categories of elbow pain and movement dysfunction

1. local neuro/musculoskeletal -anterior elbow: anterior capsule strain, biceps tear/tendonitis, dislocation, pronator syndrome -posterior elbow: olecranon bursitis, triceps tendonitis, posterior impingement, trochlear chondromalacia -medial elbow: medial epicondylitis, UCL injury, ulnar neuritis, flexor/pronator strain, fracture, little league elbow -lateral elbow: fracture, LCL injury, lateral epicondylitis, osteochondral degeneration, radial tunnel syndrome, posterior interosseous nerve syndrome 2. remote/referred neuro/musculoskeletal 3. systemic sources -gout -infective arthritis -polyarthritis - vascular disorders

What are the three main ligaments of the elbow complex? How do ligaments at the elbow complex become injured?

1. ulnar collateral ligament 2. lateral collateral ligament 3. annular ligament -trauma -repeated microfailure (muscle weakness, poor muscle endurance, inefficient movement pattern) -leads to ligament tear/rupture

Gout vs OA

(can look similar) gout: -systemic signs such as fever, chills, warmth at joints/nodules OA: -no systemic signs such as fever and chills, joint pain but redness and warmth not present

lateral epicondylalgia common characteristics

-Age 35-54 -dominant arm - repetitive work/sports/performing arts with gripping or wrist extension -recurrent episodes common -tendinosis of ECRB>ECRL muscle -easy to recognize clinically -underlying pathology is complex

myotomal pattern of weakness

-C5 - rhomboids, supraspinatus -C5,C6 - teres major -C6 - supinator -C6, C7 - coracobrachialis, ECRL, ECRB, FCR, pronator teres, APL -C6, C7, C8 - latissimus dorsi, ECU, EDC, EDM, EPL -C7, C8 - triceps -C7, C8, T1 - FDS -C8, T1 - FCU/FDP, ADP/APB, add pollicis, lumbricals, pronator quadratus, opponens pollicis, opponens DM

self reported outcomes for the elbow

-DASH : disabilities of the arm, shoulder, and hand - quick DASH - ESAS: elbow self-assessment score -PREE: patient rated-elbow evaluation

what are local common sources of pain in the elbow?

-anterior elbow: anterior capsule strain, biceps tear/tendonitis, dislocation, pronator syndrome -posterior elbow: olecranon bursitis, triceps tendonitis, posterior impingement, trochlear chondromalacia -medial elbow: medial epicondylitis, UCL injury, ulnar neuritis, flexor/pronator strain, fracture, little league elbow -lateral elbow: fracture, LCL injury, lateral epicondylitis, osteochondral degeneration, radial tunnel syndrome, posterior interosseous nerve syndrome

subjective interview: specific questions for the elbow

-chief complaint? -how old is the patient? -MOI vs insidious - hand dominance? -history of elbow pain following overuse or repetitive use? -are symptoms related to occupation? -history of locking or catching?

when we think the muscle is a source of pain, what do we do?

-complete a cluster of tests to confirm if the muscle in question is a source of pain 1. stretch the muscle 2. contract the muscle 3. palpate the muscle/tendon

red flags of the elbow

-elbow and arm pain with exertion (cardiac) -other constitutional symptoms that may indicate a systemic cause of symptoms (EX: night pain, night sweats, etc)

how would you assess the integrity of the annular ligament?

-encircles radial head and helps keep the radial attached to the ulna -dislocation in children (common) -look for lump from displaced radial head

inspection of the hand and wrist

-expose full UE: possibility of referral from other sources -posture -attitude of the hand -nails (are they blue/is there a cardiac issue?), skin (shiny, red?), wound/scar

what is tinels sign?

-lightly tap of percuss over median nerve at the level of the carpal tunnel -positive test: sensation of tingling of "pins and needles" distal to the point of percussion. it must reproduce their symptoms to be positive

neuro screen

-need to rule out referral of pain/parasthesias from cervical spine or other regions proximal to the wrist and hand -parasthesias in a peripheral nerve of dermatomal distribution -- which nerve/what level

what is the modified allen test?

-occlude the radial and ulnar arteries at the wrist -exsanguinate the hand by elevation and have patient regularly flex and extend fingers -alternately release the arteries to avaluate sidtsl filling - color should return in 3-5 seconds

what is little league elbow?

-overuse throwing condition in children -excessive valgus stress on tendons/ligaments on medial side of elbow (UCL) - repeated pulling can tear tendon/ligaments away from the bone -called medial epicondylar apophysitis -disrupt growth plate or take a bony fragment with it -disrupt normal bone growth; leads to deformity if ignored

what does the elbow complex do?

-positions the hand in space - transmits power from the shoulder to the hand -ligaments and articulations make it a stable and strong joint -vulnerable to overuse from repetitive activities because it allows little in the way of compensatory adjustments

outline of the subjective and objective info (UE)

-salient features of history - pertinent exam findings - patient goals -your prognosis (time course) -treatment plan -reassessment or change of plan

olecranon bursitis

-superficial tissue -between skin and olecranon process - prolonged weight bearing or direct trauma causes swelling -normally you cant palpate bursa unless swollen

how much elbow flexion is required to perform ADLs?

30-130 elbow flexion

how would you assess the integrity of the lateral collateral ligament?

applu varus stress - in 5-30 degrees of flexion - assess amount of mobility -assess symptom response -compared to uninvolved side

how would you assess the integrity of the ulnar collateral ligaments?

apply valgus stress -in 20-30 degrees flexion -assess amount of mobility -assess symptom response -compared to uninvolved side milking maneuver aims to localize posterior band of UCL -elbow flexed 90 degrees - stabilize humerus -pull supinated forearm laterally on stabilized humerus

from the subjective interview, ________________ sources of elbow pain and movement dysfunction. into what?

categorize -local neuro/musculoskeletal -remote/referred neuro/musculoskeletal -systemic sources

epicondylitis vs epicondylagia

Epicondylitis, or the itis component of that, makes you think that there is an inflammatory component. -Old view -lateral elbow pain -microscopic tears at common extensor tendon -associated with overuse - attempt to heal; healing surface pulled apart with continued use results in inflammation -treatments aimed at reducing inflammation Epicondylalgia is a more general term for lateral or medial elbow pain, pain at the epicondyle -New view -affected tendon lacks inflammatory cells -large number of fibroblasts, disorganiced immature collagen cells, vascular hyperplasia -suggests degenerative process -pain sources: vascular, nerve, neurochemical -also called tendinosis or tendinopathy -similar findings in achilles, patellar, shoulder tendons

Explain why performing wrist extension and radial deviation with the elbow bent biases extensor carpi radialis brevis.

Extensor carpi radialis longus crosses the elbow joint above extensor carpi radialis brevis. Wrist extension and radial deviation with the elbow bent biases extensor carpi radialis brevis over extensor carpi radialis longus. This is a result of an altered length-tension relationship of the muscle based on elbow position.

Name the vascular test that follows the steps below: Compress the radial and ulnar arteries at the wrist. Exsanguinate the hand by elevation, and have the patient regularly flex and extend. Alternately release the arteries to evaluate distal filling. Color should return in 3-5 seconds. Capillary refill test Modified Allen test

distal radioulnar joint

motion resisted = pronation/supination stabilize ulna resting position = 10 supination anterior glide of the radius = pronation posterior glide of the radius = supination

what happens to the tendons when a laceration occurs with an open hand versus a closed hand

open: laceration of skin and tendon occur on the same level closed: when your hand is closed, your tendons glide proximally, therefore if there is a laceration when yous hand is closed, the skin laceration will be proximal to the tendon laceration
