Biomechanical Comparison of Monofascicular and Bifascicular Reconstruction of the Dorsal Ligaments of the Trapeziometacarpal Joint

Key Points

• Bifascicular reconstruction technique restores original stability to the trapeziometacarpal joint, while monofascicular reconstruction does not suffice.
• Key evidence from biomechanical testing indicates significant improvement in joint stability with bifascicular methods after surgery.
• Observational analysis conducted on two reconstruction techniques examines stability outcomes in the trapeziometacarpal joint post-operation.
• Findings indicate that ulnar ligament reconstruction is not necessary for achieving dorsoradial stability following bifascicular techniques.
