Cubitus varus, which includes deformities of varus, hyperextension and internal rotation, is the most common complication of supracondylar fracture of the humerus in children. For correction of cubitus varus deformity, many operative methods have been reported but postoperative results are not always satifactory. For the purpose of detection of the reason of postoperative residual deformity, we reviewed AP roentgenography of 22 patients of cubitus varus deformity in the view point that change of longitudinal axis of forearm contribute the residual deformity. The results are summerized as follows: 1. Degree of cubitus varus deformity was more severe in the patients whose interval between the injured time and visiting hospital for cubitus varus was longer. 2. Average proximal radial shaft angle was 10.99degrees +/-3.48degrees in normal limb and 15.72degrees+/-4.03degrees in affected limb and average ulnar shaft angle was 7.86degrees+/-3.60degrees, 10.54degrees +/-4.02degrees (P<0.05), respectively which were all significant value statistically (P<0.05). Average distal radial shaft angle was 10.21degrees 2.37 in normal limb and 11.21degrees +/-1.51degrees in affected limb and statistically insignificant (P>0.05). 3. More severe cubitus varus deformity revealed more change of proximal radial shaft angle of attected limb compare to normal limb. Based on these results, we concluded that correction of the cubitus varus deformity should not be delayed in order to minimize the secondary change of longitudinal axis of foream bones and to obtain satisfacotry cosmetic outcome.

Fractures of the capitellum humeri are rare and the recommendations for treatment vary. It can involve a significant portion of the articular surface, rendering the elbow joint unstable. In this situation, it is desirable to reduce and internally fix the capitellar fragment, because this restores the articular surface and augments joint stability. We experienced two cases of capitellar fractures which one case was spontaneously anatomical reduced and the other case was treated by open reduction. In one case the capitellar fragment was spontaneous reduced to a stable position although it was noticed radiographically as an unstable displaced fracture preoperatively. The other case was treated by open reduction and internal fixation with 3.5mm, small, AO, cannulated screw and K-wire. Both cases are reported here with references.

We evaluated an effect of the distance between the incision line and corneal limbus on surgically induced astigmatism in sutureless cataract surgery with scleral tunnel incision. We made a 6mm scleral tunnel incision 1.0mm from the limbus (Group 1, 24 eyes) and 2.5mm from the limbus (Group 2, 30 eyes) and implanted polymethylmethacrylate (PMMA) intraocular lenses with a round optic of 6mm following phacoemulsification. We employed the Jaffe method and Cravy method of vector analysis to evaluate the change of Surgically induced astigmatism. The mean surgically induced astigmatism using Jaffe method was 1.24 D and 0.98 D one day after surgery in Group 1 and 2, respectively. The difference between them was statistically significant(p<0.01) and became insignificant(p>0.05) after postoperative one week. In the superior incision cases, the difference using Cravy method was not statistically significant for whole followup period. In the temporal incision cases, the surgically induced astigmatism was 0.39 D and 0.02 D one day after surgery in Group 1 and 2, respectively. The difference was statistically significant(p<0.05) and became statistically insignificant(p>0.05) after postoperative one week. In this study it was found that a distance of incision line from corneal limbus longer than 1 mm was not an important factor in influencing the surgically induced astigmatism one week after sutureless cataract surgery using a watertight scleral tunnel incision.

We performed an analysis of corneal astigmatism of 123 eyes with suturing(sutured group) and 56 eyes without suturing(sutureless group) after phacoemulsification and PCL implantation through 7.0 mm straight incision wound 2.0-2.5 mm from superior limbus by use of algebraic and vector methods for two years following surgery. In both groups, the amount and axis of astigmatism were continued to change for 2years(p>0.05). The amount of astigmatisms in sutureless group was less than in sutured group until 2 months postoperatively(p<0.01), no significant difference from 3 months to 6 months postoperatively(p>0.05). Astigmatic changes in sutureless group were stable and had lower against-the-rule shift than the sutured group after 6 months postoperatively(p<0.01). Surgically induced astigmatism was stabilized after 1 month postoperatively in sutured group and after 2 weeks psotoperatively in suture less group(p<0.01), and it was lower in suture less group than sutured group during the two years postoperatively.(p<0.01).

The arthroscopic procedure has been one of the useful treatment modalitis in osteoarthritis of the knee, which does not respond to conservative treatment. Authors reviewed the resuJts of 61cases of 61 patients(18 males and 43 females) that had been treated with arthroscopic procedures including arthroscopic simple )avage, partial menisectomy, removal of the loose bodies, synovectomy and chondroplasty. The purpose of this study is to evaluate indication and effectiveness of arthroscopic surgery for osteoarthritic knee. 1. Seventy-one percent of sixty-one patients had relief of pain and other clinical symptoms after arthroscopic procedures. 2. Sixty-one pereent were still good at last follow-up more, than one year. 3. The favorable results were obtained after removal of loose bodies or partial menisectomy in association with osteoarthritic knee cornpared with the other procedures. And the poor results were obtained in patients with severe degenerative changes and severe cartilage defects of both femoral condyles. 4. The normal-alignment knees had much better results after arthroscopic surgery compared with valgus or varus knees. Our results suggest that arthroscopic surgery can be one of the good alternative treatment methods for osteoarthritic knee and a time-saving procedure before arthroplastic surgery.

Brachiocephalic venous aneurysm (BVA) development is an extremely rare, particularly as a primary vascular disorder. BVAs may be misinterpreted as lymphadenopathies owing to the variable degrees of enhancement seen in imaging studies, especially among patients with underlying malignancy. We report a BVA that mimicked lymph node metastasis on CT in a 60-year-old female who had undergone subtotal gastrectomy for stomach cancer. After followup chest CT with different bolus times and Doppler ultrasonography, a venous aneurysm originating from the brachiocephalic vein was diagnosed. We emphasize that, to make an accurate diagnosis, physicians should be aware of the potential diagnostic pitfalls and have a high index of suspicion for BVA when encountering certain lesions in the cervical area.

To investigate long term effects of CAPD on the left ventricular function in end-stage renal disease patients, M-mode echocardiographic studies and measurement o fsystolic time intervals were performed in 20 CAPD cases, 28 hemodialysis cases and 29 uremic controls. Compared to the uremic control grup, the patients on CAPD treatment revealed significant improvement of ventricular contractility and reduction of volume. On the other hand in hemodialysis group, even though there was improvement of ventricular contractility, volume control was not adequate. In the systolic time interval measurement, it is postulated that increase of PEP/LVET ratio in CAPD group probably results from reduction of volume(preload) rather than from deranged ventricular function.

Postoperative hyphema following cataract extraction surgery is not usually a serious complication and clears quickly in the most cases. Sutureless cataract surgery was reported to have less incidence of postoperative hyphema than conventional cataract surgery. We analyzed the incidence of postoperative hyphema in each group according to the depth and the length of scleral pocket incision in 500 eyes with the sutureless cataract surgery via superior incision during two years. One day after surgery, 90 cases(18.0%) had hyphema and most of them(74.4%) showed grade 1 severity. The incidence of hyphema was 23.0% in the deep incision group and only 11.9% in the superficial incision group(p<0.01). The percentage of grade 1 hyphema was 66.6% in the deep group and 92.6% in the superficial group, then severity was greatly reduced in the superficial incision group(p<0.01). The incidence of hyphema in the group of 7.0 mm in length was highest among the 6.0, 6.5, 7.0 mm groups(p<0.01), and the shorter the incision length, the milder the serverity of hyphema(p<0.01). The incidence of hyphuma was the lowest(6.2%) in the group of 6.0 mm in length and superficial incision, and it was the highest(28.5%) in the 7.0 mm in length and deep incisional group(p<0.01).

OBJECTIVE: The purpose of this study was to determine the effect of bone cement augmentation of pedicular screwing in severe osteoporotic spondylolisthetic patients. METHODS: Twenty patients with spondylolisthesis (8 : spondylolytic spondylolisthesis 12 : degenerative spondylolisthesis) who had undergone pedicular screwing and interbody fusion for osteoporotic lumbar spine (T-score on bone mineral density<-3.0) from 2002 to 2005 were reviewed. Mean age was 62.3 years with 3 male and 17 female patients. Average follow-up period was 14 months. Average T-score on bone mineral density (BMD) was -3.62. After decompression of neural elements, about 6cc of polymethylmethacrylate (PMMA) was injected into the each vertebral body through transpedicular route. All patients underwent one level interbody fusion and pedicular screw fixation. Clinical outcome was assessed using Oswestry Disability Index (ODI) on the last clinical follow-up. In addition, a modified MacNab's grading criteria was used to objectively assess patient's outcome postoperatively. Radiographic analysis of sagittal contour was assessed preoperatively, immediately postoperatively, and at final follow-up including fusion rate. RESULTS: Eighteen of 20 patients were graded as excellent or good according to the modified MacNab's criteria. An significant improvement of ODI was achieved in both groups. Mean sagittal angle at the preoperative state, postoperative state and at the last follow-up state was 11.0 degrees, 20.1 degrees and 18.3 degrees, respectively, with mean sagittal angle correction gain 7.3 degrees. Firm fusion was achieved in all patients. There were one compression fracture above the fused segment after 6 months follow-up and one case of seroma. But, there were no postoperative complications related to bone cement leakage and pedicular screwings such as screw pullout or screw cut-up. CONCLUSION: Bone cement augmentation of pedicular screwing can be an effective procedure for osteoporotic lumbar spine in spondylolisthetic patients.

This study was to observe the changes of blastogenic responses of splenic lymphocytes to T-cell mitogens, N. fowleri lysate and concanavalin A, and serum antibody titer during the course of experimental PAM in mice. Naegleria fowleri, strain 0359, was cultured in the CGVS medium axenically and inoculated intranasally with 7 x 10(4) trophozoites for the development of experimental PAM in mice. The amoebae were subjected to ultrasonication and centrifuged at 20,000 g for 60 minutes, and filtered through 0.2 micro-m filter membrane. The supernatant, N. fowleri lysate, was used as T-cell mitogen, and antigen for ELISA. The serum antibody was examined by ELISA using peroxidase conjugate. Two hundred micro-l of 10(6) splenocytes in RPMI 1640 containing 10% fetal calf serum were added to each well of a microtiter plate. To each well was added T-cell mitogens, 100 micro-g/ml of N. fowleri lysate or 4 micro-g/ml of con. A, and the plates were incubated for 42 hours at 37 C in 5% CO(2) incubator. Cultures were pulsed with 1 micro-Ci of methyl-(3H)-thymidine 6 hour before harvesting. The mean blastogenic response of the splenocytes to N. fowleri lysate was reduced, whereas that to con. A was also reduced up to on day 11 after infection. Both of these results were statistically significant compared with those of uninfected control group. The serum antibody titers were increased gradually up to day 15. The results indicated that there was an impairment of the blastogenic response of splenocytes to N. fowleri lysate during the acute course of experimental PAM in mice.
