[Treatment of intertrochanteric fractures by Pohl's screw (author's transl)].

The dynamic slide osteosynthesis of Pohl - a single acting method - is compared to other methods of operations. 103 patients with intertrochanteric fractures of the femur were treated by "Pohlsche Laschenschraube". The average age of patients was 76.7 years. The average stay in our hospital lasted 43 days. 16.5% of the patients died. 27 patients were examined two years after operation. The further study is based on clinical documents.

[Clean field-technique to reduce the local air contamination level in operating rooms. Clinical experiences in accident surgery (author's transl)].

A newly developed technique to reduce the local air contamination level in operating rooms is described. After physical and hygienic evaluations a mobile clean field-equipment has been used at 97 traumatic operations. At 66 operations about 300 aerobiological samples of the contaminated room air and simultaneously of clean field-air at the wound site were collected. It is shown that the bacterial level of clean field-air is comparable with those levels in a sterile operating enclosure. The advantages of the new technique and first experiences under practical operating conditions are discussed.

[Effect of direct current on the healing of cancellous bone defects in animal experiments: quantitative results (author's transl)].

The examinations were made in grown up rabbits of different races in a right to left attempt. A defect like a slot was placed transcondyloid and sagittal by an osteotomy in the condyle of the femur. The fixation of the condyle was performed by a screw poled as kathode. The anode was planted in the extensor muscles of the femur. Direct current from a battery on the neck of the rabbit was running subcutan by stranded wires. The stimulation was performed by direct current of 10 and 17,5 microamperes for two, three and four weeks. The quantitative survey of 44 pairs of bone showed a significant acceleration of bonegrowth by direct current indicated by a higher weight of the new grown bone in the osteotomy slot. The bones, stimulated by 10 and 17,5 microamperes showed no significant differences among themselves. Possible reasons leading to bonegrowth are discussed.

[Influence upon the longitudinal growth of extremities by direct current in animal experiments (author's transl)].

Direct current under certain conditions will be show a positive effect on the longitudinal growth of long bones during growing-age. Examinations were made in 8 to 10 week old rabbits in a right to left attempt. The electrodes were implanted in the midshaft of tibia. The stimulation was performed by direct current of 20 and 30 microamperes. The quantitative evaluation of 12 oxytetracyclinelabled pairs of bone showed a statistically significant increase of longitudinal growth on the electrically treated side as compared with control. Possible reasons leading to bone growth by electrical stimulation are discussed.

[Complications after total hip endoprosthesis: fracture of the femur and simultaneous fracture of the cement mount of the acetabulum (author's transl)].

Report about a rare complication after total hip endoprosthesis with a simultaneous rupture of the cement mount in the acetabulum (due to a trauma) and a fracture of the femur. The x-rays and the intraoperative findings were interpreted erroneously; therefore the diagnosis was delayed. A second operation was needed to reimplant the acetabulum. During the same operation a wrong position of the prosthesis (outward rotation) had to be corrected.

[Surgical treatment of chondromalacia patellae according to Maquet/Bandi--indication, technique, results (author's transl)].

Degenerative changes of the femoropatellar joint are being observed increasingly more often. These may be due to various disturbances of the gliding movement and gliding plane. The article describes the clinical and x-ray symptoms and the therapy; in most cases, additional surgery will be necessary besides antepositioning according to the technique described by Bandi.--Follow-up examinations of 32 patients showed that in 28 of 35 surgically treated knee joints, a positive influence had been exercised on the complaints, load capacity and walking distance.

[Arthrodesis of the wrist with the use of bone graft and stable plate osteosynthesis. Results in 27 patients (author's transl)].

36 arthrodesis of the wrist have been controlled. The operative technique could be divided into two groups. On the first group a stable osteosynthesis and cortico-cancellous bone graft have been used. The second group has been treated by other internal rigid fixation. 13 patients of the first and 14 of the second group have been followed up. It was possible to obtain an arthrodesis by all methods. The stable kind of arthrodesis makes the handposition secure, the postoperative immobilization in cast much shorter and avoids the danger of pseudarthrosis.

[Causes and treatment of delayed callusformation and pseudarthrosis following fractures of the shaft of the humerus (author's transl)].

In the OHH, during the years 1969 to 1974, 28 patients were operatively treated because of delayed callusformation or pseud-arthrosis, following a fracture of the shaft of the humerus. It was possible to inquire about and to re-examine 20 patients. The operative treatment had, when possible been achieved by osteosynthesis through plates (25 cases). Each of the so treated cases lead to healing of the bone, additional nerve lesion did not in one case occur because of the operation. Objectively seen, there existed in 7 patients a slight, final restriction of movements, for the abduction and outside rotation in the shoulder joint. 6 patients complained of being sensitive to weather changes. The different treatment method of the fracture of the humerus and pseudarthrosis was discussed.

[High tibial osteotomy--fixation by means of external fixation--indication, technique, complications (author's transl)].

High tibial osteotomy has proved its value in the treatment of gonarthrosis with or without axis deformity. The thrust of weight-bearing and other stresses is lessened on the degenerated tibial condyle and transferred to the more normal condyle. The stable fixation by means of external fixation allows early movement of the knee joint.-R-ferences to operative technique, indication, complications and after-treatment.

[Stimulation of longitudinal growth of long bones through electrical current. Scintigraphic examinations on ribbit tibiae].

Report on szintigraphical examinations using 87-mSr in young rabbits treated by direct current of different intensity varying from 2.5 to 40 micro-Ampère. The current was applicated to one tibia using the other as comparison. Corresponding to the realised growth-increase by electric stimulation there was found an increased uptake of 87m-Sr in the electro-stimulated tibia in all 16 rabbits.
