BACKGROUND There are two surgical approaches for distal soft-tissue procedures for the correction of hallux valgus-the dorsal first web-space approach, and the medial transarticular approach. The purpose of this study was to compare the outcomes achieved after use of either of these approaches combined with a distal chevron osteotomy in patients with moderate to severe hallux valgus. METHODS ...

Background In recent years, joint-preserving surgery has become common surgical procedure for forefoot deformities in Japanese patients with rheumatoid arthritis (RA). Since contributes to hallux valgus deformity RA, the postoperative outcome may differ from that idiopathic (IHV) patients. Objectives this study, we compared results of Mitchell’s osteotomy RA and IHV. Methods We evaluated 181 fe...

Background: Hallux valgus is a complex deformity and although not common but difficult to treat .It started from first row then involve the entire foot. There are many surgical techniques this problem. Both soft tissue procedures bony osteotomies mentioned in literatures still there no any gold standard. We used tissues procedure cheveron osteotomy for treatment. Coughlin classification was ass...

Useful lifetime evaluation of chevron rubber spring was very important in design procedure to assure the safety and reliability. It is, therefore, necessary to establish a suitable criterion for the replacement period of chevron rubber spring. In this study, we performed characteristic analysis and useful lifetime prediction of chevron rubber spring. Rubber material coefficient was obtained by ...

This report describes key aspects of a code library that we developed for the purpose of state propagation for business process monitoring on different levels of abstraction. The library supports the propagation of execution states of process instances based on the Business Process Execution Language (BPEL) to process models specified in the “Chevron” language. The Chevron language is an abstra...

An experimental investigation was performed of the acoustic effects of jet-pylon interaction for separate flow and chevron nozzles of both bypass ratio five and eight. The models corresponded to an approximate scale factor of nine. Cycle conditions from approach to takeoff were tested at wind tunnel free jet Mach numbers of 0.1, 0.2 and 0.28. An eight-chevron core nozzle, a sixteen chevron fan ...
