The ideal treatment of acute fractures of the humeral shaft remains controversial. It is generally accepte that conservative treatment is best for isolated closed of the humerus shaft. But recently, in case of surgical mangement,
intramedullary
nailing treatment has reported good results.
Authors have analysed 20 cases of the humeral shaft fractures shaft treated with colsed intramedullary nailing at the department of orthopedic surgery, Lee-Rha general hospital from June 1991 to December 1993 with minimal 1 year follow up
@ES The results were as follows
1. In the 20 cases, theage between 20 and 40 years old was taken place 60% and the most common cause of injury was traffic accident(75%)
2. It was worthwhile to define the relationship between union time and Winpuist-Hansen classification which used in femoral shaft fracture. And the average bone union time was 8 weeks except 3 cases, especially delayed union was found
in
type 3 of Winquist-Hansen classification. But 2 cases were united after 9 months follow up without secondary procedure.
3. Problem in Seidel nailing was failure of expansion of distal portion andin Russel-Taylor nailing was impairement of internal rotation of shoulder and delayed union due to iatrogenic distraction at the fracture level during operation.
In according to the above results totreat the humeral shaft fracture, closed intramedullary inter locking nailing was satisfactory enough to obtain bone union and early of shoulder motion. Also, the Wiquist-Hansen classification is
useful
duide tofind the bone union time inthe treatment of humeral shaft fracture with interlocking nail.
