3.5 mm LCP Low Bend Medial Distal Tibia

Michael Wagner, Micheal Schutz, Dean Lorich, Brent Norris, Sean Nork, Phil Kregor

The 3.5 mm LCP low bend medial distal tibia plate is indicated for the fixation of both simple and complex intra and extra-articular fractures and osteotomies of the distal tibia. Due to the wide variability of the distal tibia, the existing plate for such complication does not consistently fit the anatomy particularly in smaller stature patients.

The design of the 3.5 mm LCP low bend medial distal tibia focuses on the relationship between the distal plate tip and the medial malleolus. A lower head height (minus 1.96 mm) compared to the current 3.5 LCP medial distal tibia increases contact with the crest of the medial malleolus. The shaft twist is more gradual and has a higher bend distance of 70 mm compared to 44 mm in the previous implant (measured from where the twist begins to the distal tip). The larger radius of curvature (R125 compared to R58) and the higher starting point leads to a smoother transition. It has the same screw hole configuration and pattern as the existing plate, except for the articulated tension device hole which was removed.

Cadaver tests showed that the low bend design, especially the metaphyseal bend, has a better fit on the average tibia. The plate has a left and right version and is available in stainless steel and titanium. It comes in lengths from 4 holes (109 mm) up to 14 holes (239 mm).

LCP Small Fragment Percutaneous Instrument Set

The LCP small fragment percutaneous instrument set consists of a comprehensive series of aiming arms, insertion handles, and instrumentation to facilitate percutaneous, subcutaneous/submuscular insertion of various plates to allow minimally invasive surgery for reduced soft-tissue damage. It may also reduce image intensifier exposure and time in the OR because the arm targets the holes and facilitates screw insertion.

The set enables aiming for all three positions of the combination hole (locking, neutral, and compression). The instruments snap into the aiming arms for quick assembly and removal. Color coding helps easy identification of compatible instruments. The aiming arm is made of carbon fiber for radiolucency. The insertion handle attachment point provides three points of fixation when connected to the plate.
