QUANTITATIVE AND QUALITATIVE INVESTIGATION OF THREE-DIMENSIONAL GAIT ANALYSIS IN PATIENTS WITH CERVICAL MYELOPATHY.

Objective: This study aims to describe a kinematic gait assessment protocol and identify its main alterations in individuals with cervical spondylotic myelopathy (CSM) compared to healthy patients.

Methods: In total, 14 patients diagnosed with CSM were enrolled and submitted to a three-dimensional gait analysis. The movement of patients was captured with infrared emission cameras that identified tracking markers placed on the lower limbs.

Assessment of inter- and intraobserver agreement for META score in distinguishing osteoporotic from multiple myeloma vertebral fractures.

Purpose: To conduct an independent assessment of inter- and intraobserver agreement for the META score as a tool for differentiating osteoporotic vertebral fractures and multiple myeloma vertebral fractures.

Methods: This is a retrospective observational study. The magnetic resonance imaging analysis was made by two independent spinal surgeons.

Efficacy of Dynamic Magnetic Resonance Imaging in the Diagnosis of Degenerative Cervical Myelopathy: Systematic Review Protocol.

Cervical degenerative myelopathy (CDM) is a cervical spine condition resulting in clinical manifestations of spinal cord compression related to the chronic, non-traumatic, and progressive narrowing of the cervical spinal canal. Conventional magnetic resonance imaging (MRI) is the gold standard test to diagnose and assess the severity of CDM. However, the patient is in a neutral and static position during the MRI scan, which may devalue the dynamic factors of CDM, underestimating the risk of spinal cord injury related to cervical spine flexion and extension movements.

Methodology for Preoperative Planning of Bone Deformities Using Three-dimensional Modeling Software.

Rapid prototyping technology, known as three-dimensional (3D) printing, and its use in the medical field are advancing. Studies on severe bone deformity treatment with 3D printing showed benefits in postoperative outcomes thanks to this technology. Even so, preoperative planning guidance for surgeons is lacking.

EARLY COMPLICATIONS OF SURGICAL TREATMENT OF CERVICAL SPONDYLOTIC MYELOPATHY.

Objective: To evaluate the early postoperative complications associated with the surgical approach of the cervical spine of patients with cervical spondylotic myelopathy (CSM), comparing the anterior surgical, the posterior surgical, and the combined approaches.

Methods: This is a retrospective study based on a database with 169 patients. Demographic data, such as gender and age, and surgical data, such as surgical approach, number of segments with arthrodesis, surgical time, and complications, were evaluated.

Child Fractures: Are We Getting More Surgical?

Historically, surgeries on the immature skeleton were reserved for open or articular fractures. In recent years, the improvement in the quality and safety of anesthesia, new imaging equipment, implants designed especially for pediatric fractures, associated with the possibility of shorter hospitalization time and rapid return to social life has demonstrated a new tendency to evaluate and treat fractures in children. The purpose of this update article is to answer the following questions: (1) Are we really turning more surgical in addressing fractures in children? (2) If this is true, is this surgical conduct based on scientific evidence? In fact, in recent decades, the medical literature demonstrates articles that support better evolution of fractures in children with surgical treatment.

Impacts of the Delayed Surgical Correction of Adolescent Idiopathic Scoliosis and its Repercussions for the Brazilian Unified Health System: Systematic Review Protocol.

Surgical correction is an effective treatment for adolescent idiopathic scoliosis (AIS) with deformities over 45°. In the Brazilian Unified Health System (SUS, Sistema Único de Saúde), if the surgical procedure is indicated, the patients are placed on a waiting list and wait until the treatment can be performed. An extended waiting period can be harmful due to worsening symptoms and increased treatment costs.

The impacts of waiting for surgical correction of Adolescent Idiopathic Scoliosis and its repercussions for publicly funded health systems: systematic review.

Purpose: To investigate, through a systematic review, the impact of the waiting time for Adolescent Idiopathic Scoliosis (AIS) surgical correction from the point of view of deformity evolution, treatment cost, and quality of life.

Methods: PubMed, Embase, LILACS, SciELO, Scopus, Web of Science, LIVIVO, and Cochrane Library databases were searched by two researchers to select the articles. The eligibility criteria were: Patients diagnosed with AIS with indication for surgical correction and submitted to waiting lists until treatment.

Systematization of Steps for Printing 3D Models of Orthopedic Deformities.

As in many areas of knowledge, rapid prototyping technology or additive manufacturing, popularly known as three-dimensional (3D) printing, has been gaining ground in medicine in recent years, with different applications. Numerous are the benefits of this science in orthopedic surgery, by allowing the conversion of imaging tests into 3D models. Therefore, the aim of the present study is to describe a practical step-by-step for the printing of parts from patient imaging.

REPRODUCIBILITY OF S2-ALAR ILIAC SCREW MORPHOMETRIC ANALYSIS.

Objective: To evaluate the reproducibility of a S2-alar iliac (S2AI) screw parameters measurement method by inter and intraobserver reliability.

Methods: Cross-sectional study, considering computed tomography exams. Morphometric analysis was performed by multiplanar reconstructions.

Description of the Sacropelvic Parameters Measurement Method for S2-alar iliac Screw Insertion.

 Description of the sacropelvic parameters measurement method for S2-alar iliac (S2AI) screw insertion.  Descriptive study of the method for measuring sacropelvic parameters for the insertion of the S2AI screw using computed tomography (CT). The data evaluated in multiplanar reconstructions were the parameters of the screw trajectory, including length, diameter and angles of the trajectory in the axial and sagittal planes.

DOUBLE FEMORAL OSTEOTOMY FOR THE TREATMENT OF SEVERE SEQUELAE OF THE IMMATURE HIP.

Objective: To evaluate the results of double femoral osteotomy for the treatment of severe sequelae of the hip.

Methods: Immature patients with anatomical loss of the hip were treated with pelvic support osteotomy in the distal femur to correct lower limb shortening, they were evaluated clinically and radiographically.

Results: Eleven cases (eleven hips) were assessed with verage follow-up of three years.

ASSESSMENT OF THE POSTERIOR APPROACH FOR SURGICAL TREATMENT OF SPINAL METASTATIC BREAST CANCER.

Objective: To assess the clinical and radiological aspects of patients with spinal metastatic breast cancer who underwent surgical treatment by posterior approach.

Methods: This is a retrospective and descriptive study. Clinical assessment included the patient's sex, age, surgical treatment employed and complications.
