Ultrasongraphy is a safe, noninvasive examination which should be the first procedure in the workup of apatient with a definite or suspected pelvic masses. The diagnostic schemes were derived from correlating the sonographic features with histomorphology in 230 surgically proven pelvic masses. Besides separating pelvic masses into the conventional categories of cystic, complex and solid, grayscale sonographic features of a pelvic mass canbe used to subcategorized these masses into a more useful differential diagnosis. The results are as follows; 1.The most characteristic finding of uterine myoma was midly to mederately echogenic uterine enlargement (90.7%)with a lobulated uterine margin (62.8%), and often less echogenic than the normal uterine echoes. 2. The typical ultrasonographic finding of H-mole was uterine enlargement with multiple small vesicular patterns of intrauterincontents(93%). 3. The most frequent finding of cystic teratoma was cystic mass with echogenic foci(48%), but the echogenic appearance of the lesions was extremely variable. 4. The ultrasonographic findings of ectopic pregnancywere adnexal mass(comlex or cystic), decidual proliferation of the uterus, enlargement of uterine size, fluid incul-de-sac, deveiation of uterus by adnexal mass, and psuedointrauterine appearance. 5. Ultrasound provided information leading to the correct diagnosis in 57% of cases, contributory data in 21.3%, and non-specific information in 10.4%. Errors occured in 3.9% and false-negative in 7.4%.

PURPOSE: To evaluate the risk factors related to the development of new fractures in adjacent vertebrae after vertebroplasty. MATERIALS AND METHODS: The study was conducted on 46 patients in whom 296 patients were performed during last 9 years. We were especially concerned with the restoration rate of vertebral height and kyphotic angle and estimated them on simple X-ray films. RESULTS: In patients experienced subsequent vertebral fractures and no subsequent vertebral fractures after vertebroplasty, the mean height restoration rate of treated vertebra were 16.7% and 7.07%, and the kyphotic angle difference were 2.53 degree and 4.2 degree. The greater degree of height restoration of the vertebral body, especially in middle vertebral height and the lesser degree of kyphotic angle difference increased the risk of adjacent vertebral fracture risk. This results were available statistically (all p<0.05, Logistic regression test, SPSS 13.0). CONCLUSION: It may be thought that the vertebral body height restoration rate will become risk factor of adjacent vertebral fractures.

PURPOSE: To evaluate several risk factors related to re-ulceration of diabetic foot including psychosocial aspects such as familial support and degree of independence of patients' activity. MATERIALS AND METHODS: We reviewed medical records and performed telephone interview with eighty-five patients who had a history of hospitalization in our hospital due to diabetic foot ulceration from year 2002 to 2010. Based on the collected data, we analyzed several factors such as age, gender, prevalence duration, accompanying diseases, HbA1c level, degree of independence and familial support. RESULTS: The mean age was 61.4 years and most common in the 4th decade. There were 57 cases (67%) of recurrence, predominance of male. Eleven patients with recurrent diabetic foot ulceration had undergone major amputations. Psychosocial problems such as depression, insufficient familial support and mortality were more frequently observed in recurrent group. CONCLUSION: This study shows that psychosocial factor such as familial support for patient with diabetic foot could be important to reduce the recurrence rate of diabetic foot ulceration. Therefore, we should pay attention to strategic plans for prevention, screening, treatment, and aftercare through the prospective studies including psychosocial risk factor in diabetic foot ulceration.

PURPOSE: To present clinical results of proximal first metatarsal opening wedge osteotomy and low profile plate fixation in hallux valgus deformity. MATERIALS AND METHODS: Thirty-two patients (39 feet) underwent surgery for hallux valgus deformity. Fourteen patients (18 feet; Group A) underwent proximal first metatarsal opening wedge osteotomy fixed with low profile titanium plate (Arthrex(R)), and 18 patients (21 feet; Group B) underwent proximal chevron osteotomy with two K-wires. Improvement in hallux valgus angle (HVA), 1, 2 intermetatarsal angle (IMA), range of motion of 1st metatarsophalangeal joint, VAS score, and the length of first metatarsal on weight-bearing radiograph were evaluated preoperatively and at final follow-up. RESULTS: HVA improved from 36.2+/-6.6 degrees to 11.7+/-5.1 degrees, and 1, 2 IMA improved from 15.7+/-2.6 degrees to 7.2+/-1.9 degrees. VAS score improved from 7.2+/-1.2 to 1.4+/-0.9. There were no significant differences clinically and radiologically. CONCLUSION: Proximal first metatarsal opening wedge osteotomy with stable fixation using low profile plate may be an effective surgical option for correction of hallux valgus deformity.

PURPOSE: To evaluate the functional outcomes of the severely comminuted intra-articular calcaneal fractures that were selectively treated with primary subtalar arthrodesis. MATERIALS AND METHODS: This study is based on the 9 patients, 10 feet of intra-articular severely comminuted calcaneal fractures that were treated with open reduction and internal fixation with primary subtalar arthrodesis due to inability to reconstruct the subtalar articular surface with follow-up of more than 1 year. Postoperative clinical evaluation was performed with AOFAS Hindfoot functional scores. The patient satisfaction, returning to previous occupation and complications were also investigated. RESULTS: Follow-up period was average 20.3 months. Overall AOFAS functional score at final follow-up was average 71.8 points and VAS pain score was 3.9. Fifty percent of the patients were satisfied with the surgery and 80% of the patients were able to return to their previous occupations at average 8.4 months after trauma. Post-operative complications were 2 cases of sural nerve injuries and 1 hindfoot valgus malunion. CONCLUSION: We concluded that the primary subtalar arthrodesis is a viable surgical option for severely comminuted calcaneal fractures with favorable functional result and early returning of most patients to their previous occupations.

Three Stener-like lesions of the metacarpophalangeal joint of the fingers and a rupture of the first dorsal interosseous muscle mimicking the lesion in the index finger were observed. Two cases in the little fingers had a true Stener's lesion. In one case in the index finger, the ruptured ligament was retracted and located under the intact sagittal band, which was also observed by preoperative magnetic resonance imaging (MRI). Rupture of the first dorsal interosseous muscle was misdiagnosed preoperatively as a Stener's lesion in the index finger by ultrasonography. MRI should be an essential differential diagnostic exam for collateral ligament ruptures of the metacarpophalangeal joint of the fingers.

Purpose:
To identify the indication for recommending prebiopsy magnetic resonance imaging (MRI) to prevent prostate cancer missed diagnoses in cases without prebiopsy MRI.
Materials and Methods:
Between January 2017 and September 2020, 585 patients suspected with prostate cancer underwent prostate biopsy after MRI. For patients with visible lesions, MRI-targeted biopsy using an image-based fusion program was performed in addition to the 12- core systematic biopsy. Patients for whom MRI was performed in other institutions (n=4) and patients who underwent target biopsy alone (n=7) were excluded.
Results:
Of 574 patients (median prostate-specific antigen [PSA] level, 6.88 ng/mL; mean age, 68.2 years), 342 (59.6%) were diagnosed with prostate cancer (visible lesions=312/449 [69.5%]; nonvisible lesions=30/123 [24.0%]). The detection rates of visible lesions stratified using the Prostate Imaging Reporting and Data System score (3 vs. 4 vs. 5) were 30.9% (54 of 175), 61.2% (150 of 245), and 90.1% (127 of 141), respectively. Multivariate analysis showed that PSA density was a significant factor for presence of visible lesions, prostate cancer, and significant prostate cancer diagnosis. Among patients with positive lesions, 27 (8.2%) were diagnosed with prostate cancer concomitant with negative systematic biopsy results. A PSA density of 0.15 ng/mL/cm3 was identified as the significant cutoff value for predicting positive target biopsy in groups with negative systematic biopsy. Sixty of the negative target lesions (26.1%) were diagnosed using systematic biopsy.
Conclusions
To maximize cancer detection rates, both targeted and systematic biopsies should be implemented. PSA density was identified as a useful factor for recommending prebiopsy MRI to patients suspected with prostate cancer.
