OBJECTIVE: Morphometric data for the lumbar posterior longitudinal ligament (PLL) was investigated to identify whether there is a difference in the morphometry of the PLL of the lumbar spine at each level with respect to the pattern of intervertebral disc displacement.METHODS: In 14 formalin-fixed adult cadavers (12 males and 2 females), from L1 to L5, the authors measured the width and height of the PLL and compared them with other landmarks such as the disc and the pedicle.RESULTS: Horizontally, at the upper margin of the disc, the central portion of the superficial PLL covered 17.8–36.9% of the disc width and the fan-like portion of the PLL covered 63.9–76.7% of the disc width. At the level of the median portion of the disc, the PLL covered 69.1–74.5% of the disc width. Vertically, at the level of the medial margin of the pedicle, the fan-like portion of the PLL covered 23.5–29.9% of the disc height. In general, a significant difference in length was not found in the right-left and male-female comparisons.CONCLUSION: This study presents the morphometric data on the pattern of intervertebral disc displacement and helps to improve the knowledge of the surgical anatomy of the lumbar PLL.

Development of new surgical devices and approaches for management of injuries to the cervical spine has offered various methods of treatment available. Making it is not easy in choosing the most suitable method of treatment. We present our experience and results of 90 operations performed during the past eight-year-period(1986-1993) including 10 halo-vest applications. The timing of operation was within 7 days posttrauma in 34.2%, 8-14 days in 27.4%, 15-28 days in 1.0%, and over 28 days in 27.4%. In 18 cases of upper(C1-3) cervical spine injuries, 23 operations were performed, all approached from the posterior. In 5 cases of lower(C4-7) cervical spine injuries, 67 operations were performed, the anterior approach used in 33 patients and the posterior approach in 18 patients. Halo-vest was applied in 6 patients with upper cervical spine injuries and in 4 patients with lower cervical spine injuries. The halo-vest was inadequate in maintaining the stability of the injured spine in 5 out of 0 cases. The complication rate was 23.3% in postrior approaches and 32.4% in anterior approaches. Overall, 27 complications(0%) occurred in 90 operations, and the reoperation rate was 16.4%(85 operations for 73 patients, except for the halo-vest applications). Internal fixation with a variety of devices has become a popular procedure for ervical spine injuries. Despite the popular and wide usage of such devices, the occurrence of complications and the need to reoperate has rendered the procedure to be applied with much caution regarding its technical aspects and possible problems it may pose. In our study, the rate of reoperation and complications following such procedures were quite high. We conclude that in choosing the most proper surgical approach for ervical spine injuries with minimal occurrence of any complications, a stringent criteria should be adhered to rather then easily select the more fashionable, new of fancy devices over the traditional techniques.

We present a retrospective study on the results of posterior instrumentation with various devices after thoracolumbar spinal injuries. From Jaunary 1985 to December 1990, we operated 61 patients in Soonchunhyang University Chonan Hospital. Fourty-six patients were followed at least three months(three to 40 months). Rod system was used in 21 patients and pedicle screw system was used in 27 patients. In two patients, both systems were used. We divided them into two group ; Group A for the patients operated with rod system and Group B for the patients operated with pedicluar screw system. We analysed and compared the results of these two groups. There were no significant differences in the age, sex, causes of injury, levels and types of injury, and the incidence of cord injury. The final wedge deformity was less severe in Group B than A(P<0.02). However, the final angular deformity did not significantly differ in two groups. The mean hospital stay of Group B was shorter than that of Group A, but the difference was not statistically significant. Although there was no statistical significance, the final wedge deformity was severe in patients who were older than 40 years of age, who follwed up for more than 300 days, and who had cord injury. The final wedge deformity and angular deformity were severe in patients whose preoperative deformity was great(P<0.05 and P<0.02, respectively). The angular deformity was also severe Group A, in patients who had cord injury, who followed up for more than 300 days, and who were younger than 40 years of age, but these differences lack the statistical significance. Although the rate of complication in Group B(40.7%) was higher than Group A(28.6%), this diference was not significant. The most common complication was rod displacement in Group A and screw fracute in Group B. Pedicle screw system was superior to the rod system in this study. Improving the instruments and accumulating clinical experiences, pedicle screw system will be an effective method for thracolumbar stabilization.

Acute subdural hematoma (ASDH), chronic subdural hematoma (CSDH) and subdural hygroma (SDG) occur in the subdural space, usually after trauma. We tried to find a certain relationship among these three traumatic subdural lesions in 436 consecutive patients. We included all subdural lesions regardless of whether they were main or not. We evaluated the distribution, age incidence and interval from injury to diagnosis of these lesions, and the frequency of new subdural lesions in each lesion. ASDH constituted 68.6%, SDG 15.8%, and CSDH 15.6%, Age incidence of CSDH was similar to that of SDG, but differed from that of ASDH. Mean interval from injury to diagnosis was 0.4 days in ASDH, 13.4 days in SDG, and 51.6 days in CSDH. Focal brain injuries accompanied in 37.5% of ASDH, 5.8% of SDG, and no CSDH. In ASDH, 2 recurrent ASDHs, 17 SDGs and 9 CSDHs occurred. In SDG, 3 postoperative ASDHs and 8 CSDHs occurred. In CSDH, 2 postoperative ASDHs, 2 SDGs and 1 CSDH occurred. These results suggest that the origin of CSDH is not only ASDH, but also SDG in upto a half of cases. SDG is produced as an epiphenomenon by separation of the dural border cell layer when the potential subdural space is sufficient. A half of CSDHs may originate from ASDHs. ASDH may occur in CSDH by either a repeated trauma or surgery. Such transformation or development of new lesions is a function of a premorbid condition and the dynamics between the absorption capacity and expansile force of the lesion.

Two cases of iatrogenically induced false aneurysm of the superficial temporal artery are presented. One patient showed partially filled aneurysmal sac, 1x1 cm sized, on the main trunk of left superficial temporal artery by external carotid artery angiography. Another patient showed aneurysmal dilatation, 3x2 cm sized, of the superficial temporal artery with direct injection of Urograffin into the pulsatile mass. Aneurysm excision is indicated to reduce the risk of hemorrhage from the subsequent head trauma, to relieve headache, and for any cosmetic defect. The authors have reviewed the literature and discussed the incidence, classification, pathogenesis, clinical and angiographic diagnosis, differential diagnosis, and treatment.

Although the prevalence of infectious disorders has been decreased, tuberculous infections are still common in this country. Therefore epidemiological data for the correct diagnosis of some spinal infections and proper selection of susceptible antibiotics are necessary. We presented a series of 40 patients with primary spinal infection dated from January 1990 to December 1994. Tuberculosis was the most common infection constituting 85% of this series, while pyogenic infection constituted only 10%, and primary discitis shared 5%. In a half of the tuberculous spondylitis, there were histories of previous tuberculosis except the vertebrae. We could identify the pathogenic organisms in only 47.5% o the cases(in 4 of 6 pyogenic infection and 15 of 34 tuberculous infection). Since it is difficult to differentiate the pyogenic and tuberculous infections by clinical or radiological features alone, some pyogenic infections might have been regarded as tuberculous, although the pyogenic spinal infections are rare. Nevertheless the tuberculous spinal infection outnumbered pyogenic ones in this country, which is similar to the patterns of other third-world countries. Therefore, correct identification of the microbial agent is important not only for the proper treatment but also to evaluate the patients of primary spinal infections in this country.
