[Measuring the looseness of the knee joint by using the Kt 1000 arthrometer].

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.

Results of surgical treatment of knee instabilities.

Between January 1, 1981 and January 5, 1987, 146 reconstructive operations for acute (39) and chronic (107) knee instabilities were performed. THe majority of the acute cases were anteromedial (24), and of the chronic instabilities, 33 were anteromedial, 14 anterolateral, and 53 combined anteromedial-anterolateral. In terms of suture, replacement, and reinforcement of the damaged structures of the acute cases, 32 were good, 6 fair, and 1 poor, while the reconstruction, according to Müller, for chronic instabilities produced good results in 34, fair in 59, and poor in 14. It is essential that such operations be performed by a trained surgical team. For success, precise knowledge of anatomy, exact examination, accurate diagnosis, adequate surgical techniques, and careful postoperative treatment are essential.

Surgical treatment of pathologic fractures from metastatic tumors of long bones.

Surgical treatment of 74 cases of impending and established metastatic pathologic fractures were analyzed. On the basis of various reports, the incidence of bone lesions, bone-seeking primary tumors, lesion sites, diagnostic techniques and possibilities, as well as indications for and methods of surgical treatment, are surveyed. Surgical intervention is only one aspect of the different components of general treatment in bone metastases. An aggressive surgical procedure yields very satisfactory results in most cases, compared with those of conservative treatment.

The effect of early anterior approach open reduction with functional postoperative treatment on the early development of the acetabulum in CDH.

Between 1980 and 1983, 30 anterior approach open reductions were performed on congenitally dislocated hips of 29 patients after unsuccessful conservative treatment; patients were between 6 and 18 months old. After the removal of the obstruction from the acetabulum, the reduction was performed with preservation of the limbus. Some part of the capsule was removed to constrict and tighten it and to prevent redislocation. This capsuloplasty demonstrates the success of a Pavlik harness and abduction splint postoperatively, without plaster fixation. The accelerated development of the acetabulum could be observed on radiograph by this functional treatment, compared to the control group treated with the usual hip spica postoperatively. The development of the acetabulum on the operated side almost equals the sound side within a year. If the operation was performed earlier, joint development would be quicker.

[The effect of early surgical reposition of congenital hip dislocation and functional postoperative treatment on the development of the acetabulum].

Authors performed early operative reduction from anterior exposure after unsuccessful conservative treatment on 30 hips of 29 patients in 1981 through 1983. The age of the patients was 6-18 months at the time of the operation. After the excision of the obstacle of the reduction with preservation of the limbus the capsule was closed tight so that it could prevent redislocation. This way it became possible to make functional after treatment without plaster fixation and using Pavlik's harness and abduction splint. It was found that the postoperative development of the acetabulum was accelerated and the development of the acetabular roof reached in average during one year the healthy one and the articular movements were free. The development of the joint was the quicker the younger the age was in which the operation was performed.

[Reoperations in the management of clubfoot].

The results of 118 operations for club-foot are assessed, of these 57 were reoperations. It is stated that the relapse is most often the consequence of the insufficient primary operation and the relapse and the residual deformity are the more serious the more insufficient was the primary operation. The severity of the deformation is defined first of all by the position of the calcaneus. In milder cases the soft tissue operation only may be successful, in the more severe cases bony operation (Evans' operation in this series of the authors) has also to be performed. After their own primary operations reoperation was in 24 per cent necessary. The number of the bony operations was half of the soft tissue operations. The second and rarer case of the relapses was that the foot proved to be even originally rigid, not redressable, "rebel". First of all in these cases may multiple reoperations be necessary and the transposition of the anterior tibial muscle is also useful. The club-foot with a major dominant adduction deformity of the tarsometatarsal joint is thought to be a separate entity and it is corrected with tarsometatarsal capsulotomies or serial metatarsal osteotomies.

[Suture of the meniscus in acute instability of the knee joint].

The authors describe a multiform function of the menisci and the causes of frequently occurring simultaneous injuries of the meniscus and of the ligament. In 26 cases of acute instability of the knee the authors put sutures over the meniscus. In all the cases the results were good, there were no complications and there was no need to make a repeated operation in any of the cases. Making use of the suture over the meniscus, it is possible to improve the results of the surgical treatment of instability of the knee to a greater extent.

[Results in Miacalcic therapy in the analgesic treatment of patients with bone metastases].

Authors have administered between 1984--87 in 30 patients with bone metastasis weekly 3 X 100 iu Miacalcic injections to relieve pain. The literature dealing with the pain relieving effect of calcitonin is summarized and their own results are assessed from more viewpoints. The use of Miacalcic injection is suggested as it was found a modern and very effective palliative medicine for pain relieving.

[Surgical reposition in the management of epiphysiolysis of the femoral head].

In major slipped femoral capital epiphysis the hip function can be restored with a possibly adequate correction of the deformity. Previously authors have performed various inter- and subtrochanteric femoral osteotomies with this aim, in 4 recent cases however the slipped femoral head was reduced operatively according to Dunn and Angel. 2-4 years after the operation good results were found. The blood supply of the epiphysis was not damaged in either case, and the hip motion was restricted in one case only, in which previously 2 other operations were already performed. The operative reduction with the technique described is suggested where the conditions of this considerable operation are given.

[Limb-preserving resection operations in the management of bone tumors of the shoulder region].

Authors describe the frequency of bone tumours in the shoulder region and the anatomical characteristics of this region, that are important, regarding tumour surgery. Six cases are reported in whom resection was performed for malignant, semimalignant and benign bone tumours. In their material one primary and two secondary chondrosarcomas, one Ewing's sarcoma, one osteoclastoma and one benign chondroblastoma were found. Follow-up range was 3-7 years. In two patients partial and total scapulectomy was performed, in the later the proximal end of the humerus was resected only, in three of them endoprosthesis was given, and in one case the missing bone was replaced with a fibular graft. The function of the limbs was in every case, even in those in which the replacement of the bone segment was not carried out, adequate. Metastases developed in three patients, two of them were lost, one is alive. The rest of the patients was free of tumour at the follow-up.

[Clinicopathology of bone metastases causing pathological fractures].

Of malignancies occurring in bones, metastatic tumours are the most frequent. Due to the increase of mean life span and to other factors the incidence of tumours is growing. Nevertheless, survival chances of patients suffering from tumours are also improving due to advance in diagnostics and to the application of complex therapy. These trends have substantially increased the number of recognized and manageable bone metastases. In general, life expectations of a tumour-patient are determined by the metastases therefore, the question of diagnostics and management of bone metastases is worth of special attention. Authors have performed a clinicopathological survey of patients of the past eight years who have suffered fracture due to bone metastases and were treated surgically. In one-third of the patients the primary tumour was unknown at the time of the fracture. On the basis of the histological pattern the detection of the parent-organ, particularly in adenocarcinomas, was not possible. Independently from the radiological appearance of the metastasis simultaneous osteogenesis and osteolysis were histologically observed.

Spondylolysis in osteopetrosis.

We report the occurrence of spondylolysis and/or spondylolisthesis of the lumbar vertebrae in five patients with osteopetrosis, four of them having multiple lesions. The case histories indicate that spondylolysis had developed in the pathological bone as a result of increased stress and that it is an acquired lesion.
