Assessment of stability of the cervical spine in blunt trauma patients: review of the literature, with presentation and preliminary results of a modified traction test protocol.
(57/271)
OBJECTIVE: To review the reported efficacy of various imaging techniques in assessing stability of the neck in blunt trauma patients, and to present the protocol and preliminary results of a modified traction test protocol. DESIGN: This is a prospective cohort study. SETTING: A regional trauma unit in Southern Ontario. PATIENTS: People with blunt-trauma injuries who came to the author's consultant practice with "C-spine not cleared" status, from January 2001 through December 2003. INTERVENTIONS: A fluoroscopically controlled test of axial traction followed by flexion/extension stressing. OUTCOME MEASURES: Radiographic confirmation of the absence of pathological motion under load. RESULTS: In 51 cases studied to date, no instabilities have been found. Four cases of minor ligamentous hypermobility have been detected, with stability confirmed and no surgery required. There have been no failures to depict the neck completely, no missed instabilities and no complications of the procedure. CONCLUSIONS: Cervical stability can be reliably confirmed with this test without any requirement for advanced imaging technology. (+info)
Evaluation and treatment of posterior neck pain in family practice.
(58/271)
Neck pain is almost universal and is a common patient complaint. Although the differential diagnosis is extensive, most symptoms are from biomechanical sources, such as axial neck pain, whiplash-associated disorder (WAD), and radiculopathy. Most symptoms abate quickly with little intervention. There is relatively little high-quality treatment evidence available, and no consensus on management of axial neck pain or radiculopathy. A number of general pain management guidelines are applicable to neck pain, and specific guidelines are available on the management of WAD. The goal of diagnosis is to identify the anatomic pain generator(s). Patient history and examination are important in distinguishing potential causes and identifying red flags. Diagnostic imaging should be ordered only when necessary because of the high incidence of asymptomatic radiographic abnormalities. First-line drug treatments include acetaminophen, cyclo-oxygenase 2-specific inhibitors, or nonsteroidal anti-inflammatory drugs. Short-term use of muscle relaxants may be considered. Opioids should be used if other treatments are ineffective and continued if improved function outweighs impairment. Adjuvant antidepressants and anticonvulsants should be considered in chronic or neuropathic pain and coincident depression. Epidural steroids should be considered only in radiculopathy. Physical modalities supported by evidence should be used. If symptoms have not resolved in 4 to 6 weeks, re-evaluation and additional workup should be considered. (+info)
Comparison of the intubating laryngeal mask airway and laryngeal tube placement during manual in-line stabilisation of the neck.
(59/271)
We compared the placement of the laryngeal tube (LT) with the intubating laryngeal mask airway (ILMA) in 51 patients whose necks were stabilised by manual in-line traction. Following induction of anaesthesia and neuromuscular blockade, the LT and ILMA were inserted consecutively in a randomised, crossover design. Using pressure-controlled ventilation (20 cmH(2)O inspiratory pressure), we measured insertion attempts, time to establish positive-pressure ventilation, tidal volume, gastric insufflation, and minimum airway pressure at which gas leaked around the cuff. Data were compared using Wilcoxon signed-rank tests; p < 0.05 was considered significant. Insertion was found to be more difficult with the LT (successful at first attempt in 16 patients) than with the ILMA (successful at first attempt in 42 patients, p < 0.0001). Time required for insertion was longer for the LT (28 [23-35] s, median [interquartile range]) than for the ILMA (20 [15-25] s, p = 0.0009). Tidal volume was less for the LT (440 [290-670] ml) than for the ILMA (630 [440-750] ml, p = 0.013). Minimum airway pressure at which gas leak occurred and incidence of gastric insufflation were similar with two devices. In patients whose necks were stabilised with manual in-line traction, insertion of the ILMA was easier and quicker than insertion of the LT and tidal volume was greater with the ILMA than the LT.

Elevated, straight-arm traction for supracondylar fractures of the humerus in children.
(60/271)
Between January 1995 and December 2000, 112 children with a closed displaced supracondylar fracture of the humerus without vascular deficit, were managed by elevated, straight-arm traction for a mean of 22 days. The final outcome was assessed using clinical (flexion-extension arc, carrying angle and residual rotational deformity) and radiographic (metaphyseal-diaphyseal angle and humerocapitellar angle) criteria. Excellent results were achieved in 71 (63%) patients, 33 (29%) had good results, 5 (4.4%) fair, and 3 (2.6%) poor. All patients with fair or poor outcomes were older than ten years of age. Elevated, straight-arm traction is safe and effective in children younger than ten years. It can be effectively used in an environment that can provide ordinary paediatric medical care and general orthopaedic expertise. The outcomes compare with supracondylar fractures treated surgically in specialist centres. (+info)
Lessons learned from cervical pseudoarthrosis in ankylosing spondylitis.
(61/271)
This case report illustrates three learning points about cervical fractures in ankylosing spondylitis, and it highlights the need to manage these patients with the neck initially stabilised in flexion. We describe a case of cervical pseudoarthrosis that is a rare occurrence after fracture of the cervical spine with ankylosing spondylitis. This went undetected until the development of myelopathic symptoms many months later. The neck was initially stabilised in flexion using tongs, and then slowly extended before anterior and posterior fixation was performed. The myelopathic symptoms resolved, and the patient had a good result at 18 months. We conclude that any increased movement of the spine after trauma in ankylosing spondylitis must be considered suspect and fully investigated. (+info)
Rush pin fixation versus traction and casting for femoral fracture in children older than seven years.
(62/271)
BACKGROUND: The optimal treatment for femoral fractures in children is controversial. The purpose of this study was to compare the results of Rush pin fixation with those of conservative treatment, and to evaluate the sequels of growth plate injury by internal fixation. METHODS: Eighteen femoral shaft fractures in 17 children who had concomitant head injury or multiple traumas were treated surgically. The mean age at operation was 9 years 3 months (range, 7 years 5 months to 11 years 1 month). One Rush pin was inserted from the tip of the greater trochanter, without reaming, to fix the fracture. Another 20 age-matched children treated by traction and casting were the control subjects. RESULTS: All the fractures united without consequences. In addition to a decrease in hospital stay with the use of the Rush pin (10 days vs. 27 days, p<0.05), fewer leg length discrepancies (4.2 mm vs. 7.1 mm, p<0.05) were also noted, compared with conservative treatment. The growth of the proximal femur after Rush pin fixation was evaluated after an average of 59 months. No femur shortening, coxa valgus, or hip dysplasia was noted. CONCLUSIONS: Intramedullary Rush pin fixation for femoral shaft fracture in children older than 7 years is a simple and reliable alternative. One narrow and non-reaming pin inserted from greater trochanter did not demonstrate femoral growth inhibition. (+info)
The effect of traction on compartment pressures during intramedullary nailing of tibial-shaft fractures. A prospective randomised trial.
(63/271)
Our aim was to study the effect of traction on the compartment pressures during intramedullary nailing of closed tibial-shaft fractures. Thirty consecutive patients with Tscherne C1 fractures were randomised into two groups. Sixteen patients underwent intramedullary nailing of the tibia with traction and 14 patients without traction. Compartment pressures were measured before the application of traction or commencement of the procedure and at the end of the procedure. The data collected was analysed using Student's t test. There was no statistically significant difference (p>0.05) in the pre-operative mean compartment pressures for both groups. The mean post-operative measurements were higher in all four compartments in the traction group (p<0.05). None of the pressures reached the critical level. These results show that traction as an aid unnecessarily increases compartment pressures. (+info)
Superior mesenteric artery syndrome following scoliosis surgery: its risk indicators and treatment strategy.
(64/271)
AIM: To investigate the risk indicators, pattern of clinical presentation and treatment strategy of superior mesenteric artery syndrome (SMAS) after scoliosis surgery. METHODS: From July 1997 to October 2003, 640 patients with adolescent scoliosis who had undergone surgical treatment were evaluated prospectively, and among them seven patients suffered from SMAS after operation. Each patient was assigned a percentile for weight and a percentile for height. Values of the 5th, 10th, 25th, 50th, 75th, and 95th percentiles were selected to divide the observations. The sagittal Cobb angle was used to quantify thoracic or thoracolumbar kyphosis. All the seven patients presented with nausea and intermittent vomiting about 5 d after operation. An upper gastrointestinal barium contrast study showed a straight-line cutoff at the third portion of the duodenum representing extrinsic compression by the superior mesenteric artery (SMA). RESULTS: The value of height in the seven patients with SMAS was above the mean of sex- and age-matched normal population, and the height percentile ranged from 5% to 50%. On the contrary, the value of weight was below the mean of normal population with the weight percentile ranging from 5% to 25%. Among the seven patients, four had a thoracic hyperkyphosis ranging from 55 degrees to 88 degrees (average 72 degrees), two had a thoracolumbar kyphosis of 25 degrees and 32 degrees respectively. The seven patients were treated with fasting, antiemetic medication, and intravenous fluids infusion. Reduction or suspense of traction was adopted in three patients with SMAS during halo-femoral traction after anterior release of scoliosis. All the patients recovered completely with no sequelae. No one required operative intervention with a laparotomy. CONCLUSION: Height percentile < 50%, weight percentile < 25%, sagittal kyphosis, heavy and quick halo-femoral traction after spinal anterior release are the potential risk indicators for SMAS in patients undergoing correction surgery for adolescent scoliosis.
