CANCANEAL APOPHYSITIS (SEVER’S DISEASE)

This is painful inflammation of a child’s growth plate at the heel.  Normally, this affects children between 8 – 14 years old as their calcaneus (heel bone) is still developing.  It is also at a time when children often increase the amount of exercise they do.  With increased and repetitive use, the achilles tendon ‘tractions’ on the growth plate at the heel and so causing pain and inflammation.  Approximately 60% of Sever’s is bilateral.

Causes

It is essentially an overuse injury at the time of growth.  Sports that ‘load’ the achilles tendon and heel such as running and jumping are normally the culprits.  Often a bout of Sever’s can become aggravated at the start of a season after a ‘rest’ period or exercising on harder ground as it gets colder.  Tightness in the calf can also lead to increased load onto the heel bone.  It bad cases, it may take until the child stops growing before complete resolution.  It is also really important to try to observe why there has been more load placed onto their heel… this may be from a stiff hip or other area.  This is key to successful treatment.

Diagnosis

This needs to be based on a full and correct examination by your osteopath, doctor or other medical professional.   X-ray or MRI may be used to confirm the diagnosis or monitor the progress, but often this is not necessary.

Treatment

Calcaneal apophysitis has no known long-term complications and is self-limiting; that is, it should go away when the two parts of bony growth eventually join together (occurring around 16 years of age).

It is important to limit (temporarily) excessive or rigorous activity in its painful stages.  But it is also about management, as you can get times when it calms and at other times, it can then flare up again as they increase activity.  Soft shoes and heel cups can make a difference and it is important to make sure the child has sound biomechanics (eg no excessive pronation or muscular imbalance). Regular and correct stretching of the tight muscles in the calf and thigh are essential.   Ice can be of great help if used correctly.  Anti inflammatory medication may be of use – but do check with your medical professional about this first.

Seeking help from your osteopath or good physical therapist can really help too.  They will check for poor biomechanics and work and stretch the calf and thigh and manage this injury with some good strengthening exercises.

Return to sports or activity

The goal here is to get your child back to their desired sport or activity as soon as safely possible.  It may be a gradual return to see if the condition regresses.  If they return too early, it may lead to more chronic pain.

To return to sport your child should have no pain at rest and should be able to walk pain free.  They should also be able to jog, sprint and hop pretty much symptom free too.

If after the pain resolves…. it is important that there is still a regime of regular stretching of their calves, thigh and leg muscles.
