Lecture 9 - Conditions Of The Elbow & Wrist Flashcards
What is the functional ROM at the elbow?
- Extension to flexion - 0° - 135°
- Pronation to Supination - 70°- 90°
- Hyperextension - 5°
What is the postural observation of the elbow?
- Elbow Flexed: visual formation, isosceles triangle; formed by the olecranon process & the humeral epicondyles
- Elbow Extended: A straight line is formed by the olecranon process & humeral epicondyles
- Carrying Angle: the natural anatomical angle where the forearm points slightly outwards (away from the body) when the elbow is fully extended, typically ranging in Males: 5° & Female: 10°- 15°
What are 2 fractures of the elbow?
- distal humerus
- proximal radius/ulna
What is the MOI of elbow fractures?
- FOOSH or direct impact
- All fractures will result in a great deal of swelling in the area that may often occlude (hide) the actual injury
- There will be extensive pain in the elbow joints
- There will be associated muscle spasm of the surrounding musculature
What is the treatment of elbow fractures?
- Always assess distal MSC
- Splint & support the joints above & below the injury in the most comfortable position available
- Arrange for transport to medical attention
What is volkmann’s ischemic contracture?
- Where a fracture may involve blood vessel & nerve damage, loss of blood flow (4-6 hrs) to the forearm muscles can result in necrosis of the tissue & contracture (hardening) of the muscles
- Deformity is seen with the wrist & the proximal finger joints in extension & the distal finger joints in flexion
What is the MOI of elbow dislocations?
- FOOSH with the elbow forced into hyper-extension (i.e., reaching with arm to brace a fall)
- Severe torsion or varus/valgus force at the elbow when in a flexed position
What is the treatment of elbow dislocations?
- Never try to reduce an elbow dislocation
- Have the individual place the arm in the most comfortable position & apply a splint
- Transport to hospital
What are the complications of elbow dislocations?
- Myositis ossificans (bone tissue forms around muscle) & calcification (calcium build up) of tissue around the joint
- Decreased functional range of motion from scar tissue
- Ulnar nerve entrapment by scar tissue
- Damage to arteries & nerves is always a potential complication
What is the MOI of elbow contusions?
- Direct blow - Very common in athletic activities
- Most often involves the olecranon bursa
What are the signs & symptoms of elbow contusions?
- Very painful
- Rapid swelling if bursa is involved
- Ulnar Neuropraxia with paraesthesia into the ring & baby finger
What is the treatment of elbow contusions?
- PIER, sling support
- Modalities as necessary
- Pad support for return to play
What is the MOI of elbow sprains?
- Valgus or Varus force damaging either ulnar collateral or radial collateral ligament complex
What is the treatment of elbow sprains?
- PIER, rest, sling support, NSAIDS, modalities as necessary
What is epicondylitis?
- inflammation of the epicondyles which are the attachment of the flexor or extensor tendons of the forearm muscles
- causes Tennis Elbow: lateral Epicondylitis & Golfers Elbow: medial Epicondylitis
What is the MOI of epicondylitis?
- Direct trauma
- Overuse & improper mechanics involving wrist movement where there is repeated eccentric loads
What is the treatment of epicondylitis?
- Rest, PIER, Massage (transverse friction), ultrasound, EMS, NSAIDS, support/splint
What are 3 injuries that occur in the elbow from throwing?
- medial tension
- lateral compression
- posterior compression
How do elbow injuries occur when throwing?
- During the acceleration phase of pitching as the humerus is whipped forward there is a great valgus force placed on the trailing bent elbow
- The result is a large tensile load on the medial structures & an equally stressful compression load on the lateral side
What is little league elbow?
- an overuse injury in young athletes, caused by repetitive throwing motions that stress the growth plate on the inside of the elbow
What are the conditions of little league elbow?
- Medial epicondyle epiphysis last to close around the elbow ( susceptible to avulsion injuries)
- Osteochondritis dessecans of the capitulum
- Osteochondrosis of the radial head
What is Colle’s fracture?
- a fracture involving the distal end of the radius, ulna, or both
What is the MOI of Colle’s fracture?
- impact force through an extended or flexed wrist forcing the distal radius & ulna up & back
- Classical sign is a drop down of the hand from the forearm when the arm is held level (Silver Fork or Spoon Deformity)
What is the treatment of Colle’s fracture?
- splint & transport to medical care
