We experienced a case of a 34 year-old man who ruptured his pectoralis major due to bench press exercise. Operation was performed three months after injury resulting in satisfactory functional repair but the patient was not satisfied with the cosmetic. Rupture of the pectoralis major is a rare illness with only about 100 reports found so far. In many of these reports, surgery achieved good results for complete rupture cases.
However, there were fewer reports on old cases, but many of those available showed that the operation achieved good functional results, but there were not so many good cosmetic results.
