親指捻挫　

thumb sprain　

親指の付け根分に痛みがあり、親指の、人差し指側の付け根を触ると熱感と疼痛があり、他の指に比べて、親指を動かすと痛みが生じるため、可動域が減少してると感じて来院。親指の靭帯の怪我で最も多いのは、親指の内側側副靭帯・尺骨側副靭帯の損傷です。この靭帯は親指の真ん中の関節・中手指節関節に付着し非常に強く、親指を安定させて、物をはさんだり、つかんだりすることができますが、この優れた可動域や動きがあるため、その代償として、安定性が、他の指に比べてありません。動きに富む分、他の指に比べて捻挫や脱臼や靭帯損傷を起こしやすいです。一番多い原因としては、親指を外側に向けて大きく曲げすぎてしまうことです。繰り返しの掴む動作、あるいは捻る動作で徐々に靭帯を痛めていくことがあります。柔道などでは、胴衣のつかみ合いの中、相手選手が技をかわすため体を捻る動作が多いと、四指では第一関節を、親指には内側側副靭帯のストレスがかかり、親指を支えている靭帯が伸びたりすると指の不安定性と疼痛が症状にでます。。鍼灸治療としては、血行を促進して、鎮静・消炎させ、疼痛緩和と、血流の乏しい靭帯や腱に栄養を与えて回復を早めていきます。

The patient came to the clinic with pain at the base of the thumb, heat and pain when touching the base of the index finger side of the thumb, and pain when moving the thumb compared to the other fingers, and felt that the range of motion was decreased. The most common ligament injury of the thumb is damage to the medial and ulnar collateral ligaments of the thumb. These ligaments attach to the middle joint of the thumb, the metacarpophalangeal joint, and are very strong, stabilizing the thumb and allowing it to pinch and grasp, but this superior range of motion and movement comes at the cost of less stability than the other fingers. Because of this superior range of motion, the thumb is more prone to sprains, dislocations, and ligament injuries than other fingers. The most common cause is an overbending of the thumb too far outward. Repetitive gripping or twisting movements can gradually damage the ligaments. In judo and other sports, when an opponent often twists his body to dodge techniques during a grapple for body armor, stress is placed on the first joint in the fourth finger and on the medial collateral ligament in the thumb, and if the ligament supporting the thumb is stretched, instability and pain in the finger can be a symptom. Acupuncture and moxibustion treatment is used to stimulate blood circulation, soothe and eliminate inflammation, relieve pain, and nourish the ligaments and tendons with poor blood flow to speed recovery.
