The impact of curfews on emergency departments and orthopedic traumas.

BACKGROUND: The aim of our study was to investigate the impact of curfews imposed due to the COVID-19 pandemic on emergency department visits, orthopedic trauma frequencies, and types of trauma. METHODS: In this single-center, retrospective cohort study, a total of 16,242 patients, including 3,020 trauma patients, were admitted to level 1 trauma center emergency department between April-June 2020 and 2021 (curfew group) and between April-June 2018 and 2019 (control group). Patients were separated according to emergency department triage categories and trauma mechanisms, and the changes in the days of curfew were analyzed. RESULTS: With the curfews, there was a 54% decrease in emergency room admissions. This decrease was seen especially in yellow and green area patients, whereas there was no significant decrease in red area patients with the highest urgency. When the effect of curfews on orthopedic traumas was analyzed, a 20% decrease was observed in trauma cases. In particular, there was a significant decrease in traffic accidents in and out of the vehicle, assault, and sports injuries, whereas there was no significant decrease in falls from the same level, motor accidents, and occupational accidents. CONCLUSION: The impact of curfews on the density of emergency departments and trauma patients will guide the health management policies to be followed in future curfews to be implemented for different reasons. In the light of this information, more effective resource management and better quality health service planning will be ensured.

The management of orthopedic trauma surgery during the COVID-19 pandemic in Turkey.

COVID-19 has now alarmed the whole world, putting many countries' health systems in trouble. We aimed to evaluate the affect of the new treatment strategy that shortens hospital stay in orthopedic trauma patients in pandemic.Trauma patients who underwent surgical treatment between March 15th-May 1st 2019 and 2020 were examined about time interval from admission to surgery, period from surgery to discharge and total hospital stay time. This cohort was compared to a retrospective cohort of patients admitted for the same reasons in the same period of the previous year. During COVID pandemia, 51 trauma patients operated with the mean period from admission to operation 1.45 days, faster than the previous year's same period (3.76 days). From operation day to discharge time was 1.6 days in pandemic period and 4.3 days last year. The total hospitalization period (3,05 days) was significantly shorter in pandemic than the same period of the last year (8,06 days). (p<0.05). No complications and mortality were observed in any of our patients with faster trauma treatment strategy in pandemic. The operation of orthopedic trauma patients requiring surgery during a pandemic in a shorter time than normal time will not increase the complication and mortality, but will also help to use the bed more effectively by reducing the hospital stay.

NO SIGNIFICANT EFFECT OF 3D MODELLING ON SURGICAL PLANNING IN SPINAL DEFORMITIES.

Objective: To evaluate the effect of 3d printed models on surgical pre-operative planning of complex spinal deformities. Methods: In our study, five orthopedic surgeons made surgical planning of 5 patients with severe spinal deformity in three conditions: X-ray with computer tomography (X-ray-CT), 3D-computed tomography (3dCT), and 3d printed spine models. Operation plans were examined according to the level and number of instrumentations, osteotomy level, and time required for decision-making. Results: X-ray-CT, 3dCT, and 3d modeling methods were compared, and no statistically significant difference was observed in the number of screws and osteotomy score to be used in operation. The time required for decision ranking is 3d Model, 3d CT, and Xray-CT. Conclusions: 3d printed models do not influence the operative plan significantly; however, it reduces surgical planning time at pre-op duration, and those models gave some opportunities to practice with implants on a patient's 3d spine model. Level of Evidence III; Diagnostic Studies - Investigating a Diagnostic Test .

Objetivo: Avaliar o efeito de modelos 3D impressos no planejamento pré-operatório cirúrgico de deformidades complexas da coluna vertebral. Métodos: Em nosso estudo, 5 cirurgiões ortopédicos fizeram o planejamento cirúrgico de 5 pacientes com deformidade espinhal grave em três condições: raio-X com tomografia computadorizada (raio X-CT), tomografia computadorizada com reconstrução 3D (3dCT) e modelo de coluna vertebral impressa (modelo 3d). Os planos de operação foram examinados de acordo com o nível e número de instrumentos, nível de osteotomia e tempo necessário para a tomada de decisão. Resultados: Foram comparados os métodos de modelagem de raio X-CT, 3dCT e modelo 3d e nenhuma diferença estatisticamente significativa foi observada no número de parafusos e escore de osteotomia a serem utilizados na operação. O ranking do tempo necessário para a tomada de decisão foi de modelo 3d, 3d CT e raio X-CT. Conclusões: Os modelos impressos em 3d não influenciam significativamente o plano operatório, porém reduzem o tempo de planejamento cirúrgico no pré-operatório e esses modelos deram algumas oportunidades de praticar com implantes no modelo de coluna 3d do paciente.

Assessing the knee flexion range of motion after total knee arthroplasty: Technology versus senses.

INTRODUCTION: Following total knee arthroplasty surgery, attention should be paid to post-operative knee range of motion to achieve daily activities. Goniometer assessment is widely used to assess the range of motion in the post-operative period. This study aimed to determine the inter-rater ability of a smartphone application and visual estimation of the knee joint after total knee arthroplasty among different professions that commonly work together and compare whether any method is superior to another. METHOD: Range of motion measurements was performed by four clinicians as two physiotherapists and two orthopedic fellows. They utilized the Goniometer Reports application for smartphones, universal goniometer, and visual estimation to measure angles of knees which was operated. A two-way mixed model of intra-class correlation coefficient (ICC) with a 95% confidence level was used to assess inter-rater reliability. RESULTS: Thirteen patients (11 female) and 20 knees (10 right) were assessed. The ICCs were found excellent both for between methods and between raters. CONCLUSION: Our results show that technology seems a more accurate way to determine the knee range of motion after knee arthroplasty compared to senses. However, in lack of technological resources or time, or to avoid possible infection, visual estimation also could provide useful information.

Combination of anatomical locking plate and retrograde intramedullary nail in distal femoral fractures: comparison of mechanical stability.

OBJECTIVES: This study aims is to investigate mechanical properties of intramedullary (IM) nailing and anatomical locking plate in a bone model based on the hypothesis that their combined usage increases safety of fixation stabilization. MATERIALS AND METHODS: Twenty-one left distal femoral fracture models were used in the study. Bones were divided into three equal groups. Group 1 specimens were fixed laterally by distal femoral anatomical locking plate. Group 2 specimens were fixed with retrograde distal femoral IM nail. Group 3 specimens were fixed with both distal femoral anatomical locking plate and retrograde distal femoral IM nail. In mechanical tests, alterations in axial loading, torsion angles, and load to failure values were measured and compared between groups. RESULTS: Compared to group 1, group 2 was relatively more resistant in axial load tests (p=0.225), and significantly more resistant in load to failure tests (p=0.048). Group 1 was relatively more resistant in torsional load tests (p=0.949) compared to group 2. Group 3 was significantly more resistant than group 1 in axial (p=0.001), torsional (p=0.012) load tests and load to failure tests (p=0.008). Group 3 was significantly more resistant compared to group 2 in axial (p=0.003), torsional (p=0.008) load tests, and relatively more resistant (p=0.059) in load to failure tests. CONCLUSION: Thanks to its high mechanical strength and early mobilization capability, distal femoral anatomical locking plate and IM nail combination might be a choice of treatment in complicated osteoporotic or distal femoral fractures from high-energy trauma in young adults.

Total knee arthroplasty in ochronosis: a case report and critical review of the literature.

Alkaptonuria is an autosomal recessive disorder caused by the deficiency of homogentisate 1.2 dioxygenase activity. The clinical presentation shows an ochronotic pigment which is deposited in all connective tissues, including in cartilage, particularly. The knee is the most common site of peripheral abnormality. There is currently no definitive cure for alkaptonuric ochronosis. In this article, we present a 69-year-old male case who underwent bilateral cemented total knee arthroplasty simultaneously. Our results during two-year follow-up were satisfactory. A critical review of the literature revealed no uniformity in reporting such cases.
