Notes from our Certified Fitters:
Always contact your physician and or therapist to determine the correct compression strength for your condition.

Traditionally the treatment of choice for healing venous ulcers has been firm, non-elastic bandages, but results from a scientific study has shown the Sigvaris UlceRx Therapy Solution to provide an alternative, superior option to using bandages for wound care, including improved comfort and reduced pain.

This dual-stocking system consists of a low-compression underliner with approximately 10mmHg compression strength and an over-stocking of 30-40mmHg to provide a combined ankle pressure of 40-50mmHg.

The underliner keeps the dressing in place at night, helping patients to rest more comfortably. It should be worn during sleep and while recumbent. During daily activities the over-stocking provides the necessary compression needed to heal the venous ulcer.

Care Instructions:

Measuring for Sigvaris Compression Stockings:

It is recommended that you mark the leg with a non-permanent, non-toxic marker at each circumference measurement made.

General Guidelines

  • Measurements should always be taken as soon as possible after waking when swelling is minimum
  • Measure next to bare skin
  • The measuring system is based on having the foot flat against the floor and the leg at a right angle to the foot
  • Measurements must be taken by pulling the tape snugly around the leg but without constriction
  • Measurements should be taken from the ground up

Measuring Instructions for Knee High (Calf) Style

1. Measure the ankle circumference at the narrowest part of the ankle, above the ankle bone. Use the appropriate series sizing chart to determine if ankle is Small, Medium, Large, or X-Large.
This should be your first measurement.

2. Measure the calf circumference at the fullest part of the calf.

3. Determine the calf length by measuring from the floor up to the bend of the knee. This measurement is taken on the outside of the calf.

Measuring Instructions for Thigh High and Pantyhose Styles

1. Measure the ankle circumference at the narrowest part of the ankle, above the ankle bone. Use the appropriate series sizing chart to determine if ankle is Small, Medium, or Large.
This should be your first measurement.

2. Measure the calf circumference at the fullest part of the calf.

3. Measure the thigh at the widest circumference.

4. Determine the thigh length by measuring from the floor up to the gluteal fold.

About Leg Health:

Many factors contribute to the overall health of our legs: heredity, weight, age, diet and activity level. But it's the internal function of the legs that also plays an important role: calf muscles, arteries, veins, and vein valves--the internal highway of blood and oxygen flow.

Your Circulation:
The flow of blood in the veins is assisted by a series of one-way valves. The valves remain open when the blood flows toward the heart, and then closed after blood passes through. Over time, an increase in pressure can stretch the vein walls. If a vein becomes enlarged and over-stretched the valves cannot close properly, causing blood to leak back down into the lower legs, resulting in poor circulation.

If this happens you may begin to develop symptoms, such as:

  • Heavy, tired, aching legs
  • Swollen legs and/or ankles
  • Sensation of warmth in the legs
  • Tingling or cramping of the legs
  • Dull or sharp pain in the calf
  • Small varicose veins and spider veins

Using Compression Therapy:
Graduated compression stockings and socks are important to leg health. They help minimize muscle aches, swelling, and symptoms of fatigue. Exercise and a healthy lifestyle will strengthen your legs, but wearing graduated compression stockings or socks will support the internal function of the veins.

The Sigvaris UlceRx Therapy Kit includes an over-stocking which is the open toe 30-40mmHg knee high of the 500 Natural Rubber Series. The 500 Series has a large selection of unisex open toe styles for both men and women in knee high, thigh high with and without Grip-Top and with waist attachment option, and pantyhose. The 500 Series is designed for people with more serious indications or long-term therapy and is uniquely made from double-covered, soft, natural rubber to offer the greatest degree of elasticity while maintaining a sustained compression throughout the day. Their low fatigue rate makes them ideal for the person who must always wear compression stockings, and the porous, high-stretch knit construction as well as the double-covered yarns allow easy donning and removal.

We recommend that donning gloves always be worn when applying your compression garments. These gloves have a gripping texture that makes it considerably easier to put on compression hose. Donning gloves also help to prevent tearing, snagging or putting a nail or finger through the garment. Other people prefer to use a donning aid like the Juzo Slippie Gator or Jobst Stocking Donner.

We also recommend either Sigvaris, Juzo, or Jobst Jolastic Special Washing Solutions for maintaining the quality of compression garments. Jobst Jolastic Wash is formulated to remove oil, body acids, and skin salts quickly and easily without damage to the fabric. This specially designed solution will help extend the life of all elastic garments. The ingredients in Jobst ensure excellent soil removal and are mild to the user's hands.

Midtown Health offers a large selection of many widely recognized and respected brands of compression socks, stockings, and other garments that fit every lifestyle and medical condition in many different styles and compression strengths.

Jobst Vairox provides effective leg therapy for severe indications such as pronounced varicosities, chronic venous insufficiency, postphlebitic syndrome, edema, lymphedema, orthostatic hypotension, post-surgery sclerotherapy, and venous ulcers. Vairox is designed for precise fit in a zippered style for easier donning and to guarantee 30-40 compression for optimum medical efficacy while the multifiber yarns yield a softer feel. The reciprocated and reinforced heel allows for greater durability and lasting comfort.

The New Jobst¬ UlcerCARE Zippered Stocking and Liner are designed for maximum patient compliance. Designed specifically to help manage venous leg ulcers, UlcerCARE gives you freedom from weekly bandaging visits. The Jobst¬ UlcerCARE provides a graduated compression of 40 mmHg and is created with a high stiffness factor to provide the optimal compression. The liner is coated with a silk material for ease of putting on and taking off. Common footwear and clothing may be worn to provide a normal lifestyle. The new zipper version improves the process for easy donning. The zipper is available on the left or ride of the leg which allows for comfort and ease of closure on the opposite side of the wound. Each stocking comes with 2 liners.
