The FusionFrame Ring Lock System is the updated Ilizarov Method circular external fixation apparatus, specifically engineered to address the extensive requirements of foot and ankle specialists. Briefly described, the FusionFrame is designed to support a construct that may allow post-operative adjustments; patient mobility is dependent on clinical judgment and treatment plan. Its design is intended to support axial and circumferential stability, streamlined preassembly, minimally invasive application, system versatility designed to support a range of external fixation configurations.

The FusionFrame consists of externally mounted Rings and ancillary components that are interconnected with Rods. The construct is attached to the bone with a combination of percutaneously applied tensioned Wires and / or Half-Pins.  The system is designed to allow customization of frame constructs based on patient anatomy and surgeon preference, from static frames through complex foot & ankle deformities.

Applications

Charcot-Neuroarthropathy also known as hereditary motor and sensory neuropathy or peroneal muscular atrophy, consists of a group of disorders that affect peripheral nerves. This disease often leads to deformities such as drop foot, hammertoes, and a collapse of the arch and joints in the foot. FusionFrame is intended to support external fixation in the management of these deformities during the often months-long recovery period.

Flap

In basic terms, a flap is a portion of tissue that can be dissected, elevated, and inset into a non-anatomic position as a consequence of its vascular supply and outflow. FusionFrame is designed to support positioning of bony structures during treatment allowing for the transplant of the flap and left in place until the flap has integrated and/or removed at the surgeons discretion.

Wound Care

Open wounds or sores often resulting from diabetes can be treated using FusionFrame as a way to protect the site and may be used as part of a treatment plan that restricts weight bearing while graft or other means of treatment are pursued.

Ankle Trauma

In many cases where using external fixation to hold ankle fractures in place is required, the external fixator stabilizes the ankle until a second surgery for Open Reduction Internal fixation (ORIF) consisting of locking plates and screws is used. FusionFrame is designed to support external fixation as part of a treatment strategy; surgical approach determined by surgeon but can also be used as definitive treatment for immediate weightbearing in conjunction with ORIF.

Quick Connect Struts

The Quick-Connect Struts are designed to support controlled adjustment for achieving controlled adjustments for the purposes of fracture management, limb lengthening and deformity corrections. Switching between controlled and quick adjustment is done by pushing/pulling the sleeve over the threaded segment.

FULL RING

There are four diameters of Full Ring sizes: 140, 160, 180, and 205mm. All Rings are 8mm thick. They provide the scaffolding and structural support for the overall frame and are the primary platform from which all other components are connected.

HALF RING
140mm – 205mm

HALF RING

here are four diameters of Half Ring: 140, 160, 180, and 205mm. All Rings are 8mm thick. They provide the scaffolding and structural support for the overall frame and are the primary platform from which all other components are connected.

5/8 RINGS
140mm – 205mm

5/8 RINGS

The 5/8 Rings were designed with an open segment entailing 3/8 of the overall circumference of the ring to allow for increased range of motion around a joint. The 5/8 Rings are available in 140, 160, 180 and 205mm diameters.

FOOT PLATES
140mm – 205mm

FOOT PLATES

There are four sizes of Foot Plates: 140, 160, 180, and 205mm, each of which are compatible with their corresponding Ring sizes.

WALKIE PUCKS
140mm – 205mm

WALKIE PUCKS

Four to six Walkie Pucks may be added to the inferior side of the Foot Ring to assist the patient with weight bearing and ambulation.

THREADED RODS
60mm – 400mm

THREADED RODS

There are four diameters of Full Ring sizes: 140, 160, 180, and 205mm. All Rings are 8mm thick. They provide the scaffolding and structural support for the overall frame and are the primary platform from which all other components are connected.

QUICK CONNECT STRUTS
Three Lengths Available

QUICK CONNECT STRUTS

The Quick Connect Struts provide a systematic means for achieving controlled distraction (or compression) for the purposes of limb lengthening or fracture fixation. There are three sizes of Struts.

OBLIQUE SUPPORTS

OBLIQUE SUPPORTS

Oblique Supports may be used to connect a Half Ring, mounted across the Foot Plate, to the most distal ring on the tibial block, for a more symmetrical distribution of loads between the distal tibia and foot.

UNIVERSAL HINGES

UNIVERSAL HINGES

The Universal Hinges provide an unconstrained cardan joint that may be added to any threaded element.

THREADED SOCKETS
40mm / 60mm

THREADED SOCKETS

Threaded Sockets may be used as fixed spacers to allow rapid connections between two levels of Rings in a frame construct. They are available in 40 and 60mm lengths.

PLATES
20mm / 30mm

PLATES

Plates are used as horizontal spacers, swivels and outriggers. They are available in two sizes: 20mm (two hole) and 30mm (one hole, one slot).

90° Hinges
