A 70-year-old right-hand dominant female presents to your office complaining of continued right shoulder pain 12 weeks after falling from a ladder, despite participating in a rigorous physical therapy program. She was initially reduced in the emergency department and her injury films are shown in Figures 1 and 2.

MRI brachial plexus; axillary nerve palsy
MRI cervical spine; C5 and C6 nerve root radiculopathy
MRI right shoulder; rotator cuff tear

A 27-year-old male reports right shoulder pain after sustaining a fall at work 3 weeks ago. He is found to have a rotator cuff injury with medial subluxation of the long head of the biceps tendon. Which of the nerves labeled in Figure A innervates the rotator cuff muscle that is likely injured in this patient?
A 47-year-old landscaper presents with worsening left shoulder pain and weakness. Three years ago, he injured the left shoulder in a fall and elected for nonoperative management to minimize time off from work. Physical therapy was effective until 6 months ago when his shoulder function worsened to the point that he is now unable to work. Examination of his active range of motion reveals forward elevation 120° with pain, abduction 100°, IR at neutral to T8 and ER at neutral 5°. He has a positive ER lag sign and Hornblower's sign. Belly press and lift-off tests are normal. A recent radiograph is shown in Figures A. MRI images are shown in Figures B and C. Which of the following is the best treatment option?
Continue physical therapy
