Comparison of Short Uncemented Metaphyseal Stem and Long-Stem Reverse Shoulder Arthroplasty in Proximal Humerus Fractures: Preliminary Study at 2-Year Follow-Up.

: In the last few years, short metaphyseal-socket prosthetic humeral stems have been introduced for reverse shoulder arthroplasty (RSA). A short stem may have advantages in humeral force distribution, reducing shear stress and preserving bone stock, keeping in mind the need for possible future revision surgery. The main objective of our study was to validate the use of a short stem prosthesis in the surgical treatment of humeral fractures by comparing clinical and radiological outcomes of our studied implant with those obtained with the use of traditional long-stem implants.

Challenges in Total Hip Arthroplasty with Prior Spinal Arthrodesis: A Comprehensive Review of Biomechanics, Complications, and Surgical Strategies.

Total hip arthroplasty (THA) has revolutionized patients' lives with hip osteoarthritis. However, the increasing prevalence of THA in individuals with prior lumbar arthrodesis (LA) poses unique challenges. This review delves into the biomechanical alterations, complications, and surgical strategies specific to this patient subset, highlighting the need for tailored preoperative assessments and planning.

Should megaprosthesis implants be a viable option in elderly patients after distal femur and periprosthetic distal femur fractures?-a retrospective cohort study.

Background: Distal femur fractures (DFF) and periprosthetic distal femur fractures (PDFF) in elderly patients are challenging to manage, often requiring the use of distal femur replacement (DFR) implants to manage severe bone loss and comminution. The study's main purpose was to analyze outcomes and complications of DFR implant after DFF or PDFF at our institution to understand the feasibility and reliability of this treatment considering a review of the current literature.

Methods: Fourteen consecutive patients undergoing total knee replacement with megaprosthesis implant from January 1st, 2017 to January 1st, 2021, at our institution were retrospectively analyzed.

Outcomes of modular stem for the treatment of periprosthetic femoral fracture: a systematic review of the literature.

Background: Periprosthetic femoral fractures (PFFs) are a frequent complication after total hip arthroplasty (THA). Both modular and non-modular tapered fluted titanium (TFT) stems could be used in total hip revisions (THRs). Nevertheless, the most appropriate femoral stem type is still under debate.

Metallosis in Sequelae of Prosthetic Revision for Ceramic Components Fracture: A Case Report with Clinical Presentation Mimicking Periprosthetic Hip Infection.

Ceramic on ceramic total hip arthroplasties have been developed and widely used during last decades because of their long-term survival and biomechanical properties. One of the most dangerous complication of these implants is the fracture of the ceramic components. The management of this condition should be carefully planned and the choice of the new implant is crucial.

Combined simple elbow dislocation and forearm joint injuries. A systematic review of the literature with injury patterns and current treatment rationale.

Introduction: Recent studies have allowed a great improvement in understanding elbow and forearm traumatic injuries. Simple elbow dislocations combined with forearm injuries have been occasionally reported in the literature. The aim of this study was to detect the possible patterns of simple elbow dislocations and forearm fracture-dislocations, providing a classification scheme to guide surgical treatment.

3D-Printed Surgical Guiding System for Double Derotational Osteotomy in Congenital Torsional Limb Deformity: A Case Report.

Case: A 19-year-old woman with persistent anterior knee pain was diagnosed with a complex tibial and femoral torsional deformity (26° of femoral anteversion and 49° of tibial external rotation). To achieve the correct realignment of the lower limb, rotational double osteotomies were needed. After planning the correction on the computed tomography scan and three-dimensional (3D) model, a custom-made 3D-printed guiding system was produced to support the surgery.

Perspectives and Consensus among International Orthopaedic Surgeons during Initial and Mid-lockdown Phases of Coronavirus Disease.

With a lot of uncertainty, unclear, and frequently changing management protocols, COVID-19 has significantly impacted the orthopaedic surgical practice during this pandemic crisis. Surgeons around the world needed closed introspection, contemplation, and prospective consensual recommendations for safe surgical practice and prevention of viral contamination. One hundred orthopaedic surgeons from 50 countries were sent a Google online form with a questionnaire explicating protocols for admission, surgeries, discharge, follow-up, relevant information affecting their surgical practices, difficulties faced, and many more important issues that happened during and after the lockdown.

All-inside technique in ACL reconstruction: mid-term clinical outcomes and comparison with AM technique (Hamstrings and BpTB grafts).

Purpose: The aim of this study was to define the subjective and objective clinical results of all-inside surgical technique at a medium-term follow-up and to compare these results with those obtained from antero-medial (AM) ACL reconstruction technique using hamstrings (HS) or bone-patellar tendon-bone (BpTB) grafts to detect eventual superiority of one technique to another.

Methods: A retrospective analysis of routinely collected data was conducted. Inclusion criteria were ACL reconstruction through all-inside technique or AM technique with HS or BpTB performed between January 2015 and May 2018; age between 15 and 30 year old; minimum 24 months' available follow-up.

One bone forearm with vascularized fibular graft. Clinical experience and literature review.

One-Bone-Forearm (OBF) is a procedure in which the proximal stump of the ulna is fixed to the distal stump of the radius. Historically, the indications for OBF have been represented by forearm instability due to trauma, infection, tumor resection, and congenital deformities with severe radius and ulna bone loss. When major bone loss prevents direct fixation between ulna and radius a Vascularized Fibular Bone Graft (VFBG) may allow forearm bone reconstruction and fixation.

Sarcopenia in distal radius fractures: systematic review of the literature and current findings.

Introduction: Sarcopenia is a clinical syndrome characterized by the reduction in muscle mass, strength and physical ability. Although proximal femur fractures are one of the major burdens affecting the ageing population, distal radius fractures are equally important for frequency, clinical and social consequences. The aim of this study is to evaluate the incidence of sarcopenia in distal radius fractures and clinical implications in functional recovery.

A Preliminary Study on the Mechanical Reliability and Regeneration Capability of Artificial Bone Grafts in Oncologic Cases, With and Without Osteosynthesis.

Several bone grafts are available for clinical use, each with their own peculiar biological and mechanical properties. A new bone graft was obtained by combining mineral structures from natural bovine bones with bioresorbable polymers and cellular nutrients. The study aims to evaluate the clinical, biological and structural properties of this bone graft and its reliability in orthopedic oncology.

Long-term results of Zweymüller SLL femoral stem in revision hip arthroplasty for stage II and IIIA femoral bone defect: a 9-15-year follow-up study.

Background: Loosening of femoral stem can be associated with a wide spectrum of bone loss that represents the most important factor for choosing the most appropriate revision implant. Positive outcomes in femoral revision were already observed with Zweymüller Alloclassic SLL stem in short- and medium-term follow-up. The aim of the study is to analyse the clinical results of 31 patients who underwent prosthetic revision for aseptic loosening of femoral component with Zweymüller femoral stem and long follow-up.
