Blatchford Javelin Instructions D'utilisation page 2

1 Description and Purpose
Application
These instructions are for the practitioner.
The term device is used throughout these instructions for use to refer to Javelin.
This device is to be used exclusively as part of a lower limb prosthesis.
A lightweight, high-energy-return foot, ideal for medium impact use. The flexible extended pylon
reduces shock load transmission making it suitable for work and leisure activities. Independent
heel and toe springs provide some axial deflection. The split toe provides good ground
compliance.
This device is recommended for users that have the potential to achieve Activity Level 3.
Of course there are exceptions and in our recommendation we want to allow for unique,
individual circumstances. There may also be a number of users in the Activity Levels 2 and 4*
who would benefit from the smoother transition from heel to toe offered by this device, but this
decision should be made with sound and thorough justification.
*Maximum user weight 100 kg and always use one higher spring rate category than shown in the
Spring set selection table.
To minimise the risk of slipping and tripping, appropriate footwear that fits
securely onto the footshell must be used at all times.
Contra-indications
This device might not be suitable for Activity Level 1 individuals or for competitive sports events,
as these types of users will be better served by a specially designed prosthesis optimized for their
needs.
Intended for a single user.
Ensure that the user has understood all instructions for use, drawing particular attention to the
section regarding maintenance.

Activity Level 3
Has the ability or potential for ambulation with variable cadence.
Typical of the community ambulator who has the ability to traverse most
environmental barriers and may have vocational, therapeutic, or exercise activity
that demands prosthetic utilization beyond simple locomotion.
Note:
If in doubt choosing between two categories, choose the higher rate spring set.
Foot Spring set recommendations shown are for transtibial users.
For transfemoral users we suggest selecting a spring set one category lower,
refer to fitting advice Section 9 to ensure satisfactory function and range of movement
