Elbow Complex Flashcards
What are norms for carrying angle?
male- 11-14
female 13-16
What ligaments are on medial side of elbow?
Ulnar collateral
anterior- taught in extension
posterior- taught in flexion
What are ligaments of lateral elbow?
RCL- taught throughout ROM
lateral UCL- primary restraint to valgus stress
What is the annular ligament?
stabilizes proximal radiounar joint
anterior taught with supination
posterior with pronation
Where does the radial nerve pass in the elbow?
anterior to lateral epi, innervates extensor supinator group
Where does the ulnar nerve pass in the elbow?
posterior to medial epicondyle
innervates FCU
What does the median nerve innervate?
flexor pronator group
What is typical mechanism for elbow instability?
FOOSH
What is patient presentation for elbow dislocation?
nerve complaints s/p traumatic event
What is difference between simple and complex dislocation?
simple- soft tissue injury, no fx
complex- multiple articulations and fx
What is simple dislocation management?
stable- immediate AROM if pain free, compression and gripping
unstable- immobilize (not more than 14 days) pronation/supination for stability strength
What is immobilization protocol for complex dislocation?
immobilized at 90 for 0-10 days post op
When can AROM begin for complex dislocation?
10-15 days post op
What is a supracondylar fracture?
50% of elbow fractures in kids, FOOSH
either a closed reduction or ORIF
What is a olecranon fracture?
common in elderly, presents with disruption to tricep function and displaced intra articular jt fracture
What are complications from olecranon fx surgery?
loss of extension, ulnar neuropathy, postraumatic arthritis, instability
What is radial head fracture?
common in females 20-60 y/o usually from blow to pronated arm, direct blow to elbow, hyper flexion during an injury
What is management of a radial head fx?
type 1- early motion
type 2-4- immobilize in full extension and surgery
When is a radial head excision indicated?
intact UCL required, strong flexor pronators and if unable to fix bone
strength will be decreased after post surgery
When is a radial head replacement indicated?
type 4 fracture, UCL or RCL dysfnx and instability, coronoid fracture
What is rehab for excision or replacement?
immediate ROM
What is difference from primary and secondary elbow OA?
1- degenerative
2- prior trauma
What is patient presentation for primary elbow OA?
40-60 males, usually repetitive use laborers with insidious onset
sx: end range pain, loss of extension, painful locking
What is patient presentation for secondary elbow OA?
any age or gender, prior trauma or surgery
SX: s/p trauma and same as primary
