Scaphoid Fractures are the most common carpal bone fracture, often occurring after a fall onto an outstretched hand. Diagnosis can generally be made by dedicated radiographs but CT or MRI may be needed for confirmation.
Scaphoid Fracture Nonunion occur in 5-25% of scaphoid fractures following treatment, and are more common in older patients, smokers, and when there is a delay in the initial treatment of the fracture. Diagnosis is made with a combination of radiographs and a CT scan. MRI studies may be used to assess for avascular necrosis.
ACuTE SCAPHOID FRACTuRES Epidemiology The scaphoid is the most commonly fractured carpal bone. It accounts for 60% of carpal fractures, 11% of hand frac-tures, and 2% of all fractures. Estimated annual incidence of scaphoid fractures is somewhere between 29 and 43 fractures per 100,000 persons.1,12,13 Most commonly, it
In cases of suspected scaphoid fracture where the initial radiographs are negative, a supplementary MRI, or alternatively CT, should be carried out within three to five days.Fracture classification, assessment of dislocation as well as evaluation of fracture healing is best done on CT with reconstructions in the coronal and sagittal planes ...
Fracture proximal to the perforating vessels on the dorsora-dial surface of the scaphoid can cause significant bone ischemia of the proximal pole.
A scaphoid (navicular) fracture is a break in one of the small bones (carpal bones) of the wrist. This type of fracture occurs most often after a fall onto an outstretched hand. Symptoms of a scaphoid fracture typically include swelling and pain in the wrist just below the base of the thumb.
This topic will review the diagnosis and nonoperative management of scaphoid (navicular) fractures in adults. Discussions of wrist anatomy, biomechanics, and other wrist-related injuries in adults and children are provided separately.
A scaphoid fracture is a type of wrist fracture that occurs most commonly from a fall on the outstretched hand. You may not know you have one until weeks later.
He experiences immediate-onset, severe left wrist pain and inability to flex or extend his wrist. On exam, he has point tenderness dorsally over the anatomic snuffbox. A radiograph of his left wrist demonstrates a fracture of the proximal pole of the scaphoid.
Initial radiographs in patients suspected of having a scaphoid fracture should include anteroposterior, lateral, oblique, and scaphoid wrist views. Magnetic resonance imaging or...
