In these days, there are two main ways in the treatment of the avascular necrosis of the femoral head in adult by prosthetic replscement; total hip replacement and bipolar endoprosthesis. So far, no study has been performed on the post-operative functional evaluation of them. Therefore it is difficult to decide which one is preferred to the other in the treatment of avascular necrosis of the femoral head in adult. In order to evaluate the functions of the prosthetic joints, the authors reviewed the results of 18 cases of cementless bipolar endoprosthesis(abbreviated as CBE) and 22 csses of cementless total hip replscement arthroplasty(abbreviated as CTHRA), performed at the Department of Orthopedic Surgery, Seoul National University Hospital, during the period from February, 1984 to May, 1986. The following results were obtained. 1. The average ages of CBE and CTHRA groups at the time of operation were 48.5 years and 37.5 years, respectively. 2. The average follow-ups of CBE and CTHRA were 15.7 months and 30.5 months, respectively. 3. By Meyer's modification of Marcus and Enneking classification, the sverage stages of CBE and CTHRA groups were 3.7 and 4.4 respectively. 4. According to Harris hip rating score system, Harris scores were increased as much as 30.5 in CBE group and 30.6 in CTHRA group. 5. In the aspects of functional improvement and relief of pain, the two groups showed no significant difference. However, the operation was essier, and the damage to the acetabular bone was less in CBE group. For these reasons, CBE was believed to be the preferred choice of treatment of avascular necrosis of femoral head in adult.

Typhlitis or neutropenic enterocolitis is a life-threatening, necrotizing process of the cecum whose incidence is increasing. Typhlitis presents as fever, abdominal pain, and diarrhea in neutropenic patients. As the incidence of typhlitis increases, emergency physicians must be aware of this rapidly progressive and potentially fatal disease. The definitive management of typhlitis is controversial. The most prudent course for the emergency physician is to initiate aggressive medical management early in the ED. We describe a 25-year-old man with severe neutropenia presented to the emergency department with fever, abdominal pain, diarrhea that began 2days earlier. Abdominal computerized tomography(CT) demonstrated diffuse concentric thickening of the cecal wall, intramural edema, inflammatory bowel changes but no free air and abscess formation. He was recovered by early diagnosis and aggressive medical therapy. We report a case of typhlitis with literature reviews.

Isolated infernal iliac artery aneurysms and rupture are relatively infrequent, often difficult to detect and therefore rarely considered in the differential diagnosis for abdominal pain. The consequences can be grave, The incidence of isolated iliac artery aneurysm is 1~2% of that of abdominal aortic aneurysm(AAA). The natural history is of gradual enlargement, with rupture the most common clinical presentation. The signs and symptoms of such an aneurysm are influenced by its concealed location within the bony pelvis. Awareness of these special characteristics improves the chances of early diagnosis and proper surgical treatment before possible rupture. Here is a case of ruptured aneurysm of left internal iliad artery. A 73-year-old man was presented to our emergency center with severe abdominal pain and voiding difficulty Abdominal Computed Tomography(Cf) and angiography showed ruptured aneurysm of left infernal iliad artery. Emergency operation was successfully performed for the ruptured internal iliad artery aneurysm.

In 1961, Salter had devised the innominate osteotomy in treating C.D.H, which has been one of the most popular methods in these days. 14 hips with 12 patients who have been admitted and received Salters innominate osteotomy in the department of orthopaedic surgery, National Medical Center, from Feb. 1974 to Dec. 1976, were evaluated as for the results. Clinical analysis and follow-up study were carried out in 14 hips with C.D.H. and the following results were obtained. The mean age of the cases was 34 months, and sex preponderance of female to male was 11: 1. The ratio of left to right was not significantly different. 2 cases of complication out of 12 cases was found; redislocation and subluxaiton respectively. The age of first detection of C.D.H., was surprisingly late around 18 months old. In addition, approximately 12 months has elapsed between the first detection of C.D.H. and the first consultation to doctor. Assesment of the result was carried out by Severine and Macays method respectively; Radiological evaluation was as followings: (Severine) Excellent: 4, Good: 8, Fair: 1, Poor: 1. Clineal evaluation was as followings: (Macay) Excellent: 4, Good: 7, Fair: 1, Poor; 1, Failure: 1.

BACKGROUND: To estimate real time concentration of drugs during TIVA is theoretical, but it is not easy and inefficient. To maintain designed target concentration with continuous infusion using methods that account for the multicompartmental pharmacokinetic profile of fentanyl, isoconcentration nomogram is one of the methods. We evaluated the clinical usefulness of the isoconcentration nomogram using two different expected concentration of fentanyl. METHODS: Thirty ASA class I or II adult patients scheduled for spine fusion were randomly allocated into two groups according to 1.5 or 3 ng/ml of expected fentanyl concentration. Using isoconcentration nomogram, fentanyl concentration was adjusted and the propofol concentration was fixed to 3.5 g/ml according to Prys-Roberts method. Vital signs were titrated using variable flow rate of propofol. Fentanyl and propofol were discontinued 15 min before the end of operation. And, IV-PCA using fentanyl were applicated for postoperative pain control. The dosage of propofol and fentanyl, recovery time of consciousness and orientation were checked. Also, first buttoning time and 24hr fentanyl dosage in IV-PCA were checked. RESULTS: Average flow rate of propofol used were 7.5 1.2 mg/kg/hr in group 1, 5.7 1.1 mg/kg/hr in group 2 which was significantly lower than group 1 (p<0.05). Spontaneous eye opening and recovery of orientation was delayed 1.8 times in group 2. First buttoning time and 24hr fentanyl requirement for postoperative pain control using IV-PCA was delayed by 2 and decreased 60% in group 2, respectively. CONCLUSIONS: Isoconcentration nomogram was useful tool to control the expected concentration of fentanyl during TIVA and postoperative pain control using fentanyl IV-PCA.

Supracondylar fracture is the most freqent injury of the elbow and frequently accompany complications in children. This injuries require meticulous care during first week period for the prevention of complications. Sixty cases of supracondylar fracture in children treated and managed at the Orthopedic Surgery, Taegu Presbyterian Hospital during the period from 1962 to 1970 The most cases were treated conservatively and various method of treatment were adapted according to the condition of the fracture. All obtained satisfactory bone union but six cases of them resulted gun-stock deformity (reversed carrying angle) of the elbow, Two of these underwent supracondyIar wedge osteotomy and gained satisfactory corrections.

Purpose: This study aims to verify the preoperative factor that can affect the footprint coverage during arthroscopic rotator cuff repair in full-thickness medium-size cuff tear and the change of footprint coverage on magnetic resonance imaging (MRI) at postoperative 6 months. Methods: A total of 30 medium-size full-thickness rotator cuff tears were analyzed. They were classified into complete footprint coverage group (CC, n=19) and incomplete footprint coverage group (IC, n=11) by arthroscopic findings and immediate postoperative MRI findings. MRI was performed before the operation, 1 day after the operation, and 6 months after the operation. Preoperative MRI evaluated the size of the anteroposterior tear width (cm), length of retraction (cm), fatty infiltration, and muscle atrophy. Postoperatively, footprint coverage, fatty degeneration, and muscle atrophy were evaluated. We compared healing and change of fatty degeneration between two groups. Results: The healing rate was significantly increased in the CC group (complete/partial healing, 10/9) compared to the IC group (complete/partial healing, 6/5) (p＜ 0.001). Six of 11 partial coverages (54.5%) were even improved to complete coverage at postoperative 6-month follow-up. However, the difference in footprint coverage did not affect the change of fatty degeneration at postoperative 6 months. Any change of fatty degeneration (FD) and initial FD of rotator cuff tendons were not correlated with healing (p＜ 0.05). Conclusion The footprint coverage can be changed in postoperative 6 months in MRI and anteroposterior tear size, retraction, fat degeneration, and muscle atrophy do not affect footprint coverage in medium-sized full-thickness rotator cuff tears.
