Acta Chir Orthop Traumatol Cech. 2011; 78(5):404-409 | DOI: 10.55095/achot2011/062  

PURPOSE OF THE STUDYDecompression surgery with or without fusion is the gold standard treatment of lumbar spinal stenosis, but adjacent segment degeneration has been reported as a long-term complication after fusion. This led to the development of dynamic implants like the interspinous devices. They are supposed to limit extension and expand the spinal canal at the symptomatic level, but with reduced effect on the range of motion of the adjacent segments. The aim of the present study is the evaluation of the biomechanical effects on the range of motion (ROM) of adjacent lumbar segments after decompression and instrumentation with an interspinous...

Acta Chir Orthop Traumatol Cech. 2011; 78(5):416-422 | DOI: 10.55095/achot2011/064  

PURPOSE OF THE STUDYThe reimplantation of a cemented femoral component at revision is always a challenge for the orthopaedic surgeon, particularly when the cement mantle is intact. The aim of this study was to provide evidence that the recementing of a femoral stem into the original cement mantle can be included in routine surgical procedures.MATERIAL AND METHODSA group of 104 patients with femoral stem revision, followed-up for an average of 50.2 months, were retrospectively reviewed. The outcome evaluation was focused, in the first place, on survivorship of the femoral component, acetabular migration, and dislocation and infection after...

K. GÜTTLER, I. LANDOR, P. VAVŘÍK, S. POPELKA, A. SOSNA, J. KRÁSENSKÝ

Acta Chir Orthop Traumatol Cech. 2011; 78(5):423-430 | DOI: 10.55095/achot2011/065  

PURPOSE OF THE STUDYTotal elbow arthroplasty is associated with a higher occurrence of complications than is usual for large-joint replacements. Two kinds of prostheses, unconstrained and semi-constrained, are currently used and each has its supporters or opponents. In this study the results of the two techniques used in our patients are evaluated and compared.MATERIALTwo groups of elbows in patients with rheumatoid arthritis were evaluated. One comprised 58 elbows treated by Souter-Strathclyde total elbow arthroplasty (S-S group). The mean age of the patients at the time of surgery was 53 years (range, 22 to 71) and the mean follow-up...

P. SUCHOMEL, J. HRADIL

Acta Chir Orthop Traumatol Cech. 2011; 78(5):437-441 | DOI: 10.55095/achot2011/067  

PURPOSE OF THE STUDYTo present a new technique of minimally invasive decompression of the cervical spinal canal using elastic and plastic deformation of the laminae.MATERIAL AND METHODSShort midline vertical incision provides an access to the superior aspect of the target spinous processes. Cranial edge of the lamina is located by a midline, muscle-sparing interspinous dissection. The spinous process is cut in mid-sagittal plane using a thin blade of an ultrasonic bone scalpel down to epidural space. The created sagittal cleavage of the spinous process is subjected to tension and elastic distraction by a custom-designed distractor (Aesculap,...

Acta Chir Orthop Traumatol Cech. 2011; 78(5):442-446 | DOI: 10.55095/achot2011/068  

PURPOSE OF THE STUDYOsteoporotic vertebral fractures can be treated by minimally invasive percutaneous vertebral augmentation with bone cement using vertebroplasty or balloon kyphoplasty. Transcutaneous reduction and vertebral body stenting has been the most recent principle. In contrast to balloon placement in kyphoplasty, the stent remains in the vertebral body and supports both the vertebral body and cement filling. In this retrospective study we present the essential information on the method and our first results.MATERIAL AND METHODSThe method of vertebral body stent placement was used in 22 patients treated at 29 levels. Of these,...

Reduction of Radiation Exposure by the Use of Fluoroscopic Guidance in Transpedicular InstrumentationOriginal papers

R. HART, M. KOMZÁK, R. BÁRTA, F. OKÁL, E. ŠRŮTKOVÁ

Acta Chir Orthop Traumatol Cech. 2011; 78(5):447-450 | DOI: 10.55095/achot2011/069  

PURPOSE OF THE STUDYThe variability in width, height, and orientation of spinal pedicles makes pedicle screw insertion a delicate operation. Fluoroscopic guidance often exposes the patient and especially surgeons to relatively high doses of ionising radiation. The use of pulsed fluoroscopy is safer, as compared to continuous fluoroscopy, because of reduced radiation exposure. There are increasing numbers of literature reports regarding the high doses of radiation to which orthopaedic and spine surgeons are exposed during surgical procedures. Spine surgery can be associated with significant radiation exposure to the surgical staff. The purpose of...

V. NEUHAUS, J. B. JUPITER

Acta Chir Orthop Traumatol Cech. 2011; 78(5):395-403 | DOI: 10.55095/achot2011/061  

An overview about current concepts in treating carpal injuries is presented. These injuries are more commonly seen in young, active individuals after a fall on an outstretched hand. Conventional radiographs and a thorough examination are important. The scaphoid is the most affected bone. Scaphoid fractures can be classified in accordance to OTA, AO, and other classification systems, but mostly to Herbert. It can be treated non-operatively if undisplaced, however a percutaneous internal fixation can be discussed to achieve earlier return to work and shorter time to union, but hazarding the consequences of an operation. Unstable, proximal pole, or delayed...

Lumbo-Pelvic Stabilisation following Subtotal Sacrectomy due to a Giant Invasive Schwannoma. Case ReportCase report

P. HANINEC, R. KAISER, J. SKÁLA-ROSENBAUM

Acta Chir Orthop Traumatol Cech. 2011; 78(5):458-462 | DOI: 10.55095/achot2011/071  

The case of a rare giant invasive schwannoma of the sacrum is presented. This is a slow-growing tumour reaching a large size because of non-specific symptoms. Even though it is benign in nature, it has characteristics markedly differing from commonly-known neurinomas; it invades and destroys bone, on MR examination it shows a heterogeneous structure reminiscent of a malignant process and its growth around the nerve roots makes nerve dissection in the cauda equina very complicated. At the time of diagnosis a major part of the sacral bone is usually destroyed and nerve root dissection is very difficult.In this case, because of removal of most of...

Solitary Distal Femoral Osteosarcoma in 89-year-old woman. Case reportCase report

J. DRÍMAL, K. ADAMICOVÁ, L. NEČAS

Acta Chir Orthop Traumatol Cech. 2011; 78(5):463-467 | DOI: 10.55095/achot2011/072  

The authors describe the case of an 89-year-old patient with a one-month history of pain in the right knee and a pathological fracture of the distal femur. Excisional biopsy showed a classical osteogenic sarcoma. The patient died after six months of palliative surgical and oncological therapy; her primary disease generalised and progressed with numerous metastases. The authors discuss the possibilities of histological diagnostics of osteogenic sarcoma and its differential diagnosis. They draw attention to a possible occurrence of this type of sarcoma also in elderly patients, and not only in adolescents.

C-Sign and Talocalcaneal CoalitionCase report

Ľ. TOMČOVČÍK

Acta Chir Orthop Traumatol Cech. 2011; 78(5):468-471 | DOI: 10.55095/achot2011/073  

Talocalcaneal coalition is an abnormal bridge between talus and calcaneus, causing pain and restriction of subtalar movement; its incidence is less than 1 %. The signs and symptoms usually become manifest in the second decade of life with ossification of the lesion. They involve flat foot, peroneal muscle spasm, tarsal tunnel syndrome, or valgus tilt of the heel. The sings need not be noticeable and may appear only as tiredness and vague pain in the hind foot after exercise or an easily twisted ankle. The authors describe the case of talocalcaneal coalition in a 20-year-old man, incidentally diagnosed at ankle fracture. The presence of C-sign led to...
