Optimizing management strategies for malunion and nonunion of Hoffa fractures: a detailed case series with a proposed treatment algorithm.

Purpose: This study aims to refine management strategies for malunion and nonunion of Hoffa fractures, as these rare complications present significant clinical challenges.

Methods: We conducted a case series involving seven patients with Hoffa fracture complications, including four cases of malunion and three cases of nonunion. Each patient underwent individualized surgical treatment, depending on the nature of their complication.

Do two distal locking screws in two planes offer the best option in the nailing of diaphyseal tibial fractures?

Background: Although the intramedullary nail represents the treatment for most tibia diaphyseal fractures, there is no agreement on the configuration of the distal locking screws. Therefore, this study aimed to investigate the impact of the configuration of distal locking bolts on the healing of a tibial shaft fracture.

Methods: We retrospectively analyzed 170 closed fractures of the tibia diaphyseal operated consecutively between 2018 and 2021.

Availability and use of resources for emergency fracture care of pelvic trauma associated with haemorrhagic shock in Latin America: A cross-sectional study.

Determining the true availability of resources and understanding the level of training of surgeons involved in the treatment of patients with pelvic fractures and haemorrhagic shock is critical. In the herein study, the availability of technical, technological, and human resources for the care of this injury in Latin America region was analysed, and the preferences of orthopaedic trauma surgeons when performing interventions for the diagnosis and treatment of patients with pelvic trauma and associated haemorrhagic shock was described. A cross sectional web-based survey containing questions on knowledge, attitudes, and practices with respect to imaging resources, emergency pelvic stabilization methods, and interventions used for bleeding control was sent to 948 Latin America orthopaedic trauma surgeons treating pelvic fractures in the emergency department.

Treatment of fracture-related infection in Latin America (FRILA). Proposal for a multicentre regional registry.

Postoperative bone infection is a severe complication in the treatment of fractures. The management of this pathology is challenging, but recent advances have been made to achieve standardization that can help diagnosis and decision-making. However, we are unaware of studies validating these models in Latin America.

Does the type of medial plate fixation matter for supplemental fixation of distal femur fractures manage with a lateral pre-contoured locked plate? A Biomechanical study.

Introduction: Fixation of distal femur fractures with a lateral pre-contoured locking plate provides stable fixation and is the standard treatment in most cases, allowing early range of motion with a high rate of union. However, in situations, the stability achieved with the lateral plate alone may be insufficient, predisposing to fixation failure. The objective of the study was to compare, in synthetic bone models, the biomechanical behaviour of the fixation with a distal femur lateral pre-contoured locking plate solely and associated with a 3.

Risk factors for fixation failure in intertrochanteric fractures treated with cephalomedullary nailing: a retrospective study of 251 patients.

This study aimed to identify the variables associated with fixation failure in intertrochanteric fractures treated with cephalomedullary nailing (CMN). We retrospectively analyzed 251 consecutive patients who underwent surgery between January 2016 and July 2019. In order to identify predictors of failure (cut-out, cut-through, and/or nonunion), we analyzed: gender, age, fracture stability (according to the AO/OTA Classification), femoral neck angle (FNA), FNA as compared to the contralateral hip, lag screw position, and tip-apex distance (TAD).

Antibiotic cement-coated rigid locked nails in infected femoral and tibial nonunion. Reoperation rates of commercial versus custom-made nails.

Introduction: The objective of this study is to assess bone union, infection control, and reoperation rates in a series of patients with infected femoral or tibial nonunion treated with antibiotic-cement-coated rigid nails and to compare the results obtained with custom-made nails versus commercial nails.

Methods: We retrospectively analyzed a series of consecutive patients with infected nonunion of the femur or the tibia treated with antibiotic-cement-coated rigid nails between January 2010 and 2020. We assessed patients' distinctive characteristics, initial injury, type of nail used (custom-made nail with vancomycin or commercial nail with gentamicin), success rate (bone union + infection control), reoperation rate, and failure rate.

Antibiotic cement-coated plate is a viable and efficient technique for the definitive management of metaphyseal septic nonunions of the femur and tibia.

Objective: the management of septic metaphyseal nonunions is challenging, with inconsistent outcomes. Antibiotic cement-coated implants have been demonstrated good outcome for diaphyseal infected nonunions, however there is no data in metaphyseal infected nonunions.

Methods: fifteen adult patients with septic metaphyseal nonunions of the femur or tibia were treated with antibiotic cement-coated plates.

Isolated open tibial shaft fracture: a seven-hospital, prospective observational study in two Latin America countries.

Introduction: open tibial fractures are challenging due to the frequent severe bone injury associated with poor soft tissue conditions. This is relevant in low- and middle-income countries, mainly related to delayed definitive fixation and lack of adequate training in soft tissue coverage procedures. Due to these factors, open tibial fracture is an important source of disability for Latin American countries.

Open tibial shaft fracture management in Argentina: an evaluation of treatment standards in diverse resource settings.

Background: Argentina is a country with varying access to orthopedic surgical care. The Argentine Association of Trauma and Orthopedics (AATO) "Interior Committee" was developed to address potential regional differences and promote standardization of orthopedic trauma care. The paper assesses the level of national standardization of the management of open tibia fractures across 9 provinces in Argentina.

Peri-implant femoral fractures: Challenges, outcomes, and proposal of a treatment algorithm.

Purpose: Non-prosthetic peri-implant fractures are challenging injuries. Multiple factors must be carefully evaluated for an adequate therapeutic strategy, such as the state of bone healing, the type of implant, the time and performed personnel of previous surgery, and the stability of fixation. The aim of this study is to propose a rationale for the treatment.

The relevance of the number of distal locking planes and nail to canal ratio in bone healing after intramedullary nailing in tibial shaft fractures.

Methods: We analyzed 223 consecutive tibial shaft fractures treated with reamed intramedullary nailing between January 2014 and December 2020. We recorded and evaluated the nail to canal ratio (NCR) and the number and configuration of distal locking screws.

Fragility fracture systems, Latin America perspective.

Osteoporosis is a worldwide epidemic, affecting an average of 30% to 50% of those over 50 years of age in Latin America. Resulting from it is another epidemic, that of fragility fractures, which adversely affects morbidity and mortality of this population. Increasing in their incidence, fragility fractures are expected to occur in 1 in 3 women and 1 in 5 men over 50years of age during their lifetimes.

Safety and efficacy of a novel retrograde route for femoral bone graft harvesting by Reamer-Irrigator-Aspirator: a pilot study on 24 patients.

Background: The Reamer-Irrigator-Aspirator system was initially developed to reduce fat embolism and thermic necrosis during reamed intramedullary nail fixation of femoral shaft fractures. Currently, this system is used in extended applications including accessing large volume of autologous bone graft, as alternative for iliac crest harvesting. Antegrade femoral bone graft harvesting using the Reamer-Irrigator-Aspirator system is considered the standard technique.
