First Metacarpal Dorsal Periosteal Flap Suspensionplasty For Management of Thumb Basal Joint Osteoarthritis.
Trapeziectomy is the standard surgical option for end stage carpo-metacarpal joint (CMCJ) osteoarthritis of the thumb. Excision of the trapezium creates a space between the metacarpal and the scaphoid. Different techniques have been described to suspend the first metacarpus during the healing phase. We describe an alternative technique of soft tissue interposition that provides strong stability of the first metacarpal bone, is easy to perform and precludes unnecessary exposure of the scaphoid which can be easily done by junior surgeons during their learning curve.
