Handling Measurement Discrepancies or Socket Sizing Issues

When you send us both a scan and measurements, it's likely they won't be 100% spot on. We'll dive into how to navigate those situations and how to get your measurements closer to your scan. This article will also highlight your options if your sockets are regularly coming out too big or too small for your patients.

Measurement Discrepancy Handling

How would you like to handle measurement discrepancies as they arise, and how can you prevent discrepancies?

1. On the order form, you'll see a field for "Measurement Discrepancy Handling," so we can help keep the sizing as accurate as possible to your expectations. This asks if you'd prefer we:

• Set the size to your measurements
• Set the size to the scan measurements
• Reach out to verify differences larger than +/- 7 mm.

2. If you regularly have a large measurement discrepancy, you may consider:

• Taking measurements differently. Measurements on the looser side tend to match up better to the scan.
• Calibrating your structure sensor. If you're using a scanner with an iPad, you can learn how to recalibrate here.

Socket Sizing Issues

If your sockets are coming out too big or too small for your patient, below are a few things to keep in mind.

1. Has your patient size fluctuated?

• Take a measurement before ordering your socket and at the socket fitting. This will tell you if the patient fluctuated or if we need to work on socket sizing.

2. How are you taking your measurements?

• Are you taking tight or loose measurements, and does that correspond to whether the socket is too tight or too loose?
• Did you provide AP and ML measurements? We usually only use these as a reference, but these numbers can be instrumental in ensuring we keep sizing accurate.
• If there is an issue with length, are you taking it axially or contour to the limb?

3. What kind of preferences have you given us?

• We typically build a design profile for each clinician, with individual preferences on reliefs and reductions. We may need to take a closer look at what modifications we're applying and if we need to be more or less aggressive with them

Getting the sizing right is a learning curve between you, the technology, and your design lead. If you have any questions about how your sizing has been coming out, contact us below to schedule a check-in call with your design lead!
