PURPOSE To investigate whether palmaris longus interposition or flexor carpi radialis ligament reconstruction and tendon interposition improve the outcome of trapezial excision for the treatment of basal joint arthritis after a minimum follow-up of 5 years. METHODS We randomized 174 thumbs with trapeziometacarpal osteoarthritis into 3 groups to undergo simple trapeziectomy, trapeziectomy with...

Pain and loss of motion associated with elbow arthritis is poorly tolerated and constitutes a major functional impairment. While total elbow arthroplasty reliably alleviates pain and improves motion, durability issues mandate restricted indications and light use. Interposition arthroplasty, combined with hinged external fixation, is an alternative and may be preferred in younger, more active pa...

PURPOSE Tumor invasion to the portal vein (PV) or superior mesenteric vein (SMV) can be encountered during the surgery for pancreatic cancer. Venous reconstruction is required, but the optimal surgical methods and conduits remain in controversies. METHODS From January 2007 to July 2012, 16 venous reconstructions were performed during surgery for pancreatic cancer in 14 patients. We analyzed t...

Spatial organization of a chromosome in a nucleus is very important in biology but many aspects of it are still generally unresolved. We focused on tissue-specific features of chromosome architecture in closely related malaria mosquitoes, which have essential inter-specific differences in polytene chromosome attachments in nurse cells. We showed that the region responsible for X-chromosome atta...

PURPOSE We compared the effectiveness and complications associated with 2 common vasectomy occlusion techniques, namely clipping and excision of a small vas segment and thermal cautery with fascial interposition and an open testicular end. MATERIALS AND METHODS We retrospectively reviewed the computerized records of 3,761 men who underwent initial vasectomy at a single university hospital fam...

Modern production operating systems are large and complex systems developed over many years by large teams of programmers, containing many hundreds of thousands of lines of code. Consequently, it is extremely difficult to add significant new functionality to these systems [16, 1, 42]. In response to this problem, a number of recent research projects have addressed the issue of extensible operat...

BACKGROUND This study has been conducted with the aim of evaluating modified T-plate interpositional arthroplasty. METHODS A prospective comparative study in patients admitted with temporomandibular joint ankylosis. Ankylotic temporomandibular joint arthroplasty included condylectomy gap arthroplasty in 7, temporalis muscle flap interpositional arthroplasty in 8, and modified T-plate interpos...

Distributed computing continues to be an alphabet-soup of services and protocols for managing computation and storage. To live in this environment, applications require middleware that can transparently adapt standard interfaces to new distributed systems; such software is known as an interposition agent. In this paper, we present several lessons learned about interposition agents via a progres...
