[Chronic paronychia and synovialitis of extensor tendons due to Mycobacterium marinum. Is diagnosis or treatment the problem?].

Most infections of the upper extremity are caused by staphylococcus or streptococcus and respond well to beta-lactam antibiotics. Hand surgeons should be aware of the possible diagnosis of Mycobacterium marinum infection: 90% of the lesions are found in the upper extremity. We present a case of a chronic, cutaneous lesion of the right middle finger with synovialitis of the extensor tendons observed in a 35-year-old woman.

[Misinterpretation of a solitary breast carcinoma metastasis of the hand as an enchondroma. Case report and literature review].

Carcinoma of the breast is the third most common primary tumor leading to metastases in the hand. It is preceded by carcinoma of the lung and kidney. A review of literature is presented, following the case report of an isolated skeletal metastasis in the middle phalanx of the left ring finger in a 67-year-old patient seven years after mastectomy of the right breast.

[Paralysis of the interosseous nerve by a tendinous margin of the extensor carpi radialis brevis].

A 41-year-old woman was seen with a posterior interosseus nerve palsy. Exploration showed this to be caused by entrapment and neurotmesis of the posterior interosseus nerve under the tendinous margin of the extensor carpi radialis brevis muscle. One year after nerve reconstruction, the functional outcome was nearly normal.

[An unusual case of metastasis to the soft tissues of the palm of the hand with compression of the median and ulnar nerve by kidney cancer. Case report].

The incidence of secondary tumors in the hand is set slightly over 0.1%, the primary tumor localized in the lung, followed by the breast and the kidney. The authors describe a case of a renal carcinoma metastatic to the soft tissue of the palm of the hand in a patient who had undergone nephrectomy for carcinoma of the right kidney eleven years previously.

[Unusual course of scapho-capitate syndrome].

The scapho-capitate-syndrome has been defined as combined fractures of the scaphoid and capitate with rotation of the proximal fragment of the capitate through 90 or 180 degrees. Most injuries are due to falls from heights or car accidents. Only 26 cases of the scapho-capitate fracture syndrome have been reported since 1937.

[Melorheostosis of the hand (report of 2 cases)].

Melorheostosis is a rare monostotic or polyostotic bone disease of unknown etiology. It is characterized by a slowly progressing linear hyperostosis, fibrosis of the skin and subcutaneous tissues, contractures of joints and aching pain. The lower extremities are involved much more often than the upper extremities.

[Ipsilateral inverse fibula transposition for treatment of congenital tibial pseudarthrosis].

Congenital pseudarthrosis of the tibia is one of the most challenging problems in reconstructive surgery. A wide variety of surgical methods has been utilised to treat this condition: One is the free transposition of the vascularised fibular segment to bridge the gap of pseudarthrosis. The authors report their experience in using a vascularised pedicled fibular segment of the ipsilateral fibula with reverse peroneal flow.

[A realistic practice model for learning microneural surgery without experiments on live animals].

The increasing importance of microneurosurgery in hand and plastic surgery makes it necessary for surgeons to familiarize themselves with these techniques. In most training programs, anesthetized rats have been used to learn basic microneurosurgical techniques. Ethical considerations, the costs involved, and the legislation concerning experiments with live animals permit extensive training in microneurosurgery in only a few medical centers.

[Isolated compression of the dorsal branch of the ulnar nerve].

The dorsal branch of the ulnar nerve was dissected in 20 upper extremities. The nerve arises from the ulnar aspect of the ulnar nerve at an average distance of 8.5 centimeters from the proximal border of the pisiforme.
