Intramedullary nail versus bridge plate in open tibial fractures - randomized clinical trial.

Introduction: Open tibial shaft fractures present a challenge to the orthopedic surgeon, because they are common, have a high rate of complications and still have a controversial treatment. As a result of the high incidence of these fractures, the need of a definitive treatment and the unavailability of the intramedullary nail or a well-trained team, we developed this study to compare the effectiveness of the bridge-plating (BP) with the unreamed intramedullary nail (UIMN) in the treatment of open tibial shaft fractures.

Materials And Methods: Eighty patients were included in a prospective, consecutive and random way and then randomized in two groups of treatment: unreamed intramedullary nail and bridge-plating.

Quick-DASH as a main early outcome of humeral shaft fractures: A Latin American multicenter prospective study.

Purpose: The main objective of this study was to evaluate the Quick-Disabilities of the Arm, Shoulder and Hand Score (DASH) score as the main early (90 days) outcome in a prospective multicenter observational Latin American study on isolated humeral shaft fractures.

Methods: From December 2015 to April 2017, in six Latin American countries, patients 18 years or older with a closed, isolated nonpathological 12A, 12B, or 12C AO/OTA (Arbeitsgemeinschaft für Osteosynthesefragen/Orthopaedic Trauma Association) fractures were included. The 90 (±10)-day Quick-DASH score was used to compare the results of the different treatments.

Minimally invasive posteromedial percutaneous plate osteosynthesis for diaphyseal tibial fractures: technique description.

Purpose: The aim of this study was to evaluate the feasibility of performing minimally-invasive plate osteosynthesis (MIPO) in tibial fractures using two posteromedial incisions, and to measure the distance between the plate and neurovascular structures.

Materials And Methods: We performed nine dissections of specimens that were submitted to tibial MIPO with two posteromedial incisions. One locking compression plate (LCP) of 14 to 16 holes was inserted into the submuscular tunnel in a retrograde manner.

Risk of injury to vascular-nerve bundle after calcaneal fracture: comparison among three techniques.

Objective: To ascertain whether the number of screws or pins placed in the calcaneus might increase the risk of injury when three different techniques for treating calcaneal fractures.

Method: 126 radiographs of patients who suffered displaced calcaneal fractures were retrospectively analyzed. Three surgical techniques were analyzed on an interobserver basis: 31 radiographs of patients treated using plates that were not specific for the calcaneus, 48 using specific plates and 47 using an external fixator.

Treatment of pelvic fractures - a national survey.

Introduction: This survey was conducted during the 38(th) Brazilian Congress of Orthopaedics and Traumatology to identify the opinion of Brazilian orthopaedic surgeons on the standard treatment of pelvic fractures.

Materials And Methods: Participants were randomly selected and invited to voluntarily answer a questionnaire of 10 multiple choice questions addressing the main aspects of the treatment of pelvic fractures: classification, fixation methods in unstable patients, optimal surgical timing in stable patients, and fixation methods in different types of anterior and posterior pelvic injuries.

Results/conclusion: Three hundred and fifty-two questionnaires were completed, and the following main observations were made: most orthopaedists prefer to use an external fixator in the iliac crest for the emergency stabilisation of pelvic injuries in haemodynamically unstable patients (79.

Profile of trauma victims of motorcycle accidents treated at hospital São Paulo.

Objective: To evaluate retrospectively, through analysis of medical records, the epidemiological aspects of patients traumatized by motorcycle accidents treated at the orthopedics ward, Hospital São Paulo, Brazil.

Methods: It is a retrospective observational study. The analysis of patients' medical records comprised the period from January 2008 to December 2009.

Minimal invasive ostheosintesis for treatment of diaphiseal transverse humeral shaft fractures.

Objective: To evaluate patients with transverse fractures of the shaft of the humerus treated with indirect reduction and internal fixation with plate and screws through minimally invasive technique.

Methods: Inclusion criteria were adult patients with transverse diaphyseal fractures of the humerus closed, isolated or not occurring within 15 days of the initial trauma. Exclusion criteria were patients with compound fractures.

Recommendations for avoiding knee pain after intramedullary nailing of tibial shaft fractures.

Background: The objective of this study is to analyze the proximal tibiofibular joint in patients with knee pain after treatment of tibial shaft fractures with locked intramedullary nail.

Findings: The proximal tibiofibular joint was analyzed in 30 patients, who reported knee pain after tibial nailing, and standard radiograph and computed tomography were performed to examine the proximal third of the tibia. Twenty patients (68.

CROSS-SECTIONAL STUDY ON DIFFERENT ENTRY POINTS FOR ANTEROGRADE FEMORAL INTRAMEDULLARY OSTEOSYNTHESIS.

Objective: To analyze the degree of knowledge among professionals who treat fractures using the recommended technique, with regard to correlating the nail with the entry point that is considered appropriate.

Methods: A questionnaire that presented five types of nail and simulated a transverse diaphyseal fracture of the femur was developed.

Results: Responses regarding the entry points corresponding to choosing the type of nail were obtained from 370 orthopedists who were participating in the 41(st) Brazilian Congress of Orthopedics and Traumatology.

SUBCLAVIAN VEIN THROMBOSIS FOLLOWING FRACTURE OF THE CLAVICLE: CASE REPORT.

Deep vein thrombosis in the upper limbs is uncommon in the orthopedic literature. We report on a case of subclavian vein thrombosis that occurred during conservative treatment of a fracture in the middle third of the clavicle. This is difficult to diagnose and requires a high degree of suspicion.

CORRELATION BETWEEN TIME UNTIL SURGICAL TREATMENT AND MORTALITY AMONG ELDERLY PATIENTS WITH FRACTURES AT THE PROXIMAL END OF THE FEMUR.

Objective: The primary aim of this study was to analyze the possible association between delay in receiving surgical treatment and mortality among elderly patients with fractures at the proximal end of the femur.

Methods: 269 patients with fractures at the proximal end of the femur (femur neck and intertrochanteric fractures) who were treated surgically at Hospital São Paulo, UNIFESP, São Paulo, between January 2003 and December 2007, were studied. The following attributes were analyzed and compared with the literature relating to this subject: sex, age, type of fracture, classification of the fracture, affected side, synthesis used, trauma mechanism, length of hospitalization, waiting time for surgery, associated comorbidities, hemogram on admission, type of anesthesia, need for blood transfusion, day of the week and season of the year of the fracture.

CLINICAL AND ANATOMICAL COMPARISON OF THE FIBULAR NERVE IN GERDY's SAFE ZONE.

Objective: To clinically and anatomically compare the limits of the fibular nerve in Gerdy's safe zone in cadavers.

Methods: Fifty anatomical knee specimens were clinically measured (before dissection) to determine the distances and angles between Gerdy's tubercle and the posterior region of the fibula (cm); the angle between the line corresponding to the posterior region of the fibula and the tibial crest (degrees); and the angle between Gerdy's tubercle and the tibial crest (degrees). After dissection of the anatomical specimens, the knees were measured again, to determine the distances and angles between Gerdy's tubercle and the fibular nerve (cm); the angle between the fibular nerve, in the posterior region of the fibula, and the tibial crest (degrees); and the angle between Gerdy's tubercle and the tibial crest (degrees).

OSTEOSYNTHESIS WITH INTRAMEDULLARY NAILS IN CHILDREN.

The authors present a comprehensive review of the literature emphasizing the use of flexible intramedullary nails in the treatment of fractures in children, focusing the treatment of femoral shaft and forearm fractures and emphasizing the importance of the non-surgical approach. Children's age and weight threshold are not well defined for the use of the method. The removal of implants is a controversial matter in the literature, with a trend towards keeping the implants.
