Open and Arthroscopic with Mini-Open Surgical Hip Approaches for Treatment of Pigmented Villonodular Synovitis and Concomitant Hip Pathology

Figure 3

Preoperative anteroposterior (a) and frog-leg radiographs (b) of the left hip in Case demonstrate a cam deformity. Preoperative coronal T2-weighted fat-saturated (c), axial T2-weighted (d), and sagittal T2-weighted fat-saturated (e, f) magnetic resonance sequences with intravenous contrast reveal a multilobulated low signal lesion (arrow in d) measuring approximately 4.0 × 1.1 × 3.4 cm within the posterior/inferior aspect of the hip joint, with an associated large joint effusion. A = anterior; P = posterior.
