五十肘 四十肘

五十肩、四十肩が有名ですが、肩の痛みだけでなく、肘の痛みまで誘発することがあります。ふとした動作で、肘に痛みが走った、五十肘、四十肘は、上腕骨外側上顆炎という肘外側に起こる腱付着部の炎症や損傷です。テニスでバックハンドを打つ際に痛めることが多いので、テニス肘とも呼ばれています。上腕骨外側上顆炎はテニスやゴルフの愛好家のあいだでは頻発する痛みです。テニスのバックハンドを打つ際、ラケットを持っている腕を、手首ごと手の甲側に持ち上げる動きをすると、主に短橈側手根伸筋という筋肉の腱が、骨から始まる肘外側部分、上腕骨外側上顆に何度も牽引負荷がかかり、同部位が損傷して痛みがでるようになります。テニス肘を痛めると、手の甲を上にした状態で物をつかんだり、タオルを絞る動作などで手首や指に力を入れたりしたときに肘の外側に痛みを感じるという。しかもテニスやゴルフ経験がなくても、40代、50代になると上腕骨外側上顆炎を発症しやすいです。上腕骨外側上顆炎の主な発症原因は、加齢によって筋肉のしなやかさが低下すること、手関節伸筋の腱付着部の劣化（退行変性や加齢変性）が原因とされています。テニス、ゴルフ、作業時での酷使など、使いすぎもありますが、加齢の影響が中高年層の発症の多くを占めます。四十肘、五十肘の治療では日常生活で痛みを起こす動作である、手の甲が上になった状態で物をつかむことは避けてください。肘がさらに痛みます。手のひらが上を向いている状態で物を持ち上げると痛まないので、手の向きに意識して物を持ちましょう。長橈側手根伸筋、短橈側手根伸筋が関係している人差し指、中指は使わないように注意すると痛みが軽減できます。
Fifty and forty shoulders are well-known, but they can induce not only shoulder pain but also elbow pain. Fifty and forty elbow pain is caused by inflammation and damage to the tendon attachments on the outer side of the elbow called lateral epicondylitis of the humerus. It is also called tennis elbow because it often hurts when hitting a backhand in tennis. Lateral epicondylitis of the humerus is a common pain among tennis and golf enthusiasts. When hitting a backhand tennis ball, the arm holding the racket is lifted by the wrist toward the back of the hand. The tendon of the extensor carpi radialis muscle, primarily the short radial carpus muscle, is repeatedly pulled against the lateral humeral epicondyle, the part of the elbow that begins at the bone, causing damage and pain. If you suffer from tennis elbow, you will feel pain on the outer side of the elbow when you grab an object with the back of your hand up, or when you exert pressure on your wrist or fingers in actions such as squeezing a towel. Moreover, even if you have never played tennis or golf, you are more likely to develop lateral epicondylitis of the humerus in your 40s or 50s. The main causes of lateral epicondylitis of the humerus are the loss of muscle suppleness with age and the deterioration of the tendon attachments of the extensor tendons of the wrist joint (degenerative degeneration or age-related degeneration). Although overuse, such as in tennis, golf, and overuse at work, aging is responsible for the majority of cases in middle-aged and older adults. In the treatment of 40 and 50 elbow, patients should avoid grasping objects with the back of the hand up, a movement that causes pain in daily life. The elbow will hurt even more. Lifting objects with the palm of the hand facing up does not cause pain, so be aware of the direction of the hand and hold objects. Be careful not to use the index and middle fingers, which are related to the extensor carpi radialis longus and extensor carpi radialis shortus, to reduce pain.
