  • Publication number: 20210322070
    Abstract: An intramedullary nail assembly includes a body and an inlay. The body has an outer surface and an opposing inner surface. The outer surface extends from a leading end of the body to a trailing end of the body. The inner surface defines a cannulation that extends into the trailing end towards the leading end. The body comprises a leading body portion that defines the leading end, and a trailing body portion that defines the trailing end. The inlay is positionable within the cannulation of at least one of the leading body portion and the trailing body portion. The inlay includes an engagement member configured to engage the body to removably lock the inlay within the cannulation of the body.

  • Patent number: 8454606
    Abstract: A device for treating fractures of the femur and includes an intra-medullary pin (1) with a central longitudinal axis (2), a front piece (3), which is introduced into the medullary channel of the femur, a rear piece (4) and a hole (5) going through the rear piece (4) at an angle to the longitudinal axis (2) with a non-circular cross-section (6). A sliding sleeve (10) that is introduced through the hole (5) with non-circular cross-section, has a front end (11), a rear end (12), a central longitudinal drilling (13), an outer sleeve surface (14), an inner sleeve surface (15) and a longitudinal axis (16). A longitudinal bone fixation element (20) with a longitudinal axis (21), a head piece (22) with fixation element (23), which is brought into engagement with the femur head on use and a shaft (24), which is introduced co-axially into the sliding sleeve (10), whereby the outer sleeve surface (14) of the sliding sleeve (10) has a non-circular cross-section (17), at least in a partial region.

  • Patent number: 7850690
    Abstract: A femoral fracture treatment device including: an intramedullary pin (1) with a central longitudinal axis (2) and a passage (5) of non-circular cross-section (6) through a proximal portion (4) of the pin oblique to the longitudinal axis (2), a sliding sleeve (10) configured to pass through the non-circular passage (5), a longitudinal bone fixing element (20) having a head portion (22) with fixing means (23) for engaging the femoral head and a shaft (24) that may be coaxially introduced into the sliding sleeve (10). Both an external jacket surface (14) of the sliding sleeve (10) and an internal jacket surface (15) of the sliding sleeve (10) have non-circular cross-sections at least in a partial section. The shaft (24) is rotatably mounted in the longitudinal bore (13) of the sliding sleeve (10), and locking means are provided at the free end (27) of the shaft (24), such that rotation of the longitudinal bone fixing element (20) relative to the sliding sleeve (10) can be optionally locked or released.
