Although the incidence of tuberculous arthritis of the hip is being decreased with improvement of hygiene and preventive measures and chemotheraphy, it remains as important disease in orthopedic surgery. In order to evaluate which treatment is best in the view of eradication of the tuberculosis and preservation of the function, seventy two patients of tuberculous arthritis of the hip who were treated at the Department of Orthopedic Surgery, Seoul University Hospital for periods of 14 years between January 1970 and August 1983 were analysed clinically. The results are as follows: 1. Age distribution showed that patients below 15 years were thirty (41.7%) and those above 16 years were forty two (58.3%). 2. Onset of the symptoms above 1 year occupied forty two patients (58.3%). 3. Duration of follow up is between 1 year and 14 years with average duration of 3.5 years. 4. Recurrence rate according to the modality of treatment was 12.9% as 4 cases among 31 cases of hip fusion group, 15,2% as 5 cases among 33 cases of synovectomy group, and 28.6% as 2 cases among 7 cases of conservative group. 5. Follow up of the functional evaluation of the hip was 92.9% of “above Fair” as 26 cases among 28 cases of synovectomy group, 60% of “above Fair” as 3 cases among 5 cases of conservetive treatment group, and 25.7% of “above Fair” as 9 cases among 35 cases of hip fusion group. 6. Although the recurrence rate of synovectomy group is a little higher than that of hip fusion group, synovectomy is a better treatment in the view of the preservation of the function of the hip considering Korean life style.

Through the review of 137 cases of ankle fracture treated and followed up in Department of Orthopedic Surgery, National Police Hospital, we got the following results. 1. Slipping was the most frequent cause of the fractures(45.3%). 2. Supination-external rotation type of Lauge-Hansen classification was more common than any other types(67.9%). 3. 94 cases out of 137 cases were treated by open reduction and internal fixation, and remaining 43 cases were treated conservatively. 4. The average duration of cast immobilization was 7.3 weeks for the operatively treated cases and 9.1 weeks for the conservatively treated cases. 5. The result of treatment was good or excellent in 87 cases(92.6%) of operatively treated 94 cases and in 36 cases(83.7%) of conservatively treated 43 cases. 6. We think that the anatomical reduction of the lateral malleolar or distal fibular fracture is necessary for better end results.

Elucidation of the mechanism of fracture seems to be important to prevent to it and determin the position on immobilization most conducive to union. The scaphoid is more susceptable to injury than any of other carpal bones due to its position in bridging the proximal and distal raws of carpal bones and the mechnism of fracture has been a subject of considerable controversy. Reviewing 20 cases of scaphoid nonunion, we incidentally had found that 4 patients had the history of striking a punch bag with the heads of the second and third metacarpals (Punching injury), and a review of the literatures failed to find any reports of such an injury as a mechanism of fracture. On a scale, the wrist was subjected to progressive loading via the heads of the second and third metacarpals and lateral roentgenograms of the wrist were obtained at Okg, 20kg and 35kg and we measured the carpal angles. With progressive loading there is a volar flexion of proximal carpal raw and the volar flexion of scaphoid is smaller than that of lunate. We believed that the violent impact applied at the second and third metacarpal heads forced the scaphoid into the position of extreme dorsiflexion as compared with lunate, so compression force is exerted on the dorsal side of scaphoid and tension on volar side leading the fracture of scaphoid. We also recognized that the fracture of the scaphoid could be occurred by the compression and shearing force of capitate and the bending force of volar radiocapitate ligament.

The predictive accuracy of the SRK and SRKII formulas were compared in 113 pseudophakic eyes who had extracapsular cataract extraction with implantation of same type of posterior chamber IOL from Feburary 1990 to March 1991. These patients were folio we red up for at least 2 months postoperatively. Their best corrected visual acuities were above 0.5 and their astigmatisms were below 3 diopters by spectacles correction at the time of the last refraction. The results were as follows. 1. Overall, there were no significant differences in predictive accuracy between SRK and SRKII formulas. 2. The revised constant A for same type of implatnts, which constant A was 118.8. was 117.4 The SRK and SRKII formulas with revised constant A were more accurate than conventional formulas(p<0.001). 3. Our results suggested the constant A was to be revised appropriately according to the surgeon's individual regression analysis when using SRK or SRKII formulas for the calculation of intraocular lens power in Koreans.

Vitelliform macular dystrophy, adult type, is a type of pattern dystrophies of the pigment epithelium characterized by autosomal daminant inheritance, mid-life onset and small, round or oval, yellow deposits located at the level of the pigment epithelium. The authors report a case of this dystrophy which showed small yellow round lesion measuring 1/4-1/3 D.D. within the macula, normal electroretinogram, subnormal electrooculogram light-peak/dark-traugh ratio. typical irregular ring-like transmitted fluorescence surrounding the central non-fluorescent Iesion and leakage from perifoveal capillaries on fluorescent angiogram.

Angiosarcoma is a rare malignant vascular tumor of endothelial cell origin. Most lesions of cutaneous angiosarcoma occur over the face and scalp. We experienced a case of angiosarcoma of the scalp in a 63-year-old man. Multiple pea-sized erythematous papules and nodules developed on the forehead 6 months ago. Thereafter, the lesions have extended to make violaceous, compressible and hemorrhagic plaques. On histologic examination, there were irregular, often anastomosing vascular channels lined by the atypical endothelial cells in the dermis.
