Disclosed is an intramedullary nail system, apparatus and method of implantation. The intramedullary nail (20) is suitable for implantation into paediatric patients. The intramedullary nail (20) is one-piece comprising proximal (22), medial (24) and distal (26) portions. A continuous cannula extends through each of portion (22, 24, 26). The proximal portion (22) has a first longitudinal axis and an end with at least one finger extending parallel the first longitudinal axis. The proximal portion (22) has an internal thread along the cannula extending from the end surface (34) towards the medial portion (24). The proximal portion (22) has first and second linear channels formed through it. The first and second linear channels have respective first and second openings on one side of the proximal portion (22) and a common third opening. The medial portion (24) joins the proximal portion (22) at a bend (32) as viewed in a medial-lateral plane that forms an angle between the proximal portion (22) and medial portion (24) of about 165 degrees. The medial portion (24) has a third linear channel. The third linear channel is non-parallel to either of the first and second channels. The distal portion (26) joins the medial portion (24) at a bend (68) forming an angle of about 175 degrees. The distal portion (26) has fourth and fifth linear channels that are parallel to each other and a sixth linear channel between and non-parallel with said fourth and fifth channels. |
