Abstract
We have reported five cases of Jeffery's type fracture of the elbow. The average age of the patients was 7 years, ranging from 4 to 11 years.
This fracture is caused by valgus stress due to physiological valgus of the elbow where by the axial pressure is inflicted on the extended elbow. At the moment of injury, we find that compression force on the radial side leads to radial neck fracture. While traction force to the ulnar side causes two types of injury: one is avulsion fracture of the medial epicondyle or rupture of the medial collateral ligament and fracture of the olecranon the other is fracture of the proximal ulnar shaft.
As for treatment of Jeffery's type fracture, accurate reduction of the radial neck is necessary for the rotational limitation of the forearm. Further correct reduction of the olecranon and repair of the medial collateral ligament are also important so as to not cause instability of the elbow.
We selected operative care for all cases. We have found good results.
