In unstable femoral trochanteric fracture, we usually used transversing K-wires through the lesser trochanter to achieve an anatomical reduction, and using sliding hip screws. However, in patients with comminuted lesser trochanter or osteoporosis, an intrusion of the wire into the lesser trochanter and/or iatrogenic intertrochanteric fractures were often resulted. Those who were not familiar with a technique of puncturing two holes through the lesser trochanter might have had to face some difficulties. In order to overcome aforementioned drawbacks, the authors had quite satisfactory results by employing the method of passing each of two wires above and below the iliopsoas muscle, and they were twisted posteriorly and then anteriorly; and finally they were pulled together posteriorly. Through this technique, both firm fixation of the lesser trochanter and more stable bony union were obtained.

Pseudoaneurysm is defined as the aneurysmal cyst resulted from partial or total rupture of vessel membrane, and it can be caused by fracture, operation, laceration, blunt trauma, osteochondroma and so on. When the displaced pelvic bone fracture is diagnosed, the traumatic pseudoaneurysm, which is frequently related by the direct injury of vessel, is one of the common complications, and it can result the massive hemorrhage even death. In case of the displaced pelvic bone fracture, surgeon should check the hemoglobin level and vital sign carefully for the possibility of vascular injury. Authors report the rare case of superior gluteal artery pseudoaneurysm without pelvic bone fractrure.

Fat embolism is a rare complication of multiple long bone fracture or extensive soft tissue injury. The pathogenesis of fat embolism has been poorly understood and definite pathogenesis and treatment were not fully established. Respiratory failure associated with fat embolism is a major cause of death, but is usually self-limited, and is responsive to intensive treatment. We have experienced fat embolism in cancellous bone fracture which occurred in spine, distal radius and talus. Patient's fractures were treated with conservative management. The patient was recovered from fat embolism with supportive treatment.

Acute osteomyelitis after the contusion is a rare clinical entity. The complications of contusion are large hematoma formation, compartment syndrome, myositis ossificans and acute osteomyelitis. Authors experienced an acute osteomyelitis in the shaft of the radius after contusion of the forearm and report this case with references.

PURPOSE: To develop a robot-arm type image-guided surgery system for percuatneous screw fixation of the sacro-iliac joint and to evaluate its accuracy. MATERIALS AND METHODS: We have developed an image-guided surgery system using a three-dimensional digitizer (Microscribe 3-D G2, Immersion, USA) and a personal computer. The registration error and target localization error at fiducial registration were measured 30 times for each using a phantom made with plastic pelvic bone model (Sawbones, USA). Sixteen 6.5 mm cannulated screws were inserted into four plastic bone models, and the accuracy was evaluated. RESULTS: The target localization error was 1.46+/-0.47 mm while the registration error was 0.73+/-0.23 mm. All of the 16 screws were inserted well across the sacro-iliac joint, and there was neither cortical breach nor collision between screws or washers. CONCLUSION: The accuracy of the developed system was similar to that of optical tracker-based navigation systems, and its helpfulness and usefulness was proven with simulation surgery using plastic bone models.

PURPOSE: To evaluate the outcomes of minimal anterior approach and thumb assisted technique, in children with Gartland type III supracondylar humerus fracture, who were operated by this technique. MATERIALS AND METHODS: Forty two children with Gartland type III supracondylar fractures of the humerus with severe swelling were taken up for minimal open reduction and K-wire fixation. The technique used was a minimal incision in the cubital fossa and thumb assisted reduction of the fracture. Stabilization of fractures was done with 1.6 mm Kirschner wires. RESULTS: The outcomes were excellent in 40 cases good in 2 cases. No complications including malunion or scar contracture were seen. CONCLUSION: This technique is safe, effective and can be used for irreducible, displaced supracondylar fractures of the humerus in children

Tibialis anterior muscle hernia is the most common hernia among lower extremity muscles. This condition can be diagnosed by physical examination and radiologic findings, especially by dynamic ultrasonography. There are surgical methods of treatment for muscle hernia, including direct repair, fasciotomy, fascial patch grafting using autologous fascia lata or synthetic mesh. We report a case of tibialis anterior muscle hernia treated with local periosteal rotational flap. Because there are several advantages to the local periosteal rotational flap, such as lack of donor site morbidity, lack of skin irritation, low cost, simplicity, and an easy approach, this technique could be an option for tibialis anterior muscle hernia.

A fracture of the humeral shaft can occur by direct or indirect injury. Most occur as a result of direct injury mechanisms such as falls from a height, direct blows, and traffic accidents. Recently, the population enjoying watersports for leisure is increasing and 'flyfish riding', in which passengers ride an inflatable raft drawn by a motorboat, may cause humeral shaft fracture as twisting and axial compression forces occur on the humeral shaft while boarding. Accordingly, the incidence of humeral shaft fracture is expected to increase as more people are expected to enjoy leisure sport activities such as 'flyfish riding'. We report 4 cases of humeral fracture that occurred during this activity in the year 2011.
