We report on a 54-year-old woman with rheumatoid arthritis who had severe femoral nerve palsy affected by a distended synovium
in the hip joint. Surgical exploration demonstrated a perforation of the iliopectineal bursa connecting with the hip joint.
The patient fully recovered from femoral nerve palsy after surgery. It was considered that synovitis of the hip joint had
developed following huge iliopectineal bursitis.
