Computerized Tomography in Orthopedic Surgery / 대한정형외과학회잡지

The utility of computerized tomogaphy in the study of the anatomy, and pathology of the musculoskeletal system has been the subject of considerable interest since the introduction of CT scanning. It provides an accurate and detailed cross-sectional image of normal anatomical structures and shows the relation of masses to these structures. In order to assess the utility of computed tomography, we analyzed the 92 clinical cases. We divided our experience into three major categories: spinal lesios, pelvic (including hip) lesions, and lesions of extremities. The advent of a new prototype scanning device has made it possible to exam a variety of abonormalities in the orthopedic diseases in a manner not previously possible.

Treatment of Femoral Neck Fracture (Twenty-nine Cases Treated by Multiple Knowles Pinning and Compression Hip Screw) / 대한정형외과학회잡지

It has been emphasized that treatment of hemoral neck fracture is early anatomical reduction and rigid internal fixation to reduce severe complications such as avascular necrosis or non-union.Operative treatment were developed recently with development of radiological technique. This study reviewed twenty-nine patients of femoral neck fracture treated by internal fixation between December 1973 and December 1979. There are eleven casesof Garden's stage I or II fracture with multiple Knowles pinning and eighteen cases (All Gardens stage) treated with compression hip screw, and followed for a minimum of nine months with an average eighteen months. The results were as follows; 1. Eleven cases with minimal displaced fracture (Garden's stage I or II) treated by multiple Knowles pinning were revealed good results. 2. In total eighteen cases treated by compression hip screw, nine cases (Garden's stage I or II) were revealed good results and other nine cases (Garden's stage I or II) were revealed fair or poor results. 3. Eleven cases of mlutiple Knowles pinning and nine case of compressian hip screw used for undisplaced fracture (Garden's stage I or II) were revealed good results without regard to internal fixation devices. 4. Avascular necrosis were four cases in nine cases(44%) of displaced fracture. 5. Non-union were not found in this aeries.

Posteromedial Release in Infancy for Resistant Congenital Clubfoot / 대한정형외과학회잡지

Ten feet from 6 idiopathic congenltal clubfoot patients which had failed to respond to conservative mearsured were treated by aggreasive posteromedial release during infancy with generally good results. A modltication of Denis-Browne splint by splitting both aides and using dial lock to hold the foot still ln correeted position was found quite useful for post-operative maintenance.

Free Toe-to-Thumb Transplantation with Microsurgical Technique / 대한정형외과학회잡지

Although procedures to reproduce the lost thumb through osteoplastic reconstruction and adjacent finger transfer operations appeared reasonably successful in providing for better prehension, nonetheless the methods lacked predictabiiity and too often the results were unacceptable esthetically. In recent years the development of microsurgery and surgical experiences has made it possible to free one stage transplantation of toe to replace missing thumb. Based on our past experiences with limb replantation since 1975, we accomplished the first toe to thumb transplantation done in Korea on October 28, 1978. Therafter we succeeded in one stage toe-to-thumb transplanatation in five cases. The shortest follow up period was thirteen months, and the longest, twenty-three months. One cases was excluded in this report due to short follow up period. Excellent results were achieved in all cases. There were no limping or pain while walking after removal of great toes or second toe. Great toe transplantation is more favorable donor area than second toe in toe-to-thumb transplantation. Free toe-to-thumb transplantation on making a thumb in missing thumb is the most excellent method of thumb reconstruction, but skillful technique and specialized microsurgical training is mandatory.

CAT Guided Needle Biopsy of Spinal Lesions / 대한정형외과학회잡지

The utility of computed axial tomography(CAT) in the diagnosis of spinal disorders has been the subject of considerable interest since the introduction of CAT scanning. Computed tomographic guided needle biopsy of 12 consecutive patients with a variety of undermined spinal disorders resulted in a 100% yield of positive tissue diagnoses, without signlficant complications. The principal advantage of cat guidance is the continuous direct observation of the needle tip position in relation to the target volume. We think that the application of computed tomographic guided needle biopsy in the lesions of the spine is of great value, because it is the single most accurate method of obtaining diagnosis other than by open surgical biopsy.
