Lack of caution, insufficient knowledge of anatomy, overrating of one's own abilities and operations which are carried out without restricting blood circulation and without sufficient anaesthesia are the most frequent causes of iatrogenic nerve injuries. On the one hand, the faulty treatment of pre-existing nerve injuries will be discussed; on the other… (More)
For reasons of contents and economy, the construction of medical documentation should be integrated into the secretary's routine work. An efficient and inexpensive microcomputer is able to facilitate and accelerate the typing work of a hand surgical section by the use of a modern data processing system. At the same time important data can be stored for… (More)
This animal study is intended to give information about nerve lesions caused by operation after using different kinds of neurolysis. It can be stated that simple nerve mobilisation leads to iatrogenic damage. The more neurolysis penetrates between the fascicular structure of the nerve, the higher the risk of lesion. After experimental internal neurolysis… (More)
The case of a 54-year-old man is reported who suffered from a painful swollen wrist with signs of inflammation. Due to persisting symptoms and development of osteolysis at the wrist, surgical exploration and excision of a metastatic tumor was performed. It then took further two months to discover the primary tumor, a small-cell bronchogenic carcinoma. This… (More)
Stable internal fixation is an important principle of treatment in hand surgery. Titanium implants have proven themselves suitable and successful. Form and variety of implants satisfy all the demands for internal fixation. A recently developed "osteo-chip-system" will simplify handling.
This paper reports a case of local enlargement of the median nerve in the upper arm due to the very rare condition of hypertrophic neuropathy. A characteristic feature of this affection of peripheral nerves, the cause of which is unknown, is the onion-skin-like hypertrophy of the Schwann cells and chronic neurogenic muscular atrophy. The examination of the… (More)
In the course of two years, 53 traumatic nerve severances of the upper extremity were sutured microsurgically at the Freiburg University Surgical Hospital. Continuity was restored by primary suture in 29 cases, by secondary suture in 4 cases and by transplantation in 20 cases. The first reinnervation potentials showing in the EMG served as evidence of the… (More)
Juxtacortical chondromas represent a special type of chondroma which, when in a parosteal position, have a pedicle on the bone or periosteum. These benign tumours are not specific to any age group or sex. Typical radiological findings are the combination of calcification and adjacent soft tussue vesicles, as well as a rarefaction and sclerosis of the cortex… (More)
Giant cell reactions in the short tubular bones comprise mainly enchondromas, aneurysmal bone cysts and giant cell tumours. In both cases a history of trauma can be related. We therefore agree with Aegerter and Lorenzo that an intra-osseous haematoma due to minor trauma is likely to be of pathogenic significance.
