Repeated lumbar spine surgery has been associated with inferior clinical outcomes. This study aimed to examine and quantify the impact of this association in a national clinical register cohort. This is a population-based study from the Norwegian Registry for Spine surgery (NORspine). We included 26,723 consecutive cases operated for lumbar spinal stenosis or lumbar disc herniation from January 2007 to December 2018. The primary outcome was the Oswestry Disability Index (ODI), presented as the proportions reaching a patient-acceptable symptom state (PASS; defined as an ODI raw score ≤ 22) and ODI raw and change scores at 12-month follow-up. Secondary outcomes were the Global Perceived Effect scale, the numerical rating scale for pain, the EuroQoL five-dimensions health questionnaire, occurrence of perioperative complications and wound infections, and working capability. Binary logistic regression analysis was conducted to examine how the number of previous operations influenced the odds of not reaching a PASS.Aims
Methods
A total of 30 patients with thoracolumbar/lumbar adolescent idiopathic
scoliosis (AIS) treated between 1989 and 2000 with anterior correction
and fusion surgery using dual-rod instrumentation were reviewed. Radiographic parameters and clinical outcomes were compared among
patients with lowest instrumented vertebra (LIV) at the lower end
vertebra (LEV; EV group) (n = 13) and those treated by short fusion
(S group), with LIV one level proximal to EV (n = 17 patients). Aims
Patients and Methods
Dysphagia is a common complication of anterior
surgery of the cervical spine. The incidence of post-operative dysphagia
may be as high as 71% within the first two weeks after surgery,
but gradually decreases during the following months. However, 12%
to 14% of patients may have some persistent dysphagia one year after
the procedure. It has been shown that female gender, advanced age,
multilevel surgery, longer operating time and severe pre-operative
neck pain may be risk factors. Although the aetiology remains unclear
and is probably multifactorial, proposed causes include oesophageal
retraction, prominence of the cervical plate and prevertebral swelling.
Recently, pre-operative tracheal traction exercises and the use
of retropharyngeal steroids have been proposed as methods of reducing
post-operative dysphagia. We performed a systematic review to assess the incidence, aetiology,
risk factors, methods of assessment and management of dysphagia
following anterior cervical spinal surgery. Cite this article:
This is a prospective randomised study comparing
the clinical and radiological outcomes of uni- and bipedicular balloon
kyphoplasty for the treatment of osteoporotic vertebral compression
fractures. A total of 44 patients were randomised to undergo either
uni- or bipedicular balloon kyphoplasty. Self-reported clinical
assessment using the Oswestry Disability Index, the Roland-Morris
Disability questionnaire and a visual analogue score for pain was undertaken
pre-operatively, and at three and twelve months post-operatively.
The vertebral height and kyphotic angle were measured from pre-
and post-operative radiographs. Total operating time and the incidence
of cement leakage was recorded for each group. Both uni- and bipedicular kyphoplasty groups showed significant
within-group improvements in all clinical outcomes at three months
and twelve months after surgery. However, there were no significant
differences between the groups in all clinical and radiological
outcomes. Operating time was longer in the bipedicular group (p <
0.001). The incidence of cement leakage was not significantly different
in the two groups (p = 0.09). A unipedicular technique yielded similar clinical and radiological
outcomes as bipedicular balloon kyphoplasty, while reducing the
length of the operation. We therefore encourage the use of a unipedicular
approach as the preferred surgical technique for the treatment of
osteoporotic vertebral compression fractures. Cite this article:
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.
