[Control of disordered wound healing using sonography based on postoperative follow-up after TEP implantation]

Clinical diagnosis of early postoperative complications remains a major issue in patients undergoing total hip replacement. Early diagnosis is essential because (clinical) signs of inflammations as fever or elevated white blood count already reflecting late complications. The goal of our study was to evaluate postoperative monitoring for early detection and treatment of hematoma and abscess following total hip replacement. 308 patients undergoing total hip replacement were postoperatively monitored for the development of hematoma and abscess, comparing routine ultrasound to on demand ultrasound in case of clinical signs of infection. The diagnostic puncture was 6.5% (10/154) in group A (on demand ultrasound) versus 11.7% (18/154) in group B (routine ultrasound). Infections were seen in 5.2% (8/154) of patients in group A compared to 0.6% (1/154) in group B, leading to surgical intervention in 3.3% (5/154) group A, respectively 0.6% (1/154) in group B.
