Congenital absence or traumatic amputation of the thumb is a major disability profoundly disturbing the function of the hand, as the thumb represents an estimated 50% of total hand function. The methods for thumb reconstruction utilizing the index finger were developed some twenty years ago, and progress has been made in the last several years with emphasis on intrinsic muscle reconstruction as...

The human body and the potential to move it affect the way we perceive the world. Here we explored a possible origin of such action-specific effects on perception. Participants were asked to enclose a virtual object by movements of their index finger and thumb and judged either the actual finger-thumb distance or the size of the virtual object subsequently. The visual-haptic discrepancy that co...

OBJECTIVE: To examine the loss of earning capacity and permanent impairment of a cohort of male patients who had experienced finger amputation due to occupational injury. DESIGN: Prospective cohort study. SETTING: University teaching hospital, Hong Kong. PATIENTS: Twenty-eight male patients aged 26 to 55 years who presented with work-related finger amputations in their dominant right hand from ...

Proc (Bayl Univ Med Cent) 2007;20:143–145 I n 1850 Dr. A. Notta, an “internè” in Paris, described four adult patients between the ages of 20 and 60 who had a nodule on a flexor tendon of a finger, thereby inhibiting its normal movement (1). This publication in the Archives Générales de Médecine led to these “nodules” being named “Notta’s nodules,” but a multitude of subsequent papers have large...

To investigate neural coding characteristics in the human primary somatosensory cortices, the cortical representation of two fingers with different levels of functional skill has been focused (the thumb –high dexterous– and the little finger –low dexterous–). The finger dexterity was scored by the Fingertip writing test. In the two hemispheres, dynamic neural synchronization was analysed in the...

The digital nerves to the thumb and index finger have been studied by dissecting twenty-five embalmed upper limbs. The palmar digital nerves to the thumb were constant in position and course, with a short lateral cutaneous branch from the radial palmar digital nerve in 30 per cent of cases. The palmar digital nerves to the index finger had a variable pattern, the commonest arrangement, well des...

Oral habits are very common and one of the most deleterious habits which pose a problem to pediatric dentists. Oral appliances, if inserted for several months, usually eliminate the habit, however, emotional problems, difficulty with speech and hearing, and self inflicted wounds can occur with such appliances. We present a case of 8 year old girl with thumb sucking habit, successfully managed b...

Cutaneous paraneoplastic syndromes are skin and mucous membrane changes that are associated with cancer. We report a previously healthy 76-year-old man who developed marked finger and thumb contracture, pain, and hypersensitivity of both hands who was diagnosed subsequently as having gastric carcinoma with colonic metastasis. After the gastrointestinal tumors were resected the finger and thumb ...
