What is 155 degrees?
The most helpful physical examination finding to diagnose a fixed posterior shoulder dislocation
What is lack of external rotation?
Numbness in the lateral forearm with weakness in elbow flexion are the physical findings that correspond to an injury of this nerve during open coracoid transfer for treatment of recurrent anterior shoulder instability.
What is the musculocutaneous nerve?
The moving valgus stress test is designed to test this structure of the elbow
What is the anterior band of the ulnar collateral ligament?
This bundle of the medial collateral ligament complex is tight from 30-90 degrees of elbow flexion
What is the anterior bundle?
Recommended treatment for this 43-year-old male with severe shoulder pain 2 years s/p hemiarthroplasty with biological resurfacing of the glenoid and normal elevation and external rotation strength


What is revision to TSA?
Recommended treatment for this injury in an obese 58-year-old female


What is radial head replacement?
The most likely reason for shoulder weakness in a patient who sustained a traumatic glenohumeral dislocation who has intact sensation and the inability to actively elevate his shoulder
What is massive rotator cuff tear?
A tear of the structure circled in the ultrasound below results in definitive loss of this function

What is forearm supination endurance?
Kocher approach to the elbow involves this muscular interval
What is anconeus and extensor carpi ulnaris?
Recommended treatment for this 71-year-old male s/p uncomplicated TSA 1 year ago with sudden onset severe pain and normal laboratory studies


What is revision total shoulder replacement?
The most common risk factor for failure of arthroscopic labral repair performed after traumatic anterior dislocation with a history of prior arthroscopic labral repair


What is the presence of a preoperative glenoid defect?
Equal amounts of fat and muscle within the rotator cuff seen on shoulder MRI scan is consistent with this Goutallier stage of fatty infiltration
What is stage 3?
Recommended treatment for this fracture in a 79-year-old female rheumatoid patient

What is total elbow replacement?
This arm position should be avoided during the early rehabilitation of a lateral collateral ligament reconstruction of the elbow
What is varus positioning?
An objective improvement in external rotation can be achieved with repair of this structure during a reverse total shoulder replacement for treatment of acute 4-part proximal humerus fracture
What is the greater tuberosity?
A patient with a painful shoulder and this MRI scan will likely have weakness in this position

What is weakness with external rotation in 90 degrees of abduction?
The most common preoperative risk factor for the development this postoperative complication

What is history of prior surgery?
Recommended treatment for this 42-year-old man with isolated traumatic brain injury who presents with elbow pain, limited motion, altered sensation in his small and ring fingers and limited grip strength

What is excision of heterotopic ossification and ulnar nerve transposition?
Structure injured during placement of the accessory anterolateral portal during elbow arthroscopy resulting in weakness in finger extension and ulnar deviation of the wrist with wrist extension
What is the posterior interosseous nerve?
Stated relative to the coronal and sagittal planes, the offset of the native humeral head center of rotation lies in this direction relative to the center of the humeral intramedullary canal
What is 8 mm posterior and 4 mm medial?
Active range of motion exercises of the elbow should be initiated at this time point after treatment of the below injury to ensure good outcomes

What is 48 hours?
Lateralization of the center of rotation in a reverse total shoulder replacement will alter the baseplate-bone interface forces in this manner
What is increase baseplate-bone interface forces?
The most common factor associated with the presence of postoperative ulnar neuropathy following treatment of an intra-articular distal humerus fracture
What is ulnar nerve transposition?
Elbow positioning sequence of events to perform the lateral pivot-shift test of the elbow
What is elbow extension followed by elbow flexion with valgus and supination moments along with axial compression?
