Introduction: This article was undertaken to explore the potential of AI in enhancing the diagnostic accuracy and efficiency in identifying hip fractures using X-ray radiographs. In the study, we trained three distinct deep learning models, and we utilized majority voting to evaluate their outcomes, aiming to yield the most reliable and precise dia...

Dear Editor The most common comorbid diseases in patients undergoing lower extremity amputation for nontrau- matic reasons are diabetes mellitus (DM), peripheral arterial disease, and chronic renal failure (CRF). The primary cause of peripheral arterial disease is a circulatory disturbance of the lower extremity, whereas, in DM patients, it is peri...

Objective: The aim of this study was to compare clinical and histopathological effects of oral versus intraarticular corticosteroid application in a rat model of frozen shoulder. Methods: In this study, eighty adult Sprague-Dawley rats were used. The animals were divided into 5 equal groups. The frozen shoulder model was created by immobilizing...

Objective: The present study aims to define the characteristics of the necrotizing fasciitis (NF) cases followed at our hospital and to compare our results with the literature.

1 959 yılında Arthur Samuel [1] yapay zekayı "prog-ramlamaya gerek olmadan bilgisayara öğrenme yeteneği verebilme kabiliyeti" olarak tanımladı. Geçen 60 yıl içinde makine öğrenmesi ile başlayan süreç derin öğrenme, insan beynini taklit eden nöral öğrenme ve evrişimsel sinir ağları ile ivme kazan-dı. Özellikle grafik işlemcilerdeki gelişmeler ve Moo...

The use C-arm fluoroscopy is indispensable in the practice of orthopedics and traumatology, particularly in trauma surgery. However, the ideal way to protect both health- care personnel and patient from ionizing radiation from image acquisition is to minimize the unnecessary radia- tion exposure. The universal laser pointer has a 12-inch tube, whic...

Femoral neck fractures are a serious health problem, especially in the elderly population. Misdiagnosis leads to improper treatment and adversely affects the quality of life of the patients. On the other hand, when looking from the perspective of orthopedic surgeons, their workload increases during the pandemic, and the rates of correct diagnosis m...

Abstract Aim: The present study aims to investigate the the long-term effect of metallic orthopedic instruments that were broken and not removed during surgery on the health status of patients. Material and Methods: Radiographs of 12,601 patients (5765 females and 6836 males; mean age: 48.9 years; range: 0-105) who underwent orthopedic surgery in o...

Recently, the rate of the production and renewal of information makes it almost impossible to be updated. It is quite difficult to process and interpret large amounts of data by human beings. Unlimited memory capacities, learning abilities, artificial intelligence (AI) applications, and robotic surgery techniques cause orthopedic surgeons to be con...

Objectives: This study aims to detect frontal pelvic radiograph femoral neck fracture using deep learning techniques. Patients and methods: This retrospective study was conducted between January 2013 and January 2018. A total of 234 frontal pelvic X-ray images collected from 65 patients (32 males, 33 females; mean age 74.9 years; range, 33 to 89...

Objectives: This study aims to introduce a new low-cost universal laser aiming device (LAD) that can be used in existing C-arm fluoroscopy devices, independent of brand and model, and to determine whether this new universal LAD improves technician accuracy in locating the desired region at the midpoint of the fluoroscopic image. Materials and met...

Background and aims Diabetic patients undergoing below the knee amputation often represent with severe concomitant conditions. Intraoperative anaesthetic management may also have an impact on overall morbidity and morbidity. However, there still exists controversial information on the superiority of any anaesthetic technique over the other. The aim...

Amaç: Çalışmamızın amacı erken dönem en yüksek hastane mortalitesine sahip ortopedik cerrahi prosedürü ve mortalite üzerine etki eden faktörleri saptamaktır.Gereç ve Yöntem: 1998-2016 yılları arasında ortopedik cerrahi geçirmiş 19.727 hasta çalışmaya dahil edildi. Bu hastalardan ameliyat sonrası dönemde ilk 30 gün içinde hastanede ölen 370 hastanın...

The aim of this study is to explore the effect of teriparatide on fracture healing in rats with chronic renal disease. 16 of the 32 Spruge Dawley rats underwent nephrectomy. Osteotomy was performed on the right femurs all of the rats 3 weeks after surgery. Eight rats of teriparatide were administered for 4 weeks forming a healthy and chronic kidney...

Aims: To determine if patients who undergo below-knee amputation (BKA) for intractable wounds caused by diabetes complications receive adequate treatment before surgery. Materials and methods: The study included a total of 528 patients who underwent transtibial amputation for diabetic foot. All patients were assessed on the basis of duration of...

Purpose: The aim of this study was to determine the factors affecting the mortality and the orthopedic surgical procedure with the highest hospital mortality. Material and Methods: 19,727 patients who had undergone orthopedic surgery between 1998-2016 were included in the study. Patients who underwent outpatient surgery were not included in the st...

Objective: The purpose of this study was to compare the single-bundle (SB) and double-bundle (DB) surgical techniques for anterior cruciate ligament (ACL) reconstruction with regard to tunnel widening, isokinetic muscle strength, and clinical outcomes over an 8-year follow-up period. Methods: This study included 31 patients with ACL injury who u...

irçok kemik kırığında olduğu gibi gençlerde yüksek enerjili, yaşlılarda düşük enerjili travmaya bağlı gelişen proksimal humerus kırıkları en sık görülen ilk 4 kırık içerisinde yer alır. 1 Ortalama yaşam süresinin artışıyla beraber insi-dansı yıllar içerinde artış göstermiştir. 2 1934 yılında Codman ile başlayan proksi-mal humerus kırıkları sınıflam...

Introduction: Untreatable foot problems in diabetics may require lower extremity amputation, which has a high level of patient mortality. This high mortality rate is worse than most malignancies. The present study aimed to identify parameters that can be used to estimate survival in DM patients undergoing below-knee amputations for diabetic foot p...

Thirty-one patients who suffered anterior cruciate ligament (ACL) injury and underwent ACL reconstruction (16 single-bundle, 15 double-bundle) with ENDOBUTTON between November 2007 and March 2008 were included in the study. Isokinetic and concentric strength measurements of the quadriceps and hamstring muscles at the 6th month and 8th year were mad...

Glucocorticoids (GC), often used in the treatment of diseases caused by autoimmune mechanisms, are the most common nontraumatic causative factor of femoral head avascular necrosis (FHAN). FHAN is, in turn, the most common cause leading to orthopedic surgery in patients using GCs. As GCs suppress the immune system, patients experience increased susc...
