Most studies of limb lengthening have concentrated on the osteotomy. In the present study, the response of soft tissue (muscle, artery, nerve) to different length, rates or rhythms of distraction have been investigated to define the nature of any damage and to see whether new muscle is created. The purposes of the this study are to evaluate the optimum condition for soft tissue during limb lengthening and to study the effect of different rates & rhythms of tibial lengthening on the soft tissue in rabbits hy observing the changes of muscle, artery and nerve. We lengthened the right tihiae of fifty-four growing New Zealand white rabbits by callotasis. The left tibiae were used as control. The rabbits were divided into three different rates & rhythms groups: Group 1 (increments of 0.5mm /day, divided 2 times/day), Group II (increments of 0.5mm/day, divided 3 times/day), Group III (increments of 10mm/day, divided 2 times/day). Each Group was subdivided into three lengthening groups: 1 ( 10% lengthening), 2 (20% lengthening), 3 (30% lengthening). At the end of lengthening, histopathologic & histomorphometric studies were done on the medial heads of gastrocnemius muscles, the posterior tibial artery and the posterior tibial nerve. In the histopathological study, these were stained by hematoxylin eosin, PAS and observed by light microscopy. Electron microscopic examination was done in all samples. In light microscopic findings, the sum of scores of the following five suhjects, each counted from 0 to 3, were analysed for individual groups between the experimental side and the control by the Mann-Whitney test and the kruskal-Wallis test. The following conclusions were made hased on the above observations; 1. There was no significant difference between groups I, II and III, but there was a significant dif-ference between the 10%, 20% and 30% lengthening groups by histopathologic study. And the predominant responses of muscle to the lengthening were atrophy and endomysial fibrosis. 2. There was no change in the proportion of the muscle fiber types by histomophomeric study. 3.ln the initial phase, the muscle adaptation to the gradual lengthening was attained by sliding in Jess than 20% distraction but finally the muscle was regenerated by new muscle formation. 4. Major soft tissue complication to the gradual lengthening was induced by muscle. But arteries & nerves were well adapted to the gradual lengthening up to 30% Iengthening.

Hypokalemic familial periodic paralysis is one of the rare familial disease characterized by recurrent and transient attacks of weakness or paralysis of the somatic musculature. Also, this disease is usually inherited as an autosomal dominant trait in most cases. During an attack, the plasma potassium falls as a rasults of shift of potassium from the extracellular to the intracelluar compartment, but there is no loss of total potassium from the body. We have experienced hypokalemic familial periodic paralysis recently which affected 4 members in a family,and report this disorder.

Recently, the rates of various traffic accidents and industrial injuries accordlng to industrial progression were increased very much. In those injuries, open tibial shaft fractures were one of the most common ones of all long bones of the body. The authors have reviewed and analyzed 30 cases of the open tibial shaft fractures which were treated by pin and plaster method at our hospital from April 1976 to August 1979. The results were as follows: 1. Most of the fractures occurred in 20 and 30 age levels, average age was 34.4. Male 5 > female 1 in accident frequency. 2. The causes were traffic accident (67%), direct blow (17%), falling down from a height (13%), and mechanical trauma (3%) in order. 3. In location of fractures, Lt. 16 > Rt. 11 > both. 3; lower (47%), middle (33%), upper (20%), one thirds and comminuted (60%) > transvers (20%) > oblique (13%) > spiral (4%) > segmental fractures in frequency. 4. The associated injuries were fractures of fibulas (67%) > multiple skin damages (40%) > knee joint patella injuries... etc. Total of those injuries were 68.; One patient gained 2.26 kinds of those injuries simultaneously. 5. By classification of Ellis, minor severity (33%) > moderate one (40%) > major one fractures (27%). And according to results of pin and plaster treatment, bony union took roughly 11, 15, above 23 weeks respectively. 6. The summed contaminatlon and infection rate was below 20%, and cultured bacterias were E. Coli (50%) > staphylocci (33%) > pseudomonas (17%) and susceptabilities to penicillin were 60, 90, 25% respectively. 7. By classification of time interval from injury to apply pin and plaster method, early applied group (17 cases) showed bony union rate (7.6.4%), delayed one (11.7%), nonunion (5.8%), late group showed 50, 12.5, 6.3%, far late group showed 40, 40, 20% respectively. 8. Duration of the cast immobilization was 4–7 weeks and then it was changed by P. T. B. cast until about 4 monthes from injury, after it, vigorous P. T. was carried out. Good results were come in 80% (24 cases). 9. Pin and plaster method will be indicated in minor & moderate severity-fractures, but in major ones, it will be used as a preliminary stage operation.

Aneurysmal bone cyst is an uncommon tumor-like lesion of the bone containing distended vascular channels or cvities filled with blood. These cases, twenty-nine old female, eighteen years old male and female patients complained of pain and swelling in Rt. Medial aspect of proximal foot, Lt. proximal tibial portion and Rt. entire talar aspect of foot, respectively. Roentgenograms showed ballooned-out distensions and eccentric buldging of those lesions and soapbubble like multiple radiolucent cystic changes within interiors of the bones at talar neck, Proximal tibia and entire talus. Those cases were treated with radical curettage and autogenous iliac bone grafts and snugly fitted long leg casts in functional positions, respectively. On 2nd postoperative day, Cast windows were made and daily sterile dressings were carried out until complete wound healing. Pathological Examinations grossly and Microscopically revealed typical Aneruysmal bone cysts in all 3 cases. All-Patients had good therapeutic recovery within about seven weeks post-operatively.

Rheumatoid arthritis is a chronic inflammatory systemic disease of young or middle aged adults, characterized by destructive and proliferative changes in synovial membrane, periarticular structure, skeletal muscle and perineural sheaths. Eventually, joints are destroied, ankylosed and deformed. Moderate anemia is occured frequently in rheumatoid arthritis patients, and these patients show abnormalities of iron metabolism such as lower serum iron concentration and occurance and distribution of iron in the synovial membrane. It has been suggested that the mechanism of iron deposits in rheumatoid arthritis is continuous oozing of blood from vascular granulation tissue into the synovial cavity and this lead the patient to anemia. We collected samples from serum and knee joint fluid in 21 cases of rheumatoid arthritis for chemical estimation of the ferritin concentration by radioimmunoassay, and compared with that of osteoarthritis. The following results were obtained: 1. The mean hemoglobin concentration(11.4gm %) in rheumatoid arthritis was lower than osteoarthritis(13.4gm %). 2. The mean serum ferritin concentration(118. 4ng/ml) in rheumatoid arthritis was lower than osteoarthritis(135. 6ng/ml), on the contrary in synovial fluid rheumatoid arthritis(279.8ng/ml) showed higher than osteoarthritis(190. 4ng/ml). 3. The mean ratio of synovial fluid ferritin on serum ferritin was 2. 36 in rheumatoid arthritis, in contrast with l. 4 in osteoarthritis. There was significant correlation between the ferritin concentration in synovial fluid and serum. 4. Serial check of ferritin concentration in synovial fluid during treatment would be thought meaningful criteria for determination of progress.and effectiveness of treatment.
