STUDY DESIGN Retrospective study. PURPOSE The main purpose of this study was to investigate the union-rate of the spinous process after performing a spinous process osteotomy and whether union affects the clinical results after surgery. OVERVIEW OF LITERATURE In the present study, spinous process osteotomy was used to facilitate access to the spinal canal when performing a decompressive pro...

The evolution of a fracture non-union is complex; treatment strategies are therefore challenging. The use of BMP-7 could be an interesting adjunct. We present an overview of the monitored use of this product in tibial non-unions in Belgium. Our retrospective data covers 53% (62 patients) of the cases in which it was used between 2001 and 2006. Questionnaires were sent to surgeons who had been u...

Background: Non-union of the femoral neck fracture in young and middle-aged patients is a problem and can be very debilitating. If the femoral head is viable, the most appropriate treatment is valgus osteotomy that without refreshing of the fracture site, it only increases the femoral neck angle to change shearing force to compression force. In this study, after refreshing the non-union site an...

In this paper, I study the wage differential between firms’ union representatives and their coworkers using a linked employer-employee dataset. On the employee side of the data, the surveyed workers are asked if they are unionized but we do not know which unionized workers are union representatives. On the employer side of the data, I have access to the number of union representatives and union...

  Abstract   Background: Fractures of the tibia are important for their commonness and controversy in their management. Both conservative and surgical techniques have been introduced in an effort to speed time to :::union::: while minimizing the occurrence of complications. Standard treatment for low-energy tibial shaft fractures includes closed reduction and cast immobilization. The purpose of...

Background: Distal tibia fractures are among the most common bony injuries, with a significant rate of nonunion anddelayed union. There are multiple methods for the management of distal tibia fractures. Among the plating methods,there are bridge plating and compression plating techniques. There is still a lack of evidence about whether one methodhas a higher rate of union than...

Fracture non-union or delayed union frequently occur after high-energy traumas associated to significant bony tissue loss, in open fractures with infections, and after an inappropriate use of internal fixation.1,2,3,4,5,6,7 Obesity, smoking, abuse of alcohol or drugs, osteoporosis and immunodepression are additional factors that prevent bone healing.1,4,6 Based on characteristic of the bone end...
