A variety of frames can be ana-tomically built with only 4 basic components which are based on the patented Hoffmann II “Click” Mechanism offering surgeons quick and easy solutions.

This system is compatible with the Hoffmann II Compact System giving the surgeon Complete Solutions for the Hand, Wrist, and Forearm.

2.0mm and 1.65mm Self-Drill-ing Self-Tapping Apex Pins allow pin insertion without pre-drilling which will Save Time in O.R.

The instrumentation is Simple and User-Friendly, and the system is Color Coded, so there is no lost time or confusion in the O.R.

The system offers Independent Pin Placement to adapt to the anatomy which is needed to ad-dress complex fractures and severe soft-tissue damage.

Low Profi le and Light Weight frame assemblies offer added com-fort to the patient.

The system is designed to facilitate fracture alignment and Reduction After Frame Assembly offering the surgeon more Freedom and Flexibility when building the frame.

Post-operative Corrections can easily be made while the frame is in place to insure proper anatomi-cal positioning throughout the healing process.

In 1938, Raoul Hoffmann, a Swiss

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

Original Hoffmann System underwent

considerable design improvements

over the years. Then in the late 90’s, a

group of renowned design surgeons1

and Stryker engineers developed the

innovative Hoffmann II and

Hoffmann II Compact Systems. These

systems signifi ed a giant step forward

in the treatment of bone fractures with

modular external fi xation frames.

Indeed, thanks to the light weight and

non bulky components, the Hoffmann II

Systems provide surgeons an unlimited

versatility, simplicity, and an unequaled

ease of use. The Hoffmann II Micro

System capitalizes on the experience

acquired during several decades with the

original Hoffmann System and with the

Hoffmann II and Hoffmann II Compact

Systems. It is made of stainless steel and

carbon composite materials to provide

optimal low profi le high resistance

features, and it has been designed to

answer the growing needs of small bone

injuries by ensuring ease of use,

versatility and patient comfort.

Relative Indications

The Hoffmann II Micro System is indi-cated for hand fractures. It is particularly suited for the following indications:

- Articular fractures- Comminuted Fractures- Severe open fractures (Grade 3)- Rolando fractures- Non unions and delayed unions- Fractures associated with infection- Acute Corrective Osteotomies- Bennett’s fractures- Burns and Contractures- Pathologic fractures- Small Joint Arthrodesis

Hoffmann II Micro Standard Frame Guide

Due to the versatility of the Hoffmann II Micro System, there is a virtually unlimited number of frame constructs.The surgeon has the choice to make any frame that will best heal the fracture. The following are the standard frames which are explained in detail in the Hoffmann II Micro Technical Guide

- Mid-Shaft Fracture of the Proximal Phalanx of the Index Finger

- Metaphaseal Fracture of the Proximal Phalanx of the Index Finger

- Inter-Articular Fracture of the Fifth Metacarpal with severe soft-tissue damage.

Relative Contraindications

- Patients with a compromised immune system.

- Non compliant patients who would not be able to ensure proper pin care.

- Pre-existing internal fi xation that prohibits proper pin placement

- Bone pathology precluding pin fi xation

HydroSet Injectable HA Bone Substitute

Fracture gaps are often seen in comminuted Distal Radius fractures. Some surgeons prefer to use bone substitutes to fi ll these gaps. Stryker offers an innovative HA Bone Substitute with HydroSet.

The injectable self-setting calcium phosphate material allows the surgeon to fi ll bone voids or gaps of the skeletal system (i.e., extremities, craniofacial, spine, and pelvis). These defects may be surgically created or osseous defects created from traumatic injury to the bone.

HydroSet is delivered in 3, 5, 10, or 15cc quantities. 3cc and 5cc are normally suitable for voids in the Distal Radius.
