Orthopedics and Traumatology
External Fixation
Orthofix
Orthofix is a company known worldwide for the development of
external and internal fixation solutions in the field of Traumatology
and Orthopedics.
In 1991, Promedon formed a strategic alliance with this international
company to offer these solutions in the South Cone.
All these options are easily implanted, minimally invasive and equally
safe and effective, which ensures high reliability, both in procedures
and results, and allows patients to recover their quality of life and
resume their usual activities almost immediately.
Benefits of Orthofix solution prostheses for external and internal
fixation:
 Maximum safety ensured by design and material.
 Innovative approaches to the treatment of pathologies.
 Minimally invasive treatment.
 Easy implantation thanks to a complete and innovative set of
instruments.
XCALIBER
(Argentina and Chile)
The XCALIBER line of external fixators belongs to the new generation
of radiolucent fixators, presented by Orthofix, designed for simplicity
and rapid application. Radiolucent: Highly resistant and lightweight.
Given their features, this line of external fixators can be used for a
wide range of indications and no additional accessories are
necessary.
These pre-assembled fixators cover most traumatological indications.
Minimal instrumentation is required and the fixators are positioned
using a minimally invasive procedure.
XCALIBER fixators are made of innovative composite polymer, a
radiolucent material which makes them more resistant and lightweight
than conventional fixators.
XCALIBER is the first long fixator with radiolucent body, articulated
ball-joints and clamps; therefore, fracture display is not obstructed
and fracture reduction is fast and easy. The forceps have been
redesigned for better handling, thus avoiding radiation of the
surgeon’s hands during the reduction process.
Three fixator configurations are available:
XCALIBER Meta-Diaphyseal Fixator: It is indicated for diaphyseal and
metaphyseal fractures and facilitates display of osseous callus
formation and bone healing.
XCALIBER Articulated Ankle Fixator: It is specially designed for tibial
pilon fractures and allows for early joint movement.
It provides stable fixation. Its articulated ball-joints enable correction
above 44º from straight position, in any direction, with the fixator in
place. Only one instrument (cam) is used for locking and unlocking
the fixator.
A radiolucent guide allows display of the rotational axis of the ankle
joint for appropriate screw positioning.
It has a distraction unit for ligamentotaxis.
XCALIBER Hybrid Fixator: It is indicated for periarticular fixation in
comminuted fractures and osteoporotic bone. More than four wires
can be used per ring for increased stability.
The rings cover 2/3 of the full circumference. Its articulated ball-joints
enable correction above 44º from straight position, in any direction,
with the fixator in place.
The telescoping body allows for fracture reduction and
compression/distraction.
LRS (Limb Reconstruction System)
(Argentina and Chile)
The LRS is a Limb Reconstruction System designed for limb
lengthening, reconstruction in bone loss and deformity correction.
The LRS includes different types of clamps (usually two or three)
which can slide on a rigid rail and be connected with compression
and distraction units.
This system uses osseous callus distraction for bone lengthening in a
variety of procedures such as bone transport, simultaneous
compression and distraction at different sites, monofocal lengthening,
bifocal lengthening, and correction of deformities with shortening.
Limb reconstruction and lengthening are mainly
indicated in cases of bone loss (with or without
shortening), deformity (with or without shortening) and
extreme limb shortening, in children as well as in adults.
The LRS can be used to achieve lengthening above 10
cm, thus not replacing the device with a longer one.
For comminuted fractures with bone loss, and for
nonunion or malunion, with or without osteoporosis, the
LRS can be used to achieve maximum stability as its
design allows for different bone screw positions in the
clamps along the whole bone length, depending on the
length of the rail used.
The right length of the limb reconstruction system is selected
according to the size of the limb to be treated and the distraction
(lengthening) required.
OsteoTite bone screws with hydroxyapatite coating (tricalcium
phosphate) can be used in metaphysis and diaphysis to ensure the
stability of the screw-bone interface.
LRS differential features:
 Highly stable.
 Surgical technique with short learning curve.
 Bone formation through gradual osseous callus distraction.
 Monolateral design for simple application, especially in the
femur .
The procedure is minimally invasive.
Patients are not in much pain as distraction is gradual, and can
continue to walk during treatment.
The restored bone is completely normal, and muscles, nerves and
blood vessels grow in response to the controlled lengthening, as they
do during growth.
Radiolucent Wrist Fixator
(Argentina and Chile)
It is an external radiolucent joint fixator, made of PEEK, for X-ray
follow-up and control of fractures.
Articular and Extra-Articular Fixator
• Wrist in adults
• Radius (extra-articular in adults)
• Humerus in children
Features:
• RADIOLUCENT (allows for display of fracture healing) and sterile
• Provided with a COMPLETE instrument kit
• Simple and minimally invasive prosthesis
• Resistant
• Disposable
Sheffield
(Argentina and Chile)
The Sheffield Ring Fixator was designed to provide maximum bone
support and treat simple as well as complex trauma.
It is indicated for acute trauma and limb reconstruction in the following
cases:
Acute trauma: Tibial articular fractures: In plateau and tibial pilon –
Tibial articular fractures with diaphyseal extension – High-energy
tibial diaphyseal fractures – Femoral fractures, particularly in the
distal region, and humeral fractures.
Limb reconstruction: Correction of post-traumatic, acquired or
congenital deformities (articular, oblique plane and multiplanar) The
Sheffield fixator is usually used in the lower limbs for foot and tibial
deformities, but is also used for femur and knee deformities. In
addition, it is used in the upper limbs, particularly the humerus. –
Arthrodesis: knee, ankle and subtalar joint – Monofocal and bifocal
limb reconstruction – Nonunion and bone loss: Monofocal
(compression, neutralization, distraction), bifocal (bone transport,
acute shortening, combined multifocal) – Joint contracture in children
and adults: knee, ankle and foot – Joint distraction: knee, ankle and
foot.
The simple combination of Monolateral Fixation (through its clamp)
and a Ring System results in a hybrid device which provides
cantilever weight bearing, improving the features of other existing
fixators.
The Sheffield fixator consists of reinforced 2/3 and 1/3 rings (the
anterior section is wider or thicker) capable of supporting 2 mm, or
more, wire tensioned to 1,400 Newtons. These rings are used to
stabilize both metaphyseal and diaphyseal segments.
In the metaphyseal segments, wires are attached to the ring through
securing pins and slider units. The metaphyseal ring can be
connected to the diaphyseal ring using threaded bars or reduction
units.
Diaphyseal fixation is achieved with bone screws connected to the
Sheffield clamp in the ring. With the addition of hinge clamps and
threaded bars, the Sheffield fixator can be used for foot and knee
applications. A third ring, fixed with wires or screws, depending on the
location, may be used for complex fracture patterns and limb
reconstruction.
Sheffield Ring Fixator differential features:

Sheffield Hybrid Fixator new philosophy provides maximum bone
support because: Wires are placed in the metaphysis and bone
screws are positioned in the diaphysis; multiplanar fixation is
provided; a minimally invasive procedure is required; an anatomical
reduction can be performed, and early joint movement and immediate
weight bearing are possible.
