athlete who injured the left wrist when she compete with other athlete. She described a mechanism of axial loading, with the wrist in radial deviation. This unusual combined lunate and triquetrum fracture was not associated with the perilunar dislocation. We present this case with a review of the literature. In this case, internal fixation and early range of motion result in a good functional outcome.
Key words: Lunate, Triquetrum, Fracture, Taekwondo

Fig. 1

Initial anteroposterior and lateral images demonstrate displaced lunate (arrow head) and triquetral (arrow) fracture, but, there is no clear evidence of dislocation.

Fig. 2

Computed tomographic scans of the left wrist demonstrate the displaced lunate (arrow head) and triquetral (arrow) fracture. The lunate has palmar pole fracture that extended to the palmar third of the articular surface on the capitate side. The triquetrum has frontal simple fracture (sagittal, axial view).

Fig. 3

Anteroposterior and lateral radiographs show the anatomical reduction and internal fixation obtained with microscrews (1.2 mm×2) in the lunate and Acutrak screw (15.0 mm) in the triquetrum.

Fig. 4

Final anteroposterior and lateral radiographs after Acutrak screw removal. At 9 months, union of both the lunate and the triquetrum is present.
