[Brachial plexus paralysis of infectious origin: report of four cases].
BACKGROUND
Brachial plexus palsy (BPP) may occur after septic osteoarthritis of the shoulder. BPP is a rare, well recognized complication. The pathophysiology is thought to be either ischemic nerve damage secondary to occlusion of vasa nervorum or extrinsic compression. Early diagnosis and treatment of the infection are needed.


METHODS
We report the cases of three infants aged less than three months and one six-day-old newborn infant who presented with an authentic BPP due to an osteoarthritis of the shoulder. The diagnosis of osteoarthritis relied on clinical, biological and radiological signs. In one case, the causal germ (Enterobacter) was isolated. The diagnosis of the palsy was based on clinical signs. EMG performed on one patient, showed signs of abnormal motor pattern. Following intravenous antibiotics and percutaneous drainage, all infants completely recovered.
