Introduction: Low- to high-energy impact trauma may cause from small fissures up to extended bone losses, which can be classified as closed or opened injuries (when they are visible at a naked eye).

Objective: The aim of this study was to investigate the feasibility of clinical diagnosis of bone trauma through medical infrared thermography, in a hospital emergency room.

Methods: Forty-five patients with suspected diagnosis of bone fracture were evaluated by means of medical infrared images, and the data correlated with the gold standard radiographic images, in the anteroposterior, lateral, and oblique views, at the orthopedic emergency department. The control group consisted of thermal images of the contralateral reference limb of the volunteers themselves. Data were acquired with a medical grade infrared camera in the regions of interest (ROIs) of leg, hand, forearm, clavicle, foot, and ankle.

Results: In all patients evaluated with a diagnosis of bone fracture, the mean temperature of the affected limb showed a positive difference greater than 0.9 °C (towards the contralateral), indicating the exact location of the bone trauma according, while the areas diagnosed with reduced blood supply, showed a mean temperature with a negative variation.

Conclusion: Clinical evaluation using infrared imaging indicates a high applicability potential as a tool to support quick diagnosis of bone fractures in patients with acute orthopedic trauma in an emergency medical setting. The thermal results showed important physiological data related to vascularization of the bone fracture and areas adjacent to the trauma well correlated to radiographic examinations.

Non-contact infrared sensors are widely used as a diagnostic tool for elevated body temperature during initial screening for coronaviruses. The aim of this study was to investigate the thermal differences at three anatomical points: temple, forehead, and wrist, in the initial screening for temperature indicative of febrile and non-febrile states in skin pigmentation variations in Black, Half-Black and Caucasian skins, correlated with height and weight variables. Temperatures were obtained by means of an infrared thermometer in 289 volunteers with mean age of 18.30 ± 0.76, in a controlled environment according to Singapore Standard, SS582 part 1 and 2, normative standard IEC 80601-2-59, with standard technical protocols established by the International Organization for Standardization, ISO / TR 13154. The data were processed in MATLAB® R2021a, and data normality verified by Kolmogorov-Smirnov test, non-parametric data paired between temple / forehead / wrist were compared using the Wilcoxon signed-rank test. The results show different median temperatures in these anatomical regions, 37.2°C at the temple, 36.8°C at the forehead and 36.4°C at the wrist. As the temple region presents a temperature higher than the other investigated regions and, therefore, close to the core temperature, it should be considered for the initial screening of SARS-CoV-2 when using non-contact infrared thermometers. Furthermore, no significant changes were found due to variation in skin tone, height, or weight.

TREATMENT OF TRIPLANE FRACTURE ANKLE FRACTURES ASSOCIATED WITH IPSILATERAL TIBIAL FRACTURES USING A NOVEL APPROACH.

Acta Ortop Bras 2021 Nov-Dec;29(6):323-326

Hospital do Trabalhador, Curitiba, PR, Brazil.

Objective: The aim of this study is to purpose a novel approach to the concomitant triplanar and tibial shaft fracture.

Methods: Retrospective study between 2001 and 2019. We collected the patients' general information, clinical and radiographic data, and complications after the following three-step treatment: (1) fixation of the Salter-Harris II fracture of the triplane fracture, (2) fixation of the Salter-Harris II/IV fracture with cannulated screws, and (3) fixation of the tibial fracture with flexible titanium nails.

Results: The study included seven patients (six males) with a mean age of 14 years and a mean follow-up of 6.4 years (minimum two years). Five triplane fractures had two fragments and two had three fragments. Five fractures were classified as Salter-Harris II and two as Salter-Harris IV. Three tibial fractures were long oblique, three were spiral, and one had a third fragment. Six fractures affected the middle third and one affected the distal third of the tibia. All triplane and tibial fractures consolidated without significant displacement. No physeal damage was identified.

Conclusions: This study described the association of tibial fractures with triplane ankle fractures managed by our proposed treatment, which proved to be effective for this fracture association.

Evaluation of Tibia Bone Healing by Infrared Thermography: A Case Study.

J Multidiscip Healthc 2021 13;14:3161-3175. Epub 2021 Nov 13.

Universidade Tecnológica Federal do Paraná, Curitiba, Paraná, Brasil.

Background: Thermal imaging has been used as a clinical follow-up technique in several medical specialties.

Purpose: The aim of this study was to investigate the feasibility of using medical thermography in the diagnosis and follow-up assessment of a severe orthopedic trauma that requires the use of an external circular fixator.

Patients And Methods: Twenty clinical follow-ups of thermal imaging correlated with X-ray images were performed in a male volunteer, diagnosed with bone nonunion, during 11 months of treatment, in the hospital trauma and reconstruction department. Data were acquired in the regions of interest of the proximal tibia, diaphysis and distal, with a Flir T530 medical grade infrared camera from Flir Systems, and the data processed by the Matlab 2019 custom made software.

Results: Statistical analysis was performed by Wilcoxon signed-rank test. The results showed a median temperature of 22.2°C, and thus some periods of interruption in the healing process between the third and twentieth clinical follow-up, and a significant increase of the temperature to 34.6°C synchronous with a diagnosis of bone infection by the eleventh clinical follow-up. The thermal images acquired during the 20 clinical follow-ups allow a correlation with the data from the X-ray exams and also with the contralateral limb of the evaluated patient, showing thermal alterations greater than 0.3°C, which are significant of physiological abnormality.

Conclusion: The thermography exam can be a useful tool for applying on the follow-up of patients after trauma or bone fracture. The results showed important physiological data related to the vascularization necessary for bone repairing, being therefore a good indicator of the healing process. In addition, as infrared thermography does not use ionizing radiation, it can be used countlessly, in complement to the traditional X-ray exams that focus on anatomical data analysis.

Finite Element Analysis of a Controlled Dynamization Device for External Circular Fixation.

Rev Bras Ortop (Sao Paulo) 2021 Feb 19;56(1):36-41. Epub 2021 Feb 19.

Programa de Pós-Graduação em Odontologia, Faculdade de Ciências da Vida, Pontifícia Universidade Católica do Paraná (PUCPR), Curitiba, Paraná, Brazil.

 To virtually prototype a device for external circular fixation of long bone fractures with controlled dynamization made of two different materials and predict their mechanical behavior by using the finite element analysis (FEA) method.  A software was used for 3D modeling two metal parts closely attached by a sliding dovetail joint and a high-density silicone damper. Distinctive FEAs were simulated by considering two different materials (stainless steel or titanium), modes (locked or dynamized) and loading conditions (static/point or dynamic/0.5 sec) with uniform 150 kg axial load on top of the device.  The finite elements (FEs) model presented 81,872 nodes and 45,922 elements. Considering stainless steel, the maximum stress peak (140.98 MPa) was reached with the device locked under static loading, while the greatest displacement (2.415 × 10 mm) was observed with the device locked and under dynamic loading. Regarding titanium, the device presented the maximum stress peak (141.45 MPa) under static loading and with the device locked, while the greatest displacement (3.975 × 10 mm) was found with the device locked and under dynamic loading.  The prototyped device played the role of stress support with acceptable deformation in both locked and dynamized modes and may be fabricated with both stainless steel and titanium.

CHRONIC MONTEGGIA FRACTURE-DISLOCATION IN CHILDREN SURGICAL STRATEGY AND RESULTS.

Acta Ortop Bras 2019 Sep-Oct;27(5):244-247

Hospital do Trabalhador, Curitiba, PR, Brazil.

Objective: To report surgical techniques and results in the treatment of chronic Monteggia fracture-dislocation in children.

Methods: Six pediatric patients who had undergone a procedure involving the following 6 crucial surgical steps were retrospectively evaluated: 1- extended lateral approach, 2- fibrotic removal, 3-proximal ulnar osteotomy, 4- reduction of the radial head and transcapitellar temporary fixation, 5- ulnar fixation with a straight plate shaped according to the deformity generated by temporary fixation, and 6- transcapitellar Kirschner wire removal.

Results: Four patients were women, and four showed the right-sided compromise. The mean age of patients was 8 years, and the minimum follow-up period was 12 months. The mean time from the onset of fracture to treatment was 6 months. Six patients underwent complete flexo/extension, and one patient had a complete prono-supination. In four patients, we observed loss of pronation (by 10° in two, 15° in one, and 20° in one), and one patient had a 15° decrease in supination. We did not observe any redislocation of the radial head in the follow-up evaluation. No complications were observed; the only complaint was salience of the ulnar plate.

Conclusions: Our results demonstrated an effective option for the treatment of chronic Monteggia fracture-dislocation in children, even with a small study sample, following the presented technical and surgical strategies.

Surgical treatment of femoroacetabular impingement using controlled hip dislocation after occurrence of slipped capital femoral epiphysis.

Rev Bras Ortop 2016 Jul-Aug;51(4):418-23. Epub 2016 Jul 4.

Universidade Federal do Paraná, Hospital do Trabalhador, Curitiba, PR, Brazil.

Objective: To present our experience and preliminary results from using controlled hip dislocation to treat cam-like femoroacetabular impingement, in teenagers and young adults with sequelae of slipped capital femoral epiphysis.

Methods: This was a retrospective analysis on 15 patients who were treated in a tertiary-level hospital between 2011 and 2013. The following data were collected for analysis from these patients' files: demographic data, surgical procedure reports, joint mobility evaluations, patients' perceptions regarding clinical improvement and whether they would choose to undergo the operation again, previous hip surgery and complications. The exclusion criteria were: follow-up shorter than six months, the presence of any other hip disease, osteotomy of the proximal femur performed at the same time as the osteochondroplasty and incomplete medical files with regard to the information needed for the present study.

Results: Fifteen patients (17 hips) who underwent osteochondroplasty to treat femoroacetabular impingement were evaluated. Nine of them were women, the mean age was 18 years old and the minimum follow-up was two years. Two patients underwent osteochondroplasty bilaterally; eight patients were operated on the left side and five on the right side. In 14 cases, the greater trochanter was lowered (relative lengthening of the neck) in association with the osteochondroplasty. For 13 patients, their previous surgery consisted of fixation of an occurrence of slipped capital femoral epiphysis; for six patients (eight hips), flexor osteotomy was performed previously; and for one patient, hip arthroscopy was performed previously. Fourteen patients presented improvement of mobility and hip pain relief, in comparison with before the operation, and they said that they would undergo the operation again. Two complications were observed: one of loosening of the fixation of the greater trochanter and one of heterotopic ossification.

Conclusion: The preliminary results from this study suggest that osteochondroplasty through controlled surgical hip dislocation is a good option for treating femoroacetabular impingement. Through this method, the patients reported achieving improvement of joint mobility and hip pain, with few complications.

Analysis on the risk of contralateral proximal femoral epiphyseal slippage using the modified Oxford score.

Rev Bras Ortop 2015 Sep-Oct;50(5):562-6. Epub 2015 Sep 9.

Hospital Universitário Cajuru, Pontifícia Universidade Católica do Paraná (PUC-PR), Curitiba, PR, Brazil.

Objective: To determine the application of the modified Oxford score among patients with proximal femoral epiphyseal slippage (PFES) as an aid to indicating prophylactic surgical treatment on the contralateral hip.

Methods: Retrospective analysis on the medical files of patients attended at the institution where the authors work. From these, patients attended between 2008 and 2011 who presented unilateral PFES and were followed up for a minimum of two years were selected. Patients were excluded if they presented endocrine disease, metabolic disease, Down syndrome or radiographs that were inadequate for determining the modified Oxford score. The initial radiographs received scores ranging from 16 to 26. Statistical analysis was used to determine whether the scoring was predictive of future development of contralateral slippage.

Results: Among the 15 patients with unilateral PFES that were selected, five (33.3%) evolved with contralateral slippage. The patients were divided into two groups. Four patients were considered to present risk and three of them developed contralateral slippage. In the group that was considered not to present risk, there were 11 patients and two of these evolved with contralateral slippage. Thus, there was a tendency for the patients in the group that developed the disease to differ from the group that did not develop it, in relation to the risk classification.

Conclusion: Although application of the modified Oxford score was not statistically significant in our sample, we noted a tendency toward contralateral slippage among hips with low scores.

UNSTABLE FEMORAL FRACTURES TREATED WITH TITANIUM ELASTIC INTRAMEDULLARY NAILS, IN CHILDREN.

Rev Bras Ortop 2012 Sep-Oct;47(5):575-80. Epub 2015 Nov 4.

Third-year Resident Physician in the Orthopedics and Traumatology Clinic, Cajuru University Hospital, Pontifical Catholic University of Paraná (PUC-PR), Curitiba, PR, Brazil.

Objective: To evaluate the indications, epidemiology, associated lesions, complications and prognosis among children with unstable femoral diaphysis fractures who were treated with titanium elastic intramedullary nails.

Method: This was a retrospective analysis on 24 patients aged 5-12 years with unstable femoral diaphysis fractures who underwent surgical treatment with elastic titanium intramedullary nails at the Cajuru University Hospital, Curitiba-PR, between April 2002 and March 2008, with a minimum follow-up of 36 months. The epidemiological data, angular deviations, leg shortening and bone consolidation were evaluated.

Results: The medical files of 113 cases operated between April 2002 and March 2008 were reassessed. From these, 24 cases of unstable femoral diaphysis fractures treated with elastic titanium intramedullary nails with retrograde insertion were included in the study. There were two bilateral fractures and two exposed fractures. Seven patients were female and 17 were male, and the mean age was 8.3 years. The following were presented at the end of the study: shortening, varus or valgus displacement, final retrocurvatum or antecurvatum of zero, and absence of delayed consolidation or pseudarthrosis.

Conclusions: The elastic titanium intramedullary nails were easily placed and removed. We believe that using elastic titanium intramedullary nails is a good option for fixation of unstable femoral fractures in children.
