Bone plate for epiphysiodesis

Epiphysiodesis kit comprising:

• a bone plate for epiphysiodesis comprising:
• a first portion and a second portion structured to be fastened to epiphysis and metaphysis, respectively, of a long bone in a paediatric patient;
• said first and second portions being joined by a connecting portion structured to straddle a growth plate of said long bone;
• said first and said second portions being intersected by at least a first and at least a second opening, respectively, structured to receive two fixing screws for fastening to said long bone;
• said bone plate having a bilobal figure, such as an eight shape;
• at least one of said first and second openings comprising:
• a cup-shaped seat for housing a head of said fixing screw in a tiltable manner, said cup-shaped seat having an entry section structured to allow insertion of the head of said fixing screw and an exit section of an at least locally smaller size compared to a respective size of said entry section so as to retain the head of said fixing screw;
• wherein at least one of said first and second openings further comprises at least one recess which merges into the cup-shaped seat expanding the exit section away from the connecting portion, and wherein said at least one recess takes form of a tilted hole with respect to a central axis of symmetry of said cup-shaped seat, wherein the tilted hole locally widens an outer periphery, opposite the connecting portion, of the exit section of said cup-shaped seat, and wherein the tilted hole extends from a merging point on said cup-shaped seat away from both the connecting portion and the entry section;
• said two fixing screws with said heads, which can be inserted into said cup-shaped seat in the tiltable manner and a shank which is at least partially threaded and structured to pass through said first or said second opening, respectively, to engage with epiphysis or metaphysis respectively of the patient.
