Objective: This study aimed to compare the clinical and comprehensive radiological outcomes of 3 types of endoscopic decompression surgery: unilateral biportal endoscopic lumbar decompression (UBELD), microendoscopic laminotomy (MEL), and percutaneous endoscopic lumbar decompression (PELD). Methods: Patients with single-level lumbar spinal stenosis...

Background Surgical treatment is usually required for malignant foot and ankle tumors. In this study, we sought to review factors in treatment that may be associated with morbidity and mortality. Methods All malignant foot and ankle tumors at our institution between April 1988 and April 2018 were retrospectively reviewed. The surgical modalities u...

Objectives: This study aims to investigate the factors that may be associated with surgical site infection and mortality in pelvic resection surgeries. Patients and methods: A total of 68 patients (40 males, 28 females; mean age: 43±16.2 years; range, 11 to 70 years) who underwent internal or external hemipelvectomy between January 2010 and January...

Objectives: It is aimed to investigate the effect of tourniquet and tranexamic acid (TXA) on the amount of perioperative bleeding in patients undergoing total knee arthroplasty. Methods: One hundred and ninety-three patients included in the study. The patients included in the study were divided into 4 groups. Group 1 (n = 78) was determined as the...

Purpose Most of the internet users search online on YouTube for their health problems and the treatments. The purpose of this study is to evaluate the quality and the reliability of the videos on YouTube for Carpal tunnel syndrome (CTS). Methods The search was made by typing the keywords “Carpal tunnel syndrome” and/or “CTS” into the YouTube search...

Purpose: Our purpose is to clarify the optimal timing of surgery after transarterial embolization (TAE) for renal cell carcinoma (RCC) bone metastases. Methods: This retrospective study included 41 patients with RCC bone metastases embolized between 2013 and 2019. Different-sized particulate and/or liquid embolic agents were used for TAE. Emboli...

Purpose The aim of this study was to compare the injury patterns of orthopaedic trauma patients in the paediatric age group who presented to our hospital during and after lifting the curfew due to the pandemic, with the patients of the same age group who presented to our institution during the same time period last year. Methods Patients, aged 0 y...

Objective: This study aimed to investigate whether various curfew practices affect trauma prevalence, epidemiological differences among the population admitted to hospital because of trauma, and treatment practices used after trauma. Methods: Patients who suffered from fractures or soft-tissue trauma between March 21, 2020, and June 1, 2020, (grou...

Objectives:A failed intertrochanteric fixation often leads to functional disability and pain. The most commonly observed complication is “cut-out”, which frequently requires hip arthroplasty in the subsequent period. In this study, we aimed to compare the results of total hip arthroplasty (THA) and hemiarthroplasty (HA) after cut-out complication o...

Objectives: We aim was to evaluate the quality and reliability of the information on knee arthroplasty available on YouTube in Turkish. Methods: A systematic search was conducted using the term “diz protezi” (knee prosthesis) on 1 June 2020.Videos were filtered based on their degree of relevance alone. Videos that were not in Turkish, not on knee p...

Background Steroid injection is a common method in the treatment of unicameral bone cysts (UBC). In this study, the relationship between the clinical results and inflammatory molecules’ levels in the cyst fluid was evaluated after three repeated steroid injections in UBC subjects.Methods Twenty-one patients diagnosed with UBC were treated with meth...

Objective: The aim of this study was to develop a new radiological classification system for postoperative spinal epidural hematoma (SEH) using magnetic resonance imaging (MRI) and to determine the correlation of this classification system with clinical and radiological outcomes. Methods: This prospective study included a total of 245 consecutiv...

Objectives: Avascular necrosis (AVN) of the femoral head is a type of osteonecrosis caused by impaired blood flow to the proximal femur. Femoral head collapse and coxarthrosis are seen in more than 30% of the patients with AVN of femur, and the only definitive treatment in this group is hip arthroplasty (THA). The post-operative results of this dis...

Study design: Prospective single center cohort study. Objective: The present study aims to investigate the causes of failure of L5/S1 foraminal stenosis, and it is hypothesized that the newly defined "L5 coronal root angle(CRA)" may be a parameter in the removal of ventral pathologies. Summary of background data: Lumbar foraminal stenosis is a...

Background: Lumbar disk herniation can be successfully treated by lumbar endoscopic spinal procedures. However, one of the most important disadvantages of the endoscopic methods used is radiation exposure. There are multiple endoscopic spinal procedures and this study aims to compare unilateral biportal endoscopic diskectomy (UBED), percutaneous e...

Objective: The aim of this biomechanical experimental study was to evaluate the resistance of each posterior ligamentous complex structure of the thoracic and lumbar spine to compression forces and to measure the shifting load to the intervertebral disc when each PLC structure was interrupted. Method: The study was conducted on 4 groups for thor...

Objective: To prospectively evaluate with magnetic resonance imaging (MRI), the relationship between the distance from the incision of the drain output location and postoperative spinal epidural hematoma (SEH) in patients performed with microendoscopic decompressive laminotomy (MEDL) for lumbar spinal stenosis. Methods: Between January 2016 and Jun...

Malignant triton tumor (MTT) is a rare variant of malignant peripheral nerve sheath tumor (MPNST) made up of both malignant schwannoma cells and malignant rhabdomyoblasts. A 26-years-old male patient was admitted with an asymptomatic gluteal mass. Magnetic resonance imaging showed heterogeneous soft tissue mass and he underwent open biopsy. Maligna...

The car-tyre friction injury has differences from other injuries. The components of injury which are burn, crushing, shearing, and degloving occur. Many treatment options can be performed for coverage of wound which are Vacuum Assisted Closure system (V.A.C), skin grafting, free flaps, local flaps and cross leg flap.

Objective: In this study, we sought to review the clinical and histopathological features and the chemotherapy regimens in osteogenic sarcoma in patients over 40 years of age, and we aimed at identifying the possible prognostic factors in this particular group of patients. Methods: We reviewed 287 patients with osteosarcoma treated between the year...

Objective: The purpose of this study is to give the information on the outcome, management and survivability of patients with low extremity liposarcoma. Methods: This study is a retrospective study. All the patients were seen and managed between 1986 and 2010. Their records were retrieved and analyzed for this study. Fiftynine cases were identified...
