[Ilizarov reconstruction of the distal radius after resection of a giant-cell tumor: a case report]. / Reconstruction du radius distal par la méthode d'Ilizarov après résection d'une tumeur a cellules géantes: A propos d'un cas.

We present a case of Ilizarov reconstruction after en bloc resection of the distal radius. An 8-cm resection was required to remove a giant-cell tumor. Reconstruction was based on the ascension technique using an Ilizarov external fixator after corticotomy of the proximal fragment of the radius. Satisfactory reconstruction with formation of a neoarticulation between the radius and the carpus was achieved. Satisfactory wrist function was achieved and the patient was recurrence free at five years. The arguments leading to this therapeutic option are discussed.

[Bilateral total hip prosthesis replacement in a single procedure]. / Bilateralna totalna proteza kuka ugradena u jednom aktu.

This paper is a case report of a patient with bilateral hip dysplasia, bilateral secondary degenerative changes, adduction contracture and serious walking difficulties. The patient has undergone one-stage bilateral hip replacement. This procedure is advantageous because of fast recovery, fewer complications and rehabilitation easier than in the routine operation of two-stage bilateral total hip replacement.

[Arthroplasty in the treatment of congenital anomalies of the hip in adults]. / Artroplastika u lecenju kongenitalnih anomalija kuka u odraslih osoba.

At the Clinic for Orthopedic Surgery and Traumatology in Novi Sad, 79 adult patients with osteoarthritic hip dysplasia underwent total joint replacement surgery in the period 1984-1993. 45 patients were followed-up for an average time of 4.2 years. The results obtained have been evaluated following the criteria of Postel-Merle-d'Aubigne's hip rating system. After surgery 37 (82.2%) patients had minimal or no pain at all, while the hip flexion was over 75 degrees in 35 (75.5%) patients. 9% of patients could not walk longer than 20 minutes with a flexion under 50 degrees. Firm footfall and slight limp in exhaustion occurred in 35 (75.5%) patients, while 7 (15.5%) patients were extremely unstable and were able to get about on crutches. The gathered results confirm that total hip replacement in patients with osteoarthritic dysplastic hip improves stability and hip joint movement as well as pain reduction.

[The value of local administration of antibiotics in treatment of bone infections]. / Vrednost lokalne primene antibiotika u lecenju infekcije kosti.

An open, controlled, randomized clinical investigation was carried out in 33 patients suffering from osteomyelitis. In the first group, 17 patients, a through drainage with sterile physiologic solution was applied, while in the second group, 16 patients, antibiotic was added to the sterile physiologic solution. In all patients values of C reactive protein (CRP) in the blood were examined, and later on every third day after the operation. A significant difference of average values of CRP between the 3rd and 21st day in both groups of patients was established, as well as the similarity in average values of CRP, which points to the fact that the mechanical effect of through drainage is dominant, speaking about rinsing focus of infection and eliminating necrotic tissues and small sequesters.

[Therapy of infected pseudarthroses of the lower leg]. / Lecenje inficiranih pseudoartroza potkolenice.

The retrospective study comprised 23 patients with infected pseudoarthrosis after osteosynthesis of of the lower log fracture treated at the Clinic of Orthopedic Surgery and Traumatology in Novi Sad. Staphylococcus aureus has been the most common causative agent of infection. In all patients debridment of infection foci was performed and reosteosynthesis with the external fixator and in 10 patients spongioplasty was performed in addition. At the control examination good results were achieved in 4, satisfying in 3 and poor in 16 patients. Amputation was performed in 5 patients.

[Osteomyelitis after malleolar fractures]. / Osteomijelitis posle preloma maleolusa.

Over a ten-year period, 485 patients suffering from malleous fracture were operated at the Department for Orthopaedic Surgery and Traumatology in Novi Sad. Postoperative infection appeared in ten cases (2.06%). Eight of these patients primarily had open fractures, and two of them had closed ones. Osteosynthesis of the lateral malleous had most frequently been treated by the use of panel and screws. Staphylococcus aureus was isolated as symptom of the infection in eight cases. In treatment of malleous osteomyelitis, the debridement of focus of infection together with fixation material extraction was the most frequently performed operative method. During a two-year period no exacerbation, seven patients was observed while at control examination three patients had secretion from fistula. Mobility of ankle joint was limited in most cases, while walking imposed no pain.

[Early functional and anatomic results after total condylar knee prosthesis implantation]. / Rani funkcionalni i anatomski rezultati nakon ugradnje totalne kondilarne endoproteze kolena.

The results of total knee replacement in 30 patients have been analyzed. Total knees were implanted during 1990, and the shortest follow-up time after the operations amounted to 6 months. All 30 total condylar prosthesis were of Insall-Burstein posterior stabilized design. The average age of the operated patients was 61 years. Osteoarthritis caused serious knee damage in 21 patients and was the indication for the operation; in 7 patients it was rheumatoid arthritis; in 1 patient synovitis villonodularis; and severe posttraumatic osteoarthrosis in 1 patient. In 18 patients axial knee deformity was noted prior to operation in the sense of valgus or varus. The continuous passive motion machine was used in the postoperative treatment of all patients. Clinically acceptable results were obtained in 90%. Wound healing complications were noted in 2 patients. Full axial deformity correction was achieved in all the patients with a full extension and flexion of over 90 degrees in the operated knees. Preliminary results after the implantation of this type of prosthesis are very encouraging and justify it's further routine use.

[Our results of electrobiologic stimulation of callus]. / Nasi rezultati elektrobioloske stimulacije kalusa.

Results of the achieved electrobiologic calus stimulation in pseudoarthrosis were presented in this paper. A parallel treatment was performed with the apparatus producing low-frequent (EBI) and high-frequent (THELF) pulsing magnetic fields in 11 patients. Results obtained by these methods were compared with those of other authors from literature and they were considered very impressive. From the casuistry presented it was pointed out that the success of these noninvasive methods was confirmed in the most severe cases of pseudoarthrosis where they could be complemented, if necessary.

Intensity of thrombin activity and surgical trauma.

Increased level of in vivo thrombin activity represents the essential mark of prethrombotic state. In order to assess the influence of surgical trauma on the constitution of prethrombotic state immediately after the surgical intervention, dynamic estimations of fibrinopeptide A (FPA) have been done in a group of 18 patients who had undergone abdominal surgery and in the group of 25 patients who underwent the replacement of artificial hip, and who were on preventive treatment with subcutaneous heparin. At the same time the presence of soluble fibrinmonomer complex and, in the group of patients on heparin treatment, the concentration of plasma heparin were examined. The investigations were done before the surgical intervention and on the first, third and seventh postoperative day. Our dynamic study showed the existence of certain relation between the surgical trauma and values of FPA which were the expression of intensity of in vivo thrombin activity. The mean values of FPA increased markedly on the first postoperative day in comparison with the preoperative levels. On the third postoperative day significant reduction of FPA was observed and on the seventh day marked increase was found only in patients who were not on heparin prevention. Although preventive application of subcutaneous heparin did not affect the whole blood coagulability it showed a suppressive impact on the thrombin activity level in examined surgical patients.(ABSTRACT TRUNCATED AT 250 WORDS)
