The Marfan syndrome, a rare disease causing a marked decrease in life expectancy by involving the skeletal, ocular, and cardiovascular systems, is known as a connective tissue disorder that is inherited autosomal dominant. The cardiovascular complications directly related to the cause of death are associated with more than 90% of the Marfan syndrome. Aortic aneurysm with rupture could occur because of dilatation of aorta due to defect of media. Aortic and mitral insufficiency, mitral valve prolapse, bacterial endocarditis, arrhythmia, and aneurysm of interatrial septum are also frequently observed. A few literatures were reported domestically pertaining to the Marfan syndrome thus far, and there are increased discoveries of cardiovascular complications of the syndrome with the application of echocardiogram. However, the Marfan syndrome with LA myxoma has never been reported both domestically and internationally(INDEX MEDICUS, 1966-1989). Therefore we hereby report a case of the Marfan syndrome with LA myxoma from the observation of a patient who was admitted to Eulji General Hospital at Taejeon i August of 1989.

Degloving injuries of the fingers receive digital sensory nerve damage as well as digital artery damage together with degloving of the finger skin at the time of injury. Although the finger is well covered with skin and the joint motion has completely recovered after the injury, if there is no sensation in the finger tip problems remain. From October, 1982 to December, 1985 Dong San Medical Center, Keimyung University did free digital sensory nerve grafts on 11 cases using the sural nerve. Follow up studies which lasted from 10 to 39 months showed good results. Therefore this free digital nerve graft operation is considered to be a favourable mothod in obtaining sensation for digital degloving injuries.

It is essential to define the accurate location and extent of bony bridge in relation to the epiphyseal plate for operation of partial epiphyseal plate closure by bony bridge resection. Since magnetic resonance imaging(MRI) provides excellent tissue contrast and multiplaner image, it could be applied to the diagnosis and mapping of bony bridge of epiphyseal plate. A thirteen year old female with post-traumatic epiphyseal injury of ankle was diagnosed by MRI. We could assess the bony bridge accurately by direct sagittal and coronal images and excellent tissue contrast of MRI.

The Palmaris longus tendon is important not because of its function but because of its usefulness as a donor tendon. Variations in the palmaris longus muscle ar elfrequent and the most common variation of the muscle is its absence. The incidence of absence of this muscle varies in different racial groups. Reinmann and his coworkers found the palmaris longus muscle absent in 12.9% of in their 1,600 limbs surgery. We have experiened 307 cases of palmaris longus graft surgery and found that there were 4 cases of absence of the palmaris longus tendon. We examined 2,000 limbs of Korean to see the presence of the palmaris longus muscle. Among 1,000 persons, the muscle was absent bilaterally in 11 persons(1.1%). It was absent unilaterally in 32 persons(3.2%). The probability that the muscle is absent in any single limb is 2.7%. There was no significant differences in the incidence of absence by sex or right and left side.

During the period from January 1980 to September 1988, 59 patients suffering from brachial plexus injury, have admitted to Seoul National University Hospital. Fifty-four patients were male and 5 patients were female, and age ranged from 6 to 58 years (mean:26.8 years). The most common cause of injury was traffic accident accounting for 66% (39patient), and among them 24 patients(62%) had the motor cycle accident. Birth injury, stab or gun shot wound, fall down and industrial hazard were following causes. Fracture and dislocation of involved limb accompanied in 19 patients(32%) and 2 patients of arterial injury were also found. EMG and cervicsl myelography with or without CT were performed in almost all the patients and MRI was performed in selected patients. Forty-five patients(76%) had supra-clavicular lesion and 14 patients (24%) had infra-clavicular lesion. In supra-clavicular lesion, upper roots or whole roots were involved in most of cases. Forty-nine cases were treated with conservative treatment for more than 8 months and operative procedures were performed in 36 cases. In operative cases, 30 patients were followed up for more than 1 year (average 24.3 months). Signs of root avulsion were found in 25 out of 31 cases of cervical myelography. MRI was performed in 7 cases, but it was inconclusive in diagnosis of root involvement. Infra-clavicular lesion showed better prognosis than supra-clavicular lesion. In supra-clavicular lesion, upper root involvement had the best prognosis. A pseudocyst detected by myelography usually precluded recovery in the root at the level of pseudocyst. Result of reparative treatment was better than that of conservative treatment. Overall satisfactory result in reparative treatment was 36%. However, if we include neurological improvement, positive result was 53%. Complete recovery was gained in half cases of neurolysis and other half showed no recovery, but all the cases of neurotization showed poor result. Reconstructive surgery including arthrodesis or muscle transfer can be effective treatment method, if it is performed properly on a selective patient.

Adenocarcionma of fetal type is in lung is a newly recognized malignant tumor sharing morphologic features with the epithelial component of the pulmonary blastoma devoid of sarcomatous component. We present a case of adenocarcinoma of fetal type in a 28-year-old female, consisting of numerous branching tubules or glands and morula-like epithelial complexes. Histologically, the tubules and glands were composed of glycogne-rich nonciliated epithelial cells showing in part argyrophilia. Some of tubular and morula-like epithelial cells revealed immunoreactivity for neuron-specific enolase. We report this case with a review of literatures with special references on the histogenisis. This report is the pathologically confirmed second case of the pulmonary adenocarcinoma of fetal type in Korea, following the report of Cho and Lee, 1990.

Many kinds of lumbar diseases cause lumbar segmental instability and/or limitation of motion. But, there is no reliable method for measuring accurate trunk motion. In order to measure relative trunk motion respect to the pelvis in vitro, external linkage type of spine motion analyzer was developed. Special programs for calculation of the relative angular motion and graphical display were also developed. The developed device was tested to compare spine motion pattern between 15 normal volunteers and 18 lumbar fusion patients in flexion, extension, lateral bending and axial rotation. It was rather simple and reliable method for spine motion analysis. And it was possible to measure not only angular displacement but also angular velocity and angular acceleration. There were more coupling motions in lateral bending and axial rotation than in flexion and extension. Compared to the normal subjects, patients showed different angular motion, especially in the angular acceleration. Optimal trajectory of the trunk motion derived from mathematical model in flexion and extension matched well with measurement for normal subjects.

The biomechanical responses, such as nucleus pulposus pressure, facet contact force, stress distribution among ligaments in the cervical spine under static loading like flexion and extension, were examined with 3-D nonlinear finite element model. Finite element model consisted of whole cervical spines with intact discs and ligaments was developed from 1mm thick CT-cross sections of a 25-year-old healthy young man. Geometrical nonlinearity was considered for the large deformation and ABAQUS package was used for calculation. Results were verified comparing with those of existing in vivo and in vitro experiments. Results indicated that, developed cervical spine FEM was well consistent with other experiments. Nucleus pulposus pressure increased in flexion and extension more in lower cervical region. Facet contact force increased more in lower cervical spine in extension. In addition, capsular ligament was the most important one among 7 cervical ligaments surrounding cervical spine both in flexion and extension. We could better understand the biomechanics of whole cervical spine with developed finite element model and it might be applied to dynamic or postoperative study.
