Painful pectoralis major myospasm as a result of sternal wound reconstruction: complete resolution with bilateral pectoral neurectomies

Abstract

We report a patient with a highly unusual and previously unreported complication with the use of the pectoralis major muscle to treat the infected median sternotomy. The diagnosis of painful myospasm was made by a combination of physical findings and exclusion of other conditions such as recurrent infection. Treatment by pectoral denervation was relatively simple and highly successful. Patients with chest-wall pain after sternal wound reconstruction should have myospasm entertained as a possible cause.
