Septic arthritis of acromioclavicular (AC) joint is a rare entity. It is generally seen in patients who are immunocompromised. Only 15 cases have been reported till now, with only one case series of 6 patients. We report a case of septic arthritis of AC joint in an immunocompetent child. A 9 years old girl presented with history of pain in left shoulder for 4 days associated with fever. No history suggestive of any immunocompromised state was complained. On local examination, a swelling of around 3 cm in diameter was found over left AC joint region with raised local temperature, tenderness on palpation and positive response in fluctuation test...

BACKGROUND: Implant-related infections are associated with impaired bone healing and osseointegration. In vitro antiadhesive and antibacterial properties and in vivo antiinflammatory effects protecting against bone loss of various formulations of vitamin E have been demonstrated in animal models. However, to the best of our knowledge, no in vivo studies have demonstrated the synergistic activity of vitamin E in preventing bacterial adhesion to orthopaedic implants, thus supporting the bone-implant integration...
