Autologous rib cartilage grafts provide stable sternotomy repair for pectus arcuatum. This biocompatible graft shows viability and new bone formation, offering satisfactory results with minimal morbidity.

Area of Science:

Thoracic surgery
Orthopedic surgery
Regenerative medicine

Background:

Pectus arcuatum, characterized by sternal angle protrusion and cartilage deformity, often requires surgical correction.
The modified Ravitch procedure is a common surgical approach for pectus arcuatum.
Grafting may be necessary for stable correction after osteotomy, but data on cartilage graft behavior in human bone defects is limited.

Observation:

This study presents a case of using an autologous rib cartilage graft for sternotomy stabilization during pectus arcuatum repair.
The graft's viability and integration were assessed using computed tomography (CT).

Findings:

Computed tomography confirmed the viability of the autologous rib cartilage graft.
Evidence of new bone formation was observed at the graft site, indicating successful integration.

The autologous cartilage graft served as a biocompatible substitute for sternotomy stabilization.

Implications:

Autologous rib cartilage is a readily available, biocompatible material for sternotomy stabilization in pectus arcuatum repair.
This approach yields satisfactory surgical outcomes with minimal patient morbidity.
The findings support the use of autologous cartilage grafts in thoracic reconstructive surgery.
