PURPOSE The objectives of this study were (1) to compare locations of the femoral tunnels created by outside-in and transtibial techniques and the reference data and (2) to compare the diameter of the tunnel entrance based on the real reaming size. METHODS A comparative study was performed with 20 outside-in and 22 transtibial double-bundle anterior cruciate ligament reconstruction patients. ...

We have carried out a prospective, randomised trial to measure the rise of temperature during reaming of the tibia before intramedullary nailing. We studied 34 patients with a mean age of 35.1 years (18 to 63) and mean injury severity score of 10 (9 to 13). The patients were randomised into two groups: group 1 included 18 patients whose procedure was undertaken without a tourniquet and group 2,...

We have undertaken a prospective study in patients with a fracture of the femoral shaft requiring intramedullary nailing to test the hypothesis that the femoral canal could be a potential source of the second hit phenomenon. We determined the local femoral intramedullary and peripheral release of interleukin-6 (IL-6) after fracture and subsequent intramedullary reaming. In all patients, the fra...

Internal fixation is a widely used treatment method to repair bone fracture, which is one of the most common orthopedic trauma. However, in reaming of the intramedullary canal to facilitate insertion of a guiding rod by creating a surgical passage, severe disturbances such as increased local cortical temperature and elevation of intramedullary pressure can occur. These disturbances have resulte...

Prophylactic intramedullary fi xation of impending pathologic fractures is an important preventative technique. Intramedullary rods provide longitudinal structural support, protecting weakened cortices from fracture displacement, providing pain relief, and allowing for restoration of function.1,2 In the femur, prophylactic stabilization of an impending fracture in a metastatic tumor population ...

We assessed factors which may affect union in 32 patients with nonunion of a fracture of the diaphysis of the femur and 67 comparable patients whose fracture had united. These included gender, age, smoking habit, the use of non-steroidal anti-inflammatory drugs (NSAIDs) the type of fracture (AO classification), soft-tissue injury (open or closed), the type of nail, the mode of locking, reaming ...

CRACKING THE SCLEROTIC BONE RIM COMPARED TO REAMING +*Elmengaard, B; **Bechtold, JE; *Baas, J; Jakobsen, T; *Søballe, K +*Department of Orthopaedic Surgery, University of Aarhus, Denmark [email protected] INTRODUCTION Revision hip replacement implants have poorer clinical outcome than primary implants. The fixation of the implants is often compromised by the formation of an endosteal scleroti...

The reproducibility of a reaming test was analysed to document its applicability as a performance test for cutting fluids. Reaming tests were carried out on a drilling machine using HSS reamers. Workpiece material was an austenitic stainless steel, machined using 4.75 m·min cutting speed and 0.3 mm·rev feed. A mineral straight oil and a water-based lubricant at two different oil concentrations ...

The relationship between BMP2 expression and the recruitment of skeletogenic stem cells was assessed following bone marrow reaming. BMP2 expression was examined using transgenic mice in which β-galactosidase had been inserted into the coding region of BMP2. Stem cell mobilization was analyzed by FACS analysis using CD73, a marker associated with bone marrow stromal stem cells. BMP2 expression w...
