A 72-year-old male presents 2 years status post fixation of an impending pathologic right femur fracture due to metastatic renal cell carcinoma. He is minimally ambulatory due to pain. Despite radiation therapy, there has been progression of the lesion with extensive cortical bone loss, which is shown in Figure A. A proximal femoral replacement arthroplasty is performed without complications, and is demonstrated in Figure B. Which of the following is true regarding this patients post-operative course?

1. Deep prosthetic infection is the most common complication

2. Mean Harris Hip score will likely not improve

3. The patient will most likely continue to be minimally ambulatory

4. Aseptic failure rate at 5 years is >50%

5. Pre-operative radiation decreases the risk of infection post-operatively

Non operative management of hip arthritis:

Activity modification:
Reduction of impact-loading exercises
Reduction of weight
Avoidance of stairs, inclines, squatting
Physical therapy

Nonnarcotic medications:
NSAIDs
Evidence does not support the use of glucosamine sulfate.

Joint injections:
Corticosteroid—antiinflammatory treatment
Hyaluronate
Backbone of proteoglycan chain of articular cartilage
No strong evidence to support use in the hip
Not approved by FDA for hip use in United States

Assist device (cane or crutch)
Opposite hand of affected hip

A 10-year-old boy with a spiral midshaft femur fracture from a sledding injury presents to the emergency department for evaluation. He is 48 inches tall and weighs 120 pounds. The BEST option for treatment would be:

a. Long-leg cast
b. Traction then long-leg cast
d. Retrograde flexible intramedullary nails
e. Rigid, straight antegrade intramedullary nail
f. Submuscular plating

An 8-year-old boy presents to the emergency department with a Salter-Harris type IV fracture of the distal femur from a football tackle. The fracture has 3 mm of displacement and 15 degrees of angulation in the sagittal plane. Because of his young age you know he has excellent potential to remodel. The BEST treatment option would include:

a. Long-leg cast
b. Percutaneous pinning in situ
c. Open reduction and internal fixation with distal femoral locking plate
d. Open reduction and internal fixation of the metaphyseal component but not the epiphyseal component to avoid potential growth arrest
e. Open reduction and internal fixation of both components with plates and/or screw fixation
