[Multiple-level instrumented anterior cervical fusion: a risk factor for pseudoarthrosis? A prospective study with a minimum of 3-year follow-up].
This prospective study with minimal 3-year follow-up was performed to compare fusion rates, course of fusion, collapse incidence and occurrence of subsidence in one- and two-level instrumented anterior cervical fusions (ACDF) and thus to proof the hypothesis that use of internal fixation decreases the risk of non-union in bi-segmental ACDFs to the same level that can be expected in mono-segmental procedure. ⋯ This study demonstrates that internal fixation used in multilevel ACDF decreases risk of pseudoarthrosis to the same level that can be expected in monosegmental procedures.

Multicenter Study[Transarticular fixation of C1-C2: a multicenter retrospective study].
Transarticular C1-2 fixation is a surgical alternative in treatment of atlantoaxial instability. Although the method provides very good immediate and long-term stability, it still involves several disadvantages. The group of patients as reported from various institutions are usually very small and hardly comparable. In order to objectively compare the results of the method, we collected the groups of patients treated in four institutions dealing with surgery of the cervical spine in Czech Republic. ⋯ Transarticular technique of instrumental atlantoaxial fusion is an effective method with multiple application in treatment of craniocervical and upper cervical spine instability. The gain of immediate stability with acceptable risk of possible complications is the major advantage of this procedure. The results of our multicentric retrospective study confirm the expected high fusion rate and are comparable to previously published reports.

[Long-term results of the Schenker cementless femoral component].
The aim of the work is to evaluate the results achieved in the group of patients with implanted Schenker cementless femoral component (Schenker, Switzerland) and discuss the method of solution of loosening of these components in the group of patients who underwent revision surgery. ⋯ A favourable clinical finding and a good integration of the cementless femoral component Schenker were recorded within the average follow-up of 12 years only in 5 patients. All of them were young at the time of surgery and had a very good quality of bone. As a conclusion authors state that in general, Schenker cementless femoral component has not proved to be successful in clinical practice. For revision surgery of the loosened Schenker cementless femoral component it is necessary to use a titanium cementless component with a surface allowing long-term osteointegration.

[Treatment of juvenile bone cysts by curettage and filling of the cavity with BAS-0 bioactive glass-ceramic material].
The aim of the study was to evaluate the long-term results of using the bioactive, glass-ceramic material BAS-0 for bone tissue replacement after removal of juvenile bone cysts by curettage. ⋯ Although the therapy of juvenile bone cysts has changed from extensive surgical procedures to less invasive techniques, the curettage of a cyst with subsequent filling of the residual cavity still remains the method of choice in selected patients. Instead of autogenous cancellous bone grafts or allogenic grafts predominantly used for this procedure, the bioactive, glass-ceramic material BAS-0 can be recommended, particularly when the cavity to be filled is located in the metaphysis of a long bone, i. e., in the region subject to great compression.

We analyzed a group of patients surgically treated for fractures of the intercondylar eminence of the tibia in the Department of Orthopedics in Pilsen between 1992 and 2002, and evaluated the results of this treatment on the basis of objective examination and comparison with the relevant literature data. We describe indications for surgical treatment and the surgical methods used, including different fixation materials. ⋯ Arthroscopy is considered the most suitable technique for the treatment of fractures of the intercondylar eminence of the tibia, because it is minimally invasive and provides a good view of the operative field. The outcome of surgery is not dependent on the fixation material used. However, metal implants, in contrast to absorbable materials, have to be removed in an additional surgical procedure.
