Which of the following methods accurately describes the measurement of tip-apex-distance as it relates to placement of a lag screw in the femoral head?
Summation of the distance between the end of the screw and the apex of the femoral head on AP and lateral radiographs
Distance from the acetabular teardrop to the tip of the screw on an AP radiograph of the hip
Multiplication of the distance between the end of the screw and the apex of the femoral head on AP and lateral radiographs
Distance from the center of the lesser trochanter to the tip of the screw on an AP hip radiograph
Summation of the distance between the tip of the greater trochanter and end of the screw on AP and lateral hip radiographs
A 72-year-old male sustains the injury shown in Figure A as a result of a fall from a ladder. Which of the following factors has been shown to be associated with increased collapse or sliding displacement?
Use of a long intramedullary device
Use of a short intramedullary device
Use of external fixation
Postoperative weight bearing status
Intraoperative fracture of the lateral femoral wall
When treating a stable 2-part intertrochanteric hip fracture with a sliding hip screw construct, what is the minimum number of screw holes that are needed in the side plate for successful fixation?
Which of the following statements is true regarding treatment of intertrochanteric hip fractures with an intramedullary nail versus a sliding hip screw?
