Pin Locking Liners- Advantages & Disadvantages

The following blog post will take a look at the use of pin locking liners.  There are advantages and disadvantages to anything, so we will go from both sides of the issue here when discussing pin locking liners.   For some people, these suspension systems are the only one they would ever consider, for others, another form of prosthetic suspension would be ideal.  Let’s take a look at the following to help you decide for yourself what’s best.

Pin Locking liners allow for the following :
When using a pin locking liner many prosthetic users can indicate that there is a sense of security that comes from the audible feedback that comes from using this system. There are a number of clicks that a person hears when using a pin locking liner to know that they are connected to the prosthesis. This means, from a confidence standpoint, that the prosthetic user knows they are “secure” versus another kind of suspension that feels more complicated to them.  Long time users of pin locking systems may find a sense of comfort with them as well and feel secure because this is the system they have used all along.  Some live by the philosophy, “if its broke, don’t fix it!” Patient’s who are blind, or may suffer from poor eye sight can depend more on these audible clicks to improve use of the prosthesis and their confidence when using it.  There is an obvious benefit to this feedback especially in an eyesight related deficit.

Disadvantages :

Although there are definite upsides to the use of pin locking systems, there are details that a prosthetic user should know (learn about).  While we do not want to discourage you from using a prosthetic pin locking system, we want to be transparent about potential “risks”, however big or small.

The following area list of possible disadvantages that an amputee might face when using a pin locking system:

Stretching of tissue at the end of a person’s residual limb.  The technical description of this would be “distal tissue stretching”.  For example, an amputee can complain of a red mark at the end of their residual limb, or they can even develop sores in extreme circumstances.  This typically a happens in those cases where a person can not feel their residual limb well and they are not monitoring their skin on a regular basis.  Unfortunately, this situation does happen.  This stretching of the tissue has been said to permanently elongate tissue at the end of a persons’ residual limb, regardless if the patient an above knee or below knee amputee.

In our future blogs we will go more toward the “dark side” and point out more features that might not be ideal when using pin locking liners.
