Dec 10, 2021 · Fovea alta is a radiographic sign that refers to an abnormally superior position of the fovea capitis femoris in relation to the acetabular socket. Fovea alta is significantly associated with acetabular dysplasia and can be used as an indicator or diagnostic marker for the condition 1-3, otherwise, it is not associated with coxa valga.

Nov 23, 2012 · Fovea alta shows promise as a strong MRI marker of DDH. Developmental dysplasia of the hip (DDH) can vary greatly in morphologic features, ranging from a mildly shallow acetabulum to a completely dislocated high-riding hip.

The delta angle (Figure 3) measures the position of the fovea capitis. “Fovea alta” is the abnormal superior position of the fovea capitis and is frequently seen in the adult dysplastic hip.

abnormal superior position of the fovea ca-pitis, the so-called fovea alta, is a potential additional radiographic diagnostic marker of adult hip imaging studies, including absence of a well-cendysplasia. They also suggested that fovea alta, assessed by measurement of the delta angle, may be a predisposing factor

Fovea Alta Another MRI measurement associated with hip dysplasia is fovea alta (delta angle, <10°). 4 This is measured on an MRI/MRA coronal slice in which both the acetabular sourcil and fovea capitis are best visualized.

Apr 25, 2013 · Nötzli et al. reported the abnormal superior position of the fovea capitis, also referred to as “fovea alta,” in the adult dys-plastic hip as a potential radiographic diagnostic marker. These authors quantified the position of the fovea capitis along the femoral head with the use of the delta angle measured on radiographs in the ...

Fovea alta had 69.4% sensitivity, 82.1% specificity, 67.2% positive predictive value, 81.0% negative predictive value, and 75.6% overall accuracy as an indicator of DDH. Conclusion: Fovea alta shows promise as a strong MRI marker of DDH.

Abnormal superior position of the fovea capitis femoris on MRI, also referred to as fovea alta, is seen in the adult dysplastic hip 39).

Results: The hypothesis that the "fovea alta" is characteristic for the dysplastic hip was confirmed. In dysplastic hips the typically wider fovea lays on average 30 degrees more cranial, touching the weight-bearing area over 11 degrees.

The results suggest that fovea alta may be a valuable diagnostic tool for identifying hip dysplasia, with practical implications for early intervention. Developmental dysplasia of the hip (DDH) is a common pediatric orthopedic disorder with an incidence of 1.5-2.5 per 1,000 live births.
