A. SARMIENTO, L. L. LATTA

Acta Chir Orthop Traumatol Cech. 2009; 76(2):85-89 | DOI: 10.55095/achot2009/018  

Femoral bone lysis in total hip arthroplasty is thought to be primarily due to polyethylene or metal debris arising from the femoral or acetabular components. The debris appears to gradually seep into the cement/bone interface, eventually generating the chemical reaction that produces lysis. We experimented with a surgical technique that attempts to construct a proximal bony barrier preventing migration of debris. Following the injection of the acrylic cement and the insertion of the femoral component, but prior to complete polymerization of the cement, bone chips are pressed over the cement, in contact with the viable femoral cortex. The bone chips...

Acta Chir Orthop Traumatol Cech. 2009; 76(2):90-97 | DOI: 10.55095/achot2009/019  

PURPOSE OF THE STUDYTo evaluate the results of primary total hip replacement with the CLS acetabular cup at a minimum of 15 years of follow-up.MATERIAL AND METHODSA total of 105 patients, with 112 hips, undergoing hip arthroplasty with the use of CLS acetabular cup between 1991 and 1993 were evaluated. The group comprised of 33 men and 72 women with an average age of 51.3 years (range, 28 to 66) at the time of surgery. All patients received the CLS expansion cup with a polyethylene Sulen-type liner. Cemented femoral stems were used in 75 hips and uncemented CLS stems were implanted in 37 hips. Ceramic heads of the femoral component were...

Acta Chir Orthop Traumatol Cech. 2009; 76(2):98-103 | DOI: 10.55095/achot2009/020  

PURPOSE OF THE STUDYTo evaluate the results of arthroscopic capsular release for the treatment of severe frozen shoulder syndrome.MATERIALBetween 2006 and 2008, 27 patients with severe frozen shoulder syndrome were treated by arthroscopic capsular release. The average age of the patients was 54 years (range, 34 to 75), 15 were men and 12 were women. The right shoulder was operated on more frequently (16 patients). The average pre-operative flexion was 73 degrees (range, 10° to 150°) and pre-operative abduction was 56 degrees (10° to 140°). The average Constant score was 35 points.METHODSWith the patient in a lateral recumbent position,...

Acta Chir Orthop Traumatol Cech. 2009; 76(2):104-109 | DOI: 10.55095/achot2009/021  

PURPOSE OF THE STUDYRegional anaesthesia for the lower extremity distal to the ankle joint, knows as anaesthetic ankle block or foot block, involves a series of injections of local anaesthetic to block the peripheral nerves that supply innervation to the foot. Since the tibial nerve block is not always effective, the aim of this study was to design a modified technique of anaesthetic application.MATERIALThe study was carried out on 30 human cadavers provided by the Institute of Anatomy, 1^st Faculty of Medicine, Charles University in Prague, and included data on a total of 60 lower extremities.METHODSInformation about...

Mathematical Simulation of Stem/Cement/Bone Mechanical Interactions for Poldi-Čech, CF-30, MS-30 and PFC Femoral ComponentsOriginal papers

M. KOVANDA, V. HAVLÍČEK, J. HUDEC

Acta Chir Orthop Traumatol Cech. 2009; 76(2):110-115 | DOI: 10.55095/achot2009/022  

PURPOSE OF THE STUDYThe mid-term longevity of femoral components varies considerably, with some showing failure due to early aseptic loosening. Since the hip joint is subject to heavy mechanical loads, it can be assumed that the mechanical interaction of the implant, bone cement and femur will play a key role in the resultant reliability of an arthroplasty. This study was designed to examine this mechanical interaction in four femoral components different in construction (Poldi-Čech, CF-30, MS-30 and PFC) using mathematical simulation.MATERIAL AND METHODSFour stem/cement/femur 3-D mathematical models, comparable in quality, infolving the...

Method of Functional Treatment of Distal Radius FracturesOriginal papers

Acta Chir Orthop Traumatol Cech. 2009; 76(2):116-120 | DOI: 10.55095/achot2009/023  

PURPOSE OF THE STUDYTo present the method of functional treatment of distal radius fractures, and to evaluate its results in a group of 57 patients.MATERIALThe method described here was used to treat a Colles' fracture in 57 patients between 2001 and 2005. The average age of patients at the time of injury was 62 years (range, 19 to 82). The minimal interval between the end of treatment and the evaluation of the patient group was one year.METHODSThe presented method is based on the principles of functional treatment of wrist fractures, as advocated by Sarmiento et al. When the patient has been indicated for this treatment, the arm...

Acta Chir Orthop Traumatol Cech. 2009; 76(2):121-127 | DOI: 10.55095/achot2009/024  

PURPOSE OF THE STUDYSurgery for the nonunion or malunion of pelvic fractures is not common even at specialised departments. This article presents the authors' experience with this procedure, completed with case studies and a review of relevant literature.MATERIAL AND METHODSFrom 1998 to 2007, a total of 359 patients underwent surgery for pelvic trauma. In the same period, eight surgeries on nonunions or malunions of the pelvis were performed, three in men and five in women. The average age of the patients was 37.3 years (range from 15 to 68). The primary treatment included conservative therapy (two patients), external fixation (three patients)...

Acta Chir Orthop Traumatol Cech. 2009; 76(2):133-136 | DOI: 10.55095/achot2009/026  

PURPOSE OF THE STUDYTo present the results of a clinical study concerned with the evaluation of femoral head size based on intra-operative measurement during hip hemiarthroplasty.MATERIAL AND METHODSThe group studied comprised 801 patients who underwent hip hemiarthroplasty for femoral neck fracture in the period from 1997 to 2007. There were 638 women (79.7 %) and 282 men (20.3 %); the average age was 82.2 years (women, 82.2; men, 81.4). The procedure was indicated in elderly patients and was carried out under general anaesthesia or with spinal anaesthesia from the Kocher - Langenbeck approach. The diameter of a femoral head with preserved...

Navigation Techniques in Surgery of Cranio-Cervical Junction and Upper Cervical SpineCurrent concepts review

P. SUCHOMEL, J. HRADIL, R. FRÖLICH, P. BARSA, R. LUKÁŠ

Acta Chir Orthop Traumatol Cech. 2009; 76(2):137-148 | DOI: 10.55095/achot2009/027  

Spinal navigation has substantially advanced during the past ten years. Surgeons have gained sufficient skills and confidence, and have introduced this technology to the anatomically challenging region of the upper cervical spine and craniocervical junction. The detailed evaluation of individual anatomy, rational pre-operative planning and final intraoperative control improve the safety and precision of classical surgical procedures.As methods technologically evolve, indication criteria change accordingly, but the basic principles of a relevatn choice remain; these are to reduce morbidity due to its three main causes, i.e., mechanical, neurological...
