Considerable concern has been expressed about the type and level of ex
ercise that are safe for women with osteopenia and osteoporosis; howev
er, published information on the effect of golfing on the osteoporotic
spine is meager. We describe three postmenopausal patients with acute
compression fractures of the vertebrae that occurred during midswing
while golfing. These healthy, active women were long-term golfers; the
ir ages at the time of the trauma were 63, 58, and 66 years. In one pa
tient (case 1), osteoporosis was diagnosed before the golf-related inj
ury. The two other patients (cases 2 and 3) sought medical attention a
fter the trauma and were found to have osteoporosis. The bone mineral
density of the lumbar vertebrae (L2-4) in the three patients at the ti
me of or shortly after the trauma was as follows: case 1, 0.77 g/cm2 (
3rd percentile of normal, corrected for age); case 2, 0.63 g/cm2 (less
than 1st percentile of normal, corrected for age); and case 3, 0.69 g
/cm2 (2nd percentile of normal, corrected for age). These findings rai
se the issue of the safety of golfing for women with previously diagno
sed osteoporosis and for those with predisposing risk factors for the
disease. Research studies of the kinematics and kinetics of the spine
during the golf swing should be conducted. In the interim, a rigid bac
k support for golfers with osteoporosis may be helpful until more conc
lusive evidence is available from controlled trials.
