In adolescents and young adults, femoral neck fractures often result from high-velocity trauma. These fractures are usually of vertical shear pattern. There is an increased incidence of avascular necrosis and non-union, which is difficult to treat. Non-union of fractured neck of femur in young adults is a serious problem. There is growing evidence that these fractures should be treated with an ...

Introduction Non-union of femur fracture is a known complication, managed by various methods, including exchange nailing. Additional bone grafting is known to enhance fracture healing. Percutaneous bone grafting has been reported for tibia and humerus in the literature. The authors report a series of aseptic non-union of the femoral shaft managed by exchange nailing, supplemented with percutane...

The authors use British workplace data for 1980-98 to examine whether increased human resource management (HRM) practices coincided with union decline, consistent with the hypothesis that such practices act as a substitute for unionization. Two initial analyses show no important differences between union and non-union sectors or between newer workplaces (which are likelier to be non-union) and ...

The aim of this study was to assess the results of percutaneous injection of autologous bone marrow in the treatment of fractures presenting with delayed union or non union after internal fixation. Twenty consecutive patients presenting to our outpatient clinic with internally fixed fractures with delayed union or non union were included in the study. The time between the index surgery and the ...

Sternal non-union is a severe complication of sternotomy closure following open heart surgeries. Healing problems typically occur in 0.3% to 5% of patients. Technetium-99m methylene diphosphonate (99mTc-MDP) bone scintigraphy has been used to assess bone nonunion to predict the healing response for proper management.  In this report, we present the case of a marked sternal nonunio...

Retrospective radiographic analysis.To determine the fusion rate of stand-alone lateral lumbar interbody fusion (LLIF). Biomechanical studies have indicated that LLIF may be more stable than anterior or transforaminal lumbar interbody fusion. Early clinical reports of stand-alone LLIF have shown success in obtaining fusion and indirectly decompressing nerve roots. A consecutive case series of s...

PURPOSE To compare the treatment outcome of Acutrak versus Herbert screw fixation for scaphoid non-union and delayed union. METHODS Records of 132 patients who underwent Herbert screw fixation (n=61) or Acutrak screw fixation (n=71) with or without bone grafting for scaphoid non-union and delayed union by a single surgeon were reviewed. The most common fracture site was the waist of the scaph...

The purpose of this study was to identify the feature genes that are associated with non-union skeletal fractures using samples of normal union and non-union skeletal fracture microarray data. The gene expression profile GSE494 was downloaded from the Gene Expression Omnibus database and included 12 samples based on three different platforms (GPL92, GPL93 and GPL8300). Each of the platforms had...
