The foot has 3 arches

A

fyi

30
Q

Susceptible to a variety of injuries, which range from muscle strains and ligament sprains to dislocations and fractures.
Most common injury is an ?

A

ankle sprain

31
Q
  • Mechanism of Injury is usually a combination of excessive inversion and plantar flexion
  • More than 80% are this type
A

Ankle Sprain

32
Q

The most injured ligament in an ankle sprain is What?

A

anterior talo-fibular ligament (ATF)

note:Other ligaments involved in an inversion sprain are the calcaneofibular and posterior talofibular ligament

33
Q

Less common ankle sprain is the eversion sprain
Which ligament helps prevent excessive eversion?

A

The deltoid ligament

34
Q

ankle sprains are Usually placed into one of three categories: what are they?

A
  1. first (mild)
  2. second (moderate)
  3. third (severe)
35
Q

Surrounding tissues are stretched with minor discomfort, point tenderness and little or no swelling.

what category of ankle sprain?

A

First (Mild)

36
Q
  • One or more portions of the ligaments is torn with pain, swelling, point tenderness, disability and loss of function
  • Slight, abnormal movement in the joint

What category of ankle sprain?

A

Second (Moderate)

37
Q
  • One or more ligaments have been completely ruptured or torn resulting in joint instability
  • An accompanying fracture is possible

What category of ankle sprain?

A

Third (Severe)

38
Q
  • Each arch of the foot contributes to balance, movement, support and shock absorption
  • Any of the arches (transverse, medial longitudinal or lateral longitudinal) can suffer supportive ligament sprains
  • Once the ligaments are stretched, they fail to hold the bones of the foot in position
  • Once the arch is weakened, it cannot absorb shock as well as it normally does

what type of sprain?

A

Arch Sprains

39
Q

Causes of an arch sprain include:

A

overuse, overweight, fatigue, training on hard surfaces and wearing unsupportive shoes

40
Q
  • Occur at any part of the body where there is friction, most commonly found on the feet
  • As layers of the skin rub together, friction causes separation
  • Fluid creates pressure on nerve endings, which is perceived as pain
  • If neglected, it may break and create an open wound
A

Blisters

41
Q
  • Great toe is very important in balance, movement and speed
  • Occasionally, ligaments of the toe will become sprained, severely limiting the athlete’s performance
  • Also called “Turf Toe” and mechanism of injury is the foot sliding backwards on a slippery surface
  • Forcefully causing hyperextension of the big toe

what type of sprain?

A

Great Toe Sprain

42
Q
  • is a wide, non-elastic ligamentous tissue that extends from the anterior portion of the calcaneous to the heads of the metatarsals, supporting the longitudinal arch of the foot
  • Tissue can become strained from overuse, unsupportive footwear, a tight achilles tendon, or running on hard surfaces
A

Plantar Fasciitis

43
Q

what’s the most common cause of Plantar Fasciitis?

A

chronic irritation

  • Running
  • Jumping and landing
44
Q

What are S/S of Plantar Fasciitis

A

Pain with palpation near the heel or on the bottom of the foot

45
Q

If Plantar Fasciitisis left untreated it can lead?

A

to heel spurs, muscle sprains, shin splints and other problems

46
Q
  • The heel receives, absorbs and transfers much of the impact from activity, especially running and jumping
  • Ligaments, tendons and fat pad of the heel are all subject to stress and injury
  • A _________ _________ is among the most disabling contusions one can receive
  • The heel must be well protected during physical activity
A

Heel Bruise

47
Q
  • A bony growth on the calcaneus that causes painful inflammation of the accompanying soft tissue
  • Often aggravated by exercise and activity
  • As the foot flattens, the plantar fascia is stretched and pulled at the point where it attaches to the calcaneus
  • Over time, the calcaneus responds by forming a spur of bony material over the heel
A

Heel Spur

48
Q
  • Occur mostly over the shin as the tibia lies just below the skin and is very sensitive to direct trauma
  • Can also involve muscular areas of the leg
  • Complications can include swelling in compartments and can lead to compartment syndrome
  • Can also lead to damaging the peroneal nerve
  • Can result in loss of function to the dorsiflexors and everters of the foot, known as drop foot
A

Contusions

49
Q
  • Frequent and powerful use of leg muscles commonly result in injury
  • Can occur anywhere along the muscles and normally result from a violent contraction, overstretching or continued overuse
  • The most common of leg strains occur to the calf muscles
  • Can result from repetitive overuse or a single violent contraction
A

Strains

50
Q
  • Sudden, involuntary contraction of a muscle
  • Can be caused by many factors such as
  • Fatigue – working a muscle beyond its limits
  • Fractures – after a fracture has healed, muscles tend to atrophy. If muscles are not strengthened appropriately, cramps may occur
  • Dehydration – lack of fluids can cause muscle cramps
  • Lack of nutrients – may lead to an electrolyte imbalance, causing muscles to cramp
  • Poor flexibility – muscles may be worked beyond its limits
  • Improperly fitting equipment – may cause excessive strain, resulting in breakdown
A

Muscle Cramps

51
Q
  • A painful condition caused by inflammation of the Achilles tendon (can occur anywhere along the entire length of the tendon)
  • Reflects tearing of the tendon tissues caused by excessive stress
  • Injury can occur by a single incident of overstressing, or it can occur from an accumulation of smaller stresses that produce numerous small tears over time
  • Often occurs at the point where the tendon attaches to the heel
A

Achilles Tendonitis

52
Q
  • Signs and Symptoms:
  • Symptoms develop gradually and discomfort may be relatively minor at first and worsen if the patient tries to “work through” the pain
  • Initial discomfort is often attributed to the aches and pains that accompany fatigue
  • Pain
  • Crepitus upon palpation
  • Redness at the site of discomfort
A

Achilles Tendonitis

53
Q

Occur within the tendon substance itself, approximately one to two inches proximal to the insertion of the tendon into the calcaneus
Causes include poor conditioning, over exertion and antibiotic use
Ruptures usually occur as the result of direct trauma and must be surgically repaired

A

Achilles Tendon Rupture

54
Q
  • Catch-all term for pain that occurs below the knee either on the front outside part of the leg (anterior shin splints) or on the inside of the leg (medial shin splints)
  • Appears to be associated with repetitive activity on hard surfaces or forcible excessive use of the leg muscles, especially with running and jumping activities
A

Medial Tibial Stress Syndrome (Shin Splints)

55
Q

Can be caused by a variety of things:
Tightness of the gastrocnemius and soleus muscles
Running on hard or uneven surfaces, which places a greater force on the lower leg complex
Worn or ill-fitting shoes that increase the stress on the leg muscles
People that run primarily on their toes place a tremendous amount of stress on the anterior portion of the leg
People who overpronate when running cause the muscles of the foot and leg to overwork in the attempt to stabilize to pronated foot

A

Medial Tibial Stress Syndrome (Shin Splints)

56
Q

Pain in the lower leg can be disguised as shin splints but can actually be a ______ _________
Described as an incomplete crack in the bone, which is a far more serious injury than shin splints
Microscopic fractures/deteriorations in the bone will lead to a full fracture if left untreated
Bone scan is the definitive tool for diagnosing a stress fracture

A

Stress Fractures

57
Q

Signs and Symptoms:
Palpation of a “hot spot” of sharp/intense pain notes a possibility of a _______ ________
Typically feels better in the morning because the bone rested all evening where as shin splints are worse in the morning because the soft tissue tightens overnight

A

Stress Fractures

58
Q

Swelling within one or more of the four compartments of the lower leg
Anterior compartment
Peroneal compartment
Deep posterior compartment
Superficial posterior compartment
May be caused by contusions, fractures, crush injuries, localized infection, excessive exercise or overstretching

A

Compartment Syndrome

59
Q

Signs and Symptoms:
Point tenderness and pain in the affected muscle group
In later stages of compartment syndrome, you might see numbness, weakness, inability to use the defined muscle group
Must be diagnosed immediately or irreversible neurological, muscular or vascular damage can occur
Delay will result in permanent disability

A

Compartment Syndrome

60
Q

Tibia and fibula are susceptible to fractures associated with athletic activity
Both bones are vulnerable because they are close to the surface and force directly impacts the bone as there is little soft tissue for protection around them
10-15% of all fractures in the lower leg are open fractures, in which the bone protrudes out of the skin
Diagnosed by x-ray for confirmation of a fracture as sometimes, patients are able to ambulate

A

Fractures
