Prefabricated functional braces for the treatment of fractures of the tibial diaphysis
A Sarmiento, PA Sobol, AL Sew Hoy, SD Ross, WL Racette and RR Tarr
We have reviewed our experiences with prefabricated functional braces in
the treatment of diaphyseal tibial fractures. The braces were developed in
an attempt to reduce the occasional technical difficulties encountered with
the use of custom-made braces. Between January 1979 and July 1983 we
treated 625 diaphyseal tibial fractures. One hundred and eighty-six
patients (29.8 per cent) were lost to follow-up, the braces had to be
discontinued in thirty-eight (9.2 per cent), and ten fractures (2.5 per
cent) failed to unite. We conducted careful radiographic and clinical
analyses of the remaining 391 patients. Two hundred and fifty-seven (65.7
per cent) of the fractures were closed and 134 (34.3 per cent) were open.
Three hundred and fifty-seven (91.2 per cent) of the patients had ten
millimeters of final shortening or less, and 306 (78.3 per cent) had a
final angulation of 5 degrees or less. The average time from injury to
bracing was 3.9 weeks (range, one to twelve weeks) for the closed fractures
and 5.0 weeks (range, one to twelve weeks) for the open fractures. These
findings appear to support our concept that function of the extremity is
beneficial to osteogenesis and that many diaphyseal tibial fractures can be
satisfactorily stabilized in prefabricated functional braces. These braces
also have the advantage of not immobilizing the adjacent joints and they
permit the gradual restoration of weight-bearing.
