finger prints of 68 patients with down's syndrome and 93 controls have been collected and analyzed for topological of formulation of finger tip patterns suggested by loesch (1975). the results showed that there may be great differences in the dictionary of the finger patterns of the patients and their controls. mean lunar and radial patterns showed mostly significant differences among the patie...

abstract  background: the goal of this report is to show our results with extension block technique for treatment of mallet fracture. the indications for this technique were the presence of a large bone fragment, and palmar subluxation.  methods: we retrospectively assessed the results of treatment in 14 mallet fractures  which have been treated by extension block technique to determine the ran...

we present two patients with a displaced fracture of the small finger metacarpal base, where the shaft of the small finger metacarpal was wedged between the bases of the ring and small finger metacarpals. the striking appearance on radiographs led to initial recommendations for surgery, but both patients preferred non-operative treatment and did well in the short term without surgery

osteoid osteomata are rarely found in the distal phalanges of the hand. the usual presenting features are chronic pain, nail enlargement and increase in size of the terminal part of the digit. diagnosis is difficult but surgical excision is effective for treating the patients’pain. we reported this tumor in distal phalanx of the middle finger.

Introduction: Hand and wrist stability are critical for optimal upper extremity function. Instability occurs when injury or a pathological condition alters balance, typically in the basketball players and handball players. Injury also can occur whenever the ligaments are subjected to tensile forces that exceed their physiological capacities. For example, thumb is stable in ext...

Brain-machine interface (BMI) is the latest solution to a lack of control for paralyzed or prosthetic limbs. In this paper the authors focus on the design of anatomical robotic hands that use BMI as a critical intervention in restorative neurosurgery and they justify the requirement for lower-level neuromusculoskeletal details (relating to biomechanics, muscles, peripheral nerves, and some aspe...

Although construction has been known as a highly complex application field for autonomous robotic systems, recent advances in this field offer great hope for using robotic capabilities to develop automated construction. Today, space research agencies seek to build infrastructures without human intervention, and construction companies look to robots with the potential to improve construction qua...

Reach and grasp are the two key functions of human prehension. The Central Nervous System controls these two functions in a separate but interdependent way. The choice between different solutions to reach and grasp an object – provided by multiple and redundant degrees of freedom (dof) – depends both on the properties and on the use (affordance) of the object to be manipulated. This same contro...
