INTRODUCTION The aim of this study was to examine resistance to angulation and displacement of the internal fixation of a proximal first metatarsal lateral displacement osteotomy, using a locking plate system compared with a conventional crossed screw fixation. MATERIALS AND METHODOLOGY Seven anatomical human specimens were tested. Each specimen was tested with a locking screw plate as well a...

The diaphyseal tibia fracture is best treated with intramedullary nail but in some cases where the nail is not applicable, plate fixation will be the next option of fixation. The extensile anterior approach is normally used for conventional compression plate fixation in tibia shaft fractures. The extensive surgical dissection may devitalizes the bony fragments and interfere with the fracture un...

Higher rates of poor outcomes in displaced midshaft clavicle fractures treated nonoperatively have recently been reported. Along with expanding indications for operative fixation and increasing application of locked plate constructs, it is unknown whether complications related to bicortical penetration of the clavicle can be avoided using unicortical fixation. The purpose of this study is to co...

BACKGROUND The objective of this study was to determine whether one can achieve stable fixation of a two column (transverse) acetabular fracture by only fixing a single column with a locking plate and unicortical locking screws. We hypothesized that a locking plate applied to the anterior column of a transverse acetabular fracture would create a construct that is more rigid than a non-locking p...

Open reduction and internal fixation has been shown to be effective in the treatment of unstable distal radius fractures. When a dorsal approach is used, extensor tendons rupture or irritation are frequent and well known complications. Complications associated with volar plate fixation have not been studied to the same extent. In this study a homogenous series of 90 patients treated by volar pl...

BACKGROUND The purpose of this study was to determine whether additional tension band wiring in the plate for traumatic disruption of symphysis pubis has clinical benefits. Therefore, outcomes and complications were compared between a plate fixation group and a plate with tension band wiring group. METHODS We retrospectively evaluated 64 consecutive patients who underwent open reduction and i...

PURPOSE To evaluate the fixation strength at the interface between the Kerboull-type plate and bone cement in 6 experimental conditions. METHODS Experimental materials comprised a simulated acetabular block, a simulated Kerboulltype plate, a pressuriser cover, a pressuriser arm, and bone cement. The simulated Kerboull-type plate was placed on the simulated acetabular block, with the pressuris...

PURPOSE Anterior plate fixation has been reported to provide satisfactory results in cervical spine distractive flexion (DF) injuries stages 1 and 2, but will result in a substantial failure rate in more unstable stage 3 and above. The aim of this investigation was to determine the biomechanical properties of different fixation techniques in a DF-3 injury model where all structures responsible ...

PURPOSE To compare the results of staple versus locking compression plate fixation after closing wedge high tibial osteotomy. METHODS A group of 23 patients (24 knees) who underwent box high tibial osteotomy and staple fixation was compared with another group of 19 patients (22 knees) who underwent a similar procedure but with locking compression plate fixation. Both groups were followed up f...

Although clavicle fractures often heal well with nonoperative management, current literature has shown improved outcomes with operative intervention for specific fracture patterns in specific patient types. The 2 most common methods of midshaft clavicle fracture fixation are intramedullary and plate devices. Through retrospective analysis, this study performed a direct cost comparison of these ...
