The isolated fracture of the ulnar shaft. Treatment without immobilization
FH Pollock, AM Pankovich, JJ Prieto and M Lorenz
The isolated fracture of the ulnar shaft is notorious for prolonged healing
time. Over a twenty-seven-month period, seventy-one such fractures were
treated at our institution. The initial twelve fractures were immobilized
with the standard axilla-to-palm plaster cast. They had an average healing
time of 10.5 weeks and a non-union rate of 8 per cent. The remaining
fifty-nine fractures were treated without a cast or with a cast or splint
for no longer than two weeks after injury and then mobilization as
tolerated. In this group the average healing time was 6.7 weeks and there
were no non-unions. The motion at the wrist and elbow was always regained,
and the average loss of forearm rotation was 5 degrees.
