There are few reports in the literature on how to care and manage bi!ateral congenital dislocation of the hip. Six patients have been encountered at this hospital from June 1979, of them four children had operative treat ment and the other two conservative. As a result of our experience about the management of bilateral congenital dislocation of the hip. The authors obtained the following conceptions; 1. The patient with bilateral dislocation was rather delayed in diagnosis. Therefore, in comp the treatment of bilateral cases was poorer than that of unilateral case. 2. In the case of the dislocated hip that might be easily reduced and maintained in the stab servative care was usually recommeded even in the older child. Unstable, unreduced hip,; hip in old children, the more definitive operation and internal & external rigid immobilization mandatory to get good result. 3. It might be beneficial to operate the more deformed and resistive hip first, and then to p with the same procedure 2 weeks after the first operation.

The purpose of this study is to make an emphasis the necessity of the dynamization after interlocking intramedullary nailing. We reviewed 75 cases of the fractures of the shaft of femur or tibia fixed with static interlocking intramedullary nailing. We excluded the cases in whom the locking screws were removed for the purpose of the relief of pain from the irriataion by those screws. The parameter we reviewed were the type of fracture, postoperative gap between the major fragments. Early callus formation, the union time, postoperative dynamization and controlled weight bearing. In those cases in which the contact surface between the major fragments was more than 50% and there noticed no early callus within 6 weeks after operation, the union time was shortened after dynamization, when the contact surface was less than 50% and there noticed no early callus, the union time was shortened after bone graft and dynamization which resulted in some shortening in the length in acceptable ranges. In cases with a major gap of more than 2mm, the union time was shortened after dynamization. The rate of early callus formation was a little higher in cases with postoperative controlled weight bearing than those to whom we did not permit a controlled weight bearing.

The “delta phalanx”, first named by BlundeII Jones in 1964, is a triangular(“delta-shaped”) or trapezoidal phalanx with C-shaped epiphyseal plate causing progressive angular deformity of the digit with growth. Neither splinting nor physical therapy is effective in improving the condition. Surgical correction is indicated and several methods of correction have been reported. Authors have experienced a rare case of “delta phalanx” occuring in the proximal phalanx of the syndactylous digit.

Fourty one cases of open fractures of tibial shaft complicated with varying degrees of soft tissue injuries were trested by one-plane unilateral external fixation with AO fixator. In seventeen csses among them, interfragmental lag screw fixation was applied in addition, for more rigidity and stability of the fixation. All of thern were followed up at least for one year and we obtained the following results. 1. Rigid stable external fixation provided by additional minimum internal fixation may not increase the rate of infection but rather enhance prompt primary bone healing. 2. One-plane unilatersl external fixation may facilitate good access to the wound for subsepuent reconstructive procedures, and enhance pain-free early full range of joint motion, thus promote early bone union. 3. Comparing with bilsteral fixation, there wss almost no difference in the union time of the fracture even with one-plsne unilatersl fixation.

Alveolar soft-part sarcoma is a rare malignant neoplasm. It occurs most commonly in the deep tissue of the extremity, particularly in the anterior aspect of the thigh. It usually presents as a slow-growing, painless mass with little functional impairment. Because of the relative lack of symptoms, it may be easily overlooked. The course of the disease tends to be long but unrelenting, and local recurrences are frequent. There were no lifetime cures in the reported cases. This tumor is relatively unknown to orthopaedic surgeons, and a wider knowledge of its characteristics may lead to its more frequent recognization, Recently, two cases of alveolar soft-part sarcoma were encountered on the orthopaedic department of Dong-kang Hospital, Ulsan. In case 1, the tumor was found in the vastus lateralis muscle; and in case 2, vastus intermedius muscle. The authors will present these cases in detail to provide a glance at this very rare but more frequently recognizable tumor, the alveolar soft-part sarcorna.

The purpose of this study is to validate the potential etiologic factors for temporomandibular disorder(TMD). TMJ arthroscopic examination was performed in upper joint compartment of 32 joints from 20 patients with mandibular fractures. Synovial fluid was collected from the upper joint space during pumping manipulation with normal saline. Cytologic smearing and histomorphologic exam of synovial fluid were performed in 15 joints. Prostaglandin E2(PGE2) concentration was measured in 11 joints. Leukotriene B4(LTB4) concentration was measured in 8 joints. There were several arthroscopic variables such as ecchymosis, fibrillation, and adhesion. Histomorphologic exam showed a variety of findings such as bloody smears, cellular cluster, degenerated cells and cartilage, undifferentiated crystal. Mean PGE2 concentrations were 316.5 pg/ml. Mean LTB4 concentrations were 45.9pg/ml. This study demonstrated a variety of findings on inflammatory and degenerative changes of TMJ. Because acute trauma such as mandibular fracture is a major etiologic factor in cartilage degradation and biochemical and intraarticular pathology, clinicians must identify and address TMJ signs and symptoms during follow-up periods in the long term.

PURPOSE: To measure the enophthalmos corrective effect after inferior orbital wall reconstruction, we compared preoperative and intraoperative exophthalmometric values with postoperative exophthalmometric values. METHODS: From January 2014 to April 2016, 60 eyes of 60 patients who underwent surgery for inferior orbital wall fracture were included. In Group 1, the exophthalmometric value was measured before surgery, during the operation, and 6 months after surgery using the Naugle exophthalmometer. In Group 2, the value was measured before surgery and 6 months after surgery using the Hertel exophthalmometer. The thickness of implants was determined by preoperative exophthalmometric values and overcorrection of 0.5 mm was performed in Group 1 patients with relatively large fractures. RESULTS: The mean age of the patients was 32.4 years in Group 1 and 34.3 years in Group 2. The mean duration between injury and surgery was 4.2 weeks in Group 1 and 2.3 weeks in Group 2. There was no statistically significant difference between preoperative exophthalmometric values in Group 1 (−1.78 ± 0.31 mm) and Group 2 (−1.81 ± 0.26 mm), but postoperative exophthalmometric values between Group 1 (−0.25 ± 0.78 mm) and Group 2 (−0.53 ± 0.46 mm) were statistically different (p = 0.034). CONCLUSIONS: The exophthalmometric values and wall fracture size are important factors for determining implant thickness of inferior orbital wall reconstruction. Intraoperative measurement of exophthalmometric values should be considered in inferior orbital wall reconstruction for enophthalmos correction.

PURPOSE: To describe the change of lacrimal gland volumes in Korean patients with thyroid-associated ophthalmopathy (TAO) via computed tomography (CT). METHODS: A retrospective review of CT images from 217 TAO patients and 135 control subjects was performed. The TAO patients were diagnosed between May 2005 and May 2014 and had a CT performed on initial presentation (330 orbital CT scans). These images were compared with 270 orbital CT scans from the control group, obtained between May 2013 and May 2014. An open source DICOM viewer was used to calculate the volume of the lacrimal gland. RESULTS: The mean volume of the lacrimal gland in TAO patients was 0.816 cm³ in the right orbit (standard deviation [SD], 0.048) and 0.811 cm3 in the left orbit (SD, 0.051), with no significant difference between right and left (p = 0.192). However, significant differences were observed between TAO patients and healthy individuals (p < 0.001). There was no significant difference between mean lacrimal gland volumes of males (0.812 cm³; SD, 0.037) and females (0.816 cm³; SD, 0.029) (p = 0.513). There was a negative correlation between gland volume and age in TAO patients (Pearson r = -0.479, p = 0.00). The subjective tearing (right: r = 0.244, p = 0.018; left: r = 0.226, p = 0.024), corneal superficial punctate keratopathy (right: r = 0.192, p = 0.040; left: r = 0.206, p = 0.036), and exophthalmometry (right: r = 0.182, p = 0.032; left: r = 0.180, p = 0.046) correlated with lacrimal gland volume. CONCLUSIONS: This study is the first to use CT images to calculate the lacrimal gland volume of Korean TAO patients. In TAO patients, the lacrimal gland volume was notably increased compared to control subjects. The lacrimal gland volume decreased with age, but there was no difference between gender and no difference between left and right. The lacrimal gland volume correlated with subjective tearing, corneal superficial punctate keratopathy and exophthalmometry.

Vinegar is a very popular ingredient used in many cuisines. It is also known for its beneficial health, beauty and possible weight-loss properties. The authors report on a patient who presented to the emergency department with unstable vital signs complaining of generalized abdominal pain after ingestion of 450 ml of apple cider vinegar. We documented a case of corrosive gastrointestinal injury with persistent metabolic acidosis occurring after ingesting apple cider vinegar with an acetic acid concentration of 12~14%. Toxic damage to the liver and kidney were also observed, peaking on post-ingestion day 3. The patient received supportive care and hemoperfusion for three days without much clinical improvement and died in the seventh day of intensive care due to disseminated intravascular coagulation and multi organ failure. Edible vinegar, when taken in large amounts, is capable of inducing corrosive injuries of the GI tract as well as severe systemic toxicities, such as metabolic acidosis. Safety precautions regarding vinegar deserve more public attention and clinicians also should be astute enough to recognize the potential damage accompanying vinegar ingestion.

Journal of the Korean Ophthalmological Society 2012;53(6):895-900
PURPOSE: The authors of the present study report treatment experience of acute myopia and branch retinal vein occlusion associated with phendimetrazine, a drug used for weight reduction. CASE SUMMARY: Case 1: A 32-year-old woman, previously devoid of ocular problems, visited our hospital with bilateral visual disturbance after taking phendimetrazine for weight reduction. Ciliochoroidal effusion and anterior shifting of the lens-iris diaphragm were observed, which resulted in a shallow anterior chamber, myopic shifting and an increase in intraocular pressure due to angle closure. The symptoms were relieved by discontinuing the use of phendimetrazine and administration of intraocular pressure-lowering agents. Case 2: A 26-year-old woman, previously devoid of ocular problems, visited our hospital with left superior visual field disturbance after taking phendimetrazine for weight reduction. The examinations revealed papilledema, disc hemorrhage and tortuous vascular changes in her left eye. Fluorescein angiography was performed, and retinal vein occlusion was diagnosed. The patient discontinued weight reduction agents and recovered while under observation. CONCLUSIONS: Phendimetrazine, used for weight reduction, can cause acute myopia via prostaglandin synthesis and retinal venous occlusion due to vascular constriction.
