Specific Sport Injuries Flashcards
Why is a lateral ankle sprain more prevalent than medial ankle sprain
Weaker ligaments
Fibula acts as a mechanical barrier
Most people land in an inverted foot position
Lateral ankle sprain is what percentage of all sporting injuries
10-15%
Injury sequence of a lateral ankle sprain
Anterior talofibular ligament
Calcaneofibular ligament
Posterior talofibular ligament
Muscluotendinous units supporting the ankle joint
Stress fracture
Hairline or microscopic break in bone due to repetitive stress rather than trauma
Stress fracture risk factors and symptoms
Inadequate shock absorption, sudden increase in training, nutrition factors are all among risk as well as it being more common in post menopausal women.
There is pain and swelling at locality, pain at rest, can be diagnosed via a bone scan, a stress reaction may proceed, takes 6-8 weeks for the bone the heal
Achilles’ tendon bursitis
Repeated trauma/ friction causing inflammation of the bursa
Tendocaneal- irritated by shoes especially heal
Retrocaneal- irritated by calcaneous and/ or tendon
Causes pain in back of heels when running, wearing shoes or swelling
Cannot use massage but heel raise, Ice, shoe change if acute and a bursa resection if it is chronic
Plantar faciitis (muscle under foot is the plantar fascia)- causes
Inflamation caused by excessive stretching of the plantar fascia
Caused by overpronation (flat feet), reduced range in Dorsi flexion, sudden increase in activity, excessive weight, improper fitting footwear.
Plantar fasciitis symptoms
Stiffness and pain first thing in the morning
Pain upon direct pressure over site of disfunction
Pain upstairs, on tiptoes or standing for long periods
Pain sometimes lessons as exercise continues
Associated tightness if achillies and gastrocnemius
Achilles tendonitis and causes
Chronic micro tears to Achilles tendon by repetitive activity
Caused by overuse, chronic increase in training, unaccustomed activities, overpronation, excessive tension into dorsiflexion
Symptoms of Achilles tendonitis
Pain upon palpating Pain on tendon during exercise Possible creaking/ crepitus upon movement Pain and stiffness in the morning Pain when walking upstairs
What are Shin splints
Generic complain for pain in the shin area, stress fracture, compartment syndrome, medial tibial stress syndrome, periostitis of medial tibia due to attachment of soleus and it contracting eccentrically
Causes of shin splints
Overpronation
Sudden increase in training
Running in spikes and forefoot strikers and hard surfaces
Sports with repeated landing and taking off
Insufficient warmup
Tight soleus muscles
Compartment syndrome- and acute vs chronic
When the muscle becomes too big for the fascia that surrounds it
Acute compartment syndrome is a medical emergency but we can treat chronic compartment syndrome with a hands on technique
Acute- trauma, 3rd degree tear, fractures
Chronic- hypertrophy, venous/ arterial blood supply impaired, hypoxia causing pain on hard surfaces
Symptoms of compartment syndrome
Sharp pain in muscles Weakness, sensory loss, lack of pulse Swelling and tenderness Pain during exercise and goes at rest Difficulty in plantar and Dorsi flexion
Causes of ACL
Lateral blow
Trauma forcing femur backwards
External rotation and valgus strain
PCL sprain causes
Hypertension
Falling on tibial tuberosity
Trauma forcing tibia backwards
