Question 51
A 22-year-old right hand-dominant man who fell off his motorcycle onto the tip of his right shoulder 2 weeks ago now reports pain and difficulty raising his right arm. Examination reveals tenderness and gross movement over the lateral scapular spine and severe weakness during resisted abduction. A radiograph and 3D-CT scan are shown in Figures 24a and 24b. What is the next most appropriate step in management?
Explanation
24b The patient has a displaced scapular spine fracture that has resulted in shoulder weakness from a poor deltoid lever arm. The downward tilt may lead to subacromial impingement and rotator cuff dysfunction. Open reduction and internal fixation would best allow normal deltoid and shoulder function. Bone stimulators and abduction bracing may lead to healing but in a malunited position. Arthroscopic acromioplasty and fragment excision should be avoided.

Question 52
A 20-year-old minor league baseball pitcher is diagnosed with a symptomatic torn ulnar collateral ligament (UCL) in his pitching elbow. Nonsurgical management consisting of rest and physical therapy aimed at elbow strengthening has failed to provide relief. He has concomitant cubital tunnel symptoms that worsen while throwing. What is his best surgical option?
Explanation
High-level pitchers with symptomatic UCL tears require reconstruction, with autograft being the best studied graft selection. With concomitant ulnar nerve symptoms, a simultaneous ulnar nerve transposition provides good results. Ligament "repairs" and allograft reconstructions have not shown good long-term results.

Question 53
A 30-year-old man has pain in the left arm after a motor vehicle accident. His neurovascular examination is intact, and radiographs are shown in Figures 25a and 25b. What is the best course of management?
Explanation
25b The floating elbow is best managed with early open reduction and internal fixation of the humeral and forearm fractures, followed by early range of motion. These fractures predispose the elbow to stiffness, and early range of motion is recommended. Solomon HB, Zadnik M, Eglseder WA: A review of outcomes in 18 patients with floating elbow. J Orthop Trauma 2003;17:563-570.

- Yokoyama K, Itoman M, Kobayashi A, et al: Functional outcomes of "floating elbow" injuries in adult patients. J Orthop Trauma 1998;12:284-290.
Question 54
A patient who underwent open reduction and internal fixation of an olecranon fracture 2 months ago now reports painless limitation of motion. Examination reveals a well-healed incision and a flexion-extension arc from 40 degrees to 80 degrees. The patient has been performing home exercises. Radiographs are shown in Figures 26a and 26b. What is the most appropriate treatment?
Explanation
26b The radiographs do not show an articular malunion. Treatment is directed at the soft-tissue contracture and should begin with formal physical therapy and static progressive splinting. Radiation therapy is effective in the perioperative period and is indicated when ectopic bone formation is a concern. Morrey BF: The posttraumatic stiff elbow. Clin Orthop Relat Res 2005;431:26-35.

- King GJ, Faber KJ: Posttraumatic elbow stiffness. Orthop Clin North Am 2000;31:129-143.
Question 55
A 23-year-old professional baseball pitcher reports shoulder pain and decreased velocity while pitching. Physical examination reveals a side-to-side internal rotation deficit of 25 degrees. The O'Brien sign is negative; Neer and Hawkins signs are negative. Rotator cuff strength is full. Radiographs are unremarkable. What is the next step in management?
Explanation
Throwing athletes with symptomatic internal rotation deficits often benefit from an intensive posterior capsular stretching program. Patients that fail to respond to nonsurgical management may benefit from an arthroscopic posterior capsular release. Wilk KE, Meister K, Andrews JR: Current concepts in rehabilitation of the overhead throwing athlete. Am J Sports Med 2002;30:136-151.

Question 56
A 72-year-old woman who is right hand-dominant has severe pain in the right shoulder that has failed to respond to nonsurgical management. She reports night pain and significant disability. Examination reveals 30 degrees of active forward elevation. An AP radiograph is shown in Figure 27. Which of the following treatment options will provide the best functional improvement?
Explanation
The patient has end-stage rotator cuff tear arthropathy. The radiograph shows complete proximal humeral migration (acromiohumeral interval of 0 mm), severe glenohumeral arthritis, and acetabularization of the acromion. In addition, she has "pseudoparalysis" with active elevation of only 30 degrees. Reverse shoulder arthroplasty affords her the best opportunity for pain relief and functional improvement. The other procedures have mixed results but typically are better for pain relief than they are for functional gains.

Question 57
A healthy 64-year-old man just underwent an uncomplicated shoulder arthroplasty for severe glenohumeral osteoarthritis. Intraoperatively, 60 degrees of external rotation was obtained. Postoperatively, he starts on a range-of-motion program. What limitations are recommended?
Explanation
The patient needs restrictions on his external rotation to allow healing of the subscapularis tendon repair. Limitation to 60 degrees is common if the tendon repair is robust and shows no evidence of tension on range-of-motion testing during the surgery. Restriction from external rotation stretching for even 3 weeks would compromise his ultimate functional recovery.

Question 58
A 64-year-old man who was involved in a high-speed motor vehicle accident 6 weeks ago has been in the ICU with a closed head injury. Examination reveals that his range of motion for external rotation to the side is -30 degrees. Radiographs are shown in Figures 28a and 28b. What is the most likely diagnosis?
Explanation
28b The patient has a posterior shoulder dislocation. The AP radiograph shows overlapping of the humeral head on the glenoid. The scapular Y view shows his humeral articular surface posterior to the glenoid. The posterior shoulder dislocation is frequently missed because the patient is comfortable in the "sling" position with the arm adducted and internally rotated across the abdomen. The marked restriction in external rotation on examination raises the suspicion of a posterior dislocation, adhesive capsulitis, or glenohumeral osteoarthritis. The posterior dislocation is diagnosed based on the radiographic findings. An axillary view or CT is recommended to better evaluate the dislocation.

Question 59
A 17-year-old high school football player reports wrist pain 5 months after the conclusion of the football season. A radiograph and MRI scan are shown in Figures 29a and 29b. What is the recommended intervention?
Explanation
29b The patient has a nonunion of the proximal pole of the scaphoid. Acutely, this can be repaired with a screw alone, but as a nonunion the proximal pole has very poor healing potential. Vacularized bone grafts have been successful for these challenging nonunions, particularly in adolescents. A cast can be used for nondisplaced acute waist fractures, and corticocancellous grafts can be used for nonunions of the waist.

Question 60
A 58-year-old woman with a history of severe asthma and long-term prednisone use reports a progression of chronic shoulder pain for the past 6 months. Radiographs and MRI scans are shown in Figures 30a through 30d. What is the most likely diagnosis?
Explanation
30b 30c 30d The patient has osteonecrosis of the humeral head. The radiographs show increased density in the superior subchondral region of the humeral head. The MRI scans reveal a central collapse of the humeral head. The patient's history of severe asthma and long-term prednisone use predisposes her to this condition. The MRI scans show no evidence of a full- or partial-thickness rotator cuff tear. Without a history of fevers, chills, or other systemic signs or symptoms, there is no indication of septic arthritis. The radiographs do not reveal periarticular erosions, commonly seen in rheumatoid arthritis.

Question 61
A 28-year-old man sustained a shoulder dislocation 2 years ago. It remained dislocated for 3 weeks and required an open reduction. He now reports constant pain and has only 60 degrees of forward elevation and 10 degrees of external rotation. He desires to return to some sporting activities. An AP radiograph and intraoperative photograph (a view of the humeral head through a deltopectoral approach) are shown in Figures 31a and 31b. What is the best treatment option to decrease pain and improve function?
Explanation
31b The radiograph and intraoperative photograph show osteonecrosis with near complete head loss/collapse. A stemmed implant is more appropriate in this patient because there is very little bone to support a resurfacing implant. In a younger patient, a glenoid implant should be delayed as long as possible because of the eventual need for revision secondary to glenoid loosening and wear, especially in a young active male. The hemiarthroplasty may be converted to a total shoulder arthroplasty in the future.

Question 62
A 34-year-old man underwent open reduction and internal fixation of a closed both bones forearm fracture 11 months ago. The radiographs shown in Figures 32a and 32b reveal a 3-mm gap and loose screws. What is the best treatment option?
Explanation
32b In an atrophic nonunion with a good soft-tissue envelope, adequate plating with cancellous bone graft can be used to span defects of up to 6 cm. Cortical graft from the fibula or iliac crest is not necessary. BMP-7 is a bone graft substitute and should not be used alone in this patient because the hardware is loose.

Question 63
A football lineman who sustained a traumatic injury while blocking during a game now reports that his shoulder is slipping while pass blocking. Examination reveals no apprehension in abduction and external rotation; however, he reports pain with posterior translation of the shoulder. He has full strength in external rotation, internal rotation, and supraspinatus testing. What is the pathology most likely responsible for his symptoms?
Explanation
Traumatic posterior instability is a common finding in football players, especially in the blocking positions as well as in the defensive linemen and linebackers. A traumatic blow to the outstretched arm results in posterior glenohumeral forces. Labral detachment at the glenoid rim is common. Patients report slipping or pain with posteriorly directed pressure. Rarely do these patients have true dislocations that require reduction; however, recurrent episodes of subluxation or pain are not uncommon. Posterior repair has been shown to be successful in the treatment of traumatic instability. Bottoni CR, Franks BR, Moore JH, et al: Operative stabilization of posterior shoulder instability. Am J Sports Med 2005;33:996-1002. Williams RJ III, Strickland S, Cohen M, et al: Arthroscopic repair for traumatic posterior shoulder instability. Am J Sports Med 2003;31:203-209.

Question 64
A 17-year-old girl has multidirectional instability of the shoulder. What is the most appropriate initial management?
Explanation
Multidirectional instability of the shoulder is defined as symptomatic instability in two or more directions (anterior, posterior) but must include a component of inferior instability. Initial treatment should always include physical therapy and instruction in a home exercise program that emphasizes periscapular and rotator cuff strengthening to improve the dynamic stability of the glenohumeral joint. Immobilization has not been shown to be effective. Open capsular shift and arthroscopic capsular plication remain the surgical options when appropriate nonsurgical management fails (typically a minimum of 6 months of dedicated therapy and home program). Thermal capsulorrhaphy remains controversial but is not recommended by many clinicians because of reported complications including recurrent instability, axillary nerve injury, chondrolysis, and capsular injury.

Question 65
In surgically treating hand and finger infections in patients with diabetes mellitus, what factor is associated with higher amputation rates?
Explanation
Patients with diabetes mellitus are prone to infection, and surgical treatment of their infections frequently requires multiple procedures. The triad of poor wound healing, chronic neuropathy, and vascular disease contributes to the increased infection rate. Studies have demonstrated increased amputation rates in patients with diabetes mellitus who have renal failure or deep polymicrobial or gram-negative infections.

Question 66
A 40-year-old unrestrained passenger reports chest wall pain after a motor vehicle accident. Which of the following structures is most important in preventing the injury shown in Figure 33?
Explanation
Through cadaveric study, Spencer and associates measured anterior and posterior translation of the sternoclavicular joint. The study demonstrated that the posterior sternoclavicular joint capsule is the most important structure for preventing both anterior and posterior translation of the sternoclavicular joint. Gilot GJ, Wirth MA, Rockwood CA: Injuries to the sternoclavicular joint, in Bucholz RW, Heckman JD, Court-Brown C (eds): Fractures in Adults.

Question 67
Figures 34a and 34b show the axial and sagittal MRI scans of a 36-year-old man who reports the insidious onset of pain in the right shoulder. What is the most appropriate description of the acromial morphology?
Explanation
34b The MRI scans reveal a meso os acromiale with edema at the site in a skeletally mature patient.

Question 68
What is the primary indication for performing a total wrist arthroplasty in a patient with painful rheumatoid arthritis?
Explanation
The most conservative indications for a total wrist arthroplasty are to spare motion on one side and to improve activities of daily living. Component loosening, dislocation, and wound problems are frequent. Suitable patients can be of various ages, wrist motion, and radiographic stages of arthritis. Ipsilateral total elbow arthroplasty, type III degenerative changes of the wrist, age older than 55, and limited range of motion are neither primary indications nor contraindications to a total wrist arthroplasty.

Question 69
What is the most likely cause of the lesion shown in Figures 35a and 35b?
Explanation
35b The most common cause of myositis ossificans is contusion. Certain regions, including the quadriceps and brachialis, are more commonly affected. The mechanisms of development have not been clearly established. Beiner JM, Jokl P: Muscle contusion injuries: Current treatment options. J Am Acad Orthop Surg 2001;9:227-237.

Question 70
During treatment of rupture of the subscapularis tendon with associated biceps instability, treatment of the biceps tendon should include which of the following?
Explanation
With subscapularis tendon ruptures that have biceps tendon pathology, treatment with tenodesis or tenotomy has improved clinical results. Subluxation or dislocation of the biceps tendon is common with subscapularis rupture. Dislocation of the biceps can occur either beneath the tendon, within the tendon, or extra-articularly. In all cases, the restraints to medial translations of the biceps have been disrupted. Attempts at recentering the biceps have not been successful, and clinical results appear to be improved when tenodesis or tenotomy is employed in the treatment of the unstable biceps associated with subscapularis tears.

Question 71
What is the most common bacteria cultured from dog and cat bites to the upper extremity?
Explanation
To define bacteria responsible for dog and cat bite infections, a prospective study yielded a median of five bacterial isolates per culture. Pasteurella is most common from both dog bites (50%) and cat bites (75%). Pasteurella canis was the most frequent pathogen of dog bites, and Pasteurella multocida was the most common isolate of cat bites. Other common aerobes included streptococci, staphylococci, moraxella, and neisseria.

Question 72
A previously healthy 65-year-old woman has a closed fracture of the right clavicle after falling down the basement stairs. Examination reveals good capillary refill in the digits of her right hand. Radial and ulnar pulses are 1+ at the right wrist compared with 2+ on the opposite side. In the arteriogram shown in Figure 36, the arrow is pointing at which of the following arteries?
Explanation
The axillary artery commences at the first rib as a direct continuation of the subclavian artery and becomes the brachial artery at the lower border of the teres major. The arteriogram reveals a nonfilling defect in the third portion of the artery just distal to the subscapular artery. The complex arterial collateral circulation in this region often permits distal perfusion of the extremity despite injury.

Question 73
Which of the following structures may help maintain radial length after a radial head fracture?
Explanation
Essex-Lopresti injuries affect axial stability of the forearm. Injury to the interosseous membrane or the triangular fibrocartilage complex can result in proximal migration of the radius.

Question 74
An adult patient has a closed humeral fracture that was treated nonsurgically and a concomitant radial nerve injury. Six weeks after injury, electromyography shows no evidence of recovery. Management should now consist of
Explanation
In patients with radial nerve injuries with closed humeral fractures, it has been reported that 85% to 95% spontaneously recover. Based on this premise, most surgeons favor expectant management of these injuries. Even if there is no evidence of recovery at 6 weeks, repeat electromyography at 12 weeks is advocated. If there is no clinical or electromyographic signs of recovery at 6 months, exploration is recommended. If the nerve is in continuity at the time of exploration, nerve action potentials are useful in helping determine the need for neurolysis, excision, and grafting, or if excision and repair is the best option.

Question 75
A 55-year-old man who works as a carpenter reports chronic right anterior shoulder pain and weakness. Examination reveals 90 degrees of external rotation (with the arm at the side) compared to 45 degrees on the left side. His lift-off examination is positive, along with a positive belly press finding. An MRI scan reveals a chronic, retracted atrophied subscapularis tendon. What is the most appropriate management of his shoulder pain and weakness?
Explanation
Chronic subscapularis tendon ruptures preclude primary repair. In such instances, subcoracoid pectoralis major tendon transfers may improve function and diminish pain. The subcoracoid position of the transfer allows redirection of the pectoralis major in a direction recreating the vector of the subscapularis tendon. Shoulder fusion is a salvage procedure, and corticosteroid injection may reduce pain but will not improve function.
