OBJECTIVE we prospectively evaluated clinical and radiographic outcomes in patients with displaced combined transverse-posterior wall acetabular fractures managed at our Institution over a period of seven years by posterolateral single approach, direct posterior wall and posterior column reduction and plating, and indirect reduction of anterior column(More)
OBJECTIVE To compare the existence of agreement between measurements of anteversion of the femoral neck and the degrees of osteoarthritis and abnormality of the neck-shaft angle in patients with unilateral idiopathic hip osteoarthritis, among three evaluators. METHODS Forty-two patients with unilateral hip osteoarthritis were evaluated by means of simple(More)
OBJECTIVE To analyze the tip-apex distance (TAD), cervicodiaphyseal angle and Garden angle in stable and unstable extracapsular fractures of the femur treated with a plate and sliding screw. METHOD Hip radiographs in anteroposterior (AP) and lateral view on 117 patients were evaluated. The fractures were classified as stable or unstable, using the AO(More)
OBJECTIVE To define the anthropometric profile of the knee in a Brazilian population with gonarthrosis using intraoperative measurements; and to evaluate the compatibility of three implants available for total knee arthroplasty. METHODS Morphometric data were collected prospectively from 117 subjects with gonarthrosis. Six dimensions in the distal femur(More)
OBJECTIVE To define the distal femur rotation pattern in a Brazilian population, correlating such pattern with the one suggested by the arthroplasty instruments, and analyzing the variability of each anatomic parameter. MATERIALS AND METHODS A series of 101 magnetic resonance imaging studies were evaluated in the period between April and June 2012. The(More)
OBJECTIVE To evaluate the relationship between patients' body mass index (BMI) and the degree of radiographic severity of knee osteoarthrosis. METHOD 117 patients with gonarthrosis were evaluated prospectively. The patients' BMI was calculated and their knee arthrosis was classified in accordance with the modified Ahlbäck criteria. Kruskal-Wallis analysis(More)
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(More)
Bilateral stress fracture of femoral neck in healthy young patients is an extremely rare entity, whose diagnostic and treatment represent a major challenge. Patients with history of hip pain, even non-athletes or military recruits, should be analyzed to achieve an early diagnosis and prevent possible complications from the surgical treatment.

OBJECTIVE To analyze knowledge of the anatomic location of the piriform fossa using a questionnaire with anatomic figures. MATERIALS AND METHODS Participants taking AO Trauma Brasil courses were requested to complete a questionnaire containing a photograph of the superior surface and a photograph of the lateral surface of the femur and answer a question(More)
BACKGROUND Open pelvic fractures are rare but usually associated with a high incidence of complications and increased mortality rates. The aim of this study was to retrospectively evaluate all consecutive open pelvic fractures in patients treated at a single Level-1 Trauma Center during a 10-year interval. PATIENTS AND METHODS In a 10-year interval, 30(More)
