In this study, psychometric principles were used to develop an outcomes questionnaire capable of measuring health state domains important to patients with hand disorders. These domains were hypothesized to include (1) overall hand function, (2) activities of daily living (ADL), (3) pain, (4) work performance, (5) aesthetics, and (6) patient satisfaction(More)
PURPOSE Ulnar styloid fractures commonly occur with distal radius fractures (DRFs). Ulnar styloid fractures that involve the insertion of the radioulnar ligaments can cause distal radioulnar joint (DRUJ) instability, and the literature suggests that these fractures should be treated with open reduction internal fixation (ORIF). However, in the absence of(More)
Field Programmable Gate Arrays are new devices that combine the versatility of a Gate Array with the user-programmability of a PAL. This paper describes an algorithm for technology mapping of combinational logic into Field Programmable Gate Arrays that use lookup table memories to realize combinational functions. It is difficult to map into lookup tables(More)
PURPOSE As the population in developed countries continues to age, the incidence of osteoporotic distal radius fractures (DRFs) will increase as well. Treatment of DRF in the elderly population is controversial. We systematically reviewed the existing literature for the management of DRFs in patients aged 60 and over with 5 common techniques: the volar(More)
Distal radius fractures are one of the most common types of fractures. Although the pediatric and elderly populations are at greatest risk for this injury, distal radius fractures still have a significant impact on the health and well-being of young adults. Data from the past 40 years have documented a trend toward an overall increase in the prevalence of(More)
PURPOSE External fixation and open reduction and internal fixation have been the traditional techniques for surgical fixation of unstable distal radius fractures. The existing literature has not identified which is superior, primarily because of the lack of comparative trials. We performed a comprehensive systematic review and meta-analysis of the current(More)
PURPOSE Identifying predictors of outcomes is important in anticipating and treating patients with underlying factors that may affect recovery. The predictors of functional outcomes after distal radius fracture (DRF) treatment have not been well defined in the past. METHODS This was a prospective cohort study designed to identify predictors of hand(More)
BACKGROUND The best treatment for an inadequately reduced fracture of the distal part of the radius is not well established. We collected prospective outcomes data for patients undergoing open reduction and internal fixation of an inadequately reduced distal radial fracture with use of the volar locking plating system. METHODS Over a two-year period, 161(More)
Responsiveness is an important property of an outcomes questionnaire. It can be defined as the ability of an instrument to capture important changes in a patient's health status over time. The authors previously designed the Michigan Hand Outcomes Questionnaire (MHQ), a hand-specific outcomes instrument that contains six distinct scales: (1) overall hand(More)
PURPOSE The aim of this study was to demonstrate the validity and responsiveness of the Jebsen-Taylor Hand Function Test (JTT) in measuring hand function in patients undergoing hand surgery, compared with the Michigan Hand Outcomes Questionnaire (MHQ). METHODS A prospective cohort of patients with rheumatoid arthritis (n = 37), osteoarthritis (n= 10),(More)
