Analysis of the Accuracy of CAM-type Deformity Resection on a Low-cost Arthroscopic Simulator in a Training Scenario.

To evaluate surgeons' performance in resecting CAM-type deformities using a realistic arthroscopic surgery simulator. An arthroscopic simulator was created using low-cost materials with the help of a GTMax Core A1 3D printer and the programs Invesalius and Meshmixer 2017, which were used to develop femoral head parts in ABS material, with the presence of a CAM-type deformity, to mimic a femoroacetabular impact situation. After the operations were performed by 16 surgeons, the femurs were compared to a previous model with deformity and another without, using Cloudcompare, and parameters such as the volumetric difference between the operated femurs, with and without deformity, the minimum and maximum distance between them, the percentage of the deformity resected, the estimated time for total resection of the deformity, as well as a qualitative analysis based on the images and graphs provided by the program representing the areas of the parts resected, were evaluated at the end.

Epidemiology and costs of surgical treatment of developmental dysplasia of hip in the Brazilian Public Health System in a decade.

Objective: To describe and analyze the epidemiology and costs of surgical treatment of hip dysplasia in the Brazilian Public Health System.

Methods: An ecological analytical study that evaluated a time series and the geographic distribution of surgical treatment of hip dysplasia in Brazil. Frequencies of cases, number of cases and associated factors were analyzed.

Protocol of BRICS: Brazilian multicentric pragmatic randomised trial of surgical interventions for displaced diaphyseal clavicle fracture study: MIPO versus ORIF for the treatment of displaced midshaft clavicle fractures.

Introduction: Fractures of the diaphysis of the clavicle are common; however, treatment guidelines for this condition are lacking. Surgery is associated with a lower risk of non-union and better functional outcomes but a higher risk of complications. Open reduction and internal fixation with plates and screws are the most commonly performed techniques, but they are associated with paraesthesia in the areas of incisions, extensive surgical exposure and high rates of implant removal.

Conservative Approach to Type III Ulnar Club Hand: Case Report.

Ulnar club hand is a rare condition of the upper limbs, for which treatment depends on the degree of morphological and functional impairment, correlating with the radiographic classification of Dobyns, Wood, and Bayne. The aim of the present study is to report a case of a 6-year-old male patient, followed up for type III ulnar club hand (total ulnar dysplasia). Despite the initial difficulty of manipulating objects and performing everyday tasks, conservative physical therapy treatment provided strength gain and development of functional skills for daily life.

Three-Dimensional Digital Surgical Planning and Rapid Prototyped Surgical Guides in Bernese Periacetabular Osteotomy.

Bernese periacetabular osteotomy (PAO) developed by Ganz is currently the treatment of choice for skeletally mature symptomatic patients with developmental dysplasia of the hip (DDH) without osteoarthritis. However, the steep learning curve and considerable number of severe complications lead surgeons to seek for alternatives to promote greater reproducibility and safety of this procedure. This is a report of a DDH case surgically treated with the aid of a digital three-dimensional (3D) planning and rapidly prototyped sterile ABS plastic osteotomy guide, developed in Brazil.

Comparative Study of Function and Quality of Life in Patients with Fracture of the Tibial Plateau Operated with Locked or Conventional Plates.

Objective: To compare clinical, functional, and quality of life outcomes between patients with tibial plateau fractures operated with locked or conventional plates, and to compare the costs of these implants.

Methods: This was a comparative cross-sectional study of a consecutive series of patients with tibial plateau fractures treated surgically from August 2015 to June 2016. Patients < 18 years old, those unable to answer the questionnaires or to attend the outpatient reassessment, polytrauma patients, those with associated injuries on the ipsilateral limb, and patients who had not undergone treatment with bone plates were excluded.

Mixed-type femoroacetabular impingement associated with subspine impingement: recognizing the trifocal femoropelvic impingement.

To describe the arthroscopic surgical technique for subspine impingement (SSI) of the anterior inferior iliac spine (AIIS) associated with mixed type femoroacetabular impingement (FAI), through two standard arthroscopic portals (anterolateral and distal mid-anterior) in two patients with trifocal impingement. The authors report the cases of two young male patients, aged 32 and 36 years old, with trifocal femoropelvic impingement (TFPI). The technique consists of segmental capsulectomy, arthroscopic dissection of the AIIS, partial release of the direct head of the rectus femoris, resection of the AIIS projection with a burr and with fluoroscopic aid, correction of the pincer deformity, repair of the labrum with bioabsorbable anchors, and femoral osteoplasty.

Primary and secondary osteoporotic fractures prophylaxis: evaluation of a prospective cohort.

Objective: To measure the prevalence of primary drug prevention of fractures due to osteoporosis in patients admitted to a tertiary teaching hospital, in a medium-sized city, admitted with osteoporotic fractures. Moreover, to identify the incidence of prescribing secondary prophylaxis after the first fracture event. At the same time, the prevalence of risk factors for such fractures as described in the literature was measured.

DEVELOPMENTAL DYSPLASIA OF THE HIP: DO THE RESPONSIBLE FOR SCREENING KNOW WHAT TO DO?

Objective: To evaluate the knowledge on developmental dysplasia of the hip (DDH) by professionals involved in its diagnosis.

Methods: This is a cross-sectional study using questionnaires to assess the knowledge about DDH. Orthopedic surgeons and pediatricians, residents and medical students from a tertiary teaching hospital were included in the study.

Parental awareness and perception for correct use of child restraint systems and airbags in Brazil.

Objective: The objective of this study was to obtain information about the current knowledge and habits of parents who transport children in cars in Brazil.

Methods: A cross-sectional survey was conducted using specifically designed self-report questionnaires to parents of children attending a private pediatric office in a town in southwest Brazil. Data were collected regarding children's age, gender, height, and weight and possession of an automobile child restraint system (CRS), its type, frequency and adequacy of use, and reasons for not possessing or not using the devices.

Surgical Treatment of a Case of Ledderhose's Disease: A Safe Plantar Approach to Subtotal Fasciectomy.

Plantar fibromatosis, Ledderhose's disease, or Morbus Ledderhose is an uncommon benign nodular hyperplasia of the plantar aponeurosis. The aim of this paper was to report the case of a 47-year-old male patient who had concomitant Dupuytren's disease and failed all conservative measures. He was treated surgically with prompt and complete relief of symptoms postoperatively, and he has had no recurrence at the 2-year follow-up.

Superficial Acral Fibromyxoma of the Thumb: A Case Report.

The authors report a case of superficial acral fibromyxioma (SAF) in a 74-year-old male who presented with a painless mass in a periungual dorsoradial region of the right thumb. It is a rare benign neoplasm, which was recently described, that arouse on the skin and subcutaneous tissue of the hands and feet, especially in the proximity to the ungual region of male adults. Surgical treatment was performed with the excision in blocks of the margins of the lesion and fragmentation of the nail and nail matrix, according to the literature recommendation.

Do complications in hip arthroscopy change with experience?

Purpose: The aim of this study was to evaluate the type and incidence of complications during the development of hip arthroscopic techniques.

Methods: A retrospective series of 194 files of patients treated with hip arthroscopy in a tertiary hospital from December 1999 to March 2008 was reviewed for complications. The incidence of complications was recorded consecutively for each group of 30 patients and in intervals of 2 years.
