On examination, he has good distal pulses, weakness with attempted wrist extension, and some reported numbness of the dorsal radial hand. He is treated conservatively in a Sarmiento functional brace. Which muscle function is expected to be the LAST to return in this patient?

A 60-year-old male with a history of diabetes presents to the trauma bay after sustaining a ground-level fall onto his right arm. His injury films are shown in Figures A and B. He is treated conservatively with closed reduction and his post-reduction radiographs are shown in Figures C and D. At 6 weeks followup he presents with persistent fracture site motion. His current imaging studies are shown in Figures E and F. Which of the following is the best next step in management?
Adjust Sarmiento brace and repeat followup in 3 weeks
Continue current management for another 6 weeks and then discontinue brace
Proceed with surgical management at this time
Continue current management for another 6 weeks and if no evidence of clinical union, proceed with surgical management
Discontinue sarmiento brace and allow for progressive weight-bearing at this time
A 45-year-old man presents to your clinic with a closed mid-shaft humerus fracture after a fall 1 week prior. He is neurovascularly intact. After a discussion of his treatment options, he is adamant about proceeding with surgical management. With respect to open reduction and internal fixation with a plate versus intramedullary nailing, what advice can you offer him?
Nailing is associated with a decreased rate of surgical site infections
Nailing is associated with a higher rate of transient radial nerve injury
Plating is associated with a higher rate of fracture union
Plating is associated with a higher re-operation rate
No difference between rate of radial nerve palsy between plating or nailing this injury
A 65-year-old man sustained the closed injury seen in Figures A and B and is being treated nonoperatively in a functional brace. At what time point after the injury does the lack of callus formation and motion at the fracture site first become concerning for nonunion?

Using the 'damage-control' approach to orthopaedic trauma, what would be the best initial management for the injury seen in Figure A?
Closed reduction and splinting in the emergency room
Irrigation and debridement, then splinting in the operating room
Irrigation and debridement, then spanning external fixation in the emergency room
Open reduction and internal fixation with a compression plate in the operating room
Irrigation and debridement, then intramedullary nailing of the humerus in the operating room

Continue current splint for 6 weeks
Continue current splint for 3 weeks and transition to hanging arm sling for additional 3 weeks
Transition to functional brace for additional 6-8 weeks
Open reduction internal fixation with compression plating
Staged procedure with humeral external fixator, then open reduction internal fixation with compression plating

A 23-year-old man presents with the injury seen in Figure A after a motor vehicle collision. He undergoes the treatment seen in Figure B. Which of the following statements is most accurate when comparing his treatment with open reduction and internal fixation?
Higher rates of radial nerve injury
Higher total complication rate
Lower rates of nonunion
Lower rates of shoulder impingement
Lower rates of malunion
A 42-year-old man sustains the injury shown in Figure A after a fall from 6 feet. Physical exam after the injury reveals a flaccid ipsilateral limb. An MRI is performed that reveals nerve root avulsions from C5-T1. Which of the following is the most appropriate management of his fracture at this time?
Closed management with a coaptation splint
Closed management with a coaptation splint followed by transition to a functional brace after 7-10 days
External fixation of humeral shaft fracture until brachial plexus injury resolves
Open reduction, surgical fixation with plating
Closed management with a sling until brachial plexus injury resolves
A 26-year-old right hand dominant male is involved in a motor vehicle collision and sustains the left humerus injury demonstrated in Figure A. The brachial artery is disrupted and requires urgent attention in the operating room. The patient's preoperative nerve evaluation demonstrates that the patient is unable to initiate extensor carpi radialis longus, extensor carpi radialis brevis, extensor pollicis brevis, extensor digitorum, extensor indicis proprius, and extensor pollicis longus motor activity. What is the most likely etiology for this observed neurologic examination?
Neurapraxia of the median nerve
Axonotmesis of the radial nerve
Neurotmesis of the ulnar nerve
Neurotmesis of the radial nerve
Axonotmesis of the ulnar nerve
A 45-year-old male sustains a Gustilo and Anderson Type II open transverse humeral shaft fracture. He undergoes the treatment shown in Figures A and B. What is the advantage of this treatment choice as compared to antegrade intramedullary nailing?
