[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.

Less invasive stabilization system (LISS) in the treatment of distal femoral fractures.
The treatment of distal femoral fractures has been associated with a high rate of complications for a long time. Although implants and surgical techniques have improved, plate osteosynthesis and intramedullary nailing have been accompanied by a high occurrence of infection, non-union and malalignment. The treatment of soft tissue envelopes using "biological" osteosynthesis and minimally invasive approaches has resulted in a decrease in complication rates and ultimately led to the concept of the less invasive stabilization system (LISS). ⋯ Infection, delayed union and non-union rates are low, as shown by yet unpublished data from our clinic. Primary bone grafting, which is rarely necessary with this system, is carried out only when there is a great bone loss. Implant failure, such as screw loosening or secondary malalignment, is not seen.

[Current diagnostic and therapeutic approaches in liver injuries].
The recent improvements in hospital care system (centralized specialized care) and the use of new imaging methods and modern technologies in surgical treatment have greatly enhanced successful outcomes of therapy in liver injury. The aim of the study was to evaluate the contribution of procedures included in the diagnostic-therapeutic algorithms to the treatment of blunt injury to the liver in our patient population. ⋯ 1. The treatment strategy in a patient with blunt liver trauma is determined by the patient's hemodynamic status; in a stable patient, spinal CT examination of the thorax and abdomen is mandatory. 2. Urgent laparotomy is indicated when the patient with blunt liver trauma is hemodynamically unstable due to diagnosed hemoperitoneum or suspected intraperitoneal bleeding. 3. Conservative therapy is applied when the criteria for non-surgical treatment are fulfilled. 4. Surgical strategy for blunt liver trauma is based on the extent and localization of the injury, the patient's overall status and severity of associated injuries. Resection of the injured parenchyma is indicated when laceration of a liver lobe occurs. 5. The prognosis of blunt liver injury is influenced, apart from hemorrhagic shock reversibility, by the severity of associated injuries in multiple trauma.

The authors present their 10-year experience with the computed tomography (CT) assisted insertion of implants in the sacroiliac (SI) region and acetabular region. Indications for these interventions and their detailed descriptions are reported. ⋯ The CT-guided surgical procedure allows us to assess both the shape and course of fracture lines or distance between the injured structures. It also enables us to choose the optimal direction, in relation to these structures, for an implant to be inserted and to respect important anatomical structures in the surroundings. It helps us to determine the exact length of implants to be used. During the procedure, repeated CT scans facilitate checking the direction and position of both instruments and implants. In the closing phase of the operation, it is possible to assess closeness of the bones screwed together, the definitive placement of the implants and their reliable fixation. This method also permits to check whether a screw did not penetrate through the opposite cortical bone.
