  • Osteotomy guide
    Patent number: 12357321
    Abstract: An osteotomy guide (100,500,600) guides cutting of a bone (300). The guide (100,500,600) has an anterior end (106,506,606) and a posterior end (108,508,608) that are spaced from one another along a transverse direction. The guide (100,500,600) has an inner surface (102,502,602) that faces the bone (300), and an outer surface (104,504,604) opposite the inner surface (102,502,602) along an outer direction (Do). The guide (100,500,600) includes a transverse guide surface (138,538,638) that extends along a transverse axis (AT) along the transverse direction so as to define a transverse cutting path into the bone (300). The guide (100,500,600) includes an ascending guide surface (134,534,634) that extends along an ascending axis (AA) along an ascending direction so as to define an ascending cutting path into the bone (300). The transverse and ascending axes (AT,AA) intersect one another.

  • Osteotomy guide
    Patent number: 12324591
    Abstract: An osteotomy guide (100) includes an inner surface (102) that faces the bone (300), and an outer surface (104) opposite the inner surface (102) along an outward direction (Do). The inner surface (102) defines proximal and distal bone contacting regions (118,120) that are spaced from one another by a gap (124) that extends into the inner surface (102) towards the outer surface (104). The guide (100) includes an ascending guide surface (134) that extends along an ascending direction so as to define an ascending cutting path into the bone (300). The guide (100) includes a transverse guide surface (138) that extends along a transverse direction so as to define a transverse cutting path into the bone (300).
