Reconstruction of sternoclavicular defect with completely detached pectoralis major flap.

Sternoclavicular joint infection is very rare. Osteomyelitis is a known complication of septic sternoclavicular joint. Once this condition is diagnosed, aggressive management including antibiotic and surgical debridement is warranted. Patients are often left with sizeable sternoclavicular defects that may need surgical reconstruction. In this report, we describe the use of a completely detached pectoralis major flap for the reconstruction of a large sternoclavicular defect after resection for osteomyelitis. Briefly, after the debridement of the infected sternoclavicular joint, the pectoralis major was detached from its sternoclavicular attachments and further detached from the humeral attachments rendering it completely detached on a vascular pedicle. The muscle was advanced to cover the defect and secured. Patient recovered well without any surgery related complication. She retained good use of the ipsilateral upper extremity. The pectoralis major can be completely detached to provide ample coverage for sternoclavicular joint reconstruction if needed.
