Management of complications of acetabular fractures

Surgical treatment of acetabular fractures represents a special challenge in the field of trauma surgery. Complications are mostly due to the trauma itself or are iatrogenic. The handling and strategy to overcome complications in acetabular surgery are oriented towards the type of complication and the time of occurrence. Generally, a differentiation is made between early perioperative complications and late complications. The present article describes the most frequent complications during the surgical treatment of acetabular fractures, discusses the various treatment options based on individual case examples and gives differentiated recommendations to overcome the complications. The treatment concept should initially comprise a comprehensive primary prophylaxis to prevent complications. In cases of early perioperative complications, e.g. postoperative wound infections, hemorrhage or incorrect implant positioning, rapid and systematic surgical revision should be performed. In contrast, the treatment of late complications (e.g. implant associated failures, secondary osteoarthrosis of the hip, periarticular heterotopic ossification, non-unions and late infections) depends on the clinical and functional condition of the patient. In symptomatic elderly patients secondary total hip replacement is usually a valid option, whereas younger patients with late complications can be candidates for joint-preserving procedures. The management of complications in acetabular surgery regularly requires intense patient guidance as well as thorough clarification and should be performed in specialized centers.
