Designing and Prototyping of New Device for Scapholunate Ligament Repair

摘要

Scapholunate instability, caused mainly due to tears in the scapholunate interosseous ligament (SLIL), may result in chronic pain, hand weakness, and lack of motion. Several open surgery procedures are used to repair it however long recovery time, widespread scarring and movement limitations are associated. Focusing on arthroscopy surgery, the combination of arthroscopy techniques and a prosthesis could be a good solution to manage it. A new prosthesis to substitute the SLIL was designed and manufactured. The design process was assessed by expert surgeons in wrist arthroscopy and the prototype manufactured allowed to analyze advantages and drawbacks of the adopted solution.
