tibial fracture. It is most important to evaluate and
document the dorsalis pedis and posterior tibial pulses
as well as the function of the peroneal nerve.


  • The physician must also rule out compartment syn-
    drome in a patient with a fractured tibia. Common
    sensitive predictors of compartment syndrome are
    pain with passive stretch of the musculotendinous unit
    that travels through the respective compartment or
    sensory loss in the distribution of nerves that traverse
    the compartment. Further discussion of compartment
    syndrome can be found in Chapter 56. Table 64-1 out-
    lines the various compartments of the lower leg.

  • The joints above and below all tibia fractures must be
    thoroughly examined. Therefore, a careful clinical
    and radiologic evaluation and assessment of the ipsi-
    lateral knee and ankle is mandatory. The physician
    should evaluate the range of motion and the integrity
    of the ligamentous complex at both joints respec-
    tively. Studies have shown that there is an increased
    incidence of ligamentous injury to the knee with frac-
    tures of the tibial shaft (Templeman and Marder,
    1989).


RADIOGRAPHIC EXAMINATION



  • The physician evaluating a tibial fracture must include
    anterior-posterior and lateral radiographic views of
    the tibia and three-view radiographs of the ipsilateral
    knee and ankle.

  • Computed tomography (CT) may aid in determining
    the precise location, depth, and articular involvement
    of tibial plateau and plafond fractures; however, these
    are not a part of the initial radiological evaluation for
    fractures of the tibial shaft. Magnetic resonance imag-
    ing may be used to investigate stress fractures, but a
    bone scan is the radiographic study of choice (Daffner
    and Pavlov, 1992).

    • When describing fractures of the tibia, the reporting
      physician should include the following: open versus
      closed, proximal versus middle versus distal 1/3, com-
      munition with number of fragments, transverse/spiral/
      oblique, angulation, shortening or overlap, and dis-
      placement.




TIBIAL SHAFT FRACTURES

•Fractures of the tibial shaft are due to varying
amounts of energy. High energy fractures more com-
monly present with a higher likelihood of compart-
ment syndrome, higher likelihood of being open, and
tend to be more comminuted with soft tissue damage.
Tscherne and Gotzen first described and classified the
soft tissue injury associated with these fractures
(Tscherne and Gotzen, 1984) (see Table 64-2).
•Treatment options for tibial shaft fractures vary widely
and depend upon the degree of comminution, displace-
ment of fragments, and location of fracture. Treatment
options range from closed reduction with long leg cast-
ing to open reduction with internal fixation or
intramedullary nailing. External fixation may be appro-
priate in cases of open fracture, high energy trauma, and
soft tissue injury or infection. Studies have suggested
that operative intramedullary nailing is more successful
