Since 1954 when the first biodegradable polymer, polyglycolic acid(PGA), was synthesized, many different biodegradable and tissue-tolerant materials have been invested and studied for internal fixation devices. The use of biodegradable materials for the internal fixation of fractures would avoid the need for later removal of the implant. However, problems of a physical and chemical nature have delayed the development of biodegradable implants applicable to fracture management. The authors reviewed 17 cases in which the absorbable pins made of poly-p-dioxanone were used for internal fixation at Seoul National University Hospital between December, 1987 and September, 1989, and report on 11 patients who had at least 6 months follow-up(average 9.1 months). The results were graded as excellent(5 cases), good(4 cases), poor(0 case), and questionable(2 cases). In the 9 cases where the absorbable pins were used for internal fixation of the intraarticular fractures or defects, satisfactory(excellent or good) results were obtained. In the 2 cases where the absorbable pins were used for intramedullary nailing, the role of the pins was questionable. There were no complications such as wound sinus formation, secondary displacement of the fragemts and delayed union or nonunion.

Biopsy has proved to be of value in the diagnosis of many inflammatory and malignant diseases, and needle biopsy of the synovial membrane in arthritis is well established and often employed as the final diagnostic aid in patient with joint disease. Authors have carried out synovial needle biopsy in 76 joints with Franklin-Silverman needle used commonly in liver biopsy. The results obtained were as followa; 1) Of seventy five biopsies attempted, adequate amount of tiasue was obtained in 51 of 53 knee cases (96.2%), 11 of 14 wrists (78.6%). 3 of 5 elbows (60%), 1 of 3 ankles (33.3%). Adequate amount of tissue was obtained in 66 cases and the overall succese rate was 88%. 2) Histopathological diagnosis was made in 53 of 75 cases (70.7%). In 12 cases, correct specimens were obtained but proved to be incompatible with the diagnosis done by either clinical data or open biopsy. 3) Histopathological diagnoses were made in 25 of 35 cases of rheumatoid arthritis (71.4%) 14 of 18 cases of tuberculous arthritis (77.8%), 7 of 13 cases of degenerative arthritis (53,8%), 4 of 6 cases of suppurative arthritis (66.7%), 2 cases of traumatic arthritis (100%), and one case of villonodular synovitis (100%). 4) The complications resulting from this proedure were pare; mild transient hemarthrosis was found in only 5 cases We also discovered that for an accurate diagnosis multiple specimens should be obtained because otherwise the specimens were too small to interprete histopathologically. In addition we concluded that the success rate depended not upon the sorts of needle used but rather more upon the biopsy technique. Franklin-Silverman needle biopsy proved to be a simple, safe and reliable procedure for diagnosis of the synovial diseases in which conventional arthrotomy is inadvisable and other diagnostic procedures are inadequate.

This study was planned by the necessities of basic information about the effects of Korean Ginseng upon fracture healing and biomechanical properties of bone. Three hundred white mice were used for this study, and we could have tested the biomechanical properties in one hundred and nintyfour. The bones of the white mice were evaluated by testing gross stability, radiological appearance, and biomechanical properties. It appears that Korean Ginseng has an excellent effect upon early phase of fracture healing of the bone. The summary of this study are as follows: 1. With near maximal dose, Korean Ginseng showed very excellent effect upon early phase of the fracture healing. 2. There was no apparent effect on remodeling phase of the fracture healing with Korean Ginseng of near maximal dose. 3. Korean Ginseng appeared to have no effect on fracture healing with minimal dose. 4. Upon biomechanical properties of the bone, Korean Ginseng was seemed to be effective with near maximal dose. But, there was no definite evidence for that.
