BACKGROUND The aim of this study was to assess total femur replacement for the treatment of femoral osteosarcomas. METHODS Between January 1995 and January 2012, 21 patients with a mean age of 21.8 years old were treated for femoral osteosarcomas with total femur replacement. All tumors were staged according to Enneking's criteria with one stage IIA case and 20 stage IIB cases. RESULTS The ...

As a result of deficiency at birth, disease or trauma, there are people who have no limbs from the hip joint downwards. These people have no possibility of locomotion without the use of other devices such as wheelchairs or hip disarticulation prostheses. As these prostheses are used by people of all ages, people who are different in their grade of physical activities and their weights, the pros...

230 INTRODUCTION The main goals of the Revolutionizing Prosthetics (RP) effort focus on the development of high-dexterity upper-limb prostheses and controlling the prostheses by decoding signals expressing the intent of a prosthesis user. The injury suffered by the prosthesis user ultimately defines the source of these biological signals. For example, long transradial amputation patients (a bel...

In this paper the author offers a phenomenology and a metapsychology for the effects on the mind of catastrophic psychic trauma, defined as the reaction of the psyche to an utterly external event, which the person is helpless to resist, and against which there is no possible defense. The author affirms that the experience of 'infinite affliction' produces a radical break in being which disartic...

We conducted an experimental study of the timing and nature of taphonomic processes in turtles that allowed a comparison among different environments. We documented decay and disarticulation of freshly-killed aquatic turtles in controlled settings, including freshwater and seawater aquaria, and outdoor terrestrial settings protected from scavengers. The study area was in hot and dry southern Ca...

Although the majority of teleost fishes possess a fused lower jaw (or mandible), some lineages have acquired a secondary joint in the lower jaw, termed the intramandibular joint (IMJ). The IMJ is a new module that formed within the already exceptionally complex teleost head, and disarticulation of two bony elements of the mandible potentially creates a "double-jointed" jaw. The apparent indepen...
