Long-term outcomes of pectoralis major transfer for scapular winging due to long thoracic nerve palsy: results after a median follow-up of 17 years.

The results of the present study indicate that PM transfer augmented with an achilles tendon allograft for scapular winging due to LTN palsy leads to functional improvements that persist in long term. These functional improvements likely translate to better QoL based on their association.
