Traction*

Most patients with hangman's fracture frequently responded to consertvative therapy consisted of skeletal traction and halo vest, and surgery to stabilize or reduce further injury is seldom necessary. But occasionally operative stabilization may be necessary and can be achiveed satisfactorilly through anterior or posterior approach. Anterior interbody fusion at the G2-3 interspace has advantages of immediate bony stabilization with preservation of rotatory motion compared with posterior approach.

A patient who had an atlanto-axial dislocation due to an os odontoideum is presented. She was operated on successfully with preliminary realignment of the dislocation by skeletal traction and subsequent posterior cervical fusion with wiring and iliac bone.

STUDY DESIGN: An experimental biomechanical study. PURPOSE: This study aims to investigate the behavior of a lamina injury in lumbar burst fractures during reduction maneuvers. OVERVIEW OF LITERATURE: Lumbar burst fractures are frequently accompanied by a lamina fracture. Many researchers concluded that any reduction maneuver will close the fractured lamina edges and possibly crush the entrapped neural elements. This conclusion did not rely on solid biomechanical trials and was based primarily on clinical experience. METHODS: Eighteen fresh-frozen lamb spines were randomly divided into three groups. Using the preinjury and the dropped-mass technique, a burst fracture model was developed. A central laminectomy of 5 mm of the L3 lumbar spine was created to mimic a complete type of lamina fracture. To measure the movement of the fractured laminar edges, two holes were drilled on both sides of the upper and lower regions of the lamina to allow for optic marker placement. A single specific spine movement was applied to each group: traction, flexion, and extension. Gap changes were measured by camera extensometers. RESULTS: After traction, the average values of the upper and lower aspects of the lamina interval showed narrowing of 1.65±0.82 mm and 1.97±1.14 mm, respectively. No statistical significance was detected between the two aspects. The upper and lower regions of the lamina gap behaved differently during extension. At 10°, 20°, and 30°, the upper part of the lamina interval was widened by an average of 0.016±0.024, 0.29±0.32, and 1.73±1.45 mm, respectively, whereas the lower part was narrowed by an average of 0.023±0.012, 0.47±0.038, and 1.94±1.46 mm, respectively. CONCLUSIONS: Neural element crushing may take place, particularly at the lower aspect of the fractured lamina gap during extension and throughout the whole lamina gap during traction. The lamina gap widens during flexion. Reduction maneuvers should be attempted after exploring the fractured lamina to prevent further neurological compromise.

The results of diabetic vitrectomy on eyes with severe proliferative fibrovascular membranes are often disappointing, because of difficulties in removing the membranes. But we sometimes observe the regression of the proliferative fibrovascular membranes when the antero-posterior tractional force become released. Hence we compared the surgical prognosis of proliferative diabetic retmopathy according to the severity of proliferation and whether removal of antero-posterior vitreoretinal traction was complete or not. The results showed that the anatomic success rate and final visual acuities(VA) were significantly better in less-severe proliferation group(LSPG) than in severe prolif era tion group(SPG). In SPG, the anatomic success rate and VA tended to be better when we were able to remove the antero-posterior vitreoretinal adhesion completely whether the removal of preretinal membranes was complete or not. When complete removal of the diabetic fibrovascular membrane is difficult due to severe proliferation and broad adhesion, complete removal of anter-posterior traction only could be an alternative in diabetic vitrectomy.

Recently we experienced 10 cases of posterior urethral injury associated with pelvic fracture. Of these patients 5 underwent primary realignment with perineal traction on the prostate (Selikowitz method), and the other 5 underwent immediate cystostomy and delayed urethroplasty (Johanson method). Comparison of the post-operative complications didn`t appear to show significant differences in the 2 groups, although the numbers were small. But patients who performed immediate cystostomy and delayed urethroplasty showed some disadvantages of the long period of treatment, high charges, often multiple hard procedures and the long time of operation. Therefore in the initial management of posterior urethral injury, we think it better to take primary realignment in Korean socioeconomic circumstances, if the patient is not in the high risk.

This research aimed to improve the advantages of the continuous traction on bed and traditional binding with bamboo slabs for bone fracture. The authors also research on using PouliquÌnstyle frames in treating for patients with severe supracondylar fracture who were not able to bind normally, especially when lack of equipment. 52 patients aged from 7-15 years old with closed supracondylar fracture were involved in the study. Each of them was treated in two phases. First, after minimum reduction, the patient was passed a K-needle through olecranon and given continuous traction with 2-3 kg for 2 weeks on a PouliquÌnstyle frame made from crame slabs. Then, in the second phase, the patient was bound by traditional bamboo slabs that allow the elbow movement, before and after reduction once a week during treatment process. the results showed that this method can treat successfully for some cases with severe supracondylar fracture who failed on reduction and have surgical indication. 77.08% of patients were excellent and good, 16.66% were moderate and 6.25% were bad.

Between 1984 and 1995, sixty-one patients were treated for facet interlocking of the cervical spine. The most common level of dislocation was C6/7; unilateral facet locking was observed in 27 patients, and bilateral locking in 34. Immediate traction with increasing weight reduced the dislocation in 51 patients, but ten required surgery, and of the 51 patients whose dislocations were successfully reduced with traction, 36 underwent surgery due to spinal instability.In all 46 patients who were operated on, spinal stability was achieved without major complications. On discharge, neurological improvement was observed in 18 patients. These findings suggest that even in neurologically compromised patients, prompt reduction and internal stabilization can facilitate recovery.

PURPOSE: To traditional treatment of pediatric femoral shaft fracture has been a traction and spica cast application. But flexible intramedullary nail fixation has been introduced as an alternative to other treatment modalities. With this in mind, we analyzed the clinical and radiologic results of flexible intramedullary nail fixation of pediatric femoral shaft fractures. MATERIALS AND METHODS: We analyzed 12 patients (13 cases) who were treated with flexible intramedullary nail and followed up for at least 6 months at the department of Orthopedic Surgery, Inje University Ilsan Paik Hospital since May, 2002. RESULTS: In all 12 patients (13 cases) involving 1 case with reoperation because of reduction failure, average duration of bone union was 12.6 weeks. There were no considerable complications except mild post-op knee pain and limitation of motion. CONCLUSION: In spite of relatively short term study, a flexible intramedullary nail fixation seems to be a useful method without serious complications on pediatric femoral shaft fracture. However, in big or older pediatric patients, interlocking intramedullary nail fixation may be a better choice rather than a flexible nail fixation because of it's insufficient stability.
