Indication Variability in Degenerative Lumbar Spine Surgery: A Four-nation Survey.

2017

Electronic survey.The aim of this study was to identify the international nuances in surgical treatment patterns for severals lumbar degenerative conditions, specifically, to identify differences in responses in each country groupand different treatment trends across countries.Significant variations in treatment of lumbar degenerative conditions exist among spine surgeons, related to the lack of established consensus in the literature.An online survey with preformulated answers was submitted to 52 orthopedic surgeons, 50 neurosurgeons from four different countries (United States, France, Spain, and Germany) regarding five vignette-cases. Cases included: multilevel stenosis, monolevel stenos…

Development of scoliosis in myelomeningocele. Differences in the history caused by idiopathic pattern.

1993

The natural history of scoliosis in the literature concerning the idiopathic and neuromuscular scoliosis in myelomeningocele patients (MMC) are compared to our own results in 12 patients with MMC and 89 patients operated because of an idiopathic scoliosis. According to known experiences the natural history of scoliosis in MMC is progression even after the end of growth. The chance of developing a scoliosis increases with the patients, age and the level of the lesion. The higher the level of paralysis the more common is a spinal deformity. In literature the progression rate of MMC scoliosis is 2.5-3.5 degrees per year, with the idiopathic pattern 0.5-0.65 degrees per year after end of growth…

Muscle activity patterns and spinal shrinkage in office workers using a sit–stand workstation versus a sit workstation

2016

Reducing sitting time by means of sit-stand workstations is an emerging trend, but further evidence is needed regarding their health benefits. This cross-sectional study compared work time muscle activity patterns and spinal shrinkage between office workers (aged 24-62, 58.3% female) who used either a sit-stand workstation (Sit-Stand group, n = 10) or a traditional sit workstation (Sit group, n = 14) for at least the past three months. During one typical workday, muscle inactivity and activity from quadriceps and hamstrings were monitored using electromyography shorts, and spinal shrinkage was measured using stadiometry before and after the workday. Compared with the Sit group, the Sit-Stan…

Selective activation of shoulder, trunk, and arm muscles: A comparative analysis of different push-up variants

2015

Context The push-up is a widely used exercise for upper limb strengthening that can be performed with many variants. A comprehensive analysis of muscle activation during the ascendant phase (AP) and descendant phase (DP) in different variants could be useful for trainers and rehabilitators. Objective To obtain information on the effect of different push-up variants on the electromyography (EMG) of a large sample of upper limb muscles and to investigate the role of the trunk and abdomen muscles during the AP and DP. Design Cross-sectional study. Setting University laboratory. Patients or Other Participants Eight healthy, young volunteers without a history of upper extremity or spine injury.…

The progression of paraspinal muscle recruitment intensity in localized and global strength training exercises is not based on instability alone.

2011

Abstract Colado JC, Pablos C, Chulvi-Medrano I, Garcia-Masso X, Flandez J, Behm DG. The progression of paraspinal muscle recruitment intensity in localized and global strength training exercises is not based on instability alone. Objective To evaluate electromyographic activity of several paraspinal muscles during localized stabilizing exercises and multijoint or global stabilizing exercises. Design Cross-sectional counterbalanced repeated measures. Setting Research laboratory. Participants Volunteers (N=25) without low-back pain. Intervention Subjects performed (1) localized stabilizing exercises (callisthenic exercises with only body weight as resistance): static lumbar extension, stable …

Progression of untreated mild thoracic Scheuermann's kyphosis – Radiographic and functional assessment after mean follow-up of 46 years

2017

There is no data available on the radiographic development of the Scheuermann's deformity. Our purpose was to investigate radiographic deformity progression and the relation between kyphosis progression and clinical outcome in patients with untreated Scheuermann's kyphosis.Thoracic kyphosis (Th4-Th12) was measured from standing lateral radiographs in 19 patients at baseline and after mean 46-year follow-up. Mean age at baseline was 19.2 and at follow-up 64.7 years. At follow-up, height, weight, hand grip strength, and hamstring tightness were measured, and sit-to-stand and walking tests were performed. Additionally general health and quality of life questionnaires were administered.The mean…

Strength training and stretching versus stretching only in the treatment of patients with chronic neck pain: a randomized one-year follow-up study

2008

Objective: To compare the effectiveness of a 12-month home-based combined strength training and stretching programme against stretching alone in the treatment of chronic neck pain. Design: A randomized follow-up study. Participants: One hundred and one patients with chronic non-specific neck pain were randomized in two groups. Intervention: The strength training and stretching group was supported by 10 group training sessions and the stretching group was instructed to perform stretching exercises only as instructed in one group session. Main outcome measurements: Neck pain, disability, neck muscle strength and mobility of cervical spine were measured before and after the intervention. Resu…

Fatty replacement of bone marrow after radiation therapy for Hodgkin disease: Quantification with chemical shift imaging

1993

The authors studied the long-term fatty replacement of bone marrow in 23 patients who had received radiation therapy for Hodgkin disease, with T1-weighted magnetic resonance imaging and quantitative chemical shift imaging. T1-weighted images revealed a mostly homogeneous high-signal-intensity pattern, in contrast to the hypointense pattern of nonirradiated marrow. The degree of fatty replacement was objectively assessed with chemical shift imaging, comparing patients to age-matched healthy volunteers. The authors found an increase in relative fat signal of 37% in the thoracic spine and 34% in the lumbar spine. The relative fat signal of nonirradiated pelvic and femoral marrow was decreased …

Repeated sugammadex reversal of muscle relaxation during lumbar spine surgery with intraoperative neurophysiological multimodal monitoring

2016

Intraoperative neurophysiological monitoring during spine surgery is usually acomplished avoiding muscle relaxants. A case of intraoperative sugammadex partial reversal of the neuromuscular blockade allowing adequate monitoring during spine surgery is presented. A 38 year-old man was scheduled for discectomy and vertebral arthrodesis throughout anterior and posterior approaches. Anesthesia consisted of total intravenous anesthesia plus rocuronium. Intraoperatively monitoring was needed, and the muscle relaxant reverted twice with low dose sugammadex in order to obtain adequate responses. The doses of sugammadex used were conservatively selected (0.1 mg/kg boluses increases, total dose neede…
