Anterior papillary muscle rupture caused by occlusion of the first diagonal branch is reported to be very rare. A 66-year-old woman was transferred to our hospital for acute myocardial infarction and cardiogenic shock. Echocardiography and angiography revealed severe mitral regurgitation caused by rupture of the anterior papillary muscle and the complete occlusion of the first diagonal branch. In an emergent setting, she had been successfully treated by mitral valve replacement and coronary artery bypass grafting. She was discharged on postoperative twelfth day without any event.

Purpose: The purpose of this study was to evaluate the results of treatment for longitudinal meniscal tear in ACL rupture patients by clinical evaluation and $2^{nd}$ look arthroscopy. Materials and Methods: Among the patients who underwent surgery due to ACL rupture and longitudinal meniscal tear between 2002~2009, 32 patients were selected for the study. The patients were devided into three groups; group 1 had repair, group 2 had partial menisectomy due to impossible to repair, group 3 had conservative treatment due to stable meniscus. Comparative retrospective analysis was applied with KT 1000 arthrometer, Lysolm' score, Tegner activity score, IKDC subjective score, and $2^{nd}$ look arthroscopy. Results: Lysolm' score, Tegner activity score, IKDC subjective score showed no statistical difference in all three groups. KT-1000 side to side difference improved from 6.2, 6.15, 6.38 before surgery to 2.56, 2.49, 2.58 after surgery in group 1, 2, and 3, respectively. In group 1, second-look arthroscopy revealed complete healing in 12 patients, incomplete healing without any clinical symptoms in 2, and healing failure in 1. In group 2, second-look arthroscopy showed partial regeneration on margin of meniscectomy. In group 3, second-look arthroscopy revealed complete healing in 2 patients, while 4 showed incomplete healing so that have repaired. Conclusion: In the study, the outcome was better when the stable longitudinal meniscal tear on posterior horn with ACL rupture had active treatment.

Background and Objectives : Microsurgical resection of intracordal cysts is technically difficult and challenging because the wall of cysts may be tightly attached to underlying vocal ligament and/or overlying epithelium, and therefore their thin wall will easily rupture during surgical dissection. We aimed to evaluate the voice outcomes of standard microflap subepithelial resection and the recurrence rate depending on the intraoperative rupturing of the cyst. Materials and Methods : Medical records of Samsung Medical Center, Seoul, Korea, were reviewed for sixty-four consecutive patients who received surgical resection of vocal cyst using microflap subepithelial dissection technique between the year 2004 and 2013. Meticulous dissection was performed to completely remove the cyst wall while preserving the mucosa and the lamina propria as much as possible. Voice outcomes and recurrence rates were compared according to the type, size and the intraoperative rupture of cyst. Results : Presence or absence of cyst rupture was clearly described in the operation records of 41 patients. Intraoperative rupture of the cyst occurred in 32 of 41 (78%) patients. The recurrence was detected in 5 of 64 (7.8%) total cases and 4 of 32 (12.5%) cases of ruptured cyst, but not in 9 cases of intact extirpation. Rupture was more common in case of mucous retention cyst compared with epidermoid cyst (p=0.036). Subjective and objective voice parameters were measured at before and 3 months after surgery, which improved regardless of the cyst rupture. Conclusion : Although complete microsurgical extirpation of intracordal cyst while keeping the cyst wall intact is technically difficult, meticulous dissection with maximal preservation of surrounding tissue may warrant the improvement of voice outcomes.

Purpose: Anterior drawer and varus stress radiographs are commonly to diagnose chronic lateral ankle instability. We compared the preoperative stress radiographs with the intraoperative radiographs under anesthesia to determine the accuracy and efficacy of stress radiographs in an outpatient clinical environment. Materials and Methods: Data was collected from patients who underwent a modified $Brostr{\ddot{o}}m$ operation for painful chronic unilateral lateral ankle instability between January 2014 and June 2016. Subjects were divided into three groups-complete tear, partial tear, and instability without rupture-according to the status of preoperative MRI findings of the anterior talofibular ligament. The anterior drawer and varus stress radiographs were taken preoperatively and intraoperatively under anesthesia. Results: Ninety-six patients, with a mean age of 29.63 years, were enrolled. There were 39, 46, and 11 patients in the complete tear, partial tear, and instability without rupture groups, respectively. On the anterior drawer and varus stress radiographs of the affected limb, talar anterior translation and varus tilting were significantly increased by 2.56 mm and $2.0^{\circ}$. The gaps between the unaffected limbs were also increased by 2.47 mm and $1.32^{\circ}$ after anesthesia. Although the stress radiographs were taken under anesthesia, the results were often smaller than the diagnostic value. Conclusion: Stress radiographs for painful chronic lateral ankle instability taken at the outpatient clinic might be inaccurate for diagnosis.

Rupture of an innominate artery caused by blunt chest trauma is extremel rare because this artery is short and relatively well protected by the bony cage. This report describes a 37-year-old male who sustained a blunt chest injury that resulted in an innominate artery rupture, detected by chest CT and thoracic aortography. The patient underwent an urgent operation through median sternotomy. A 3 by 3 m sized pseudoaneurysm of proximal innominate artery was found with a complete intimal tear. After the origin of the innominate artery was closed, the injured segment of artery was excised and an aorto-innominate artery bypass with a 10 mm Gore-tex graft was performed without use of a shunt. The patient was discharged 20 days later without neurologic complications and had equal blood pressure in both arms.

In clinical practice, recurrent Achilles ruptures have been noted to occurr at the original ruptured site. However, reports of new developed fresh rupture of the Achilles tendon in other sites are is extremely rare. Our report is about one uncommon case of a traumatic calcaneal tuberosity avulsion fracture following augmented repair, which was performed using the Krackow locking loop technique. We performed open reduction and intra-osseous fixation using a suture anchor. This procedure was done through the primary longitudinal incision for the calcaneal avulsion fracture fragment. After 6 months of follow-up, our patient has achieved a complete functional recovery and he can normally perform daily and work-related tasks without pain.

The dehiscence of saphenous vein grafts (SVGs) is a rare, often fatal, complication of coronary artery bypass grafting (CABG). We present the case of a 57-year-old man who underwent hemiarch graft interposition and CABG for a Stanford type A aortic dissection. Five months after discharge, the patient developed streptococcal sepsis caused by a hemodialysis catheter. Complete rupture of the proximal anastomoses of the saphenous veins and containment by the obliterated pericardial cavity was observed 25 months after the initial operation. The patient was successfully treated surgically. This report describes a patient who developed potentially fatal dehiscence of SVGs secondary to infection and outlines preventive and management strategies for this complication.

Background: Complicated acute type B aortic dissection is a life-threatening condition with high morbidity and mortality. The aim of this study was to report a single-center experience with endovascular stent-graft repair of acute type B dissection of the thoracic aorta and to evaluate the mid-term outcomes. Methods: We reviewed 18 patients treated for complicated acute type B aortic dissection by thoracic endovascular aortic repair (TEVAR) from September 2011 to July 2017. The indications for surgery included rupture, impending rupture, limb ischemia, visceral malperfusion, and paraplegia. The median follow-up was 34.50 months (range, 12-80 months). Results: The median interval from aortic dissection to TEVAR was 5.50 days (range, 0-32 days). There was no in-hospital mortality. All cases of malperfusion improved except for 1 patient. The morbidities included endoleak in 2 patients (11.1%), stroke in 3 patients (16.7%), pneumonia in 2 patients (11.1%), transient ischemia of the left arm in 1 patient (5.6%), and temporary visceral ischemia in 1 patient (5.6%). Postoperative computed tomography angiography at 1 year showed complete thrombosis of the false lumen in 15 patients (83.3%). Conclusion: TEVAR of complicated type B aortic dissection with a stent-graft was effective, with a low morbidity and mortality rate.

Twelve dogs weighing less than 10 kg underwent unilateral TTO to stabilize the stifle joint with cranial cruciate ligament rupture. Surgical findings, intra-operative and post-operative complications were recorded. Radiographic examinations were performed for 8 weeks following surgery. Postoperative outcome was evaluated using a visual analogue lameness scoring system. Mean preoperative PTA (the angle created by the intersection of the tibial plateau extrapolation line and the patellar tendon) was 103.8 degrees. Mean tibial wedge angle was 16.6 degrees. Mean postoperative PTA was 92.1 degrees. Intraoperatively, fracture through the caudal tibial cortex occurred in all dogs, through the distal tibial crest cortex in 2 dogs, through the lateral tibial cortex in 2 dogs and through the fibula in 1 dog. Four-week postoperative radiographs demonstrated evidence of progressive bone union at osteotomy site and complete unions were identified at 8 week in 10 dogs. All dogs were healed in 11 weeks. Most of dogs revealed weak lameness in 4 weeks and normal ambulation in 8 weeks postoperatively except for only one dog returned in 11 weeks. Despite frequent minor complication, it appears that the TTO is an alternative procedure for management of cranial cruciate ligament rupture in small breed dogs.

Purpose: To report the clinical results of patients treated for a rupture of the distal tendon of biceps brachii Materials and Methods: Between February 1987 and March 2004, we treated 16 patients with a rupture of the distal tendon of biceps brachii. 9 of 16 patients underwent surgical treatment. All cases were male, median age was 26.3(range, 16-48) years. The mean interval between injury and surgery was 4.7 days (range, 1~36 days). Operative correction was performed anatomically, using the two-incision technique(3 cases) or one-incision technique(6 cases). Clinical outcomes were evaluated one year after operation by assessing the review about the physical examination finding and radiologic findings with surgical findings, range of motion, muscle strength, subjective satisfaction, activity and return to previous occupation. and via telephone interview in cases of conservative treatment. Results: In cases of surgical treatment, 85.8%, 86.3% of flexion-extension and supination-pronation motion than healthy side were measured respectively. 75% of flexion power than healthy side was measured. Eight of nine(89%) were very satisfied. Eightl of nine returned to original job. In cases of conservative treatment, 65% of flexion power than pre-injury state was reported. Four of seven were satisfied, two were dissatisfied, one was very dissatisfied. Three of seven returned to original job. Conclusion: Early anatomic reconstruction can restore more strength and endurance for supination and flexion range and power. Conservative management may be considered for partial injuries, but operative repair must be considered in complete rupture, athletes, patient with high activity.
