Assessing potential factors leading to perioperative peri-implant fracture in femoral pertrochanteric fracture osteosynthesis using the proximal femoral nail antirotation 2: A retrospective study.

Background: Perioperative peri-implant fractures (PPIFs) pose infrequent yet significant challenges in orthopedic surgery, particularly in the context of femoral pertrochanteric fractures (FPF) treated with proximal femoral nail antirotation 2 (PFNA-2) nails. PPIFs can lead to prolonged recovery and may necessitate re-osteosynthesis in severe cases. Despite the effectiveness of PFNA-2 in the management of FPFs, our understanding of PPIFs in this specific context remains limited.

The double-plate fixation technique prevents varus collapse in AO type C3 supra-intercondylar fracture of the distal femur.

Introduction: Varus collapse followed by osteosynthesis for distal femoral fractures with conventional implants has been well documented but is seldom mentioned in fractures managed with locking plates. The purpose of this study was to assess the incidence of varus collapse after treating complex supra-intercondylar fractures of the distal femur (AO type C3) using a Single Plate (SP) or Double Plate (DP) fixation technique.

Materials And Methods: We retrospectively reviewed 357 patients with distal femoral fractures who were treated at our hospital between 2006 and 2017.

Causes of Increased Use of Closed Reduction and Internal Fixation for High-Energy-Related Traumatic Sacral Fractures.

Background: Reasons for the increased use of closed reduction and internal fixation (CRIF) for traumatic sacral fractures (SFs) are unclear in the literature. Therefore, we aimed to report the annual changes in the number of patients, mechanisms of injury, fracture patterns, and fixation methods.

Methods: In this retrospective study, we extracted data of 271 patients (mean age, 37.

Combined Effects of Cognitive Impairment and Nutritional Trajectories on Functional Recovery for Older Patients after Hip-Fracture Surgery.

Objectives: Malnutrition and cognitive impairment are associated with poor functional recovery in older adults following hip-fracture surgery. This study examined the combined effects of cognitive impairment and nutritional trajectories on postoperative functional recovery for older adults following hip-fracture surgery.

Design: Prospective longitudinal correlational study.

Simultaneous reduction and fixation of concomitant acetabular fracture and ipsilateral sacroiliac joint injury through the pararectus approach: a technical report and early radiological outcome.

Purpose: Osteosynthesis for acetabular fractures with ipsilateral sacroiliac joint (SIJ) injuries remains challenging for orthopedic surgeons, despite the evolution of surgical approaches, such as the pararectus approach, and treatment sequences. The study aimed to describe the details of the treatment of acetabular fracture with ipsilateral SIJ injury by the pararectus approach and to report its surgical outcomes.

Methods: We retrospectively assessed patients with acetabular fractures and ipsilateral SIJ injuries undergoing osteosynthesis by the pararectus approach over a three-year period.

Trunk Movement and Sequential Trunk Muscle Activation During Oscillation Exercises Using Flexible Poles.

Objectives: Oscillatory exercises using flexible poles, such as the Flexi-bar, were recommended as rehabilitation programs to increase trunk muscles strength; however, the strategy to enhance the training effects is under investigations. The aim of this study was to characterize the trunk movements and muscle activation patterns when performing an oscillation exercise with flexible poles in different weights.

Methods: Twelve healthy male participants performed oscillation exercises with flexible poles of different weights.

Percutaneous iliosacral screw and trans-iliac trans-sacral screw with single C-arm fluoroscope intensifier is a safe treatment for pelvic ring injuries.

To elucidate the accuracy, efficacy, and safety of percutaneous iliosacral screw (ISS) and trans-iliac trans-sacral screw (TITS) insertion using a single C-arm fluoroscopy intensifier. Additionally, the potential risk factors that might cause mal-positioned screws were identified. Patients with pelvic ring injuries who underwent percutaneous screw fixation in a single medical institute were divided into an ISS group (n = 59) and a TITS group (n = 62) and assessed.

Ultrasensitive Detection of Alzheimer's Amyloids on a Plasmonic-Gold Platform.

More than 55 million people live with dementia worldwide in 2021, and there are nearly 10 million new cases every year. Alzheimer's disease (AD) is the most common cause of dementia. Despite urgent need, early detection of AD and long-term monitoring of AD progression have been challenging.

Foramen ovale cannulation guided by intraoperative computed tomography with magnetic resonance image fusion plays a role in improving the long-term outcome of percutaneous radiofrequency trigeminal rhizotomy.

Background: Percutaneous radiofrequency trigeminal rhizotomy (RF-TR) is a well-established treatment for patients suffering from trigeminal neuralgia (TN) as a primary modality or for those refractory to medical treatment. However, few existing studies have identified intraoperative parameter or navigation technique that can be used to predict the rates of short-term or long-term pain relief. In this study, we analyzed patient characteristics, intraoperative parameters and technical factors, and postoperative changes in relation to immediate and long-term pain relief.

Endoscopic Harvest of Autogenous Gracilis and Semitendinosus Tendons.

The hamstring autograft is one of the most popular grafts for anterior cruciate ligament (ACL) reconstruction. Although many techniques for arthroscopic ACL reconstruction using hamstring autografts have been invented, hamstring harvest techniques have not been focused. Hamstrings are harvested using an open technique that requires a 2- to 5-cm skin incision.

A novel implant removal technique by endoscopy.

Background: Routine implant removal after fracture healing remains controversial. However, it has been suggested that implant removal should be performed in cases of joint impingement, painful scar adhesion, and implant malposition. Entrance selection is relatively critical in patients with poor soft tissue conditions or sloughing coverage.
