Supinators

Changes in the joints of the foot inevitably lead to disruption of its normal biomechanics; occurrence of local overload zones; disruption of the support, pressor and balancing functions. In these cases, changing the relationship in the foot-support system can help by using various orthopedic corrective devices, most often insoles supinators are used.

Foot joint damage is one of the most common orthopedic problems in rheumatology practice. 90% of patients with rheumatoid arthritis have foot damage. In osteoarthrosis, damage to the first metatarsophalangeal joint is the third most common after knee and hip joint pathology.

In addition, the foot is the base of the entire musculoskeletal system, plays a key role in the distribution of dynamic loads in all other links. The establishment of the dependence of the distribution of dynamic loads between the lateral and medial condyles of the tibia on the position of the foot served as a prerequisite for the use of insoles with a raised lateral edge in patients with medial gonarthrosis.

A difference in the length of the limbs of more than one centimeter can be one of the causes of pain in the lower back. In these cases, an important pathogenetic treatment measure is compensation of the length of the shortened limb with an orthosis.

What are insoles with arch supports for?

Insoles-supinators improve the function of the foot due to uniform redistribution of static and dynamic loads, eliminate zones of local overloads (especially in the area of the heads of the metatarsal bones), set it in a neutral position, reduce excessive pronation in the subtalar joint during rolling, restoration of the spring function. Compensation of the difference in the length of the lower limbs, redistribution of loads between the condyles of the tibia in medial gonarthrosis occurs. Insoles-supinators help in the prevention of recurrence of deformations after reconstructive operations on the foot and ankle joint in patients with rheumatological diseases.

Indications and contraindications

Deformation of the forefoot (hallux valgus, hallux rigidus, hammertoe, subluxation of the metatarsophalangeal joints); metatarsalgia; flat or hollow stola; plantar fasciitis; heel spur; medial gonarthrosis; conditions after reconstructive operations on the foot and ankle.

There are no contraindications.

How to choose insoles with arch supports?

To correctly select orthotic tactics, a thorough assessment of the condition and function of the foot is necessary using radiographic, podometric, plantographic and, if possible, podographic methods.

As in other groups of orthoses, there are two approaches: orthotics using standard factory blanks or individual production of insoles. The use of standard semi-finished and finished products is possible if the foot dimensions correspond to the parameters of factory models. However, pronounced foot deformities are a contraindication for the use of standard orthoses (hypercorrection can aggravate the pathological condition). To make a plaster model for individual production, both the unloaded and loaded (preferably) methods of obtaining a negative impression of the foot are used.

Effect

Pain reduction and improvement of walking parameters. The use of insoles in patients with gonarthrosis reduces the need for NSAIDs. The preventive role of foot orthoses has not been studied.

Factors affecting efficiency. Selection in strict accordance with individual parameters of the foot and features of functional disorders.

Complications

If the insoles of the insoles are not selected correctly (do not match the relief of the foot), the pain when walking may increase, abrasions and calluses may occur. In this case, its use should be stopped immediately and seek help from a specialist.

Alternative methods

Use of special orthopedic shoes. If insoles and arch supports are ineffective, surgical treatment is used.
