1. In the coronal plane
2. In the sagittal plane
Regional
Segmental

This is assessed by the relationship of
the C7 plump line to the sacrum in the
coronal and sagittal planes

TREATMENT
OPTIONS

Four clinically relevant key questions were
addressed in this study :
Review article
Surgery for adult spondylolisthesis: a systematic
review of the evidence
Tobias L. Schulte et al, Eur. Spine 2016

A.
 Is surgery more successful
 than conservative treatment
in relation
to pain and function
in adult patients
with isthmic SL?

B.
 Is surgery more successful
in relation
in adult patients
with degenerative SL?

C.
 Is instrumented fusion
with decompression
more successful
in relation
 than decompression alone
in adult patients with
degenerative SL
and spinal canal stenosis?

D.
 Is instrumented fusion with reduction
more successful
in relation to pain and function
 than instrumented fusion
without reduction
in adult patients with isthmic
or degenerative SL?

1. In adults with isthmic SL,
 surgery appears to be
better in relation to
pain and function
(poor evidence).

2. In adults with degenerative SL,
 surgery appears
to be better in relation
(good evidence).

3. In adults with degenerative SL and
spinal stenosis,
 instrumented fusion
with decompression appears
to be more successful
in relation to
pain and function
 than decompression alone
(poor evidence).

4. In adults with isthmic
or degenerative SL,
 reduction and
instrumented fusion
does not appear
to be more successful in relation
 than instrumented fusion
without reduction
(moderate evidence)

Primary
degenerative
scoliosis
(‘‘de novo’’
form), mostly
located in the
thoracolumbar
or lumbar spine
Grubb SA, et al (1992)
Aebi M. (2005)

1. Body deformity
2. Pain
3. Neurological
disorders
Main problems

Automatic
fusion
Muscles – Ligaments
S-I joints

Neurological disorders
1. Lumbar canal stenosis
2. Foraminal stenosis

Purposes of the operative treatment
I. Prevention of progression
II. Maintenance of lumbar lordosis
III. Restoring global balance
IV. To reduce or to relieve the pain
V. To anticipate the neurological deficit

Key points
Sagittal imbalance
is poorly tolerated
in elderly scoliosis
patients
Timothy Kuklo, Spine 2006

• A fusion should not
be stopped adjacent
to a degenerated
segment

• Intervetebral cages

Overall gives the best clinical results

This meta-analysis made
 no recommendation for which specific type of
surgery is the best
and
 which surgical technique should be selected
for different patients
because
 the circumstances surrounding each patient
are highly complex.
Review article
Surgical treatments for degenerative lumbar scoliosis:
a meta analysis
Guohua Wang et al, Eur. Spine 2015
Cont.

This meta analysis included a study that
found no significant differences in
 Roland–Morris score, Oswestry score,
and
 patients’ satisfaction between patients who
 underwent isolated decompression,
 short fusion,
and
 long fusion surgery
Cont.
Transfeldt EE, et al, Spine 1976

One study compared
 the clinical outcome
 recurrent leg pain
 complications between isolated
decompression and decompression plus
limited fusion
revealed that
 recurrent leg pain occurred significantly more
often in patients within 6 months
 post isolated decompression.
Cont.
Daubs MD,, et al, Evid Based Spine Care J. 2012

Despite a high rate of complications, this
review demonstrates that surgery
 is an effective and reasonable treatment
intervention for severe DLS
and
 ultimately improves spine function and
deformity.
Cont.

This review also suggests
 that large scale,
 high quality studies
 with long term follow-up
are needed
to provide more reliable
evidence for future evaluation.

Key point
for the successful
operative treatment
of the adult
spinal deformity
is the restoration
of the
sagittal balance.
