We describe a new species of Anolis from the southeastern slopes of the Andes of Ecuador, province of Zamora-Chinchipe, Parque Nacional Podocarpus. It belongs to (1) the aequatorialis species-group by being of moderate to large size with narrow toe lamellae, and (2) the eulaemus sub-group by having a typical Anolis digit, in which the distal lamellae of phalanx II distinctly overlap the proxima...

Osteoid osteoma is a benign bone forming tumor of the growing skeleton that is most often seen in young men. It represents by pain and radiologic appearance of anidus surrounded by osteosclerosisthat occurs mostly in long bones of the lower extremity. Occurrence of this tumor in the hand is an uncommon condition. We present a 23-year-old man with an osteoid osteoma in the proximal phalanx of th...

A five-month-old, female Basset Hound was presented for lameness associated with a fused 3rd and 4th digital pad on the left hind limb (simple incomplete syndactyly), and secondary contracture of the deep digital flexure tendon of the 3rd and 4th digit. An onychectomy of the third phalanx of the third and fourth digits was performed. Following the operation, the dog gained good use of the affec...

The number of phalanges and joints are key features of digit 'identity' and are central to limb functionality and evolutionary adaptation. Prior chick work indicated that digit phalanges and their associated joints arise in a different manner than the more sparsely jointed long bones, and their identity is regulated by differential signalling from adjacent interdigits. Currently, there is no ge...

OBJECTIVE To compare the traditional two injections dorsal digital block with volar block in terms of effectiveness of anaesthesia and pain of initial pinprick. STUDY DESIGN Quasi-experimental. PLACE AND DURATION OF STUDY AVH and casualty operation theatres, Mayo Hospital, KEMU, Lahore, from January to June 2007. METHODOLOGY Thirty patients requiring surgical procedure distal to proximal ...

The Sunlight Omnisense is a portable quantitative ultrasound device that measures speed of sound (SOS) at multiple skeletal sites and therefore has the potential to provide a more complete assessment of an individual's overall fracture risk than single-site measurements such as the calcaneus. To provide a robust normative female database, 545 healthy Caucasian women ages 20-90 were recruited at...

An often overlooked aspect of digit development is the special nature of the terminal phalanx, a specialized structure with characteristics distinct from other phalanges, for example the presence of ectodermal derivatives such as nails and claws. Here, we describe the unique ossification pattern of distal phalanges and characteristic gene expression in the digit tips of chick and duck embryos. ...

Background: Dupuytren's disease is a benign fibroproliferative disorder that causes the fingers to be drawn into the palm via formation of new tissue under the glabrous skin of the hand. This disorder causes functional limitations, but it can be treated through a variety of surgical techniques. As a chronic condition, it tends to recur. Objectives: To assess the benefits and harms of different ...

Novel strategies are urgently required to facilitate regeneration of entire bones lost due to trauma or disease. In this study, we present a novel framework for the regeneration of whole bones by tissue engineering anatomically shaped hypertrophic cartilaginous grafts in vitro that subsequently drive endochondral bone formation in vivo. To realize this, we first fabricated molds from digitized ...

Thanks to the help of one ofmy pupils, a native of Madagascar, I was able to collect the following data concerning his own family (Fig.). Both parents are 'normal' and so are all uncles and aunts. The parents have 11 children, 5 boys and 6 girls. Among the children there are two dizygotic unlikesexed twins. Both twins have a fourth distal phalanx on their middle fingers. The female twin has no ...
