Objective: The impact of preoperative consultations on mortality and morbidity rates, and their association with delays and hospital stays for surgery, remains a topic of discussion. This study aims to elucidate the necessity of consultations for those undergoing femoral neck fracture surgery, examining their influence on delays, hospital durations, and their correlation with mortality rates.

Methods: The study examined data from 320 emergency department patients with femoral neck fractures undergoing hip arthroplasty surgery at our hospital between 2011 and 2021, using digital medical records.

Purpose: Several clinical and experimental studies have revealed that L-Arginine, which has antioxidant properties, accelerates tissue healing. This study examined the in vivo effects of oral L - Arginine supplementation on tendon regeneration in Wistar rats.

Method: For each weighting of an average of 250-300 g, 24 Wistar rats were separated into three equal groups.

Objectives: This study aims to investigate whether the medial cortical ratio (MCR) is associated with fixation failure in patients undergoing plate-screw fixation due to proximal humeral fracture.

Patients And Methods: Between May 2011 and October 2020, a total of 93 patients (25 males, 68 females; mean age: 74.2±5.

Background: Supracondylar humerus fractures (SCHFs) are the most common types of elbow fractures in children. Closed reduction percutaneous pinning (CRPP) is the primary surgical treatment of SCHFs. In cases that cannot be managed with closed reduction, treatment with open reduction and internal fixation (ORIF) is necessary.

Objective: To demonstrate the effect of medical ozone therapy on the development of epidural fibrosis.

Methods: A total of 25 Sprague-Dawley male rats were randomly divided into 3 groups: a control group (L3-L4 laminectomy only), a systemic ozone therapy (SOT) group (L3-L4 laminectomy only + intraperitoneal 15 mL [30 μg/mL] ozone), and a local ozone therapy (LOT) group (L3-L4 laminectomy only + subcutaneous 15 mL [30 μg/mL] ozone). Ozone therapy was administered 4 times on a 3-day interval during the wound-healing process, with the first dose immediately administered after surgery.

Background: The purpose of this study is to compare biomechanical properties of suprapectineal (SP) plate fixation, in-frapectineal (IP) plate fixation, and both SP and IP plate fixation in anterior column posterior hemitransverse (ACPHT) fractures of the acetabulum using posterior and anterior column screws.

Methods: In 21 hard plastic left hemipelvis models, ACPHT fractures of the acetabulum were created, and in three different fixa-tion groups, the methods were compared: Group 1: SP plating using a 3.5 mm reconstruction plate and cortical screw fixation, Group 2: İnfrapectineal plating using 3.

Tuberculosis (TB) infection is a common health problem in low socioeconomic populations in developing countries. Osteoarticular TB is a disease that rarely occurs outside the vertebral column and is often diagnosed late or misdiagnosed, particularly in non-weight bearing joints. A 51-year-old female patient with Behçet's disease presented with shoulder TB following rotator cuff repair surgery, leading to joint resection as a result of recurrent infections with no reproduction in culture samples due to delayed diagnosis.

Objectives: This study aims to evaluate wound healing effects of in vitro radial extracorporeal shock wave (rESW) application on mouse fibroblasts and whether the cytotoxic effect of extracorporeal shock wave (ESW) was due to a possible genotoxic effect.

Patients And Methods: After creating an in vitro wound healing model in L929 mouse fibroblast culture, fibroblasts were stimulated with a frequency of 3 Hz, and 100, 250, 500, 1,000 and 1,500 pulses shock waves were applied. Energy flux densities ranging from 0.

Aim: To compare biomechanical results between different polymethylmethacrylate (PMMA) augmentation methods on failed lumbar pedicle screw models of animal vertebrae.

Material And Methods: Thirty lumbar vertebrae were harvested from six calves, and their bone mineral density was measured. 60 Polyaxial pedicle screws were inserted to all vertebrae.

Objectives: The aim of this study was to investigate the relationship between MMP13 rs3819089, ADAM12 rs3740199 and rs1871054, and ADAMTS14 rs4747096 genotypes in patients with radiologically diagnosed knee osteoarthritis (OA).

Patients And Methods: A total of 300 patients (68 males, 232 females; mean age: 61.6 years; range, 25 to 89 years) who were admitted to the orthopedics and traumatology clinic and diagnosed with knee OA according to the 2000 American College of Rheumatology (ACR) criteria between October 2018 and March 2019 were prospectively analyzed.

Objectives: This study aims to investigate the effect of radial extracorporeal shock wave therapy (rESWT) treatment in the prevention of epidural fibrosis after laminectomy in rats.

Materials And Methods: Eighteen 16-month-old male Sprague-Dawley rats weighing 300 g were used in this experimental study between November 2019 and February 2020. The rats were randomly divided into two groups as the control group (L3-L4 total laminectomy without any treatment) and the study group (L3-L4 total laminectomy plus rESWT).

Aims And Objectives: The purpose of this study was to compare the potential effects of pedunculated and free synovial grafts in the repair of full-thickness articular cartilage defects on an animal model with histological and immunohistochemical analysis.

Materials And Methods: A comparative study in an animal model was performed with 24 rabbits, divided into two groups. Full-thickness cartilage defects were created bilaterally on the knees of all rabbits.

Objectives: This study aims to investigate the clinical and radiological outcomes of core decompression surgery performed with multiple drilling in solid organ transplantation patients with osteonecrosis of femoral head (ONFH) and evaluate the effectiveness of this procedure in regard to duration of corticosteroid use and stage of osteonecrosis.

Patients And Methods: A total of 22 solid organ transplantation (kidney, liver or heart) patients (14 males, 8 females; mean age 43.3 years; range, 23 to 67 years) who were scheduled to undergo core decompression surgery with multiple drilling for ONFH were evaluated.
