The clinically visible swelling (proximal lateral thigh) is a subcutaneous collection ( about 16 ccs) with mobile internal echoes. From the subcutaneous plane, it extends to the femur cortex, screw-plate, and encircles them. Lateral craniocaudal collection extension was maximum (about 210 mm length); reaching just distal to the distal plate end. Anterior extension of about 115 mm. Medial extension about 90 mm. Posterior extension about 90 mm. The approximate volume of collection around the femur is 150 cc. The vastus intermedius muscle deeper fibers are involved in the collection.
No right hip joint effusion.
