Abstract:
One of the points made against nailing in radius and ulna
shaft fractures has been the loss of radial bow and its impact
on function. The aims of the study were to assess the change
in magnitude and location of the radial bow in radius and
ulna shaft fractures treated with intramedullary square nails
and to assess the impact of this change on functional
outcome, patient reported disability and the range of motion
of the forearm. We measured the magnitude of radial bow
and its location in the operated extremity and compared it to
the uninjured side in 32 adult patients treated with
intramedullary square nailing for radius and ulna shaft
fractures at our institute. The mean loss of magnitude of
maximum radial bow was 2.18 mm which was statistically
significant by both student-T test and Mann-Whitney U test
with p value less than 0.01. The location of maximum radial
bow shifted distally but was statistically insignificant. The
magnitude of maximum radial bow had a negative
correlation with DASH score that was statistically
insignificant (R=- 0.22, p=0.21). It had a positive,
statistically significant correlation to the extent of supination
in the operated extremity (R = 0.66, p = 0.0004). A loss of up
to 2mm of radial bow did not influence the functional
outcome as assessed by criteria reported by Anderson et al.
The magnitude of radial bow influenced the supination of
the forearm but not the final disability as measured by
DASH score. Intramedullary nailing did decrease the
magnitude of radial bow but a reduction of up to 2mm did
not influence the functional outcome.
