WEDGE FRAGMENT VARIATIONS OF TIBIAL SHAFT FRACTURES WITH INTRAMEDULLARY NAILING.

Introduction: Tibial shaft fracture is the most common long-bone fracture, and the standard treatment is intramedullary (IM) nail fixation. Regardless of the development of this technique pseudoarthrosis remains prevalent.

Objectives: Evaluate the correlation between wedge fragment size and displacement, displacement of the main fragments of the 42B2 type, and pseudoarthrosis incidence.

RADIOLOGICAL RESULTS OF SEVERE SCFE TREATMENT AT IOT-FMUSP FROM 2012 TO 2018.

Objective: To assess the complications in patients with severe slipped capital femoral epiphysis treated with the Dunn or modified Dunn procedure from 2012 to 2018 at the Institute of Orthopedics and Traumatology, Medical School, Universidade de São Paulo.

Methods: Analysis of medical records, preoperative and postoperative radiographs with at least one year of radiographic follow-up of patients with severe slipped capital femoral epiphysis.

Results: We reviewed the complications in 19 operated cases from 2012 to 2018, out of which 36.

THE MISSING LINK IN THE HISTORY OF THE LOCKED INTRAMEDULLARY NAIL.

Femoral Shaft intramedullary nails were first described by the Aztecs in 16th century, but the modern use of intramedullary nails as the gold standard treatment for femoral shaft fractures began with Gerald Kuntcher in 1939. From the first Kuntcher's study in 1939, to the creation of interlocking nail, a long and some minor developments were described around the world. However, a major development is missing: the first nail to have a rotational and vertical stability locking system was described by Flavio Godoy Moreira, but was never published on an indexed journal for the correct historical reference.

Bioactive glass S53P4 to fill-up large cavitary bone defect after acute and chronic osteomyelitis treated with antibiotic-loaded cement beads: A prospective case series with a minimum 2-year follow-up.

Introduction: Bioactive glass S53P4 (BAG-S53P4) has been used in the treatment of osteomyelitis with excellent results. The aim of this study was to evaluate the clinical and radiographic results of patients treated with use of antibiotic-loaded cement beads, followed by bone defects filling using bioglass.

Methods: We treated a prospective series of patients presenting with acute or chronic osteomyelitis of a long bone of the upper or lower limb.

Factors associated with one year mortality in ill patients with proximal femoral fractures treated non operatively.

Introduction: Non-operative treatment is an exceptional indication for the treatment of proximal femur fracture. The aim of the study was to analyze the mortality rate in one year and associated factors in severely ill patients submitted to non-operative treatment.

Methods: It was included 28 patients treated from August 2014 to September 2019.

Intramedullary Steinmann pin nailing of the ulna: an option for the damage control orthopedics treatment of forearm fractures in open injuries in polytraumatized patients - A description of the technique and presentation of a case series.

Introduction: Forearm shaft fracture is common in young adult patients and associated with soft tissue and organ injuries. In open fractures in polytrauma patients, damage control orthopaedics (DCO) is well indicated. The aim of this study is to describe intramedullary Steinmann pin fixation of the ulna as a DCO procedure for the forearm and present a case series.

A novel translation system for circular external fixation to correct translational bony deformities.

Translational deformities are common complications of conservatively managed bone fractures and some surgically managed fractures with unstable patterns. Realigning the bones can be difficult when soft tissue, scars and calluses form. These deformities can be easily corrected with hexapodalic-based external fixators, but these fixators are not widely available in developing countries.

A RETROSPECTIVE CASE-SERIES ON THE USE OF S53P4 BIOACTIVE GLASS FOR THE ADJUNCTIVE TREATMENT OF SEPTIC DIAPHYSEAL NON-UNION.

Objective: Non-union and persistence of infection at a fracture site for long periods are always described as a challenge to orthopedists, especially in cases of severe compound fractures with comminution and segmental bone loss. This is a case series of septic non-unions, using S53P4 bioactive glass for adjunctive treatment, using internal syntheses or external fixators. The objective is to retrospectively evaluate the results of the use of S53P4 bioglass for the adjunctive treatment of septic non-unions.

COMPARATIVE STUDY BETWEEN OSTEOSYNTHESIS IN CONVENTIONAL AND BIOABSORBABLE IMPLANTS IN ANKLE FRACTURES.

To compare the functional results of ankle fractures treated with metallic and absorbable plates. Twenty patients were randomized into two groups (metallic and absorbable implant groups) and followed prospectively. In the immediate postoperative period, patients were immobilized with plaster casts for one week, which was replaced by a removable cast for another four weeks.
