D Pokorný, D Jahoda, J Tomaides, P Vavrík, I Landor, A Sosna

Acta Chir Orthop Traumatol Cech. 2005; 72(5):277-281

PURPOSE OF THE STUDY: The aim of the study was to evaluate our seven-year experience with the anatomic, non-constrained SVL/Beznoska implant for total knee replacement.MATERIAL: A total of 374 cemented total knee replacements, using the SVL/Beznoska implant, were evaluated in 333 patients treated at the First Orthopedic Clinic Charles University in Prague, during a seven-year period. In addition, a patellar replacement was used in five of these patients. Included in the evaluation were also eight non-cemented and hybrid SVL/Beznoska implants used 6 years ago.METHODS: The aim of the study was to evaluate the results in terms of implant function....

[Pathologic proximal femoral fractures in children in an unicameral bone cyst].

P Havránek, T Pesl, J Bartonícek

Acta Chir Orthop Traumatol Cech. 2005; 72(5):282-286

PURPOSE OF THE STUDY: Proximal femoral fractures in children are rare, pathologic fractures being extremely rare. Despite many meanings these fractures are still "unsolved" there are some definite rules for treatment of true accidental injuries. Pathologic fractures are outstanding with their extremely rare incidence. The aim of the study is to overview a large clinical material, find out the incidence of this pathologic fracture, the extent and shape of the unicameral bone cyst (UBC), specific therapeutic approach, technical problems of eventual osteosynthesis, number of reoperations and sequels.MATERIAL: Altogether 49 children with 50 accidental...

[Resection hip arthroplasty--mid- and long-term results].

T Hudec, D Jahoda, A Sosna

Acta Chir Orthop Traumatol Cech. 2005; 72(5):287-292

PURPOSE OF THE STUDY: The study deals with resection hip arthroplasty, which is currently one of the principal orthopedic surgery procedures.The aim of the study was to evaluate the mid- and long-term results of resection arthroplasty carried out for different indications and to ascertain effects of the extent of proximal femur resection on the functional outcome.MATERIAL: In the period from 1979 to 2000, we carried out 159 resection hip arthroplasties for septic and aseptic loosening of total hip arthroplasty (THA), septic arthritis or osteomyelitis. Of these only the patients who underwent no THA implantation or reimplantation within 2 years...

[Allograft for surgical reconstruction of the cruciate ligaments of the knee - part 1].

P Sadovský, D Musil, J Stehlík

Acta Chir Orthop Traumatol Cech. 2005; 72(5):293-296

PURPOSE OF THE STUDY: The growing numbers of anterior cruciate ligament (ACL) reconstructions performed by an increasing number of surgeons have resulted in an increased number of failed reconstructed ligaments. For repeat surgery, autologous tissues are most frequently used, namely BTB graft, hamstring tendons or quadriceps tendon construct. However, these alternative methods have certain disadvantages and therefore we decided to use BTB allografts from cadaverous donors. The risk of disease transmission due to allograft implantation has been reported to be low, but a thorough serological screening of donors is the prerequisite. We used BTB allografts...

[BTB allograft for revision surgery of the anterior cruciate ligament - part 2].

D Musil, P Sadovský, J Stehlík

Acta Chir Orthop Traumatol Cech. 2005; 72(5):297-303

PURPOSE OF THE STUDY: The study evaluates our experience with revision anterior cruciate ligament (ACL) surgery, with emphasis placed on the use of allografts.MATERIAL: In the 2002-2004 period, 421 reconstructions of the anterior cruciate ligament, using patellar BTB or hamstring tendon autografts, were carried out in our orthopedic ward. In the same period we performed 24 revision ACL reconstructions (6 %) with BTB allografts; 19 were in men and five in women. Revision surgery after ACL reconstruction with a BTB graft fixed with a non-absorbable interference screw and with a hamstring tendon graft was performed in 18 and 5 patients, respectively.METHODS:...

[Correlation of long-term clinical and radiological results after meniscectomies].

R Hart, M Janecek, V Siska, B Kucera, V Stipcák

Acta Chir Orthop Traumatol Cech. 2005; 72(5):304-307

PURPOSE OF THE STUDY: Although surgical treatment of meniscus injuries has made great progress, meniscectomy remains the most frequently indicated intervention. The aim of this retrospective study was to evaluate the long-term radiological results of isolated subtotal and total meniscectomies and compare them with the clinical results.MATERIAL: The assessed group included 22 men and 8 women at an average age of 35 years; nine and 21 knees, respectively, were treated by isolated subtotal and total meniscectomy in the period from 1987 to 1989. The lateral meniscus was operated on in six knees and the medial meniscus in 24 knees. Patients with other...

[Opening-wedge osteotomy of the proximal tibia].

R Prix

Acta Chir Orthop Traumatol Cech. 2005; 72(5):308-312

PURPOSE OF THE STUDY: The aim of this study was to evaluate the accuracy of correction and short-term outcomes of treatment by opening-wedge tibial osteotomy with the use of allograft and a modified Puddu plate fixation.MATERIAL: Between February 2001 and March 2003, 33 operations on 30 patients, at an average age of 54 years, with gonarthrosis and varus deformity were evaluated. Grade III arthritis was diagnosed in 24 knees (73 %) and grade II in nine knees (27 %).METHODS: The preoperative planning as well as intraoperative correction were based on the limb mechanical axis, as shown on an X-ray image of the whole lower extemity. Tibial osteotomy...

[Juvenile unstable severe slip of the proximal femoral epiphysis: case report and review of treatment options].

P Sponer, K Urban

Acta Chir Orthop Traumatol Cech. 2005; 72(5):313-316

The authors present the case of a severe unstable slip of the proximal femoral epiphysis in a 14-year-old boy. A serious metabolic disorder diagnosed in the boy led to postponement of necessary surgical intervention. The primary development of necrosis of the proximal femoral epiphysis during the 6 months following the slip is reported here. A good outcome was eventually achieved by three-plane valgus, flexion and derotational osteotomy of the femur at second-stage surgery. The authors emphasize the prognostic importance of stability assessment in the displaced epiphysis.

[Unilateral dislocations of the thoracic and lumbar spine].

P Sebesta, J Stulík, T Vyskocil, J Kryl

Acta Chir Orthop Traumatol Cech. 2005; 72(5):317-321

Unilateral dislocation is a trauma typical of the cervical spine. Case reports on unilateral dislocation of the thoracic or lumbar vertebrae can be found in the relevant literature only rarely and they often describe this condition associated with multiple trauma or combined injuries. Although unilateral dislocation is an unstable injury with rotation involved, injury to the spinal cord or spinal nerve roots is not common. Diagnosis is based on radiographic and CT examination. Therapy includes open reduction and instrumented spondylodesis of the injured segment. The cases of two patients with unilateral dislocations in the thoracic and the lumbar spine,...
