Fracture of the coracoid process are rare and those associating with a complete acromioclavlcular separation is even more rare. The mechanism of injury may be attributed to either direct or indirect trauma. Most coracoid fractures are minimally displaced because It is by maintained by the coracoclavicular ligament and coracoacromial ligaments. Usually good result is obtained In the coracoid fracture by non-operative treatment. On the other hand open reduction Is rarely Indicated. The case we are reporting was treated by open reduction and Internal fixation of the acromloclavicular joint using two Kirschner wires, and screw fixation was done for the fracture of the base of the coracoid process. Review of the literature ls also done.

The present study is an observation of 678 cases of children's fractures; which was treated in the Dept. of Orthopedic Surgery, inchon Christian Hospital, for the past ten years, from 1968 to 1978. The peak age was in from 5 years to 6 years. The sex ratio was 2.9 male to 1 female. The ratio between the right and left extremity was nearly equal. The frequency of fracture of the upper extermity was silghtly dominant then lower extremity. The cause of fracture was fall down Injury in nealy 70% of all cases. The epiphyseal Injury was noted as 16.8% of total orthapedic cases. The most common type of Salter & Harris Classiflcation was type II or 56.1%. Mostly all of children's fractures were treated by closed method, and others were treated by open reduction. Complication Included 29 cases of changed carring angle 18 cases of traumatic arthritis and 8 cases of malunlted supracondylar fracture and 3 cases of postoperative Infections and 2 cases of radial nerve palsy and 3 cases of delayed ulnar nerve palsy of the elbow. In fractures of the femur, 3 cases of the peroneal nerve palsy and 2 cases of leg longth discrepancy was noted. Brief discussion and review of Iiterature is presented.

PURPOSE: To determine the necessity of site-specific bone mineral density(BMD) measurement and the difference between the BMD of the two femora using DXA in the evaluation of osteoporosis. MATERIALS & METHODS: Total BMD and regional BMD(Lumbar spine, femoral neck, Ward's area, intertrochanter area) were measured on seventy-eight healthy persons without previons diseases, and the statistical significance analyzed. RESULTS: Total BMD did not reliably reflect the site-specific BMD. There was a high correlation between BMD in opposing femora. Correlation coefficients between the femoral neck, Ward's area, trochanter area were 0. 939, 0.874 and 0.916 respectively. CONCLUSION: We conclude that a measuremnt of site-specific BMD is necessory because the total BMD can not reliably predict the regional BMD. The measurement of BMD in one femur can predict the BMD of the contralateral femur. If there is no history of femoral neck disease, unilateral BMD measurement is recommended for femoral evaluation.

EDAP-LT01 ESWL underwent 71 treatments in 20 patients with urinary stone of solitary kidney between February 25, 1987 and August 18, 1988. 1. The sex ratio was about 2:1, 13(65.0%) in male and 7(35.0%) in female patients. The average patient age was 50 years with a range of 23 to 65 years. The previous nephrectomy was owing to urinary tract stone in 19(95.0% ) and transitional cell carcinoma of renal pelvis in 1 (5.0%). 2. The duration of hospitalization was required from 2 to 7 days and the average post-ESWL stay was 1.5 days. 3. The treated stone locations were kidney in 18(90.0% ) ;calyx in 12(60.0% ) and renal pelvis in 6(30.0%) and ureter in 2(10.0%) ;upper ureter in 1(5.0% ) and lower ureter in 1(5.0%) There were multiple renal stones in 4(20.0% ).The average stone size was 1.6cm with a range of 0.7 to 4.1cm. 4. The average numbers of treatrnent were 2.7 sessions and the average treatment time was 30.2 minutes with a range of 17 to 42 minutes. The average storage was required 180 in one session. Of the patients, 4(20.0% ) were complained severe pain but treatment interruption or anesthesia were not required. 5. The success rate among 11 patients who completed ESWL treatment were 100.0% in 0.7-1.0cm, 60.0% in 1.0-2.0cm, 100.0% in 2.0-3.0cm and 77.8% in calyceal stones, 100.0% in renal pelvis stones. 100.0% in lower ureteral stones. Thus, the total average success rate was 81.8 %. 6. The method of pre-ESWL additional manipulation was used a upper ureteral stone 'push-up' in 1(5.0%). The post-ESWL additional measures were made in 4(20.0 % ) ;'push-up' & double -J stenting in 1(5.0% ) and double-J stenting in 3(15.0% ). The causes of failed ESWL were impacted stone in 1 and 'push-up' failure in 1. 7. None of the patients had significant changes in renal function by shock waves. ESWL complications were not required admission and medical management. Therefore, we confirmed that EDAP-LTOI piezoelectric ESWL is not influenced on renal function and is a safe, effective method for treatment of urinary stones in patients with a solitary kidney.

Korean Journal of Urology 1991;32(6):941-949
From February 1987 to December 1990, 654 patients with renal stones completed the multiple ESWL monotherapies using the EDAP-LT01 piezoelectric lithotriptor. The location of stones was calyx in 452 patients. pelvis in 1O8. calyx and pelvis in 94 and the stone size ranged from 0.6 to 4.8cm (mean 1.9cm). The number of treatment sessions was 2 to 19 sessions (mean 4.7) with 72.2% of re-treatment rate. In accordance with increment of stone size, number of treatment increased but success rate decreased; 2.8 sessions. 96.2% for 0.6-<1 cm. 4.4, 93.2% for 1-<2 cm, 5.5. 87.7% for 2-<3 cm. 6.3, 65.5% for 3-<4 cm and 6.4, 58.8% for stones larger than 4 cm. Supposing 654 patients had been completed by 5 sessions only. 67.9% of success rate would have been expected. But. 88.4% (578,654) of success rate was obtained by multiple treatment up to 19 sessions, adding 20.5%. Auxiliary ureteral manipulations were required in 88 (13.5%) patients and there were no significant complications. Therefore. multiple ESWL monotherapy is considered to be a efficient. safe procedure as the first applicable method for treatment of larger renal stones and to extend the indications of ESWL for renal stone.

8.Dynamic infusion cavernosometry and cavernosography(DICC).
Korean Journal of Urology 1991;32(4):649-656
During the last several years, cavernosography has been commonly used to demonstrate the hemodynemic abnormality of the corpora cavernosa. But this was recognized as a less obvious, physiologic and objective study. Recently a more ideal method has been introduced and resulted in the development of the procedure entitle Dynamic Infusion Cavernosometry and Cavernosography ( DICC). The DICC is done in four phase :phase I involves the determination of equilibrium corporeal body pressure and time required to reach the plateau. Phase S involves the determination of the rate of fall of corporal body pressure from a control pressure (150mmHg) over a defined observation period (30 seconds). Phase III involves the determination of cavernosal arterial systolic occlusion pressure and finally phase IV involves the cavernosography at a predetermined corporael body pressure (90mmHg). Now, this procedure is performed as the first invasive erectile function test in those individuals considered for vascular reconstruction of their erectile problem.

A total of 14 children underwent 29 treatments with EDAP-LT01 extracorporeal shock wave lithotripsy for urinary tract stones between February, 1987 and ugust, 1988. The results were obtained as follows : 1. The sex ratio was about A 2:1, 9 (64.3%) in male and 5 (35.7%) in female patients. The average patient age was 7.1 years with a range of 2 to 16 years. 2. Treated stone locations were kidney in 8 children (57.1% ) ; calyx in 6 (42.8% ) and renal pelvis in 2 (14.3% ) and ureter in 6 (42.9% ) ; upper ureter in 2 (14.3% ) and lower ureter in 4 (28.6 %). There were multiple renal stone in 4 (28.6% ) and bilateral renal stone in 1 (7.1%), the average stone size was 1.6cm with a range of 0.7 to 3.1cm. 3. The average numbers of treatment were 1.8 sessions and the average treatment time was 38.7 minutes. The average storage required was 107 in one session. 4. Of the 11 patients whose age was less than 10 years, 10 (71.4% ) required caudal anesthesia. Three patients whose age was more than 10 years treated without any type of anesthesia. 5. The total average success rate of treatment-ended 11 patients was 81.8% in stones of 0.7-3.0cm. The cause of failed ESWL were stone component in 1 and impacted stone in 1. 6. All or the patients were not required the pre and post-ESWL additional manipulation. ESWL complications were not required admission and surgical management. Therefore, we confirmed that EDAP-LT01 ESWL is a safe, effective and easily applicable technique for treatment of urinary stones in children.
