JOINTS

POLYCENTRIC STANDARD
ACL / PCL / IC

FEATURES
The polycentric joint stabilizes the knee, while adapting to the natural movements of this. Also optimizes the forces of anterior / posterior and varus / valgus stabilization applied by the orthosis.

INDICATIONS
Injuries to the ACL, PCL, Combined Instabilities (CI), MCL and LCL instabilities ligaments.

DropLock LOCK
DEFICIENCY QUADRICEPS

FEATURES
The polycentric joint DropLock has a spring system that automatically locks the joint, when the patient is in full extension.

INDICATIONS
Symptoms or real deficiencies quadriceps, upright support post-polio symptoms.

FourcePoint ™ PROGRESSIVE RESISTANCE
ONLY LCA

FEATURES
Patented joint FourcePoint has a damping mechanism that increases the resistance in the last 25 ° of extension, to reduce the impact of extending and expanding the posterior tibial load.

INDICATIONS
Only clinically proven technology that protects the LCA effectively. It is not indicated for PCL instabilities.

OA CARGO / DESCARGAL
Osteoarthritis

FEATURES
This polycentric joint associated with condylar pad telescopic, allows the patient to control himself loading / unloading brace, 1 ° to 7 °.

INDICATIONS
Suitable for combined unicompartmental osteoarthritis - or not - to instabilities of LCA or LCP or the collateral ligaments (MCL and LCL).

COLORS

Patented System - 4 Points Lever

EachDEFIANCE ®is manufactured and personalized fit for each patient.

Apparatus used to take measurementsDEFIANCE ® patient for orthotics, DEFIANCE ® III, or OA DEFIANCE ®.
The CCMI Mark III can record various anatomical landmarks on the patient's leg, as the degree of varus / valgus, knee angle, the curve of the thigh and calf and their circumferences.

Since 1984, the goal has been DonJoy Orthotics revolutionize technology. By the system "Lever 4 Points" with rigid rings and straps, a further force is applied to the tibia that prevents anterior movement of the same.

UNIQUE SYSTEM INTEGRATION

The center of the orthotic joint is just behind the medial and superior to the anatomic joint line online. This allows items 1 and 3 apply a lever on the femur above sense. Points 2 and 4 move the tibia posteriorly, generating a net differential force or constant load directly on the tibia to prevent anterior movement pathological.

POINT 1
The femur is fixed by a rigid ring in the upper anterior part of the thigh.

POINT 2
The tibia is fixed by a rigid ring on the back and bottom of the calf.

POINT 3
A strap from the rear and lower thigh pushes the femur above.

ITEM 4
A rigid webbing in the anterior tibia applies an active constant load and prevents anterior displacement of the tibia.

FourcePoint ™ Hinge Technology

Faced with intense eccentric quadriceps contractions significant anterior displacement of the tibia which can damage the LCA or permanently lengthen an ACL graft (demorat et al., AJSM, 2004) occurs. Additional studies show that in certain joint angles, particularly in the last 30 degrees of extension, when the voltage is high, the intense activity of the quadriceps should be avoided. DJO has developed a technology to protect the most of LCA and LCA grafts in these positions "at risk".

Small angles of knee flexion at the time of initial contact with the ground in fall activities can injure the ACL. The FourcePoint joint can be used to control the amplitude of motion of the joint as it increases the angle of flexion of the knee during the "fall", resulting in a decrease of between 9% and 13% of the strength of ACL anterior shear (Yu and Garrett, AJSM, 2004).

The DonJoy ® FourcePoint ™ uses a spring mechanism to implement the jointgradually greater resistance during knee extension. The resistance starts in the last 25 degrees of extension (relative to the top of the extension). Adjustments in the joint allow varying degree of resistance to suit the specifications of medical protocol and patient comfort. The joint can also "disabled" or "enabled" to exercise or resistance.

The resistance serves three main functions:

• First, it reduces the length of time the full extent or position "at risk".
• Second, it increases the load applied by the back brace in the tibia to prevent displacement thereof above.
• Third, eliminate the impact of a sudden stop in extent than the patient experience.

The articular FourcePoint ™ technology is used to improve the design of "4 Points Lever" DonJoy to dampen the extent of the knee joint, which improves the mechanical performance of the brace and reduces shear forces the knee. Working with the position "at risk", the strength of the joint is active orthoses in the last 25 degrees of extension.

The FourcePoint ™ along with the set of four "4 Points Lever" joint provides a more comfortable brace that reduces the strength of previous shearr in the knee. The reduction of these forces benefits patients because the pressure on the ACL graft healing phase decreases, which provides stability to an unstable or ACL deficient knee. It can also be used preventively.
