musculoskeletal injuries1
Musculoskeletal Injuries
  • Definition
    • Any injury that occurs to a skeletal muscle, tendon, ligament, joint, or a blood vessel that services skeletal muscle and any related tissues
  • Sport participation
  • Healthy and active lifestyle
long term consequences
Long term consequences
  • majority of these injuries are resolved without significant long-term consequences
short term consequences
Short term consequences
  • Decreased physical strength
  • Nerve impulses slow
  • Circulation and metabolic rates will slow
  • Bone mineral density decreases
  • Collagen level decreases in the connective tissues
  • Reduced cardiorespiratory function
  • Reduced glycogen storage
common causes of musculoskeletal injury
Common causes of musculoskeletal injury
  • Single traumatic event
  • Physical overloads
      • Overtraining
      • repetitive use
frequency of injury occurrence
Frequency of injury occurrence
  • Age
    • Most occur in individuals 15-25 years of age
  • Male vs Female
    • Frequency of the different types of musculoskeletal injuries is relatively equal
    • Different types of specific injuries occurred more frequently due to the physiological differences between men and women
frequency of injury occurrence1
Frequency of injury occurrence
  • 25% of all athletes will expect to sustain a musculoskeletal injury in a 12-month period
  • Higher level athletes have an increased risk for injury d/t greater physical stresses and risks.
frequency of injury occurrence2
Frequency of injury occurrence
  • 25% foot and ankle
  • 22% Knee injuries
  • 11% Back injuries
  • Injuries to the lower leg, thigh, hip, shoulders, and the hand/forearm structure each occur at frequencies of between 5% and 10%
injuries to the musculoskeletal system
Injuries to the Musculoskeletal System
  • Injuries to the musculoskeletal system can be classified according to the body structures that are damaged. Some injuries may involve more than one structure.
4 basic types of musculoskeletal injuries
4 Basic types of musculoskeletal injuries
  • Fractures
  • Dislocation
  • Sprain
  • Strain
common signals of musculoskeletal injuries
Common Signals of Musculoskeletal Injuries
  • Signals of serious injury:
  • Deformity
  • Moderate or severe pain or discomfort, swelling and discoloration
  • Inability to move or use the affected body part
  • Bone fragments protruding from a wound
  • Victim feels bones grating or felt or heard a snap or pop at time of injury
  • Loss of circulation or sensation in an extremity
  • Tingling, cold or bluish color below the site of the injury
  • Cause of the injury that suggests the injury may be severe
  • a medical condition in which there is a break in the continuity of the bone
  • occur when bone cannot withstand outside forces
  • can occur because of direct blows, twisting injuries, or falls
  • a separation of two bones where they meet at a joint.
  • dislocated bone is no longer in its normal position.
  • dislocation may also cause ligament or nerve damage.
  • Causes
  • usually caused by a sudden impact to the joint.
  • usually occurs following a blow, fall, or other trauma.
  • Symptoms
    • Visibly out of place, discolored, or misshapen
    • Limited in movement
    • Swollen or bruised
    • Intensely painful, especially if you try to use the joint or bear weight on it
  • an injury to ligaments
  • caused by a ligament being stretched too far
  • injury to a muscle or tendon
  • can either be a stretching or tear of the muscle or tendon
  • Causes
    • pulling too far on a muscle,
    • pulling a muscle in one direction while it is contracting (called an 'eccentric contraction') in the other direction
    • caused by chronic activities that develop an overstretching of the muscle fibers.
sprain strain
Sprain / Strain
  • Symptoms
    • pain
    • swelling
    • Bruising
    • loss of the ability to move and use the joint
    • instability
sprain strain assessment
Sprain / Strain Assessment
  • Grades
  • commonly graded according to the extent of the injury.
    • Grade I and Grade II
      • usually be treated conservatively with treatments such as icing and physical therapy.
    • Grade III
      • can place individuals at higher risk for permanent instability, and an operation may be a necessary part of treatment.
care for musculoskeletal injuries
Care for Musculoskeletal Injuries
  • Check first for any life-threatening conditions.
  • Call 9-1-1 or the local emergency number if —
  • The injury involves the head, neck or back.
  • The injury impairs walking or breathing.
  • You see or suspect a fracture or dislocation.
  • You see or suspect multiple musculoskeletal injuries.
  • Check for any non-life threatening conditions and care for any other injuries.
general care
General Care
  • The general care for musculoskeletal injuries includes following RICE:
  • Rest
  • Immobilize
  • Cold
  • Elevate
  • If you are unsure whether the injury is serious, care for it as if it is a serious injury.
  • Take steps to minimize shock.
  • Comfort and reassure the victim.
