M.E.Müller: Atlas: Fracture 13-A1

Humerus, Distal,
extra-articular fracture,
apophyseal avulsion 0,43% of the total
6,03% of the femur
16,30% of the segment

31 fractures 13,2% group 48%M, 52%F

187 fractures

61%M, 39%F

18 fractures 7,6% group

Lateral epicondyle Medial epicondyle, non incarcerated +Q Medial epicondyle, incarcerated

These are extra-articular fractures of the distal humerus, with apophyseal avulsion of the medial or the lateral epicondyle, incarcerated or not. Ref. Manual of Internal Fixation:
184 - 187. 448 - 449.
Surgeon. RO, MS, CB.

All of these fractures are of easy surgical reduction. They should be provisionally fixed, either with Kirschner wires or with the small fragments bone clamps, and definitive internal fixation performed with a 4.0 mm. cancellous screw. If there is a well placed Kirschner wire, it can be left in place in order to neutralize the torsional loads or be used as a guide to insert a cannulated screw.

The screw must be strongly tightened in order to increase the interfragmentary frictional force, thus blocking the torsional and shear loads.
