DIAGNOSTIC COMPETENCE IN BONE TUMORS: INFLUENCE OF ONCO-ORTHOPEDIC TRAINING.

Unlabelled: Understanding the nature of musculoskeletal tumors is crucial for appropriate management and to secure a favorable prognosis. Orthopedists' ability to identify these pathologies early and accurately is paramount. There is a requirement to raise awareness within the orthopedic community regarding the necessity of referrals to orthopedic oncology specialists, as delays in initiating proper treatment can compromise patient prognosis.

Methods: Retrospective observational case series study to evaluate the results of elbow cancer undergoing clinical and/or surgical treatment with the first visit from 1990 to 2020. The dependent variables were benign bone tumor, malignant bone tumor, benign soft tissue tumor, malignant soft tissue tumor.

EPIDEMIOLOGICAL PROFILE AND EVOLUTION OF ANKLE MUSCULOSKELETAL TUMORS.

Objective: Characterizing ankle tumors, presenting the epidemiological profile of these lesions.

Methods: Retrospective observational case series study to evaluate the results of clinical and/or surgical treatments of patients with ankle tumors whose first visit occurred from 1990 to 2020. The dependent variables were: benign bone tumor, malignant bone tumor, benign soft tissue tumor, malignant soft tissue tumor, and infection.

JUXTACORTICAL OSTEOSARCOMA: CLINICAL EVOLUTION AND DEDIFFERENTIATION RELATED FACTORS.

Objective: Evaluate risk factors related to clinical evolution and dedifferentiation of parosteal (juxtacortical) osteosarcoma to high-grade osteosarcoma.

Methods: Retrospective cohort study performed over a period of 25 years, using data from medical records of patients diagnosed with parosteal osteosarcoma. The data were submitted to statistical analysis by Fisher's exact test and Student's t-test.

Risk Factors Related to Poor Outcomes in the Treatment of Non-conventional Periprosthetic Infection.

 To identify the main risk factors related to poor outcomes after the treatment for periprosthetic infection.  Medical records from 109 patients who underwent non-conventional endoprosthesis surgeries (primary and revision procedures) from January 1, 2007, to December 31, 2018, were retrospectively evaluated. In total, 15 patients diagnosed with periprosthetic infection were eligible to participate in the study.

Biopsy Path Contamination in Primary Bone Sarcomas.

Objective: To determine the incidence of contamination of the biopsy pathway in patients with primary bone sarcomas, as well as the clinical characteristics that influenced this outcome.

Materials And Methods: The anatomopathological reports of the patients who were treated by the Orthopedic Oncology Sector of the Orthopedic and Traumatology Department of this institution were retrospectively evaluated.

Results: Of the 148 patients included for evaluation in the present study, only 1 presented contamination by neoplastic cells in his biopsy pathway.

Is PET-CT an accurate method for the differential diagnosis between chondroma and chondrosarcoma?

The differential diagnosis between chondroma and intraosseous chondrosarcoma is based on imaging and clinical exams, but only a biopsy can confirm diagnosis. The aim of this study was to evaluate the value of PET-CT in differentially diagnosing chondroma and chondrosarcoma. From October 2009 to May 2015, 36 patients with cartilaginous bone lesions in the extremities, 12 (33.

Analysis of epidemiology, lifestyle, and psychosocial factors in patients with back pain admitted to an orthopedic emergency unit.

Objective: To correlate epidemiological data, lifestyle, and psychosocial factors as predictors for clinical manifestation of back pain in patients treated at the orthopedic emergency unit of a Brazilian tertiary care hospital, and to evaluate their interest in participating in a hypothetical program for physical rehabilitation.

Methods: This is an observational cross-sectional study. We evaluated 210 patients from the emergency department of a tertiary hospital with a major complaint of back pain.

Advanced units: quality measures in urgency and emergency care.

Objective: To evaluate, through care indicators, the quality of services rendered to patients considered urgency and emergency cases at an advanced emergency care unit.

Methods: We analyzed data from managerial reports of 64,891 medical visits performed in the Emergency Care Unit of the Ibirapuera Unit at Care during the period from June 1st, 2012 through May 31st, 2013. The proposed indicators for the assessment of care were rate of death in the emergency care unit; average length of stay of patients in the unit; rate of unplanned return visits; admission rate for patients screened as level 1 according to the Emergency Severity Index; rate of non-finalized medical consultations; rate of complaints; and door-to-electrocardiogram time.

Postural assessment of patients with non-conventional knee endoprosthesis.

Objective: To investigate the correlation between the sagittal and frontal alignment and possible postural asymmetries found in patients submitted to total knee stent placement for osteosarcoma.

Methods: TWENTY TWO INDIVIDUALS WERE DIVIDED INTO TWO GROUPS ACCORDING TO TUMOR LOCATION: femur group (13 patients) and tibia group (nine patients), who were evaluated through postural analysis software (SAPO).

Results: No statistically significant difference was found between groups, supporting previous result showing that both groups present the same postural asymmetries.

Epidemiology of total hip and knee replacement: a cross-sectional study.

Objective: To describe the epidemiologic characteristics and adverse events of patients submitted to total hip and total knee replacement.

Methods: A cross-sectional study retrospectively assessing medical chart data of all total hip and total knee replacements performed at a private hospital, between January 2007 and December 2010 Patients submitted to total hip and total knee replacement, with consent of surgeons were included. Incomplete records and/or missing data of the hospital database were excluded.
