Objective Medial meniscal extrusion is known to be related structural progression of knee osteoarthritis. However, it unclear whether medial more strongly associated with cartilage loss in certain femorotibial subregions than others. Methods Segmentation the tibial and femoral (baseline; 1‐year followup) meniscus (baseline) was performed 60 participants frequent pain (mean ± SD ages 61.3 9.2 years, body mass index 31.3 3.9 kg/m 2 ) unilateral radiographic joint space narrowing (JSN) grades...

Little scientific evidence on blood loss and transfusion rates after short-stem hip arthroplasty exists. The hypothesis of this study was that the rate is lower in short stems compared to straight stems. We 124 patients who underwent total (THA) using a design (group 1) 141 straight-stem 2). All were operated by same surgeon, both groups similar age, gender, affected side, body mass index, ASA score. calculated 1139 ml group 1 1358 2 (p < 0.001). 8% 15.6% There no significant difference...

Rotator cuff tear arthropathy (CTA) is the most common reason for reverse total shoulder arthroplasty (RSA). There minimal understanding of natural progression osteoarthritis and morphologic differences between men women younger older patients. This trial comprised 309 patients (342 shoulders) who underwent RSA due to CTA in period January 2009 September 2019. The were divided into gender age groups. Preoperative X-rays, computed tomography magnetic resonance imaging conducted using various...

In a prospective, randomized, assessor-blind multicentre study two antithrombotic subcutaneous regimens were compared in patients undergoing total hip replacement. Group 1 (154 patients) received 750 anti-Xa units of new low molecular weight heparinoid (Lomoparan) subcutaneously twice day and group 2 (155 5000 heparin 0.5 mg dihydroergotamine (heparin-DHE 5000) day. The incidence deep vein thrombosis, assessed by routine bilateral venography on 10 (+/- 1), was 17 32 per cent groups...

Synovial hemangioma is a rare condition and frequently misdiagnosed, leading to diagnostic delay of many years.We present case an atypical synovial in 12-year-old Caucasian boy with 3 years.It important know that mostly affects the knee joint, showing recurrent bloody effusions without history trauma. If there are no intermittent effusions, diagnosis will be even more difficult. In cases nonspecific symptoms longstanding pain should also considered order avoid delay. Magnetic resonance...

Information about sport activity after short-stem total hip arthroplasty (THA) is scarce in the literature. We therefore aimed to evaluate rate of return THA.

Abstract Background Severe acetabular defects require special treatment with either impaction bone grafting, metal augmented cups or cup-cage constructs. Even these options are often not adequate, especially in hips Paprosky type 3 loss of anterior and posterior columns. This study investigates the clinical radiological outcomes custom-made components (© Materialise NV, Leuven, Belgium) for defects. Methods Sixteen patients were eligible this trial, nine whom agreed to be included. All them...

Acromial Levy III fractures after inverse shoulder arthroplasty occur in up to 7% of patients. To date, it is not clear how these should be treated as clinical outcomes remain unsatisfactory. The aim this study was evaluate the biomechanical performance three different plating methods type acromion fractures.

In a randomised study we have evaluated the influence of erythropoietin (EPO) on yield autologous blood in elective surgery (total hip replacement). The was performed placebo controlled 82 patients: 25 patients received 200 IE EPO/kg 2 x/week i.v. over 3 weeks (group C), 30 100 EPO same schedule B), and 27 A). All were treated with x 250 mg Fe-sulfate p.o. during time. number collected conserves not significantly different these groups (5.4 group C, 5.06 B, 4.8 A), but there significant...

The purpose of this study was to evaluate sleep disturbance prospectively before and after short-stem hip arthroplasty.A prospective on 25 patients undergoing a primary unilateral total replacement conducted. Patients were observed for six months. To the quality daytime sleepiness, Pittsburgh Sleep Quality Index Epworth Sleepiness Scale used. assess general physical health status, we used Short Form 36 Health Survey (SF-36). Pain recorded visual analog scale.The status improved significantly...

Contracted valgus flat foot in the adolescent is frequently caused by tarsal synostosis or synchondrosis. These synostoses are prevalently symptomatic during adolescence, when ossifying they block subtalar joint valgus. Careful and detailed examinations might reveal additional abnormalities.A 16-year-old boy of Austrian origin presented with contracted associated hypomobility pain. Talonavicular ball socket ankle was detected via lateral radiographs 3 DCT scan. Preoperative laboratory...

Abstract Background Bone stock preservation in total hip replacement is essential to allow for later revisions an increasingly younger and fitter index patient population. While contemporary modular press-fit acetabular cups lead rigid fixation with equatorial stress central osteolysis, more elastic may cause different peri-acetabular bone remodelling. The purpose of this study was investigate changes mineral density (BMD) uncemented monoblock cups. Methods This prospective observational...

Calcar-guided short stems in total hip arthroplasty (THA) permit surgeons to successfully reconstruct postoperative femoroacetabular offset, accurately restore leg length, and adequately re-establish a wide range of caput-collum-diaphyseal angles. However, their effect on femoral antetorsion is less known. Indeed, controlling the stem can be challenging because differences individual geometry curvature. Therefore, we investigated if calcar-guided short-stem THA alters compared it with...

Background: Calcar-guided short-stem Total Hip Arthroplasty (THA) is increasingly being used to preserve proximal femoral bone stock for potential later revision surgery. Objective: In this study, we aimed expand the clinical evidence on calcar-guided THA in daily practice, focusing outcomes as well radiographic signs of stress shielding and loss. Methods: a prospective multicentre enrolled 213 patients with total 224 THAs mainly degenerative indications. The were examined clinically...

Musculoskeletal surgery is associated with a high risk of venous thrombosis and pulmonary embolism. The introduction direct oral anticoagulants (DOAK) has broadened the possibilities for prevention thromboembolism in course orthopedic trauma surgery. Addressing this recent development, Austrian Societies Orthopedics Orthopedic Surgery (ÖGO), Trauma (ÖGU), Hematology Oncology (OeGHO) Anaesthesiology, Reanimation und Intensive Care Medicine (ÖGARI) have taken initiative to create guidelines...

The aim of the present study was to evaluate clinical and radiographic results primary total hip arthroplasty (THA) performed with Alloclassic Variall system (a modified version Zweymüller system) compare them those in literature for original system.Between January 2001 December 2002, 273 consecutive THAs were 259 patients at a single centre system, using ceramic-on-ceramic (81.7 %) or ceramic-on-highly-crosslinked-polyethylene (18.3 articulations.At time this study, 28 (29 hips; 10.6 had...
