Wedge Tibial Shaft Fractures Treated with Interlocking IM Nailing

PURPOSE: To investigate the bone union time of patients treated with interlocking intramedullary nailing in wedged tibial shaft fracture and to evaluate the factors that influence this result. MATERIALS AND METHODS: 32 patients treated with interlocking intramedullary nailing for wedge tibial shaft fracture were reviewed with a follow-up period of more than 1 year. Radiographic results were assessed with diameter (%) and length (mm) of wedge fragment, pre and postoperative displacement (mm) of wedge fragment. We also checked the bone union time of the main fragment and the wedge fragment (paired t-test). We investigated the bone union time acocording to the diameter, length of wedge fragment, pre and postopertvie displacement (correlation analysis). RESULTS: Bone union time of the main fragments averaged 15.3 weeks (6~53 weeks) and that of wedge fragment averaged 24.2 weeks (8~64 weeks) (p=0.005). There was no correspondence between wedge fragment diameter and bone union time (p=0.681), but the bone union time of wedge fragment increased in proportion to its diameter (r2=0.747, p=0.031). There was no correspondence between preoperative displacement of wedge fragment and bone union time (p=0.574), but the bone union time increased in proportion to postoperative displacement of wedge fragment (r2=0.730, p=0.001). CONCLUSION: Wedge fragments need longer time for bone union than main fragments in interlocking intramedullary nailing for wedge tibial shaft fractures. We need to pay attention to the displacemet of fragments in treating tibial shaft fractures with large wedge fragment.

Bipolar Hemiarthroplasty of Displaced Femoral Neck Fractures in Pakinsonism Patients

PURPOSE: To evaluate clinical outcome and functional result after cemented bipolar hemiarthroplasty of displaced neck fracture in parkinsonism patients. MATERIALS AND METHODS: 12 parkinsonism patients treated by cemented bipolar hemiarthroplasty of displaced femur neck fracture from August 1994 to October 2002 were evaluated. Posterolateral approach was performed. Preoperative and postoperative walking ability, activity of daily life and severity of parkinsonism were compared. The effects of parkinsonism on clinical outcome were analyzed retrospectively. RESULTS: The median difference of walking ability was 1 (p=0.001) and that of ADL scale was -3 (p=0.0005). There was no significant change in the severity of parkinsonism (p=0.5), and the severity and duration of parkinsonism were not correlated with postoperative functional status. 7 cases of voiding difficulty, 5 of temporary delirium, and 2 of temporary respiratory insufficiency were noted as general complications. 2 cases of dislocation and 1 of infection were noted as orthopaedic complications. CONCLUSION: In parkinsonism patient, walking ability was worsened, activity was more independent, but severity of parkinsonism was not changed after hemiarthroplasty of displaced femur neck fracture. Orthopaedic surgeons should bear in mind that functional outcome is poor and orthopaedic complication rate high in parkinsonism.

Comparison between X-ray and Three Dimensional Computed Tomography in Trimalleolar Ankle Fractures

PURPOSE: To evaluate the accuracy of X-ray evaluation in classification, displacement and size of posterior malleolar fragment, comparing with three dimensional computed tomography (3D CT) in trimallelar ankle fractures. MATERIALS AND METHODS: 20 cases of trimalleolar ankle fractures evaluated with preoperative 3D CT, and followed up periods were at least 2 years. All cases were classified according to the Danis-Weber and Lauge-Hansen classification. Displacement and size of posterior malleolar fragment were measured using PACS. The reliability between simple X-ray and 3D CT was evaluated in the Danis-Weber and Lauge-Hansen classification (kappa analysis). The correlation between simple X-ray and 3D CT was evaluated in displacement and size of posterior malleolar fragment (correlation analysis). RESULTS: Degree of agreement of Danis-Weber classification in simple X-ray and 3D CT was 0.700 kappa value, and that of Lauge-Hansen was 0.605 kappa value. Measurement of simple X-ray and 3D CT about displaced status of posterior malleolar fragment showed statistically significant positive linear correlation (p= 0.000), but correlation of measurement of size in simple X-ray and CT was not statistically significant (p=0.102). CONCLUSION: CT or operative field will be more accurate than simple X-ray to select the method of treatment and operation, especially when the displacement and size of posterior malleolar fragment are important to decide.

Superior Gluteal Artery Pseudoaneurysm without Pelvic Bone Fracture: A Case Report

Pseudoaneurysm is defined as the aneurysmal cyst resulted from partial or total rupture of vessel membrane, and it can be caused by fracture, operation, laceration, blunt trauma, osteochondroma and so on. When the displaced pelvic bone fracture is diagnosed, the traumatic pseudoaneurysm, which is frequently related by the direct injury of vessel, is one of the common complications, and it can result the massive hemorrhage even death. In case of the displaced pelvic bone fracture, surgeon should check the hemoglobin level and vital sign carefully for the possibility of vascular injury. Authors report the rare case of superior gluteal artery pseudoaneurysm without pelvic bone fractrure.

Study on Circulating Factor(s) in Patient with Recurrent Focal Segmental Glomerulosclerosis / 대한신장학회잡지

BACKGROUND: Although a significant number of studies were done on focal segmental glomerulosclerosis(FSGS), its pathogenesis has not been sufficiently established yet. Recent studies suggested certain types of circulating factor(s) played an important role in development and recurrence after renal transplantation of FSGS by modifying the glomerular permeability of albumin. The purpose of this study performed on animals and through molecular-biological experiments is to certify the role of circulating factor (s), which cause proteinuria, by manipulating plasma of a FSGS patient who showed massive of proteinuria and wide effacement of glomerular epithelial foot processes in histologic examination after renal transplantation. also, whose massive proteinuria decreased significantly after plasma exchange. METHODS: The patient's plasma prior to(plasma A) or post to(plasma B) plasma exchange were injected into tail veins of two groups of male Sprague-Dawley rats, six in each. The ratio of 24 hour urine protein and urine creatinine(Uprt/Ucr) was calculated for each case. The 2D gel electrophoresis was performed in plasma A and plasma B. The pattern of 2D gel electrophoresis of plasma A was compared to those of plasma B and healthy human serum. RESULTS: Compared to control group, there was no significant differences in 24-hour Uprt/Ucr afer injecting 1, 2, 3, 5 mL of plasma A(p>0.05). There was no significant difference in 24-hour Uprt/Ucr between the injecting groups of plasma A and plasma B(p>0.05). We were not able to observe any new protein which did not appear in plasma B or healthy human serum in 2D gel electrophoresis. CONCLUSION: These results suggest that the proteinuria developed in a few hours after renal transplantation and is related to wide effacement of glomerular epithelial foot processes, and that it may be induced by a certain factor which is eliminated by the plasma exchange or restrained by the immunosuppressive agents. However, we were not able to find certain circulating factor(s) which rapidly changes albumin permeability in the patient's plasma with FSGS.

The Study of Pathologic Difference between Endoscopic Biopsy before EMR and Histology of Specimen after Endoscopic Mucosal Resection (EMR) on Gastric Flat Adenoma or Early Gastric Cancer (EGC) / 대한소화기내시경학회지

BACKGROUND/AIMS: It is not uncommon to show discrepancy between the histology of the endoscopic biopsy and that of the resected specimen obtained from the same lesion by EMR. The aim of this study was to ascertain whether routine endoscopic biopsy specimens are sufficient to qualify the representative enough to reliable indication of EMR. METHODS: We retrospectively reviewed 36 cases that could be compared the histologic results from the resected specimens by EMR to the tissue obtained by endoscopic biopsy. The histologic slides were reviewed by one pathologist. RESULTS: Of the 36 cases, 13 cases of EGC and 23 cases of gastric flat adenomas were included. Among 13 cases of EGC, 2 case (15.4%) revealed discrepancy between the histology of the endoscopic biopsy and that of a resected specimen by EMR. The histology of a resected specimen by EMR revealed moderate differentiated adenocarcinoma, while that of endoscopic biopsy was a well differentiated adenocarcinoma. Gastric flat adenoma revealed 47.8% (11/23) of discrepancy. CONCLUSIONS: The histologic discrepancy between the result of endoscopic biopsy and that of the resected specimen obtained by EMR was about 8% in EGC and 47.8% in gastric flat adenoma.

Coronary Arteriography in Acute Transmural Myocardial Infarction

To delineate the coronary anatomy and left ventricular function during early myocardial infarction, coronary arteriography and left ventriculogrphy were performed, prospectively in 23(22%) of 105 patients who were admitted to the coronary care unit at Masan Koryo Hospital from June 1986 to June 1988 within 4 weeks after the onset of symptoms(medium:21 days, range:18 days to 25 days). 1) Among 23 patients, male is 20 patients and female is 3 patients. The ratio of male to female was 6.6:1. The mean age was 55.4+/-10.3 years(range:34-77 years). 2) Coronary artery narrowing state which related to myocardial infarction was as follows; 2 patients(7%) had normal, 1 patients(4%) had insignificant narrowing(below 50%) 5 patients(22%) had moderate narrowing(50-75%), 10 patients(43%) had severe narrowing(75-99%), 5 patients(22%) had complete occlusion(100%). 3) The range of coronary artery disease was as follows; 9 patients had one vessel disease, 10 patients had two vessel disease, 1 patients had three vessel disease, and ejection fraction had no significant difference among 3 groups but lowest in three vessel disease. Among 23 patients, 13 patients had anterior infarction, 10 patients had inferior infarction. 4) Left ventricular ejection fraction and multiple vessel disease had no significant difference between i) the young(under 45 years old) and the old(over 45 years old) age groups, ii) presence or non presence of previous angina, iii) Killip classification I, II and III, IV) anterior infarction and inferior infarction. 5) In left ventriculography, akinesis and dyskinesis were shown at similar ratio in anterior infarction and inferior infaraction. Dyskinesis was shown in 27% of patients who have 0-1 vessel disease, 50% of patients who have 2-3 vessel disease, 62% of patients who have collateral circulation, 26% of patients who dose not have collateral circulation. 6) Collateral circulation was found in 8 patients(35%). Age and left ventricular ejection fraction were high in patients without collateral circulation than with collateral circulation, but there is no significant difference and collateral circulation exists regardless of infarction site and range of coronary artery disease. 7) As for the complication of angiocardiography in this study, there was ventricular tachycardia in 3 patients(13%) without mortality. It is concluded that coronary arteriography can be safely performed in early stage after acute myocardial infarction. Also good prognosis is anticipated since three vessel disease and complete occlusion were low in acute myocardiaol infarction of Korean People. Since these are not much case performed study, however more study on this area is required.
