Treatment of humeral shaft fractures by closed fixation using multiple intramedullary Kirschner wires.
BACKGROUND
The purpose of this study is to present the results of closed fixation of humeral shaft fractures with multiple intramedullary Kirschner wires.


METHODS
Twenty-nine humeral shaft fractures in patients 14 to 60 years old were treated by closed fixation with multiple intramedullary Kirschner wires. Each patient was placed supine on the table and was administered general anesthesia. The fractured arm was held vertically up by a transolecranon traction, while the C-arm was kept parallel to the ground and opposite to the affected arm. A cortical window was created approximately 1.5 cm proximal to the olecranon fossa, after splitting the triceps. Under fluoroscopic control, multiple Kirschner wires were introduced retrograde therein, into the medullary cavity, to reach the humeral head. The wire tips were kept splayed to stabilize the fracture. Postoperatively, the limb was supported by an arm sling.


RESULTS
Twenty-five fractures (86.4%) healed with excellent clinical and functional results, in an average of 11 weeks. Union was delayed in two patients, and one fracture had a nonunion after repeated trauma. Movements at the shoulder and the elbow were excellent to good in 27 patients (93%), whereas 2 patients (6.8%) had significant limitation of extension at the elbow.


CONCLUSIONS
This technique has been found simple and effective in providing a stable fixation of transverse and short oblique fractures of the humeral diaphysis. Further study is required to evaluate this procedure in more extensive fracture patterns, as well as to compare the results with other methods of internal fixation.
