Closed reduction with cannulated screw fixation
Open reduction with cannulated screw fixation
Closed reduction and short intramedullary nail fixation
A 65-year-old patient sustains the injury shown in Figure A. His medical history is significant for hypertension, Type 2 diabetes and dialysis dependent chronic kidney failure. A postoperative radiograph is shown in Figure B. Based on his risk factors, what is his most likely post operative mortality at two years after surgery?
Which of the following injuries is anticipated to have a 20% chance of mortality and 50% chance of loss of independence at one year when sustained by an 85-year-old female?
Intra-articular distal humerus fracture
Distal radius fracture
Femoral neck fracture
Trimalleolar ankle fracture-dislocation
Periprosthetic distal femur fracture
A 48-year-old active female runner underwent percutaneous screw fixation of a minimally displaced femoral neck fracture six months ago. There were no immediate post-operative complications, and she was progressed to full weight bearing three months after surgical fixation. Initial post-operative radiographs, and radiographs taken 3 months post-op revealed anatomic reduction of the fracture with no shortening. At her latest clinic visit she reports severe right groin pain, and difficulty ambulating. A current radiograph is shown in Figure A. What is the most appropriate surgical treatment?
In situ dynamic hip screw revision fixation
Core decompression and bone grafting
Valgus intertrochanteric osteotomy with blade fixation
Open reduction, bone grafting, and revision percutaneous screw fixation
Which of the following cannulated screw configurations used in the treatment of subcapital femoral neck fractures is optimal?
Inverted triangle pattern with the inferior screw posterior to midline and adjacent to the calcar
Inverted triangle pattern with the inferior screw anterior to midline and adjacent to the calcar
Triangle pattern with the superior screw posterior to midline and adjacent to the calcar
Inverted triangle pattern with the inferior screw posterior to midline and central in the femoral neck
Inverted triangle pattern with the inferior screw anterior to midline and central in the femoral neck
A 15-year-old male falls from his bicycle and lands directly on his left hip. He is unable to bear weight and presents to the emergency department with the AP pelvis radiograph seen in Figure A. Which of the following radiographic views could aid in classifying this patient's fracture pattern?
Iliac oblique (Judet) view
Traction AP of the hip with the leg in neutral rotation
Outlet view of the pelvis
Traction AP of the hip with the leg internally rotated 15°
Traction AP of the hip with the leg externally rotated 15°
A 25-year-old man sustains the fracture seen in Figure A and is seen in pre-op holding prior to surgery. What position of his lower extremity would result in the lowest intracapsular hip pressure?
Neutral rotation and flexion
External rotation and flexion
Internal rotation and extension
External rotation and extension
Internal rotation and flexion
A 79-year-old cyclist is involved in an accident and sustains a displaced femoral neck fracture as seen in Figure A. What is the optimal treatment?
Open reduction internal fixation
Total hip arthoplasty
A 27-year-old man sustains a displaced femoral neck fracture and undergoes urgent open reduction internal fixation. What is the most prevalent complication after this injury?
Poor pre-injury cognitive function has been proven to increase mortality for which of the following injuries?
Proximal humerus fracture
Pelvic ring fracture
Distal femur fracture
A 70-year-old woman trips on the grass while playing golf and sustains a displaced comminuted femoral neck fracture. What is the optimal treatment for this patient?
Total hip arthroplasty
Traction and non operative treatment
A 65-year-old male falls from a standing height and sustains the injury seen in Figure A and undergoes the treatment seen in Figure B. Compared to a total hip arthroplasty, this treatment is associated with which of the following:

A 75-year-old ambulatory male who lives independently presents with the fracture shown in Figure A. Which of the following is true regarding timing of surgical fixation and post-operative mortality?

Delay of surgery due to treatment of acute medical comorbidities has no effect on post-operative mortality rates
90 day mortality rate is decreased if surgery is delayed greater than 7 days
Timing of surgical fixation has no statistically significant affect on post-operative mortality
