Custom molded orthotics are a device which repositions your feet in a more biomechanically efficient position. The realignment of the muscles, tendons and joints allows the foot to function more efficiently. The realignment takes the stress off the painful, malaligned or damaged tissues.
There are different types of orthotics available. Custom molded structural and functional orthotics and accommodative ones. Structural/functional orthotics reposition and support the foot. Enhance biomechanical control of the foot motions and compensate for malalignment placing the foot in a more stable position and take the stresses off the painful areas of the foot. Accommodative orthotics reduce pressure under painful boney prominences, redistribute forces off of painful areas and give cushioning and minimal realignment of the foot.
After the history and physical examination of the feet and diagnosis is made custom orthotics may be one of the recommended treatment options. Custom orthotics are used for many different medical indications;
Structural – pes planus, pes cavus
Plantar fasciitis/heel spur syndrome
Hallux Abducto Valgus (bunion), Hallux Limitus, Hallux Rigidus
Tendonitis –Achilles, Posterior Tibial Tendonitis
Sinus tarsi syndrome
Tarsal tunnel syndrome
Iliotibial band syndrome
There are many different types of orthotic materials, corrections, modifications and accommodations available for the Podiatrist to choose from. The choices depend on many factors; history, symptoms, diagnosis, what the Podiatrist is trying to achieve, foot type, activity, work, shoe type, weight, foot biomechanics/alignment.
Orthotic shell is made from different materials including; plastics (polypropylene, polynyolene), composite, molds. There are many different cushioning and cover materials available; poron, PPT, neoprene, Spenco, nyplex, P Cell, plastizote, EVA, vinyl, leather, suede. The prescription for orthotics includes the angles/degrees of correction that are measured and put into the orthotics. Also the Podiatrist decides on the heel and forefoot position, arch height, orthotic width and length. For different foot issues different modifications and additions are put into the orthotics. Heel pain would add a heel hole, plantar fasciitis heel and forefoot accommodation, ball of the foot pain a metatarsal pad or bar, Morton’s neuroma a metatarsal pad or neuroma strip pad, Posterior Tibial Tendonitis or Dysfunction a inner arch flare and added material flare, sesamoiditis a dancer’s pad. Specific heel wedging for knee pain.
The various types of custom molded orthotics available are;
There a lot of factors that are taken into account in choosing the right type of orthotic. Orthotics may be one aspect of the treatment plan a Podiatrist can offer. It is recommended to see a Doctor of Podiatric Medicine if one is considering orthotics to get a thorough evaluation, examination, diagnosis and treatment plan.
