Clinical Outcomes of Lapidus Arthrodesis With Nitinol Staples for Hallux Valgus Correction.

Background: This study evaluated postoperative outcomes following Lapidus arthrodesis (fusion of the first tarsometatarsal joint [TMT1]) using two nitinol staples for hallux valgus correction, focusing on fusion rate, reoperation rate, and patient satisfaction.

Methods: A total of 60 cases undergoing Lapidus arthrodesis between June 2018 and June 2022 were analyzed with a median follow-up of 37 months (range: 15-64 months). All cases were treated using two nitinol staples (BME Elite; DePuy Synthes) for TMT1 fusion.

Allograft Bone Screw in a Comminuted Hawkins III Talar Neck Fracture: Case Report.

Talar neck fractures are complex injuries that become particularly challenging when accompanied by bone loss or comminution. This case report introduces the use of an allograft bone screw as a novel method for bridging lateral comminution at the talar neck, providing structural support and promoting bone regeneration. : A 20-year-old male sustained a comminuted talar neck fracture with subtalar and tibiotalar dislocation after a bouldering fall.

Evaluation of a radiological grading system for the early detection of total knee arthroplasties at risk for revision surgery.

Introduction: X-rays are regularly performed after primary total knee arthroplasty (TKA). While soft tissue management and ligament tension cannot be evaluated, important information, such as inadequate component positioning and loose cement location, as well as subsequent loosening, can be detected. The aim of this study was to correlate radiological findings, referring to the radiological grading system (previously published by the same study group, henceforth abbreviated as "RGS"), with long-term outcomes and implant survival.

Non-Union Treatment in the Foot, Ankle, and Lower Leg: A Multicenter Retrospective Study Comparing Conventional Treatment with the Human Allogeneic Cortical Bone Screw (Shark Screw).

Addressing non-unions involves stabilizing the affected area through osteosynthesis and improving bone biology using bone grafts. However, there is no consensus on the optimal treatment method. This study aims to compare outcomes of non-union surgery using conventional treatment methods (metal hardware ± graft) versus osteosynthesis with the human allogeneic cortical bone screw (Shark Screw) alone or in combination with a metallic plate.

Simplified Pain Management Including Fentanyl TTS in PACU Patients With Hip Fracture Surgery to Improve Patients' Well-Being: A Double-Blind Randomized Trial.

Purpose: Adequate pain management is eminently relevant for elderly and more vulnerable patients with hip fractures in the setting of pre and postoperative pain. This study compares postoperative hip fracture patients treated with standard pain management with a variety of medications or an approach with only one option in each medication category (nonopioid: acetaminophen; opioid: fentanyl TTS 12,5 mcg/hour; rescue medication: piritramide) to simplify the treatment algorithm for nurses and improve patient well-being.

Design: Double-blind randomized controlled trial.

Mg-Zn-Ca Alloy (ZX00) Screws Are Resorbed at a Mean of 2.5 Years After Medial Malleolar Fracture Fixation: Follow-up of a First-in-humans Application and Insights From a Sheep Model.

Background: In the ongoing development of bioresorbable implants, there has been a particular focus on magnesium (Mg)-based alloys. Several Mg alloys have shown promising properties, including a lean, bioresorbable magnesium-zinc-calcium (Mg-Zn-Ca) alloy designated as ZX00. To our knowledge, this is the first clinically tested Mg-based alloy free from rare-earth elements or other elements.

[Sterile puncture of large joints].

Objective: Puncture of large joints is performed for diagnostic purposes on the one hand and for the treatment of joint pathologies on the other. Puncture can be used for rapid pain relief by relieving effusions or intra-articular hematomas. The obtained puncture specimen allows immediate visual assessment and subsequent microscopic-cytological and microbiological evaluation in the laboratory.

Osteotomy after medial malleolus fracture fixed with magnesium screws ZX00 - A case report.

Magnesium alloys have recently become the focus of research, as these implants exhibit suitable biocompatibility and appropriate mechanical properties (Grün et al., 2018 [1]). Through intensive preclinical and clinical investigation, many questions regarding stability, biocompatibility and degradation behavior have been answered (Holweg et al.

Combined femoral and popliteal nerve block is superior to local periarticular infiltration anaesthesia for postoperative pain control after total knee arthroplasty.

Introduction: After primary total knee arthroplasty (TKA), local periarticular infiltration anaesthesia (LIA) is a fast and safe method for postoperative pain control. Moreover, ultrasound-guided regional anaesthesia (USRA) with femoral and popliteal block is a standard procedure in perioperative care. Two analgesic regimens for TKA-LIA versus URSA with dexmedetomidine-were compared as an additive to ropivacaine.

Can Hardware Removal be Avoided Using Bioresorbable Mg-Zn-Ca Screws After Medial Malleolar Fracture Fixation? Mid-Term Results of a First-In-Human Study.

Unlabelled: Ankle is the most common site of hardware removal, mainly performed within 12 months of the primary surgery. The prominence of the metallic hardware is a frequent cause of pain after fracture fixation. Over the last decade, the development of bioresorbable materials based on magnesium (Mg) has increased.

Comparison of elution characteristics and mechanical properties of acrylic bone cements with and without superficial vancomycin coating (SVC) in the late phase of polymerization.

Introduction: Antibiotic-loaded bone cements (ALBCs) are used as spacers in two-stage revision arthroplasty for periprosthetic joint infection. We previously described a new technique applying vancomycin powder coating to custom-made cements. To our best knowledge, this method of superficial vancomycin coating (SVC) has not been assessed before.

Popliteal Artery Entrapment Syndrome (PAES) in a 17-Year-Old Adolescent.

Introduction: Popliteal artery entrapment syndrome (PAES) is caused by compression of the popliteal artery (PA) due to deranged myotendinous structures. It can be asymptomatic or may present with exercise intolerance, claudication, or even limb-threatening ischemia. The clinical picture depends on the anatomy and degree of vascular compromise.

Pancreatic Fat Is Associated With Metabolic Syndrome and Visceral Fat but Not Beta-Cell Function or Body Mass Index in Pediatric Obesity.

Objective: Adolescents with obesity have increased risk of type 2 diabetes and metabolic syndrome (MetS). Pancreatic fat has been related to these conditions; however, little is known about associations in pediatric obesity. The present study was designed to explore these associations further.
