PURPOSE: The purpose of this study is to describe the anglographic findings of collateral vessels in cervicofacial vascular lesions with previously ligated carotid arteries and to evaluate the extent of anglographic assessmant needed before embolization. MATERIALS AND METHODS: We retrospectively reviewed 10 cervicofacial vascular lesions with previously ligated carotid artery, which were 6 cases of arteriovenous malformation, 2 cases of carotid cavernous fistula, 1 case of hemangioma and 1 case of arteriovenous realformation with carotid cavernous fistula. The previously ligated arteries are proximal external carotid artery (n=5), branches of external carotid artery (n=2) and common carotid artery (n=3). Common carotid artery or internal carotid artery (n=9), vertebral artery (n=5), ipsilateral external carotid artery (n=4), contralateral external carotid artery (n=5), costocervical trunk (n=2), thyrocervical trunk (n=2) were assessed by conventional angiography. Angiography of both carotid and vertebral arteries was performed in 5 cases. RESULTS: The collateral vascular channels were inferolateral trunk of internal carotid artery (n=8), vertebral artery (n=5), contralateral external carotid artery (n=5), ipsilateral external carotid artery (n=4), deep cervical artery (n=2) and ascending cervical artery (n=l). Embolizations were performed in 9 cases with operative cannulation(n=4), embolization via collateral branches of ipsilateral external carotid artery (n=l), embolization via collateral branches of contralateral external carotid artery (n=3) and balloon occulusion via direct puncture (n=l). CONCLUSION: The collateral channels in cervicofacial vascular lesions with previouly ligated carotid artery were inferolateral trunk of internal carotid artery, contralateral or ipsilateral external carotid artery, vertebral artery, deep cervical artery and ascending cervical artery on angiography. Complete anglographic assessment of possible collateral channels is mandatory for the effective and safe embolization.

Prediction of acetabular development after reduction in treatment of developmental dysplasia of thc hip (DDH) is earlier, the hetter results because it would help ensure optimal timing of additional procedure if necessary. In this respect, authors reviewed retrospectively the radiographs of the hips of 35 children with DDH who had unilateral involvement and treated hy senior author (S.H.Lee) from the heginning with single successful attempt of reduction. The radiographs which were made at the time of initial diagnosis, one, two year nfter reduction und final follow up were assessed of teardrop figures. The results of treatment were classified as satisfactory group(CE > 10degrees ) and unsatisfactory group(CE < 10degrees) judged hy center-edge angle(CE degrees) at final follow-ups. 1. The teardrop figures were classifiable into 4 distinct groups as i)absent. ii)V-shaped, iii)Ushaped, iv) inverted D-shaped. 2. The teardrop figures in normal sides of hip were all U-shaped. 3. In dislocated but with satisfactory result group(24 cases), absent at 2 cases(8%), U-shaped teardrop was seen at 13 cases(54%), V-shaped in 9 cases(38%), and inverted 2-shaped in 0 case at I year after reduction. 4. In dislocated but with unsatisfactory result group( 11 cases), they were mostly of V-shaped(7 cases, 64%). The rest were of ahsent in 4 cases(36%) . hut none of U-shaped and inverted 2-shaped. In conclusions, teardrop figures appeared as significant predictor of future development of hip joint. Teardrop figure which stay as V-shaped at one year after reduction seems suggestive of insufficient reduction of DDH, therehy calls for early additional procedure.

4.Radiologic and clinical outcomes of an arthroscopic bridging graft for irreparable rotator cuff tears with a modified MasonAllen stitch using a plantaris tendon autograft: a case series with minimum 2-year outcomes
Clinics in Shoulder and Elbow 2023;26(4):406-415
Background:
Surgical management of a massive rotator cuff tear (RCT) is always challenging. This study describes the clinical and radiological outcomes of patients who underwent bridging grafts using a plantaris tendon for an irreparable RCT.
Methods:
Thirteen patients with a massive RCT were treated with arthroscopic interposition of a folded plantaris tendon autograft between June 2017 and January 2020. For clinical evaluation, a visual analog scale (VAS), American Shoulder and Elbow Surgeons (ASES) score, Disabilities of the Arm, Shoulder, and Hand (DASH) score, Constant-Murley score, and range of motion values were collected. For radiographic evaluation, standardized magnetic resonance imaging and ultrasonography were performed to check the integrity of the interposed tendon.
Results:
A statistically significant improvement at the final follow-up was evident in scores for the VAS (−3.0, P=0.003), ASES (24.9, P=0.002), D ASH (−20.6, P=0.001), and Constant-Murley values (14.2, P=0.010). In addition, significant improvement was shown in postoperative flexion (17.3°, P=0.026) and external rotation (27.7°, P<0.001). In postoperative radiologic evaluations, the interposed tendons were intact at the last examination in 12 of the 13 patients. No complications related to donor sites were reported.
Conclusions
An arthroscopic bridging graft for irreparable RCTs using a modified Mason-Allen stitch and a plantaris autograft resulted in improved short-term radiological and clinical outcomes. Graft integrity was maintained for up to 2 years in most patients.Level of evidence: IV.

The physeal injuries in children occur result of trauma, infection, metabolic or ischemic disease, and these conditions cause significant problems, such as growth disturbance, deformity and premature closure of physis. The authors experienced 7 cases of children who had angular deformity of knee and limb shortenings, but no history of obvious causes of physeal injury. All of these cases had severe osteoporosis and underlying disease, which were osteogenesis imperfecta, fibrous dyplasia and long term steroid therapy. The purpose of this study are evaluation of pathomechanism of physeal injuries in severe osteoporotic children. Patients were range of age from 4 to 9 years and had common clinical features, which were angular deformities of knee, limb shortening. Also they had common radiographic findings, that were severe porosis, metaphyseal sclerosis and in some cases, pop corn like calcification around physis. At this, we supposed that chronic mechanical stress in osteoporotic bone make physis be damaged due to loss of capillary circulation and this event appear to result from collapse of bone plate, through which epiphyseal vessel penetrate. In conclusion, the children with severe osteoporosis should be observed carefully about physeal injuries, which pathomechanism are perhaps deprivation of capillary circulation through bone plate. Therefore, We should try to protect bone plate by being conscious of its existence.

Purpose:
This study sought to investigate the appropriate indications for intra-articular injection of hyaluronic acid in ankle osteoarthritis, its efficacy at each stage of osteoarthritis and to compare the efficacy related differences at each stage.
Materials and Methods:
A retrospective study was conducted from January 2016 to September 2019 on 43 patients (50 cases) diagnosed with ankle arthritis and given intra-articular injection of hyaluronic acid. Patients were classified according to the modified Takakura ankle osteoarthritis stages. Stage 2 comprised 24 cases; stage 3A, 15 cases; stage 3B, 8 cases; and stage 4, 3 cases. The clinical evaluation was carried out using the visual analogue scale (VAS), American Orthopaedic Foot and Ankle Society (AOFAS) score, and the Foot and Ankle Outcome Score (FAOS). The patients’ satisfaction with the injection was evaluated at 1 year after injection. A radiographic evaluation was performed to gauge the progression of osteoarthritis before and after the injection.
Results:
The VAS, AOFAS score, and FAOS at 3 months and 1 year after injection showed statistically significant improvements compared to those before the injection. There was a significant difference in the VAS for each stage over time; however, this was not the case with the AOFAS score and the FAOS. A significant improvement of the VAS after injection was seen only in stage 3A when compared with the other stages. The overall satisfaction rate with the injection was 90%. There were no ankle osteoarthritic stage changes in the serial follow-up radiograph.
Conclusion
Intra-articular injection of hyaluronic acid resulted in a significant clinical improvement up to 1 year after the injection.Therefore, the intra-articular injection of hyaluronic acid could be a treatment option for ankle osteoarthritis.

OBJECTIVE: To investigate the histologic features of the uterus and adnexae extirpated from gender identity disorder (GID) patients that received depot androgen injection. METHODS: We reviewed the histologic findings of the uterus and adnexae removed from sixteen GID patients, who had taken depot androgen injection for 5~168 months. RESULTS: Fourteen patients (87.5%) showed the atrophied epithelium of exocervix and all of 16 patients (100%) showed the atrophy of endometrium. Seven patients (43.7%) showed multiple cystic follicles in the ovarian cortex and 6 patients (37.5%), 3 patients (18.7%) showed corpus albicans and corpus luteum, respectively. CONCLUSIONS: Exogenous androgen induced atrophy of cervix and endometrium. This effect was more prominent in the endometrium. In addition, PCO-like histologic features were observed in the ovary.

Hypermobility of the bladder neck in response to increased intraabdominal pressure is the anatomical cause of female stress urinary incontinence ( SUI) and the degree of bladder neck movement has been used to classify SUI patients and to guide management decisions. We performed transvaginal ultrasonography in 14 SUI patients and 20 normal female as control to assess its role on the demonstration of the anatomical features associated with SUI. We adopted three anatomical factors in the sagittal plane which affect the bladder neck mobility , vertical (JY) and horizontal(JX) distance difference between pubic symphysis and bladder neck, and rotation angle difference(JZ) composed of by pubic symphysis and bladder neck during rest and stress states. There were significant differences in Y and Z between the two groups. Three months after corrective surgery for SUI these two factors showed significant improvement in all patients. It could be concluded that transvaginal ultrasonography is a safe and reliable method to diagnosis and evaluate the postoperative outcome for SUI.

STATEMENT OF PROBLEM: In spite of increasing dental treatment for the disabled, there was no collected data on prosthodontic treatment status and dentists' perceptions in Korea. PURPOSE: The purpose of this study was to research the dentists' perceptions about current prosthodontic treatment status for the disabled in Korea and to suggest public health policies for the disabled. MATERIAL AND METHODS: Total of 68 dentists who have regularly treated the disabled were asked to fill questionnaires regarding prosthodontic treatment for the disabled. RESULTS: 1. 45.6% of dentists felt the necessity of an esthetic prosthesis for the disabled. However, 54.3% of dentists reported the improvement of access to implant,orthodontic and esthetic treatment is needed. 2. Most (79.4%) of the dentists thought it is imperative for the government to support the disabled to maintain adequate oral health by providing at least 50% of charge in their prosthesis. CONCLUSION: Through this research, 97.1% of dentists answered that the current prosthodontic treatment status for the disabled in Korea is poor. This indicated the necessity of the financial support from the government for the disabled.
