A simple analysis model simulating the correlation of cervical traction force with the pressure in the cervical nucleus pulposus.

OBJECTIVE: To design a simple model for analyzing the correlation between the changes in cervical traction force and that of the pressure in the cervical nucleus pulposus. METHODS: Multiple non-linear mathematical models were established by means of regression analysis to calculate the correlation coefficient and variance, and the capacity of each model to predict the changes on the test points was evaluated. RESULTS: Logarithm model was apparently not adequate for the purpose and quadratic model and power model showed poor capacity for predicting the changes of the experimental data. Exponential model and cubic model, in contrast, well illustrated the trend of the changes in the data, therefore best met the demands. CONCLUSIONS: Exponential model best describes the trends of the changes of the experimental data and can procure continuous values of the pressure reduction in the cervical nucleus pulposus in association with varied cervical traction forces, thus offering useful information for relevant theoretical analysis.

Traction alopecia in children.

Traction alopecia is traumatic hair loss secondary to the application of tensile forces to scalp hair. This condition can be classified as marginal or nonmarginal. In either case, the induced trauma, often the result of cultural, social, and cosmetic practices, is unintentional. Initially, hair loss is reversible; however, permanent alopecia may result from chronic traction.

Effects of cervical traction and exercise therapy in cervical spondylosis.

A randomised clinical trial was conducted in the Department of Physical Medicine, Chittagong Medical College Hospital from July, 2001 to June, 2002. The objectives of the study were to find out the effects of cervical traction (CT) and exercise on the patients with chronic cervical spondylosis. A total of 199 patients with cervical spondylosis were included in the clinical trial. One hundred patients were treated with cervical traction plus exercise and 99 patients were treated with non-steroidal anti-inflammatory drug (NSAID). Posture correction advice was given to all patients. The patients were treated for 6 weeks. There was a marked improvement in both the groups after treatment (P<0.001). But there was nearly significant difference regarding improvement in treatment with CT plus exercise than with NSAID (P = 0.06). The results indicate that the improvement of the patients with chronic cervical spondylosis was more in CT plus exercise than analgesics. So, CT & neck muscle strengthening exercise may have some more beneficial effects than NSAIDs on chronic cervical spondylosis.

[Neuron-specific enolase (NSE) and S-100b protein in cerebrospinal fluid of patients with cervical spondylosis--the relations with MRI findings and the changes of NSE and S-100b protein levels through Glisson's traction].

We have previously reported that NSE and S-100b protein (S-100) could be used as reliable markers to evaluate the damage of the spinal cord in cervical spondylosis (CS) and ossification of posterior longitudinal ligament (OPLL). In the present study we made MRI in 21 patients with CS. There was a positive correlation between the NSE level in CSF and the degree of the spinal cord compression shown by MRI. In 10 cases of CS we examined these specific protein levels in CSF before and after the Glisson's traction therapy for one month. In seven of them the NSE levels decreased with the clinical improvements. On the other hand, 2 cases showed the rise of NSE levels after the traction. One of them became clinically worse during the therapy, while in another case the NSE levels changed within the normal range. The level of NSE in the other case was unchanged. In 57-year-old patient with CS myelopathy we examined the NSE levels chronologically. The NSE level changed in parallel with his clinical features. We suggest that NSE level in CSF may be a useful marker to estimate the change of the degree of the spinal cord damage in CS.

[Neurohistological characteristics of regeneration of the ends of the injured nerve under measured traction].

A resection of sciatic nerve in 25 dogs was performed out and the ends of cut nerve were connected by sutures with special apparatus for quantified traction of nerve stumps. 5 days after resection traction was stented at the rate of 0.25 mm twice a day. A histological analysis performed in 5, 12, 19, 26, 33 days after resection an 2-12 months after nerve suture has shown that stress strain effects on intercalation of nerve structures (Ilizarov's effect). Newly formed Schwann chains free of products of axonal and myelin disruption have got a perfect longitudinal orientation and that's why can be considered as an optimum substratum for axonal regeneration.

[Lengthening of residual digit by gradual traction and bone grafting (a report of 143 cases)].

Since 1985, a device for gradual traction was used for lengthening of 143 residual digits in 75 patients. The average lengthening was 2.2 cm. This method is simple, safe, and effective. The advantages of this method over the previously exercised tubed bone graft and other digital lengthening methods are that the digit reconstructed by the gradual traction-lengthening method has the normal cutaneous structure, good sensation function, and better contour. Multiple digits can be reconstructed simultaneously. Because the periosteum at the osteotomy site is kept intact, the long term results are consistent.

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.

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.

Elevated, straight-arm traction for supracondylar fractures of the humerus in children.

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.

Supracondylar fractures of the humerus in children: treatment by overhead skeletal traction.

A total of 120 children with severely displaced supracondylar fractures of the humerus in the absence of neurovascular deficit were treated by overhead skeletal traction. The results were assessed according to Flynn's criteria. After a mean follow-up period of 3.5 years, 68 children (56%) had an excellent result, 40 (34%) had a good result, 4 (3.5%) had a fair result, and 8 (6.5%) had a poor result. Cubitus varus was present in only 4 cases, which compares favorably with the results of operative treatment. The indications for overhead traction and the satisfactory results of this method are discussed.

Esthetic restoration with orthodontic traction and single-tooth implant: case report.

This case report describes the use of orthodontic traction to recover soft tissue lost around a maxillary right central incisor with major external root resorption associated with severe gingival recession. Traction of the residual root for 1 month produced a gingival appearance in harmony with the adjacent teeth. After the placement of an implant, a correct emergence profile was obtained, giving an optimal esthetic outcome. After a 3-year follow-up, complete regeneration of soft tissue persisted around the implant-supported crown.

[Axial and derotational traction before surgery for slipped femoral capital epiphysis].

18 cases of slipped femoral capital epiphysis were prepared for surgery by axial and derotational traction lasting 1 to 5 (av. 2,9) weeks. In all cases significant pain relief was achieved, partially the range of passive motion in the hip was improved. No reduction of slipped epiphysis was recorded. Best results occurred in medium and severe (> 60 degrees) cases. The traction before surgery for slipped femoral epiphysis is considered to improve range of motion, bring good pain relief, but not reduce the slipped epiphysis.

[Is treatment of C.D.H. by progressive reduction by traction still advisable? (author's transl)].

The authors analyse the results that they have obtained in the treatment of C.D.H. either by conservative or surgical methods. The prevention of osteochondritis remains the main worry. However traction leads to long-lasting immobilization and sometimes it is not sufficient. The authors think that osteochondritis may be related to hyper-pressure on the femoral head or to lesions of the vascular pedicle and that in some cases shortening of the femur or tenotomies may allow a decrease of the plaster cast period. The indications on capculotomy, rotation osteotomy, salter osteotomy are discussed. It is concluded that the periods of traction and plaster cast immobilization should be lessened as much as possible.

[Hip joint development after treatment the developmental dislocation with overhead traction].

Despite the fact that ultrasound of children's hips is widely used for screening, late diagnosed cases of developmental dislocation of the hip are still a common problem in the orthopaedic practice. The aim of the study is to review final clinical and radiological outcomes of treatment of DDH with overhead traction and closed reduction after skeletal growth. Clinical records and radiograms of 107 hips (81 children) were retrospectively reviewed. All of them were treated according to the same program: overhead traction (about 2 weeks), followed by closed reduction, modified Lorenz cast (2 months) and finally cast in Lange position (3 months). Average age of children was 14.2 months at the beginning of treatment and 20.7 years at last visit. Good and very good results were found in 80% of cases according to final radiological assessment of Severin and in 91% according functional classification of Harris. Avascular necrosis of femoral head according to Bucholz-Ogden classification system was identified in one third of patients. Functional results are better than radiological, but deteriorated with time especially in hips with residual dysplasia and AVN due to development of early, secondary degenerative changes.

[Indication and application of the cervical traction headgear].

Two types of cervical headgear were presented, the cervical traction with caudal tip and with cranial tip of the long outer bow. The results of an actual long-term follow-up study show long-term stability after distalization with both appliances. The indication and application of the cervical traction are described as a two-term movement. Type I, the cervical headgear with long outer bow tipped 10 to 15 degrees caudal to the inner bow allows to move the crown of the molar distally and to upright mesially tipped molars; the classic indication is the dentoalveolar class II division 1. Type II with long outer bow and tip of 10 to 15 degrees cranial is indicated to upright the roots distally in cases of dentoalveolar and/or skeletal class II with deep overbite. As a concluding remark the recommendation is made that the indications for extraction therapy are understood and that cervical headgears are not seen as a substitute for extractions.

Use of traction in cervical spine fractures during interhospital transfer by aircraft.

Despite significant improvement in the organization and function of the nation's emergency medical services and the increasing sophistication of initial providers of critical care, there has apparently been no reduction in the incidence of neurological deficits suffered by patients with unstable cervical spine injuries during management prior to intervention by the spine surgeon. In analyzing the techniques used to stabilize patients with suspected unstable cervical spine injuries during this phase, we conclude that present standard techniques are either insufficient or potentially destabilizing. We have developed a system that will permit the use of cervical traction, applied with a halter or the standard Gardner-Wells tongs, during the prehospital phase of management of patients with cervical spine injuries. Based on our experience with the system, we recommend that patients with such injuries be stabilized with skeletal traction when transferred between hospitals by air ambulance. Logic permits consideration of the concept even earlier in the prehospital phase of management and in ground ambulances.
