Variable Angle Plating Systems Treat Calcaneal Fractures

Two novel plating systems allow surgeons to adapt screw trajectory to match patient anatomy and fracture pattern.

The DePuy Synthes Trauma 2.7 mm variable angle locking calcaneal plating (VA LCP) system features new plate designs for leading surgical techniques, including the lateral extensile approach and the minimally invasive approach. The low-profile, pre-contoured plates are designed to treat both simple and complex fractures, with multiple fixation points targeting key areas of hard cortical bone in the calcaneus. Additionally, innovative instrumentation is available to assist in fracture reduction.

The DePuy Synthes Trauma 3.5 mm VA LCP medial column fusion plating system with variable angle locking technology offers advanced stabilization capabilities for fusion applications. Plantar and talus extension medial column fusion plates are also available, which allow the surgeon to independently compress each joint through the plate, gaining up to 6 mm of compression, as well as angulating the screws towards specific fragments of bone.

Additionally, a screw targeting clamp instrument set provides the ability to maintain compression while inserting screws through targeted areas, which is especially useful in challenging fusion cases. An adjustable rail ensures screw placement of solid or cannulated screws, in sizes ranging from 3.5 mm through 7.3 mm in diameter. The DePuy Synthes Trauma 2.7 mm and 3.5 mm variable VA LCP systems are products of DePuy Synthes (West Chester, PA, USA), a Johnson & Johnson (New Brunswick, NJ, USA) company.

“This is a comprehensive and versatile system of plates and screws that may be used to treat a broad array of calcaneal fractures through open or minimally invasive techniques,” said Michael Swords, DO, director of orthopedic trauma at Michigan Orthopedic Center (Lansing, USA). “As a surgeon who takes care of these injuries, the design of the plating system has the elements required to successfully treat calcaneus fractures.”

The calcaneus is the largest of the tarsal bones and the largest bone of the foot, and is responsible for transmitting the majority of the body's weight from the talus bone to the ground. It serves as the insertion point for three muscles: the gastrocnemius, soleus, and plantaris, which have a variety of functions including plantar flexion of the foot, flexion of the knee, and steadying the leg during standing. Calcaneal fractures are typically linked to injuries from falling from a height, automobile accidents, or muscular stress.
