Volition® - The Evidence Based Ankle Fracture Solution
Anatomically designed by dedicated foot and ankle surgeons to optimise their armamentarium in treating all types of foot and ankle disorders. Featuring patented V-Lock® Technology.
Ankle fracture plating that delivers better results.
The Volition® Ankle fracture system aligns with the extensive research development and outcome identified by Prof. Lyndon Mason and Mr. Andy Molloy. The Volition® ankle fracture system provides the surgeon options to assist in the optimal reduction of posterolateral, posteromedial, medial and lateral malleolar fractures.
Working collaboratively with clinicians, OrthoSolutions can proudly present Volition® Ankle fracture system.
Clinical identification shows that the posterior malleolar fracture patient cohort have traditionally had poor functional outcomes. Alongside the extensive commitment and research that has been conducted by Prof. Lyndon Mason and Mr. Andy Molloy in posterior fracture management, a need to develop a system that addresses the issues identified was clinically needed to help improve the outcome for the patient.

Volition® System Details
- Volition® Ankle Fracture Plates are available in six variables:
- Anatomic fibula plate
- Straight fibula plate
- Anatomic medial malleolar plate
- Posteromedial tibial plates (Type IIB)
- Posterolateral tibial plates (Type IIA)
- Posterior tibial plates (Type Ill)
- Volition® Plating System non-locking screws are compatible with washers and any screw hole in the plates.
- Volition® Plating System locking screws are compatible with any screw hole. Locking screws are not compatible with washers.
- The Volition® Ankle Fracture Plating system has 22 plating options for a variety of ankle fracture complexities. These include multiple patented designs and anatomically contoured:
- Anatomic Medial Malleolar plates: D977,646
- Lateral Anatomic Fibular plates: D974,562
- Posterolateral Tibial plates: D928,322
- Posteromedial Tibial plates: D977,645
- Olive wires may be inserted in any screw hole. Alternatively, k-wires may also be used to temporarily affix the plate to the bone through specific k-wire holes or wire slots within the plates.
- All plate screws may be inserted through the screw holes in a 15° conical range of trajectories. All plate screws utilise the same size driver. Each driver has a non-working AO-quick connect and a standard sized torx working end.
- Volition® Plating System non-locking screws are compatible with washers and any screw hole in the plates.
Type II anodized plates increases fatigue strength by roughly 25% compared to Type III, thereby reducing risk of device fracture
- Type II anodize plates produce anti-galling properties + Type III anodize screws result in minimizing coldwelding for easier implant removal, if required
- Optimization of plate strength by not needing to utilize softer plate material/alloy which allows screws to plastically deform/tap into it
- Preservation of debris-free wound site as no implementation of screw coating. Some coatings, such as a TiN coat, enable metal-tapping of the plate, and can flake off over time leaving debris
- Utilization of V-LockTM Technology minimizes cross-threading between an off-axis locking screw and plate thereby increasing overall construct strength
- Generous fillets creating soft edges and transitions on the plates along with ultra-low profile nature result in minimizing the likelihood of soft tissue irritation
- Ø2.7, Ø3.5 & Ø4.0mm screw diameters offered can be used in non-lock, fixed angle lock and variable angle locking (30° conical capability) modalities
- Self-tapping, yet blunt tip minimizes potential soft tissue irritation
- NL screw design of cancellous-type OD/ID ratio with hybrid-type pitch producing an increased purchase
- Cheater’s lag/bite upon insertion satiates tactile feedback; tapered ID in the neck significantly increases bending strength
- Ø4.0mm cannulated screws housed within set for additional fixation needs
Patent-pending plate/screw interface allows smooth, easy locking on or off-axis
- Proprietary technology (PCT/US19/60895 ) incorporates a differential thread angle at the interface, allowing variable axis locking with minimal cross-threading
- Minimizes pushing of the screw away from desired trajectory and towards perpendicular upon insertion
- Decreased propensity to strip plate/screw interface due to minimal cross-threading
Advantages of Volition® Plating
Our Patent-pending plate/screw interface allows smooth, easy locking on or off-axis.
Anterior Ankle Fracture Plates
The Volition® anterior ankle fracture plates offer the surgeon options to capture varying sizes of rotational, distal anterior tibial fracture fragments or Tillaux fracture fragment types.
The Volition® plates anterior plates offer the surgeon the
ability treat anterior ankle fracture patterns with specific
anatomic plates and using a single surgical approach.
AITFL suture holes on plate to assist with Wagstaffe repair.
The Volition® plates anterior plates are low profile and
are contoured to sit at the anterior tibial plafond without
causing impingement.
The screw hole placement within the Volition® plates is
designed to allow interfragmentary compression and to
provide a raft of screws deep to the articular surface.
Lateral anatomical fibular plate
The twist from anterior (distal) to posterior (proximal) on the plate give several advantages listed below:
- Preferential placement of syndesmosis fixation from posterolateral to anteromedial.
- Distal anterior fixation allows assessment of PM reduction and fibula reduction on lateral radiograph as there is no metal work obscuring the posterior plafond.
- By moving incision 1cm anteriorly from lateral malleolar prominence it allows access to anterior incisura to confirm syndesmosis reduction.
- Wagstaff suture holes - Suture holes are in the average position of a Wagstaff fragment to allow AITFL repair.
- Fibular lengthening - A proximal oblong hole allows lengthening of the fibular by distal fixation with screws and then traction applied
Type 2A Plate
- Anatomically correct to typical 2A fracture patterns.
- Medialisation of distal end of fracture helps obtain safe zone distal position to keep out of incisura.
- Plate placement optimisation – a proximal oblong hole allows initial buttress of fracture and ability to move plate to optimal position.
- Access form medial approach – medial hole allows plate application form medial posteromedial approach.
Type 2B Plate
- Anatomically correct to typical 2B fracture patterns. Unlike other posteromedial plates on the market, the plate does not occupy the average fracture line but the fragment itself.
- Allows correct force application to reduce type 2B medial fracture with lateralisation and anterior force
- Plate placement optimisation – a proximal oblong hole allows initial buttress of fracture and ability to move plate to optimal position.
- Tibialis posterior protection – the plate aims to stay outside of the tibialis posterior sheath.
Type 3 Plate
- Anatomically correct to typical type 3 fracture patterns.
- Designed to typically be located between incisura safe zone and tibialis posterior sheath.
- Plate placement optimisation – a proximal oblong hole allows initial buttress of fracture and ability to move plate to optimal position.
- Tibialis posterior protection – the plate aims to stay outside of the tibialis posterior sheath.
- Angular placement of screws to optimally incorporate the plafond position.
Medial Plate
- Anatomically correct to typical medial wall blow out fractures. Arches anteriorly due to typical location of blowout.
- Can place plate on medial wall, or bend tab and place plate more distally to obtain home run screw on anterior collicular fracture.
- Plate placement optimisation – an oblong hole allows initial buttress of fracture and ability to move plate to optimal position.
Ultra low profile to decrease risk of soft tissue irritation. Available in several lengths ranging from 2 hole up to 8 hole
