Clinical Signs of Scaphoid Fracture
نویسنده
چکیده
This is a prospective study evaluating the efficacy of four clinical signs believed to be useful in the diagnosis of scaphoid fracture. Two hundred and fifteen consecutive patients with suspected scaphoid fracture were examined on two separate occasions to evaluate tenderness in the anatomical snuff box (ASB), tenderness over the scaphoid tubercle (ST), pain on longitudinal compression of the thumb (LC) and the range of thumb movement (TM). At the initial examination ASB, ST and LC were all 100% sensitive for detecting scaphoid fracture with specificities of 9%, 30% and 48% respectively. These clinical signs used in combination, within the first 24 hours following injury, produced 100% sensitivity and an improvement in the specificity to 74%. TM had 69% sensitivity and 66% specificity. Our results suggest that these clinical signs are inadequate indicators of scaphoid fracture when used alone and should be combined to achieve a more accurate clinical diagnosis.

Bone scintigraphy in the management of X-ray-negative potential scaphoid fractures.
One hundred and eleven patients with signs and symptoms of carpal scaphoid injury, but with no fracture visible on X-ray, underwent bone scintigraphy of the wrists. The first 42 patients were re-X-rayed 10 days after injury: bone scanning had identified all fractures confirmed on this X-ray; there were no false negative bone scans. Sixty-seven patients (60%) did not have increased focal uptake ...
متن کاملTrans-Scaphoid Perilunate Fracture-Dislocation and Isolated Perilunate Dislocations; Surgical Versus Non Surgical Treatment
Background: Trans-scaphoid perilunate fracture-dislocation and perilunate dislocations are among uncommon injuries, most commonly seen in young patients due to high energy trauma. The treatment can be achieved either surgically by open reduc tion and internal fixation or closed reduction and casting. Methods: To compare surgical versus non-operative results of treatment of trans-scaphoid pe...
متن کاملTrans-scaphoid perilunate fracture dislocation: 'notjust a scaphoid fracture'.
Rowan CH, Downing ND. BMJ Case Rep 2017. doi:10.1136/bcr-2017-221041 Description Perilunate dislocations are uncommon high-energy injuries which are missed in approximately 25% of cases on initial presentation. We present the X-rays of a 25-year-old man who fell from a height of approximately 2 metres onto an extended wrist. Plain radiographs (figure 1) show classical signs of a trans-scaphoid ...
متن کاملPilot study evaluating a clinical decision tool on suspected scaphoid fractures.
In an earlier study we have proposed a scaphoid decision-protocol in order to improve diagnostic accuracy in case of suspected scaphoid fractures. This pilot study evaluated this protocol. In this pilot study (n = 31) most cases with clinical suspicion of scaphoid fractures reached a positive test result on the combined 7 clinical tests (93.5%). Using this test combination, no scaphoid fracture...
متن کاملInter-observer agreement between 2-dimensional CT versus 3-dimensional I-Space model in the Diagnosis of Occult Scaphoid Fractures
Background: The I-Space is a radiological imaging system in which Computed Tomography (CT)-scans can be evaluated as a three dimensional hologram. The aim of this study is to analyze the value of virtual reality (I-Space) in diagnosing acute occult scaphoid fractures. Methods: A convenient cohort of 24 patients with a CT-scan from prior studies, without a scaphoid fracture on radiograph, ye...
