Radiologic Case Study

摘要

A 38-year-old, elite-level American football defensive lineman presented with right groin pain after an acute hyperabduction injury of the right hip during play. Magnetic resonance imaging of the pelvis demonstrated a 5-cm gap between the symphysis pubis and an inferiorly retracted adductor longus muscle (Figure 1). A small dark crescent at the proximal margin of the tendon suggested a thin bone fragment remained attached to the displaced tendon (Figure 2). The adductor brevis, adductor magnus, and pectineus and gracilis muscles were intact. Fluid and edema signals were noted at the anterior margin of the right side of the symphysis pubis, with disruption of the aponeurosis producing a secondary cleft sign (Figure 3).
