Spinal stenosis and disc herniation are the two
most frequent causes of lumbosacral nerve root compression. This
can result in muscle weakness and present with or without pain. The
difficulty when managing patients with these conditions is knowing
when surgery is better than
Rates of mortality as high as 25% to 30% have been described
following fractures of the odontoid in the elderly population. The
aim of this study was to examine whether easily identifiable variables
present on admission are associated with mortality. A consecutive series of 83 elderly patients with a fracture of
the odontoid following a low-impact injury was identified retrospectively.
Data that were collected included demographics, past medical history
and the results of blood tests on admission. Radiological investigations
were used to assess the Anderson and D’Alonzo classification and
displacement of the fracture. The mean age was 82.9 years (65 to
101). Most patients (66; 79.5%) had a type 2 fracture. An associated
neurological deficit was present in 11 (13.3%). All were treated
conservatively; 80 (96.4%) with a hard collar and three (3.6%) with
halo vest immobilisation.Aims
Patients and Methods
We performed a retrospective, comparative study of elderly patients
with an increased risk from anaesthesia who had undergone either
anterior screw fixation (ASF) or halo vest immobilisation (HVI)
for a type II odontoid fracture. A total of 80 patients aged 65 years or more who had undergone
either ASF or HVI for a type II odontoid fracture between 1988 and
2013 were reviewed. There were 47 women and 33 men with a mean age
of 73 (65 to 96; standard deviation 7). All had an American Society
of Anesthesiologists score of 2 or more.Aims
Patients and Methods
Lumbar disc herniation (LDH) is uncommon in youth
and few cases are treated surgically. Very few outcome studies exist
for LDH surgery in this age group. Our aim was to explore differences
in gender in pre-operative level of disability and outcome of surgery
for LDH in patients aged ≤ 20 years using prospectively collected
data. From the national Swedish SweSpine register we identified 180
patients with one-year and 108 with two-year follow-up data ≤ 20
years of age, who between the years 2000 and 2010 had a primary
operation for LDH. Both male and female patients reported pronounced impairment
before the operation in all patient reported outcome measures, with
female patients experiencing significantly greater back pain, having
greater analgesic requirements and reporting significantly inferior
scores in EuroQol (EQ-5D-index), EQ-visual analogue scale, most aspects
of Short Form-36 and Oswestry Disabilities Index, when compared
with male patients. Surgery conferred a statistically significant
improvement in all registered parameters, with few gender discrepancies.
Quality of life at one year following surgery normalised in both
males and females and only eight patients (4.5%) were dissatisfied with
the outcome. Virtually all parameters were stable between the one-
and two-year follow-up examination. LDH surgery leads to normal health and a favourable outcome in
both male and female patients aged 20 years or younger, who failed
to recover after non-operative management. Cite this article:
We reviewed 34 consecutive patients (18 female-16 male) with
isthmic spondylolysis and grade I to II lumbosacral spondylolisthesis
who underwent in situ posterolateral arthodesis between the L5 transverse
processes and the sacral ala with the use of iliac crest autograft.
Ten patients had an associated scoliosis which required surgical correction
at a later stage only in two patients with idiopathic curves unrelated
to the spondylolisthesis. No patient underwent spinal decompression or instrumentation
placement. Mean surgical time was 1.5 hours (1 to 1.8) and intra-operative
blood loss 200 ml (150 to 340). There was one wound infection treated
with antibiotics but no other complication. Radiological assessment
included standing posteroanterior and lateral, Ferguson and lateral flexion/extension
views, as well as CT scans. Aims
Methods
We undertook a prospective non-randomised radiological study
to evaluate the preliminary results of using magnetically-controlled
growing rods (MAGEC System, Ellipse technology) to treat children
with early-onset scoliosis. Between January 2011 and January 2015, 19 children were treated
with magnetically-controlled growing rods (MCGRs) and underwent
distraction at three-monthly intervals. The mean age of our cohort
was 9.1 years (4 to 14) and the mean follow-up 22.4 months (5.1
to 35.2). Of the 19 children, eight underwent conversion from traditional growing
rods. Whole spine radiographs were carried out pre- and post-operatively:
image intensification was used during each lengthening in the outpatient
department. The measurements evaluated were Cobb angle, thoracic kyphosis,
proximal junctional kyphosis and spinal growth from T1 to S1.Aims
Patients and Methods
This study aimed to determine the relationship between pedicle-lengthening
distance and bulge-canal volume ratio in cases of lumbar spinal
stenosis, to provide a theoretical basis for the extent of lengthening
in pedicle-lengthening osteotomies. Three-dimensional reconstructions of CT images were performed
for 69 patients (33 men and 36 women) (mean age 49.96 years; 24
to 81). Simulated pedicle-lengthening osteotomies and disc bulge
and spinal canal volume calculations were performed using Mimics
software. Aims
Methods
The authors present the results of a cohort study of 60 adult
patients presenting sequentially over a period of 15 years from
1997 to 2012 to our hospital for treatment of thoracic and/or lumbar
vertebral burst fractures, but without neurological deficit. All patients were treated by early mobilisation within the limits
of pain, early bracing for patient confidence and all progress in
mobilisation was recorded on video. Initial hospital stay was one
week. Subsequent reviews were made on an outpatient basis. Aims
Method
Back pain is a common symptom in children and
adolescents. Here we review the important causes, of which defects
and stress reactions of the pars interarticularis are the most common
identifiable problems. More serious pathology, including malignancy
and infection, needs to be excluded when there is associated systemic
illness. Clinical evaluation and management may be difficult and
always requires a thorough history and physical examination. Diagnostic
imaging is obtained when symptoms are persistent or severe. Imaging
is used to reassure the patient, relatives and carers, and to guide
management. Cite this article:
Whether to combine spinal decompression with
fusion in patients with symptomatic lumbar spinal stenosis remains
controversial. We performed a cohort study to determine the effect
of the addition of fusion in terms of patient satisfaction after
decompressive spinal surgery in patients with and without a degenerative spondylolisthesis. The National Swedish Register for Spine Surgery (Swespine) was
used for the study. Data were obtained for all patients in the register
who underwent surgery for stenosis on one or two adjacent lumbar
levels. A total of 5390 patients fulfilled the inclusion criteria
and completed a two-year follow-up. Using multivariable models the
results of 4259 patients who underwent decompression alone were
compared with those of 1131 who underwent decompression and fusion.
The consequence of having an associated spondylolisthesis in the
operated segments pre-operatively was also considered. At two years there was no significant difference in patient satisfaction
between the two treatment groups for any of the outcome measures,
regardless of the presence of a pre-operative spondylolisthesis.
Moreover, the proportion of patients who required subsequent further
lumbar surgery was also similar in the two groups. In this large cohort the addition of fusion to decompression
was not associated with an improved outcome. Cite this article:
Adolescent idiopathic scoliosis affects about
3% of children. Non-operative measures are aimed at altering the natural
history to maintain the size of the curve below 40° at skeletal
maturity. The application of braces to treat spinal deformity pre-dates
the era of evidence-based medicine, and there is a paucity of irrefutable
prospective evidence in the literature to support their use and
their effectiveness has been questioned. This review considers this evidence. The weight of the evidence
is in favour of bracing over observation. The most recent literature
has moved away from addressing this question, and instead focuses
on developments in the design of braces and ways to improve compliance. Cite this article:
We have treated 15 patients with massive lumbar disc herniations non-operatively. Repeat MR scanning after a mean 24 months (5 to 56) showed a dramatic resolution of the herniation in 14 patients. No patient developed a cauda equina syndrome. We suggest that this condition may be more benign than previously thought.
Conventional growing rods are the most commonly
used distraction-based devices in the treatment of progressive early-onset
scoliosis. This technique requires repeated lengthenings with the
patient anaesthetised in the operating theatre. We describe the
outcomes and complications of using a non-invasive magnetically
controlled growing rod (MCGR) in children with early-onset scoliosis.
Lengthening is performed on an outpatient basis using an external remote
control with the patient awake. Between November 2009 and March 2011, 34 children with a mean
age of eight years (5 to 12) underwent treatment. The mean length
of follow-up was 15 months (12 to 18). In total, 22 children were
treated with dual rod constructs and 12 with a single rod. The mean
number of distractions per patient was 4.8 (3 to 6). The mean pre-operative
Cobb angle was 69° (46° to 108°); this was corrected to a mean 47°
(28° to 91°) post-operatively. The mean Cobb angle at final review
was 41° (27° to 86°). The mean pre-operative distance from T1 to
S1 was 304 mm (243 to 380) and increased to 335 mm (253 to 400)
in the immediate post-operative period. At final review the mean distance
from T1 to S1 had increased to 348 mm (260 to 420). Two patients developed a superficial wound infection and a further
two patients in the single rod group developed a loss of distraction.
In the dual rod group, one patient had pull-out of a hook and one
developed prominent metalwork. Two patients had a rod breakage;
one patient in the single rod group and one patient in the dual
rod group. Our early results show that the MCGR is safe and effective
in the treatment of progressive early-onset scoliosis with the avoidance
of repeated surgical lengthenings. Cite this article:
This prospective multicentre study was undertaken
to determine segmental movement, disc height and sagittal alignment
after total disc replacement (TDR) in the lumbosacral spine and
to assess the correlation of biomechanical properties to clinical
outcomes. A total of 173 patients with degenerative disc disease and low
back pain for more than one year were randomised to receive either
TDR or multidisciplinary rehabilitation (MDR). Segmental movement
in the sagittal plane and disc height were measured using distortion
compensated roentgen analysis (DCRA) comparing radiographs in active flexion
and extension. Correlation analysis between the range of movement
or disc height and patient-reported outcomes was performed in both
groups. After two years, no significant change in movement in the
sagittal plane was found in segments with TDR or between the two
treatment groups. It remained the same or increased slightly in
untreated segments in the TDR group and in this group there was
a significant increase in disc height in the operated segments.
There was no correlation between segmental movement or disc height
and patient-reported outcomes in either group. In this study, insertion of an intervertebral disc prosthesis
TDR did not increase movement in the sagittal plane and segmental
movement did not correlate with patient-reported outcomes. This
suggests that in the lumbar spine the movement preserving properties
of TDR are not major determinants of clinical outcomes. Cite this article:
Between 1993 and 2008, 41 patients underwent total coccygectomy for coccydynia which had failed to respond to six months of conservative management. Of these, 40 patients were available for clinical review and 39 completed a questionnaire giving their evaluation of the effect of the operation. Excellent or good results were obtained in 33 of the 41 patients, comprising 18 of the 21 patients with coccydynia due to trauma, five of the eight patients with symptoms following childbirth and ten of 12 idiopathic onset. In eight patients the results were moderate or poor, although none described worse pain after the operation. The only post-operative complication was superficial wound infection which occurred in five patients and which settled fully with antibiotic treatment. One patient required re-operation for excision of the distal cornua of the sacrum. Total coccygectomy offered satisfactory relief of pain in the majority of patients regardless of the cause of their symptoms.
We reviewed 15 consecutive patients, 11 women and four men, with a mean age of 48.7 years (37.3 to 62.6), who between July 2004 and August 2007 had undergone percutaneous sacroiliac fusion using hollow modular anchorage screws filled with demineralised bone matrix. Each patient was carefully assessed to exclude other conditions and underwent pre-operative CT and MR scans. The diagnosis of symptomatic sacroiliac disease was confirmed by an injection of local anaesthetic and steroid under image intensifier control. The short form-36 questionnaire and Majeed’s scoring system were used for pre- and post-operative functional evaluation. Post-operative radiological evaluation was performed using plain radiographs. Intra-operative blood loss was minimal and there were no post-operative clinical or radiological complications. The mean follow-up was for 17 months (9 to 39). The mean short form-36 scores improved from 37 (23 to 51) to 80 (67 to 92) for physical function and from 53 (34 to 73) to 86 (70 to 98) for general health (p = 0.037). The mean Majeed’s score improved from 37 (18 to 54) pre-operatively to 79 (63 to 96) post-operatively (p = 0.014). There were 13 good to excellent results. The remaining two patients improved in short form-36 from a mean of 29 (26 to 35) to 48 (44 to 52). Their persistent pain was probably due to concurrent lumbar pathology. We conclude that percutaneous hollow modular anchorage screws are a satisfactory method of achieving sacroiliac fusion.
We investigated the pre-operative and one-year post-operative health-related quality of life (HRQoL) outcome by using a Euroqol (EQ-5D) questionnaire in 230 patients who underwent surgery for lumbar spinal stenosis. Data were obtained from the National Swedish Registry for operations on the lumbar spine between 2001 and 2002. We analysed the pre- and postoperative quality of life data, age, gender, smoking habits, pain and walking ability. The relative differences were compared to a Swedish EQ-5D population survey. The mean age of the patients was 66 years, and there were 123 females (53%). Before the operation 62 (27%) of the patients could walk more than 500 m. One year after the operation 150 (65%) were able to walk 500 m or more. The mean EQ-5D score improved from 0.36 to 0.64, and the HRQoL improved in 184 (80%) of the patients. However, they did not reach the level reported by a matched population sample (mean difference 0.18). Women had lower pre- and post-operative EQ-5D scores than men. Severe low back pain was a predictor for a poor outcome.
We have assessed whether an epidural steroid injection is effective in the treatment of symptoms due to compression of a nerve root in the lumbar spine by carrying out a prospective, randomised, controlled trial in which patients received either an epidural steroid injection or an intramuscular injection of local anaesthetic and steroid. We assessed a total of 93 patients according to the Oxford pain chart and the Oswestry disability index and followed up for a minimum of two years. All the patients had been categorised as potential candidates for surgery. There was a significant reduction in pain early on in those having an epidural steroid injection but no difference in the long term between the two groups. The rate of subsequent operation in the groups was similar.
We investigated the pre-operative and one-year post-operative health-related quality of life (HRQOL) outcome by using a Euroqol (EQ-5D) questionnaire in 263 patients who had undergone surgery for herniation of a lumbar disc. Data from the National Swedish Register for lumbar spinal surgery between 2001 and 2002 were used and, in addition, a comparison between our cohort and a Swedish EQ-5D population survey was performed. We analysed the pre- and post-operative quality of life data, age, gender, smoking habits, pain and walking capacity. The mean age of the patients was 42 years (20 to 66); 155 (59%) were men and 69 (26%) smoked. Pre-operatively, 72 (17%) could walk at least 1 km compared with 200 (76%) postoperatively. The mean EQ-5D score improved from 0.29 to 0.70, and the HRQOL improved in 195 (74%) of the patients. The pre-operative score did not influence the post-operative score. In most patients, all five EQ-5D dimensions improved, but did not reach the level reported by an age- and gender-matched population sample (mean difference 0.17). Predictors for poor outcome were smoking, a short pre-operative walking distance, and a long history of back pain.
