AOTrauma Webinar:  Why Do Patients Get Infection?

May 30, 2017 14:00 CET

Main Presenter: Olivier Borens, MD (Switzerland)
Chat Moderator: Stephen Kates, MD (USA)

Surgical site infections after trauma are debilitating and costly. They are feared by the surgeon and the patient alike. The incidence of this complication can be decreased by proper preoperative, intraoperative, and postoperative management.
The goal of this webinar is to present easy-to-use tools and strategies that will lead to a decrease in the incidence of infection.

Anatomical reduction

Anatomical reduction of the articular fracture component and fixation with absolute stability is mandatory.

Lateral versus medial condylar fractures
The operative procedures for lateral condylar fractures (B1.1-type fractures) and medial condylar fractures (B1.2- and B1.3-type fractures) are comparable. A lateral condylar fracture treatment (B1.1-type fracture) is shown here.

Usually this fracture requires a buttress plate as simple screws may not hold the reduction as securely.

Clamps

Indirect reduction may be attempted by external manipulation of the fractured fragment using clamps. The accuracy of reduction should be checked with an arthroscope if no arthrotomy is carried out. In cases where adequate closed reduction is not achieved the joint must be opened in order to carry out an anatomical reduction of the joint surface. This may also be necessary to repair the lateral meniscus which is often injured in association with these fractures.

Lag screw application

Once reduction of the joint fragment is obtained, two partially threaded cancellous bone screws are inserted to securely fix the fracture. In cases of good bone substance, stable fixation may be easy to obtain and no further implants are needed.

Washers

The cortex in the lateral tibial head is thin. Therefore, the use of washers is advised.
