Lower leg prostheses

Amputation below the knee

Prosthetic and orthopedic company "SPTM-ortho M" manufactures leg prostheses for a stump of any length.

Basic information

The design of the lower leg prostheses in our design can be of three types

Our specialists select the complete set of each prosthesis individually, based on your tasks and features. Our goal is to rehabilitate every patient who came to us.

The design of the lower leg prostheses

The modular (endoskeletal) design of the lower leg prosthesis consists of: a stump sleeve (with a soft liner and /or with a silicone cover (liner)), a sleeve adapter (support), a carrier module, a clamp sleeve, a foot module, a cosmetic shell and a cosmetic coating. In turn, the bearing module and the clamping sleeve can be either without or with additional functions of torsion and/or vertical shock absorption. In some designs of clamping bushings, the function of changing the height of the heel can be implemented. The foot modules are very diverse, both in terms of design, appearance, implemented functions, and in terms of price, which gives a chance to almost completely satisfy the needs of even the most sophisticated patients. Some modules of the foot have the ability to adjust the height of the heel.

The modular (endoskeletal) design of the lower leg prosthesis for bathing and water procedures practically does not differ from the usual modular design of the lower leg prosthesis, except that all metal modules are made of corrosion-resistant alloys and have special grooves for removing liquid trapped inside the prosthesis (mainly fresh and saltwater). In this type of lower leg prosthesis, bearing modules and clamping bushings with additional functions are rarely used due to the lack of reliable water-resistant analogues.

The lower leg prosthesis is modular with fastening due to a silicone cover with a distal pin attachment, a hydraulic adapter for stepless heel height adjustment, a carbon foot of an average energy saving level, without cosmetic lining.

The lower leg prosthesis for bathing, with fastening due to a silicone cover with a distal pin attachment, the foot is moisture-resistant with an anti-slip surface, without cosmetic lining.

Components of prostheses

Modular lower leg prostheses consist of several basic elements

01 / 06

The stump sleeve

This is the main element of any prosthesis. It is made exclusively individually, by removing plaster casts from the stump.

02 / 06

The lock

This is a connecting element of a silicone case with a stump sleeve. Locks can be pin, rope, vacuum.

03 / 06

The bearing module

This is a steel or titanium pipe connecting the stump sleeve to the foot.

04 / 06

The foot

This is the supporting element of the prosthesis. The type of foot is selected individually.

05 / 06

Silicone case

It is used to attach the prosthesis. The cover rolls over the stump, and due to its properties, it sits tightly on the stump.

06 / 06

Additional modules

Additional modules can also be used in the prosthesis - a vertical-torsion shock absorber, a heel height regulator.

Taking an impression

ORTO-M uses modern technologies for removing plaster casts

We use modern technology for removing plaster casts. Using a modified high-tech system of hydrostatic crimping of a negative plaster cast with microprocessor automatic adjustment of the pressure.

Hydrostatic crimping systems of negative plaster cast

This technology helps to produce a full-contact stump sleeve with high accuracy, which allows you to distribute the entire weight of the patient's body as evenly as possible over the largest possible surface of the stump, reducing the load on soft tissues.

Preparation of the stump for prosthetics

Immediately after amputation, it is impossible to get a prosthetic, but in each case there should be its own time and its own type of prosthesis. The first thing after discharge from the hospital and removal of stitches is the healing process. Secondly, with the permission of the surgeon who is observing the patient, it is necessary to prepare the stump for prosthetics – to bandage it with an elastic bandage. The time of bandaging is about 2-3 weeks, according to the schedule, it may be more, but less is not effective in our opinion.

The next stage of preparation for prosthetics is "acquaintance" with a silicone case. Patients who come to us for prosthetics receive a case, and stay in it from 3 weeks to 2 months. Firstly, it is necessary to detect a reaction to silicone, and secondly, to change (decrease) the size of the stump. If you make a prosthesis on an unprepared stump, then within a few days of walking on a prosthesis, the stump will get so thin that it will be impossible to walk on a prosthesis and no wool covers will help with this.

The next stage of preparing the lower leg stump for prosthetics is compression therapy with a silicone cover.

If you make a prosthesis on an unprepared stump, then within a few days of walking on a prosthesis, the stump will get so thin that it will be impossible to walk on a prosthesis and no wool covers will help with this.

Bandaging the stump

Before prosthetics, compression therapy with an elastic bandage is recommended.
