Carbon Prepreg Orthoses made using the Malmö Technique
Ottobock uses the modern Malmö technique for a custom-made orthosis based on your specifications. Thanks to the combination of flexible and rigid parts, Malmö orthoses can be adapted perfectly to the needs of the user. Ottobock Service Fabrication supports you with precisely fitting leg, knee, and ankle-foot orthoses based on modern prepreg carbon fibre technology.
Advantages of Malmö orthoses:• Graduated thickness of material to optimise
weight and aesthetic appearance• Meet requirements for torsional and bending
stiffness• Optimal stability with low wall thickness• Excellent torsional flexibility• Improved dynamics• Multiple options for fastener flaps, tongues
and pockets• Flexible cuffs, flexible connecting elements
and more flexibility at the seat• Customised forefoot and heel properties
You can also use all knee and ankle joints in our product line for the orthosis design.
IndicationsMalmö orthoses are the ideal solution for many situations. Take advantage of this modern technology, for example for users with the following indications:
• Poliomyelitis• Post-polio syndrome• Neuropathies• Osteoarthritis• Pseudoarthrosis• Spina bifida• Ligament instability• Ruptured cruciate ligaments

Easy to order – Overview of procedure
Make a plaster positive of the affected leg and mark the desired design options on it. Please also fill out the order form.
Use the free pick-up service to send your plaster positive to Ottobock Service Fabrication using the order form (on pages 9/10).
Ottobock Service Fabrication makes your Malmö orthosis within 10 working days and sends it to you afterwards.
You receive an orthosis with an exact fit and optimised material characteristics.
6 Ottobock | Carbon Prepreg Orthoses made using the Malmö Technique
The first steps to the orthosis:Plaster positive and trial orthosis
Your plaster positive is the basis for the Malmö orthosis. Therefore, we would like to assist you with some important tips. For example, remember to cast a metal rod extending at least 10 cm beyond your positive and to shape projections on the positive.
The plaster positive must not be sealed with varnish or covered with thermoplastic padding. We recommend rubber cork as a padding dummy (620P3). Please also make a memory impression of your model, as the sample provided to Service Fabrication may be damaged by heat and pressure during fabrication.
The plaster positive should reproduce the defini-tive position of the orthosis. Mark all the positions of supports, bars, and straps and indicate the individual edge positions.
Particular precision is required for this because the material used in a Malmö orthosis cannot be thermally modified later. We therefore recommend checking the fit with a trial orthosis to determine the exact shape of the final plaster positive. Ottobock Service Fabrication can make the trial orthosis for you. Your patient should try on the trial orthosis without any pad-ding to avoid concealing any potential pressure points.
When you make the plaster positive from the trial orthosis and wish to insert joints, please use the adapter sleeve (743Y48). This gives you a square profile in the positive where the adapters of the joint alignment fixture (743R6) can be inserted.
Padding distance
e.g. 3 mm

And now – options and customised designMark flexible sections such as the forefoot and mould them level. We fabricate the forefoot region using Dyneema coated carbon according to your need for flexibility or stiffness. The tongues and flaps are made of Dyneema, allowing high flexi-bility.
You can simply note extras and comments on the plaster positive. Please mark for example:• Extra padding distances, if needed• Position and size of spacers• Properties of forefoot, heel and springs• All areas for tongues, flaps, and attachmentsfor fasteners.
The surface of the orthosis can also be designed according to your wishes. You can choose from:• Carbon fibre look• Fabric look
The Malmö orthosis: Tips for customised finishingPlease note when providing all information on fabrication and custom design that thermoplastic modification of the orthosis is not possible later. When finishing the orthosis (e.g. grinding or drilling), please ensure that the weight-bearing structures and profile materials are not damaged.
From the positive to the custom designAfter you have made the positive, there are many design options available. They allow you to include the user's individual requirements and demands, for example weight, height, and activity level. Simply use the order form to specify the desired options and then fax it to us.

Shipping to Ottobock Service FabricationPlease pack your plaster positive in a well padded box and send it with the package service of your choice to the Ottobock Service Farbication.
Delivery of your Malmö orthosisOttobock Service Fabrication produces your Malmö orthosis within 10 working days and delievers it to you afterwards.
The Malmö orthosis: finalisation and modifi-cation options after deliveryPlease consider that thermoplastic modification of the orthosis is not possible at a later date. You can grind the orthosis to modify edges but the thickness of the material should not be changed significantly. Cuts or other damage to the surface can lead to weakened areas with an increased risk of breakage. Please also ensure that you do not damage the weight-bearing structures or profile materials when grinding or drilling.
As a final step, you can give the orthosis its individual look and add padding. You can now also add hollow rivets or screws and setting nuts to the fasteners. By applying an outer coating of Pedilin® you ensure that the carbon material does not fray any clothing worn.
The most important criteria for every Malmö orthosis is the user's satisfaction. We wish you success in helping your patient obtain an ideal solution.
