LCP Rotation Correction Plate 2.0
Fractures of the metacarpals and proximal phalanges which heal in malposition can lead to severe impairment of hand function. In particular, rotational misalignments are problematic because of crossing and scissoring digits whenever full flexion of the fingers to a fist is attempted. Optimal recovery of hand function includes the meticulous restoration of alignment, length and rotation of digits and metacarpals. A careful approach needs to be chosen in order not to further compromise the soft-tissue situation which again requires proper reconstruction. The fixation has to be stable enough to facilitate immediate active and passive finger exercises.
The LCP rotation correction plate 2.0 enables intraoperative correction of malrotation, adjustment to the bone and restoration of correct alignment, prevents scissoring of the digits, and is easily adaptable to condylar-near fractures.
The LCP rotation correction plate 2.0 is anatomically precontoured, has a low plate-and screw profile, rounded edges and polished surfaces which minimize irritation of soft tissue and ligaments. The plate features a 2.5?mm slotted hole in the medial lateral direction. This oblong hole, positioned transversally to the shafts axis, enables intraoperative verification of the result of the reduction and, where required, intraoperative correction of the rotational axis of the bone. The optimal posture of the digit can be set through loosening and tightening of the cortex screw in the transverse hole.
The plate is available in shaft lengths of 34?mm (3 combination holes) or 40?mm (4 holes) which allows fragment-specific treatment of metacarpal fractures and fractures of the proximal phalanges. Both versions are 1.3?mm thick, and available in stainless steel and CP titanium, as well as sterile and nonsterile.
