Objective: To assess the clinical and radiographic characteristics of hip joint deformities in children with congenital Zika syndrome (CZS), and the evolution of hip joint deformities in affected infants for the first 3 years of life.
Study Design: This prospective observational study evaluated orthopedic clinical examinations performed every 3 months to assess hip flexion and extension, lateral and medial rotation, and abduction and adduction, as well as lower limb muscle length and tone. The biannual radiograph comprised anteroposterior panoramic pelvic radiographs with the lower limbs in extension.
Objective: This research sought to carry out a comparative study observing the clinical and radiographic analysis of primary prostheses of the type TC3 Depuy Johnson with or without a stem during a short-term follow-up.
Methods: The sample was divided into three groups: Group 1 (with stem), Group 2 (without stem) and Group 3 (mixed). Patients were evaluated to assess whether the implants were loosening and a clinical analysis was performed.
Successful biomaterials for bone tissue therapy must present different biocompatible properties, such as the ability to stimulate the migration and proliferation of osteogenic cells on the implantable surface, to increase attachment and avoid the risks of implant movement after surgery. The present work investigates the applicability of a three-dimensional (3D) model of bone cells (osteospheres) in the evaluation of osteoconductive properties of different implant surfaces. Three different titanium surface treatments were tested: machined (MA), sandblasting and acid etching (BE), and Hydroxyapatite coating by plasma spray (PSHA).

Methods: Eight fresh-frozen human specimens ranging from 38 to 82 years old were used. Specimens were positioned supine with the shoulder in 70° abduction and the forearm in full supination.
Objectives: The purpose of this study was to evaluate the accuracy and reliability of pre-operative templating in predicting the size of femoral and tibial components and the effect of coronal deformity on templating accuracy.
Methods: This was a retrospective study of 39 pre-operative templates prepared by three different surgeons with different levels of training. The accuracy and reliability measures were evaluated by alpha and kappa coefficients of agreement.

Purpose: To analyze the early outcomes of viscosupplementation in patients with severe knee osteoarthritis.
Method: A randomized, double-blind clinical trial of 143 knees divided into three groups: Group 1 - intra-articular injection of triamcinolone; Group 2 - hylan GF20; and Group 3 - triamcinolone + hylan GF20. Outcomes were evaluated using Lysholm and KSS scores before treatment and after one, three and six months.

Objective: To compare intraoperative measurements of the knee with those obtained by magnetic resonance imaging, in order to validate the latter method for use in anthropometric studies.
Materials And Methods: We studied 20 knees in 20 patients with osteoarthritis, all of whom underwent total arthroplasty between August and December of 2013. We took six measurements in the distal femur and two in the proximal tibia.
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 asking which of four numbered points corresponded to the piriform fossa.
Results: Just 4.

Background: Several so-called casting indices are available for objective evaluation of plaster cast quality. The present study sought to investigate four of these indices (gap index, padding index, Canterbury index, and three-point index) as compared to a reference standard (cast index) for evaluation of plaster cast quality after closed reduction of pediatric displaced distal forearm fractures.
Methods: Forty-three radiographs from patients with displaced distal forearm fractures requiring manipulation were reviewed.
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 treatment.

Surgeons also decide how to follow up with patients who have lead fragments retained in their body. Current literature recommends to remove only intra-articular fragments without the need for a follow-up for patients with the metal retained.

It is difficult to diagnose the disease due to its insidious onset and non-specific clinical presentation. A high degree of suspicion and appropriate imaging studies are necessary for its early diagnosis and treatment.

This work evaluates the suitability of biphasic calcium phosphate (BCP) granules (β-TCP/HA 70:30) as potential carriers for cell-guided bone therapy. The BCP granules were obtained by synthesis in the presence of wax, thermal treatment, crushing and sieving and characterized by scanning electron microscopy (SEM), X-ray diffraction and Fourier transform infrared spectroscopy. The cytocompatibility of the BCP granules was confirmed by a multiparametric cytotoxicity assay.
