Following a Lisfranc joint injury, stable fixation of the tarsometatarsal joints is crucial to avoid deformity and posttraumatic osteoarthritis, but the ideal method of fixation remains controversial. Kirschner wire (K-wire) fixation of all involved joints with cast immobilization resulted in loss of position, and was replaced by open reduction with improved fixation using transarticular screws...

Objective: The superiority of volar locking plate fixation and K-wire fixation on treatment of distal radius fractures was controversial. Thus, we performed a meta-analysis to compare the efficacy of volar locking plate and K-wires for distal radius fracture. Methods: We searched Embase, Medline and PubMed for randomized controlled trials which compare the effects of volar locking plate and K-w...

The goal of this research was to find the implant which would provide a better possibility of the fractured osteoporotic bone weight bearing after trochanteric fracture fixation. The authors constructed a new implant based on the conventional condylar plate, as part of a stabile triangular system. Because of the special oblique form of the screw which absolutely stabilizes vertical and horizont...

We describe the case of a patient with distal radius fracture who became unable to flex the distal interphalangeal joint of the index finger after internal fixation using a volar locking plate. There was palpable crepitus with active thumb motion, and wrist radiographs showed prominence of the volar plate at the watershed line. Therefore, our initial diagnosis was plate-induced closed rupture o...

OBJECTIVE The purpose of this study was to compare the stability and feasibility of four fixation constructs in a posterior column acetabular fracture: one reconstruction plate, one reconstruction plate and lag screw, two reconstruction plates, and a W-shaped acetabular angular plate. METHODS Twenty embalmed cadaveric pelvises with a posterior column acetabular fractures were allocated to one...

The aim of the present study was to investigate the clinical effects of lamina replantation with ARCH plate fixation on patients with thoracic and lumbar intraspinal tumors, following laminectomy. Thirteen patients with thoracic and lumbar intraspinal tumors underwent total lamina replantation with ARCH plate fixation and repair of the supraspinous ligaments, following laminectomy and tumor enu...

The intention of this study was to compare the biomechanical characteristics using 5 internal fixation methods used clinically to stabilize a pubic symphysis diastasis (PSD, Tile type B1).A 3-dimensional finite element model of PSD was simulated using 5 implants, including single superior plate (Single-Plate), superior and anterior plate (Dual-Plate), single cannulated screw (Single-Screw), cro...

OBJECT Lumbar interbody fusion is indicated in the treatment of degenerative conditions. Laterally inserted interbody cages significantly decrease range of motion (ROM) compared with other cages. Supplemental fixation options such as lateral plates or spinous process plates have been shown to provide stability and to reduce morbidity. The authors of the current study investigate the in vitro st...

BACKGROUND Proximal humeral fractures are common lesions of the elderly, but there are no established treatment guidelines. A surgical treatment for comminuted and displaced fractures of the proximal humerus was developed and is still evolving. The aim of this study was to perform a quantitative review to evaluate the risk of avascular necrosis (AVN) in patients with proximal humeral fractures ...

BACKGROUND The aim of this study is to investigate the anatomic changes in the shoulder joints responsible for omalgia after the clavicular hook plate fixation under arthroscope. METHODS Arthroscopic examination was carried out for 12 omalgia patients who underwent clavicular hook plate fixation due to distal clavicle fractures. Functional outcome of shoulder was measured by the Japanese Orth...
