Answer 11

5 cm below trochantic line

Question 12

Answer 12

Open reduction and Internal fixation → interlocking nails, , and plates and screw

Question 13

Complication of fracture subtrochantric?

Answer 13

Nonunion

Question 14

What muscles cause the displacement in midshaft femur?

Answer 14

Proximals by quadriceps and Distal by hamstring muscle

Question 15

Treatments of midshaft fracture

Answer 15

Neonate → pressure bandage no tongue depressor
Childs → closed reduction + skin traction gallows splint and Tomas splint
closed reduction t’ internal fixation by IM wires
closed reduction + external fixation by hip spica
open reduction t’ internal fixation of plate screws

Adults → closed reduction t’internal fixation by ionails → allows early weight bearing
→ open reduction t’internal fixations → plates and screws
