further
investigate
the
influence
of
comorbidities,
larger
pro-
spective
studies
are
needed.
Our
study
has
several
limitations.
Firstly,
data
were
ac-
quired
retrospectively,
and
therefore,
no
randomization
to
one
of
the
surgical
treatments
was
conducted.
A
consultant
or-
thopedic
surgeon
decided,
based
on
personal
preferences,
which
operation
should
be
performed.
Furthermore,
owing
to
the
retrospective
design,
the
only
available
functional
outcome
parameter
was
the
ROM
in
abduction.
In
many
cases
no
standardized
scores
or
pain
assessments
were
available
and,
therefore,
could
not
be
included
in
the
study.
Secondly,
different
surgeons
performed
the
surgical
pro-
cedures;
however,
all
procedures
were
performed
by
experienced
orthopedic
surgeons.
Thirdly,
magnetic
resonance
imaging
was
not
available
for
a
sufficient
number
of
patients
to
correlate
imaging
findings
and
surgical
success
rates.
Fourthly,
the
sample
size
was
limited
to
59
patients
with
a
substantial
recruiting
period
of
14
years.
Given
the
sample
size
of
59
patients,
the
influence
of
potential
risk
factors
might
have
been
underestimated.
However,
this
is
still
one
of
the
largest
studies
on
treatment
of
septic
shoulder
infections
cur-
rently
available
in
the
literature.
Based
on
the
numbers
available,
our
findings
might
be
helpful
for
surgical
deci-
sion
making
in
clinical
practice.
Future
studies
with
larger
sample
sizes
including
prospective
randomized-controlled
trials
are
needed
to
confirm
the
current
findings.
Conclusion
This
study
demonstrated
that
open
arthrotomy
was
a
more
effective
treatment
method
in
septic
arthritis
of
the
shoul-
der,
with
lower
reinfection
rates
and
a
comparable
functional
outcome.
Furthermore,
we
could
identify
S
aureus
and
the
CCI
as
an
independent
risk
factor
for
re-
currence
of
infection.
