BONE PLATE INTERNAL FIXATOR DEVICE

The present invention relates to a bone plate internal fixator device (101; 501; 701) for epiphysiodesis, comprising a pair of holding elements (102, 103; 502, 503; 702, 703), each one of the holding elements (102, 103; 502, 503; 702, 703) respectively comprising a through hole (104, 105; 504, 505; 704, 705) configured for receiving a respective fixing screw (301) to a bone; the bone plate internal fixator device (101; 501; 701) further comprising a central portion (106; 506; 706) which structurally connects and constrains the holding elements (102, 103; 502, 503; 702, 703) with each other. The central portion (106; 506; 706) is flexible so as to allow flexing of the bone plate (101; 501; 701) and angular opening of the bone plate (101; 501; 701) during evolution of the epiphysiodesis surgery. Flexing of the bone plate further allows a relative flexing between the holding elements (102, 103; 502, 503; 702, 703), and wherein the fixing screws (301) always remain coplanar to a plane which encompasses a flexing angle, and wherein the axis of each fixing screw (301) remains substantially perpendicular to the respective holding element (102, 103; 502, 503; 702, 703).
