The medial collateral ligament(MCL) of the knee is the well established secondary restraint to the anterior displacement of the knee joint. However, there has been no report about the estimation of the anterior displacement in combined ACL(anterior collateral ligament) and MCL injures according to period when they were treated with conservative measures. This prospective study evaluated the changes of anterior displacement over time in combined ACL/MCL injury as the MCL injury heals after initial conservative measures. 19 patients who had combined ACL/MCL injury were followed during twelve months after injury. All patient had a positive Lachman test and were evaluated the side to side differences on KT-2000 knee arthrometer(Medmetric, San Diego, California) testing under 20 Ibs anterior tibial loading at 30 degree knee flexion. The stability of the knee was assessed using KT-2000 knee arthrometer every 8 weeks with clinical examination prospectively. They were treated with CI (Combined instability) brace (Smith & Nephew, Carlsbad, California) as conservative measures. Overall, Initial side to side difference of the anterior displacement was averaged 5.21mm (range,4.0-7.0mm) and 3.30mm (range,2.0-5.5mm) finally. According to the classification of MCL injury, in Grade III groups, they had the greatest initial anterior displacement about 6.4mm, but tight- ened the most to 3.08mm finally. In Grade II and Grade I groups they showed 2.97mm and 2.13mm side to side difference (p>0.01). However in Grade I, the anterior displacement were decreased by 4 months after injury but, it were increased at 6 months after injury. In Grade II and III, the decrement of the anterior displacement were continued by 6 months after injury, but they were not changed after that. The data was analyzed by General Linear Model Procedure method. Conclusively, the anterior displacement of knee in patients with combined ACL/MCL injury was diminished with the time in the majority of patients as the MCL healed. It means that the MCL was the stabilizer to the anterior displacement of the knee under the anterior tibial loading.

The goal of fracture treatment is to restore the patient to pre-injury function level. But the outcome assessment after orthopedic interventions has usually focused on physician-defined parameters of technical success, such as fracture union, alignment and range of motion rather than patient function and quality of life. However, the correlation among improvements in these parameters and functional status, psychosocial well being is inconsistent and weak in the elderly. Therefore authors assessed the functional status after surgical intervention of hip fractures in the elderly with functional recovery score(FRS). Independence in basic activities of daily living, in instrumental activities of daily living, in mobility, freedom from pain and intact memory were assessed in 133 hip fractures in the elderly. The hip fractures in the elderly resulted in 24.8% loss of function after the first year. The older the age, the more the loss of function after surgery of hip fractures. The more functional loss was observed in female patients and in patients with poor postoperative radiological results, but statistically insignificant (P>0.05). The more functional loss was observed in patients with underlying medical disease preoperatively and it was statistically significant (P<0.05). We recommend the evaluation of functional status in the elderly after hip fractures.

The crossing laminar screw fixation might be the most recently developed approach among various fixation techniques for C2. The new construct has stability comparable to transarticular or transpedicular screw fixation without risk of vertebral artery injury. Quantitative anatomical studies about C2 vertebra suggest significant variation in the thickness of C2 lamina as well as cross sectional area of junction of lamina and spinous process. We present an elderly patient who underwent an occipito-cervical stabilization incorporating crossed C2 laminar screw fixation. We preoperatively recognized that she had low profiles of C2 lamina, and thus made a modification of trajectory for the inferiorly crossing screw. We introduce a simple modification of crossing C2 laminar screw technique to improve stability in patients with low laminar profiles.

OBJECTIVES: It is known that a great extent of radiation is emitted from the medical instruments used in hospitals and that radiation exposure can cause thyroid cancer. However, the correlation between occupational radiation exposure in hospitals and thyroid disease is not extensively recognized. METHODS: The subjects of the study were female nurses, who worked at a single hospital and female, who had undergone a health examination at the same hospital during the same period. The 1,024 nurses and 2,631 healthy women were enrolled for the present study. All the participants were screened using thyroid ultrasonography, and fine-needle aspiration & cytology was performed on potentially malignant nodules. RESULTS: Thyroid nodules were present in 315 nurses (30.8%) and 1,023 health check-up female (38.9%). Typically, 107 nurses (10.4%) and 201 health check-up female (7.6%) had suspicious nodule and were further tested with ultrasonography guided fine-needle aspiration & cytology. The 16 nurses (1.6%) and 38 health check-up female (1.4%) were diagnosed with thyroid cancer. The prevalence of thyroid nodules was enhanced in both the groups and a significant increase was noted in health check-up female group (P<0.05); however, no difference was seen in the incidence of thyroid cancer in both the groups (P>0.05). CONCLUSION: In our study, working in a hospital does not increase the prevalence of thyroid nodules or thyroid cancer.

Injection medialization laryngoplasty is a procedure that has many advantages in treating vocal fold paralysis; however, undesired complications can occur. We experienced a case of a pulmonary embolism, suspected in a patient who had undergone an injection laryngoplasty with calcium hydroxylapatite (CaHA). The patient suffered dyspnea after undergoing the injection laryngoplasty. Chest embolism computed tomography (CT) scan revealed a new lesion of enhancing materials at the pulmonary vasculature in the right upper lobe. The CaHA embolism was suspected, and the patient was treated with warfarin for 12 months. The patient's symptom of dyspnea nearly disappeared and a follow up chest embolism CT scan revealed no signs of the previous lesion. Thus, we would like to report this rare case along with a review of the literature.

Voice changes developing after endotracheal intubation during right hemicolectomy with endotracheal intubation have been found to be due to a right recurrent laryngeal nerve palsy in 43-years-old male patient. It was likely that the inflated cuffed tube rode up to the level of the cricoid cartilage during the course of surgery as traction was placed on the endotracheal tube because the condenser humidifier and breathing circuit weighed heavy. Cuff overexpansion, in addition to muscle relaxation and decreased tracheal elasticity were considered as contributing factors of vocal cord palsy. We believe that tube traction and cuff overexpansion were the mechanism of vocal cord palsy in our patient. So we recommend the routine use of tube stand so that weigh of the breathing circuit does not transmit traction to the endotracheal tube. Concurrently, filling the cuff with a sample of the inspired mixture of gases, saline and 4% lidocaine in special cases or regular deflation of the cuff must be considered.

A thyroglossal duct cyst (TGDC) is one of the most common causes of anterior midline neck mass. Successful management of a TGDC requires histopathology and an understanding of the embryogenesis of the thyroid. Traditional TGDC surgery uses a transcervical approach, which results in an external neck scar. In contrast to the surgical removal of a benign neck mass, TGDC surgery should include removal of the cyst, the hyoid bone, and the thyroid remnant track from the foramen cecum to the hyoid bone. Considering the embryological development of the TGDC, it was evident to us that an entirely transoral approach to the TGDC region was an option. Before its descent, the TGDC originates from the bottom of the tongue. The TGDC is located behind the strap muscles of the neck and the hyoid bone. Following this naturally predetermined access alongside the TGDC, we were able to develop a new surgical approach to the TGDC area and introduced the transoral TGDC excision.
