Evidence in human studies of the association of long term habitual exercise with bone mineral content (BMC) and bone mineral density (BMD) mostly come from studies done on athletes. The highest BMC and BMD values in young adults have been found in strength and power-training athletes, while endurance activities such as long distance running and swimming seem to be less effective in obtaining peak bone mineral density. To compare the differences in BMD among ballet, Korean traditional dancing and athletics, we examined the BMD of 10 ballerinas, 10 Korean traditional dancers, 12 athletes and 12 volunteers as the control group. All participants were female. The average age were 20.6 years for the ballerinas, 21.2 for the Korean traditional dancers, 20.4 for the athletes and 21.3 for the control group. Average weights were 50.6 kg for the ballerina, 53.7 kg for the Korean traditional dancer, 59.2 kg for the athletes and 53.8 kg for the control group. Average heights were 162.0 cm for the ballerinas, 160.4 cm for the Korean traditional dancers, 162.3 cm for the athletes and 160.5 cm for the control group. There were no significant differences in the BMD values of the proximal femur and the lumbar spine between ballerinas and control group and between Korean traditional dancers and control group (p>0.05). There was, however, a significant increase of BMD in the proximal femur and lumbar spine of the athletes when compared with the control group (p<0.05) After adjusting for difference in body mass index (BMI) we recompared the BMD of ballerinas, Korean traditional dancer and athletes with BMD of control group and found significant higher lumbar spine BMD values in ballerinas, Korean traditional dancers and athletes. In athletes higher BMD levels were also obtained in the proximal femur including the neck, greater trochanter and Wards triangle regions (p<0.05). There was no significant increase of proximal femur BMD levels for Korean traditional dancers (p>0.05). Differences of BMD values between the ballerinas and control group was statistically significant only in femoral neck (p<0.05).

Distal renal tubular acidosis (RTA) is a biochemical syndrome as a deficiency of hydrogen in secretion by the distal tubule and collecting duct. Owing to the nature of the defect, hyperchloremic non-anion gap metabolic acidosis and high urine pH despite severe systemic acidosis is characterized. Typical manifestations of distal RTA are growth retardation, rickets, polyuria and nephrocalcinosis. We experienced a case of distal renal tubular acidosis in a 4 years old female child who complained of growth retardation and gait disturbance. She showed typical hyperchloremic non-anion gap metabolic acidosis and persistent high urine pH. In radiographic examination. we found delayed bone age and severe rachitic changes of wrist, elbow, and knee as well as nephrocalcinosis. In ammonium chloride loading test, high urine pH persisted despite the lowering blood HCO3- concentration. After alkali therapy, she is in well condition with excellent growth velocity and absence of rachitic changes.

The flexor tendon injuries of the finger are very difficult to treat satisfactorily. Early treatment is desirable, but not always posaible. In addition, joint stiffness and limitation in gliding of the tendon caused by adhesion, make the problem more complex. From 1978 until 1988, 13 patients (14 eases) underwent operations for free tendon graft, and 10 patients (13 eases) for staged tendon graft at the Department of Orthopaedic Surgery, National Medieal Center. They have been followed up for clinical study, and the result was summarized as follows:1. Old flexor tendon injuries were common in the teen and twenties, especially in male. 2. They occurred in the index (10 Cases, 37.0%) and middle (8 cases, 29.6%) fingers most commony, especially zone II (62.9%). 3. The result was evalusted according to the method designed by Strickland and Glovac. In 19 out of 27 cases, satisfactory result (excellent and good) was yielded. 4. In cause, deep laceration by sharp object was better in the result than crushing injury. 5. The interval between the injury and the operation ranged from 1 month through 11 years, averaging 16 months, and is supposed to have little relation to the result. 6. The preoperative state is supposed to have much relation to postoperative result, judging from 100% of satisfactory result in Grade I compared with 40% in Grade V according to Boyes preoperative classification. 7. Little difference is seen in the result between free tendon graft and staged tendon graft. And 5 cases complicated by adhesion, rupture of grafted tendon and wound infection yielded poor result.

Total hip arthroplasty(THA) is applied to various hip diseases, and the results are different according to the disease entities. We have made the functional evaluation of three groups of the patients who had undergone THA in Seoul National University Hospital from 1981 to 1990: the first group-fused hips (28 hips of 27 patients), the second group partially ankylotic hips whose total range of motion were less than 60°(46 hips of 46 patients), and the third group-hips of ankylosing spondylitis (22 hips of 14 patients). The results were summerized as follows: No statistically significant difference was seen in the postoperative average Harris hip score between three groups. In the postoperative average range of motion, statistically significant difference was seen only between the first and second groups. Therefore, similar clinical results can be obtained from the THA in the fused hips to those of the partially ankylotic hips such as tuberculous or septic hip sequelae.
