OBJECTIVE To study the effectiveness, advantages, disadvantages and failure rates of closed intramedullary interlocking nailing of daiphyseal fractures of the femur in adults. MATERIALS AND METHODS A total of 30 cases of diaphyseal femur fractures in adults, who have been treated with closed intramedullary interlocking nailing were studied from 2008 - 2010. Data was analyzed both with regards...

Methods: We conducted a multicenter, blinded randomized trial of 1319 adults in whom a tibial shaft fracture was treated with either reamed or unreamed intramedullary nailing. Perioperative care was standardized, and reoperations for nonunion before six months were disallowed. The primary composite outcome measured at twelve months postoperatively included bone-grafting, implant exchange, and d...

Introduction: Press-fit acetabular components are susceptible to deformation following implantation in an under-reamed socket, with excessive deformation of metal-on-metal (MOM) components potentially leading to increased torsional friction, component micromotion and implant loosening. The purpose of this study was to evaluate the effect of design and material considerations on induced deformat...

The effect of different methods of preparation of glenoid bone on displacement and deformation of a glenoid component under eccentric loading was investigated in a series of scapulae of cadavera. Handburring of the osseous surface was associated with less displacement and deformation than simple removal of cartilage with a curet. Reaming resulted in the least displacement and deformation. Subst...

In the present work, the edge stretchability of advanced high strength steel (AHSS) was investigated experimentally and numerically using both a hole expansion test and a tensile specimen with a central hole. The experimental fracture strains obtained using the hole expansion and hole tension test in both reamed and sheared edge conditions were in very good agreement, suggesting the tests are e...

Reaming of the long bones is widely practiced because it allows for improved healing and early mobilization in patients needing surgical debridement of bone tissue. The insertion of reamed intramedullary nails can cause complications such as bone necrosis, cortical blood supply damage, and fat or bone marrow embolism. We describe a novel way to limit the amount of material in the canal before n...

Nailing of tibial shaft fractures is considered the gold standard surgical method by many surgeons. The aim of this retrospective study was to investigate and compare the clinical outcome of tibial shaft fractures treated with intramedullary nails compressed by proximal tube and conventional intramedullary interlocking nails. Fifty-seven patients with tibial shaft fractures, treated with intram...

The Mohr-Coulomb theory of strength identifies cohesion and internal friction as the two principal contributions to the shear strength of a granular material. The contribution of cohesion in over-compacted granular materials has been challenged and replacing cohesion with interlocking has been proposed. A theory of rupture strength that includes interlocking is derived herein. The physics-chemi...
