BACKGROUND Symptomatic Acromioclavicular (AC) dislocations have historically been surgically treated with Coracoclavicular (CC) ligament reconstruction with transfer of the Coracoacromial (CA) ligament. Tensioning the CA ligament is the key to success. METHODS Seventeen patients with chronic, symptomatic Type III AC joint or acute Type IV and V injuries were treated surgically. The distal cla...

• 3D concrete printing and structural testing of nine reinforced beams. Aligned interlayer fibres steel cables as shear reinforcement. Full-field digital image correlation precise analysis crack kinematics. Development a mechanical model for reinforcement in printed (3DCP) offers many new possibilities. This technology could increase the productivity construction industry reduce its environment...

Abstract The noncircular synchronous belt drive mechanism has demonstrated certain achievements and been used in special fields. Research regarding mechanisms focused on optimization design kinematic analysis China, whereas two pulley transmissions have developed overseas. However, owing to the characteristics of pulley, real-time variation length slack during transmission is significant, resul...

Background: The medial ulnar collateral ligament (MUCL) is the primary restraint to valgus force on elbow. Since first description of MUCL reconstruction by Jobe et al in 1986, many technical advancements have been implemented improve outcomes and reduce complications. docking technique has emerged as one most commonly used techniques. Indications: Following repetitive stress elbow during overh...

Canaloplasty is a new nonperforating glaucoma operation, which utilizes the experience with viscocanalostomy and adds a further surgical step to keep the ostia open and to stretch the trabecular meshwork permanently. During the operation, a deep sclerectomy and viscocanalostomy are performed as described by Stegmann et al. After this, a 200-2m microcatheter (iTrack; iScience Surgical Corp, Menl...

This paper investigates the applicabilty of an innovative bracing, called Articulated Quadrilateral (AQ) bracing system, which uses shape memory alloys (SMAs), for retroffiting low-rise to high-rise vulnerable SMFRs against strong ground motions. The paper investigates brace fundamental engineering characteristics, design of the system and also configuration of the brace (the proportion of SMA ...
