Flexor tendon stenosing tenosynovitis release

The flexor tendon stenosis tenosynovitis, also known as the "board machine finger", is a common disease in orthopedic surgery. More common in middle-aged and elderly women and manual laborers, this disease can affect the daily work and life of patients. Since the 1980s, many doctors in China have made great progress in treating this disease with traditional acupuncture and moxibustion treatment. Because this therapy has the characteristics of economy, easy operation, and quick recovery, it has been continuously promoted. Moreover, in recent years, many professionals in various places have made some useful attempts and improvements in the preparation of needle-knife and the application techniques of cutting methods in medical practice, and achieved satisfactory results. Treatment of diseases: tenosynovitis of the fingers flexor tendon Indication (1) local pain of the affected finger; (2) The affected finger has a significant blockage when it is flexing and stretching, and there is a ringing; (3) The lock of the flexion and extension movement of the affected finger occurs; (4) The affected finger can partially touch the hard nodules under the skin. Contraindications A person with poor physical fitness who is not suitable for surgery. Preoperative preparation All patients were treated with Hanzhang Type I Needle Knife with a needle length of 50 mm and a needle tip width of 2 mm. The procedure was performed in an outpatient sterile operating room. The conventional finger skin was prepared for disinfection, and the treating physician found a significant tender point on the palmar side of the patient's metacarpal bone. And touch a nodule, with 1% lidocaine in this line local infiltration anesthesia, the drug should enter the tendon sheath, the therapist's left hand will fully stretch the finger to stretch, so that the flexor tendon is fully stressed. Surgical procedure (1) Needle knife and skin disinfection should be strictly carried out according to the requirements of aseptic surgical operation. (2) Accurate positioning: The part of the needle-knife cutting should be concentrated on the localized lesion tissue, that is, the first annular ligament of the flexor tendon sheath located near the metacarpophalangeal joint. The longitudinal cutting range of a needle knife with a width of about 7 to 9 mm should be fixed within 10 to 15 mm. Excessive cutting to the far side may damage the tendon of the tendon and affect the flexion and extension of the finger. In the 2 to 5 finger cutting treatment, it is necessary to prevent the cutting to the proximal side too much, causing the accidental injury of the shallow arch blood vessel. Needle knife cutting can only be cut longitudinally along the direction of the tendon, and must not be oblique and perpendicular to the direction of the tendon. complication Flexor tendon rupture, severe adhesion after tendon surgery, recurrence of tenosynovitis and nerve branch damage around the tendon.
