Femoral tunnel intersection in combined anterior cruciate ligament and posterolateral corner reconstruction has been reported to be high. The purpose of this study was to examine the risk of intersection between an anatomic femoral anterior cruciate ligament tunnel created with a retrograde reaming device and femoral lateral collateral ligament reconstruction tunnels of varying trajectory in a ...

Osteocutaneous thermonecrosis is a rare but devastating complication of tibial reaming, which can cause large and infected bone and cutaneous defects. The case presented here illustrates that the induced membrane technique described by Masquelet is a valuable option in treating this complication.

Carbon fiber-reinforced plastic/titanium alloy (CFRP/Ti) stacks are widely used in the aerospace field based on their high strength to weight ratio and heat resistance. High-quality bolt hole assembly is critical for safety of industry. Reaming a crucial process precision machining extensively improve quality holes. Due different properties material, with conventional reaming (CR) presents some...

The paper proposes a new technology for fluid production intensification, in particular hydrocarbons, which is implemented via significant increasing of the local wellbore diameter interval, where productive stratum present. proposed improves well productivity by filtration surface area and opening channels filtering fluids into well. innovative, technical idea to drill large circular recesses ...

Horizontal directional drilling (HDD) is widely used in soil and rock engineering. In a variety of conditions, it is necessary to estimate the torque required for performing the reaming operation. Nevertheless, there is not presently a convenient method to accomplish this task. In this paper, to overcome this difficulty based on the basic concepts of rock engineering systems (RES), a model for ...
