Sternal Reconstruction for Refractory Pectus Excavatum From Facioscapulohumeral Muscular Dystrophy

Area of Science:

• Biomedical Engineering
• Thoracic Surgery
• Medical Device Innovation

Background:

• Facioscapulohumeral muscular dystrophy (FSHD) can lead to severe chest wall deformities like pectus excavatum.
• Pectus excavatum in FSHD patients often causes progressive respiratory dysfunction and recurrent infections.
• Traditional surgical correction methods may be challenging in complex cases.

Observation:

• A 44-year-old male with FSHD and pectus excavatum presented with severe respiratory issues and chest deformity.
• A patient-specific, 3D-printed sternal implant was designed in collaboration with bioprosthetic engineers.
• The customized implant was approved by the Food and Drug Administration (FDA) prior to implantation.

Findings:

• Successful surgical implantation of the customized sternal plate was achieved.
• The patient experienced relief from refractory pectus excavatum.
• This innovative approach addressed a complex surgical challenge in a patient with a rare neuromuscular disorder.

Implications:

• Customized 3D-printed implants offer a promising solution for complex pectus excavatum cases.
• This technology can improve surgical outcomes in patients with underlying neuromuscular conditions.
• Bioprosthetic engineering and advanced manufacturing are transforming reconstructive surgery.
