The aim of this study was to compare the mechanical properties of 0.6 and 0.8 mm cerclage wires with the 1.0 mm cerclage wire in the twist, single-loop, double-loop, double-wrap, and loop/twist knot methods. Six stainless steel cerclage wires of various diameters in different knot methods were tied round a customized jig mounted on a load testing machine. The initial tension, initial stiffness, and yield load were evaluated. The failure mode of each cerclage was observed. For each wire size, the double-loop, double-wrap, and loop/twist knots showed significantly greater initial stiffness, and yield load than those seen with twist and single-loop knots. The single-loop knot showed the least initial stiffness regardless of the diameter. As the cerclage wire diameter increased, the cerclage tended to show significantly greater initial stiffness, and yield load. Failure modes varied depending on the knot configurations. Single-loop knots of smaller-diameter wires less than 1 mm had similar or lower initial tension, initial stiffness, and yield load than a twist knot. Owing to the variance in mechanical properties, the clinical application of the knot type should depend on the diameter of the cerclage wire.

Distal clavicular fracture frequently requires operative treatment due to high rate of non-union. The operative technique includes the tension band wiring, K- wire fixation, and cerclage wiring etc. Each method has disadvantages somewhat like pin migration or acromioclavicular joint injury and so on. For the distal clavicular fracture type 2a, because of its oblique fracture line, the cerclage wiring is suitable. We performed the cerclage wiring percutaneously under minimal incision without injury to periosteum for the patient who had the distal clavicular fracture type 2a, and the result was favorable.

Purpose: The purpose of this study is to report the effect of oriental treatments on the cervical incompetence. Methods: Treatment of incompetent cervix has traditionally been surgical correction of presumed physical deficit in tissue strength with an encircling or cerclage suture, placed electively between 12 and 15 weeks. Despite the prolonged controversy about the role of cerclage, a randomized trial of cerclage versus bed rest or no therapy in women with atypical history of incompetent cervix has not been concluded. We treated a 32-year-old female who had been suffering from cervical incompetence with Herbal medicine(Gamidangkwisan). Results: After oriental medical treatment, the clinical symptom of Cervical incompetence was improved and she was delivered in 42 weeks. Conclusion: This case study shows that the oriental medical therapy is effective in treating cervical incompetence. If we make more studies about this disease, it will bring the high satisfaction of patient and the improvement of treatment rate.

A 1.6-year-old, intact male beagle dog was presented with three day history of odynophagia and anorexia. According to the history and radiographic findings, the patient was diagnosed with esophageal and gastric foreign body due to ingesting fishhooks. Gastroesophagoscopy revealed that one fishhook located in the thoracic esophagus cranial to the heart base and the other located in the cardia region were connected with a single fishing line. Gastrotomy was performed to remove the fishhook in the cardia region and to sever the connecting fishing line. After gastrotomy, endoscopic attempts to remove the esophageal fishhook with a three, five pronged endoscopic grasping forceps, and a biopsy were unsuccessful because the fishhook was embedded deeply in the mucosa membrane. A handmade cerclage wire(16G) shaped like a snare forceps was advanced into the esophagus while visualizing the fishhook endoscopically. The cerclage wire was used to hang and retract the foreign body. The fishhook was retracted orally, resulting in successful removal. Ten days after the operation, the patient fully recovered and was discharged.

There has been considerable controversy concerning the methods for treatment of dislocation of the acromioclavicular joint, especially in grade III injury. The authors have treated 24 cases of the complete dislocation of the acromioclavicular joint from January 1990 to July 2000. We performed 14 cases of coracoclavicular wiring operation, 10 cases of modified Phemister operation and compared the results and complication of wiring operation with modified Phemister. The clinical results in modified phemister operation were excellent in 8 cases(80%), good in 1 case(l0%), fair 1 case(10%). In wiring operation, excellent is 11 case(78%), good is 2 case(14%), fair is 1 case(14%). The complications of modified Phemister operation were breakage and migration of K-wire in 2 cases. In wiring operation, breakage of wire was in 2 cases but migration was not showed. We prefered coracoclavicular wiring operation for dislocation of acromioclavicular joint of active young adults because of the following advantages: 1) violation of acromioclavicular joint can be avoided but rotation of the clavicle was not restricted. 2) The operation is simple to perform. 3) Postoperative immobilization is minimal. 4) Removal of the wire is easy because wire was not migrated when breakage of wire was occured.

Secondary soft tissue injuries can occur from the pressure of the displaced fragment of posterior calcaneal tuberosity in calcaneal tongue-type fractures and calcaneal tuberosity avulsion fractures. The soft tissue injury can be prevented by immediate reduction of the displaced fragments. Various techniques can be used to fix the fracture fragments, but the stability of fixation and minimal invasiveness to soft tissue should be considered. This paper reports the successful outcomes of patients with soft tissue compromises in calcaneal tongue-type fractures and calcaneal tuberosity avulsion fractures. The fixation technique of a large cannulated screw and simple cerclage wiring is believed to be a useful surgical option for the treatment of secondary soft tissue compromised calcaneal fractures.

A four months old, 3.6 kg intact female Miniature Dachshund dog was referred for non-weight bearing lameness at right hind limb due to car accident. On physical examination, the patient was non-weight bearing on the right hind leg and had moderate swelling in the proximal to middle tibia region. There was palpable crepitus. Radiographs revealed a slightly displaced, spiral, oblique fracture involving the proximal diaphyseal region of the right tibia. Fibular fracture was also noted. Internal fixation was performed to repair the fracture. Due to bowed shape of fractured tibia, it was not possible to apply K-wire, containing appropriate diameter ($60{\sim}80%$ of bone marrow diameter) for intramedullary fixation. We fixed the bowed tibia fracture using a smaller diameter (30% of bone marrow diameter) K-wire with cross pins and cerclage wires. Four weeks after the operation, radiographs demonstrated healing of the tibia fracture as well as the fibular fracture.

We aimed to propose a novel computational approach to predict the electromechanical performance of pre- and post-mitral valve cerclage annuloplasty (MVCA). Furthermore, we tested a virtual estimation method to optimize the left ventricular basement tightening scheme using a pre-MVCA computer model. The present model combines the three-dimensional (3D) electromechanics of the ventricles with the vascular hemodynamics implemented in a lumped parameter model. 3D models of pre- and post-MVCA were reconstructed from the computed tomography (CT) images of two patients and simulated by solving the electromechanical-governing equations with the finite element method. Computed results indicate that reduction of the dilated heart chambers volume (reverse remodeling) appears to be dependent on ventricular stress distribution. Reduced ventricular stresses in the basement after MVCA treatment were observed in the patients who showed reverse remodeling of heart during follow up over 6 months. In the case who failed to show reverse remodeling after MVCA, more virtual tightening of the ventricular basement diameter than the actual model can induce stress unloading, aiding in heart recovery. The simulation result that virtual tightening of the ventricular basement resulted in a marked increase of myocardial stress unloading provides in silico evidence for a functional impact of MVCA treatment on cardiac mechanics and post-operative heart recovery. This technique contributes to establishing a pre-operative virtual rehearsal procedure before MVCA treatment by using patient-specific cardiac electromechanical modeling of pre-MVCA.

A 22-month-old female mongrel dog weighing 4.8 kg was referred with chief complaint of bite wounds and lameness. The patient showed non-weight bearing lameness on left hindlimb and lateral instability of intertarsal joint. On radiograph, proximal intertarsal luxation between calcaneus and fourth tarsal bone was diagnosed. To imitate the long collateral and calcaneoquartal ligament, bone tunnels were drilled in the distal calcaneus and proximal fifth metatarsal bone. The figure-eight suture was placed with 0.5 mm cerclage wire through the predrilled holes. At 2 weeks after surgery, the lameness of hindlimb was still present. However, the patient had weight bearing lameness for 4 weeks after operation and was able to walk and run without lameness at 5 weeks after surgery. This case report explains the successful correction of intertarsal luxation with a single figure of eight wire suture in case of luxation to the intertarsal joint.
