Abstract:

Objective　To explore anatomic features, adjacent structures and the projection of the clavicle, and provide anatomic basis for treating clavicle fracture through the external plate fixation.　Methods　15 adult cadaveric specimens (30 sides) were selected to respectively observe subclavian vessels, brachial plexus, the clavicle and coracoid process. The projection area of the subclavian vessels, brachial plexus on the clavicle was measured and compared.　Results　Projection area of the neurovascular bundle was at the medial and middle 1/4 segment of the clavicle. Minimal distance from neurovascular bundles to the lower edge of the clavicle was about 0.42 cm and 0.57 cm at the left and right sides respectively.　Conclusions　During the fixation procedure using the external plate, the hole drilling on the medial and middle 1/4 segment of the clavicle should be careful and directed postsuperiorly to anteroinferierly, and the length of screw have to be considered, for protecting adjacent neurovascular bundles.
