Sever’s Disease

Sever’s disease is a common cause of heel pain in children between the ages of 9 and 12 years. The pain is due to calcaneal apophysitis occurring due to repetitive and continuous traction on the calcaneus from the Achilles tendon. The apophysis is not part of a joint and has muscle or tendon attachments. This traction apophysitis may lead to stress fractures, pain and tenderness over the heel.

Sever’s disease is similar to Osgood-schlatter disease of the tibial tubercle.

Patients are usually young athletes presenting with heel pain that increases with activities. Upon examination there could be swelling, tenderness, warmth and/or redness on the back of the heel where the Achilles tendon inserts.

Plain lateral X-rays may show sclerosis or fragmentation of the calcaneal tuberosity. Sclerosis is not specific for this condition.

Fragmentation of the calcaneal tuberosity on the other hand, is more common in patients with Sever’s disease relative to the general population.

Remember that Sever’s disease is a clinical diagnosis. X-rays may show other causes of pain such as tumors, fractures, infections or cysts. MRI is not commonly used, but can help rule out calcaneal stress fractures or osteomyelitis.

Sever’s disease is a self-limiting condition that usually resolves with time. Treatment usually consists of NSAID, Achilles tendon stretching exercises, and activity modifications and in severe condition a short leg walking cast can be used.

Heat Illness in Athletes

As summer approaches, athletes, coaches and other individuals will need to be aware of heat-related illnesses. Heat illnesses include a spectrum of conditions ranging from heat syncope, heat cramps and heat exhaustion to the more severe heat stroke.

Heat Syncope (fainting) is a form of orthostatic hypotension that is related to dehydration. It occurs due to inadequate cardiac output and hypotension. It also occurs with standing quickly after sitting or lying down for prolonged durations in the heat. Symptoms include fainting, dizziness and light-headedness. Treatment includes oral rehydration (water, juice or sports drinks) and placing the patient flat on the ground in a cool area with slight elevation of the legs to push the blood back to the vital organs such as the brain.

Heat Cramps are painful muscle cramps that occur due to decreased sodium heat2.pngconcentration in the blood. The patient’s core temperature is usually not elevated. Sodium may decrease when salts are lost in sweat or with excessive water intake that does not include electrolytes leading to a situation called dilutional hyponatremia. Symptoms include painful muscle cramps occurring commonly in the abdominal muscles, arms, legs and thighs. Treatment includes rest, cooling and IV fluids or oral rehydration with fluids rich in electrolytes (sports drinks and juices) to replenish the sodium stores. Prevention could be achieved by consumption of fluids high in electrolytes before strenuous activities.

heat3Heat Exhaustion is the most common heat illness. The body temperature becomes elevated but is less than 40°C. The core body temperature is best measured rectally. The signs and symptoms of heat exhaustion include profuse sweating, core body temperature lower than 40°C, weakness and fatigue, cramping, headaches, nausea and vomiting,  fainting, hypotension, increased heart rate, and fast shallow breathing. Treatment includes rest, IV fluids or oral rehydration and rapid cooling by whole-body immersion in an ice bath.

Heat Stroke is the most severe form of heat illness. It is a medical emergency that needs immediate attention. The patient should be transported to the hospital as soon as possible. Heat strokes occur due to failure of the body’s normal thermoregulatory mechanism. If treatment is not started promptly, end-organ failure and ultimately death may occur. Heat strokes have a high mortality rate and require quick reduction of the patient’s temperature. The three characteristic features of this condition are a lack of sweating, core body temperature above 40°C (best measured rectally) and an altered mental status. Additional signs and symptoms include hot, dry skin, disorientation, confusion and hallucinations, headache and slurred speech. This is a serious medical emergency that requires rapid core body temperature reduction. The patient should have close monitoring of airway, breathing and circulation. The physician should implement basic life support and ACLS protocols. Rapid cooling by whole-body immersion in an ice bath will be utilized as well as IV fluids.

Marjolin’s Ulcer

Marjolin’s ulcer is a malignant tumor that usually develops into squamous cell sarcoma inside of an osteomyelitis sinus tract.

marjolin3

Fungating soft tissue mass that increases in size and has a foul smell in addition to x-rays that show chronic osteomyelitis that may indicate malignant transformation. It usually takes a long time to develop (about 20 – 30 years).

marjolin2

This tumor usually occurs in the lower extremity and can occur in association with burns, decubitus ulcer and venous ulcer. The skin lesion appears more aggressive with more metastasis (it also can spread to the lymph nodes). There is more recurrence than other types of skin cancers and it is associated with a high mortality rate.

The treatment is usually an amputation. Preservation of the extremity function through a wide resection may not be possible.

Difference between Marjolin’s ulcer and Mandura foot:

Majorlin’s ulcer is a malignant slow growing squamous cell carcinoma that usually develops inside of an osteomyelitis sinus tract. Mandura foot is localized swelling with multiple discharging sinuses (usually fungus). The discharge is grain filled or granular.

Since 1998, Dr. Nabil Ebraheim has served as the chairman of the University of Toledo Medical Center’s Department of Orthopedic Surgery. An involved medical professional, Dr. Nabil Ebraheim maintains memberships with several organizations, including the American Academy of Orthopaedic Surgeons (AAOS).

In its efforts to advance the knowledge and skills of orthopedic surgeons and other members of the medical community, AAOS oversees a variety of musculoskeletal education programs and activities, including webinars and online lectures, live courses, and conferences. The organization’s most popular education offering is the AAOS Annual Meeting, which attracts over 12,000 orthopedic surgeons from around the world each year.

More than 14,500 medical professionals attended the 2016 AAOS Annual Meeting, which was held March 1-5 in Orlando. Over the course of the five-day event, attendees had the opportunity to take part in an education program comprising symposia, lectures, paper presentations, and scientific exhibits on a range of topics. The meeting also featured networking activities and more than 700 technical exhibits showcasing the latest orthopedic products and services.

The next AAOS Annual Meeting will be held March 14-18, 2017, in San Diego. AAOS members can request a packet containing a registration form, housing information, and other details about the event on the AAOS website. For more information, visit www.aaos.org.
