Numerous modifications in nail and screw design have led to the development of the Expert Tibial Nail. It enables the surgeon to further extend the spectrum of fractures eligible for intramedullary nailing. In the proximal metaphysis spongious bone screws achieve an optimized purchase in the cancellous bone. Multidirectional interlocking screws ensure that alignment can be well maintained and s...

Wetting of actual surfaces involves diverse hysteretic phenomena stemming from ever-present imperfections. Here, we clarify the origin of wetting hysteresis for a liquid front advancing or receding across an isolated defect of nanometric size. Various kinds of chemical and topographical nanodefects, which represent salient features of actual heterogeneous surfaces, are investigated. The most pr...

BACKGROUND This study was undertaken to determine whether alveolar dead space increases during intramedullary nailing of femoral shaft fractures and whether alveolar dead space predicts postoperative pulmonary dysfunction in patients undergoing intramedullary nailing of a femoral shaft fracture. METHODS All patients with a femoral shaft fracture were prospectively enrolled in the study unless...

We performed a prospective randomised trial on matched groups of patients with displaced tibial shaft fractures to compare conservative treatment with closed intramedullary nailing. The results showed conclusively that intramedullary nailing gave more rapid union with less malunion and shortening. Nailed patients had less time off work with a more predictable and rapid return to full function. ...

is challenging owing to the relatively high chance of displacement during nail insertion. The stability of the proximal fixation is inferior because of the wider diameter of the intramedullary canal in the metaphysis. This has led to the use of Poller screws for additional blocking during intramedullary fixation of proximal or distal tibial fractures.1 The effects of Poller screw is two-fold. F...

abstract  background: reamed interlocking intramedullary nailing of the tibia is a procedure  for the treatment of a non-infected tibial non::::union::::. the purpose of this clinical  study was to evaluate the outcome of this method as a treatment of tibial non::::union::::.  methods: twenty-nine patients with non::::union:::: after initial therapy for tibial fracture  were retrospectively ass...

PURPOSE To systematically evaluate the clinical efficacy of reamed and nonreamed intramedullary nailing in treatment of closed tibial fractures with Cochrane systematic review methods. METHODS According to the Cochrane systematic review methods, literatures were retrieved from Cochrane library, PubMed, EMbase and other database. Randomized controlled trials (RCTs) and quasi-randomized control...

BACKGROUND AND PURPOSE It is not known whether there is a difference in bone healing after external fixation and after intramedullary nailing. We therefore compared fracture healing in rats after these two procedures. METHODS 40 male rats were subjected to a standardized tibial shaft osteotomy and were randomly assigned to 2 treatment groups: external fixation or intramedullary nailing. Evalu...
