OBJECTIVE to assess the surgical technique using the modified palm open technique for the treatment of severe contractions of Dupuytren's disease. METHODS over a period of four years, 16 patients underwent surgical treatment, and in its entirety belonged to stages III and IV of the classification proposed by Tubiana et al. We performed measurements of the extension deficit of the metacarpopha...

Fractures of the proximal interphalangeal joint constitute a broad spectrum of injuries. An understanding of the anatomy, the potential for joint instability, and the treatment options is essential to management of these fractures. Commonly observed fracture patterns involve one or both condyles of the proximal phalanx or the base of the middle phalanx. Fractures of the middle phalanx may invol...

We set limits on the configuration space of the pose parameters in order to automatically generate realistic hand poses using our 3D synthetic hand model. This ensures natural hand configurations mimicking real hand gestures. A comprehensive study on the functional ranges of joint movement is conducted in [3] and [2]. We employ the Type I and II constraints articulated in these papers on our ki...

Fracture-dislocations in the small joints of the fingers are challenging injuries. The surgeon must choose an appropriate treatment based on fracture pattern, joint stability, and injury chronicity. Fracture-dislocations of the proximal interphalangeal joint are notoriously unforgiving, with potential long-term sequelae of residual pain and stiffness. Similar injuries in the distal interphalang...

Dupuytren's disease is a progressive condition that causes the fibrous tissue of the palmar fascia to shorten and thicken. The disease is common in men older than 40 years; in persons of Northern European descent; and in persons who smoke, use alcohol, or have diabetes. Patients present with a small, pitted nodule (or multiple nodules) on the palm, which slowly progresses to contracture of the ...

The aim of the study was to investigate the influence of a preceding flexion or extension movement on the static interaction of human finger flexor tendons and pulleys concerning flexion torque being generated. Six human fresh frozen cadaver long fingers were mounted in an isokinetic movement device for the proximal interphalangeal (PIP) joint. During flexion and extension movement both flexor ...
