AIMS The aim of this study was to describe the morphological features of posterolateral radiohumeral (RH) plica in asymptomatic subjects and in patients with elbow osteoarthritis using ultrasonography (US). MATERIAL AND METHODS The control group included a total of 100 healthy elbows (51 subjects) and the study group consisted of 22 elbows (22 patients) with osteoarthritis confirmed clinicall...

BACKGROUND Lateral column tibial plateau fracture fixation with a locking screw plate has higher mechanical stability than other fixation methods. The objectives of the present study were to introduce two newly designed locking anatomic plates for lateral tibial plateau fracture and to demonstrate their characteristics of the fixation complexes under the axial loads. METHODS Three different 3...

Treatment of posterolateral tibial plateau fractures is controversial, and information regarding this specific fracture pattern is lacking. The purpose of this study was to elucidate the frequency and morphological features of posterolateral articular fragments in tibial plateau fractures. A retrospective radiographic and chart review was performed on a consecutive series of patients who sustai...

OBJECTIVE To test the hypothesis that the head kinematic and the cervical muscle EMG responses to unexpected impacts of increasing low-velocity in the posterolateral direction will be greater than to expected impacts. DESIGN Ten healthy volunteers were subjected to right posterolateral of 5.0, 8.6, 12.2, and 15.4 m/s2 acceleration in expected and unexpected conditions. BACKGROUND The effect...

Congenital Lumbar spinal stenosis (LSS) defined first by Dr. Sarpyener in 1940’s17, and degenerative LSS was defined by Verbiest in 1950’s.19 Degenerative LSS can be classified as simple or complex LSS, depending on the presence or absence of attendant pathologies. LSS can also be classified on axial plane as central, lateral, or foraminal. LSS may result inneurogenic claucation or radiculopath...

Posterolateral fusion has long been considered the "gold standard" technique for surgical treatment of adult spondylolisthesis. Superior results have subsequently been reported with interbody fusion with cages and posterior instrumentation. The goal of this prospective study was to compare the two techniques regarding their clinical outcomes and fusion rates. Fifty-two patients with isthmic spo...

Seventy-one consecutive patients with posterolateral knee injuries had clinical stability testing abnormalities documented prospectively. We compared these findings with the incidence and patterns of their injuries documented at surgery. An abnormal reverse pivot shift test was associated with injury to the fibular collateral ligament (P = 0.01), popliteal components (P = 0.01), and midthird la...
