Several radiographic parameters identified pelvic discontinuity after THA
Recently published retrospective results showed preoperative evaluation with a combination of an anteroposterior pelvis radiograph, a true lateral radiograph of the hip and Judet films in combination with pelvic discontinuity criteria allowed researchers to identify pelvic discontinuity in all patients who underwent acetabular revision for the condition.
Researchers retrospectively reviewed 133 patients who underwent acetabular revision for pelvic discontinuity after total hip arthroplasty. Researchers also reviewed preoperative radiographic studies, including anteroposterior pelvis, true lateral hip, Judet, false profile and CT scans, to identify visible fracture lines, medial migration of the inferior hemipelvis and obturator ring asymmetry.
Results showed 87% of hips had a visible fracture line, 95% had medial migration of the inferior hemipelvis and 86% had obturator ring asymmetry when researchers solely used the anteroposterior pelvis view. When evaluated with lateral scans, researchers found 49% of hips had a visual fracture line. According to results, 77% of hips had a visual fracture line when evaluated with Judet views. The fracture line was visible in 75% of hips evaluated with a false profile view and in 71% of hips evaluated with CT. – by Casey Tingle
