A 62-year-old man complains of shoulder pain for 2 years. He has had 1 course of intra-articular sodium hyaluronate and 6 weeks of physical therapy with little relief. Examination reveals diminished arm flexion and abduction secondary to pain. Radiographs of his shoulder are shown in Figures A and B. According to the American Academy of Orthopaedic Surgeons Clinical Practice Guidelines, what is the next best step?
Humeral head replacement arthroplasty
Hemiarthroplasty and ream-and-run glenoid procedure
Cuff tear arthropathy (CTA) prosthesis
Total shoulder arthroplasty with a metal-backed cemented glenoid component
Total shoulder arthroplasty with an all-polyethylene cemented glenoid component

A 47-year-old male with a history of a Putti-Platt procedure 20 years ago presents with right shoulder pain with decreased range-of-motion. Radiograph is shown in Figure A. What is the most accurate diagnosis?
Arthritis from poor placement of coracoid transfer
Which of the following factors has the greatest influence on early postoperative restrictions following total shoulder arthroplasty through a deltopectoral approach?
Release of the superior border of the pectoralis
Strength of the capsular repair
Strength of the subscapularis repair
Presence of glenoid retroversion
Quality of the patients' bone
During the initial rehabilitation phase following total shoulder arthroplasty through a delto-pectoral approach, motion and strengthening are typically restricted because of which factor?
Protection of the subscapularis tendon
Protect of the supraspinatus tendon
Risk of dislocation
Risk of loosening
Which of the following preoperative factors is a contraindication to total shoulder arthroplasty?
Passive external rotation less than 10 degrees
Eccentric posterior glenoid erosion
A 2-cm full-thickness supraspinatus tendon tear
A preganglionic brachial plexus injury
A 65 year-old man has progressive debilitating pain and crepitus in his shoulder. Active forward elevation is 120 degrees and external rotation strength is normal. Radiograph and CT scan are shown in Figures A and B. Which treatment will likely give him the best outcome in 3 years.
Arthroscopic capsular release
Humeral head arthroplasty with glenoid bone grafting followed by staged glenoid component implantation
Reverse total shoulder replacement
Total shoulder arthroplasty
In which of the following clinical circumstances would it be appropriate to eccentrically ream the anterior glenoid?
72-year-old male undergoing a shoulder arthroplasty due to rotator cuff arthropathy
65-year-old female with a glenoid retroversion of 13-degrees undergoing shoulder arthroplasty
70-year-old female with humeral anteversion of 13-degrees undergoing shoulder arthroplasty
65-year-old female with glenoid retroversion of 25-degrees undergoing shoulder arthroplasty
59-year-old male with significant glenoid bone stock deficiency and severe osteoarthritis
A 62-year-old man undergoes a total shoulder arthroplasty for osteoarthritis. He accidently uses his operative arm to rise from a chair 3 weeks after surgery and thereafter complains of anterior shoulder pain. Radiographs are significant for anterior dislocation of the prosthesis. What is the most likely mechanism for this complication?
long head biceps rupture
Which of the following statements regarding propionibacterium acnes infections after shoulder arthroplasty is incorrect?
It is usually associated with fevers
Cultures need to be held for 14 days
It colonizes the shoulder at increased rates compared to the knee and hip
Men have a higher bacterial burden than females
It is an important cause of clinical implant failure
During a total shoulder arthoplasty (TSA), which of the following technical maneuvers would most likely place the rotator cuff tendons at risk of injury?
Excessive retraction on the deltoid muscle during a delto-pectoral approach
Palpation of the rotator cuff insertion prior to humeral head resection
A humeral cut with 30 degrees of retroversion
Excessive bone removal with the humeral neck osteotomy
A humeral cut with 45 degrees of inclination
A 72-year-old male who underwent right total shoulder arthroplasty 8 months ago is unable to lift his right hand off his back and has weakness with internal rotation. What is the most likely diagnosis?
Long head of biceps rupture
Subscapularis nerve palsy
Standard postoperative recovery
A 75-year-old right-hand dominant female has persistent right shoulder pain for the past 5 years. An axial CT scan is shown in the Figure A. If a total shoulder arthroplasty is planned, what other procedure must be performed based on this patient's imaging?
rule out infection
bone grafting of the glenoid
rotator cuff repair
humeral head biopsy
The placement of a standard all-polyethylene glenoid component for shoulder arthroplasty is contraindicated in which of the following scenarios?
Irreparable rotator cuff tear
Previous glenoid resurfacing
