A vascularised bone-graft procedure from the base of the second metacarpal was performed in 14 patients with nonunion of the scaphoid. There were 11 men and three women with a mean age of 22 years. In eight patients, who had dorsiflexed intercalated segment instability (DISI), an open wedge was formed at the site of nonunion, and the vascular pedicle was grafted from the volar side. In the six ...

The re-establishment of vascularity is an early event in fracture healing; upregulation of angiogenesis may therefore promote the formation of bone. We have investigated the capacity of vascular endothelial growth factor (VEGF) to stimulate the formation of bone in an experimental atrophic nonunion model. Three groups of eight rabbits underwent a standard nonunion operation. This was followed b...

Humeral non unions are often painful and unstable Good surgical management is sometimes very difficult. Fixation with plates and screws and bone grafting may fail. The outcome of revision operation may be adversely affected by restricted movement of elbow. In most cases, the patient has been several times operated with resultant scarring and cicatrisation of the surrounding soft tissues. This r...

BACKGROUND The results for nonunion surgery usually have been judged in terms of bony union, time to union, infection rate, range of motion for the adjacent joints, and muscle strength. The goal of this study was to assess the improvement of patient-oriented physical and mental functional outcomes. METHODS The functional status of 23 patients with nonunion of the lower extremity was assessed ...

BACKGROUND The purposes of the present study are to evaluate the subsidence and nonunion that occurred after anterior cervical discectomy and fusion using a stand-alone intervertebral cage and to analyze the risk factors for the complications. METHODS Thirty-eight patients (47 segments) who underwent anterior cervical fusion using a stand-alone polyetheretherketone (PEEK) cage and an autologo...

This paper presents conflicting evidence on trends in private sector union and nonunion wages. The BLS quarterly Employment Cost Index (ECI), constructed from establishment surveys, uses fixed weights applied to wage changes among matched job quotes. The ECI shows a substantial decrease in wage growth for union relative to nonunion workers. The annual Employer Costs for Employee Compensation (E...

Introduction: Nonunion is found with an incidence of up to 15%, depending on the location fracture and a complicated problem significant long-term morbidity, both for anatomical functional results. In case manifest nonunion surgeon faces challenging problem. Fracture sometimes occurs after treatment, some patients are still difficult heal many times treatment. order more effectively treat recal...

INTRODUCTION Nonunion of femoral neck fractures frequently occurs in elderly patients. In patients with rheumatoid arthritis, reoperation rates after internal fixation of a displaced femoral neck fracture increase by up to 60 %. Revision surgery with arthroplasty is often preferred for nonunion of femoral neck fractures because there are few effective options for conservative treatment. Teripar...

Background. The aim of this study was to examine clinical and radiographic healing after rhBMP-2 application in children and adolescents presenting with nonunion of the femur and to investigate the safety of rhBMP-2 use in these cases. Materials and Methods. We reviewed the medical records of five patients with a mean age of 11 years (5.4 to 16.2) with nonunion of the femur who were treated wit...
