Clinical Example: Transcondylar distal humerus fracture repaired with Herbert screws

Transcondylar distal humerus fractures are usually high energy comminuted difficult fractures, technically difficult to manage. Anatomic reduction, rigid fixation and early motion are desirable, if technically possible. There are a variety of techniques for fixation. Here, Herbert screws were used to secure the two central purely osteochondral fracture fragments to each other and to the proximal humerus.

Open reduction via olecranon osteotomy.  The ulnar nerve is  retracted with a penrose drain. The articular surface was reconstructed, then secured to the shaft. After recovering the rotated anterior articular fragment, the anterior and posterior halves of the central articular component were secured with .062" pins. These pins were replaced one at a time with Herbert screws.

Later in the case, the small medial osteochondral fragment was secured with absorbable sutures (not shown).

In similar steps, the reconstructed central articular component was secured to the proximal humerus with pins. Once satisfactory reduction was obtained (not yet, as seen here...), the pins were replaced by more Herbert screws. This allowed fixation of the purely osteochondral segments without prominent harware.

Screws were secured from the central articular component to the more proximal humeral cortices.

These provided biplanar fixation, eventually with two screws in each direction.
