[Neuropathic arthropathy of the shoulder].

Neuropathic arthropathies is a destructive and deforming joint process related to a disruption of propioceptive and nocioceptive innervation. Growth factors, neurological and vascular factors might be involved. Diabetes, alcoholic neuropathy or syringomyelia appear as the most common causes. We report the case of a 61-year-old woman affected by syringomyelia, with a neuropathic arthropathy of the shoulder. Differential diagnosis includes neurological diseases, septic arthritis, tumours and other destructive arthropathies such as aseptic nechrosis, chronic osteomyelitis, synovial chondromatosis, metabolic diseases (gout, chondrocalcinosis) or repetitive haemarthrosis in haemophilia.
