Interprosthetic femoral fracture is a rare and challenging fragility fracture issue. Due to aging of the population, the incidence of this type of fracture is gradually and constantly increasing. There is no complete and specific interprosthetic femoral fracture classification system that indicates treatment and prognosis in the literature. The aim of the(More)
PURPOSE The present study aims to evaluate if the bicipital groove can be used as a parameter for ideal plate positioning in proximal humeral fixation applying locking compression plate. METHOD The authors questioned whether the bicipital groove can be used as a parameter for ideal plate positioning applying locking compression plate for proximal humeral(More)
The authors report the cases of two young patients who had suffered a sporting accident with posterior traumatic dislocation of sternoclavicular joint. In one of the patients closed reduction was accomplished by keeping the limb in a sling. The second patient, after reduction was done, presented recurrence of the dislocation, thus requiring surgical(More)
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 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 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)
Rupture of the patellar tendon is a well-known injury in the orthopaedic literature. However, it is unusual and rarely reported in adolescent children. On the one hand, in the immature skeleton, the most frequent lesion above the kneecap is the sleeve fracture. On the other hand, in the distal region, avulsion of the tibial tuberosity is more common.(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 compare the duration of exposure to radiation among patients with fractures of the distal third of the tibia treated with an intramedullary nail or with a bridge plate. METHODS Intramedullary nails were used for 33 fractures, and bridge plates were used for 41 fractures. In the nail group, according to the AO classification, 14 patients had(More)
