Low-contact dynamic compression plating of the clavicle

Abstract

Internal fixation of the clavicle is rarely necessary. When it is warranted, the clavicle's complex three-dimensional morphology and functional anatomy, proximity to vital structures, and the multidirectional biomechanical forces acting upon it place considerable demands on any implant used for skeletal fixation. We treated nine clavicles with the recently-introduced 3.5 mm low contact-dynamic compression plate (LC-DCP). Surgery was performed for symptomatic non-union in six patients, shoulder dysfunction following a malunited fracture in one, for an open fracture in one, and for an acute fracture associated with brachial plexus injury in one. After an average follow-up period of 17 months union was secured in each case. The advantages afforded by the 3.5 mm LC-DCP in internal fixation of the clavicle with its uniquely demanding anatomical and biomechanical characteristics are discussed.
