まとめ
足首と第1メタタルソファランジアル関節 (MTP1) の位置は,Flexor Hallucis Longus (FHL) に著しく影響する.
科学分野:
- バイオメカニクス バイオメカニクス
- 整形外科 整形外科 整形外科
- 足と足首の外科手術
背景:
- Flexor Hallucis Longus (FHL) は,足の生体力学にとって極めて重要であり,歩行の安定性と第1次メタタソファランジアル関節 (MTP1) の屈曲に影響を与えます.
- 過剰なストレスは,特にアスリートにおいて,炎症や機能性ハルクス・リジダスなどのFHLの問題を引き起こす可能性があります.
- 足首とMTP1関節の動きがFHL動力学に与える正確な影響は完全に理解されていません.
研究 の 目的:
- 足首とMTP1関節の位置の関係と,FHLの逸脱に及ぼす影響を調査する.
- 異なる関節構成がFHL移位にどのように影響するかを分析する.
- 足首とMTP1の動きがの移動を大きく変化させ,足首の屈折が最も変化をもたらすという仮説を検証する.
主な方法:
- 9つの死体 (18フィート) の標本を使用しました.
- 縫合マーカーは,FHLのの近辺と遠端に,後部タラルパレーに配置されています.
- 足首の9つの位置 (中性,背筋屈折,足首屈折) とMTP1 (中性,背筋屈折,足首屈折) の組み合わせで測られた筋マーカーの移位.
主要な成果:
- 足首の足元屈折,特にMTP1足元屈折では,FHLの最大近接滑り (最大1.3±0.7cm) が引き起こされた.
- 足首を足下屈折状態にすると,MTP1の足下屈折は1.3 ± 0.7cm,中性MTP1は1.2 ± 0.4cm,MTP1の背筋屈折は0.44 ± 0.5cmの遠回りをもたらした.
- 足首とMTP1関節の位置は,FHL距離の変動に直接影響した.
結論:
- レトロタラー・プリーにおけるFHLのエクスクルションは,足首とMTP1関節の位置を組み合わせることで著しく影響を受けます.
- 足首の平部屈折は近辺FHLの滑り方を促し,背部屈折は遠端滑り方を促します.
- 発見は,静的,負荷のないモデルの限界にもかかわらず,足首とMTP1関節力学とFHLの行動の間の機械的な相互作用の理解を高める.

Ankle Joint
3.1K
The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...

Role of Affect in Interpersonal Attraction
240
Affect plays a crucial role in shaping interpersonal evaluations and perceptions. Emotions influence how individuals judge and respond to others, often determining whether interactions are viewed positively or negatively. This effect can manifest directly through interactions with the person in question or indirectly via associations with unrelated emotional experiences.Direct Effects of Affect on AttractionAffect directly influences interpersonal attraction when a person’s behavior...

Structural Joints: Synovial Joints
7.4K
Synovial joints are the most common type of joint in the body. A key structural characteristic for a synovial joint is the presence of a joint cavity. This fluid-filled space is where the articulating surfaces of the bones contact each other. Also, unlike fibrous or cartilaginous joints, the articulating bone surfaces at a synovial joint are not directly connected to each other with fibrous connective tissue or cartilage. This gives the bones of a synovial joint the ability to move smoothly...

Structural Joints: Fibrous Joints
3.9K
Fibrous joints are a type of joint where the bones are connected by fibrous connective tissue. These joints provide stability and minimal to no movement between the articulating bones. There are three types of fibrous joints.
Suture
All the bones of the skull, except for the mandible, are joined to each other by a fibrous joint called a suture. The fibrous connective tissue found at a suture strongly unites the adjacent skull bones and thus helps to protect the brain and form the face. In...

Structural Joints: Cartilaginous Joints
4.3K
As the name indicates, at a cartilaginous joint, the adjacent bones are united by cartilage, a tough but flexible type of connective tissue. Unlike synovial joints, these types of joints lack a joint cavity and involve bones joined together by either hyaline cartilage or fibrocartilage.
There are two types of cartilaginous joints:
Synchondrosis
A synchondrosis ("joined by cartilage") is a cartilaginous joint where bones are connected by hyaline cartilage. Synchondrosis may be temporary...

Joints
35.9K
Joints, also called articulations or articular surfaces, are points at which ligaments or other tissues connect adjacent bones. Joints permit movement and stability, and can be classified based on their structure or function.
Structural joint classifications are based on the material that makes up the joint as well as whether or not the joint contains a space between the bones. Joints are structurally classified as fibrous, cartilaginous, or synovial.
Fibrous Joints Are Immovable
