Is surgical treatment better than non-surgical treatment for proximal humeral fracture in elderly people? A meta-analysis and meta-regression.

Purpose: This systematic review, meta-analysis, and meta-regression aims to determine whether surgical treatment for proximal humeral fractures is superior to non-surgical treatment regarding pain, functionality, complications, and new surgery rates.

Methods: We systematically reviewed clinical trials from PubMed (MEDLINE), EMBASE, Web of Science, Scopus, and Cochrane up to April 2024. Data comparing surgical or conservative of proximal humeral fractures were retrieved for outcomes of pain, functionality, adverse events, and new surgeries.

A tension system for angular correction of bent intramedullary nails: in vitro analysis.

Purpose: Although several techniques have been described for bent intramedullary nail removal, there is no universally accepted strategy. We hypothesized that a device based on the action principle of a three-point bend fixture could facilitate extraction of bent intramedullary nails; this paper describes its design and experimental testing.

Methods: Five large synthetic left femurs and five steel intramedullary nails were used.

Modified-tension band suturing: 'the pulling the reins technique' - a technique for displaced proximal humeral fracture with medial column instability.

Fractures of the proximal humerus with medial column instability are challenging and present an unacceptable rate of complications and reoperations. Despite good results reported with the use of locking plates and augmentation techniques using bone graft or a second plate, varus subsidence and fixation failure have been frequently reported. We describe the case of a patient presenting with a complex, multifragmentary proximal humerus fractures successfully treated with open anatomic reduction and internal fixation using a locking plate augmented with lateral traction using three bone anchors in the humerus head.

Standing on shoulder of giants: the incredible legacy of the Judet family in orthopaedic surgery.

In orthopaedic surgery, as well as other areas in medicine, it is common for a surgical technique to carry the original authors' name describing the procedure. The Judet family represents a unique history, since several orthopaedic procedures are known as "Judet's technique". The aim of this historic review is to outline the genealogy of the orthopaedic arm of the Judet family, while crediting each surgical procedure to the specific family member that described the technique.

Biomechanical Efficacy of Three Methods for the Fixation of Posterior Malleolar Fractures: A Three-Dimensional Finite Element Study.

We investigated the biomechanical behaviour of different fixations of the tibial posterior malleolus (TPM), simulating distinct situations of involvement of the tibiotalar articular surface (TTAS) through a finite element model (FEM). A 3D computer-aided design model of the left ankle was obtained. The materials used were divided according to their characteristics into ductile and non-ductile, and all materials were assumed to be linear elastic, isotropic, and homogenous.

Predictive and protective factors for allogenic blood transfusion in total knee arthroplasty. A retrospective cohort study.

Background: This study aimed to identify the predictive and protective factors of blood transfusion in patients undergoing total knee arthroplasty (TKA) and therefore determine the profile of patients with low and high risk of blood transfusion after arthroplasty.

Methods: We conducted a retrospective study with all patients who underwent primary TKA between January 2017 and December 2019 (n = 1.028 patients) in our institution.

Morphological Characteristics of Proximal Ulna Fractures: A Proposal for a New Classification and Agreement for Validation.

Historically, proximal ulna fractures have been simplistically diagnosed and treated as simple olecranon fractures, leading to an unacceptable number of complications. Our hypothesis was that the recognition of lateral, intermediate, and medial stabilizers of the proximal ulna and ulnohumeral and proximal radioulnar joints would facilitate decision-making, including the choice of approach and type of fixation. The primary aim was to propose a new classification for complex fractures of the proximal ulna based on morphological characteristics seen on three-dimensional computed tomography (3D CT).

Computed Tomography Does Not Improve Intra- and Interobserver Agreement of Hertel Radiographic Prognostic Criteria.

Background and Objectives: Proximal humerus fractures are the second most frequent site of avascular necrosis (AVN), occurring in up to 16% of cases. The Hertel criteria have been used as a reference for the prediction of humerus head ischemia. However, these are based solely on the use of radiographs, which can make interpretation extremely difficult due to several reasons, such as the overlapping fragments, severity of the injury, and noncompliant acute pain patients.

Open reduction and internal fixation of Ideberg type IA glenoid fractures: Tricks, pearls, and potential pitfalls based on a retrospective cohort of 33 patients focusing on the rehabilitation protocol.

Introduction: The standard treatment of anterior glenaoid fractures carrying > 20% of the glenoid fossa is open reduction and internal fixation (ORIF). In the herein study, we report our outcomes in a retrospective cohort of anterior and anteroinferior glenoid rim fractures using an accelerated postoperative rehabilitation protocol. A secondary aim is to describe the surgical steps for ORIF of anterior and anteroinferior glenoid rim fractures using the anterior axillary approach, describing the tricks, pearls, and pitfalls of this surgical technique.

Pre-contoured superior locking plates offer poor bone fit for midshaft clavicle fracture fixation: cadaveric analysis of 4 commercially available systems.

Objective: The goal of this study is to verify how commercially available pre-contoured superior plates fit on clavicle midshaft fractures.

Methods: 100 cadaveric clavicles were evaluated by three distinct observers applying the clavicle congruence score and comparing four different 6 to 8-hole pre-contoured anatomic locking-plate systems.

Results: the inter-observer agreement was considered moderate by the percentage agreement and fair by the Fleiss' Kappa, with no significant differences between evaluations.

Infection after primary total knee arthroplasty: a randomized controlled prospective study of the addition of antibiotics to bone cement.

 The present prospective, randomized and controlled study was conducted with 286 patients submitted to primary total knee arthroplasty (TKA) with the objective of evaluating the efficacy of the addition of antibiotics to bone cement as a way to prevent post arthroplasty infection (PAI).  The patients were randomized into two groups: bone cement without antibiotic (No ATB, = 158) or cement with antibiotic (ATB, = 128), in which 2 g of vancomycin was added to 40 g of cement. The patients were followed up for 24 months after surgery.

Protocol of BRICS: Brazilian multicentric pragmatic randomised trial of surgical interventions for displaced diaphyseal clavicle fracture study: MIPO versus ORIF for the treatment of displaced midshaft clavicle fractures.

Introduction: Fractures of the diaphysis of the clavicle are common; however, treatment guidelines for this condition are lacking. Surgery is associated with a lower risk of non-union and better functional outcomes but a higher risk of complications. Open reduction and internal fixation with plates and screws are the most commonly performed techniques, but they are associated with paraesthesia in the areas of incisions, extensive surgical exposure and high rates of implant removal.

Risk factors include trauma, low-grade infection, urological or gynecological procedures, malignant tumors of the pelvis, sports, and intravenous drug abuse. This report describes a case of septic arthritis of the pubic symphysis in a 23-year-old male patient with no history of pelvic surgery, previous infections, or intense physical activity.

Current challenges and controversies in the management of scapular fractures: a review.

Fractures of the scapula are rare and usually associated with high-energy trauma. The unfavorable scapular anatomy, combined with the complexity of the approaches for fracture fixation, make the treatment challenging, even for experienced surgeons. Furthermore, the literature is controversial regarding surgical indications and rationale for treatment.

Intraoperative morphometric study of distal femur in Brazilian patients undergoing total knee arthroplasty.

Background: Total knee arthroplasty (TKA) is the treatment option for patients with severe osteoarthritis (OA) of the knee whose symptoms are refractory to conservative management. Unfortunately, the level of patient dissatisfaction is high, reaching up to 25%. The reasons for this dissatisfaction are multifactorial, but bone-implant mismatch significantly increases the chance of pain and functional limitation.

The hidden risk of ionizing radiation in the operating room: a survey among 258 orthopaedic surgeons in Brazil.

Background: This study aims to assess orthopaedic surgeon knowledge in Brazil about ionizing radiation and its health implications on surgical teams and patients.

Methods: A 15-question survey on theoretical and practical concepts of ionizing radiation was administered during the 23rd Brazilian Orthopaedic Trauma Association annual meeting. The survey addressed issues within orthopedic surgery, such as radiation safety concepts, protection, exposure, as well as the participant gender.

Positioning Technique of the Fixed Knee in Hyperflexion for the Transportal Femoral Tunnel During Reconstruction of the Anterior Cruciate Ligament.

During reconstruction surgery of the anterior cruciate ligament, the evolution of the femoral tunnel from the transtibial to the transportal path provides greater accuracy in reaching the desired anatomic point. However, there are also some new challenges, such as correct execution, reproducibility, and minimizing the risk of iatrogenic injury from its use. In an effort to overcome these challenges, we have proposed the use of a positioner, which was developed by our group and allows the leg to stay in the desired position, without variations in the operation or aid from a medical assistant.
