Background: The purpose of this study is to evaluate the efficacy of computed tomography (CT) scans compared with plain radiographs on detecting the involvement of the sigmoid notch.

Methods: This study involved 121 cases diagnosed as the intra-articular distal radius fracture and performed post-reduction CT scans. We determined the presence of the sigmoid notch involvement with both plain radiographs and CT scans and compared findings of plain radiographs with CT scans about the incidence and the pattern of injuries.

Supraclavicular brachial plexus blocks are not common in pediatric patients due to the risk of pneumothorax. Ultrasonography is an important tool for identifying nerves during regional anesthesia. Directly visualizing the target nerves and monitoring the distribution of the local anesthetic are potentially significant.

Background: Ankle valgus deformity secondary to proximal migration of the fibula following an Ilizarov tibial lengthening has not been discussed in detail in the literature. The purposes of this study were to determine the underlying mechanism of and to identify factors associated with proximal migration of the fibula that caused ankle valgus deformity after an Ilizarov tibial lengthening.

Methods: We reviewed the outcome of seventy-four bilateral Ilizarov tibial lengthenings for short stature in thirty-seven patients.

Study Design: A retrospective study.

Purpose: To compare the level of restoration of the vertebral height, improvement in the wedge and kyphotic angles, and the incidence of complications in osteoporotic compression fracture in patients treated with either kyphoplasty or lordoplasty.

Overview Of Literature: Kyphoplasty involves recompression of the vertebral bodies.

Background: There are no reports of the pressure changes across the foot after extraarticular subtalar arthrodesis for a planovalgus foot deformity in cerebral palsy. This paper reviews our results of extraarticular subtalar arthrodesis using a cannulated screw and cancellous bone graft.

Methods: Fifty planovalgus feet in 30 patients with spastic diplegia were included.

Background: The mechanism by which mutant cartilage oligomeric matrix protein (COMP) induces a pseudoachondroplasia phenotype remains unknown, and the reason why a mutation of a minor protein of the growth plate cartilage causes total disruption of endochondral bone formation has not yet been determined. The current study was performed to investigate the effects of mutated COMP on the synthesis of the cartilage-specific major matrix proteins of Swarm rat chondrosarcoma chondrocytes.

Methods: The Swarm rat chondrosarcoma chondrocytes transfected with a chimeric construct, which consisted of a mutant gene of human COMP and an amino acid FLAG tag sequence, were cultured in agarose gel.

Background: Brace prescription for children with diplegic cerebral palsy challenges the clinician with a variety of options and little evidence for rational decisions. Previous studies have indicated that ankle-foot orthoses improve toe-walking, but it is unclear if any brace is better than another. The goal of the present study was to compare the effectiveness of hinged and dynamic ankle-foot orthoses in terms of improving gait and motor function in a homogeneous group of children with diplegic cerebral palsy exhibiting a jump gait pattern.

Background: Although long bone defects may be treated by callus distraction, frequent complications arise from the long duration of external fixation. To reduce such complications, bone transport over an intramedullary nail (BTON) has been done for tibial bone defect.

Methods: In 12 patients (mean age, 46.

Synopsis of recent research by authors named "Jae Young Roh"

  • - Jae Young Roh's research primarily focuses on orthopedic and anesthetic procedures, particularly in the context of pediatric patients and bone-related conditions, as evidenced by studies on various techniques including supraclavicular brachial plexus blocks and tibial lengthening with Ilizarov fixators.
  • - Key findings from his studies highlight the efficacy of advanced imaging techniques like computed tomography in diagnosing complex fractures, and the potential complications associated with common orthopedic procedures such as the migration of the fibula in tibial lengthening.
  • - Additionally, Roh explores the effectiveness of different orthopedic devices, such as comparing various ankle-foot orthoses and surgical methods for managing conditions like osteoporotic vertebral fractures and congenital foot deformities.
