まとめ
集束性体外衝撃波療法(fESWT)は、母指手根中手関節症(CMC)の患者の疼痛を効果的に軽減し、機能を改善しました。fESWTを示す効果は1年まで持続しました。
科学分野:
- 整形外科学; 再生医療; 筋骨格系疾患
背景:
- 変形性関節症(OA)は関節に影響を与え、母指手根中手関節症(CMC OA)は著しい疼痛と機能制限を引き起こします。; 母指CMCOAにおける衝撃波療法の証拠は限られており、さらなる調査が必要です。; 従来の治療法や手術は、すべてのOA患者に適しているわけではありません。
研究 の 目的:
- 母指CMCOAに対する集束性体外衝撃波療法(fESWT)の有効性を評価すること。; fESWT後の疼痛軽減と機能改善を評価すること。; この患者集団におけるfESWTの安全性と忍容性を判断すること。
主な方法:
- 両側母指CMCOAを有する64歳女性患者を対象とした単臂、症例研究デザイン。; エネルギー流束密度を個別に調整したfESWTを週3回実施。; 治療後最大52週までの複数の時点でのQuickDASHスコアと握力を含むアウトカム評価。
主要な成果:
- fESWTは忍容性が高く、有害事象の報告はありませんでした。; QuickDASHスコアはベースラインの20.5から52週で2.3に有意に改善しました。; 握力は右手で29.5%、左手で17.4%増加し、1年後も主観的な改善が持続しました。
結論:
- 個別化されたfESWTは、母指CMCOAに対する安全で効果的な非侵襲的治療法として可能性を示しています。; 介入後12ヶ月まで疼痛と機能の持続的な改善が観察されました。; これらの所見を確認し、治療プロトコルを最適化するために、より大規模な対照研究によるさらなる研究が保証されます。

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.

Introduction to Joints
4.8K
The adult human body usually has 206 bones, and except for the hyoid bone in the neck, each bone is connected to at least one other bone. Joints are the location where bones come together. Many joints allow for movement between the bones. At these joints, the articulating surfaces of the adjacent bones can move smoothly against each other. However, the bones of other joints may be joined by connective tissue or cartilage. These joints are designed for stability and provide little or no...

Structural Joints: Fibrous Joints
3.7K
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
4.0K
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...

Structural Joints: Synovial Joints
6.8K
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...

Method of Joints
1.3K
The method of joints is a commonly used technique to analyze the forces in structural trusses. The method is based on the principle of equilibrium, which assumes that the truss members are connected by frictionless pins. The forces at each joint can be determined by considering the equilibrium of the forces acting on that joint.
Since plane truss members are in the same plane, each joint is subjected to a coplanar and concurrent force system. To apply the method of joints, the first step is to...
