Articular cartilage evaluation in osteoarthritis of the hip with MR imaging under continuous leg traction.

We conducted MR evaluations of acetabular and femoral cartilages in 27 hips of patients with osteoarthritis and 10 hips of normal volunteers by a fat-suppressed three-dimensional (3D) pulse sequence using a continuous leg traction method, and correlated the results with radiographic assessment. Normal condition of the acetabular and femoral cartilages was clearly demonstrated in the normal volunteers. Grading of abnormalities was possible for each cartilage in the patients with osteoarthritis. In early osteoarthritis graded by radiography, a high prevalence of abnormalities was detected in the acetabular cartilage as compared with the femoral cartilage. Despite the structural difficulty in evaluation of the hip joint cartilage, our MR imaging technique can provide information concerning a wide spectrum of cartilage abnormalities even in the identical radiographic stage, which will lead to improvement in the evaluation of disease progression and in surgical planning.

Comparison of Jones jig molar distalization appliance with extraoral traction.

In this study, 20 patients were evaluated. Ten were treated with intraoral distalization followed by fixed appliance therapy, and 10 were treated with extra oral traction followed by fixed appliance therapy. Molar relationship correction was achieved in 2.5 months with intraoral distalization and in 10.7 months with extraoral distalization. A significant anterior movement of the anchorage unit (P <.001) was observed with the intraoral distalization and a significant distal drift of premolars was observed in the headgear group (P <.05). Palatal plane was found to tip downward significantly in the headgear group (P <.05). Total outcome of the 2 methods were discussed evaluating the advantages and disadvantages of the 2 distalization methods.

Tunnel traction of infraosseous impacted maxillary canines. A three-year periodontal follow-up.

A surgical orthodontic procedure was used to treat deep infraosseous impacted canines (test teeth) associated with the persistence of the deciduous tooth in 15 patients who had the contralateral canine normally erupted (control teeth). The periodontal outcome was evaluated at the end of the orthodontic treatment and 3 years later. After extraction of the deciduous canine, a mucoperiosteal flap was raised on the buccal (seven cases) or palatal (eight cases) aspect, to expose the cusp of the impacted tooth. The empty socket of the deciduous tooth was extended to reach the impacted cusp and to form an osseous tunnel. A chain was passed through the tunnel and fixed to a bonded device on the impacted cusp. The flap was sutured back into its original position. The chain was used for traction to the impacted canine toward the center of the alveolar ridge. No attachment loss and no recession were observed at the end of the active therapy or 3 years later. No significant differences in keratinized tissue width were observed between test and control teeth at the follow-up examination.

Zygomatico-maxillary fractures. Late results after traction-hook reduction.

A simple, closed method for zygomatico-maxillary fracture treatment is described i.e. replacement by the use of a traction bone-hook. After X-ray and clinical examination had excluded undisplaced fractures, blow out fractures and comminuted fractures, the postreduction stability was assessed peroperatively and again one week after. Sophisticated preoperative fracture-classifications predicting postoperative stability appeared redundant. In the present study, this procedure could be performed in 55.4% of the total fractures which needed to be reduced. At re-evaluation, two to eight years later, the results remained satisfactory. The method appeared, in addition to its simplicity, to require less complicated postoperative care and, therefore, a short hospitalization.

The use of extra-oral traction with removable appliances.

Extra-oral traction has two main applications in orthodontic treatment. It may be used to prevent forward movement of anchor teeth and also to provide a force for distalisation of molars, and/or buccal segments. If correctly applied, EOT can help to ease problems in a difficult treatment and make possible an otherwise impossible treatment plan.

Treatment effects of Fränkel, activator and extraoral traction appliances.

The effects of the Fränkel appliance on the treatment of Class II, Division 1 malocclusion were compared with the activator, high-pull headgear, cervical traction and a control group. A sample of 16 Fränkel cases treated in the mixed dentition was tested in four craniofacial areas, with findings as follows: a. Maxillae, no significant horizontal effect b. Mandibular length, significantly increased c. Lower face height, widely variable effects. d. Less upper molar eruption and more lower molar eruption. Although the findings of this study should be interpreted as tentative, they do show the Fränkel appliance to have some different mean effects on the craniofacial complex. Variability is a most important aspect of the findings of this study. Future studies must deal not only with mean changes, but with the Fränkel appliance's variable effects on differential individuals. Optimal application of this appliance requires judgment in case selection and careful analysis of progress, using adequate follow-up records and a firm knowledge of normal growth and development of the craniofacial complex.

Comparative long term post-treatment changes in hyperdivergent Class II Division 1 patients with early cervical traction treatment.

This was a retrospective study of 45 Class II Division I hyperdivergent patients treated in the mixed dentition with cervical traction and an incisor biteplane. The interjaw or "B" angle (mandibular plane to palatal plane angle) was used to determine hyperdivergency. The treated sample was subdivided into 2 groups reflecting whether the mandibular or palatal plane contributed the greatest amount to the more than 1 standard deviation of the "B" angle from the mean value of the "B" angle present in the 89 untreated Class I controls. Complete records including lateral cephalometric head films were acquired at the start of treatment and 18 to 91 months after discontinuing all retention. Null hypotheses were designed to determine if any significant changes in the "B" angle, mandibular plane angle, or palatal plane angle occurred in the control group or the treated group. Thirty-two angular, linear, and proportional data were accumulated to determine the presence or absence of significant differences. The only significant angular differences found were in the group in which the palatal plane inclination was increased relative to Frankfort Horizontal. In this group, the palatal plane became more nearly parallel to Frankfort Horizontal than in the control group, and showed an increase instead of a decrease in the Y-axis. Proportional and linear data indicated the palatal plane change was a lack of descent of Posterior Nasal Spine while the descent of Anterior Nasal Spine was equal to that of the control group. The increase in the Y-axis was not the result of bite opening, but a lack of mandibular horizontal development as indicated by less of an increase in the Facial Angle. Of the 45 patients, only 4 (9%) required 2 phases of treatment and 1 of those required extraction. Thirty patients (67%) completed treatment with alignment and retraction of the maxillary anterior segment and 11 (24%) had additional alignment of the mandibular anterior segment.

Prehospital midthigh trauma and traction splint use: recommendations for treatment protocols.

The present study was completed to establish an epidemiologic database defining the prehospital occurrence of midthigh trauma/suspected femoral shaft fractures, and the use of/need for traction splints (TS) in hope of developing recommendations for further treatment protocols. On review of 4,513 paramedic run reports for the 12-month period from January 1999 through December 1999, from a low-volume urban emergency medical services (EMS) system, 16 persons (0.35% total patients) presented with midthigh injuries. Data collected included patient chief complaint/injury, mechanism of injury, clinical findings, splint application, additional interventions, iatrogenic complications, patient age, and ambulance field time. Paramedics noted injuries suspicious for femoral shaft fractures in 5 patients (31.25% study patients, 0.11% total patients). TSs were applied successfully only twice (12.50% study patients, 0.04% total patients). Fourteen patients (87.50% study patients) were managed with long backboard immobilization, rigid splinting, and/or patient transportation in a position of comfort. No sequelae as a result of such care occurred. No inappropriate use, point estimate (PE) [(0)/(16) (0.00% to 20.60%)] or unmet need, PE [(0)/(4), 497) (0.00% to 0.08%)] of care was noted. The data presented in this study suggest that given similar EMS system characteristics, prehospital midthigh injuries/suspected femoral shaft fractures occur on an extremely rare basis, and treatment with long backboard immobilization, rigid splinting, and/or patient transportation in a position of comfort may constitute an acceptable course of care. Including TSs as essential ambulance equipment may be unnecessary.

How to avoid and manage nerve injuries associated with aortic surgery: ischemic neuropathy, traction injuries, and sexual derangements.

Both open and endovascular surgery of the infrarenal aorta are attended by risks of neurologic complications. Injury to the periaortic autonomic plexi frequently results in ejaculatory and erectile dysfunction. Traction injuries to lumbosacral nerve roots can cause peripheral nerve injury, most commonly exhibited as a femoral nerve deficit. The least common but most feared neurologic complication that can occur with infrarenal aortic surgery is ischemic injury to the spinal cord, or conus medullaris. The risk of this complication is increased with emergent or complicated aortic reconstructions. The importance of internal iliac artery perfusion to the development of ischemic cord and nerve root injury has been recognized. Although some neurologic complications may be avoidable by technical modifications, there is a small and probably irreducible neurologic risk to aortic surgery that should be considered when weighing options for treatment of aortic pathology.

[Ventral intercorporeal traction spondylodesis of the lumbar spine].

At 35.7% the average rate of pseudarthrosis following ventral spondylodesis of a segment of the lumbar spine is very high. The inadequate degree of primary stability in the segment to be ankylosed is seen as the fundamental reason for this. In the present paper an implant made of a nickel-titanium alloy ("Memory Alloy") is described, which is inserted intercorporeally and immobilizes the moving segment by traction. Experiments in sheep have confirmed that the anchorages of the implant are stable; it was also established that bony fusion occurred both around the implant as well as through it. Observations thus far in 10 patients treated by this method have shown that the implant remains stably anchored, and in some cases clear signs of bone bridge formation were demonstrable on radiographs after only a short time. If the primary stability provided by the Memory implant continues to be thus confirmed, postoperative hospitalization will in future be limited to a few days.

The school-age traction patient: toward better behavior patterns.

Being confined to bed in traction is a decidedly frustrating experience for the pediatric patient. Following the initial adjustment of the trauma of the accident that precipitated the present limited environment, the patient assumes a behavior pattern that he thinks will enable him to cope with the predicament. One of the following three roles is usually exhibited: 1) reasonable independence, 2) problem dependency, 3) manipulation. The awareness and understanding of these patterns and their variations with a practical response from the hospital staff will help the patient to project his natural personality and to develop an acceptable level of self-sufficiency even during this time of physical restriction.

Whiplash-associated chronic headache treated with home cervical traction.

The subject of this case report was a 56-year-old woman who sustained a whiplash-associated disorder as a result of a motor vehicle accident. Within a few hours after the accident, she developed a headache, which became chronic, creating disability and hindering the quality of her life. In the following year, a variety of diagnostic tests, medications, and physical therapy were unsuccessful in determining the cause of her complaints or in relieving them. After this year, she expressed anger, frustration, and a reluctance to undergo additional physical therapy. By listening to her explain how she coped with her problem and observing that she lacked the ability to reduce her cervical lordosis, the therapist developed and implemented a home program of supine cervical traction and exercise. After 30 days of treatment, she was able to reduce and control her headache. This treatment and the approach used to develop the treatment may benefit other patients who have whiplash-associated chronic headache.

Back pain and sciatica: controlled trials of manipulation, traction, sclerosant and epidural injections.

Four treatment regimens for patients with specified combinations of low back pain and sciatica were evaluated. The largest group studied had low back pain with limited straight-leg raising (SLR) and in them the beneficial effect of manipulation in hastening pain relief was highly significant. In similar patients without limitation of SLR, the effect was of borderline significance. In all the other groups, treated patients also recovered more quickly than their controls. Traction, for patients with low back pain and sciatica, and epidural injections when a root palsy was present also produced some significant pain relief. The effect of sclerosants for back pain was less clear.

The impact of prostanoids on pulmonary gas exchange during abdominal surgery with mesenteric traction.

We investigated the effect of intravenous (iv) ibuprofen on prostanoid release and on pulmonary gas exchange after abdominal mesenteric traction (MT) during either abdominal aortic surgery or pancreas resection. In a prospective, randomized, double-blind study, 400 mg ibuprofen (pancreas n = 13, aorta n = 13) or a placebo (pancreas n = 13, aorta n = 13) was administered iv before skin incision. MT was applied uniformly. The prostanoid plasma concentrations, venous admixture (Q(va)/Q(t)), and PaO2/FIO2 ratio were determined at baseline (before MT) and 5, 15, 45, and 90 min after MT. Patients who underwent aortic surgery were older and exhibited a lower preoperative PaO2 than those who underwent pancreas resection. Placebo-treated patients revealed a 30-fold peak increase in 6-keto-prostaglandin F1alpha (stable metabolite of prostacyclin) levels after intentional MT during aortic as well as pancreatic operations. This response was accompanied by an increase in Q(va)/Q(t) (ibuprofen: pancreas 7% +/- 1%, aorta 14% +/- 2%; placebo: pancreas 16% +/- 3%, aorta 26% +/- 3%/15 min after MT [mean +/- SEM, P < 0.05, placebo vs ibuprofen]), which resulted in decreased PaO2/ FIO2 ratio only in the aortic surgery patients (ibuprofen: 310 +/- 19; placebo: 237 +/- 24 15 min after MT, [mean +/- SEM, P < 0.05]). The authors conclude that ibuprofen-pretreated patients demonstrated almost constant prostanoid levels without changes in pulmonary gas exchange after MT.

Cranial morphometry related to placement of tongs in the temporoparietal area for cervical traction.

The optimal placement of cervical traction tong pins to avoid cranial penetration or tong pull-off is not well established. Cranial thickness and transverse diameter in the temporoparietal area we believe to be important variables: The former was measured on 10 embalmed cadaveric specimens, the latter on 20 cleaned skeletal specimens. For each specimen, measurements were obtained at 29 points arranged within a 5 x 9-cm rectangular region above the external auditory canal. Within this region, no significant thickness variations occurred, except for one point each at the extreme posterocephalad and posterocaudad corners. Transverse diameters were constant in the area just above the pinna and gradually decreased in the anterior, posterior, and cephalad directions. No outward-flaring temporal ridge was found. We recommend pin placement just above the pinna. Anteroposterior position should probably be determined by the amount, if any, of flexion or extension desired.
