Authors have proven with previous experiments that the decalcinated bone can be used as transplant. In this paper their experiments to increase the osteogene capacity of this kind of bone for replacement are described. It is stated that with the use of electric after treatment both the speed of the development of new bone after bone replacement both the rebuilding on the recipient bone ends may be advantageously influenced. With their method the bone defect in the rabbit's radius could be healed in four weeks.

The authors survey the possibilities of diagnosis of the frequent injuries of the hand caused by foreign bodies. It is proven by them that almost all foreign bodies can be demonstrated using radiological methods (native picture, ultrasound examination, xeroradiography, CT, MRI). They support the immediate surgical care in the therapy of injuries caused by foreign body, they deal however with the problems of the later therapy, too. Their opinion is backed up by the demonstration of case reports.

The joining of the acromioclavicular dislocation and the fracture of the coracoid process is rather rare. The number of cases described in the world literature is under 20, in this country no such case was described yet. Author reports on a case treated with operation, that healed with good result. The viewpoints of the diagnosis and treatment of this injury are reviewed. The results of the conservative and operative treatment are hitherto equally favourable. Author thinks the operative treatment of injuries with complete dislocation reasonable.

Authors describe their new combined method for treatment of lower leg fractures. To this a new type fixator was developed which makes dynamization also possible. The other novelty in this country is the use of functional external fixing brace. In all of the 38 patients they had succeeded to obtain healing. No complication was found until now.

Authors have performed in 1984-1986 46 Ender nailings based on definite indications as treatment of lower leg fractures in the Department of Traumatology, Arpád Hospital, Ujpest. In their clinical study they stress the criteria of the choice of this method, underline the advantages and disadvantages of the stabilization with elastic nails. This treatment used especially for fractures of the distal third lightens the care, the mobilization, shortens the stay in the hospital, diminishes the number of the septic complications. In many cases authors recommend it as a good alternative method, based on own experiences and results, to surgeons forced to accept a compromise.

The opinions in the question of transitory fixation of the joint during the treatment of the acromioclavicular articulation are rather different. The complications of the widely used methods--break of the implant, its tear from the bone, the wandering and the disturbances of wound healing--are well known. To decrease the number of complications authors have developed a new type of hooked plate. The plate is fitted to the anterior surface of the acromial end of the clavicle and its hook is fixed from below in the bore hole of the acromion. To choose the optimal place of the bore hole a drill guide was prepared. The operative method is described and the advantages of the method are summarized. The "Debrecen-plate" was used during 2 years in 39 injuries. 35 patients were controlled 6-24 months after the operation. Based on the results of the treatment a wider use of the method is suggested.

Authors elaborated a modular tumor prosthesis by the use of which the bone segment lost after the resection of hip, femur, knee and proximal tibial tumors can be supplemented in the desired measure. The components of the prosthesis set and the field of its use are described. In the last one and half year modular tumor prostheses were inserted in 10 patients: in 6 primary bone tumors and 4 solitary metastases. One shoulder, 5 hip, 3 stiff knee and 1 tibia diaphysis supplementing modular prostheses were inserted. In spite of 2 complications the initial experiences are encouraging, and in adequate indication the possibility of retaining limb and articular function beside good functional results is given.

Authors measured the stability in the sagittal plane of the intact knee joints of 50 young men with the MEDmetric KT 1000 apparatus. The greatest movement during the measurements on 100 knees was observed in 25 degrees flexion and during the application of force 89N. In 70 degrees flexion the movement was only half of that observed in 25 degrees flexion. The difference of the average movements measured bilaterally was neither in active nor in passive experiments more than 0.5 mm. The difference between the average values of the compliance indexes on the left and right side was only 0.01 mm. In all measurements the frequency distribution of the differences between the two sides was essentially the same. The difference between the movements on the two sides did not exceed 2 mm-s in 90-100 percent of the cases.
