IntroductionHistoryClinical EvaluationSpecial InvestigationsThree stage assessmentProblem list formulationPlan and ProgressionDiscussion
TABLE OF CONTENTS
26 y.o. male, rugby player – backline
Plays rugby for fun, not very fit
Bank clerk
Smoker & social drinker
No chronic medical conditions
INTRODUCTION
Came of rugby field during pre-season practiceIntense pain – over both lower legsStarted gradually during running exerciseHas to stop running for relieveFlared up with increased exercise intensityPrevious h/o ‘shin-splints’
HISTORY
Tenderness over post.med. borders – both tibiasMiddle 3rd of tibias – most tendernessPain – passive ankle dorsiflexionPain – plantar flexion against resistancePain – ‘toe raises’Pain – 4-5 single leg hopsHyperpronation – both feet
CLINICAL EVALUATION
None indicated
None done
SPECIAL INVESTIGATIONS
1. Clinical Medial Tibial Stress Syndrome (Shin Splints) Brought on – intense & repetitive running
exercises
2. Personal Concerned – he frequently has to stop running
or exercise – severe leg pain
THREE STAGE SUMMARY
3. SocialAfraid – miss out on team selectionFriends – ‘sissy’, for quitting exercise
THREE STAGE SUMMARY
1. Active Painful lower legs – Medial Tibial Stress
Syndrome (Shin Splints)
2. Passive Preventing him from completing training
sessions & matches General fitness deteriated
PROBLEM LIST FORMULATION
Iced lower legs – initiallyAnalgesiaRecommended – 10 days rest from runningRefer – innersoles to improve hyperpronationPhysiotherapy
Still in rest period & awaiting innersoles
PLAN AND PROGRESSION
DefinitionMedial Tibial Stress Syndrome (MTSS) is defined as pain along the posteromedial border of the tibia that occurs during exercise, excluding pain from ischaemic origin or signs of stress fracture (Newman and Adams 2012).
DISCUSSION
MTSS – one of the most common causes of exercise-related leg pain
Running & walking activities – most frequently16.8% long distance runners35% - military academies USAFemales twice the risk then menMiddle third mostly, then lower third of tibia
DISCUSSION
Unclear (many theories)Periostitis (inflammation of the periosteum) Tearing of the muscle bone interface
Soleus m, tibialis post & flex digi longus – culpritsStress reaction of the bone (tibia)
PATHOPHYSIOLOGY OF MTSS
History
Patients often c/o painPosteromedial border of tibiaDistal 2/3 of tibiaDuring running activities
Increase in running intensity
Change of running surface
CLINICAL PICTURE
Tenderness over 4 – 6 cm areaPost.med border, middle & distal thirds of tibia
Provocative tests for MTSS
pain with:Passive ankle dorsiflexionResisted plantar flexionToe raises4 – 5 single leg hops
CLINICAL EXAMINATION
abrupt increase in training activitiesinadequate shoeshard or inclined running surfacesprevious MTSSfemale genderincreased BMI
RISK FACTORS FOR MTSS
increased foot pronationincreased varus tendency of the forefoot and/or
hind foothip internal or external rotationincreased muscular strength of plantar flexors
RISK FACTORS FOR MTSS (2)
Stress fractures of the tibia – caused by repetitive loading with resulting microfracture
Chronic exertional Compartment syndrome – is a condition of increased pressure in the fascial compartments of the leg
DIFFERENTIAL DIAGNOSIS
Peripheral Nerve entrapment – most often caused by trauma, the common peroneal, superficial peroneal and saphenous nerves are most commonly at risk for entrapment
Popliteal artery entrapment syndrome – is an uncommon
overuse injury, frequently caused by compression of the popliteal artery by surrounding musculotendinous structures as it exits the popliteal fossa
(Brewer and Gregory 2012)
DIFFERENTIAL DIAGNOSIS (2)
X-rays – rarely positive early on. X-rays performed 2 to 3 weeks after onset of pain may reveal periosteal reaction or a radiolucent line (stress fracture)
Radio isotopic bone scan – can confirm the presence of
MTSS or a stress fracture MRI scan – is the investigation of choice for lower leg pain MRI arteriograph – can confirm popliteal artery syndrome
SPECIAL INVESTIGATIONS
Rest for 7 to 10 days from painful activitiesIcingAnalgesia for pain relieveStretching of calf musculatureStrengthening of calf musculatureActivity modification Orthotics or inner soles to correct foot
hyperpronation
TREATMENT OPTIONS
Extracorporeal Shock Wave Therapy (ESWT) – is a new treatment modality for MTSS. Rompe et al (2010) used low-energy ESWT to treat MTSS. After 15 months 76% of the treatment group were able to return to their sport symptom free, compared to only 37% of the control group. This study showed that low-energy ESWT is safe and effective to treat MTSS
TREATMENT MODALITIES (2)
Bisphosphonates (currently used for treatment of osteoporosis) – Moen at el (2011) administered bisphosphonates to two athletes diagnosed with chronic MTSS. Both athletes returned to their sport in a much shorter time. These case reports raise the possibility that bisphosphonates could decrease the time to return to sport in MTSS patients.
Surgery – only for very severe cases of shin splints that do not respond to conservative treatment. However the effectiveness of surgery remains unclear.
TREATMENT MODALITIES (3)
Shock-absorbent insoles Pronation control insoles (specifically controlling
navicular drop) Graduated running programs
Correcting training errors: – like an abrupt increase in training activity -Changing to a harder training surface
PREVENTION MEASURES
Abruptly increasing training activities, changing running surfaces and inadequate shoes – ‘shin splints’, correcting these factors and rest are important to manage the condition.
