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.

In traumatic amputations in the upper extremities, replantation has been commonly attempted with high success rates. However, successful implies both maintenance of length and good functional outcomes restored hand. Since thumb accounts for 40% to 50% hand function, utmost priority is on salvage thumb. cases when not feasible, various efforts have made replace thumb, including pollicization ind...

The ability to modulate digit forces during grasping relies on the coordination of multiple hand muscles. Because many muscles innervate each digit, the CNS can potentially choose from a large number of muscle coordination patterns to generate a given digit force. Studies of single-digit force production tasks have revealed that the electromyographic (EMG) activity scales uniformly across all m...

Measurement of the pressure applied to the anterior region of the palate and incisor region of the mandible during thumb-sucking was carried out 3 female children. A polyethylene bag embedded with a high-sensitivity small pressure sensor was fixed on the ventral side of the thumb so that the baroreceptor could be interposed between the thumb and palate during thumb-sucking. The children were al...

This paper proposes a design of complete system to identify weak grip strength that is caused by multiple factors like ageing, diseases, or accidents. presents measurement comprises force sensing resistor and flex sensor evaluate the condition hand. The tested gripping pencil cylindrical object using glove, determine Force sensitive (FSR) evaluates applied different parts palm on being grasped....

INTRODUCTION Congenital trigger thumb is an uncommon anomaly of children. Its management is controversial, ranging from observation to extensive surgical release. We report a case of delayed presentation of bilateral trigger thumb along with a brief review of past literature. CASE REPORT A six year old girl presented with fixed flexion deformity of interphalangeal joints of both thumbs and No...

Humans are able to modulate digit forces as a function of position despite changes in digit placement that might occur from trial to trial or when changing grip type for object manipulation. Although this phenomenon is likely to rely on sensing the position of the digits relative to each other and the object, the underlying mechanisms remain unclear. To address this question, we asked subjects ...

Cortical activity allotted to the tactile receptors on fingertips conforms to skilful use of the hand. For instance, in string instrument players, the somatosensory cortical activity in response to touch on the little fingertip is larger than that in control subjects. Such plasticity of the fingertip sensory representation is not limited to extraordinary skills and occurs in monkeys trained to ...
