VA-LCP Midfoot/Hindfoot System

Andrew Sands, Michael Castro, Juan Gerstner, Leslie Grujic, Stefan Rammelt, Michael Swords, Ian Winson

The Variable Angle Locking Midfoot/Hindfoot System offers two plates for the fixation of calcaneus fractures and a new plate for medial column fusion.

The Compression/Distraction Device is a very versatile instrument that can be used across numerous applications to reduce fractures or optimally align bones in preparation for fusion.

Variable Angle Locking Calcaneal Plate

The Variable Angle Locking Calcaneal Plate is indicated for traditional plate fixation of calcaneus fractures. The benefits of such locking technology include an ability to insert a screw at the best angle for the most optimal purchase in smaller bone fragments and a minimized risk of joint penetration in cases where fracture patterns demand screw placement in close proximity to an articular surface.


Variable Angle Locking Anterolateral Calcaneal Plate

The Variable Angle Locking Anterolateral Calcaneal Plate is indicated for minimally invasive posterior calcaneus fracture fixation in combination with 3.5 mm or 4.0 mm cortex screws. The Anterolateral Calcaneal Plate is used to support the articular surface of the subtalar joint. The additional screws are used to fix the fragments of the calcaneus required by the specific fracture pattern. The number and size of screws used to fix the fracture is dependent upon the fracture pattern, bone quality, and the weight of the patient. A minimum of three screws should be used in divergent positions to provide sufficient stability.


Medial column fusion

The new Variable Angle LCP Medial Column Fusion Plate system is indicated for advanced stabilization and fusion in Charcot foot and severe arthritis. The system comprises plates for application on the dorsomedial, medial, and plantar aspects of the foot as well as medial placement with talus extension. Using the compression/distraction instrument enables independent compression of selected joints.

Compression/Distraction Device

The Compression/Distraction Device is a very versatile instrument that can be used across numerous applications to reduce fractures or optimally align bones in preparation for fusion. Multiple devices can be used in combination for multifragmentary fractures or for the control and alignment of several affiliated bones. This set is not limited to use in the foot and ankle and is regularly used as an intraoperative holding device for fractures and osteotomies to obtain optimal alignment prior to fixation.

Case 1: Ladder fall

A 58-year-old woman (Fig 1), who had fallen from a ladder 9 weeks earlier, had indications of a malunited fracture and was referred to the clinic by a family physician.

The malunion had to be treated with an osteotomy to reconstruct the joint and regain normal function. The osteotomy was fixed with the VA Locking Calcaneal Plate (Figs 2 and 3).


Case 2: 70-year-old patient

A 70-year-old female patient (Fig 1) had a long history of increasing painful deformity of her foot. She also noted increasing gait problems. There was no history of initial trauma. The examination showed severe rigid flatfoot deformity.

An extended triple arthrodesis was performed. Medially, the new Medial Column Plate was used, securing the talonavicular, naviculocuneiform, and tarsometatarsal joints (Fig 2). The X-plate is lateral and secured the calcaneo-cuboid joint. Two 7.3 mm screws were used to secure the subtalar joint.
