Midshaft Clavicle Malunion with an Atypical Posterior Apex Deformity by Ross Leighton in Orthopedics and Sports Medicine Open Access Journal (OSMOAJ) in Lupine Publishers
Purpose: We are presenting this pattern of a rare variant of a clavicle malunion with an apex posterior-inferior deformity. This occurred in an elite major junior hockey player during his draft season. This illustrates that such a deformity will most likely result in shoulder weakness, altered shoulder mechanics and may cause brachial plexus neurological findings. In addition, this can cause associated sterno-clavicular deformity which can lead to sternoclavicular joint subluxation secondary to the increased strain placed on the sternoclavicular joint from an apex posterior inferior malunited clavicle. Deformity of > 20 degrees in any direction interferes with normal motion and normal cortical strength even in a young patient.
