The displaced femoral neck fracture continues to be a difficult problems such as high percentage of avascular necrosis and non-union. Compression hip screw was designed to aliow firm impaction at the time of operation and secondarily, for continued impaction if resorption occurs at the fracture line during healing. 22 cases of femoral neck fracture treated by compression hip screw in the department of orthopaedic surgery at National Medical Center were analyzed, and results were as follow. 1. The average of patient was fifty-three years, and man was predominant. 2. Average 8.9 days was elapsed from initial injury to hospital, and good results were observed in the cases of operation within 3 days. 3. The end results were good when the fragment was reduced within 165°–180° of Garden's angle in A-P film and 20° of anterior and posterior angulation in lateral film. 4. The good results were observed in the position of the screw center and low in A-P film, and center and posterior in lateral film. 5. The positive findings of the intraosseous-venogram was observed in 6 weeks from operation and apparent in all cases done after 6 months. 6. Bony union was obtained within 5.9 months, and avascular necrosis was established in 29 months. 7. Developed 3 avascular necrosis, 1 non-union, and 2 degenerative arthritis of 22 cases.

Over twenty per cent of adult knees have a synovial plica which always has possibility of changes into pathologic synovial plica symptomes and signs resembling those of other common internal derangement of the knee joint. Especially the young active patient who has a history of trauma to the knee should once be suspected incarcerated synovial plica not only the possibility of internal derangement. Four cases of symptomatic synovial plica experienced by authors are reported with available references.

A quantitative assay was performed on the effects of gamma-irradiation (30-300 Gy) on intracellular proliferation of Toxoplasma gondii RH tachyzoites in human leukemic HL-60 cells and murine peritoneal macrophages by means of 3H-uracil uptake assay. Infected non- irradiation group (NI) and uninfected group (incubating only host cells) were prepared. The 3H-uracil uptake by tachyzoites of NI group 12-24 hrs after infection was 2,190-4,787 counts per minute for macrophages and 2,967-8,254 for HL-60 cells, whereas the irradiated tachyzoites revealed only 381-703 (100 Gy) and 218-408 (300 Gy) for macrophages, and 1,911-2,618 (30 Gy), 1,253-1,384 (70 Gy), 1,013-1,090 (100 Gy), and 483-588 (300 Gy) for HL-60 cells. The proliferation inhibition rate was similar in macrophages and HL-60 cells, for example, 89-94% and 80-94% respectively by 300 Gy, 12-24 hrs after infection. It is concluded that RH tachyzoites of T. gondii are severely affected by gamma-irradiation in their capability of intracellular proliferation.

The urethral polyp is relatively unusual lesion but recently, has been reported more frequently Polyps of the anterior urethra are less common than those of the posterior urethra. The lesion is usually encountered in the young child but has occurred in the adult. Recently, we found two cases of urethral polyp. So, we report these with a brief review of the literature.

STUDY DESIGN: Clinical and radiographic results of spine fracutre treated with pedicle screws and hooks were reviewed. OBJECTIVES: Evaluate the efficacy of tile pedicle screw and hook for thoracolumar bursting fracture. SUMMARY OF LITERATURE REVIEW: Despite of the mechanical advantage of the pedicle screw, the metal failure in short segment fusion has been reported. A biomechanical study showed additional laminar hook increased rotational strength. MATERIALS AND METHODS: Between 1994 and 1996, seventeen patients who had a Denis type B bursting fracture of the thoracolumbar spine were treated by posterior instrumentation with pedicle screws and laminar hooks and auterior interbody fusion after partial corpectomy. They have been followed for an average of 13.4 months. RESULTS: At last follow-up, radiographs showed successful fusion of the injured spinal segment in all patient. The subsidence of grafts which were used In anterior interbody fusion was an average of 0.76mm. There was a loss of 2.6 degrees on average in the correction of the kyphosis. No patients had screw breakage or loosening. CONCLUSIONS: We concluded that posterior fixation with screws and hooks, anterior decompression by partial corpectomy, and strut-grafting in patient who had a Denis type B bursting frafture of the thoracolumbar spine yielded good radiographic and functional results.
