Shin splints refers to shin pain, most commonly with exercise, and can be due to bone, muscle/tendon or vascular issues.
It covers a number of pathologies and is not a specific medical diagnosis.
Imaging, such as MRI, can identify some but not all conditions affecting the area.
For example, it will find bone stress or periosteal reaction. However it can’t detect compartment syndrome.
Each form of imaging has very specific properties and functions, so you should avoid routine screening scans (ie. “Not sure what it is, let’s start with an x-ray”).
Get a specific scan to confirm or exclude the most likely condition in your case AFTER a decent clinical assessment.
Stop shin splints from stopping you!
Identify the pathology
Identifying the specific pathology is vital as the management strategies and activity recommendations are very different.
This doesn’t necessarily mean you need to scan your leg.
A good clinical assessment can confirm the diagnosis by recognising common patterns.
If the pain warms up with activity and gets worse again as you cool down, it’s most likely to be Tibial Periostitis.
Pain that builds with sustained activity and eases within minutes after stopping activity?
You could have Chronic Exertional Compartment Syndrome (NB. don’t get this mixed up with Acute Compartment Syndrome, which is a medical emergency).
Symptoms that worsen with activity, then linger for days afterwards are more likely to be caused by Tibial Bone Stress.
Control the loading
You’ll need to reduce your exercise loading if the pain is worsening, BUT…avoid the temptation to stop altogether.
The underlying causes, such as weakness and stiffness, will worsen with too much time away from exercise.
Gradually reduce your activity each week until it’s at a level that allows your symptoms to improve steadily.
Pain while running
Aim for shorter strides with a faster cadence (steps per minute) to reduce the impact forces on the shin.
That’s not to say that your cadence or stride length were incorrect before.
It’s simply a matter of any reduction in stride length and increase in cadence is associated with reduced impact loading.
Manage the symptoms during and after a run to reduce their impact on your running technique.
Common mistakes when treating shin splints
Fix any deficits identified if they fit with the causative biomechanics
If I had a dollar for everyone given random ankle strength exercises when there was never an ankle strength issue identified in the first place!
Find a cause that makes sense – it might be poor stability or poor technique.
Address that cause directly with an exercise that rehearses the muscle patterns required.
Avoid anti inflammatory meds!
They take away the pain in most cases but they only mask the symptoms while the condition worsens.
They also take away your primary gauge of treatment response.
How do you know an intervention is working if you’re masking the symptoms.
As unpleasant as pain is, it’s great at helping you work out your ideal training load and provides feedback on altered running techniques.
You don’t need to get orthotics or new shoes!!!
Don’t waste your money on new shoes and orthotics UNLESS there’s a proven deficit in your foot and ankle stability that’s contributing to your problem.
Low Dye taping is often used by clinicians to ascertain the effect on improved stability on your symptoms.
It can also be used to temporarily improve stability, if that’s a causative factor.
Here’s a quick video on a simplified Low Dye taping technique you can try at home.
Don’t treat the condition, treat the cause.
The condition is a result of an underlying cause or causes – as long as the cause remains, you’ll have an uphill battle to fix the condition.
Begin to isolate different contributing factors, such as stiffness and stability, so see if they’re contributing to your symptoms.
Don’t try to fix everything at once – it’s impossible to determine what impact a change is having if you’ve changed multiple things simultaneously.
Although it seems quicker to change everything, it’ll slow down your recovery as you don’t know what’s working.
What else could it be?
Conditions referred to as Shin Splints
Firstly, we need to cover what it might be under the generalised heading of Shin Splints:
The most common condition is Tibial Periostitis.
It warms up, even goes away, with exercise. However it worsens on cooling down and with inactivity.
Tibial bone stress injuries present as a bony ache with exercise.
They worsen during exercise and remain sore for days afterwards.
Chronic Exertional Compartment Syndrome is an increase pressure around the calf.
It causes a vague but strong pain in the calf and often has associated numbness or tingling in the foot.
Medial Tibial Stress Syndrome is really a medical name for Shin Splints.
It’s not a specific pathology but is often used to describe a generalised overload pattern of the Tibia as seen on imaging.
Conditions that cause similar symptoms to shin splints
Then there’s a list of conditions which can all cause shin pain but aren’t technically in the Shin Splints category.
Sciatica can cause vague nerve-related pain into the leg, including deep into the calf.
This is often mistaken for calf or shin pathologies as there is often concurrent local issues like sore muscles.
You can also get localised symptoms from a Calf Muscle Strain.
The Soleus muscle, the most commonly injured calf muscle, attaches to the back of the Tibia and can cause shin soreness.
Both types of conditions can cause vague pain into the shin.
