Osteoporosis is a disease characterized by excessive bone loss or osteopenia particulary in the axial skeleton at the site of fracture, such as the spine and proximal femur. Since the strength of both spine and femur is directly proportional to the bone mass, this osteoporosis always increases the risk of fracture. In this study, to evaluate whether a simple measurement of femoral geometry and BMD value are related with hip fracture, we obtained DEXA Scan (Lunar Expert-XL) of hip by retrospective study. DEXA scan was measured on 70 control people and 17 hip fracture patients aged 50 or older. The result is I. The mean Ward BMD value of hip fracture group is significantly lower than control group (Hip fracture group: 0.52g/cm2, Control group: 0.67g/cm2 P=0.0001) 2. The mean L-spine BMD value of hip fracture group is significantly lower than control group (Hip fracture group: 0.81g/cm, Control group: 0.97g/cm2 P=0.0002) 3. The mean femur axis length of hip fracture group is longer than control group (Hip fracture group: 6.77g/cm2, Control group: 6.57g/cm2 P=0.006) As a conclusion, the measurement of BMD and hip axis length in DEXA scan is an effective method for screening the hip fracture risk patient and BMD value of femur, hip axis length and L- spine BMD value are strongly associated with hip fracture.

Pott's paraplegia has been frequently serious complication of tuberculous spondylitis, although antituberculous drugs have improved the prognosis and healing of the disease. There are much controvercy on treatement of Pott's paraplegia, which comprises immobilization with or without anterolateral antituberculous drugs, immobilization and early posterior arthrodesis, anterolatear decompression and radical anterior decompression with anterior spinal fusion. The method of anterior decompression and anterior interbody fusion which was introduced by Hdgson since 1956 has good reults. The author analyzed 27 consecutive cases of Pott's parsplegia operated at orthopedic departement, In Je Paik Hospital from May 1980 to August 1988. The results were as follows, 1. Number of cases in child was nine(33%), both sexes were similar. 2. Regions of spine involved were most common at thoracic spine(62%). Number of affected vertebrae was averaged 3.3 vertebrae. 3. There were nineteen early(70%) and eight late(30%) paraplegia. 4. There were two complete and twenty five incomplete paraplegia. 5. In operative finding, inflammatory products and sequestrated material was extrinsic factor in early in paraplegia. 6. The recovery of the paraplegia occur in twenty cases(74%) 7. The recovery of paraplegia after treatment was far better in type of early onset, type of incomplete paraplegia less than one year duration. 8. The radical anterior decompression and anterior interbody fusion was considered as recommendable method for remove of all pathologic foci, recovery of paraplegia and healing the tuberculosis with stability.

Giant cell tumor is a predominantly benign condition but often the tumor is locally aggressive and tends to have high rate of recurrence and it can evolve into a malignant tumor. Thus the lesions have a practically difficult therapeutic problem for the orthopaedic surgeon and any method of treatment has not been satisfied. Between March 1984 and March 1993, clinical observation was carried out on 22 cases of giant cell tumor of bone to analyse the recurrence rate and functional evaluation of the joint according to the treatment methods, pathological grade and cortical destruction. The mean follow-up time was 75. 2 months. The recurrence rate of the intralesional excision group was 54.5% and that of the wide excision group was 9%, There was no relationship between the pathologic grade and recurrence rate. There was no recurrent case in the grade I cortical destruction but almost all of recurrence was occurred in the grade I or II cortical destruction. The functional result of the giant cell tumor occurred around the knee joint was that the mean ratings in the intralesional excision group were 79% and in the wide excision group were 51%. In conclusion, to achieve better joint function and less recurrence rate, intralesional or marginal excision with heat using bone cement or with chemical cauterization using phenol and alcohol can be used for cases of radiological grade I or II, and wide excision for grade III.

Acral persistent papular mucinosis has been thought to be a distinct for of cutaneous mucinosis not associated with systemic diseases. It was recently classified as one of five subtypes of localized lichen mixedematosus. A 64-year-old man presented with a 15-year history of flesh-colored to translucent papules and a few round hypopigmented patches on his wrists, back of the hands, and distal forearms. Biopsy from the papular lesions revealed focal mucin accumulation in the upper reticular dermis. The clinical and histopathological features were consistent with acral persistent papular mucinosis.
