cerclage wire before inserting stem(to prevent crack propagation)
ignore the fracture if fully porous coated stem is used (provided there is no distal propagation)
fully porous coated stem, or tapered fluted stem provided
wires/cables/claw plate for isolated GT fractures
cerclage wire (if implant stable)
fully porous coated stem to bypass defect (if implant unstable) ± strut allograft
PWB and observation (if detected postop)
Often requires treatment that addresses the osteolysis.
AG fractures with <2cm displacement, treat nonoperatively with partial WB and allow fibrous union.
AG fractures >2cm needs ORIF (loss of abductor function leads to instability) with trochanteric claw/cables.

A nondisplaced periprosthetic small posterior wall acetabular fracture is noted intra-operatively during total hip arthroplasty.

Which of the following treatment options will best maintain motion and clinical function?
ORIF of the posterior column and THA revision
Cage reconstruction of acetabular component
THA revision using a cemented acetabular component
Placement of a hip abductor brace and non-weight bearing in the affected limb
No change in treatment
During insertion of a cementless femoral stem, a nondisplaced fracture is noticed along the femoral calcar. Which of the following is the most appropriate next step in surgical management?

A 67-year-old man who underwent total hip arthroplasty (THA) 4 years ago fell on to his right hip. His pre-injury right hip film is seen in Figure A while films of his current injury are seen in Figures B and C. Prior to the fall he had no thigh or hip pain. His ESR and CRP are within normal limits. During intraoperative assessment, the acetabular and femoral stems are found to be well fixed. What is the next best course of action?
Revision of the acetabular component and ORIF of the femur with locking plates and cerclage wires
Revison of the femoral component, bypassing the fracture by two cortical diameters
Revision of the femoral component with impaction grafting and cerclage wires
Revision to a cemented component, bypassing the fracture by two cortical diameters
ORIF of the femur with locking plates and cerclage wires
Figure A shows the image of a 72-year-old male who sustained a fall from standing. Past medical history is significant for hypertension. He was a community ambulator without the use of a cane or walker prior to the fall. During the operation, he is noted to have a well-fixed acetabular component without significant wear of his polyethylene liner, but his femoral component is easily extractable. Which of the following correctly pairs his Vancouver classification and appropriate surgical intervention?
Vancouver A, Revision of femoral component to cemented stem with fixation of the fracture
Vancouver B1, Revision of femoral component to cemented stem with fixation of the fracture
Vanvouver B1, Revision of femoral component to a long, porous-coated, cementless stem with fixation of the fracture
Vancouver B2, Fixation of the fracture with a plate and cerclage wires
Vancouver B2, Revision of femoral component to a long, porous-coated, cementless stem with fixation of the fracture
A previously healthy 68-year-old woman falls and sustains the fracture seen in Figure A. Her index procedure was approximately 10 years ago. The patient is taken to surgery, and the femoral stem is found to be loose. The acetabular component is found to be well fixed in good position. In addition to using a new poly liner, what other procedure(s) is now indicated in this patient?
Cemented femoral revision
Retention of current hardware and fixation using cerclage wires
Open reduction and internal fixation with a locking plate
Both uncemented femoral revision and revision of the acetabular shell
Uncemented femoral revision bypassing the distal deficiency by two cortices.
A 67-year-old man 6 years status post right total hip arthroplasty falls while walking his dog. He complains of pain and is unable to bear weight through the right leg. He denies any hip or thigh pain prior to this fall. A radiograph is provided in figure A. Which of the following is the most appropriate management?
Traction for 3 weeks followed by 2 months of non-weight bearing mobilization
Open reduction and plate fixation with cable augmentation proximally
Revision arthroplasty with a cementless long stem bypassing the fracture site by two cortical diameters
Revision arthroplasty with cemented femoral stem bypassing the fracture site by two cortical diameters
Revision arthroplasty with cementless long stem bypassing the fracture site by two cortical diameters and allograft strut augmentation
An 82-year-old male sustains a ground level fall and sustains the injury shown in Figure A. Which of the following treatment methods is most appropriate for treating this injury?
Closed reduction and functional bracing
Open reduction and fixation with a plate with screws and cerclage cables

Revision hip arthroplasty with bridging of the fracture with a plate with screws and cerclage cables
Total femoral replacement
A 78-year-old female undergoes total hip arthroplasty through a minimally invasive surgical approach. During insertion of a metaphyseal fixation stem with a cementless press-fit technique, a crack in the calcar is identified. The stem is removed, two cable wires are passed around the calcar, and the same stem is reinserted. Which of the following statements is true?
The patient should be advised she is at greater risk of stem subsidence and early revision
Female sex is a risk factor for intraoperative calcar fracture
A better outcome would be expected if a long-stem diaphyseal fixation stem had been inserted after recognition of the calcar fracture
Cementless press-fit technique is not a risk factor for intraoperative fracture
Minimally invasive surgical approach is not a risk factor for intraoperative fracture
A 88-year-old female fell onto her right hip sustaining the fracture shown in Figure A. Past medical history is significant for mild dementia and moderate coronary artery disease.

HPI - h/o Bipolar 5 years ago for a femoral neck fracture
sustained a fall 6 months after surgery sustaining a periprosthetic fracture. It was fixed with a locking plate, screws, and cerclage wires.
Has not been able to bear weight for last 4-5 months. No h/o fever or recent trauma.
What is your choice for surgical management of this case?
HPI - 59F with a history of THA revision for loosening, and two subsequent debridements at outside institution complains of L thigh pain and deformity after feeling a snap getting out of bed 3 days ago. Has been non-weight bearing on that side for 1 year per her orthopaedist's recommendations. Started on IV vancomycin 3 weeks ago for "osteomyelitis" of the femur. Lives with husband and daughter. Works as a secretary.
How would you treat the patient at this time (on Vanco for 3 weeks)?
