We are presenting a case report of a 10-year-old male with a 1 year history of bilateral heel pain. Sever disease is self limiting condition of calcaneal apophysis. It is the most common cause of heel pain in the growing child. There is no documented case of this condition in this region. This case highlights the clinical features of this self limiting disorder as seen in this patient and reviews the current literature.
A 10 year-old male Kenyan Bantu presented in our clinic with a 1 year history of bilateral heel pain. It had worsened over a two week period and at times he walked on his toes. The pain was of spontaneous onset with no history of trauma. The pain was aggravated by activity and relieved by rest. It was dull in nature and non-radiating. There was no associated history of weight loss, fever or anorexia. There was no past medical history of chronic illness, allergy, hospital admission or surgery. There was no history of similar disease in the family.
Examination revealed a well-nourished boy, not pale, normal skin, normal vital signs. He walked with a limping gait. Examination of the foot revealed marked tenderness at the posterior calcaneus more on the right side.
Investigations done included,
Complete blood cell count-Found normal
Erythrocyte sedimentation rate- 16 mm/hr (normal <20 mm/hr)
Alkaline phosphatase- 95 U/l (normal <270 units/l)
Serum calcium-9.4 mg/dl (normal 8.1-10.4 mg/dl)
Rheumatoid factor- negative
Sever disease also known as calcaneal apophysitis is a common problem in the western world in growing children. There are no reported figures on its occurrence globally. There are no documented cases of this condition in African literature. We consequently present this case found in our region to highlight the features of this disease.
Sever disease was first described in 1912, by James Warren Sever, as an inflammatory injury to the calcaneal apophysis associated with muscle strain in the immature skeleton , It is a nonarticular osteochondrosis of the calcaneal apophysis. It is similar to Osgood-Schlatter disease in the knee and little-leaguer's elbow in the elbow . The inflammatory process is attributed to decreased resistance to shear stress at the bone-growth plate interface . Siffert believed that repeated microtrauma caused mechanical disruption .
Sever disease is the most common cause of heel pain in the growing child. The average age at presentation is 11 years, ranging from 8 to 15 years . In an audit of youth soccer injuries, Sever disease was found to be most common during the beginning of a pubertal growth spurt . A boy-to-girl ratio is 2-3:1. The incidence of bilaterality is approximately 60% . The classical case is usually a preadolescent boy with chronic heel pain. Pain is increased with activity. There no constitutional symptoms. Examination usually reveals no visible abnormalities apart from pain with medial-to-lateral compression of the posterior part of the calcaneus . Toe walking usually relieves pain. The patient may have slightly decreased dorsiflexion due to minimal heel cord tightness. The diagnosis is made purely upon clinical examination .
Plain radiographs do not reveal characteristic features of Sever disease. Ossification irregularities with sclerosis and fragmentation within the apophysis are normal features of a developing calcaneus. The lateral calcaneal view and axial (Harris) view are taken only when the history is not classic, when the patient has night pain, swelling, exquisite tenderness, or when a diagnosis other than Sever disease is suspected . A bone scan may be helpful when a stress fracture is suspected . An MRI can show areas of bone edema and hemorrhage, or a bone bruise, within the metaphyseal bone of the calcaneus .
The laboratory investigations in our case were normal as expected in this condition . The treatment of this disease is non operative . Various modalities have been used including rest, anti-inflammatory medications (NSAIDs), splints and casts. Parents must be reassured that the condition is self limiting and surgery is not an option as a quick remedy. Most cases resolve within months of treatment .
In a child with heel pain, the differential diagnosis may include Achilles tendonitis, retrocalcaneal bursitis, calcaneal stress fractures, calcaneal cysts, osteomyelitis, and plantar fasciitis [7, 8]. Usually, these causes can be ruled out with a well-performed clinical evaluation.
Sever disease is a common condition in the growing child. We present the clinical features of one such case found in our region.
