[Electronic medical history: utopia or reality?].

With the advent of computers in medicine, the patient's chart has a more varied function. The basic use has been as the physician's instrument to provide information about diseases and their evolution. In order to link the physician with the capacity of a computer, a common language was elaborated based on the patient's chart. Computerized charting now makes possible not only improved communication and administration but also serves as a statistical databank. Important applications of a medical databank are statistical analysis of the chart, quality control of medical practice and facilitation of scientific studies. The patient's chart becomes a powerful multifunctional instrument in the clinic, the practice, and in research.

The late reconstruction of the ligament of the metacarpo-phalangeal joint of the thumb.

The disruption of the ligaments at the level of the MP-joint jeopardizes the function by lack of stability. The reconstruction by free tendon grafting, anchored in a dorso-lateral plane in the metacarpal an in the proximal phalanx, restores stability and good functional results in spite of a slight amount of loss of flexion. Two out of 25 operated thumbs failed and fusion of the MP-joint was necessary. A minimal limitation of flexion may be desirable since a tendon graft never restores a full physiological function. Our data show no need for K-wire transfixation of the MP-joint, since there is no evidence of a difference in late stability with or without such additional fixation. The mean pinch-grip pressure, restored to normal in the majority of cases, was not influenced by the mentioned reduction of flexion nor by the amount of stability restored.

[Anatomic basis of a new concept of stability of the carpus].

Based on anatomical and biomechanical evidence, we conclude that the stability of the carpus relies on the lunate bone which is the centre of the longitudinal as well as the transverse functional axis. The lunate is firmly stabilised proximally to the radius and the radio-ulnar ligament complex by the proximal V-ligament, and so becomes a weight bearing structure. It is anchored by strong ligaments to the scaphoid on one side and the triquetrum on the other, thus forming a 3-bone intercalary system, which is in turn guided by the palmar distal V-ligament and the dorsal radio-triquetral ligament.

[Tumor of the hand, free flap and irradiation. Anatomo-pathologic study apropos of 1 case].

After excision of a recurrent squamous cell carcinoma of the ulnar border of the right hand and forearm, we covered the defect with a free scapular flap. The flap and the tumor site were irradiated post-operatively (4 000 Rad). In spite of the irradiation the tumor recurred and we performed a below elbow amputation. Angiography of the amputated part showed the patency of all the flap vessels. However the histological features confirming the effect of the radiotherapy, particularly on the vessels, showed intimal proliferation and signs of necrosis of the media. We concluded that despite these findings the viability of free flaps is not jeopardized by radiotherapy, as long as their size is not reduced by more than 30% as compared to normal, and as long as the vascular anastomoses are done outside of the field of irradiation.

Epithelioid sarcoma.

Epithelioid sarcoma is a malignant soft tissue tumor characterized by its propensity to occur in the distal extremities as a nodular lesion and its slow and asymptomatic growth. Microscopically, the diagnosis is difficult. Therefore the interval between onset of symptoms and diagnosis averages one to three years. 10 years survival after onset are not uncommon whatever the treatment chosen. Having to treat such a tumor of a hand, 8 years after onset, we decided a local radical excision by micro-surgery instead of amputation or mutilating excision. Long standing clinical follow-up will add valuable information as to the cure of the upper extremity.

[Osteoid osteoma of the hand. Case representation with special reference to magnetic resonance tomography and litrature review].

The pre-operative diagnosis of osteoid osteoma of the first metacarpal bone was suggested by Magnetic Resonance Imaging in a 15 year old girl. As indicated in the literature, osteoid osteoma of the hand is relatively rare. The symptoms and the x-rays features of osteoid osteoma are essentially independent from the location consisting in rather unspecific pain and radiographically osteolytic nidus surrounded with sclerosis. In the few published cases with MR Imaging, the nidus shows high signal intensity surrounded by low signal intensity in the area corresponding to the radiographically visible sclerosis.
