[Longterm results of poldi hip replacement.].

R Hart, Z Rozkydal

Acta Chir Orthop Traumatol Cech. 1999; 66(3):139-145

The authors evaluated 124 patients operated on by means of cemented Poldi THR in the period 1980-1986 on average 14,2 years after the primary implantation (12,2-18,0). Average age of patients was 55 years (in the range of 33 to 75). Pre-operative diagnosis was osteoarthritis in 78 cases and rheumatoid arthritis in 46 patients. All patients had normal anatomical relations. The implants applied included a 49 mm polyethylene cup and a bananashaped CoCr polished stem with 32 mm head with the use of 1st generation method of cementing. Harris Hip Score averaged prior to the surgery 49 (19-52) and after the surgery 68 (49-98). In 59 patients Harris Hip Score...

[Internal Fixation of Sacro-iliac Joint in Unstable Fractures of the Pelvic Ring.].

B Soukup

Acta Chir Orthop Traumatol Cech. 1999; 66(3):146-151

Unstable fractures of the pelvic ring are always serious injuries posing problems from many aspects. Among the most serious are definitely unstable fractures of the pelvic ring with both vertical and rotational instability, i. e. type C fractures according to AO classification scheme. The recent therapeutic concept recommends in case of these fractures an active reconstruction on the dorsal SI complex which evidently improves the final perspective of patients with such a severe injury. The author presents his own clinical experience and literary data relating to the treatment of 11 patients who underwent reconstruction in the region of dorsal sacro-iliac...

[Somatometric and Hemodynamic Measurements after the Total Replacement of Weight Bearing Joint in Preventive Administration of Low-molecular Heparines.].

J Tkácik, P Maresch, F Makai, B Valko

Acta Chir Orthop Traumatol Cech. 1999; 66(3):152-157

The authors present outcomes of simple somatometric and impedance measurements of the condition of venous hemodynamics after the total replacement of weight bearing joints with a simultaneous prophylactic application of low molecular heparines (LMH). Measurements in a group of 125 patients (86 females and 39 males) showed increase of circumferences up to symptoms of a swelling on proximal portions of the limb operated on in an early postoperative period; as a rule it reached its peak between 6th and 8th day with a subsequent subsidence in the next period, i. e. until the dismissal of the patient from the hospital. As compared to non-operated extremities...

[Surgical technique of anterior cervical instrumented fusion.].

Z Klézl, J Fousek, I Pekný

Acta Chir Orthop Traumatol Cech. 1999; 66(3):158-164

Authors are presenting their results of anterior cervical instrumented fusion technique on group of 39 patients who were operated on in traumatic and degenerative indications.They present a 97 % fusion rate with minimal complications. Decompression of neural tissues, meticulous shaping of the tricortical autologous bone graft and respecting the physiological alignment of the cervical spine are presented as the most important steps. Application of the Morscher cervical plate is helpful, since it decreases postoperative neck immobilization in orthosis and increases the fusion rate. Key words: anterior instrumented cervical fusion, autologous bone graft,...

[Miniinvasive osteosynthesis of upper extremity fractures in children.].

P Gál, R Achácek

Acta Chir Orthop Traumatol Cech. 1999; 66(3):165-170

Over the period of 1994-1998 a total of 1,955 therapeutic surgeries in treating fractures under general anesthesia were carried out in the Pediatric Trauma Center in Brno. Of these 1,311 operations were performed in a conservative manner (67%) and 644 operations (33%) were carried out with the use of oseosynthetic material. Open reduction and fixation were performed in 121 cases (6.2%), including external fixations. Miniinvasive osteosynthesis -MIO was used in 523 cases (26.8%), of that 388 times on the upper extremity reaching 74.1% of the total number of osteosyntheses performed using this method. Short incision was carried out 19 times due to inability...

[Technique of transposition of os pisiforme in treatment kienböck disease of the lunate.].

J Pech, O Nanka, D Pokorný

Acta Chir Orthop Traumatol Cech. 1999; 66(3):171-175

The authors present an overview of surgical treatment of I-IV Degree aseptic necrosis of the lunate. They deal in detail with the transposition of os pisiforme which is indicated in compressive changes of the lunate bone in III and IV degrees of Decoulx classification. They present the surgical procedure verified on anatomical cadavers. Transposition of os pisiforme to the space left after the extirpated lunate preserves the integrity of proximal line of carpal bones, the fundamental geometrical indexes of carpus are fully restored or they are only insignificantly changed. The evaluation of the group of patients operated on by the authors will be published....

[Burch-Schneider Ring in Revision Surgery of THR.].

Z Rozkydal, M Sklenský

Acta Chir Orthop Traumatol Cech. 1999; 66(3):176-180

The authors evaluate the results of 16 revision surgeries of the hip joint with the application of Burch-Schneider ring in 3A and 3B Paprosky type of acetabular defect on average 4 years after the primary surgery. According to the subjective evaluation 9 of them were very good, 6 of them were good and 1 result was satisfactory. The average Harris Hip Score was 88 points. They did not encounter any evident or probable loosening of the cup. In all patients bone allografts were fully integrated. The new bone created under the Burch-Schneider ring can be in future used for the revision surgery, if need be. Burch-Schneider ring can be successfully used...

[ABG Cementless THR: Description of the Implant, Medium-term Results.].

P Hajný, V Stedrý

Acta Chir Orthop Traumatol Cech. 1999; 66(3):181-186

The authors present medium-term clinical results and radiographic evaluation of the implantation of cementless ABG total hip replacement. The implant is made from titanium alloy with a press-fit acetabular cup. The outer surface of the cup is coated with hydroxyapatite. Primary stability of the stem is guaranteed by its anatomical shape, secondary stability by the hydroxyapatite coating in the metaphyseal part of the implant. Evaluation covers a group of 19 patients who showed up to the clinical and radiographic follow-up. Average age at the time of implantation was 52 years (ranging between 31 and 65). The most frequent indication was in 11 cases...
