🎨 Why Buy Direct from OrthoTape?
Most doctor's offices stock only 2–3 basic cast colors because they don't want to manage large inventories. That means you're often stuck with white or beige — for a cast you'll wear for weeks. OrthoTape offers 16+ colors at a fraction of what clinics charge. Same professional-grade materials. Your color. Your choice. Many patients bring their OrthoTape kit to their appointment — doctors are happy to use it. You can also purchase this kit for your midterm cast change and save significantly on the materials cost.

💬 Frequently Asked Questions
What is a long arm cast and when is it used?
A long arm cast (also called a full arm cast) immobilizes the elbow, forearm, and wrist in a single rigid cast. It is most commonly used for a broken humerus (upper arm bone), elbow fractures, and forearm fractures where the elbow must be kept still to allow proper healing. The cast typically holds the elbow at a 90-degree angle.
How long do you wear a long arm cast for a broken humerus?
Most patients wear a long arm cast for a broken humerus for 6 to 8 weeks, depending on the severity of the fracture, the patient's age, and the treating physician's protocol. Children often heal faster than adults. Your orthopedic surgeon will monitor healing with X-rays and determine when the cast can be removed or transitioned to a shorter cast or brace.
What is the difference between a long arm cast and a short arm cast?
A long arm cast (full arm cast) extends from the upper arm or just below the shoulder down to the palm, immobilizing the elbow. A short arm cast only covers the forearm and wrist, leaving the elbow free. Long arm casts are required when the elbow joint must be immobilized — such as with humerus fractures, elbow fractures, or certain forearm fractures.
Can I bring my own cast kit to my doctor's appointment?
Yes — many patients bring their OrthoTape kit to their appointment. Doctors are generally happy to use patient-supplied materials, and you'll save money on the casting materials portion of your visit. It's best to have your kit in hand 1–2 days before your appointment. Order by 2 PM EST for same-day shipping.
Is this kit FSA or HSA eligible?
Yes. OrthoTape casting supplies are FSA/HSA eligible medical products. HCPCS code A4570 applies to casting supplies. Check with your plan administrator for specific coverage details.

This is a top of the line boot. I have used another brand given to me by my doctors office that that had a lip on the outside not padded which created skin breakdown on the out side of my foot. The form fit design does not have a lip and has more rubber padding at the sides than the competitor. I showed the difference in engineering design to my doctor and highly recommended the form fit boot. Please
Note they were the same price.
So, I finally got the opportunity to use the casting tape today. I want to preface this by saying I'm not a professional caster.
The tape seemed to dry out a bit too fast (it was a bit of a hot day, but I used cold tap water. As a result, the layers didn't seem to mold together very well. However, that may have more to do with MY lack of experience.
The one complaint is that the hot pink had some light (almost white) spots in the roll, and a strange waffle pattern in the ends of the rolls.
Hi Alan, thanks for sharing your experience. The white spots are caused by the dry gloves touching the casting tape. Usually when I do a final layer, I do not touch the tape at all except for the sides, so I get the perfect color finish. As for the honeycomb at the end. In our next batch we are changing that center so it does not do that. Usally I cut it off with scissors before that. As for drying out, that has to do with how fast you are at casting. Since you said you were new at it, that can happen as you have to work quickly with the tape before it hardens. You will get better with more practice. Also make sure your bucket is a new bucket, a household cleaning bucket can have cleaning residue which can cause issue with the polyurethane resin.
I have used in the past and it is great! Best advice is that it stretches more so get a size smaller than you think. But it’s a lifesaver in pediatrics!!
Hi Ericca, thank you for your wonderful feedback! If you like Delta Dry, try our OrthoH2O we are happy to send some samples to you. It is a much easier one piece application. It does not tear easy like Delta Dry and it is much more cost effective. See it here or search OrthoH2O on our site: https://orthotape.com/collections/orthoh2o-waterproof-cast
