“…In their first report [3], probably following Spiegel and Wycis [2], the first (more anterior) pallidotomy was made by multiple electrolytic lesions at different sites with a direct current (10 mA, 1 min each, the electrode being used as the anode). This method was chosen to minimize heating and to avoid thrombosis; however, it was difficult to control lesion generation.…”

“…String electrodes were also used in other centers [37,60], but eventually rod (straight needle) electrodes became more popular and have since prevailed. In fact, Roeder and Orthner [3] started using string electrodes developed by Riechert and colleagues in Freiburg [15,16,17]. They switched to modified electrodes manufactured in the Zentralwerkstatt of the Max Planck Institute, Göttingen, with a gauged driving mechanism and some other improvements [14].…”

“…In their monograph from 1962, they mentioned groups from different countries who had also adopted stereoencephalotomy, and Fritz Roeder and Hans Orthner, two professors of neurology from Göttingen, range among the most frequently cited authors [2]. They were the first to alleviate hemiballism by pallidotomy without compromising voluntary movements [3]. Furthermore, they successfully performed some of the most demanding stereotactic procedures, such as bilateral pallidotomy [4,5] and the first medial mesencephalotomy [6], and, ultimately, they introduced ventromedial hypothalamotomy [7,8].…”

During the 1950s through the 1970s, Hans Orthner and Fritz Roeder, two German neurologists from Göttingen, developed a sophisticated technique to perform functional stereotactic surgery with outstanding accuracy. They introduced direct air ventriculography performed in the same surgical session as the ablative stereotactic procedure. For individualized surgical targeting, Orthner prepared a stereotactic atlas (>60 brains) with an ingenious brain-slicing device, the Göttinger macrotome. Brains were grouped based on similarity of six different head and ventricle measurements. A brain cluster representing the best match for a patient was selected for stereotactic targeting. Stereotactic lesions were tailored in an individual manner and shaped by stringing together multiple small coagulations following intraoperative test stimulation. This was achieved from a single probe trajectory by using well-engineered string electrodes with calibrated curving and involved laborious calculations. Only high-frequency thermocoagulation was regarded as appropriate for lesioning. With this meticulous technique, the most advanced stereotactic procedures were performed, including bilateral pallidotomy that ultimately could be restricted to the ansa lenticularis and ventromedial hypothalamotomy, the most delicate stereotactic operation performed to date. Outside Göttingen, this technique has only been used by Prof. Dieter Müller in Hamburg, Germany. This elaborate stereotactic approach is widely unknown and deserves to be discussed in a historical context.

After chemothalamectomy for advanced parkinsonism, one of our patients developed dyskinetic symptoms which suggested the diagnosis of hemiballism. These symptoms persisted after a second lesion had been placed slightly deeper than the first. The patient died 5 months after the operation from causes which had no evident connection with the neurological disease. It seemed that the history of this case, together with the report of the autopsy findings, might give useful information on the morbid anatomy of hemiballism.A 35-year-old white man was admitted in June, 1957, with a past history of operation for cleft palate and of bronchiectasis.The actual illness started in 1946 with slight tremor of the left thumb and involved the whole extremity soon afterwards. The other arm became gradually affected by tremor and rigidity 6 months later. Four years later an attack of "severe flu"increased the severity of the Parkinson syndrome. Rigidity increased and became generalized; the arms attained a rigid flexed posture. In 1955, flexion deformities in the hands and progressive speech disturbances appeared, and the clinical pic¬ ture showed a steady progress of the disease. ExaminationClinical Findings.-The patient was a well-de¬ veloped and well-nourished man of erect posture. His neck was flexed and the head tilted slightly to the right, with some tremor. The face was markedly mask-like, with a staring expression. He had a slightly shuffling gait with no associated movements of the arms, and slight tendency for retropulsion could be observed. The speech was stuttering, the voice low, and micrographism was exhibited.Cranial Nerves.-The examination was negative, except for blepharospasm and lack of convergence of eyes.Upper Limbs.-Marked tremor was present bi¬ laterally. Bradykinesia, more pronounced on the left side, was noted. Both hands exhibited dystonic deformities which were not completely fixed. Both
