Closed percutaneous K-wire stabilization for displaced fractures of the surgical neck of the humerus.

We report a series of 22 displaced fractures of the proximal humerus treated by percutaneous Kirschner wire stabilization. Poor results (69 per cent) in the older age group of patients is a reflection of the severity of the fracture and the difficulties of closed reduction. Reduction in a poor position in this series has led to a poor range of movement. Good functional results can only be expected with a good reduction. Experience of migration with smooth K-wires has resulted in a strong recommendation for the use of threaded pins.
