One of the major challenges, if not the major challenge, in the management of Dupuytren’s disease is correction of the proximal interphalangeal joint contracture and maintenance of this correction. In 1831 Dupuytren himself [1] recognized the difficulty in straightening the proximal interphalangeal joint. Despite this, much of the early literature focused on Dupuytren’s Disease in the palm [2]....

Few measurements have been made of the frictional forces within living joints. Barnett and Cobbold (1962) recorded that the coefficient of friction at the distal interphalangeal joint of the middle finger in six healthy adults could be as low as 0 0075, a figure of the same order as that in excised joints (Jones, 1936; Charnley, 1959). Rydell (1965) measured, in a patient fitted with a hip pros...

The role of the forearm (extrinsic) finger flexor muscles in initiating rotation of the metacarpophalangeal (MCP) joint and in coordinating flexion at the MCP, the proximal interphalangeal (PIP), and distal interphalangeal (DIP) joints remains a matter of some debate. To address the biomechanical feasibility of the extrinsic flexors performing these actions, a computer simulation of the index f...

background:  conventional treatments after complicated injuries of the distal radioulnar joint (druj) such as darrach and kapandji-sauvé procedures have many drawbacks, which may eventually lead to a painful unstable distal ulna.  the development of druj prosthesis has significantly evolved over the past years. in this study, we assessed the outcome results of patients after druj implant arthro...

We present a case of soft tissue chondroma arising from the soft tissues of the index finger of the right dominant hand. Although asymptomatic, the swelling gave rise to concern both for the patient and the hand surgeon. There was a relatively large osteoblastic lesion in relation to the volar aspect of the distal interphalangeal joint. The lesion was excised, the histological findings were tho...

BACKGROUND Digital myxoid cysts are a relatively common pathology in the skin, representing a ganglion of the adjacent distal interphalangeal joint. Success of treatment is largely proportional to the destructiveness of the therapy and postoperative morbidity. We studied an effective, minimally traumatic surgical treatment in which tissue is not removed and morbidity is low. DESIGN Open, nonr...

Bandoh reported the 3-square-flap method as a procedure for interdigital space reconstruction in patients with minor syndactyly. We recently modified this flap design so that it could be used in the treatment of toe syndactyly involving fusion of the areas distal to the proximal interphalangeal joint. With our method, the reconstructed interdigital space consists of 4 oblong flaps (A through D)...

Contact interactions between the hand and handle, such as the contact surface softness and contact surface curvature, will affect both physical effort and musculoskeletal fatigue, thereby the comfort and safety of power tool operations. Previous models of hand gripping can be categorized into two groups: multi-body dynamic models and finite element (FE) models. The goal of the current study is ...
