title: Neuropathic arthropathy: a forgotten diagnosis? Two recent cases involving the hip.
abstract: Two cases of neuropathic arthropathy of the hip are reported. One was the first manifestation of tabes dorsalis in a 74-year-old man, whereas the second occurred in a 47-year-old woman with a history of spina bifida and L2-L5 epidural lipoma. Radiographic joint destruction occurred within five and three months, respectively. The main clinical and radiological features of neuropathic arthropathy are reviewed, and diagnostic pitfalls are discussed. There are no specific laboratory tests or histologic findings. This now rare condition should be routinely considered in patients with severe joint destruction contrasting with minimal pain. The reasons for the decision to use trochanteric-iliac coaptation in one of our patients and a wait-and-see approach in the other are explained. The literature is reviewed. Ten cases treated by joint replacement have been reported. However, neither joint replacement nor arthrodesis seem capable of restoring satisfactory hip function.
