[Non-cemented Prosthesis of the Walter-Motorlet Hip Joint Description of Implant, Indication and Surgical Technique.].

I Landor, A Sosna

Acta Chir Orthop Traumatol Cech. 1992; 59(3):132-138

The authors discuss indications and application of non-cemented prostheses of the hip joint, type Walter-Motorlet. In the first part they give a detailed description of the implant and its range of sizes. Next they deal with possible indications and contraindications of non-cemented prostheses of this type. The above implant is used above all in biologically young patients. It has substantial advantages in dysplastic acetabula and in protrusions. Favourable results are obtained also in rheumatoid arthritis. Metabolic bone diseases which do not make it possible to create a satisfactory secondary fixation are a basic contraindication. The authors discuss...

[Prosthesis of ligament by specially treated collagenous tissue.].

T Trc, H Pohunková, M Stol, J Novotná, M Adam

Acta Chir Orthop Traumatol Cech. 1992; 59(3):139-142

Artificial prostheses of ligaments are associated with many problems. At first they take over the function of the ligament, later however their strength declines. Therefore at present collagen autotransplants are prefered. Prosthesis made from processed seem however promising, after their breakdown they should be replaced by the patient's connective tissue with an orientation of fibres resembling the original ligament. The poor results reported in the literature are probably due to inadequate treatment of these ligaments. The authors mention their own method of treatment of collagen and its use as a prosthesis of ligaments in experiments on dogs. These...

[Bone Reconstruction of Autolyzed Antigen-free Allogenic /AAA/ Bone in Children and Adolescents with Benign Bone Tumours.].

M Janovec, B Crha, I Okác, M Sommernitz, M Straka, J Bajerová

Acta Chir Orthop Traumatol Cech. 1992; 59(3):143-150

The authors describe in detail the preparation of six batches of human AAA/autolyzed antigen-free allogenic bone/ prepared in 1985 to 1988. This bone was administered to a total of 48 children and adolescents aged 6 to 19 years. It was used to fill cavities after metaphyseal connective tissue bone defects /31 x/, solitary bone cysts /10 x/, enchondromas /5 x/ and fibrous dysplasia /2 x/. The observation period was 2 years and 2 months to 5 years and 9 months. The mean volume of the cavities was 21 ml. In all patients the X-ray pictures were evaluated in a chronological sequence and changes on the host s bones in the cavity and the inserted AAA bones...

[Experience with Implantation of TP of the Coxa in Osteoporosis.].

J Vojtassák, F Makai, P Maresch, J Opatík, M Kokavec

Acta Chir Orthop Traumatol Cech. 1992; 59(3):151-153

Based on X-ray pictures, the authors evaluate the state of osteoporosis by means of bone indexes after implantation of a total prosthesis of the hip joint. They correlate the state of osteoporosis found in the patients with the clinical condition. After 5 years following implantation of TP they found a minimal progression of osteoporosis without restriction of the function of TP of the coxa. Up to ten years after implantation the progression of osteoporosis is apparent, while the functional state of the TP is adequate. After 10 years there is further progression of osteoporosis with restricted function of the TP of the coxa. The cause of progression...

[Peritenonectomy in the treatment of achillodynias.].

K Urban, P Svoboda

Acta Chir Orthop Traumatol Cech. 1992; 59(3):154-157

The authors investigated a group of 29 patients, incl. 21 sportsmen with achillodynias. Athletes and football players predominated. Peritenonectomy was indicated when conservative treatment was exhausted and did not achieve marked improvement. The above mentioned operation was, depending on pathological changes of the tendon and its surrounding structures, supplemented by other provisions. After operation the plaster splint was applied only before the surgical wound healed. The follow-up period was 9 months to 5 years. Marked improvement and improvement was recorded in 27 patients, i.e. 94 %. Evaluation was influenced by the presence of other pathological...

[Our experience with bone scintigraphy in the diagnosis of wrist injuries.].

J Fousek, R Procházka, O Belohlávek

Acta Chir Orthop Traumatol Cech. 1992; 59(3):158-163

The authors evaluate, based on a group of 40 patients, the contribution of bone scintigraphy to the diagnosis of injuries of the wrist; scintigraphy has a high sensitivity and specificity in fractures of the navicular bone. In addition to injury of that bone the scintigraphic picture of both wrists makes it possible to focus attention also on affections of others structures and thus to contribute to a better diagnosis and treatment of the wrist. The authors found in fractures of the navicular bone in 70 % agreement with the X-ray examination made several weeks after the injury. As regards injuries of other bones of the wrist positive on scintigraphy,...

[Resection of the Distal Ulna by Darrach's Method.].

M Kitka, V Blasko

Acta Chir Orthop Traumatol Cech. 1992; 59(3):164-166

The authors submit data on a group of 7 patients who were subjected to resection of the distal portion of the ulna according to Darrach's method. The operation was indicated in all patients on account of pain, restricted mobility of the wrist and deformity. The authors confirm that resection of the distal ulna by Darrach's method, when correctly indicated, provides very good results when the patients have systematic rehabilitation after treatment. Key words: resection of ulna, Darrach's operation.

[Results of treatment of acute injuries of the thoracolumbar spine by ridged plates.].

O Vlach, O Václavek

Acta Chir Orthop Traumatol Cech. 1992; 59(3):167-172

The authors evaluate the results of surgery of fresh injuries of the thoracolumbar spine achieved by transpedicular fixation, using ridged plates. At the orthopaedic clinic in Brno-Bohunice this technique was systematically introduced in 1989; in 1991 they started to use a better principle of stabilization by an internal fixation device. The authors used plates fixed in a transpedicular way in 58 injured subjects. Most frequently fractures of L1, T12 and L2 were involved, usually of a burst type. In more than half the patients they recorded a nervous deficit of varying degree. They stabilized usually typically four mobile segments and fused two internal...

[Three-dimensional Visualization during CT Examination in Coxa Vara of Adolescents.].

M Dostál, P Zmrzlík, M Pach

Acta Chir Orthop Traumatol Cech. 1992; 59(3):173-178

The authors demonstrate two patients with adolescent epiphyseolysis of the head of the femur which is visualized by means of special software of so-called three-dimensional reconstruction of CT pictures. The preoperative visualization made it possible in the first case to define more accurately the surgical scheme of Southwick's two-plane osteotomy of the femur, in the second case the indication for Dunn's subcapital osteotomy of the neck of the femur. The subsequent postoperative visualization gives a spatial idea of the results of the two types of operations. In the discussion the authors deal with the range of indications for the use of the above...

[Early Diagnosis and Follow-up of Perthes' Disease by Magnetic Resonance.].

V Dzupa, J Prádný, M Bartos

Acta Chir Orthop Traumatol Cech. 1992; 59(3):179-181

The authors present a case-history pertaining to the early diagnosis of Perthes' disease by magnetic resonance in a patient with a marked clinical symptomatology and a negative classical skiagram. Typical changes on the X-ray picture developed after a three-month interval. Confirmation of the importance of magnetic resonance for early diagnosis of Perthes' disease is consistent with the quoted literature. Key words: early diagnosis, Perthes' disease, magnetic resonance.

[Covering of an extensive defect of the leg by a free cross flap from the m. Latissimus dorsi.].

M Tvrdek, J Kletenský, Z Pros, J Stehlík

Acta Chir Orthop Traumatol Cech. 1992; 59(3):182-185

The authors demonstrate on a clinical case the procedure used to cover an extensive defect of the leg which with regard to the vascularization of the leg and extent of the defect could not be resolved by commonly used procedures. The needed tissue was obtained from a flap from the m. latissimus dorsi transferred to the site of the defect as a free cross flap. Key words: microsurgery, reconstructive.
