Abstract
The present invention relates to a porous structure having a controlled pattern (1), which is repeated in space, in three dimensions, said porous structure enabling the production of surgical implants for filling in bone defects. According to the invention, said structure is characterized in that said pattern (1) consists of three wings (2) arranged in a star shape, each angle (A) formed between two wings being substantially equal to 120°, each wing having a generally rectangular shape and being hollowed (3) at the center thereof. Each of the three wings (2) of said pattern is advantageously beveled at its free end or tip (4), and the width of the base (5) of each bevel is slightly greater than the thickness of the wings (2) of which it forms an extension.
