Introducing the 4-Hole Base Plate

In 2014 we successfully launched LIM Innovations® Infinite Socket™ TF, fitting over 1500 patients along the way. To celebrate, we are adding to the current Infinite Socket™TF components with the introduction of the 4-hole base plate.

“Our job is to invent on behalf of our users, and we only move forward with creating products that significantly improve their experience,” states Jeremy Galten, LIM Innovations’ SVP of Product. Galten continues, “The new base plate design, which no longer incorporates the pinch bolt, provides even greater security for the patient while providing clinicians maximum flexibility when connecting components.”

The four-hole base plate allows the clinician to find the optimal offset for limb length and alignment through the built-in line of progression. It continues to offer 5 mm of radial slide and 40º of angular pivot per strut. The 4-hole base plate has been also been designed to maximize structural integrity enhancing peace of mind for both the clinician and the patient.

The technical aspects of the base plate family, which comes in four shapes and sizes are broken down below.

Angular alignment built in (degrees) Posterior offset of knee with respect to socket (mm) Lateral offset of knee with respect to socket (mm)
  0 0 0
  0 22 0
  0 30 20
  15 60 20


The 4-hole base plate will be available on all new orders submitted after May 1st.

Driven by Data

Carol Davis was fit with a highly custom socket to address the lack of comfort and motivation that had left her without a leg for over a year. She always looks above and beyond the past, and with the help of data, her progression in recent months has been nothing far from astonishing. Read what Carol had to say.


“I wanted to thank you guys again for constructing a wonderful adjustable and easy to put on socket. I know my residual limb was a challenging fit with a pediatric circumference, long length, and fragile skin. It’s so amazing as I had been out of a leg for over a year, and now I am up walking a couple of miles a day, working in the garden outside, and spending time with my grandkids. My favorite activity however is spending time with my husband going on walks near the beach.

Thank you also for the Fitbit™! I love being able to track my steps, active minutes, how many stairs I climb, and how much energy I am exerting per step. I think everyone could benefit from having this on their leg. The first day I put the tracker on it was pretty late in the day and I logged 250 steps; not a lot, but in the grand scheme of things to come it was a step in the right direction. The first week I took around 1,500 steps a day and that has increased from there. I now regularly have been doing over 6,000 steps a day and have approximately 40 minutes of active or sustained walking. It challenges me to keep moving and do more. Recently, I was able to do a 5K fun run/walk at our 4th of July event. In case you are interested, my Fitbit™ showed that it was over 8,000 steps and 88 minutes of constant movement! Thank you for giving me a life back!

Please keep on doing what you are doing. I hope that the data device gets added to all of your new sockets. The socket works well, providing comfort in an adjustable fashion. Understanding the data that I generate on a daily basis keeps me moving forward, setting new goals to achieve rather than just sitting around. When you see progress it is easier to stay motivated, and for that I will always be grateful.”

Introducing the Pin Lock

Two years ago we successfully fit our first Infinite Socket.
To celebrate, we are adding to the current Infinite Socket suspension line with the introduction of the pin lock.

We are excited to expand our product line, to include all three major suspension options. The pin lock provides a light and reliable option for amputees. It consists of a drawdown clutch-lock and cushioned end-pad, easing the donning procedure, minimizing pistoning and rotation, and providing a secure fit.

The pin lock interfaces with a locking liner to engage the patients residual limb. The liner is placed into the distal end of the socket, and can be tightened down with the shuttle-lock, located on the medial side of the prosthesis. The prosthesis will remain securely engaged, and can only be released if the patient presses the shuttle-lock.

Helping 200 amputees find more comfort

It’s been a year since shipping the first Infinite Socket and I’m proud to announce that 200 amputees are using LIM to walk comfortably and with greater control than before.

200 people is just a start for LIM. Afterall, there are an estimated 2 million people living with limb loss in the U.S. and 40 million internationally. But for us, this milestone demonstrates what we’ve only dreamed could be true: To develop a better prosthetic socket that enables amputees to live beyond their injuries and to get more from life.

We love what we do because everyday we talk to people who are searching for a better prosthetic limb and we can help them. One person at a time and each with their own story. As a result, there’s a lot of joy happening at LIM in 2015 and we’re all looking forward to helping more and more people in the year to come.

Thanks and happy holidays.

Seeing Miyah happy and living an active lifestyle in her LIM socket is what inspires our team to keep innovating. At three years old, she’s already overcome more adversity than most and we’re excited to see her grow up with the chance to do whatever she puts her mind to. Miyah and her prosthetist, Brent at Eastpoint Prosthetics and Orthotics, are  helping spur an evolution from the outdated and outsized medical devices currently used with children to a brand new era of pint-sized versions tailored for kids’s needs. We couldn’t be more proud to be a part of that.

WASHINGTON (AP) — Improvise isn’t a word parents want to hear from their kid’s doctor. Yet pediatric specialists too often have to jury-rig care because many of the medical devices needed to treat sick children were built for adults.

A birth defect left Miyah Williams with one leg missing at mid-thigh. The prosthetic leg she received as a toddler came with such a painful, sweat- and sore-inducing socket; a rigid cup connecting the leg to her thigh that she refused to wear it. Part of the problem is size. Now families are starting to demand solutions to address the issue and rightly so.

Photogrammetry: Turning photos into 3D scans

Here at LIM Innovations we pride ourselves on the diversity of our team. We have a fantastic group of engineers, designers, machinists, clinicians, and amputees with relevant experience in the field. With such a diverse group working behind the scenes, we invite you to join one of our staff members each week for an in-depth look at what they bring to table. It is our goal to provide our loyal reader’s a behind-the-scenes look at LIM Innovations. Jesse Williams, Chief Technology Officer, picks up the pen this week to discuss photogrammetry with your cell phone and free software.

You can use any camera including your cell phone to make a great 3D image. The process is called photogrammetry, and it’s awesome. You should try it right after reading this blog. The software you need is free!

To do this, you need to take pictures of the object at many different angles. Usually you need 20 to 60 photos to make a great scan. This may sound like a lot, but with most modern cell phones, you can continuously take pictures if you hold down the capture button. When I do this, I hold down the capture button, and walk around the image. In about 45 seconds, I can capture up to 100 images. Once the images are taken, special software can convert them to a 3D scan. The process is called photogrammetry. The software recognizes patterns in the photos, and find the same patterns in different photos. Then uses a triangulation process to understand the position each photo was taken at. On a side note, triangulation is the way GPS location works. Anyway, once the software knows the positions of the photo it can understand the 3D shape in the photos, and generate the 3D model.

There are several different software packages available to do this, and they can range in price from free to very expensive. I use the software developed by Autodesk, and they have three different iterations. The oldest is called 123D Catch. I’ve had okay results with this program. Next they developed ReCap, short for Reality Capture. This is a free program that runs completely online in your web browser. This program works very well. Lastly, Autodesk is in the process of developing Project Momento, and you can download the beta version for free here. This program works like magic. Both Recap and Momento use the Autodesk servers to process the photos and convert them to the 3D model, and in my experience, this can take from 30 minutes to 4 hours (there is some serious processing going on here). Autodesk will then email you when the process is done.

Below you can see a scan of Luigi, a little guy my wife made for me years ago. (He’s definitely seen better times.) Here’s one of the pictures used in the scan (I’m using a Moto X cellphone).


I took 86 images in about 20 seconds to make this 3D scan using Project Memento. 86 images is overkill, but it’s easy just to hold down the capture button and take a lot of images.

You can see that Lughi looks good but the edges of the image don’t because my photos centered on Lughi. In the next images shows the polygons that make up the 3D image.

There are some tricks to getting a good result: glare on the object will kill it, the photos shouldn’t be blurry, and there should be enough photos, and the object should take up most of the photo. Also, there is no way the software knows scale in the image, so if size is important you will need a reference object in the image to calibrate it.

It is possible use photogrammetry to generate 3D scans of patients residual limbs. We can make the patient customized Infinite Socket from this data. While this process is not officially supported, I would be happy to work LIM Specialist to test this data capturing technique. If you are interested in trying it out, please email me.
