In severe trauma cases, it

is necessary to have a good

partnership, whether it is a

colleague in the surgical theatre

or an effective and trustworthy

system that allows you to bring the

focus to where it belongs - on the


The TenXor system, a hybrid

External Fixator for peri- and

intra-articular fractures of the

lower extremity is especially

designed to fulfill the needs of

today’s surgeons. The advanced

technology helps to provide

simplicity and efficiency of


The right focus - possible

with the TenXor system.

Thanks to technical features

like the patented* “Snap Fit”

mechanism, adaptation of height

from the Wire Post and an

unlimited range of motion on

the ring, the TenXor delivers the

features surgeons need during a

trauma procedure. Focus is on

the patient and their injuries. The

TenXor adapts to the treatment

requirements of the injury

without compromising the clinical


During wire insertion,

concentration can be completely

tissues. The TenXor provides the

possibility to adapt the frame even

for non parallel wires.

Do you have a need to change

the frame elasticity during the


The compatibility with the

modular Hoffmann II system and

Monotube TRIAX system allows

adaptation of frame elasticity to

the healing process.

The TenXor system is a part of

the Hoffmann II family. The

combination of simplicity and

versatility solves your daily

challenges in the surgical theatre

more effectively.

Features & Benefits

Ease of Use

The “Snap Fit” mechanism is designed

to provide a quick, easy and secure

frame construction. With a small

number of components and a few

bolts and nuts to tighten, working on

the frame is much facilitated. The

minimal instrumentation needed

is compatible with the Hoffmann II


High technology carbon material

of the rings provides a better

radiolucency and the etched end of

the olive wires allow a simple removal

without additional x-ray control.


Simple Adaptation

The 5/8 open carbon rings facilitate

the selection of the ring size by

sliding it over the extremity directly

during surgery. Due to the “Snap

Fit” mechanism, absolutely no

pre-assembling is necessary. All

components have direct positioning

access to the ring construction.

Additionally the “Snap Fit”

mechanism provides the possibility

to add or remove components to

create the optimal stability during the

treatment with a “Click”.


The compatibility with the

Monotube TRIAX and the

Hoffmann II systems provide the

adaptation of elasticity during

treatment. It also adds the option of

independent pin placement and joint

bridging if desired. The “Snap Fit”

mechanism with a “Click” delivers the

solution of a dynamic system.

Hoffmann II brochure (ref.-no. 5075-

1-000) and the Monotube TRIAX

brochure (ref.-no. 5075-2-500).


Features & Benefits

Free Wire


The TenXor system has been designed

for effective wire placement adaptable

to fractures and anatomical needs.

The wires can be placed prior and

independently to the frame assembling.

The Ring Clamp provides unlimited

positioning on the ring and the

attachable Wire Post has a height

adjustability up to 2.5 cm with

angulations of +/-20°.



Only a few instruments and the

compatibility with the

Hoffmann II instruments facilitate the

work significantly.

The self-explanatory wire tensioner

renders an optimal tensioning of the



Your system for effective solutions.


Relative Indications & Contraindications

Since external fixation devices are

often used in emergency situations to

treat patients with acute injuries, there

are no absolute contraindications for

use. The surgeon’s education, training

and professional judgement must

be relied upon to choose the most

appropriate device and treatment for

each individual patient.

If uncertainly exists with regard to the

anatomic location of the neurovascular

structures due to post-traumatic

destruction, the device should be used

with extreme caution. Under these

circumstances, the wires and pins

should be inserted under direct vision.



• Severe multi fragmentary tibia

plateau fractures, e.g. Schatzker

type (4), 5, 6

• Severe multi fragmentary pilon

fractures, e.g. Rüedi & Allgöwer type

2, 3

• Severe distal femur fractures, e.g. AO

33B, 33C

• Secondary fixation after failure or

infection of primary fixation

• Less complex fracture pattern with

severe soft tissue damage, e.g.

Tscherne type C2, C3,

Gustillo Andersen type (2), 3



• Patients with compromised immune


• Non compliant patients who would

not be able to ensure proper wire and

pin care

• Pre-existing internal fixation

that prohibits proper wire or pin


• Bone pathology precluding pin

Injectable HA


HydroSet is a self-setting calcium

phosphate cement indicated to fill

bony 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 indicated only

for bony voids or gaps that are not

intrinsic to the stability of the bony


HydroSet cured in situ provides an

open void/gap filler than can augment

provisional hardware (e.g K-Wires,

Plates, Screws) to help support

bone fragments during the surgical

procedure. The cured cement acts

only as a temporary support media

and is not intended to provide

structural support during the healing

HydroSet is an injectable,

sculptable and fast-setting bone

substitute. HydroSet is a calcium

phosphate cement that converts to

hydroxyapatite, the principle mineral

component of bone. The crystalline

structure and porosity of HydroSet

makes it an effective osteoconductive

and osteointegrative material, with

excellent biocompatibility and

mechanical properties 1 . HydroSet

was specifically formulated to set in

a wet field environment and exhibits

outstanding wet-field characteristics 2 .

The chemical reaction that occurs as

HydroSet hardens does not release heat

that could be potentially damaging

to the surrounding tissue. Once set,

HydroSet can be drilled and tapped

to augment provisional hardware

placement during the surgical

procedure. After implantation, the

HydroSet is remodeled over time at a

rate that is dependent on the size of the

defect and the average age and general

health of the patient.


Injectable or Manual


HydroSet can be easily implanted via

simple injection or manual application

techniques for a variety of indications.

Fast Setting

HydroSet has been specifically designed

to set quickly once implanted under

normal physiological conditions,

potentially minimizing procedure



HydroSet does not release any heat as

it sets, preventing potential thermal


Excellent Wet-Field


HydroSet is chemically formulated

to set in a wet field environment

eliminating the need to meticulously

dry the operative site prior to

implantation. 2


The composition of hydroxyapitite

closely matches that of bone mineral

thus imparting osteoconductive

properties. 3

Hardware during surgical


HydroSet can be drilled and tapped

to accommodate the placement of
