Primary amputation of the lower extremity has become rare in the last years due to the advances in rigid fixation of the bone, plastic and microsurgical techniques and aseptic surgery. Primary amputation is indicated in the presence of non-reconstructable lesions of vessels and/or nerves, secondary amputations when vascular, neural or septic complications occur.

Using somatosensory evoked potentials during the operation it is possible to get the following information concerning brachial plexus function: Function of the roots. Which parts of the brachial plexus are completely destroyed and which are in regeneration? From which level is it possible to repair an injured nerve with a nerve graft? In cases of severe upper arm injuries: Is there function in the brachial plexus and is it appropriate to do a replantation?
In eighteen cases of condylar, subcapital and other intraarticular fractures of phalanges, especially in cases of fractures in childhood cerclage and suture with Dexon were used. This osteosynthesis was sufficiently stable to permit exercise.
The number and the location of the venous anastomosis in finger replantation are discussed. The principle: 'two veins for one artery' has been given up in favour to do only one venous anastomosis. A vein on the palmar side should be preferred. Here the anastomosis is protected by a thicker layer of subcutanous tissue. In addition this technique allows to do the total vascular reconstruction without turning the hand. In a number of 84 finger replantations there was a failure rate of 9,5% by using only one vein for replantation. In 17 finger replantations using one volar vein we lost only one finger (5.9%).
The animal experiments demonstrate the possibility of differentiating intraoperatively between motor and sensory fascicles of the peripheral nerve. This differentiation is based on somatosensory evoked potentials, which are summarized with an averager. Peripheral nerves in four patients have been reconstructed with this method. The first (median nerve lesion) has complete motor function of the thenar eminence seven months after operation.
If one finds three digital nerves on the flexor side of the finger, most often it will be due to a proximal ramification of the radial digital nerve, which gives a dorsal branch to the extensor side of the finger. In one case, however, we have seen three true digital nerves on the flexor side of the index finger.
Anatomical, physiological, physical and technical reasons support a transverse ureteral incision for stone removal. Its advantages are confirmed by early clinical and radiological results.
We present a thirty years old man with a large scrotal cavernous hemangioma and discuss the diagnosis and the therapeutic problems.

Adrenal cysts are rare, mostly harmless, processes, either congenital inborn or acquired by regression, bleeding, infection and tumor. In the case of endocrine dysfunction with arterial hypertension and local expansion with perforation into the retroperitoneal, peritoneal and pleural cavity, purulence, bleeding and vasal obstruction complications are serious. In the differential diagnosis carcinoma of the kidney and the adrenal gland should be excluded.
