Forearm bone fractures are difficult to manage, because of their special functions (pronation and supination) and peculiar anatomy. Authors have experienced 68 cases of various types of forearm bone fractures from January, 1968 to December, 1971. They were analized as following. 1. Out of 68 patients, males were 54 cases (79.4%) and females were 14 cases (30.6%). Among them, 91.2% of the cases were occured in people over 15 years old. About 47% of the cases were caused by automobile accidents. 2. Both forearm bone fractures were 51 cases (75%), and most common site of the fractures were mid 1/3(66.2%). Stable (transverse or incomplete) fractures were 24%, and unstable(comminuted, segmental, oblique or spiral) fractures were 76%. Open fractures were 26.5% 3. Conservative treatment was given to 41 cases (60.3%), and open reduction & internal fixation was given to 27 cases (39%). 4. A comparison has been made between the groups treated by conservative method and open reduction & internal fixation. 1) Average healing time of open reduction group was 19.5 weeks and conservative group was 16.4 weeks. 2) Non-union was occured in 7.4% of conservative treatment group, and 22.7% of open reduction group. 3) Satisfactory functional results were shown in 23.5% of conservative group and 54.5% of open reduction & internal fixation group. 4) Rotational deformities were noticed in 53.3% of the conservative treatment group and 54.5% of the open reduction group (No difference was noticed). 5) Angulatory deformities were shown in 70.4% of the conservative treatment group and 44.4% of the open reduction group. 5. Three cases were complicated by cross unoin, and no postoperative wound infection was noted. But two cases of open fracture developed to chronic osteomyelitis.

Forty one cases of patella fractures which were treated at the Department of Orthopaedic Surgery, Catholic Medical College during the period from January 1971 to March 1974 were presented. Most fractures encountered in man of 3rd and 4th decades, sixty percent of fracture was in the mid-pole of patella and thirty percent in the lower pole. Twenty nine(29%) fracture was induced by direct blow and remainders by indirect violence. When the knee joint was immobilized in 15 flexion with crlinder cast in certain period of time, early joint mobility was restored after the discontinuence of the cast. The tibial tubercle-plasty in association with fracture reduction to increase quadriceps power and to prevent late occureace of patellofemoral arthritis gave satisfactory result in two cases.

Nowadays the clinical impression in Korea is that genu varum uncommon though there was high incidence of this deformity by vitamin D deficiency in the early 1900. Authors reviewed the case histories and x-ray of 18 patients treated for this condition at the Dept. of Orthopaedics, St. Mary's hospital for past 5 years: 17 patients were under 5 years of age. 12 patients had rachitic bowIeg and among them four had active ricket. Six patients had physiologic bowleg deformity. Classification in four grades according to severity of bowleg is attempted. Among the cases eleven patients having less than 10 degree of bowleg treated conservatively with good end result, but corrective osteotomy is routinely scheduled for seven patients having bowleg of knee over 10 degree and resist to treatment. Lasting it is stressed that physiologic bowleg shoud be distinguished from pathologic one. Diagnosis of bow leg can not be made before age of 2–3 years, that is, before transitional phase of development of knee angle.

Calcaneal fractures of 82 feets in 68 patients which were treated at the Dept. of Orthopedic Surgery, St. Mary's Hospital since 1974 to 1978 were cllnically analysed, and the following results were obtained. 1. Of 68 patient 50 patients were male and 18 female. Their ages ranged from 9 to 58 years and averaged 33 years. 2. Fourteen patients had both calcaneal fractures, and the spine fractures were associated in 14 patients with calcaneal fractures. 3. Of 82 fractures 50 fractures were Rowe's type 5. Of these type 5 fracture 14 cases of tongue type were treated by axial pin flxation and favourable result were obtained. All the other types of fractures were treated conservatively. 4. After treatment, the most common complication after treatment was presistant foot pain. The commonest site of residual pain was beneath the lateral malleculus. Of 82 fractures 22 cases had this complaint. This residual pain occured in the seventeen cases type 5 fracture. 5. Residual flat foot deformity and weakness of triceps power were clinically not significant if the residual foot pain is nat associated with those two factors.

Authors had reviewed the results of 20 anterior cervical fusions performed between 1975 and 1980 to determine which factors were important to a successful result. There had been 18 single level fusions and 2 fusions at two levels, the majority at C and C. The indications for fusion operation were: firstly in acutely traumatized patient was the spine representing radiologically the signs of segmental instability, secondly was the chronic segmental instability in old traumatized spine representing the nuchal rigidity and severe cervicobrachial pain which. was not ceased by conservative treatments. The index of successful fusion was complete relief of pain, loss of cervical rigidity and radiologlcal stability of fused segment indicated by no-movement in flexion-extension lateral radiograms, and the bony bridges between the fused segments. The postoperative stability of spine was assessed by measuring the changes of disc space and kyphotic angle. The result obtained were as follows: 1. Pre-and post-operative immobilization with cervical traction played an immportant role for successful results after fusion: 4–6 weeks of pre-operative traction in acutely injured spine provided the torn soft tissue structures with sufficient time needed for its healing, and 6 weeks of postoperative traction also provided the bone graft with sufficient time needed for its cooperation with graft bed. 2. ln all cases succeasful fusion was obtained. In a case a adjacent level was incorrectly fused, but it was fused soundly in time, while the unstable unfused segment was not fused spontaneously. 3. The fused segment or segments of spine stabilized clinically in 6-8 weeks after fusion operation which was proven by serial radiograms, and solid bony fusion was obtained radiologically averaging in 12 weeks after fusion operation. 4. The average increase of kyphosis after interbody fusion till solid fusion was negligible, averaging 3.0 degrees. 5. The solid fusion occurred in one to 2 weeks earlier in the spines with wedge and axial conpression fractures than the spines with flexion-rotation and shear types of fractures. 6. No further neurogical damage developed after successful fusion.

Authors clinically analysed the end results of the 56 elderly patients having fresh femoral neck fracture who were treated with osteosynthesis procedures and 23 endoprosthesis replacement surgery. All these 79 patients were treated between 1970 and 1979 at the St. Marys Hospital, Seoul. The indications of primary endoprosthesis replacement surgery in femoral neck fractured patients were in elderly patients over 65 years, displaced, comminuted sub capital or transcervical fractures, irreducible fractures, pathological fractures and patients having generalized diseases or senile psychosis. The results for the operated hip joints were assessed by duration of hospitalization, early and late post-operative complication. and the Jessels hip grading method at least post-operative one and half year later. The results obtained were as follows: 1. The average age of the patients were 65 years in 56 cases with initial osteosynthetic group, and 73 years in 23 cases of initial endoprosthesis group. 2. The slip down was the most common cause of injuries. The transcervical type of fracture was 54% of all cases. 3. The eligibility of ambulation was average 34 days after surgery in cases having initial osteosynthesis and 18 days in cases having endoprosthesis. 4. Early post-operative complications such as pneumonia and urethritis etc. were more common in cases of endoprosthesis than in osteosynthesis. But we think these complications were not related with surgery itself and transient. 5. Late post-operative complications in cases of osteosynthesis were avascular necrosis of head (16%), nonunion (9%), osteoarthritis (4%), and deep wound infection (2%), but in cases with endoprosthesis, leg length discrepancy (12%), acetabular erosion (4%) and loosening (4%) in order. 6. We performed the second operation in 12 cases among the 56 patients of osteosynthesis because of post-operative complications. 7. Good end results were obtained 90% in 56 osteosynthesis and 91% in 23 endoprosthesis. Conclusively, author's observation time was relatively short (11/2–3 years) and it is impressed that long term study for the prosthetic group is necessary for the more accurate evaluation of their hip function.

Synovial sarcoma is a highly malignant tumor which arises from synovial tissue derived from mesothelium and its occurrence is very rare. Furthermore, congenital synovial sarcoma which developed from aggressive deposition of tumor cells during intra-uterine fetal life is extremely rare. Authors present a case of congenital synovial sarcoma which is found in the right ankle of one month old boy, because of its rarity of occurrence.

9.Pulse Transmission Times in Hyperthyroidism.
Korean Circulation Journal 1977;7(1):23-32
The pulse transmission times measured from polygraphic recordings of cardiac events were studied in 52 cases of female hyperthyroidism and 60 cases of normal females. The pulse transmission times measured in this study were M1-S, R-S and C-S intervals, i.e., the time intervals from the mitral first sound, the R wave of an electrocardiogram and the onset of the upstroke of the ventricular contraction in an apexcariogram to the finger tip, respectively, and the A2-C interval, and interval from the aortic second sound to the finer tip. The M1-S, R-S and C-S intervals, which were measured during systole, were significantly shortened in proportion to the severity of the disease, whereas the A2-C interval, which was a measurement during diastole, was well within normal limits. By correcting these observed values for the heart rate, the A2-C interval became significantly longer than in the control, apparently in proportion ot the severity of the disease. The M1-S, R-S and C-S intervals, however, were normalized by the correction. In the analysis of the correlation of these observed values to the age and the various hemodynamic parameters, it was noted that the A2-C interval was negatively correlated to the diastolic and mean blood pressure, which tended to be low in this condition, and was positively correlated to the age, but had no correlation to the heart rate or the systolic blood pressure. The A2-C interval also showed positive and negative correlation to left ventricular ejection time/isovolumic contraction time ratio and preejection period/left ventricular ejection time ratio, respectively. On the contrary, there was a tendency for the remaining intervals measured during systolic to be negatively correlated to the systolic blood pressure, which tended to be high, heart rate and age, as well as systolic time intervals. These facts suggested that the shortening of the M1-S, R-S and C-S intervals was caused primarily by the rapid heart rate and also by the systolic hypertension. It was strongly felt that the A2-C interval was of a limited value as an index of the pulse transmission in hyperthyroidism.

10.Healing of the Bony Gap with Periosteal Osteogenesis After Tibial Diaphysectomy in Adult: Report of A Case
Myung Sang MOON ; Choong Heung KIM
The Journal of the Korean Orthopaedic Association 1971;6(1):75-78
The diaphysectomy of a large tubular bone is occasionally done as a method of treating chronic osteomyelitis. Obliteration of the bony gap with stable complete reunion by periosteal new bone formation is rare in adult and is usually not expected to be complete. Therefore, the bony defect generally is replaced or refilled to bridge the gap by massive bone graft after complete subsidence of the inflammatory signs, The authors report a case of chronic osteomyelitis of tibial shaft which was treated by diaphysectomy and healed with complete and stable periosteal new bone formation in the gap of diaphysectomized tibia without graft or replacement in a healthy young adult.
