OBJECTIVE: The aim of this study is to determine the factors influencing the surgical outcome following craniotomy for head injury and to establish the criteria for surgical intervention in the age of 65 years or older. METHODS: We retrospectively investigated the mechanism of injury, types of computed tomography lesions, Glassgow coma scale(GCS) score at admission, pupillary reactivity, past medical history and surgical outcome following craniotomy in the elderly during 8 year period. RESULTS: There were 35 men and 21 women with a mean age of 70.7 years(range 65-87 years). The mortality rate at discharge was 58.9%. Good outcome was achieved only in 25 percent of the patients. The cause of injury did not affect on the surgical outcome. All of 19 patients with GCS of 5 or less at admission had poor outcome. Outcome was significantly worse in older patients(more than 75 years) compare to younger patients(less than 75 years). Ninety percent of the patients with pupillary abnormality had poor outcome, whereas 57.7 percent of the patients with bilateral reactive pupil had poor outcome. Past medical history did not affect on the surgical outcome following craniotomy. CONCLUSION: Surgical outcome is unexceptionally poor in the elderly head-injuried patients if the age is 75 years old or older, the GCS is 5 or less and the pupil is bilaterally dilated. Craniotomy under those circumstances is not desirable.

The most feared complication of left ventricular thrombus (LVT) is the occurrence of systemic thromboembolic events, especially in the brain. Herein, we report a patient with severe sepsis who suffered recurrent devastating embolic stroke. Transthoracic echocardiography revealed apical ballooning of the left ventricle with a huge LVT, which had not been observed in chest computed tomography before the stroke. This case emphasizes the importance of serial cardiac evaluation in patients with stroke and severe medical illness.

It is never easy to assess the rate of disability from spinal injuries objectively. One reason is that the pain is an unmeasurable subjective symptom, and the other is that the disability is usually not confirmed by or correlated with radiological or laboratory examinations. The disability is an essentially subjective inconvenience or limitation, which is hard to measure objectively. However, compensation or reparation requires a scale to measure this unmeasurable disability, even with a universal validity and equity. There are several guidelines or criteria for a quantitative assessment of the disability. They differ from each other and have their own advantages and disadvantages. This difference may cause confusion or inequity. To improve the validity and equity, we propose a new design for the disability evaluation in patients with spinal injuries. We reviewed the Korean law for compensation in industrial accidents, McBride's disability table, the guideline proposed by American Medical Association, and a impairment rating table. Disabilities resulting from spinal injuries were classified into three types, i.e., morphologic sequelae(deformity), functional sequelae(dysfunction), and others. Only objective findings were considered as criteria for rating the disability. Disability resulting from deformity were rated from 0 to 20% by the degree of compression. Dysfunction can be rated by the number of lost motion segment from 10 to 60%. Disability from other compensable spinal pain were rated by objective physical findings or neurologic deficit from 0 to 25%. By eliminating the subjective or intentional complaints, this design can be a useful method minimizing the differences from the multiple examiners.

Mortality after cervical spine injury is reportes as high as 15~30%, and it is intimately related to the initial cardiopulmonary function. We analysed the cause of death and initial cardiopulmonary function in 30 patients who expired at Soonchunhyang University Chonan Hospital after cervical spine injury between 1986 and 1993. Overall 42 patients(20.5%) expired in 205 patients with cervical spine injuries. Except 12 cases with concomitant fatal head injury and/or multiple systemic injuries, the mortality rate of cervical spine injury was 15.5%. It was 28.9% in cases with cord injury, and 2.1% in cases without cord injury. Male to female ratio was 5 : 1. Fifth to seventh decades constituted 63.3%. Common causes of spinal injury were in-car accident(46.7%) and fall/slip(36.7%). The level of spinal injury was above C5(upper cervical group ; UCG(55.6%) than the LCG(25.0%). Associated injuries were found in 66.7%, and the head injury was the most common one. The injury severity score was over 25 in 93.3%. The higher the score, the earlier the patients expired(Fisher's test, P<0.05). On arrival, hypotension(systolic blood pressure below 70 mmHg), bradycardia(less than 60/min), and respiratory arrest was found in 23.3%, 26.7%, and 16.7%, respectively. The episode of bradycardia was found in 56.7%. It was more common in cases of the early death(69.2%) than those of the late death(47.1%). Hypoxia, hypercarbia, and acidosis was observed in 19.2%, 7.7% and 5.38%, respectively. Respiratory failure was responsible for the majority(86.7%) of death. In UCG and cases of the early death, primary respiratory dysfunction was the main cause of death, while in LCG and cases of the death, pulmonary complication was the major reason(Fisher's test, P<0.01, respectively.

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.

Recent advances in diagnosis and therapy for head injury have brought some changes in concepts, definition of the terms, therapeutic methods and the duration of treatment. In medical certificates, the diagnosis and duration of treatment also need to be changed according to the new concepts. Mixed use of the terms according to the classic and the new concepts may cause confusion. We investigated with a questionnaire to assess the acceptability of the new concepts of head injury, and seeked for a plan to avoid possible confusion in medical certificates. We sent questionnaires for diagnosis and duration of treatment of 10 given examples of head injury to 367 neurosurgeons whose addresses could be identified. Questionnaires were answered by 52 neurosurgeons. The diagnosis described in the questionnaires showed wide variability with a range of 10 to 32 different descriptions, on average 16.8 different descriptions for each case. Duration of treatment also revealed great discrepancy. Coefficients of variation for duration of treatment varied from 33.44% to 54.37%. Cerebral contusion was the most commonly used term. It was described in every 10 given examples, and to take an average, 32.3 neurosurgeons used cerebral contusion or each case. To avoid possible confusion in medical certificates, it is necessary to make a guide for medical certificates for head injuries according to the new concepts, and a chance of training of this guide should be provided.

Journal of Korean Medical Science 1996;11(1):55-63
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.
