Chapter 21: Orthopedic Surgery; Short
Answer: Arm Surgery; Hip Surgery
Describe colles' fracture. - Answer-A fracture of the distal radius that occurs at the epiphysis within 254
cm of the wrist joint, forcing the hand into a dorsal and lateral position.
What is the most common method of reduction for a colles' fracture?What are the components of the
device? - Answer-An external fixation device. A frame is placed over the pins and the clamps are
secured. Tightening the clamps holds the fracture in reduction.
Put the following steps of an open reduction internal fixation using plates and screws in order. (1-11) -
Answer-1) Pass elevator so surgeon can elevate the periosteum using elevator of surgeon's choice, such
as Key, Hibbs, Hoke, Langenbeck, etc.
2) Reduce fracture using self-retaining bone clamps such as a Lane, Kern, Lewin, or Lowman.
3) Plate is selected and bent prn to fit the angles of the bone using plate benders.
4) Pass plate, usually five or six holes, and bone- or plate-holding forceps to secure plate in place.
5) Pass drill with drill bit and drill guide for the first hole (after completing pretest-runs true with
appropriate speed.)
6) Pass depth gauge to measure the length of the drill hole-surgeon will state the length, which should
be recorded so the appropriate screw is selected.
