Imaging of Hamate Bone Fractures in Conventional X-Rays and High-Resolution Computed Tomography

Abstract

Fractures of the body and hook of the hamate cannot always be detected with certainty in the conventional X-ray image, even if different projectional planes are used. The HR-CT is the imaging procedure of choice for further clarification, and an axial or sagittal plane should be selected.

Lodox/Statscan facilitates the early detection of commonly overlooked extracranial injuries in patients with traumatic brain injury

“…However, there were no complications in these patients related to the delayed diagnosis of distal bones fractures. Besides, the reported sensitivity of conventional X-rays for the detection of wrist fracture was 72.2% [29]. Some retrospective studies also suggested that 10-33% of patients with a proven distal bone fracture had no fracture visible on the conventional X-rays [30,31].…”

Carpometacarpal fracture dislocation of the fourth and fifth finger: mid-term results of 15 patients

“…In the present study, oblique radiographs with the hand pronated 30° were routinely used for diagnosis. Although Andresen et al [13] and Kaneko et al [14] demonstrated that threedimension computed tomography (CT) findings proved to be superior to other radiographic imaging, CT imaging is not routinely used in our clinic due to the high cost and radiation exposure.…”

Minimal Invasive Fixation of Hamate Hook Fractures Through a Dorsal Percutaneous Approach Using a Mini Compression Screw: An Experimental Feasibility Study

“…CT was most accurate at detecting the fracture line and hook position [5,24,25], and it allowed us to determine the exact size of the fragment. Due to the distal thread length of the mini-screw used in this study, our technique is limited to a fragment size and radioulnar diameter of the hook of more than 5 mm.…”

“…Isolated fractures of the hamate hook appear to occur more frequently than previously reported, which could be attributed to the increasing popularity of sports activities, such as golf, tennis, baseball, and hockey, more careful assessment of wrist injuries, and improved radiographic imaging [1][2][3][4][5]. Hook fractures are caused by direct or indirect trauma or a combination of both.…”
