This case study details successful treatment of complex distal femoral nonunion with deformity using a retrograde segmental transport nail. The innovative technique corrected malalignment, torsion, and shortening, achieving bony consolidation and restored limb function.
Area of Science:
- Orthopedic surgery
- Biomedical engineering
- Trauma reconstruction
Background:
- Distal femoral fractures treated with antegrade nails can lead to nonunion and complex deformities.
- Such deformities include varus angulation, external torsion, foreshortening, and translation malalignment.
- Nonunion presents significant challenges in restoring limb alignment and function.
