Article Synopsis
- The study investigates the impact of patient positioning during surgery on the rotational alignment of femoral trochanteric fractures treated with intramedullary nails.
- 84 patients were divided into two groups based on their intraoperative position: supine on a fracture table and lateral decubitus, with femoral malrotation angles measured through CT scans.
- Results showed no significant relationship between patient position and malrotation, but the lateral position reduced fluoroscopy images and preparation times, making it a practical option for surgery.
Article Synopsis
- The study looks at a type of foot surgery called arthrodesis for patients who had problems after their first joint surgery.
- It involved 27 patients, mostly women, who were followed for at least 6 months after their surgery to see how well they recovered.
- The results show that after surgery, patients had less pain and improved ability to walk, and the angles of their foot bones got better too! *
Article Synopsis
- The study investigates the effectiveness of various biocompatible materials (PLA, PLA/HA, PEEK) compared to titanium plates in treating midshaft clavicle fractures, focusing on their biomechanical stability.
- Finite element analysis revealed that titanium experienced significantly higher maximum von Mises stresses than the biocompatible materials, indicating a higher risk of implant failure with titanium.
- Although PLA and PLA/HA showed inadequate fixation, PEEK demonstrated greater stability than titanium, suggesting it may be a better alternative for managing these fractures.
Background And Objectives: We aimed to determine the effects of vanillic acid (VA) on fracture healing radiologically, histologically, immunohistochemically, and biomechanically using a rat femur open fracture injury model.
Methods: 32 male Wistar-Albino rats were used and divided into two groups: the study group (VA) and the control group. From the time they were operated on until they were sacrificed, the rats in the study group were given 100 mg/kg/day VA by oral gavage.
Does the ulnohumeral angle have a role in the aetiopathogenesis of lateral epicondylitis?
Medicine (Baltimore)
April 2024
The pathophysiology of lateral epicondylitis (LE) remains not fully elucidated, as it involves a complex interaction of anatomical structures. The primary objective of the research is to identify a potential relationship between LE and the ulnohumeral angle (UHA), which demonstrates the coronal alignment of the elbow. Patients diagnosed with LE between September 1st, 2020, and September 1st, 2023, were retrospectively examined.

- The study assesses the effectiveness of single-plate (SP) versus double-plate (DP) fixation methods for treating complicated clavicle fractures, examining factors like union rates and complications over at least one year.
- The research included 27 patients treated with SP and 23 with DP, finding no significant differences in overall outcomes, including recovery time and complication rates at one year.
- Notably, the DP group had a quicker return to work and better early functional scores, while the SP group outperformed in ASES scores during the early months post-surgery, suggesting both methods are effective but with some differences in early recovery outcomes.
Objectives: This study aims to examine the effect of caffeic acid on tendon healing histopathologically and biomechanically in rats with an Achilles tendon injury model.
Materials And Methods: Twenty male Wistar-albino rats were used in this study. The rats were divided into two groups as the experimental group and control group.
Do lateral ankle ligaments contribute to syndesmotic stability: a finite element analysis study.
Comput Methods Biomech Biomed Engin
October 2024
Whether the lateral ankle ligaments contribute to syndesmotic stability is still controversial and has been the subject of frequent research recently. In our study, we tried to elucidate this situation using the finite element analysis method. Intact model and thirteen different injury models were created to simulate injuries of the lateral ankle ligaments (ATFL, CFL, PTFL), injuries of the syndesmotic ligaments (AITFL, IOL, PITFL) and their combined injuries.

In our study, we aimed to evaluate ideal fixation method in syndesmotic injury by using finite element analysis method. A 3D SolidWorks model file was created by taking computed tomography (CT) images of the area from the right foot base to the knee joint level of a healthy adult male.

J Pak Med Assoc
September 2020
The basic surgical treatment for avascular necrosis of the femur head is core decompression. In this report we discuss a case where the patient developed compartment syndrome after core decompression surgery with history of anticoagulant use. A 49-year-old man, who was using Coumadin 5 mg once daily due to aortic valve replacement and atrial fibrillation, had undergone core decompression surgery done due to stage 2 femur head avascular necrosis (AVN).
