4.Observations of Normal Optic Foramen in Korean.
Journal of the Korean Ophthalmological Society 1980;21(4):473-479
The optic canal begins to be formed by the fusion of two roots of the lesser wing of sphenoid. It is a funnel shaped tube measuring about 4~9 mm long and 4~6 mm broad. But the canal shows considerable variations in its caliber. The optic canal attains its full size at 3 and 5 years of age. Since the radiograms of the optic canal was taken in the living human subject first by Rhese (1911), various radiographic methods have been revised by many other scholars. The development of the radiographic technique made it possible not only to evaluate the morphology (size, shape and its symmetry) of the canal but also to find its pathology such as fracture, fissure, callus formation and abnormal shadow. In the radiogram of the optic foramen the most shows a quadrant of a circle in shape, being more or less elliptical, circular or quadrangular. The two principal diameters were measured: the A diameter, which is principal downward and outward at an angle, and the B diameter, which is at right angle to A (Goalwin, 1924). The average A diameter of normal adult optic foramen was reported to be 4.3 mm and the B 4.4 mm by Goalwin (1926, 1927). The average transverse diameter of normal optic foramen was said to be 5.5 mm by Harwood-Nash (1970). In Korea, normal Korean optic canal has never been surveyed roentgenologically. Theshape, size and symmetry of 312 normal optic foramen of 156 Korean were studied in the radiogram taken by Goalwin's method from January, 1974 to December, 1979. 1. The shape of the optic foramen was oval (42.4%), circular (28.4%), a quadrant of a circle (19.8%) and elliptical (9.4%). And 86% of the foramen showed symmetrical in shape. 2. The size of the optic foramen was as follows; A diameter is 4.73 mm (right), 4. 76mm (left); B diameter 5.00 mm (right), 5.06 mm (left); horizontal diameter 4.71 mm (right), 4.65 mm (left); vertical diameter 4.93 mm (right), 4.97 mm (left). Differnce between the diameters of the foramen measured by means of roentgenography and the actual diameter calculated by Goalwin's formula was 0.03~0.04 mm. 3. The diameter of optic foramen seemed to attain its full size at 5 years of age. The average size of each diameter before age 5 was shorter than that after age 5 by 0.44~0.96 mm (p<0.006). 4. There were no appreciable variations in size and shape depending on sex. 5. The optic foramen was same on the two sides (13.8%). Differences of 5% or less were noted in 41.8%; differences of 20% or less shown in 89.1%. 6. Differences between the diameters (A, B, vertical of the foramen of the right and that of the left were less in the symmetrical foramen than asymmetrical (p<0.04).

callus foemation was observed in both groups. New bone formation of conventional bur preceded that of Er:YAG laser, but there was no significance. And thermal injury was not observed in both groups. In 8 weeks after osteotomy, the osteotomy site was shown like almost normal bone by remodelling process. New bone formation of conventional bur preceded that of Er:YAG laser, but there was no significance stastically. Thermal injury was not observed in both groups. It can be concluded that there is no considerable difference in healing effect between Er:YAG laser and conventional bur, so Er:YAG laser is available to perform the osteotomy.]]>

6.Radiologic Study of Torsion Type of Supracondylar Fracture of Humerus in Children
The Journal of the Korean Orthopaedic Association 1989;24(5):1517-1525
1. The author found that the periosteal callus was formed on lateral side of the fracture in two cases of three posteromedially displaced supracondylar fracture of the humerus associated with fracture of distal end of ipsilateral forearm which were considered as the torsion fracture. 2. The above result was peculiar out come of the torsion fracture. 3. The characteristic radiologic findings of the torsion fracture are. 1) The fracture line of the proximal fragment is transverse and irregular(bursting). 2) Multiple longitudinal splitting and waving on entire fracture line of distal fragment. 4. Twenty eight cases of 236 cases of extension varus fracture supracondylar fracture of humerus were identified with torsion fracture. 5. The torsion fracture was combined with hyperextension fracture in 3 cases, extension-adduction fracture in 6 cases, shearing fracture by direct blow on anterior aspect of flexed elbow in 12 cases, and shearing fracture by backward thrust of forearm in 4 cases.

Acute unstable tibial shaft fractures are common in these days of high energy trauma. There are many options for this common and complicated fracture. Flexible intramedullary nailing using closed technique is prevalent in that this has much technical, functional, and physiological advantages. We reviewed 51 cases of acute tibial shaft fractures treated with flexible intramedullary nailing. There were 3 nonunions (6%), and two refractures. Among 46 united cases, 8 cases (17 %) showed no bridging callus formation within 20 weeks. Followings are the results of average time reaching each of radiological bony progression stage for 46 united cases. l. Average time to earliest discernible callus formation (stage I) was 13.3 weeks (range:8-21 weeks). 2. Average time to definite and bridging callus formation (stage II) was 18.1 weeks (range:8-32 weeks). 3. Average time to some oblitetation of fracture line (stage III) was 32.8 weeks (range:17-50 weeks). 4. Average time to complete obliteration of fracture line (stage IV) was 14.0 months(range:12-18 months).

8.Treatment of Fracture of Shaft of Humerus by Ender Nailing

Authors presented the experience of Ender nail treatment for the humeral shaft fractures in 24 patients. The results of treatment in all were satisfactory, though there were four cases of delayed union. Bridging callus was formed at 8.2 weeks on an average. The average clinical union time was 14 weeks. No complications developed during nailing procedure. A case of radial nerve palsy after fracture recovered spontaneously. Longer nails which hit the end of medullary canal of distal fragment distracted the fracture gap, and resulted in delayed union in 4 cases. Therefore, it is recommended to use the proper size of nail to avoid the distraction effect of the inserted nail, and to use two nails at minimum for better fixation. However, when intramedullary Ender nailing is properly done, single nailing also can give consistently good anatomic and functional results.

Journal of Korean Foot and Ankle Society 2013;17(2):136-142
PURPOSE: To analyze the outcome of distal tibia fracture treated with the Distal Tibia LCP with combination of interfragmentary screw. MATERIALS AND METHODS: Between January 2008 and March 2012, data of 34 patients with fracture of distal tibia treated with the Distal Tibia LCP with or without combination of interfragmentary screws were reviewed. There were 17 males and 17 females with an average age of 51.8 years (range, 18~77 years). Radiographic union time and time from surgery until ability to full weight bearing were measured and compared. Callus index was measured as quotient of callus thickness and diameter of corticalis both in AP and sagittal direction. RESULTS: 12 fractures were treated with interfragmentary screws and 22 fractures were treated with bridging plate alone. In interfragmentary fixation group, time to full weight bearing was 14 weeks versus 15.75 weeks without screw. Callus index at bearing was not significantly lesser in patients with screw compated with those without, but callus index difference at posterative 4weeks was sigficant. Radiologic union time was 11.3 weeks in interfragmentary fixation group and 12.58 weeks without screw. CONCLUSION: The osteosynthesis with the Distal tibia LCP with combination of interfragmentary screw seems to be more stable in postoperative 4weeks than Distal tibia LCP alone, expecting to earlier ROM exercise and rehabilitation.

Journal of the Korean Fracture Society 2007;20(1):86-89
Costoclavicular syndrome is one of the four syndromes of thoracic outlet syndrome in which have similiar symptoms, and may result from cervical and thoracic scoliosis, formation of excessive callus or nonunion after fractures of clavicle or first rib. Conservative treatment may be offered. Surgical treatment includes scalenectomy with supraclavicular approach, transaxillary first rib resection with scalenectomy and correction of clavicular abnormality. The purpose of this paper is to evaluate the result of surgical intervention in costoclavicular syndrome of a 38-year old man with clavicular nonunion after an operation.
