FAQ

1. What does “DEN” mean in stockings? Do they indicate compression strength?

DEN or denier expresses the strength of the textile fibre used to manufacture stockings. The higher the number, the stronger and less transparent the product. Technically, denier a is the length weight of fibre – indicates how many grams weighs 9 kilometres of the yarn used.

In medical products, the compression power is always indicated by words or acronym CCL with the value of a mercury column (in mmHg – millimetres of a mercury column). The classification into compression classes is governed by the German RAL GZ 387 standard. A detailed distribution of socks into compression classes by pressure at the ankle is shown in the table.

Manufacturer's note: For the convenience of customers, our lines are marked with numbers where higher numbers indicated stronger compression, such as in Avicenum 70, Avicenum 140, Avicenum 310, Avicenum 360, and Avicenum 520.

2. The lace or hem of my thigh-high stockings does not hold. What can I do about it?

Medical stockings are manufactured by strict production standards where all input materials must meet the highest criteria. We know from experience that the causes of poor adhesion of silicone laces or hems are these:

• The patient wears the stockings on the legs after applying a cream to them.
  Advice: Degrease the leg at least in the area of the lace or hem, for example using suitable rubbing alcohol.
• The patient washes the stockings using a softener.
  Advice: We recommend you wash your stockings in hands in soapy water. Softeners impairs the function of the silicone elements. To restore their functionality, use an alcohol-based solution (e.g., rubbing alcohol).
• The patient purchased an incorrect size of the stockings.
  Advice: Whenever you are buying compression stockings, always make sure you properly measured your legs and selected the correct size! There are special “minus” sizes for individuals with slim thighs and “plus” sizes for those with thicker thighs. Consult your doctor or vendor of medical products.
• The patient has very hairy thighs.
  Advice: There is no easy advice in this case. Such patients should either shave a strip on the thigh under the lace or hem or use suspender belts.

3. What is the correct size of medical compression stockings?

Compression stockings are a medical product designed to prevent and treat the circulatory system and therefore it is necessary to select its correct size.

Avicenum PHLEBO 40 / Avicenum PHLEBO 70 sizes – support compression class (standard sizes)

• calf-length stockings sizes are selected by the size of the feet: 36–38 (23–25), 39–41 (25–27), 42–44 (27–29), 45–47 (29–31)
• sizes of thigh-high stockings:
  M, L (thigh circumference 50–60 cm)
  XL (thigh circumference over 60 cm)
• tights sizes are selected by the body height / hip circumference

Avicenum 140 sizes – compression class 1 (circumference and length of the legs)

• to correctly determine the size of the calf-length or thigh-high stockings and thighs, it is necessary to measure both the foot circumference at several measuring points and the length of the leg
• then select the correct size from the Avicenum 140 size table depending on the measured values

Avicenum 310 sizes – compression class 1 (standard sizes)

• calf-length stockings sizes are determined by standard sizes for feet 36–38, 39–41, 42–44, 45–47

Avicenum 360 and Avicenum 520 sizes – compression class 2 and 3 (measurement of the circumference and length of the legs)

• to correctly determine the size of the calf-length or thigh-high stockings and thighs, it is necessary to measure both the foot circumference at several measuring points and the length of the leg.
• then select the correct size from the size table
• in addition to the standard and special sizes, there are also minus (for patients with slim thighs), plus (for patients with thicker thighs), and ultra-short (for small patients) sizes.
• patients with non-standard or non-symmetrical (left vs. right limbs) can order custom-made compression products
