What are Shin Splints?
Shin Splints are the common name for a condition in which the muscles on top of the shin bones – the tibia and the fibula, become tight and as a result cause pain.
It mostly occurs after an increase in activity – either frequency, length or intensity, and can last for an undetermined amount of time depending on various factors such as exercise, rest and strength.
Medial Tibial Stress Syndrome:
Medically, shin splints are referred to as Medial Tibial Stress Syndrome (MTSS). It is caused by overuse and is commonly seen in athletes and military personnel. The cause of MTSS is not known however many factors can cause it including overtraining, poor unsupportive footwear, ankle muscle imbalance, tight triceps surae muscles (calf/soleus) and your back being out of balance.
Typically MTSS presents with a diffuse (wide spread) palpable pain worse after exercise – it is more common in females than males. The pain is usually described as a dull ache that gets better with rest. One reason MTSS is so painful is due to periostitis – the inflammation of the periosteum (covering of the bone) where the muscle attaches.
Specific movements that may cause pain is knee extension – that is the straightening of the leg, as this activated the muscles affected. Inflammation of the Achilles tendon (Achilles tendonitis), the bursa on the back of the heel (retrocalcaneal bursitis), plantar fasciitis (irritation of the plantar fascia), medial arch discomfort, calf pain and cramping, iliotibial band syndrome and Osgood Schlatter’s can also occur at the same time as MTSS.
One of the risks of having MTSS repeatedly or long term is a stress fracture. Signs this has occurred is when pain occurs after activity has finished into cooldown and daily activities. Another sign is when the pain becomes less wide spread and more specific to the inside of the tibia (shin bone) and the from halfway up the shin down after exercise. Imaging such as x-ray and magnetic resonance imaging (MRI) can be used to detect other sources of pain as well as stress fractures.
Treatment:
Treatment of MTSS varies depending on therapist and sport. In the acute, short-term treatment use of compression stockings, anti-inflammatories, rest and either ice or heat depending on the varied evidence. Kinesiology taping uses tape that aims to relieve pain, facilitate proprioception, change muscle activation and correct abnormal movement patterns.
Long term orthotics (inserts) and supportive shoes can be used to try and correct the posture of the foot. Increasing the supination (weight on the outside of the foot), strength of the inverter/evertor muscles and releasing the muscles on the bottom of the foot can also be helpful. Supplements such as vitamin D, calcium for bone health/density and magnesium for muscle fatigue should be taken long term as preventatives.
Manual therapy, such as osteopathy can be beneficial in both the short and long term phases of shin splints/MTSS. Through various techniques such as soft tissue, myofascial release, mobilisation and manipulation treatment is aimed at decreasing muscle tension, improving joint mobility and releasing the fascia of the foot and lower leg.
