1 Trauma Hoffmann II Compact External Fixation System Modular System for Upper Extremity Foot

2 Introduction In 1938, Raoul Hoffmann, a surgeon from Geneva, Switzerland, designed a revolutionary External Fixation System. The basic features of this system were its modular design and the ability to reduce fractures or to make post operative corrections to the alignment of fragments in three planes with the frame in situ. The Hoffmann II Compact 1 has built upon these principles, and today is the gold standard in modular external fixation. Certainly, the Hoffmann II family of products is unmatched in its ease-of-use, versatility, and patient comfort. You will find in the following pages the benefits and advantages of the Hoffmann II Compact, and how the system will help patients heal and return to their normal lives Pin to Rod Coupling Rod to Rod Coupling 3.

3 Features & Benefits Versatility and Ease-of-Use are the keys to an effective external fixator. The Hoffmann II Compact gives the option to build a variety of joint-bridging and non-bridging frames with simple, modular components. You have the choice to place the pins and build the frame which is best suited to each individual case. You have complete control of the system to make it do what you want it to do. With the patented Snap-Fit Technology, stable frame building is simple, and it is possible to reduce the fracture, make post-operative corrections, and treat soft-tissue damage with the frame in situ. You can click on and click off couplings and rods as your treatment requires. Light-Weight and Advanced component materials create a Low- Profile, Radiolucent Frame which adds to patient comfort and fracture healing management. You can make the frame as rigid or elastic as you see necessary. The components are Color-Coded and there are just a handful of High Quality Instruments in the system. This makes the Hoffmann II Compact very manageable in the Operating Room. Sterile-Packed Procedural Kits are available which makes the system Ready when you are. 3

4 Features & Benefits With full Independent Pin Placement, you can easily build a frame to treat fractures close to a joint, capture fracture fragments, or to stay clear of damaged soft-tissue areas. Related Stryker Products The system can be used together with other Stryker systems to give the surgeon the Full Package of fracture treatment.

5 Relative Indications & Contraindications Relative Indications Due to its versatility, the Hoffmann II Compact System is indicated for fixation of fractures in the upper extremity and the foot. It is particularly suited for the following indications: Distal Radius Fractures (intra or extra-articular) Fractures of the Foot Other indications including: Osteotomies Paediatric Fractures Fractures with Severe Soft-Tissue Damage Relative Contraindications If uncertainty exists with regard to the anatomic location of the neurovascular structures due to posttraumatic destruction, the device should be used with extreme caution. Under these circumstances, the pins should be inserted under direct vision. The presence of extensive internal fracture fixation devices Pre-emptive medical condition Bone Pathology 5

6 Components The Hoffmann II Compact System offers two types of clamps in order to build the right frame for the right indication. The standard 4-Hole Pin Clamp is designed to build a variety of frames. The modularity of the system allows you to build different frames using the same basic components. The Peri-Articular Clamp is designed to treat extra-articular fractures of the distal radius. The clamp allows Ø3mm half-pins to be inserted parallel to the radial joint. This frame then allows early joint mobility during fracture healing. It is also possible to bridge the joint with the Peri-Articular Clamp as shown here. This frame is used as additional fracture support when also using limited internal fixation. 6

7 Components The system also includes four different types of couplings. All of the couplings are designed with the patented Snap-Fit mechanism which allows complete versatility of the frame. The Pin to Rod Coupling connects Ø3mm or Ø4mm Apex Pins to a rod. This feature can be used to capture a fracture segment, to build a frame using completely independent pin placement, or to build a peri-articular frame by using them in combination with a Curved Rod. The Ø5mm Rod to Rod Coupling connects Ø5mm rods together or a rod to a post. It can be used to build any standard frame. It can also be added to an assembled frame to help build a more stable construct if needed. The Ø5mm/Ø8mm Rod to Rod Coupling allows you to connect a Ø5mm rod from the Hoffmann II Compact System to the Ø8mm rod of the Hoffmann II System. This could be helpful in the ankle/ foot area where bridging to the foot is necessary, or to connect a humerus frame to a radius frame. The Tube to Rod Coupling connects a Ø15mm Compression/ Distraction Tube to a Ø5mm rod or post. 7

8 Components The Hoffmann II Compact System offers connecting rods and tubes in different materials from which the surgeon can choose. Carbon Fiber Rods offer radiolucency and relative elasticity with a lightweight construct. Stainless Steel Rods can be used if high frame rigidity is required. Semi-Circular Curved Rods are also available in stainless steel. Periarticular frames can be built using this component. It is sometimes necessary to compress or distract a fracture site. The Compression/Distraction Tube allows the surgeon to fine-tune the osteosynthesis either intra- or postoperatively. 8
