STUDY DESIGN In an in vivo sheep model, the effects of spinal fusion and kyphotic deformity on the neighboring motion segments were analyzed. OBJECTIVES To investigate the effects of spinal fusion and kyphotic deformity on the adjacent motion segment. SUMMARY OF BACKGROUND DATA The in vivo effects of kyphotic deformity on the neighboring motion segments have not been investigated in any stu...

OBJECTIVES The aim of the current study was to analyse the effects of posterior cruciate ligament (PCL) deficiency on forces of the posterolateral corner structure and on tibiofemoral (TF) and patellofemoral (PF) contact force under dynamic-loading conditions. METHODS A subject-specific knee model was validated using a passive flexion experiment, electromyography data, muscle activation, and ...

BACKGROUND The diagnosis of posterolateral instability of the knee is often based on a typical indirect mechanism of injury, a history of "giving way" and a positive dial test. Our search of the English literature revealed no mention of including the valgus stress test in the diagnostic protocol for posterolateral instability. HYPOTHESIS Based on our experience, we hypothesised that a medial ...

The objective of the present study was to evaluate the clinical, radiological, and functional outcomes of a subscapularis transthoracic surgical approach and a posterolateral surgical approach with debridement, bone graft fusion, and internal fixation for the treatment of upper thoracic tuberculosis.There is currently debate over the best surgical approach for the treatment of upper thoracic tu...

OBJECTIVE The wisdom of surgery facing multiple and multi-focal ribs fractures (flail segment) remains controversial. By the present retrospective study, we sought to determine the advisability of surgery as well as the anatomical and biomechanical features of flail segment leading to secondary dislocation. METHOD From 1970 to 2000, 127 patients underwent flail segment osteosynthesis. Clinica...

sclerosing hemangioma of the lung is extremely rare.  herein, a case of sclerosing hemangioma of the lung in a 44-year-old woman is reported.  on admission, the patient complained of pain in the left lower neck and upper chest.  chest x-ray revealed a mass in lingular lobe of the left lung.  the patient underwent surgery and a mass was removed through left posterolateral thoracotomy.  pathologi...

BACKGROUND Trinity Evolution® cellular bone allograft (TE) possesses the osteogenic, osteoinductive, and osteoconductive elements essential for bone healing. The purpose of this study is to evaluate the radiographic and clinical outcomes when TE is used as a graft extender in combination with locally derived bone in one- and two-level instrumented lumbar posterolateral arthrodeses. METHODS In...
