Epiphysis compression plate 3.3538 series

femurdistallocking

Instrument set for the correction of bone curvature with use of wedge-shaped incision consists of: • implants (wedge distance plates, screws) • instruments for bone incision and implants insertion • Instructions for use. The purpose of this treatment is to restore straightness of the lower limb. The curved bone is incised and then the wedge distance plate, which maintains performed incision and required angle of correction, is implanted. Straightness of the lower limb is defined by the line that is drawn between three characteristic points: the center of femoral head [1], the center of knee joint [2] and the center of distal tibia epiphysis [3]. If these 3 points cannot be connected by the straight line, the lower limb is considered curved. The curved bone distributes unequal loads on the knee joint, which may cause its inflammation. Straightening the knee joint should restore equal distribution of knee loads. In the case of the knee inflammation, it is allowed to perform such correction, so the healthy side of the knee transfers greater loads. There are two methods of straightening the knee joint: 1. The closing wedge osteotomy The surgeon performs a transverse incision of the tibia, or lateral or anterior in- cision of the femur {it depends on the limb curvature), removes the wedge piece of the bone, connects the open edges and unites the bone with a plate or staples. 2. The opening wedge osteotomy The surgeon performs a transverse incision of the tibia, or lateral or anterior inci- sion of the femur, then wedgely opens it and inserts: distance plate with wedge, or bone graft and distance plate without wedge, to hold the wedge opening.
