Nonunion is a rare complication of metacarpal fractures and is usually associated with compound, open fractures with tissue loss and infection, or after failed surgical treatment. Repair by rigid osteosynthesis with plate and screws combined with autologous bone grafting has always been the treatment of choice for most patients. Such method allows early motion, although it has been proven that the presence of hardware may cause local soft tissue irritation. Often, hardware removal and tendon releases are necessary. We describe an original technique with a fixation method for the treatment of metacarpal nonunions, considering the excellent results attained with an intramedullary, headless screw for metacarpal fracture fixation. We report a series of three cases that evolved to bone healing with excellent clinical, functional, and radiographic outcomes.

Kienböck's disease is a clinical-radiological condition that can permanently affect wrist functionality and the patient's quality of life. Proper, pertinent diagnosis and treatment are required to avoid salvage procedures. Arthroscopic techniques have emerged as an important tool for the treatment of certain stages of the disease.We present a review of the literature and propose a treatment algorithm according to the stage of the disease, including arthroscopic techniques. We detail the surgical technique of arthroscopic scaphocapitate arthrodesis, and the functional outcomes obtained by our group.
