INTRODUCTION Although osteoarthritis (OA) commonly involves multiple joints, no widely accepted method for quantifying whole-body OA burden exists. Therefore, our aim was to apply factor analytic methods to radiographic OA (rOA) grades across multiple joint sites, representing both presence and severity, to quantify the burden of rOA. METHODS We used cross-sectional data from the Johnston Cou...

OBJECTIVE The aim of this study was to determine if thumb motor performance metrics varied by movement orientation, direction, and device size during single-handed use of a mobile phone device. BACKGROUND With the increased use of mobile phones, understanding how design factors affect and improve performance can provide better design guidelines. METHOD A repeated measures laboratory experim...

INTRODUCTION Thumb carpometacarpal osteoarthritis is a common and disabling disorder that affects 15% of adults over the age of 30, and 66% of women over the age of 55.1 Thumb use is affected by pain, weakness and loss of dexterity, leading to significant impairment (40%-50%)2 of the upper extremity due to its central role in nearly all grasp and handling maneuvers. Since Kellgren and Lawrence’...

INTRODUCTION Used routinely in maxillofacial reconstructive surgery, the chondrocostal graft is also used in hand surgery. The purpose of this overview was to analyze at long follow-up the radiological and histological evolution of this autograft, in the hand and wrist surgery. MATERIALS AND METHODS Since 1992, 144 patients have benefitted from a chondrocostal autograft: 116 osteoarthritis of...

PURPOSE To report results on 144 cases following arthroscopic resection arthroplasty (ARA) with or without interposition for basal joint arthritis. METHODS Cases undergoing ARA for thumb carpometacarpal osteoarthritis between 2004 and 2011 were prospectively enrolled (n = 178). Data were collected before surgery and after surgery at 1, 3, 6, and 12 months and annually thereafter. Patients wer...

This study determined flexion and extension angles of resting fingers and wrist in terms of forearm posture (neutral, pronation and supination) and shoulder flexion (0°, 45°, 90° and 135°). The participants participated in 12 angle measurements for 16 finger joints and wrist. The finger joints flexed more in supination than in neutral posture and pronation and the thumb flexed more than the oth...
