Hoffmann LRF

Circular External Fixation System

Circular external fixation for fractures, joint contractures, fusions, limb lengthening, deformity correction and bone and soft tissue reconstruction in pediatric patients and adults.

Stable. Smart. Simple.

The Hoffmann LRF is a modern circular fixation system designed to reduce construct complexity and simplify application. The typical LRF construct features two or more rings bridged by three to four telescopic struts with multiplanar, ball-jointed fixation bolts. Once applied, the LRF can be unlocked for gross frame adjustment and fracture reduction. The LRF can be finely adjusted to aid in precise limb alignment and definitively locked with secure, advanced locking features. Tight component interfaces may reduce sheer forces and promote construct stability.

    • Engineered for greater flexibility to offer more surgical options
    • Advanced technology designed for ease of application
    • Potential to minimize the number of components for ease of use and light weight
    • Carbon Fiber Rings are radiolucent to aid in reduction and healing assessment
    • Unique pin clamp design allows for easy application of multiplanar pin fixation
    • Mechanically compatible with Hoffmann II and Hoffmann III

Hoffmann LRF circular external fixation overview

Based on the long-standing tradition of simplicity and reliability of the original Hoffmann Fixator, the Hoffmann LRF design adds new versatility to match today’s biological repair and reconstruction methods. The typical LRF construct features two or more rings bridged by three to four telescopic struts with multiplanar, ball-jointed fi xation bolts. Once applied, the LRF can be unlocked for gross frame adjustment and fracture reduction. The LRF can be finely adjusted to aid in precise limb alignment and definitively locked with secure, advanced locking features.

Hoffmann LRF frame range of motion

Once mounted, the LRF can be unlocked and used as a fracture reduction tool. In addition to the quick release mechanisms, all ball joints must be unlocked to achieve full range of motion. Ball joints allow for 12° of angulation from neutral.

Hoffmann LRF gradual correction system animation

The Hoffmann LRF gradual correction system introduces modern dynamic correction components into the LRF platform. The addition of hinged telescopic struts are designed to support a wide range of procedures including articulated distraction and the addition of telescopic motors further augment the Hoffmann LRF platform to take on indications requiring gradual corrective adjustments, such as equinus foot deformity correction.

Hoffman LRF bone transport

Continuing the legacy of innovation found in the Hoffmann external fixation product family, the market's first dedicated bone transport strut is now available in the modern Hoffmann LRF circular external fixation system.
