The present inventions relate to a system and method for altering growth of bones. More precisely, the system is an orthopedic apparatus for correcting rotational deformities and limb length discrepancies. A system of cable-couplings with linking members is used, the linking members being posts or screws traversing bones. Due to the flexibility and adaptability of the system and its components, the cable-coupling members may be installed at varying angles and locations while allowing for growth arrest or rotational corrections of said bones. A method to limit growth using cable-couplings systems is also provided.

The invention relates to a card clothing (20) for a card (1), and to a card (1). The card clothing (20) has a working direction (16), a foundation (21) and a plurality of clothing tips (26). The clothing tips (26) are formed from U-shaped wire hooks (22) which are pierced through the foundation (21) at a penetration angle (α) and each have limbs (24) forming two clothing tips (26) and a back (23) connecting the two limbs (24). The backs (23) are at a right angle to the working direction (16). The backs (23) form a base plane (29) on a side of the foundation (21) lying opposite the clothing tips (26). The wire hooks (22) have a total height (a) perpendicular to the base plane (29), and the limbs (24) each have a free limb length (c) perpendicular to the base plane (29) protruding from an exit point (27) out of the foundation (21) to the clothing tip (26). The limbs (24) are bent counter to the working direction (16) by a knee angle (β) at a knee height (b) from the clothing tip (26) and perpendicular to the base plane (29). Furthermore, a setting line (28) running perpendicularly to the base line (29) and through the exit point (27) of the respective limb (24) is determined. The clothing tips (26) are arranged on the setting line (28) or by a tip offset (d) away from the setting line (28) in the working direction (16).
