Experimental determination of the center of resistance of the upper first molar in a macerated, dry human skull submitted to horizontal headgear traction.

Laser speckle interferometry, recently developed for noninvasive measurement of small displacements (microns), was used to study the movement of maxillary molars submitted to extraoral traction. Using an antenna-headgear at different horizontal levels, loadings of 700 gm were applied perpendicular to the long axes of these teeth. Bodily movement was observed when the traction line passed slightly occlusal to the trifurcation of the roots. Therefore, the center of resistance of the upper molar was experimentally localized at this level. Laser speckle interferometry proved to be a promising technique for dental research.

Very long gap esophageal atresia successfully treated by esophageal lengthening using external traction sutures.

Esophageal atresia with a 6-cm gap or longer and a very short distal segment represents the extreme of this disorder's spectrum, the treatment of which can be challenging. Very often, several surgical procedures have to be carried out to maintain the patient's own esophagus. The authors report on a child born with isolated esophageal atresia without fistula and a very long gap (8.5 vertebral spaces in length). Delayed anastomosis was accomplished using a combination of various procedures that included a waiting period allowing for spontaneous esophageal growth, mobilization of the distal segment, and esophageal lengthening by external traction sutures. The aim of this report is to define the role of the traction method in the repair of this kind of atresia.

Old principles revisited--traction splinting for closed proximal phalangeal fractures.

Proximal phalangeal fractures are commonly caused by a blunt injury to the dorsum of the hand. This typically results in a closed transverse fracture with volar angulation, which is an inherently unstable fracture pattern. K-wiring and internal fixation have the disadvantage of damage to the soft tissue envelope, risk of infection and wire loosening. We describe 15 patients treated with an alternative method of skin traction and splintage in our regional trauma centre. Fractures were reduced under X-ray and reduction was maintained using a combination of a malleable metal splint and tape to provide skin traction. Fourteen patients had an excellent objective and subjective outcome. The advantage of our technique is preservation of the soft tissue envelope and it should be considered an alternative to other treatment options as it is simple, quick, inexpensive and non-invasive.

Olecranon screw traction for displaced supracondylar fractures of the humerus in children.

Twenty six children with severely displaced supracondylar fractures were treated with closed reduction and vertical osseous traction with an olecranon screw. Four children required a second operation in the form of open reduction and K-wire fixation for failure to achieve a satisfactory reduction. After a mean follow up of 48 weeks, 20 children (91 per cent) had an excellent result with no significant loss of movement. Two children (9 per cent) had minimal cubitus varus (av. 8 degrees) which did not require a corrective osteotomy. All four children who had a second operation had an excellent result. The average hospitalisation time was 19 days. The method of olecranon screw traction is technically easy to perform and carries few risks of complications.

Simple cervical spine traction using a halo vest apparatus: technical note.

BACKGROUND: A halo vest apparatus, commonly used for external immobilization and protection of the cervical spine, offers several advantages. We present here a simple, accurate, easy, and safe cervical traction technique using a halo vest apparatus. METHODS: The distinguishing feature of our technique is that, after application of a halo vest apparatus, the halo crown is distracted gradually and stepwise by turning the bilateral screw bolts that hold the halo crown over a period of one to several weeks. After each of these steps, care must be taken to check neurologic, radiologic, and skin conditions, as well as cranial pin tightening. CONCLUSIONS: This distance control technique can provide a strong and accurate traction force by simply turning the bolts without the risk of overdistraction or the need for bed rest, and can be used in conjunction with radiologic examination and transportation of patients, even those unable to walk. The Sugita head fixation system constitutes a safe and easy way to facilitate surgical management after correction of cervical dislocation.

En Bloc removal of soft tumors within the brain parenchyma using spoon retractors: traction-dissection method. Technical note.

BACKGROUND: En bloc removal of soft tumors within the brain parenchyma has rarely been performed. We describe a safe technique for en bloc removal of the tumors using a spoon retractor, which enables retraction while holding the soft mass upward. METHODS: Dissection of a tumor mass is performed under traction of the surrounding brain tissue by retracting the mass using a spoon retractor. A dissection plane is first established in a relatively safe area, not opposite the critical area, after a corticotomy. The dissection plane is then extended toward the critical side. After circumferential dissection of the tumor mass, the dissection is continued spirally into deeper regions by retracting and holding the mass upward using a spoon retractor. In this way, the tumor is removed en bloc. CONCLUSIONS: The traction-dissection method using spoon retractors is useful in performing en bloc removal of soft tumors within the brain parenchyma less invasively and provides an appropriate operating field even at depth, reducing intraoperative bleeding, and in vascular rich tumors, possibly preventing tumor seeding in cases of malignant tumors.

Pins and Rubbers Traction System.

The Pins and Rubbers Traction System (PRTS) is a mobile frame created with wires to support elastic traction, which produces a ligamentotaxis effect in the same direction and of the same intensity whatever the position of the joint. This technique has been used in 11 cases of complex PIP joint fractures with eight excellent results. The advantages are simplicity, adaptability, the possibility of immediate mobilization, reasonable cost and relatively small bulk.

The proximal interphalangeal joint swing traction splint.

Conventional PIP joint flexion splints exhibit several shortcomings regarding kinematic and kinetic behavior. A new PIP joint swing traction splint (STS) has been developed to overcome these shortcomings while maintaining the advantage of the ease of use of conventional simple rubber band traction devices. This article defines the advantages of the STS system in terms of physics and also describes the fabrication technique involved.

Severe lower lip disfigurement resulting from war injuries. Management by local tissue traction.

A new technique is presented for severe lower lip disfigurement resulting from war injury. The procedure consists of a Kirschner wire used as the means of traction on the remaining soft tissue of the lower lip, using the upper teeth or pyriform aperture bone as remote fixed points for tissue traction. The technique which is simple, short, and effective provides an acceptable appearance, texture, and skin sensation. It proved to have several advantages over other more commonly employed methods.

Forward traction of the maxilla with cleft lip and palate in mixed and permanent dentitions.

The effect of forward maxillary protraction with the Delaire type facial mask was studied in fourteen patients with cleft lip and palate. Traction on the maxilla was initiated between 9 and 15 years of age and the duration ranged from 5 go 36 months, averaging 19 months. The average magnitude of the traction forces was 300-400 gm. Parallel or downward direction of the forces in relation to the occlusal plane were used from the first molars and the precanine loops of the arch wire. Forward movement of the maxilla was observed in five 9-11-year-old patients. No movement was observed in nine patients over 11-years of age. In spite of the poor results of forward movement of the maxilla in the older patients, the facial mask therapy proved to be successful in correction of the anterior crossbite, spacing of the dental arch, and as an anchor in widening the upper dental arch.

Edgewise therapy with cervical and intermaxillary traction--influence on the position of the bony chin.

Comparison of treatment and control samples was intended to reveal those factors which, during Class II correction using Tweed Edgewise technique in conjunction with intermaxillary traction and low cervical traction to upper molars, may lead to undesirable posterior rotation of the mandible. Both samples exhibited similar condyle growth rates. Increased variability of the parameters tested was found within the treatment group. No significant difference was found in the vertical movement of the upper molars, while anterior movement of the upper molars was significantly inhibited in the treatment sample. The treatment sample displayed increased vertical and decreased anterior movement of pogonion, accompanied by posterior rotation of the mandible. Close and similar correlations were found in both samples between the anterior movements of the upper molars and pogonion, between the angles of upper molar and pogonion displacement in relation to Frankfort Horizontal, and between both of the upper molar parameters and changes of mandibular rotation. In the treated sample it was inhibition of anterior movement of the upper first molars, not enhancement of vertical movement that appeared to cause posteroinferior rotation of the mandible and displacement of pogonion through a geometric interdependence. The direction of upper molar movement and condyle growth rate both exert important influences on changes in position of the growing mandible and thus on the nature of profile changes in Class II correction.

Mixed dentition treatment with cervical traction and lower lingual arch.

The quantitative changes which occurred as the result of this specific regimen of treatment in a sample of Class II malocclusions in the early mixed dentition were compared with like changes in a closely matched sample of untreated Class II malocclusions. Selected parameters were also compared with a comparable group of Class II malocclusions treated with only a Kloehn cervical appliance. Treatment as described does tend to slightly increase the vertical eruption of the upper molar. No maxillary orthopedic effects were noted in the horizontal plane. There was significant inhibition of the forward displacement of the upper molar. Cervical traction without anterior bands resulted in actual distal movement of the upper molar, not just an inhibition of its forward growth. The treatment significantly inhibited the forward growth of the upper incisors and point A. Cervical traction alone had less effect on overjet and the S-N-A angle. A lingual arch is effective in maintaining lower leeway space while still allowing horizontal and vertical growth changes in the positions of molars and incisors. Rotation of the mandible was downward and backward. Overall face height was increased.

Changes in circumferential neck measurements during movements of the head in children and their relevance to extraoral traction.

One of the causes of facebow injuries to patients wearing extraoral traction has been the catapult effect of the simple elasticized materials used in the past. A variety of safety or self-releasing modular systems to counteract this catapult effect are currently available. However, the strap extension provided by these modules varies considerably. To reduce the catapult effect to a minimum, it is desirable to fit a system with the minimal travel that will accommodate any changes in distance between the facebow and the back of the head or neck. To ascertain the minimal travel required for the straps, circumferential neck measurements were carried out on 105 children aged between 9 and 14 years. The change in circumference was recorded for 3 different head positions. The mean distance change between the back of the neck and the end of the facebow was 25 mm per side, with a range of 4 mm to 50 mm. This study suggests that on average, modules with a 25-mm extension will be required for cervical traction.

Internal jugular vein thrombosis after cervical traction.

A clinically and roentgenographically typical case of internal jugular vein thrombosis is presented in a patient having undergone repeated sessions of Glisson traction for neck and backache. In this mode of therapy, axial traction is applied to the neck by attaching a weight, via a pulley, to a construction of straps encompassing the head. This particular trauma to the neck has not previously been described to be associated with spontaneous internal jugular vein thrombosis.

The role of magnetic resonance imaging in the management of traction injuries to the adult brachial plexus.

Magnetic resonance imaging (MRI) of the cervical spine and brachial plexus was performed on 26 consecutive patients presenting with traction injuries of the brachial plexus during 1996 and 1997. These included T1 and T2 weighted coronal, sagittal and axial images of the cervical spine and coronal images of the brachial plexus. The results were compared with surgical findings, intraoperative neurophysiology, and subsequent clinical progress. Operations for exploration and repair have been performed in 23 and 26 patients scanned. Evidence of root avulsion was seen in 11 patients in the form of displacement or oedema of the spinal cord, haemorrhage or scarring within the spinal canal, absence of roots in the intervertebral foramena, and meningoceles. Characteristic abnormalities were evident in the MR scans of all cases where exploration confirmed some root avulsions. There were no false positives. MRI underestimated the number of individual roots avulsed; sensitivity was 81%. Post-ganglionic lesions were seen as swelling on T1 images associated with increasing signal on T2 images. It was usually possible to define the level of the injury within the plexus. This study suggests that MR imaging, performed early after traction injury to the brachial plexus, provides useful additional information towards establishing the level of the lesion. It also provides information about injury to the plexus outside the spinal canal.

Imaging of adult brachial plexus traction injuries.

Closed, high-energy transfer traction injuries of the adult brachial plexus lead to rupture or avulsion of the spinal nerves. Accurate preoperative diagnosis is crucial for surgical planning and reconstruction. Myelography, computerised tomographic myelography and magnetic resonance imaging are the main radiological methods for preoperative diagnosis of the lesion. This article reviews the current status of imaging of traction injuries of the adult brachial plexus.

[The magnetic resonance tomographic optimization of hip joint cartilage visualization by the selection of a T1-volume gradient-echo sequence and the use of hip-joint traction].

PURPOSE: The purpose of this study was to examine the accuracy of MR imaging of the healthy and the arthrotically altered articular hip cartilage with in vivo and in vitro separation of femoral head cartilage and acetabular cartilage. MATERIAL AND METHODS: Images of three animal cadaver hips, 8 dissected patient femoral heads and 18 hip joints of human corpses, all either with arthrosis stage I-III or artificial cartilage defects, were compared with their corresponding anatomic sections. Additional histomorphologic examinations of the arthrotic cartilages were conducted, and MR-Imaging of 20 healthy and 21 arthrotic patient hips was performed using a specific traction method. RESULTS: Using a T1-weighted 3-dimensional gradient-echo sequence and a traction of the hip joint, it was possible due to the low-signal imaging of the joint space to separate in vivo the high-signal femoral head cartilage from the high-signal acetabular cartilage. In horizontal position of the phase-encoding parameter, minimisation of the chemical-shift artifact, mainly in the ventro-lateral areas, was accomplished. MRI measurements of the articular cartilage widths showed significant correlations (p < 0.001) with the corresponding anatomic sections. At the same time the T1 3-dimensional gradient-echo sequence of the lateral femoral head with r = 0.94 showed the lowest deviations of the measurements. It was possible with MR imaging to distinguish four cartilage qualities. CONCLUSIONS: Using these MR-examinations, an improved imaging of early stage arthrotic cartilage defects is possible, and the status of the arthrotic hip cartilage with regard to intertrochanteric osteotomy can also be assessed.
