[Plastic Operations of the Anterior Cruciate Ligament (Part II).].

M Weissinger, A Keppel, C Helmreich

Acta Chir Orthop Traumatol Cech. 1995; 62(2):69-75

Between January 1, 1988 and December 31, 1993 125 operations of the anterior cruciate ligament were performed in 27 women and 98 men. 58 operations were on the left side, 67 on the right side. In the case - history an injury during leisure time was recorded in 84.8% of the patients, during sports activities in 94%. Of 125 patients 122 were examined by arthroscopy, three were operated by the semiopen approach. The mean age at the time of surgery was 29 years. The selection of the time of surgery indicates that 98% of the patients were operated as early secondary operations and as secondary operations (after 4 weeks). Of 125 patients 122 (97.6%) were...

[The role of collagen implants containing the tripeptide gly-his-lys in bone healing process.].

M Adam, O Cech, H Pohunková, J Stehlík, Z Klézl

Acta Chir Orthop Traumatol Cech. 1995; 62(2):76-85

The authors prepared 12,5% collagen gel, that they supplemented by tripeptide gly-his-lys. peflacin and hypersulfated glycosaminoglycan (HSGAG). By means of I125 marking they followed up its absorption from small polyurethan sponges placed under the skin of rats. They found out, that absorption of gel without HSGAG is faster. No collagen antibodies (type I., II., III.) against the gel were formed neither in the experiment with rabbits, nor later on with minipigs when gel was placed into bone defects. Further on presence of microorganisms in the gel was looked for with negative results on various bacteriological nutrient media. The gel was used in a...

[Plate fixation in fractures of the proximal half of the shaft of the radius.].

J Bartonícek, J Stehlík, D Jehlicka

Acta Chir Orthop Traumatol Cech. 1995; 62(2):86-93

The authors describe their own experience with plate stabilization of the fractures of the shaft of the radius in group of 13 patients. The plate-stabilization was performed from the Henry approach by means of semitubular plate. Bone-union without infection or palsy of r. profundus n. radialis was achieved in all cases. Based on their own experience the authors recommend the Henry approach and stabilization of the plate with minimum 3 screw in the proximal and distal fragments. In comminuted fractures the primary iliac bone grafting is necessary. Key words: fractures of the proximal shaft of the radius, Henry approach, plate-stabilization.

[Experience with hybrid hip prosthesis walter-motorlet/poldi.].

P Vavron, V Stedrý

Acta Chir Orthop Traumatol Cech. 1995; 62(2):94-98

In 1987-1992 at the Orthopaedic Clinic IPVZ 108 hybrid endoprostheses of the hip joint, type Walter-Motorlet/Poldi were implanted (non-cemented socket Walter-Motorlet, cemented shank Poldi). The authors submit evaluations of 75 endoprotheses made 2-7 years after surgery (mean follow-up period 3 and a half years). The mean age of the patients was 49 years (range 39-62 years), the most frequent preoperative diagnosis was secondary postdysplastic coxarthrosis (52%), other diagnoses were primary coxarthrosis (24%), idiopathic necrosis of the head of the femur (20%) and posttraumatic coxarthrosis (4%). Genneral evaluation according to Harris revealed excellent...

[Cementless Endoprosthesis of the Hip Joint ABG: Description of the Implant, Operation Technique.].

V Stedrý, Z Matejovský

Acta Chir Orthop Traumatol Cech. 1995; 62(2):106-110

A non-cemented endoprosthesis of the hip joint ABG is producet by Howmedica Co. from a titanium alloy. The socket is hemispherical, primarily anchored according to the press fit principle. The external surface of the annulus is covered by a layer of hydroxyapatite. The shape of the shank is anatomical, it respects the anterior curvature of the femur and the anteversion of the neck of the femur. Its primary stability is ensured by the shape of the shank, the secondary stability is achieved in the process of osteoinduction in the metaphyseal part covered by hydroxyapatite. Between 1992 and 1994 18 hip joints were operated. No peroperative nor postoperative...

[Results of surgical synovectomy of the knee joint in patients with rheumatoid arthritis.].

C Kopác, F Makai, J Machácová

Acta Chir Orthop Traumatol Cech. 1995; 62(2):111-113

The authors evaluate the results of synovectomy of the knee in 216 patients (83 men and 133 women) with rheumatic arthritis (RA); 35 patients with juvenile chronic arthritis (JCA) in the evaluated group account for 16,2%. On average 2.3 years have elapsed since the operation. They evaluate the peroperative macroscopic appearance of the synovial membrane, the damage of intraarticular structures, the effect of surgery on the range of movements. Comprehensive evaluation according to Aidem -Baker revealed very good results in 52.8%, good results in 36.1%, satisfactory results in 7.4% and poor results in 3.7%. Key words: surgical synovectomy, synovectomy...

[Dislocation of an endoprosthesis of the hip joint operated by the open method.].

J Musialek, K Foldyna, J Kundrát

Acta Chir Orthop Traumatol Cech. 1995; 62(2):114-116

The authors evaluated in a series of endoprostheses of the hip joint the X-ray documentation and peroperative revision findings in 8 patients who from a total of 16 dislocations (2.2%) were subjected to surgical revision. Conditions of a postdysplastic hip joint with previous surgery predominated (62%). In half the reoperated hip joints the cause of dislocation was a malposition of one of the components. The most frequent surgical revision was replacement by a femoral component with a longer neck (88%). Key words: endoprosthesis of the hip joint, dislocation, treatment of dislocation.

[Legg-calvé-perthes disease - contemporary diagnostic possibilities.].

V Dzupa, M Bartos

Acta Chir Orthop Traumatol Cech. 1995; 62(2):117-127

The authors give a review of imaging techniques used at present in the diagnosis and follow-up of changes in Legg-Calvé-Perthes disease. Based on data in the literature and their own experince, the authors draw attention to the advantages and disadvantages of different diagnostic methods. They discuss possibilities of different imaging techniques in the early diagnosis of the disease. In their opinion a high-standard X-ray examination is still the basic examination. A suitable supplement in particular in a early stages are sonographic, scintigraphic and magnetic resonance examinations. Key words: diagnosis of Legg-Calvé-Perthes disease, X-ray examination,...
