Relationship Between Foot Kinematics and Center of Pressure Trajectory During Gait in Individuals with Flatfoot.

Background: Flatfoot causes the medial shift of ground reaction force during the stance phase of gait, which is associated with various foot disorders. To prevent this shift in flatfoot, it is necessary to understand the characteristics of the loading pattern and what foot joint kinematics influence it. We investigated differences in the center of pressure (COP) position between normal foot and flatfoot, and predictors of COP trajectory during gait.

Medial meniscal extrusion with cumulative mechanical stress describes the clinical response of lateral wedge insoles for patients with knee osteoarthritis.

Background: Lateral wedge insole (LWI) is known to reduce abnormal mechanical stress in knee osteoarthritis; however, clinical improvement across cases varies. The increase in medial meniscal extrusion (⊿MME) during walking could describe the dysfunction of shock absolution and the reaction of mechanical stress in individual knee joints.

Objective: This study aimed to investigate whether the ⊿MME affects LWI responders.

Insufficient morphological changes in the infrapatellar fat pad during walking in patients who underwent anterior cruciate ligament reconstruction.

Background: The infrapatellar fat pad (IFP) plays the knee joint's buffers capacity based on flexible morphological changes under mechanical stress. Patients who underwent anterior cruciate ligament (ACL) reconstruction have insufficient IFP flexibility; however, morphological change under mechanical stress is still unknown.

Research Question: This study aimed to investigate the morphological change in IFP (ΔIFP) during walking and their correlation with mechanical stress in patients who underwent ACL reconstruction.

Debranching Thoracic Endovascular Aortic Repair (TEVAR) for Thoracoabdominal Aortic Dissecting Aneurysm Involving the Visceral Arteries: A Case Report.

Surgical repair of thoracoabdominal aortic aneurysms (TAAA) is a complex procedure that is associated with marked morbidity and mortality. Endovascular TAAA repair, initially reserved for patients at high risk, has yielded promising results and is performed on an increasing range of patients. This case report describes a hybrid approach-a combination of endovascular and open repair-for a patient with high-risk TAAA after aortic dissection.

The combination of initial Impella therapy, Impella-supported coronary artery bypass grafting (ISCAB), and postoperative Impella therapy providing antegrade perfusion in myocardial infarction can prove effective. We investigated strategies for Impella stabilization in ISCAB, particularly during peripheral circumflex branch anastomosis. Case 1 was a 70-year-old man treated with an Impella 2.

Medial meniscus extrusion during squatting is correlated with lower limb kinematics in patients with knee osteoarthritis.

Background: Increased medial meniscal extrusion (MME) under mechanical stress is a risk factor associated with progression of knee osteoarthritis (OA). Patients with knee OA often have unique features of abnormal kinematics during squatting, which might induce joint loading and increased MME; however, the detailed relationships involved remains unknown.

Research Question: In this study, we investigated the effects of knee kinematics on increased MME during squatting in patients with knee OA.

Ulnar finger posture effect on a pinch strength.

Upper extremity position affects maximum pinch strength; however, there is no consensus regarding the posture of the three ulnar fingers during pinch strength testing, and existing studies have different flexion or extension posture, depending on the measurement method used. This study aimed to clarify the effect of ulnar finger posture on maximum pinch strength and to verify its reliability. Thirty-three participants (19 males and 14 females) performed maximum pulp-to-pulp pinching with both dominant and non-dominant hands.

Surgical Outcomes of the Boat-Form Vein Cuff Technique in Peripheral Artery Bypass Grafting.

The venous cuff technique has been used primarily for arterial bypass using artificial grafts to the lower extremities. The boat-form vein cuff was designed to allow adjustment of the size and angle of the anastomosis at any anatomic site. We report our experience and outcomes of the original vein cuff technique in various peripheral artery bypass grafting procedures.

Effect of wider step-width gait on hip joint contact force.

Hip joint contact force (HJCF) overloading is a primary mechanical cause of hip osteoarthritis. Hip adduction moment (HAM) is a surrogate measure for estimating HJCF. Gait modification, especially wider step-width (SW), can significantly decrease the peaks and impulses of HAM, suggesting a possible strategy for preventing joint overloading.

Axillo-Femoral Bypass Followed by Pelvic Exenteration for Locally Advanced Sigmoid Colon Cancer Invading the Common Iliac Artery.

Introduction: Initially, unresectable locally advanced colorectal cancers are still not uncommon. Despite recently developed systemic treatment has extended the survival of patients with unresectable and recurrent disease, surgical resection offers the chance for a cure or long-term survival. Recently, with improvement in the safety of major vascular reconstruction, several reports have suggested that extended pelvic tumor resection with vascular reconstruction with curative intent can be performed safely; however, the indications for arterial vascular reconstruction remain controversial and are reported with a literature review.

Incomplete ablation as a mechanism of atrial fibrillation recurrence and atrial tachycardia development after maze procedure.

Objective: Atrial tachyarrhythmias are the most frequent complication after the maze procedure. We examined the mechanism of atrial tachyarrhythmias in association with the ablation energy and technique used at each lesion and by the findings of postoperative electrophysiological study.

Methods: Four-hundred fifty-three patients who underwent the maze procedure with biatrial incisions and bilateral pulmonary vein (PV) isolation were examined for the incidence and mechanism of recurrence of atrial fibrillation (AF) and development of atrial tachycardia (AT).

Dynamic feature of infrapatellar fat pad during walking in patients with knee osteoarthritis.

Purpose: The infrapatellar fat pad (IFP) absorbs mechanical stress in the knee joint owing to flexible morphological changes. The IFP is a key factor in knee osteoarthritis (OA); however, its dynamic feature during walking remains unknown. This study aimed to investigate whether the morphological changes in the IFP during walking involve specific features for patients with knee OA.

This study aimed to quantitatively evaluate peripheral nerve injury (PNI) after varicose vein (VV) surgery using endovenous laser ablation (EVLA). Overall, 25 cases were analyzed. All patients underwent EVLA of the great saphenous vein (GSV) with or without resection of the varix of the GSV tributaries in stab and avulsion fashion (microphlebectomy).

Photocatalytic Estrogen Degradation by the Composite of Tin Oxide Fine Particles and Graphene-like Carbon Nitride.

This study investigates whether 17β-estradiol (E2), a natural estrogen and one of the endocrine-disrupting chemicals responsible for water pollution, can be oxidatively decomposed under simulated solar light using a composite of tin oxide nanoparticles and graphene-like carbon nitride (g-CN) as a photocatalyst. The composite photocatalyst was prepared by heating a mixture of urea and tin acetate. FT-IR measurements revealed that g-CN possesses structural units similar to g-CN, a well-studied graphite-like carbon nitride.

Predictors of Gait Variability in Older Inpatients: An Exploratory Study Among Orthopedic Patients.

Life-Threatening Conditions and Preoperative Complications Associated with Cardiac Neoplasm Do Not Affect Surgical Outcomes or Mortality.

Cardiac neoplasms may cause life-threatening symptoms associated with cerebral infarction, ventricular arrhythmias, and heart failure. Emergency surgery or preoperative treatment may be required for these patients. However, no study has reported the surgical outcomes in cases involving cardiac neoplasms with life-threatening complications.

Individuals with asymptomatic hallux valgus exhibit altered foot kinematics during gait regardless of their foot posture.

Background: A flatfoot has been believed to be closely associated with the development of hallux valgus; however, the association is still controversial. Abnormal foot kinematics has been identified as a possible risk factor for the development of hallux valgus, but it remains unclear whether foot posture contributes to abnormal foot kinematics. This is the first study to investigate the differences in foot kinematics during gait between individuals with and without hallux valgus, while controlling for foot posture.
