Elbow Hyperextension
• Management
– Ice to control bleeding and swelling
– Compression if can tolerate it
– Immobilization – sling and swathe
– Rehabilitation – restore normal motion and
strength
– Taping/bracing – to prevent hyperextension

Lateral Epicondylitis (Tennis Elbow)
• Mechanism
– Repetitive microtrauma to insertion of
extensor muscles on lateral epicondyle
• Signs & Symptoms

• ROM exercises and PRE, deep friction massage, hand grasping while in supination, avoidance of pronation motions
• Mobilization and stretching in pain free ranges
• Use of a counter force or neoprene sleeve

Little League Elbow
– Mechanism
• Caused by repetitive microtraumas that occur from throwing
(not type of pitch)
• May result in numerous disorders of growth in the pitching
elbow
• Linked to:
– Accelerated apophyseal growth region and delay in medial
epicondyle growth plate
– Traction apophysitis with possible fragmentation of medial
epicondylar apophysis
– Avulsion of medial epicondyle or radial head
– Osteochondrosis of humeral capitellum
– Non-union stress fracture of olecranon epiphysis

Little League Elbow
– Signs and Symptoms
• Onset is slow; slight
flexion contracture,
including tight anterior
joint capsule and
weakness in triceps
• Patient may complain of
locking or catching
sensation
• Decreased ROM of
forearm pronation and
supination
![Page 31: Elbow, Hand & Fingersmrburkettscience.weebly.com/uploads/1/4/1/9/... · Little League Elbow –Mechanism • Caused by repetitive microtraumas that occur from throwing (not type of](https://reader033.fdocuments.in/reader033/viewer/2022042321/5f0bcd327e708231d4324884/html5/thumbnails/31.jpg)
Little League Elbow
– Management
• RICE, NSAID’s and
analgesics
• Throwing stops until pain
resolved and full ROM is
regained
• Gentle stretching and triceps
strengthening
• Throwing under supervision
w/ good technique to
prevent recurrence
![Page 32: Elbow, Hand & Fingersmrburkettscience.weebly.com/uploads/1/4/1/9/... · Little League Elbow –Mechanism • Caused by repetitive microtraumas that occur from throwing (not type of](https://reader033.fdocuments.in/reader033/viewer/2022042321/5f0bcd327e708231d4324884/html5/thumbnails/32.jpg)
Elbow Dislocation
– Mechanism
• Caused by foosh w/ elbow extended or severe
twist while flexed
• Bones can be displaced backward, forward, or
laterally
• Distinguishable from fracture because lateral and
medial epicondyles are normally aligned w/ shaft of
humerus

Fingernail Deformities
Changes in appearance of fingernail can
indicate a number of different diseases

• Ridging and poor development = nutritional
deficiencies

heart disorders or chronic respiratory disease
• Spooning or depression = thyroid problems, iron
deficiency anemia
