Tumours of the sternum can be either primary or secondary with malignancy being the most common etiology. Wide local excision of these tumours results in a midline defect which pose a unique challenge for reconstruction. As limited data on the management of these tumours exists in the literature, we hereby report 14 consecutive patients who were treated at our institute between January 2009 to December 2020. Most of them were malignant with majority of them, 11 (78%) patients, with manubrial involvement requiring partial sternectomy. Overall, the average defect size was 75 cm2. Reconstruction of the chest wall defect was done using a semi-rigid fixation: mesh and suture stabilization in 3 (21%) or suture stabilization in 7 (50%) and without mesh or suture stabilization in 3 (21%) patients. Rigid fixation with polymethyl methacrylate (PMMA) was done for one patient (7%). Pectoralis major advancement flap was most commonly used for soft tissue reconstruction with flap necrosis noted in one patient (7%). There was no peri-operative mortality and one patient required prolonged post-operative ventilation. On a median follow-up of 37.5 months, one patient (7%) had a recurrence. Sternal defects after surgical resection reconstructed with semi-rigid fixation and suture stabilization render acceptable post-operative outcomes.
