Tarsal Tunnel Syndrome

Tarsal tunnel syndrome is a condition that is caused by compression of the tibial nerve or its branches.

Tarsal tunnel syndrome is analogous to carpal tunnel syndrome of the wrist.

The tarsal tunnel is a narrow space that lies on the inside of the ankle.

The tunnel is covered with a thick ligament called the flexor retinaculum.

Structures within the tarsal tunnel include:
-Arteries
-Veins
-Tendons
-Nerves

Tarsal tunnel syndrome is a compression on the posterior tibial nerve.
This syndrome produces symptoms anywhere along the path of the nerve.

Possible symptoms include:

-Tingling
-Burning
-Numbness
-Shooting pain
-Paresthesias

Contribute Factors to Tarsal Tunnel:
-Soft tissue masses:
Lipomas-is a benign tumor composed of fatty tissue
-Tendon Sheath Ganglia:
Neoplasms- is an abnormal mass of tissue as a result abnormal proliferation of cells
-Nerve tumors
-Varicose Veins

Work up:

Tinel sign- Percussion of a nerve with radiation of pain along the course of the nerve.

The doctor may order any of the following tests to help with the diagnosis:
-Electromyography (EMG) - A technique for evaluating and recording the electrical activity produced by skeletal muscles
-Nerve conduction velocity (NCV)
-Magnetic resonance imaging (MRI)- In cases of suspected soft-tissue masses and other space-occupying lesions
-Ultrasonography
-Radiography

Conservative Treatment:

-Rest
-Ice
-Non steroidal anti-inflammatory drugs-to help reduce pain and inflammation
-Immobilization- Restricting movement of the foot by wearing a cast or cam boot
-Physical therapy
-Injection therapy
-Orthotic devices. To control any abnormal bio mechanics of the foot








-Surgical Therapy

Tarsal tunnel release surgical intervention may be needed if conservative therapy fails to alleviate pain and symptoms. This procedure is used to decrease pressure on the posterior tibial nerve. Any space occupying lesions may also be excised.

Psoriasis

Psoriasis is a common, chronic, relapsing, inflammatory skin disorder. Psoriasis has a genetic basis and can affect the skin the nails and also joints.

Psoriasis has a tendency to wax and wane.

Flares can be related to systemic, environmental factors, or infection.





Psoriasis most commonly manifests itself on the skin of the elbows, knees, scalp, and lumbosacral areas.



Most psoriatic nail disease occurs in people with clinically evident psoriasis.


Psoriatic arthritis is a chronic inflammatory arthritis that is commonly associated with psoriasis.



Frequency

Approximately 2-3% of people are affected by psoriasis

At least 5% of patients with psoriasis develop psoriatic arthritis

Sex

Psoriasis is slightly more common in women than in men


Symptoms of Psoriasis

The surface of psoriatic lesions often has a layer of dead skin cells that appear as silver scales.

Erythematous(Red) scaly area which can have a sudden onset.

Scaling plaques that itch.

Lesions may be vesicular.

Joint Pain.



Joint Findings

Sausage Digits

Enthesopathy- An inflammation of the insertion points of tendon into bone.

Tendonitis

Nail Findings

Oil drop - a translucent, yellow-red discoloration in the nail bed resembling a drop of oil beneath the nail plate.


Pitting- Pitting is a result of the loss of cells from the surface of the nail plate.


Beau lines- These lines are transverse lines in the nails


Leukonychia- Leukonychia is areas of white nail plate.


Onycholysis Onycholysis is a separation of the nail plate from its attachment to the nail bed.



Causes


Psoriatic lesions are caused by an increase in the skin cells turnover rate.

Genetic factors- Approximately 40% of patients with psoriasis or psoriatic arthritis have first-degree relatives who are affected.

Psoriatic nail disease may be due to a combination of genetic, environmental, and immune factors.



Differentials

• Seborrheic dermatitis
• Onychomycosis
• Squamous cell carcinoma
• Nummular eczema
• Lichen planus
• Lichen simplex chronicus
• Pustular eruptions

Arthritic Differentials

• Gout
• Osteoarthritis
• Rheumatoid arthritis
• Septic arthritis

Work Up


Radiographs of affected joints can be help differentiate the type of arthritis.

Psoriatic arthritis- The diagnosis is based primarily on clinical and radiographic findings.

Nail biopsy- A nail biopsy may be obtained to confirm the diagnosis of nail psoriasis



Laboratory studies

Rheumatoid factor (RF)- negative

Erythrocyte sedimentation rate (ESR)- usually normal

Uric acid level- May be elevated in psoriasis





Treatment

Skin Lesions

Topical corticosteroids- Used to reduce plaque formation.


Coal tar- Coal tar is an inexpensive treatment that is available over the counter in shampoos or lotions for use in widespread areas of involvement..

Keratolytic agents- Used to remove scale, to smooth the skin, and to treat hyperkeratosis


Psoriatic arthritis

Nonsteroidal anti-inflammatory drugs- (NSAIDs)

Disease-modifying antirheumatic drugs (DMARDs)

Anti–tumor necrosis factor (TNF)-alpha medications.

Nails
Avulsion therapy -can be used as an alternative therapy for psoriatic nail disease.

Shoes that are creating their own path in our world: Part 2

Simple Shoes

This shoe company has come along way since opening in 1991. The Simple shoes that we know and love today are not at all the same shoes from the 90’s. For about 13 years Simple was just like every other shoe company out there. But in 2004 Simple Shoes had an epiphany and decided to take on the challenge of providing eco friendly shoes to the public. They started small with 2 different styles in 2005 called their ‘Green Toe’ collection. These shoes where a hit and as soon as the ball was rolling for Simple there was no stopping it. Over the past few years Simple has produced with even more shoes that incorporate natural and sustainable materials into their products. In 2006, Simple set a new goal to become a 100% sustainable company. This was a huge step for any company, and a very exciting one at that. In 2007, they took it one step further (we didn’t think it was possible!). Simple shoes started to use recycled materials as well as products found naturally in our world. So now, old tires can gather dirt on people’s feet instead of in a dump. To learn more about Simple Shoes visit http://www.simpleshoes.com/.

Shoes that are creating their own path in our world: Part 1

Tom’s

Tom’s are extremely colorful with many different patterns, but this is just a bonus. The best thing about these shoes is that you get two for the price of one! Deals are great aren’t they!! What is even better about this deal is that one pair of shoes goes to you and one pair of shoes goes to a child who doesn’t have any shoes to call their own. Tom’s was started in 2006 by Blake Mycoskie. His inspiration came from seeing children without shoes on his visit to Argentina. A little known fact is that many diseases can be picked up from the ground by being absorbed through the skin on the feet. Another concern is puncture wounds especially when medical treatment is not readily available. These things are not acceptable when there is something we can do about them. So, when Blake came back to the states he got very busy. During his first year in business he gave 10,000 shoes to children all around the world. Tom’s have become increasingly popular over the years. Their expansion has been exciting and inspiring. As of April 2010, Tom’s have given approximately 600,000 shoes to children all over the world! To check out Tom’s shoes online please visit www.toms.com.

Take Me Out To The Ballgame

For over one hundred and fifty years, Americans have been devoted to the game of baseball as both fans and participants. With the arrival of each spring, thousands of people across the country search for their gloves and cleats in preparation for the upcoming baseball and softball season.

Spring also brings an influx of patients to the local emergency rooms and doctor’s offices because of the injuries associated with our national pastime. Before you ever step up to the plate, take the time to ensure that you are actually ready to run the bases. Read more about baseball and your feet in my new article Baseball and Your Feet.
