The influence of foot geometry on the calcaneal osteotomy angle based on two-dimensional static force analyses.
Malalignment of the hindfoot can be corrected with a calcaneal osteotomy (CO). A well-selected osteotomy angle in the sagittal plane will reduce the shear force in the osteotomy plane while walking. The purpose was to determine the presence of a relationship between the foot geometry and loading of the calcaneus, which influences the choice of the preferred CO angle. ⋯ Foot geometry, in particular the relative foot heights is a determinant for the individual angle in performing the sliding calcaneal osteotomy. It is recommended to take into account the foot geometry (arch) when deciding on the CO angle for hindfoot correction.

Comparative StudyComparison of stability in the operative treatment of pelvic injuries in a finite element model.
The comparison of the stability of four surgical methods for the treatment of vertically and rotationally unstable type C pelvic ring injuries. ⋯ The finite element model may be utilized for the comparison of different methods of osteosynthesis for the treatment of injuries described above. Due to several difficulties in investigations performed on cadaver specimens, this model has undoubted utility.

ReviewReamed intramedullary nailing versus unreamed intramedullary nailing for shaft fracture of femur: a systematic literature review.
Fractures of femoral fracture are among the most common fractures encountered in orthopedic practice. Intramedullary nailing is the treatment choice for femoral shaft fractures in adults. The objective of this article is to determine the effects of reamed intramedullary nailing versus unreamed intramedullary nailing for fracture of femoral shaft in adults. ⋯ Reamed intramedullary nailing has better treatment effects than unreamed intramedullary nailing for shaft fracture of femur in adults.

Thoracic curve correction after posterior fusion and instrumentation of structural lumbar curves in patients with adolescent idiopathic scoliosis.
Spontaneous thoracic curve correction may occur following selective anterior spinal fusion in patients with adolescent idiopathic scoliosis (AIS). However, a few reports have described outcomes in patients following selective posterior fusion. The aim of this retrospective study was to assess curve correction in AIS patients with major lumbar curves and secondary thoracic curves after selective posterior fusion of the major curve. ⋯ Selective posterior fusion with segmental pedicle screw fixation in patients with major lumbar AIS resulted in curve correction in the majority of cases. Preoperative thoracic curvature and thoracic curvature on lateral bending were strongly correlated with the final thoracic curvature.

Fragility fractures are a major health care problem worldwide. The proportion of the geriatric population and the overall life expectancy will increase. Hip fractures are the most common fragility fractures needing surgery and nowadays treatment concepts are changing. We studied the long-term functional outcome and their influencing factors in patients treated without any interdisciplinary aspects. ⋯ This paper shows the frustrating long-term outcome of geriatric hip fracture patients but it also suggests that an early geriatric intervention may lead to better function.
