A method for limiting growth of a bone growth plate in children is achieved by using a Tethered X-Plate as depicted in Fig 1. The Tethered X-Plate, made out of titanium, is composed of a centre section (1) in the centre of which a small hole (4) is located. It has four extensions (2) in which four holes (3) are located in which accept four screws (6). The centre to centre distance between two horizontal holes (2) is 16 mm for adolescent and 14 mm for children under the age of 10 years. The four holes (4) are smoothly tapered (5) so that the screws (6) could be inserted in multi-directions as decided by a surgeon and as depicted in Fig 3. The surgeon by inserting a 0.8 mm temporary guide pin through the central hole (4) directly into the bone growth plate would be able to precisely locate the Tethered X-Plate and the multi-directional flexibility would allow the surgeon to install the screws (6) parallel to the patient's specific growth plate.
