Sternal reconstruction with bone cement block using the rigid plate fixation technique.

Area of Science:

• Oncology
• Orthopedic Surgery
• Biomaterials Science

Background:

• Chondrosarcoma is a rare malignant tumor of cartilage.
• Sternal tumors require complex surgical management and reconstruction.
• Chest wall reconstruction presents significant surgical challenges.

Observation:

• A 48-year-old female presented with sternal pain, and imaging revealed a suspected primary tumor in the upper sternal body.
• The patient was diagnosed with chondrosarcoma.
• A chest computed tomography scan was used for initial diagnosis.

Findings:

• Sternal resection was performed for the chondrosarcoma.
• Chest wall reconstruction utilized a custom bone cement block composed of polypropylene mesh and polymethylmethacrylate.
• The SternaLock System was employed for fixation of the reconstruction to the manubrium and ribs.

Implications:

• This case highlights a successful approach to sternal chondrosarcoma resection and reconstruction.
• Custom bone cement blocks offer a viable solution for complex chest wall defects.
• Minimally invasive fixation systems can facilitate stable reconstruction and good postoperative recovery.
