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.

Throughout this treatment option illustrations of generic fracture patterns are shown, as four different types:

A) Unreduced fracture
B) Reduced fracture
C) Fracture reduced and fixed provisionally
D) Fracture fixed definitively

2 Principles of modular external fixation top

The modular external fixator is optimal for temporary use. It is rapidly applied without need for intraoperative x-rays and can be adjusted later.

Details of external fixation are described in the basic technique for application of modular external fixator.

Specific consideration for the distal humerus are given below.

Pin placement

For safe pin placement make use of the safe zones and be familiar with the anatomy of the humerus and the proximal forearm.

Soft tissue dissection

Blunt dissection of the soft tissues and the use of small Langenbeck retractors will prevent damage to muscular, vascular and neurological structures.

Prepare a channel for insertion of the pin, using a blunt clamp down to the bone. If there is any doubt an incision should be made big enough to prove that the drill sleeve (for the humerus a must) will have direct contact with the bone.

Be especially careful of the radial nerve, which spirals around the humeral shaft and, in the distal third, it intersects the lateral intermuscular septum.

Pearl: non-bridging fixator

If the fracture is far enough from the joint and there is good bone quality, sometimes it is possible to apply the external fixator only to the humerus, leaving the elbow joint free.
