ATTN: Medical Dopers -- Winged Scapula?

I’ve been doing some research but it has failed to answer my question.

Can a winged scapula be caused by an injury such as a fall? All the information I’ve talked about deals with either congenital defects or diseases. Thanks.

Most cases are due to direct injury to the long thoracic nerve or its origin in the brachial plexus, eg. stabbing. However, the comments below seem to indicate that it may arise indirectly due to injury.
