Twenty-one patients with fractures of the distal tibial metaphysis, some with minimal displacement in the ankle, were treated by percutaneous plate osteosynthesis with a narrow limited contact-dynamic compression plate. Using the classification by the Arbeitsgemeinschaft für Osteosynthesefragen and Orthopaedic Trauma Association, 17 fractures had no(More)
OBJECTIVES Thoracic myelopathy secondary to OLF is a rare disease described almost exclusively in Japanese patients. Few series of OLF in South Korean subjects has previously been published. This study is to describe the clinical and radiologic aspects, as well as surgical outcomes in a group of South Korean patients. METHODS A retrospective study of 8(More)
BACKGROUND The time for femoral lengthening is shortened if external fixation is combined with intramedullary nailing. However, several complications have been reported with this procedure. PATIENTS AND METHODS We retrospectively reviewed the outcome of femoral lengthening performed over an intramedullary nail using external fixation in 22 patients. These(More)
PURPOSE To evaluate the position of the screws and find the difference of clinical and radiologic outcome between the volar approach and the dorsal approach groups in percutaneous screw fixation for acute scaphoid fractures. METHODS Forty-one consecutive patients with an acute scaphoid fracture, who had percutaneous fixation via either the volar approach(More)
This retrospective study was performed to understand the clinical results after closed reduction and open reduction in 35 children (mean age 6.4 years) with completely displaced supracondylar fractures of the distal humerus between 1996 and 2000. Closed reduction (21 cases) was attempted, with open reduction (14 cases) indicated in irreducible cases with or(More)
As there are few reports on the difficulties of removing the locking compression plate (LCP), we prospectively investigated the incidence and difficulties in 58 patients in whom various types of LCPs were taken. From January 2004 to December 2007, we have removed 159 5.0-self tapping locking screws and 279 3.5- self tapping locking screws. All of the(More)
Although ipsilateral femoral shaft and neck fractures are difficult to treat, there is still no consensus on the optimal treatment of this complex injury. We report the results of treating the 17 fractures with a standard protocol of retrograde nailing for diaphyseal fractures and subsequent screw fixation for the femoral neck fractures. Seventeen injuries(More)
UNLABELLED Total hip arthroplasties with hydroxyapatite coatings have shown encouraging results after early-term followup. We presumed hydroxyapatite-coating on a smooth hemispheric press-fit acetabular cup would enhance bone osseointegration and maintain stability of cup after midterm (minimum 5-year) followup. Sixty-three patients had 70 consecutive total(More)
STUDY DESIGN We performed a prospective study to evaluate the reliability of using triggered electromyography (EMG) for predicting pedicle wall breakthrough during the placement of pedicle screw in adolescent idiopathic scoliosis surgery. PURPOSE We wanted to correlate pedicle wall breakthrough with the triggered EMG threshold of stimulation and the(More)
BACKGROUND Iliosacral screw fixation is a popular technique for treatment of unstable pelvic injuries involving the posterior ring. However, screw malposition may result in dangerous complications involving injury to adjacent neurovascular structures. This study was conducted in order to evaluate the results and efficacy of using three-dimensional(More)
