“…In Klein’s study [17], ultrasound was found to be with 91.1% sensitivity and 25% specificity. However, a study showed that the positive rate of MTP drawer test in grade 1 MTP instability was found in 34.4% of joints with normal US finding [22]. In our study, the sensitivity and specificity of US are 93 and 33%.…”

BackgroundPlantar plate tears could be the reason of forefoot pain, affecting foot function. Magnetic resonance imaging (MRI) and ultrasound (US) were commonly used for the diagnosis of plantar plate tears. The decision of whether to use MRI or US carried some controversy. Our study aimed to find out the diagnostic accuracy of MRI versus US for plantar plate tears.MethodsThe database of the Cochrane Central Register of Controlled Trials (CENTRAL), PubMed, EMBASE, and relative orthopedic meetings until May 2016 were searched. Studies involved in the diagnostic detection of MRI or ultrasound for plantar plate tears with surgical criteria as the reference test were included. Data was analyzed by meta-analysis. We compared sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, and summary receiver operating characteristic (sROC) plot of both MRI and US.ResultsSeven studies involving 246 plantar plate tears were included. The MRI showed more diagnostic accuracy than US for the detection of plantar plate tears. The sensitivity, specificity, positive likelihood ratio, and negative likelihood ratio of MRI were 95%, 54%, 2.08, and 0.08, respectively, while the same values for US were 93%, 33%, 1.20, and 0.35, respectively. And the sROC showed more superior diagnostic accuracy than the US.ConclusionThe current result suggests that MRI has better accuracy than US for detection of plantar plate tears.

“…On physical exam there may be ecchymosis at the volar MTP joint and focal pain. A drawer test, where the MTP is stressed dorsally, is positive when there is excessive dorsal translation of the proximal phalanx and supports the diagnosis of turf toe [ 53 , 54 , 56 ].…”

Musculoskeletal ultrasound: athletic injuries of the lower extremity

et al. 2018

View full text Add to dashboard Cite

Athletic injuries of the lower extremities are commonly encountered in clinical practice. While some pathology can be diagnosed on physical exam, others are a clinical dilemma with nonspecific symptomatology. In these situations, ultrasound imaging can be utilized as an exceptional diagnostic tool, offering unique advantages over other imaging modalities. This article will review the imaging characteristics of commonly encountered athletic injuries of the lower extremity.

“…4,5,8,12 The load through the second MTP PP constitutes 25% of the entire load transmitted through the forefoot during weight-bearing, placing it at greatest risk for degeneration and complicating the tear. 8,16,17 Although PP tears also occur at the third and fourth MTP joints, they are less common when compared with the second MTP joint and are uncommonly symptomatic. 16 PP tears are typically chronic degenerative tears in middle-aged and older women, often accompanied by hallux valgus.…”

Lesser (or central) metatarsalgia is defined as pain in the forefoot under or around the lesser metatarsals and their respective metatarsophalangeal joints. Two common causes of central metatarsalgia are Morton's neuroma (MN) and plantar plate (PP) injury. Because both clinical and imaging features overlap, establishing the correct differential diagnosis may be challenging. Imaging has a pivotal role in the detection and characterization of metatarsalgia. Different radiologic modalities are available to assess the common causes of forefoot pain, so the strengths and weakness of these imaging tools should be kept in mind. It is crucial to be aware of the pitfalls that can be encountered in daily clinical practice when dealing with these disorders. This review describes two main causes of lesser metatarsalgia, MN and PP injury, and their differential diagnoses.
