1, tennis elbow Tennis elbow, also known as humeral epicondylitis, humeral epicondyle syndrome, lateral elbow pain syndrome, and humeral epicondyle osteochondritis, is a chronic injury myofasciitis at the extensor generalis tendon of the humeral epicondyle, and is the most common chronic injury elbow disease. Symptoms: The main manifestation is limited soreness of the lateral elbow joint with varying degrees of pain, which can spread to the radial side of the forearm and the wrist. The pain may spread to the radial side of the forearm and the wrist. A few of them may spread to the upper arm and shoulder, and the pain may gradually worsen. The pain can be aggravated by activities such as wringing towels and pouring water from warm bottles, and can be relieved by rest. On examination, there is obvious pressure pain at the lateral epicondyle of the humerus, as well as at the annular ligament and the humeral radial joint space, and there are also local palpable strips and sclerotomes with obvious tenderness. Treatment: At the most obvious place of pressure pain, the incision line of the small needle knife is stabbed parallel to the direction of the wrist extensor muscle into the subcutaneous external epicondyle of the humerus, and treated by lifting and inserting, puncture release, longitudinal release and spade release method. The operation takes only 1 minute and can be healed in 1~2 times. If multiple treatments are needed, the interval should be 5~7 days. 2, radial stenosis tenosynovitis is a chronic aseptic inflammation of the tendon sheath of the radial stenosis caused by mechanical friction. The repetitive inflammatory stimulation narrows the tendon sheath. Pain occurs due to repeated friction between the tendon sheath and the tendon, and in severe cases, wrist movement and thumb extension are limited to varying degrees. The disease is more common, with significantly more women than men. Symptoms: The onset of the disease is slow, with gradual aggravation, but there are also sudden onset of symptoms. The main manifestation is limited pain at the radial styloid process, which can be radiated to the thumb or elbow, and the pain increases when moving the wrist and thumb. On examination, there is obvious pressure pain at the radial tuberosity, and a hard node can be palpated under the skin locally. Treatment: Firstly, the most obvious pressure pain at the radial styloid process was fixed, routinely disinfected, firstly, local closure was done, and then needle knife was used to loosen it. The needle knife line is parallel to the tendon, pierce the skin, reach the tendon sheath, and do longitudinal release, then, the needle knife reaches the bone surface, and do oblique spade release. Generally 1~2 times can be healed. For those who need multiple treatments, the interval is 5~7 days. 3, popping finger Popping finger, also known as “trigger finger”, “flexor tendon stenosis tenosynovitis”, refers to the flexor tendon and its fibrous sheath tube due to repeated injury and aseptic inflammation, mainly manifested as the metacarpophalangeal joint popping and pain, mostly seen in manual laborers of the thumb, middle The pain is usually seen in the thumb, middle and ring finger of manual workers. Symptoms: Early in the morning, the metacarpophalangeal joint is sore and uncomfortable, and the fingers are stiff and inflexible, which can disappear after activity. After work, finger movement is limited, and there may be limited soreness on the palmar side of the metacarpophalangeal joint. As the disease progresses, the local pain increases and sometimes radiates to the wrist. In severe cases, the finger is stuck in extension or flexion position, resulting in “locking” phenomenon, which can only be “unlocked” by passive flexion or extension, and popping sounds occur, which obviously affects the finger activities. Treatment: In the palmar side of the metacarpophalangeal joint into the needle, first local painful point closed, the doctor can feel the flow of fluid along the tendon sheath to the distal side, tendon sheath expansion. Then, the doctor can feel the flow of medicine along the distal side of the tendon sheath and the expansion of the tendon sheath. Once loosened, the popping phenomenon is immediately relieved. The treatment process can be completed in 3~5 minutes, and usually heals in 1 treatment session. 4, medial collateral ligament injury of the knee joint A painful disease caused by acute violent injury and sustained static injury, resulting in damage to the medial collateral ligament of the knee. Symptoms: (1) There is a clear history of trauma, and at the time of injury there is severe tearing pain in the knee with limited movement. On palpation, the torn ligament can be palpated as a striated bulge or depression, with sharp cracking pressure pain. Positive external calf displacement test. (2) Static injury patients have a history of persistent static pulling, mainly presenting with intractable pain in the medial knee, in the medial femoral epicondyle or medial tibial condyle, and sometimes small subcutaneous nodules can be palpated. Treatment: (1) Patients with acute injuries should be braked first, and local cold compresses can be applied to reduce internal bleeding. For complete rupture of the ligament, early surgical treatment should be performed. (2) chronic stage or static injury patients, in the medial collateral ligament starting point or injury to find the pressure point, local skin disinfection after local anesthesia, small needle knife blade and ligament direction parallel stabbing, with lifting and inserting, puncture loosening method of treatment. If the lesion is at the starting and stopping point of the ligament, the longitudinal release method and the spade release method are used. Treatment once a week, generally 2~3 times can be cured. 5, patellar ligament injury is due to improper knee joint activities, resulting in damage to the patellar ligament stop. After an acute injury, there is a partial fiber avulsion or tear at the attachment of the tibial tuberosity, and over time, chronic aseptic inflammation is formed, causing persistent chronic pain. Symptoms: pain at the attachment point of the patellar ligament and the tibial ramus, difficulty in straightening the knee joint, limp when walking, and increased pain when going down steps. Treatment: Find the pressure point at the attachment point of patellar ligament and tibial ramus, disinfect routinely, after local anesthesia, stab the small needle knife blade perpendicularly parallel to the patellar ligament direction, and use the lifting and inserting, puncturing and loosening method, longitudinal stripping method and transverse spade stripping method. Treatment once a week, usually 1~2 times can be cured. 6, infrapatellar fat pad injury Infrapatellar fat pad injury is also known as infrapatellar fat pad inflammation and infrapatellar fat pad hypertrophy. The onset is slow, with anterior patellar pain and limited knee function as the main manifestation. Symptoms: The onset is slow, with initial knee discomfort, soreness, pain, weakness, and coldness, and pain is more obvious when going up and down stairs. The pain gradually worsens and becomes heavier, eventually leading to persistent anterior infrapatellar pain. The knee was limited in hyperextension and hyperflexion, with pressure pain at the inferior border of the patella (+) and deep pressure pain at the midpoint of the patellar ligament (+). Treatment: search for pressure pain points, routine disinfection, local closure first, then small needle knife therapy operation. (1) For obvious pain at the lower edge of the patella, the patient takes a supine position with knees extended, and the doctor uses the left thumb and index finger to separate and push the upper edge of the patella distally, so that the lower edge is upturned. The right hand holds a small needle knife with the blade running parallel to the patellar ligament and pierces the inferior patellar edge and its posterior edge, performing longitudinal release, fan release and spade stripping. (2) With obvious pressure pain at the midpoint of the patellar ligament, the patient was made to lie supine and bend the knee at 90°, the blade was parallel to the patellar ligament, and the needle was inserted vertically at the pressure pain point. The junction of the patellar ligament and fat pad was reached, and different angles of longitudinal release and fan release were performed. 7, heel pain (heel spur, heel subacromial bursitis, heel subfat pad inflammation) Mostly due to heel spur (plantar fascia bursitis), heel subfat pad strain and other reasons, resulting in related aseptic inflammation and heel pain. It is mainly caused by long distance walking, or prolonged standing, or improper shoe wear. Symptoms: pain under the front of the heel or under the heel, aggravated by walking. In mild cases, there may be only discomfort, but in severe cases, there is sharp pain like tearing, and even the heel cannot land when walking. Examination may reveal pressure pain under or in front of the heel. Treatment: Local anesthesia is first applied to the most painful area, and then the needle is inserted vertically and treated by lifting and inserting, puncturing and loosening, longitudinal loosening and spade loosening. Generally 1~2 times can be cured, and for those who need multiple treatments, the treatment interval is 5~7 days. 8, the third lumbar transverse synovial syndrome method: in the obvious pressure pain, longitudinal stabbing with a small needle knife, first with the lifting and inserting, puncture loosening method, when the knife touches the bone surface, switch to the transverse spade stripping method, feel a sense of loosening between the muscle and the bone surface can be released needle. Generally 1~2 times can be healed, treatment interval 5~7 days. 9, lumbar muscle strain Method: Because of the large range of pain, it is appropriate to find the more obvious parts of the pressure pain treatment. The operation can be treated by lifting and inserting, puncturing and loosening method, and longitudinal loosening method.
