Bilateral peroneal nerve palsy secondary to posterior dislocation of the proximal tibiofibular joint in rheumatoid arthritis.
Bilateral peroneal nerve palsy due to posterior dislocation of the proximal tibiofibular joint in a 72-year-old rheumatoid patient is described. Operative findings showed thickening of the synovial membrane of the proximal tibiofibular joint and a neuroma at the peroneal nerve at the fibular head. The cause of posterior dislocation of this joint in the wake of rheumatoid inflammation is discussed.
