Multicentric osteolysis nodulosis and arthropathy (MONA) is a rare skeletal dysplasia characterized primarily by progressive osteolysis, particularly affecting the carpal and tarsal bones, accompanied by osteoporosis. In addition, it features subcutaneous nodules on the palms and soles, along with the progressive onset of arthropathy, encompassing joint contractures, pain, swelling and stiffness. It is caused by a deficiency of the Matrix Metalloproteinase-2 (MMP2).

Explant analysis can provide important understanding of how artificial joints perform in the human body. The articulating surfaces of the metacarpal head and the radius cup from a chromium nitride coated metal-on-metal Motec wrist implant were analysed. Due to bone resorption and aseptic loosening, the implant was removed after 6 years in the patient, and metallosis was observed during removal.

Metal hypersensitivity is a rare and often underestimated complication, as shown by the small number of published studies, particularly concerning the upper limbs and the hand. However, the increase in the annual number of trapeziometacarpal arthroplasties underlines the importance of better understanding of this problem. We performed a study based on data from the revision of trapeziometacarpal prostheses to assess the incidence of this complication and to define a sequence of radiological changes to detect metal hypersensitivity.

We report a rare case in which the entire capitate was replaced by free nonvascularized autologous bone grafting due to a giant cell tumor. Moreover, a Maestro wrist prosthesis (second type) was subsequently implanted after two failed motion-preserving procedures. At the 6- and 8-year follow-ups, we observed complete but asymptomatic avascular bone necrosis around the entire capitate peg without evident failure of the carpal component.
