BACKGROUND
The standard diagnostic work-up for hand and wrist fractures consists of history taking, physical examination and imaging if needed, but the supporting evidence for this work-up is limited. The purpose of this study was to systematically examine the diagnostic accuracy of tests for hand and wrist fractures.
METHODS
A systematic search for relevant studies was performed. Methodological quality was assessed and sensitivity (Se), specificity (Sp), accuracy, positive predictive value (PPV) and negative predictive value (NPV) were extracted from the eligible studies.
RESULTS
Of the 35 eligible studies, two described the diagnostic accuracy of history taking for hand and wrist fractures. Physical examination with or without radiological examination for diagnosing scaphoid fractures (five studies) showed Se, Sp, accuracy, PPV and NPV ranging from 15 to 100%, 13-98%, 55-73%, 14-73% and 75-100%, respectively. Physical examination with radiological examination for diagnosing other carpal bone fractures (one study) showed a Se of 100%, with the exception of the triquetrum (75%). Physical examination for diagnosing phalangeal and metacarpal fractures (one study) showed Se, Sp, accuracy, PPV and NPV ranging from 26 to 55%, 13-89%, 45-76%, 41-77% and 63-75%, respectively. Imaging modalities of scaphoid fractures showed predominantly low values for PPV and the highest values for Sp and NPV (24 studies). Magnetic Resonance Imaging (MRI), Computed Tomography (CT), Ultrasonography (US) and Bone Scintigraphy (BS) were comparable in diagnostic accuracy for diagnosing a scaphoid fracture, with an accuracy ranging from 85 to 100%, 79-100%, 49-100% and 86-97%, respectively. Imaging for metacarpal and finger fractures showed Se, Sp, accuracy, PPV and NPV ranging from 73 to 100%, 78-100%, 70-100%, 79-100% and 70-100%, respectively.
CONCLUSIONS
Only two studies were found on the diagnostic accuracy of history taking for hand and wrist fractures in the current review. Physical examination was of moderate use for diagnosing a scaphoid fracture and of limited use for diagnosing phalangeal, metacarpal and remaining carpal fractures. MRI, CT and BS were found to be moderately accurate for the definitive diagnosis of clinically suspected carpal fractures.

Meta-Analysis
BACKGROUNDS
Hand fractures are the second most common upper-extremity fractures. The standard X-ray has shortcomings, such as exposure to radiation. Ultrasound has been reported as an alternative method of detecting hand fractures. In this study, we used meta-analysis to assess the diagnostic value of ultrasound for hand fractures.
METHODS
Web of Science, PubMed, Embase, and Cochrane Library databases were searched for relative citations up to June 2019. The pooled sensitivity, specificity, positive likelihood ratio (PLR), negative likelihood ratio (NLR), diagnostic odds ratio (DOR), area under the summary receiver operating characteristic curve (AUC), and summary receiver operating characteristic (SROC) curve were estimated.
RESULTS
Seven studies including 842 participants (845 examined hands) met our inclusion criteria. The pooled sensitivity, specificity, PLR, and NLR of ultrasound for detecting hand fractures were 91%, 96%, 20.66, and 0.09, respectively. The pooled DOR was 231.17, indicating a very powerful diagnostic ability of ultrasound. Meta-regression showed that there was no heterogeneity with respect to age, cut-off, the performer of the ultrasound, and the types of hand fractures.
CONCLUSIONS
Our results showed that ultrasound had an excellent diagnostic value for hand fractures. In clinic, we proposed using ultrasound as a first-line and radiation-free modality in detecting hand fractures, including phalanx and metacarpal fractures.
