Broken lower arm or elbow in a cast (Woodcast)

If your lower arm or elbow has fractured we have put it in a cast. You have to use a sling to keep your arm still while it heals.

About your visit

We have examined you and ascertained that you have broken your lower arm or have a fracture in the area around your elbow. Your arm has been bandaged or put in a cast. The cast is made of wood and comes from Woodcast. You have been given a sling to keep your arm immobile while it heals.

If you have been given a cast, it will be removed after ___ weeks, either by your general practitioner or at a check-up at the Ambulatorie for Kirurgi, Ambulatorie 2 (surgical outpatient department).

When you get home

Contact your general practitioner if your condition deteriorates

Call your general practitioner or dial 1813 to reach the medical helpline outside your general practitioner’s opening hours if you experience the following:

  • your fingers become pale, cold or numb
  • your fingers begin to tingle
  • the cast feels too tight or begins to chafe
  • the cast cracks
  • the cast prevents you from doing your exercises
  • there are signs of infection in your arm (fever, heat, redness and a throbbing sensation)
  • the cast gets wet or become loose
  • pain increases.

Take pain-relieving medicine if you are in pain

You should take pain-relieving medicine if you are in pain. Pain relievers can be bought at a pharmacy either over the counter or by prescription. Take only the amount of pain reliever recommended on the package. Contact your general practitioner if you need help managing the pain. Protect the cast when bathing/showering.

Cover your cast with a plastic bag when you are bathing/showering to avoid getting it wet.

The cast can cause irritation

When you have a cast, you will often experience that:

  • you cannot move your wrist
  • your arm becomes sore and tired
  • you sweat under the cast and your skin itches
  • you develop bruises or blood spots under your skin that extend to your fingers.

These symptoms will go away on their own.

If the cast has sharp edges that cause irritation, call the medical hotline on 1813.

Avoid inserting objects to relieve itching

Do not insert objects, such as a knitting needle, under the cast to relieve itching. You risk damaging the skin and causing sores.

Use the sling correctly

Your hand should be elevated above your elbow when wearing the sling. Use the sling on the first day, except at night. If your entire arm is in a cast, use the sling if you are in pain.

Do not wear jewellery on the arm in the cast

Avoid wearing rings on the hand of the arm in the cast as your fingers may swell.

Prevent swelling

To keep your hand from swelling, keep it level with your heart. Rest your arm on a pillow when you are sitting down, for example.

Use your arm while it is in a cast

Move your arm every day, even while wearing a cast. This will help you maintain mobility and avoid swelling. Use your arm as you normally would when dressing, cleaning and eating. Avoid lifting heavy objects, for example grocery bags, for one to two months.


If you need to visit the hospital for a check-up, we will notify you via digital or physical post, or we will call you with information regarding time and place.

If your condition deteriorates before your check-up, contact your general practitioner immediately. If your condition deteriorates acutely, dial 1813 for the medical helpline.


Begin rehabilitation immediately

Start doing the exercises while you are wearing the cast. These exercises will help you regain mobility faster. We will guide you through the exercises.

Complete the exercises four to five times a day and repeat each exercise at least 15 times. Relax your shoulders and keep an easy pace.

If you begin to feel pain while doing the exercises, take a 30 minute break and then continue doing the exercises. Remove your sling when you are doing the exercises.

Worth knowing

We will assess whether you need to be examined for osteoporosis (brittle bones)

If the fracture could be due to osteoporosis, you will be referred to your general practitioner for an examination. In some cases, you will also have blood tests taken. Osteoporosis is easy to treat, and treatment will reduce the risk of more fractures.
