To assess the prognostic factors of the femoral neck fractures in patients with CVA, we compared the survival rates in 12 cases of CVA group with 12 cases of non-CVA group and evaluated the various clinical factors of CVA group affect the mortality. All of the patients both CVA group and non- CVA group were treated hemiarthroplasty for femoral neck fractures between June 1990 and June 1992. The mean age was 68.9 years old in the CVA group and 69.3 years old in the non-CVA group. The mean follow-up periods were 32.8 months in the CVA group and 33.6 months in the non-CVA group. The results were as follows; 1. The incidence of the femoral neck fracture with CVA was 15%(12 cases among SO femoral neck fractures). 2. The survival rates in the CVA group at l-year, 2-year, and 3-year were 83.3%, 66.7%, and 58.3% respectively. In the non-CVA group, the survival rates were 83.3%, 75.0%, and 62.5%. 3. In the CVA group, serum total protein, nutritional index, hypertension, lung disease, and cardiac disease may be valuable prognostic factors. In conclusion, the pretraumatic patient's general physical condition could affect the mortality of femoral neck fracture in the CVA patients rather than CVA itself or postoperative status.

Osteoid osteoma is a relatively common benign tumor that most commonly affect the cortex of the long bone, Adolescent and young adult males are most frequently affected. It causes aching pain that worsens at night and commonly is relieved by aspirin. The typical radiographic appearance is a lucent nidus with surrounding dense cortical thickening. If the lesion is located in intra-articular cancellous bone, an osteoid osteoma may present with clinical findings that are more indicative of an inflammatory synovitis, and with atypical radiographic findings such as lack of both surrounding sclerosis and a lucent nidus. Therefore intra-articular osteoid osteoma may pose a diagnostic difficulty. Recently, we experienced 3 cases of intra-articular osteoid osteoma(2 humeral haed, 1 femoral head) and present them in detail.

Authors investigated the possible role of intravascular hypercoagulable states on the etiology of Kegg-Clave-Perthes diesease. Forty-five patients with Legg-Clave-Perthes disease(31 avascular stages and 14 reossification stages) and twenty-two normal control patients were subjected to study for evaluation of coagulation and fibrinolysis system by means of the tests which included antiphospholipid antibody(APA), Protein C, Protein S and antithrombin- III (AT- III) for evaluation of coagulation system, and tissue type PIasminogen activator(tPA), Plasminogen activator inhibitor(PAI), D-dimer for fibrinolytic system. APA increased significantly in Legg-Clave-Perthes patients(p=0.016) as compared with control group, while Protein C(p=0.040) and Protein S(P=0.0001) decreased significantly in Legg-Clave- Perthes disease. AT- III increased in Legg-Clave-Perthes disease(p=0.0000). In contrast, there were no statistically significant differences in PAI, tPA, D-dimer between the Legg-Clave-Perthes disease and control group. There were no differences in all parameters between the avascular stage and reossification stage in patients with Legg-Clave-Perthes disease, Suggestive of possible inherent effect in coagulation system(hypercoagulable states) which does not change with time. Based on the above findings authors presumed that hypercoagulable state may contribute to the development of Legg-Calve-Perthes disease. However, to elucidate the etiology of Legg-Calve-Perthes disease, further extensive investigation should be followed, which include the familial tendency of hypercoagulable state, relationship with other multifactorial causes such as alcohol and steroids, and confirmation of intravascular thrombosis or decreased blood perfusion in the femoral head. Also, the significance of abnormally elevated AT-III on the disease should be answered.

Long segmental fixation with TSRH posterior instrumentation for 19 patients who had unstable thoracolumbar fracture was performed between October 1992 and April 1995. The patients were followed for an average of 22 months. Measurements of the deformity angle, kyphosis, vertebral height, and the intervertebral angle were made. The patients were divided into 2 groups according to configurations of instruments for lower segmental fixation. For one group, only hooks were used, and for the others group pedicular screws and lateral offset hooks were used together at the same segment. Therefore, the purpose of this study is to anlyze the correctability following long segmental fixation and to compare one segmental fixation using both screws and lateral offset hook systems with two segmental fixation using hook systems for distal fixation. There was an overall correction of kyphosis at follow-up of 6.9degrees (27.1%) after a loss of 4.3degrees from operative correction. Overall correction of deformity angle was 8.2degrees (32.2%). Loss of vertebral height at final follow-up was 4.4%. And loss of intervertebral angle was 2.0degrees at follow-up. There was no difference of overall results between the hook group and the pedicular screw with lateral offset hook group. However, there was a significant improvement of the correction of kyphosis and restoration of vertebral height in patients who underwent operation within 7 days after injury, as compared to delayed operation. Therefore, the timing of surgery is the most important factor in order to correct the deformity caused by unstable thoracolumbar fractures. There was no significant loss of correction and no metallic failure. Therefore, rodding long with the method of one segment distal fixation using screws and lateral offset hook together can provide excellent correctability, maintenance of correction, preservation of distal lumbar joints, prevention of implant failure and complication.

7.Clinical Outcome After Surgical Correction of Severe Scoliosis.
The Journal of the Korean Orthopaedic Association 2001;36(1):39-44
PURPOSE: To determine the radiological, functional, and subjective outcome after stabilization in adult patients with severe scoliosis. MATERIALS AND METHODS: Eighteen adult patients with severe scoliosis underwent surgical correction. The radiological outcome was assessed by coronal and sagittal Cobb's angle, apical vertebral translation, and trunk deviation. The functional outcome was assessed by physical ability, locomotion, activities of daily living, and use of both hands. The subjective outcome was assessed by cosmetic satisfaction and costo-pelvic pain. RESULTS: Radiologically, mean correction of coronal curves were 28.7% in thoracic curves and 30.2% in lumbar. Average correction of sagittal curves were 29.4% and 16.8%, retrospectively. Mean correction of apical vertebral translation were 35% and 52.3%, retrospectively. Average correction of trunk deviation was 42.8%. In functional outcome, feeding ability and function of both extremities were improved significantly. 94.4% and 88.9% of patients were satisfactory significantly in cosmetic features and pain sensation. CONCLUSIONS: In this series, the surgical correction and stabilization of adult severe scoliosis resulted in much improvement in balancing of the trunk, improving function of upper extremities, and subjective satisfaction in the aspect of costo-pelvic pain and cosmesis.

STUDY DESIGN: The authors reviewed 14 patients with neurologic deficits caused by ossification of ligamentum flavum(OLF) of thoracic and thoracolumbar spine. OBJECTIVE: To evaluate the clinical and roentgenographic characteristics and suggest the treatment method of the OLF in the thoracic and thoracolumbar spine. SUMMARY OF LITERATURE REVIEW: The reported OLF mainly developed at the thoracolumbar area. It compressed the spinal cord and resulted to the symptoms of thoracic myelopathy. The methods of treatment were posterior decompression including laminectomy or laminoplasty, and sometimes anterior and posterior decompression, with or without fusion. The OLF was not common disease yet and many surgeons have met a problem in making the decision of the extent of posterior decompression multiple or selective. METHODS: The authors reviewed 14 patients with the OLF using clinical reports and roentgenographic studies. We checked the plain roentgenograms, computed tomograms, and magnetic resonance imagings. We performed the posterior decompression using total laminectomy without fusion. We divided three groups according to the operative methods. Group I included the patients with one or two levels of OLF treated with posterior extensive laminectomy. Group II included the patients with OLF in three or more levels, or combined other cord-compressing diseases. They had been treated with multiple posterior or anterior decompression for the entire cord-compressing levels. Group III included the patients with same conditions as group II but they had been treated with selective decompression for the mainly symptomatic levels of OLF. RESULTS: We found the OLF at 54 segments of 14 patients. The involvement of OLF was 29 segments(53.7%) in thoracolumbar and 25 segments(46.3%) in thoracic area. The most commonly involved segment was T10-11(16.7%) and the second was T11-12(14.8%). Clinically the most common neurologic deficit was motor weakness and sensory deficit. The most symptomatic level of OLF was T10-11 and T12-Ll segment(28.6% at each) and the next was T11-12 segment(21.4%). We got the favorable results in group I and group III. But the final results of group II were not good. CONCLUSION: The OLF was most common at the thoracolumbar area and the symptoms and signs were revealed same as those of the thoracic myelopathy. We obtained favorable clinical results after posterior laminectomy without fusion in cases with the OLF in 1-2 segments. In the cases with multiple OLF in three or more segments, or the cases with other cord-compressing diseases, we could get more favorable results in the patients with the selective decompression than the patients with multiple decompression for the entire cord-compressing diseases.

STUDY DESIGN: The authors reviewed the dural tears in the thoracolumbar fractures treated surgically. OBJECTIVES: To evaluate the incidence and the predictive values for the presence of dural tears in the thoracolumbar fractures. SUMMARY OF LITERATURE REVIEW: Many authors reported that the dural tear was usually related to the thoracolumbar fractures especially with laminar fracture and neurologic deficit. The dural tears may lead complications such as the entrapment of spinal nerve root, delayed wound healing, cerebrospinal fluid fistula, and myelomeningocele. Previous reports emphasized posterior approach to confirm and treat the dural tears using laminectomy. So it is very important that surgeons should identify the presence of dural tear preoperatiyely to determine the surgical approach and treatment options. MATERIALS AND METHODS: The authors reviewed 22 patients of thoracolumbar fractures treated with posterior laminectomy, posterior decompression, posterolateral fusion, and instntmentation from August 1993 to August 1996. The follow-up period was minimally 12 months. We checked the canal compromise, the injury of the posterior column including laminar fracture and ligamental injury, and neurologic deficits as the predictive values. The statistical analysis was done to evaluate the relationship between the dural tear and the predictive values. RESULTS: The incidence of dural tear was 54.4% of the thoracolumbar fractures. The canal encroachment, the injury of the posterior column, and the neurologic deficits were not significantly related with the dural tears in statistical analysis. But we could find the tendency that is related to the dural tear and posterior column injury. CONCLUSION: The authors concluded that we could find the possible presence of dural tears in the severe thoracoiumbar which were needed the surgical treatment and we could suggest the injury of posterior column was a possible value that could predict the presence of dural tear.

Henoch-Sch nlein purpura is a small-vessel vasculitis characterized by palpable purpura, abdominal pain, hematuria and arthralgia. Joint involvement occurs in 2/3 of the cases and the joint symptoms are misapprehended as an orthopaedic problem because they are often severe and occurs before characteristic purpura. It has been reported that the joint symptoms can be improved without any sequelae. But, recently some authors suggest that severe joint destruction can occur when combined with rheumatoid arthritis and the patients are FILA-DR4 positive. So, the regular follow-up for joint symptoms and screening test for the risky patients having possibility for progression of arthritis are required. In order to increase the attention of the orthopaedic surgeons on this disease and study the progression of joint symptoms, possibility of development of screening test for the risky patients and the characterisitics of the disease, we analyzed the 58 patients of Henoch-Sch nlein purpura. The following results were obtained. Among 58 patients 34 cases were male and 25 cases were female, 5 to 10-year-old children were affected more frequently and the disease occurs frequently in spring and winter season. Joint symptoms developed in 22/58 patients(37.9%) and occurs before characteristic purpura in 5/22 patients(22.7%) among the joint symptom-developed patients. Knee and ankle were affected in most patients and the inflammatory signs such as high fever, leukocytosis and elevated ESR were accompanied with joint symptom, so it resembled the symptoms and signs of pyogenic arthritis. Most of the patients recovered without remaining sequelae but 9 patients(15.5%) among joint symptom-developed patients complained repeated attacks of arthralgia. The HLA B27 were all positive in those patients. So, it was assumed that the joint symptom in Henoch-Sch nlein purpura has a correlation with genetic environment and through the broad prospective study, the HLA typing can be a screening test for the risky group prone to suffer from repeated attack or aggravation of arthritis.
