Jf. Keating et al., LOCKING INTRAMEDULLARY NAILING WITH AND WITHOUT REAMING FOR OPEN FRACTURES OF THE TIBIAL SHAFT - A PROSPECTIVE, RANDOMIZED STUDY, Journal of bone and joint surgery. American volume, 79A(3), 1997, pp. 334-341
Ninety-one patients who had ninety-four open fractures of the tibial s
haft were randomized into two treatment groups. Fifty fractures (nine
type-I, eighteen type-II, sixteen type-IIIA, and seven type-IIIB fract
ures, according to the classification of Gustilo et al.) were treated
with nailing after reaming, and forty-four fractures (five type-I, six
teen type-II, nineteen type-IIIA, and four type-IIIB fractures) were t
reated with nailing without reaming. The average diameter of the nail
was 11.5 millimeters (range, nine to fourteen millimeters) in the grou
p treated with reaming and 9.2 millimeters (range, eight to ten millim
eters) in the group treated without reaming. Follow-up information was
adequate for forty-five patients (forty-seven fractures) who had been
managed with reaming and forty patients (forty-one fractures) who had
been managed without reaming. No clinically important differences wer
e found between the two groups with regard to the technical aspects of
the procedure or the rate of early postoperative complications. The a
verage time to union was thirty weeks (range, thirteen to seventy-two
weeks) in the group treated with reaming and twenty-nine weeks (range,
thirteen to fifty weeks) in the group treated without reaming. Four (
9 per cent) of the fractures treated with reaming and five (12 per cen
t) of the fractures treated without reaming did not unite (p = 0.73).
There were two infections in the group treated with reaming and one in
the group treated without reaming. Significantly more screws broke in
the group treated without reaming (twelve; 29 per cent) than in the g
roup treated with reaming (four; 9 per cent) (p = 0.014). There was no
difference between the two groups with regard to the frequency of bro
ken nails (two nails that had been inserted after reaming broke, compa
red with one that had been inserted without reaming). The functional o
utcome, in terms of pain in the knee, range of motion, return to work,
and recreational activity, did not differ significantly between the g
roups. We concluded that the clinical and radiographic results of nail
ing after reaming are similar to those of nailing without reaming for
fixation of open fractures of the tibial shaft, although more screws b
roke when reaming had not been done.
