親指　CM関節症

Thumb pain CM arthritis CM jojnt

ガーデンニングで、ハサミを使う時に親指の付け根に痛みがでていた。放置していたら、次第に強い痛みを感じて来院となった。ハサミなどで母指を広げる時や、物をつまむ時やビンのふたを開ける時など、母指に力を必要とする動作で痛みがでるとのこと。母指のCM関節・第1手根中手骨関節は、母指の手前・甲側の骨（第1中手骨）と手首の小さい骨（大菱形骨）の間の関節で、母指は他の指と向き合って、つまみ、握り、母指を固定して四指でひねるなど、大きな動きのできる関節なので、他の指に比べて、動作が大きい分、関節損傷を受けやすいです。母指の使い過ぎや加齢変性に伴って、関節軟骨の摩耗が起き易く、進行すると関節が腫れたり、今回のように痛みがでます。次第に、摩耗した関節部分が、不安定になり、亜脱臼したり、母指が変形てスワンネックのような形態になったりします。鍼灸治療では、血行を促進して、血流を改善し、炎症のある関節の、消炎、鎮痛、鎮静をはかり、関節を支える筋肉へ栄養を運び、筋緊張を緩和して、症状の改善と悪化を予防します

When using scissors for gardening, he had pain at the base of his thumb. If left untreated, the pain gradually became more severe and she came to the clinic. She said that the pain occurred when she spread her thumb with scissors, or when she used it to pick up an object or open a bottle lid, or any other action that required force on the thumb. The CM joint and first carpometacarpal joint of the thumb is the joint between the bones on the front and instep side of the thumb (first metacarpal bone) and the smaller bones of the wrist (greater rhomboid bone). The thumb faces other fingers and can make large movements such as pinching, grasping, fixing the thumb and twisting with all four fingers, so compared to other fingers, the greater movement makes the joint more Therefore, it is more susceptible to joint damage than other fingers. The joint cartilage is prone to wear and tear due to overuse and age-related degeneration of the thumb, and as the process progresses, the joint becomes swollen and painful, as seen in this case. Gradually, the worn joints become unstable and subluxated, or the thumb becomes deformed and has a swan-neck-like shape. Acupuncture and moxibustion treatment improves blood circulation and blood flow, and it also provides anti-inflammation, analgesia, and sedation to the inflamed joints, and nourishes the muscles that support the joints and relieves muscle tension, thereby improving symptoms and preventing them from worsening.
