Radiographic Outcomes in Treatment of Thumb Basal Joint Arthritis: Does Interposition of Acellular Dermal Allograft Prevent Metacarpal Settling?

 Osteoarthritis at the thumb carpometacarpal joint can have a profound impact on quality of life. Here, we evaluate radiographic outcomes in patients who have had open complete trapeziectomy, ligament reconstruction with tendon interposition, and acellular dermal matrix (GraftJacket) interposition-Group A, and compare them with those without GraftJacket interposition-Group B.  Thirty patients who had undergone operative treatment for thumb basal joint arthritis by a single surgeon from 2009 to 2016 were identified, and charts were retrospectively reviewed for demographic data, surgical and radiographic outcomes, and complications.

Not all sagittal band tears come with extensor instability: a case report with radiological and operative correlation.

The sagittal bands are a component of the extensor hood. They serve an important role in stabilizing the extensor tendon by forming a "check-rein" to radial-ulnar translation of the tendon over the metacarpal head, and extending the metacarpophalangeal (MCP) joint by virtue of attaching the extensor tendon to the palmar plate. Injury to the sagittal band is thought to cause extensor instability and subluxation to the contralateral side by disruption of this "check-rein" function, although recent evidence from cadaver studies suggests that ulnar sagittal band tear may be spared of extensor instability.

Three-Dimensional Carpal Kinematics after Carpal Tunnel Release.

Background: Carpal tunnel release (CTR) has been shown to change carpal arch morphology. However, the effect of CTR on the three-dimensional kinematics of the carpal bones has not been demonstrated.

Purpose: This study examined whether release of the transverse carpal ligament (TCL) would alter the three-dimensional kinematics of the carpus, specifically the bony attachments of the TCL.

Stakeholder understandings of wildfire mitigation: a case of shared and contested meanings.

This article identifies and compares meanings of wildfire risk mitigation for stakeholders in the Front Range of Colorado, USA. We examine the case of a collaborative partnership sponsored by government agencies and directed to decrease hazardous fuels in interface areas. Data were collected by way of key informant interviews and focus groups.

Understanding the wicked nature of "unmanaged recreation" in Colorado's Front Range.

Unmanaged recreation presents a challenge to both researchers and managers of outdoor recreation in the United States because it is shrouded in uncertainty resulting from disagreement over the definition of the problem, the strategies for resolving the problem, and the outcomes of management. Incomplete knowledge about recreation visitors' values and relationships with one another, other stakeholders, and the land further complicate the problem. Uncertainty and social complexity make the unmanaged recreation issue a wicked problem.

Biomechanical and anatomical consequences of carpal tunnel release.

Carpal tunnel syndrome is an exceedingly common orthopaedic problem in the United States. When conservative management is unsuccessful, most surgeons proceed to surgical treatment. Though the carpal tunnel release procedure is usually curative, many patients experience postoperative complications, such as scar sensitivity, pillar pain, recurrent symptoms, and grip weakness, regardless of whether the release was done through an open, mini-open, or endoscopic approach.
