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.

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.

Histological findings in corpus cavernosum were retrospectively evaluated in 36 patients with erectile impotence. Biopsies were obtained during insertion of penile prosthesis from both corpora. The most prominent histological findings were fibrosis(63.9%) and hyalinization(50%). Peyronie`s disease was not clinically diagnosed in any patient. Our findings suggest that clinical penile cavernosal fibrosis is common and may be a significant etiologital factor in patients with erectile impotence.

9.Diagnostic Value of Intracavernous papaverine-Induced Artificial Erection.
Korean Journal of Urology 1988;29(4):579-587
To determine whether intracavernous injection of papaverine can discriminate vascular versus psychogenic impotence 40mg papaverine were injected intracorporally into 203 importens. And the diagnostic usefulness of intracavernous papaverine-induced artificial erection was compared with Snap Gauge test, penile brachial index(PBI), internal pudendal angiography and cavernosography. The results obtained were as follows ; 1. Among the 119 psychogenic impotent patients, 104(87.4%) showed full rigid erection and 1(0.8%) soft or absent erection at 5 minutes after injection, and 88(73.8%) full rigid erection and 2(1.7%) soft or absent erection at 30 minutes after injection. Among 33 patients with arteriogenic impotence none showed full rigid erection and 20(60.6%) soft or absent erection at 30 minutes. Among 12 patients with venous leak only one(8.3 %) showed full erection at 5 minutes, and none fully rigid erection and 7(58.3%) soft or absent erection at 30 minutes. 2. Of the 78 patients with an abnormal Snap Gauge test, the response papaverine injection was absent in 37(47.4%) and fully rigid erection in 11(14.1%). Of the 105 patients with a normal Snap Gauge test the response was full erection in 89(84.7%) and absent in 2(1.9%). 3. Among 17 patients of PBI < 0.75, 14(82.4%) showed soft or full erection and one(5.9%) full erection with papaverine injection. Among 186 patients of PBI >=0.75, 26(13.9%) showed soft or absent erection and 113(60.7%) full erection with papaverine injection. 4. Among 27 patients with severe arterial lesion on arteriogram, the response to papaverine injection was absent in 18(66.7%) and full erection in one(3.7%). Among 20 patients with severe venous leak on cavernosogram the response to papaverine injection was absent in 12(60.6%) and full erection in one(5.0%). Therefore, we conclude intracavernous papaverine-induced artificial erection is the best valuable test for differentialdiagnosis of psychogenic and vasculogenic impotence.

10.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.
