[Diagnosis and therapy of local infections after surgical management of proximal femoral fractures].

Postoperative infections after trochanteric and intracapsular hip fractures are rare. Critical clinical observation of the wound during the early postoperative period and the evaluation by sonography as well as the determination of the C-reactive protein are important factors in the diagnosis of early haematoma and wound infections. If revision surgery of suspected infections is immediately performed, good long-term results are to be expected. Infected hemialloarthroplasties and loosened total hip arthroplasties (THR) should be retrieved. If a mild infection is present, one stage revision arthroplasty is indicated. In case of gram-negative infections, however, alloarthroplasties should be removed and the total hip replacement should be delayed for 3 to 6 months.
