Midshaft Clavicle Malunion with an Atypical Posterior Apex Deformity by Ross Leighton in Orthopedics and Sports Medicine Open Access Journal (OSMOAJ) in Lupine Publishers.
Abstract
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.
