Implant Mismatch does not Affect Patient Outcomes in Primary Reverse Shoulder Arthroplasty.

Background: There is a paucity of literature on manufacturer mismatch in reverse shoulder arthroplasty (RSA). It is unclear if use of different implant manufacturers for the glenoid side and the humeral side influences patient outcomes in primary RSA. We hypothesize that patients undergoing primary RSA with manufacturer mismatch such that humeral and glenoid components are from different manufacturers will not experience adverse outcomes when compared to a cohort of patients with humeral and glenoid components from the same manufacturer.

Intra-rater and inter-rater reliability of a handheld myotonometer measuring myofascial stiffness of lower lumbar myofascial tissue in healthy adults.

Background: Biomechanical muscle properties, such as stiffness, can be valuable indicators of tissue health and show promise as a diagnostic and treatment measure for chronic low back pain (CLBP). The development of accessible assessment technologies, such as the MyotonPRO portable device, allows for the convenient quantification of muscle tone and stiffness changes. The aim of this study is to assess the reliability of lumbar erector spinae muscle stiffness with the MyotonPRO in healthy adults and to compare stiffness changes between prone and sitting position.

Biocompatibility and antibacterial properties of medical stainless steel and titanium modified by alumina and hafnia films prepared by atomic layer deposition.

Linear and Volumetric Polyethylene Wear Patterns after Primary Cruciate-Retaining Total Knee Arthroplasty Failure: An Analysis Using Optical Scanning and Computer-Aided Design Models.

(1) Background: Analyses of retrieved inserts allow for a better understanding of TKA failure mechanisms and the detection of factors that cause increased wear. The purpose of this implant retrieval study was to identify whether insert volumetric wear significantly differs among groups of common causes of total knee arthroplasty failure, whether there is a characteristic wear distribution pattern for a common cause of failure, and whether nominal insert size and component size ratio (femur-to-insert) influence linear and volumetric wear rates. (2) Methods: We digitally reconstructed 59 retrieved single-model cruciate-retaining inserts and computed their articular load-bearing surface wear utilizing an optical scanner and computer-aided design models as references.

The Impact of Fascial Manipulation on Posterior Shoulder Tightness in Asymptomatic Handball Players: A Randomized Controlled Trial.

This prospective study aimed to determine the impact of Fascial Manipulation by Stecco (FM) on the range of motion (ROM) of internal rotation (IR) and horizontal adduction (HADD) in asymptomatic handball players, representing significant risk factors for shoulder injuries. A randomized controlled trial was conducted, with participants randomly assigned to either the investigated group ( = 29) receiving a single session of FM or the control group ( = 27) receiving no treatment. The ROM for IR and HADD were measured before, immediately after, and one month after the FM session.

Revision total en bloc spondylectomy for a recurrent aggressive vertebral haemangioma of the thoracic spine causing progressive thoracic myelopathy with segmental kyphosis.

Vertebral haemangiomas are common amongst primary benign tumours of the spine, usually asymptomatic and discovered incidentally, whereby symptomatic cases are rare. Aggressive vertebral haemangiomas, occurring even less frequently, are characterized by their expansion, resulting in pain and neural compression symptoms. Depending on presentation and severity, several treatment options exist, and when causing progressive neurological deficit, surgical decompression and resection is warranted.

Insights into the immunological description of cryoglobulins with regard to detection and characterization in Slovenian rheumatological patients.

The detection of cryoglobulins (CG) used to diagnose cryoglobulinemic vasculitis requires strict adherence to protocol, with emphasis on the preanalytical part. Our main objectives were to introduce a more sensitive and specific protocol for the detection of CG and to characterize CG in Slovenian patients diagnosed with cryoglobulinemic vasculitis, other vasculitides, connective tissue diseases or non-rheumatic diseases examined at the Department of Rheumatology (University Medical Centre Ljubljana). Samples were routinely analyzed for the presence of CG with the protocol using the Folin-Ciocalteu reagent.

Anterior pushing technique for a broken scalpel blade in lumbar discectomy: a case report.

The presence of broken surgical blades or other surgically uncontrolled sharp and pointed objects in the disc space is a rare but potentially severe complication of posterior lumbar spine procedures. Herein, we report the case of a 59-year-old female patient with a history of lumbar decompression and interspinous process device implantation who underwent an instrumented revision of the lumbosacral junction. During the L5-S1 discectomy, the scalpel blade broke, and the broken fragment could not be retrieved through the posterior approach.

Psychometric Characteristics, Cross-Cultural Adaptation and Validation of the Slovenian Version of the Victorian Institute of Sports Assessments for Gluteal Tendinopathy Questionnaire (VISA-G).

Clinical and laboratory predictors for prosthetic joint infection within the first postoperative days following primary total hip and knee arthroplasty.

Purpose: To identify clinical and laboratory predictors for low- and high-grade prosthetic joint infection (PJI) within the first postoperative days following primary total hip/knee arthroplasty (THA/TKA).

Methods: Institutional bone and joint infection registry of a single osteoarticular infection referral centre was reviewed to identify all osteoarticular infections treated between 2011 and 2021. Among them were 152 consecutive PJI (63 acute high-grade PJI, 57 chronic high-grade PJI, and 32 low-grade PJI) who also had primary THA/TKA performed at the same institution, which were retrospectively analyzed with multivariate logistic regression and covariables.

Isolation and characterization of novel phages for therapeutic applications.

is an important opportunistic pathogen causing chronic prosthetic joint infections associated with biofilm growth. Increased tolerance to antibiotic therapy often requires prolonged treatment or revision surgery. Phage therapy is currently used as compassionate use therapy and continues to be evaluated for its viability as adjunctive therapy to antibiotic treatment or as an alternative treatment for infections caused by to prevent relapses.

Complications of surgical management of osteopetrosis. A case report of multiple surgeries performed on one patient.

Osteopetrosis is a rare form of sclerosing bone dysplasias which in some cases requires orthopedic surgical management of its complications. It is characterized by osteosclerosis, brittle bones and obliteration of the medullary cavity. Therefore, surgery in these cases is difficult and results can be compromised by postoperative complications.

Purpose: A type IX SLAP (superior labrum anterior to posterior) lesion involves 360° of the glenohumeral labrum. Only rare reports have been published analyzing the risk factors of this lesion and the success of its arthroscopic management. The aim of our study is to evaluate predisposing factors that lead to SLAP IX and to assess the clinical outcome after arthroscopic treatment.

Zirconia-Toughened Alumina Ceramic Wear Particles Do Not Elicit Inflammatory Responses in Human Macrophages.

Ten percent of patients undergoing total hip arthroplasty (THA) require revision surgery. One of the reasons for THA are wear particles released from the implants that can activate the immune defense and cause osteolysis and failure of the joint implant. The discrepancies between reports on toxicity and immunogenicity of the implant materials led us to this study in which we compared toxicity and immunogenicity of well-defined nanoparticles from AlO, zirconia-toughened alumina (ZTA), and cobalt chrome (CoCr), a human THP-1 macrophage cell line, human PBMCs, and therefrom-derived primary macrophages.
