Study Notes

Recognizing Sports Injuries

Sports injuries encompass a broad range of conditions
Fractures, dislocations/subluxations, sprains, strains, contusions, nerve injuries, and chronic overuse injuries are among the most prevalent types.

Fractures

Result from extreme stresses and strains on bones
Gross structure of long bones includes diaphysis (shaft), epiphysis (ends), compact bone, articular cartilage, periosteum, and osteoblasts (bone-forming cells).
Classified as open (exposed skin) or closed (no skin break)
Symptoms include deformity, tenderness, swelling, pain with movement
Severity related to applied energy; more complex fractures require more energy.
Healing time depends on the bone involved: long bones (6 weeks), bones in hands & feet (3-4 weeks)

Stress Fractures

Result of overuse, not acute trauma
Commonly occur in weight-bearing bones of the leg or foot
Pain starts as a dull ache, progressively worsening, and becoming worse after activity stops
X-rays might not show the fracture until osteoblasts begin to lay down bone
Athletes should suspend activity for 14 days if a stress fracture is suspected. Return to activity should be gradual.

Dislocations and Subluxations

Dislocation: Complete displacement of a bone in a joint
Subluxation: Partial dislocation where the bones go out of place and back into place
Incidence higher in shoulder, elbow, and fingers
Common in knees (patella)
May result in ligament or tendon rupture
First-time dislocations should be treated as potential fractures.
Immediate reduction isn't always necessary in all cases
A medical professional should be consulted
X-rays are necessary to rule out other potential injuries

Ligament Sprains

Damage to ligaments or joint capsules
Ligaments connect bones
Characteristics of synovial joints include articulating surfaces, articular cartilage, a joint capsule, synovial membrane and synovial fluid, and mechanoreceptors (in muscles, tendons, ligaments, joints) for providing information about joint position.
Sprains classified by severity (Grade I to III), each of which determines the extent of the damage to fibers, instability, pain, and swelling.
Grade 3 sprains often require surgical repair. Rehabilitation is a long process.

Contusions

Caused by external impact pressing against underlying bone
Bleeding into tissues results in skin discoloration (bruising)
Sore to touch
Muscle injuries may be present in active movements and tenderness, with pain usually resolving within a few days; Discoloration typically resolves within a few weeks.
Myositis ossificans: Calcium deposits that can impair movement
Occurs following repeated trauma.

Muscle Strains

A stretch, tear, or rip in a muscle or tendon
Classified by severity: grade I (some fibers stretched or torn), grade II (multiple fibers torn), grade III (complete rupture).
Grade 3 strains often necessitate surgical intervention

Muscle Guarding

Voluntary muscle contractions in response to pain from musculoskeletal injury.
Used to support the affected area or minimize movement
May be mistaken for spasms because increased muscle tone (spasm) is caused by upper motor neuron lesion in the brain

Muscle Cramps

Involuntary contractions in overloaded and fatigued muscle groups
Usually occurs during high-intensity activities

Muscle Soreness

Overexertion in strenuous exercise leading to muscular pain
Occurs in individuals unaccustomed to the activity.
Types of soreness: acute (occurring during and immediately after exercise), delayed onset (DOMS, developing hours or days later), involving muscle pain, swelling, and tenderness.
Treatment: static or PNF stretching and applying ice within the first 48-72 hours after the injury.

Nerve Injuries

Caused by either compression or tension
Types include hypoesthesia (decreased feelings), hyperesthesia (increased feelings), paresthesia (numbness/tingling).
Neuropraxia (“burner” or “stinger”): Trauma to nerves
Neuritis: chronic nerve irritation, often caused by repetitive forces.

Chronic Overuse Injuries

Tendinitis (inflammation of tendons), tendinosis (no inflammation)
Tenosynovitis (inflammation of a tendon and its synovial sheath).
Symptoms for all conditions include pain, swelling, and possibly decreased movement. Treatments often include rest, anti-inflammatory drugs sometimes surgery.
Bursitis (inflammation of bursae, small fluid sacs surrounding joints)
Osteoarthritis (cartilage wearing down).
Myofascial trigger points (painful spots in muscle). Causes can involve mechanical stress, acute muscle strains. Most commonly found in neck, upper back and lower back

Importance of the Healing Process After Injury

The healing process has three phases
- Inflammatory response phase (redness, swelling, tenderness, lasts 2-4 days): essential to healing, cells clean up injury.
- Fibroblastic repair phase (initial scar formation, last 4-6 weeks).
- Maturation-remodeling phase (realignment of scar tissue for joint function, 3+ weeks).
