Figure A is the radiograph of a 43-year-old right hand dominant male presents to the ED following a ground level fall. On examination he has positive valgus stress, moving valgus stress, and milking maneuver. He has a negative lateral pivot shift. He is placed into a posterior splint with the forearm in full supination. Based on this patient's radiographs and clinical examination, which of the following best describes his primary instability?
Posteromedial rotatory instability with torn LUCL
Posteromedial rotatory instability with intact LUCL
Posterolateral rotatory instability with torn LUCL
Posterolateral rotatory instability with intact LUCL
Terrible triad of the elbow

A 34-year-old male presents with elbow pain after sustaining a ground level fall 2 weeks ago. An injury radiograph is shown in Figure A. Which of the following provocative maneuvers will most likely be positive?
Lateral pivot shift test
Chair rise test
Posterior drawer test
Gravity-assisted varus stress test
When evaluating a fracture dislocation of the elbow, a varus and posteromedial rotation mechanism of injury typically results in what injury pattern?
A fracture of the radial head requiring ORIF
A highly comminuted radial head fracture requiring radial head arthroplasty or resection
An MCL injury requiring repair
A type I avulsion fracture of the coronoid
An anteromedial coronoid fracture
A 25-year-old male sustains a closed elbow dislocation after falling during a soccer game. Two months later, the patient continues to complain of pain and instability. Radiographs and physical exam are concerning for posteromedial instability. Which of the following fracture patterns is most consistent with this diagnosis?
Coronoid anteromedial facet
Capitellar impaction injury
A 35-year-old zookeeper fell 10 feet while preparing an exhibit for a grand reopening, landing on his left arm. The patient is then evaluated by a keen orthopedic resident in the emergency room who describes the zookeeper's injuries to his chief. He describes a comminuted radial head fracture and posterolateral ulnohumeral dislocation. The chief resident orders a CT scan which demonstrates a coronoid fracture involving 50% the height with no involvement of the anteromedial facet. During surgery, the trauma surgeon replaces the radial head and repairs the lateral collateral ligament complex. The elbow is splinted in elbow flexion and pronation. The patient begins range of motion exercises with her occupational therapist 3 days after surgery, and her elbow dislocates. What is the most likely reason for her instability?
Length of immobilization
Position of immobilization
Lack of coronoid fixation with medial buttress plate
Lack of coronoid fixation from lateral approach
Lack of medial collateral ligament repair
