Orthopedics Flashcards
Transverse fracture
Right angle to the axis of the bone
Spiral fracture
Has twisted appearance, also called otrsion
Oblique fracture
Fracture line between horizontal and vertical direction
Comminuted fracture
Splintered or crushed
Segmental fracture
Double
Study of choice to diagnose an occult hip fracture
MRI
Intra-articular fracture
Fracture line enters a joint cavity
Salter-Harris Classification of fractures
Growth (epiphyseal) plate fractures Same Above Lower Through Rammed
Buckle fractures (torus)
When one side of the cortex buckles as a result of compression injury (FOOSH)
Treatment for buckle fracture
4-6 weeks in cast
Greenstick fractures
Occurs in long bones when bowing causes a break in one side of the cortex
Most common sites of dislocation
Anterior shoulder
Posterior elbow
Posterior hip
Treatment for dislocations
Closed reduction, immobilization for 24 weeks
If associated fractures, needs ORIF
Worrisome r/o injury with anterior glenohumeral shoulder dislocation
Axillary nerve injury - pinprick sensation over deltoid
Posterior glenohumeral shoulder dislocations are most commonly associated with:
Seizures, electric shock, trauma
Worrisome r/o injury with humeral shaft gracture
Radial nerve injury
May cause wrist drop
Most commonly fractured bone in children, adolescents and newborns during birth
Clavicle fracture
Complications of clavicle fractures
Pneumothorax, coracoclavicular ligament disruption, hemothorax, brachial plexus injuries
Complications of supracondylar humerus fracture
Median nerve and brachial artery injury - volkmann ischemic contracture (claw-like deformity) from ischemia
+ fat pad sign
Posterior fat pad or displaced anterior fat pad
Radial head fracture
Complications of olecranon fractures
Ulnar nerve dysfunction
Monteggia fracture
Proximal ulnar shaft fracture with anterior radial head dislocation
Management of monteggia fracture
Unstable - ORIF
Galeazzi fracture
Mid-distal radial shaft fracture with dislocation of distal radioulnar joint
Management of Galeazzi fracture
Unstable - ORIF
Sugar tong splint temporarily
Caused from lifting/swinging/pulling a child while forearm is pronated and extended - radial head wedges into the stretched annular ligament
Radial head subluxation (nursemaid’s elbow)
Management of radial head subluxation (nursemaid’s elbow)
Reduction - pressure on radial head with supination and flexion
Management of elbow dislocation
Urgent reduction!
Posterior splint at 90 degrees x 7-10 days
Colle’s Fracture
Distal radius fracture with dorsal/posterior angulation
60% with colle’s fracture also have __________ fracture
Ulnar styloid
Need a ______________ to diagnose colle’s from smiths fracture
Lateral view xr
Smith fracture
Reverse colle’s fracture
Ventral/anterior angulation
Boxer’s fracture
Fracture at neck of 5th metacarpal
Management of boxer’s fracture
Ulnar gutter splint
Management of bite wounds
Augmentin
Diagnosis of patellar frx
