60. Retrograde ejaculation ALIF⢠The underlying mechanism of the dysfunction is the
inability of the internal vesical sphincter to contract
during ejaculation, resulting in retrograde flow of semen
to the urinary bladder.[13] As the muscle is innervated by
the superior hypogastric plexus, i.e., a thin,
retroperitoneal plexus of nerves overlying the
lumbosacral junction, damage to the plexus during (or
after) ALIF can denervate the bladder neck

FDA Issues Warning Regarding Off-Label
Use of rhBMPBY LAUREN UZDIENSKI,
JULY 7, 2008
Last week the FDA released a public
health notification regarding the off-
label use of of rhBMP (InFuse, OP-1)
in the cervical spine. The agency says
that over the past four years there
have been at least 38 reports of
complications associated with using
BMP in unapproved cervical fusion
cases, ranging from difficulty
swallowing, breathing or speaking to
severe dysphagia.
Most reported complications occurred
between two and 14 days following
surgery. Treatments included
respiratory support with intubation,
anti-inflammatory medication,
tracheotomy and most commonly
second surgeries to drain the surgical
site. The seriousness of the
complications was correlated with the
anatomical proximity of the cervical
spine to airway structures. The FDA
adds, "The mechanism of action is
unknown, and characteristics of
patients at increased risk have not
been identified."
