Surgical Treatment for Unstable Distal Clavicle Fracture with Micromovable and Anatomical Acromioclavicular Plate

Between 2006 and 2009, 18 patients of distal clavicle fracture were treated with micro-movable and anatomical acromioclavicular plate (MAAP) in our department. According to the Neer's classification, all cases were unstable with type IIA (12 cases) and type IIB (6 cases). Functional outcome was evaluated using the Karlsson's criteria. The mean follow-up was 18 months (range, 12-36months). No postoperative plate screws complication was observed. Osseous union could be achieved at a mean time of 12 weeks after operation in 18 patients (range, 8 -16 weeks). According to Karlsson's criteria, radiographic appearances and postoperative shoulder functional recovery revealed a good and excellent rate in these cases. We conclude that surgical treatment using MAAP seems to be a good option for unstable type II fractures of the distal clavicle. This technique allows for reliable fixation with early functional exercises and functional recovery

Wireless extension mechanism and logic design for FPGA-based Ethernet Powerlink node

Real-time networks, such as industrial network, field bus and so on, have been becoming one vital component to develop large-scale and cooperative embedded systems. As one important branch, the wireless mode of realtime networks also raises more and more attentions in recent years since its conveniences to construct a flexible control system. Ethernet Powerlink is such a typical real-time industrial network protocol, and provides a master-slave, time-slot mechanism that can well avoid radio collisions. With the designed FPGA-based hardware node, in this paper, a new method to extend wireless capability of Powerlink is explored and described. Concretely, Powerlink architecture and especially its original mechanisms are analyzed at first. For effectively connecting OpenMAC module of Powerlink and RF module, an interface logic at MAC layer is introduced and is typically designed in a multiplexing mode with a dual-FIFO logic according to the limited resource on FPGA, some key designs and mechanisms of which are detailed later. Finally, all designed mechanisms and logics are implemented as an extension part of IP core of Powerlink in VHDL language, and the communication functions and performance of such extended protocol areverified
