Perkin's line

Perkin's line is a line drawn on an AP radiograph of the pelvis perpendicular to Hilgenreiner's line at the lateral aspects of the triradiate cartilage of the acetabulum.{{cite journal | vauthors = Noordin S, Umer M, Hafeez K, Nawaz H | title = Developmental dysplasia of the hip | journal = Orthopedic Reviews | volume = 2 | issue = 2 | pages = e19 | date = September 2010 | pmid = 21808709 | pmc = 3143976 | doi = 10.4081/or.2010.e19 }}{{cite journal | vauthors = Agarwal A, Gupta N | title = Risk factors and diagnosis of developmental dysplasia of hip in children | journal = Journal of Clinical Orthopaedics and Trauma | volume = 3 | issue = 1 | pages = 10–4 | date = June 2012 | pmid = 25983450 | pmc = 3872792 | doi = 10.1016/j.jcot.2011.11.001 | url = https://doi.org/10.1016/j.jcot.2011.11.001 }}

Clinical use

Used in conjunction with Hilgenreiner's line, Perkin's line is useful in the diagnosis of developmental dysplasia of the hip; the upper femoral epiphysis should be in the inferomedial quadrant on a normal radiograph. Lateral displacement relative to Perkin's line is indicative of DDH.
