Periprosthetic knee joint infection caused by which was first -osteoarticular brucellosis or osteoarthrosis: A case report.

Background: Brucellosis is the most common zoonosis worldwide and is endemic in the Middle East, Africa, Asia, and Latin America. However, it is uncommon in Central Europe, and periprosthetic infections caused by are therefore rare. Due to the low prevalence and nonspecific clinical presentation of the disease, accurate diagnosis can be challenging; no gold standard currently exists for treating brucellosis.

Age- and Gender-Related Differences in the Morphology of Cuff Tear Arthropathy: A Cross Sectional Analysis.

Rotator cuff tear arthropathy (CTA) is the most common reason for reverse total shoulder arthroplasty (RSA). There is minimal understanding of the natural progression of osteoarthritis of the shoulder and of the morphologic differences between men and women and between younger and older patients. This trial comprised 309 patients (342 shoulders) who underwent RSA due to CTA in the period between January 2009 and September 2019.

Clinical and Radiological Outcomes after Total Shoulder Arthroplasty Using Custom-Made Glenoid Components: A Systematic Review.

Reverse total shoulder arthroplasty presents itself sometimes as challenging when it comes to addressing massive bone loss, either in primary or revision settings. Custom components recently have made their way into shoulder prosthetics and are meant to help in the case of extensive glenoid bone destruction. Because of strict indication and the fairly recent introduction of these implants, the usage of custom-made glenoid implants is not very common yet.

[The challenge of revising a well-fixed curved calcar-guided short stem in total hip arthroplasty: Introduction of a new curved extraction chisel system].

Objective: Safe and bone-conserving extraction of a well-fixed curved short stem without the necessity of a transfemoral approach.

Indications: The revision of a well-fixed curved short stem, for example, due to periprosthetic infection or malposition. Meticulous preparation of the cone and the lateral shoulder of the stem.

Bone Preservation in Total Hip Arthroplasty.

Background: Preserving bone stock in younger and more active patients after total hip arthroplasty (THA) is important for future revision. Newer prosthesis designs, including short femoral stems and isoelastic acetabular cups, are likely to preserve more bone stock. However, long-term follow-up studies on bone remodeling after short-stem THA with an isoelastic monoblock acetabular cup are few.

Femoral antetorsion after calcar-guided short-stem total hip arthroplasty: A cadaver study.

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 antetorsion of the femoral stem can be challenging because of the differences in individual femoral geometry and curvature.

Functional and radiological outcomes after treatment with custom-made acetabular components in patients with Paprosky type 3 acetabular defects: short-term results.

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 with Paprosky type 3 defects with loss of anterior and posterior columns. This study investigates the clinical and radiological outcomes of custom-made acetabular components (© Materialise NV, Leuven, Belgium) for Paprosky type 3 defects.

Peri-acetabular bone remodelling after uncemented total hip arthroplasty with monoblock press-fit cups: an observational study.

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

Femoral bone remodeling after short-stem total hip arthroplasty: a prospective densitometric study.

Purpose: Due to improved prosthesis designs and surgical techniques, indications for total hip arthroplasty (THA) now include younger and more active patients. Preserving bone stock and soft tissue in these patients is paramount to allow for future revision. Designed for anatomical reconstruction, short femoral stems have the potential to reduce adaptive bone loss and stress shielding.

Return to sports after glenoid reconstruction using an implant-free iliac crest bone graft.

Purpose: The purpose of this study was to evaluate sports ability and the rate of return to sports after implant-free iliac bone graft for recurrent, anterior shoulder instability and anterior glenoid bone loss. Subgroups of younger and older patients and patients who had previous arthroscopic Bankart surgery and those who did not have such surgery before implant-free iliac bone graft were formed and compared.

Methods: We retrospectively analyzed 34 patients; 14 patients had previous arthroscopic Bankart surgery, and 20 patients did not have the surgery; The median age at the time of iliac bone graft was 35.

Return to Sport After Short-Stem Total Hip Arthroplasty.

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

Methods: We evaluated the sport pattern, rate of return to sport, activity level, extent of sport activity, and subjective rating and sense of well-being in 137 patients (137 hips) after short-stem THA.

Correction to: Sleep improvement after hip arthroplasty: a study on short-stem prosthesis.

Authors first and last names have been interchanged. The correct presentation is given above.

Sleep improvement after hip arthroplasty: a study on short-stem prosthesis.

Purpose: The purpose of this study was to evaluate sleep disturbance prospectively before and after short-stem hip arthroplasty.

Methods: A prospective study on 25 patients undergoing a primary unilateral total short-stem hip replacement was conducted. Patients were observed for six months.

Quantitative in vivo assessment of bone allograft viability using F-fluoride PET/CT after glenoid augmentation in reverse shoulder arthroplasty: a pilot study.

Background: Success after glenoid bone augmentation in total shoulder arthroplasty depends on osseous integration and non-resorption. Standard imaging techniques, such as computed tomography (CT) and X-rays, cannot quantify bone viability. Therefore, we introduce a new technique to assess graft viability using F-sodium fluoride (F-NaF) PET-CT for femoral allografts in reverse total shoulder arthroplasty (RSA).

Blood loss and transfusion rate in short stem hip arthroplasty. A comparative study.

Purpose: Little scientific evidence on blood loss and transfusion rates after short-stem hip arthroplasty exists. The hypothesis of this study was that the blood loss and transfusion rate is lower in short stems compared to straight stems.

Methods: We compared 124 patients who underwent total hip arthroplasty (THA) using a short-stem design (group 1) and 141 patients using a straight-stem design (group 2).

Long-term follow-up of primary total hip arthroplasty with the Alloclassic Variall system.

Purpose: The aim of the present study was to evaluate the clinical and radiographic results of primary total hip arthroplasty (THA) performed with the Alloclassic Variall system (a modified version of the Alloclassic Zweymüller system) and to compare them with those in the literature for the original system.

Methods: Between January 2001 and December 2002, 273 consecutive primary THAs were performed in 259 patients at a single centre with the study system, using ceramic-on-ceramic (81.7 %) or ceramic-on-highly-crosslinked-polyethylene (18.

[Prevention of venous thromboembolism in musculoskeletal surgery].

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

Infraglenoidal scapular notching in reverse total shoulder replacement: a prospective series of 60 cases and systematic review of the literature.

Background: The impact of infraglenoidal scapular notching in reversed total shoulder arthroplasty (RTSA) is still controversially discussed. Our goal was to evaluate its potential influence on subjective shoulder stability and clinical outcome. We hypothesized that subjective instability and clinical outcome after implantation of RTSA correlates with objective scapular notching.

Impact of previous rotator cuff repair on the outcome of reverse shoulder arthroplasty.

Background: Our purpose was to evaluate the outcome of the Delta reverse shoulder prosthesis (DePuy France, Saint Priest, France) in a consecutive series of 68 shoulders and perform a comparison of patients with and without previous shoulder arthroscopy for cuff tear reconstruction.

Patients And Methods: We assessed 68 shoulders in 66 patients (36 women and 30 men) with a mean age of 66 years (range, 53-84 years), first preoperatively and then at a minimum of 2 years' follow-up, using the Constant score for pain; Constant Shoulder Score; Oxford Shoulder Score; University of California, Los Angeles shoulder rating scale; and Disabilities of the Arm, Shoulder and Hand score. Any complications were assessed according to Goslings and Gouma.

Synovial hemangioma of the knee joint in a 12-year-old boy: a case report.

Introduction: Synovial hemangioma is a rare condition and is frequently misdiagnosed, leading to a diagnostic delay of many years.

Case Presentation: We present a case of an atypical synovial hemangioma in a 12-year-old Caucasian boy with a diagnostic delay of 3 years.

Conclusion: It is important to know that synovial hemangioma mostly affects the knee joint, showing recurrent bloody effusions without a history of trauma.

Ball and socket ankle joint in connection with bilateral tarsal synostosis in a boy with congenital absence of the portal vain: a novel malformation complex.

Background: Contracted valgus flat foot in the adolescent is frequently caused by tarsal synostosis or synchondrosis. These synostoses are prevalently symptomatic during adolescence, when by ossifying they block the subtalar joint in valgus. Careful and detailed examinations might reveal additional abnormalities.

Fractures of cementless thin-walled cups.

Cementless threaded cups are commonly used in total hip arthroplasty. A method to match the elasticity of the cup to that of natural bone is reducing the wall thickness of the implant. Despite good results with this philosophy of implantation, we recently observed 3 cases of implant fractures after the implantation of such thin-walled cups called "Bicon.
