The aim of this study was to investigate the clinical and radiographic
outcomes of microendoscopic laminotomy in patients with lumbar stenosis
and concurrent degenerative spondylolisthesis (DS), and to determine
the effect of this procedure on spinal stability. A total of 304 consecutive patients with single-level lumbar
DS with concomitant stenosis underwent microendoscopic laminotomy
without fusion between January 2004 and December 2010. Patients
were divided into two groups, those with and without advanced DS
based on the degree of spondylolisthesis and dynamic instability. A
total of 242 patients met the inclusion criteria. There were 101
men and 141 women. Their mean age was 68.1 years (46 to 85). Outcome
was assessed using the Japanese Orthopaedic Association and Roland
Morris Disability Questionnaire scores, a visual analogue score
for pain and the Short Form Health-36 score. The radiographic outcome
was assessed by measuring the slip and the disc height. The clinical
and radiographic parameters were evaluated at a mean follow-up of
4.6 years (3 to 7.5).Aims
Patients and Methods
The purpose of this study was to evaluate the
long-term outcome of adults with spina bifida cystica (SBC) who
had been treated either operatively or non-operatively for scoliosis
during childhood. We reviewed 45 patients with a SBC scoliosis (Cobb angle ≥ 50º)
who had been treated at one of two children’s hospitals between
1991 and 2007. Of these, 34 (75.6%) had been treated operatively
and 11 (24.4%) non-operatively. After a mean follow-up of 14.1 years
(standard deviation ( Although patients in the two groups were demographically similar,
those who had undergone surgery had a larger mean Cobb angle (88.0º
( Spinal fusion in SBC scoliosis corrects coronal deformity and
stops progression of the curve but has no clear effect on HRQOL. Cite this article:
Cardiac disease in patients with ankylosing spondylitis
(AS) has previously been studied but not in patients with a kyphosis
or in those who have undergone an operation to correct it. The aim of this study was to measure the post-operative changes
in cardiac function of patients with an AS kyphosis after pedicle
subtraction osteotomy (PSO). The original cohort consisted of 39 patients (33 men, six women).
Of these, four patients (two men, two women) were lost to follow-up
leaving 35 patients (31 men, four women) to study. The mean age
of the remaining patients was 37.4 years (22.3 to 47.8) and their
mean duration of AS was 17.0 years (4.6 to 26.4). Echocardiographic measurements,
resting heart rate (RHR), physical function score (PFS), and full-length
standing spinal radiographs were obtained before surgery and at
the two-year follow-up. The mean pre-operative RHR was 80.2 bpm (60.6 to 112.3) which
dropped to a mean of 73.7 bpm (60.7 to 90.6) at the two-year follow-up
(p = 0.0000). Of 15 patients with normal ventricular function pre-operatively,
two developed mild left ventricular diastolic dysfunction (LVDD)
at the two-year follow-up. Of 20 patients with mild LVDD pre-operatively
only five had this post-operatively. Overall, 15 patients had normal
LV diastolic function before their operation and 28 patients had
normal LV function at the two-year follow-up. The clinical improvement was 15 out of 20 (75.0%): cardiac function
in patients with AS whose kyphosis was treated by PSO was significantly
improved. Cite this article:
We have studied 180 patients (128 men and 52 women) who had undergone lumbar discectomy at a mean of 25.4 years (20 to 32) after operation. Pre-operatively, most patients (70 patients; 38.9%) had abnormal reflexes and/or muscle weakness in the leg (96 patients; 53.3%). At follow-up 42 patients (60%) with abnormal reflexes pre-operatively had fully recovered and 72 (75%) with pre-operative muscle impairment had normal muscle strength. When we looked at patient-reported outcomes, we found that the Short form-36 summary scores were similar to the aged-matched normative values. No disability or minimum disability on the Oswestry disability index was reported by 136 patients (75.6%), and 162 (90%) were satisfied with their operation. The most important predictors of patients’ self-reported positive outcome were male gender and higher educational level. No association was detected between muscle recovery and outcome. Most patients who had undergone lumbar discectomy had long-lasting neurological recovery. If the motor deficit persists after operation, patients can still expect a long-term satisfactory outcome, provided that they have relief from pain immediately after surgery.
