Abstract: An epiphyseal plate clamping device, comprising: a pair of clamping pieces each having at least two through holes; and at least two screw assemblies to correspond to the at least two through holes of the pair of clamping pieces; where, the pair of clamping pieces are used to be placed upon two sides of an epiphyseal plate zone of a longer leg of an LLD patient, and the at least two screw assemblies are used to penetrate through a femur or tibia of the longer leg along at least two paths guided by the at least two through holes of the pair of clamping pieces to clamp an epiphyseal plate within the epiphyseal plate zone, thereby retarding a growth of new bone from the epiphyseal plate.

Abstract: A targeting apparatus for the correction of the deformity in proximal femur of a child is disclosed and includes a retention assembly; a cylindrical nail retention member tapered toward its half-spherical bottom end and including an upper through hole, a lower through hole, and a top cavity having inner threads for releasably secured to the retention assembly; a first locking nail including a forward threaded portion, an enlarged head, and a retaining recess in the head thereof; and a second locking nail including a forward threaded portion, an enlarged head, and a retaining recess in the head thereof. The invention has the advantages of reducing the area of wound when implanting the locking nails in the femur and saving labor during surgery.
