This study compares the functional capabilities of different metacarpal fixation constructs under physiological loadings in an attempt to identify the optimal construct rather than the strongest one. One hundred and twenty-six preserved human metacarpals were mechanically tested after oblique osteotomies and internal fixation. Maximum load to failure, average structural rigidity, and energ...

The relationship between spinal sagittal alignment and pelvic parameters is well known in adolescent idiopathic scoliosis. However, few studies have reported the sagittal spinopelvic relationship after selective posterior fusion of thoracolumbar/lumbar (TL/L) curves. We evaluated the relationship between spinal sagittal alignment and the pelvis, and analyzed how the pelvic sagittal state is adj...

Background: Adult degenerative disorders of hip and spine are common. The recent studies inconsistently havediscussed about the influence of spinal disorders on total hip arthroplasty (THA). In this review, we discussed clearlyabout these relationships and their effects on the most appropriate position of the acetabular component.Methods: We searched on databases and evaluated the articles abou...

Bisphosphonates have become the first-line treatment for diseases involving excessive osteoclast-mediated bone resorption. However, evidence suggests that elevated doses or prolonged treatment may impair normal skeletal mineralization and may be associated with fractures. The majority of these fractures are located in the subtrochanteric region. This article presents the first described case of...

Objective One of the unexplained, but well known, characteristics of AIS is that girls are far more often affected than boys and the initiation and progression of the deformity normally occurs around the adolescent growth spurt. From previous studies it can be inferred that, due to biomechanical forces that act on posteriorly inclined spinal segments, certain sagittal spinal profiles are more p...

Methods 64 consecutive PD patients were included: 53 males, 11 females; 69.5±8.1 years; 5.6±4.1 years of disease (YOD); Hoehn Yahr (H&Y) 2.4±1.1, UPDRS-M 16.1±12.5. The clinical assessment included HY and UPDRS-M score, Pain NRS 0-10 and trunk rotation in bending (ATR). Lumbar lordosis (LL), thoracic kyphosis (TK), scoliosis curves (SC), spinosacral angle (SSA), spinopelvic angle (SPA), pelvic ...
