Colitis as the Main Presentation of COVID-19: A Case Report.

The main symptoms of coronavirus disease (COVID-19) are fever, cough, tiredness, and loss of smell and taste. Gastrointestinal symptoms are less common. A 38-year-old female patient, previously healthy, presented with a history of hematochezia up to 8 times per day, followed by abdominal cramps, urgency, and chills for two days.

Effects of Propofol on Cellular Bioenergetics in Human Skeletal Muscle Cells.

Objectives: Propofol may adversely affect the function of mitochondria and the clinical features of propofol infusion syndrome suggest that this may be linked to propofol-related bioenergetic failure. We aimed to assess the effect of therapeutic propofol concentrations on energy metabolism in human skeletal muscle cells.

Design: In vitro study on human skeletal muscle cells.

The Influence of the Age, the Years of Training, and the BMI on the Average Muscle Power in Male and Female Rowers.

The aim of the study was to evaluate the influence of the age, the body mass index (BMI), and the years of training on the average muscle power in male and female rowers. The analysis of the testing results of the members of the Rowing club Iktus from Osijek in Croatia was performed. Results were obtained during the regular yearly testing on the rowing ergometer for the rowing season of 2009.

Fractures of the scapular neck: diagnosis, classifications and treatment.

Purpose: Fractures of the scapular, or glenoid, neck are strongly debated in the relevant literature. Analysis of the respective studies, however, revealed a considerable confusion in terms of definition, terminology and diagnosis. In addition, there are few studies, primarily case reviews, dealing in detail with these fractures.

Fractures of the anatomical neck of the scapula: two cases and review of the literature.

Anatomical neck fractures of the scapula are rare. The authors have found in the literature only four radiologically documented fractures of the anatomical neck of the scapula. Two of them were published by Hardegger et al.

[Intra-operative periprosthetic fractures during THA in the period 1995-2009].

Purpose Of The Study: The aim of this prospective study was to investigate whether female gender and revision surgery were significant risk factors for intra-operative periprosthetic fractures during total hip arthroplasty (THA).

Material And Methods: The group investigated comprised the patients who, in the period 1995-2009, sustained an intra-operative periprosthetic fracture during primary or revision THA. The patients were treated by a therapeutic procedure based on the Vancouver system.

Scapular body fractures: results of operative treatment.

The authors operated on 22 patients with scapular body fractures, with a mean age of 35 years. The minimal follow-up was 12 months. All patients were treated from the Judet posterior approach.

Displaced fractures of the medial end of the clavicle: report of five cases.

The authors present a group of five men who sustained a displaced fracture of the medial end of the clavicle. In all cases, the diagnosis was confirmed by computed tomographic scan. Three young men with extra-articular fractures were treated operatively with a very good result.

[Radiographic evaluation of scapula fractures].

The authors use both radiographic and CT examination for diagnosing fractures of the scapula. The standard trauma series consists of chest radiograph, ap radiograph of injured shoulder girdle, ap and lateral radiographs of the scapula (Neer I and II views). According to our experience, the axillary view is not very helpful.

Intraoperative reduction of the scapular body--a technical trick.

When internal fixation of the scapular neck and body fractures is performed, a problem may occur with reduction and retention of position of the lateral border of the scapula during surgery. For this purpose, the authors have developed their own technique of stabilization using a K-wire in a novel way. The technique is indicated in a 2-part shear unstable fracture of the lateral border.

[Fractures of sternal end of the clavicle--current concept review].

Fractures of the medial end of the clavicle are still an outstanding issue with only minimum information available. Their diagnosis requires a special care both in isolated fractures of the clavicle and in polytrauma. An accurate diagnosis is impossible without CT scanning, preferably with a 3D reconstruction.

[Epidemiology and economic implications of fractures of proximal femur, proximal humerus, distal radius and fracture-dislocation of ankle].

The authors analyze the results of their long-term follow-up of basic epidemiological characteristics in fractures of proximal humerus (1,464 patients), distal radius (2,514 patients), proximal femur (3,340 patients) and fracture-dislocation of the ankle (1 195 patients). In fractures of the proximal femur, the average age was 78 years; 71.6 years in men and 80.

Bosworth-type fibular entrapment injuries of the ankle: the Bosworth lesion. A report of 6 cases and literature review.

Objectives: To evaluate patients with Bosworth-type fibular entrapment injuries of the ankle.

Design: Retrospective clinical study and analysis of the literature.

Setting: University hospital.

[Diagnosing occult pertrochanteric fractures of proximal femur with MRI].

A group of 9 patients with a suspected fracture of the hip underwent radiography and subsequently magnetic resonance imaging (MRI) diagnosis. Radiographic findings were in 2 cases negative and in 7 cases the radiographs revealed a fissure or fracture of the greater trochanter. MRI proved a complete pertrochanteric fracture in 1 case, an incomplete pertrochanteric fracture in 8 cases and in all the 9 cases a fracture of the greater trochanter.

Avascular necrosis of the femoral head in pertrochanteric fractures: a report of 8 cases and a review of the literature.

Objective: To evaluate patients with pertrochanteric fractures (Type 31A1 + 2 ASIF/OTA classification) treated surgically and who subsequently developed avascular necrosis of the femoral head (ANFH).

Setting: University hospital.

Design: Retrospective clinical study and analysis of the literature.

[Unreamed locking intramedullary nailing of humeral fractures--basic evaluation of a patient group].

Purpose Of The Study: The aim of the work is to provide an overview of the existing experience in Synthes unreamed humeral nail (UHN).

Material: Between August 1996 and February 2000 we treated by means of UHN a group of 37 patients (12 men and 25 women), average age 55 years (range, 18-87 years) with a fracture of humeral shaft. According to AO classification in 10 patients it was a case of a fracture of proximal humerus involving the shaft (11B-3) and in 27 cases a fracture of the shaft (12 A, B, C).

[S-ROM Modular THR System -Three and Half Years of Experience.].

Unlabelled: PURPOSE OF THE STUDY Presentation of the first 3,5-year experience with the application of S-ROM system in total hip arthroplasty. MATERIAL A retrospective study evaluating 33 patients (14 men, 19 women), average age 57 years (25-84 years) operated on in the period betwen December 1996 and June 2000. In 5 cases we performed primary implantation and in 28 cases revision surgery.

[Endoprosthesis of the shoulder joint designed by the authors - surgical technique.].

Endoprostheses of the shoulder joint are nowadays already standard procedures in the surgical repertoir of orthopaedic and traumatological departments. Indication for the operation are degenerative diseases with destruction of the articular surface, non-reconstructible fractures of the upper end of the humerus, in particular in elderly patients and tumours in the area of the proximal portion of the humerus. The main cause of inadequate function of endoprostheses of the shoulder joint is insufficiency of the rotator cuff.

[Alloplasty of the shoulder joint - introduction to the problem.].

The authors present a review of contemporary views on the problem of alloplasty of the shoulder joint. In the historical introduction they mention the development of surgery of the shoulder joint with the gradual transition from resection or interposition arthroplasties to endoprostheses of varying design which according to the principle of internal constraint can be divided into three groups, i. e.

[Contribution to the problem of classification of fractures of the proximal end of the humerus in adults.].

A classification is useful only if it helps the surgeon to resolve a given fracture. This applies obviously also to fractures of the proximal end of the humerus. In the submitted paper the authors review the problem of classification of fractures of the proximal humerus which could help orthopaedists and traumatologists to decide on the therapeutic approach to these serious injuries.

[Initial Results with Non-cemented Walter-Motorlet Prostheses of the Hip Joint.].

The authors present their experience with the use of non-cemented total endoprostheses of the hip joint. During a 5-year period at the First Orthopaedic Clinic of the First Medical Faculty, Charles University, Prague 178 non-cemented hip joint prostheses were implanted. The authors evaluated, using internationally accepted criteria, 69 patiens with non-cemented prostheses of the hip joint Walter-Motorlet after an interval of more than 20 months.

[Results of reconstructive surgery in fractures of the proximal humerus].

In treatment of comminuted dislocation fractures of the proximal humerus the most serious therapeutic problem still remains the 6th group of Neer's classification, in particular fractures with four fragments and with a completely dislocated and devitalized head. The authors present in a retrospective study an overall comparison of results assembled in 30 patients (and 19 checked patients resp.) who were operated by the technique of anatomical reconstruction (13 and 8 patients resp.

[Long-term results of Ludloff's repositioning method].

Authors have evaluated results of the surgical treatment of congenital dysplasia of the hip joint performed at I Orthopaedic Clinic in Prague in the years 1970-1985. In the course of this period open reduction according to Ludloff was performed in seventy children out of which eight times bilaterally. Fifty-six out of the total number of seventy children same for the follow-up check.
