QID 212 (Type "212" in App Search)
A 25-year-old man sustains a left leg injury during a motorcycle accident. A radiograph is provided in Figure A.

Figures A and B demonstrate pre and post-operative radiographs of a comminuted proximal tibia fracture treated with a long locking plate. Compartment syndrome is a significant complication associated with this fracture. However, there is no greater risk of compartment syndrome with use of this specific construct plate. Long lateral locking plates have been shown to put the superficial peroneal nerve at risk with insertion of distal locking screws. Use of a larger incision and careful dissection down to the plate in this region may minimize the risk of damage to the nerve.

Deangelis et al performed a cadaveric study evaluating 14 extremities and the relationship between the superficial peroneal nerve to the percutaneous screws of the 13-hole proximal tibia Less Invasive Stabilization System (LISS) plate. The average distance from the superficial peroneal nerve to the center of holes 11, 12, and 13 was 10.0 mm, 6.8 mm, and 2.7 mm, respectively. In 12 of 14 legs (86%), the superficial peroneal nerve was 5.0 mm or less from the center of hole 13.

Cole et al reviewed his experience of 77 proximal tibia fractures treated with the LISS plate. He reported a high rate of union (97%) with only 2 infections, 2 nonunions, 1 nerve palsy, and 8 patients with an angular malunion approaching 10 degrees.
