There are many causes of heel pain disorders, often accompanied by bone spurs on the anterior border of the heel tuberosity, mostly seen in middle-aged and older adults over 40 years of age. It mainly includes diseases such as subacromial bursitis, fasciitis at the beginning of the metatarsal tendon, laceration of the stop of the posterior Achilles tendon, and subacromial fat pad inflammation. From February 2005 to August 2007, the author used needle knife minimally invasive release surgery to treat heel pain with remarkable efficacy, which is reported below. 1. Clinical data (1) General data 96 patients were outpatients of our department, randomly divided into treatment group and control group. The treatment group consisted of 56 cases and 78 feet, with an average age of 52 years; the duration of the disease ranged from 2 weeks to 6 years, and the average duration of the disease was 6 months. The control group consisted of 42 cases with 58 feet, mean age 53.5 years, duration of disease 10 days-4 years, mean duration of disease 5.5 months. The clinical data such as gender, age and disease duration of the two groups were statistically analyzed, and there was no significant difference and were comparable. (2) Diagnostic criteria Referring to the “Guidelines for Clinical Research on New Chinese Medicines (2002)” and the “Diagnostic and Efficacy Criteria for Chinese Medicine” implemented in 1995, the following criteria were used: ① Pain under the heel, heavier when standing in the morning, relieved after a few moments of walking, but the pain increased after walking for a long time. (2) There is obvious pressure pain below the anterior heel node, and there are also pressure pains seen in the anterior lateral and medial heel. (3) X-ray shows bone spur formation in front of the heel node or a strip of calcium shadow at the midpoint of the arch, excluding bone lesions. However, those with pain may not always have bone spurs. (3) Case inclusion criteria Age 40-80 years old, meeting the above diagnostic criteria, belonging to the TCM evidence classification of liver and kidney deficiency; voluntarily participating in this trial and signing the informed consent form, with good compliance. (4) Case exclusion criteria Exclude other foot diseases, such as heel hypertension, gout, fracture, tumor, etc.; exclude patients with combined cardiovascular, cerebrovascular, liver, kidney, hematopoietic system, endocrine system and other serious primary diseases and psychiatric disorders. 2.Treatment method (1) Treatment group The Hanzhang needle knife produced by Beijing Huaxia Needle Knife Medical Equipment Factory was used. The patient lies prone on the bed with the heel facing upward and a soft pad under both feet. Make a mark at the most obvious point of pressure pain as the needle entry point. Routine disinfection with iodine and alcohol was performed, and local anesthesia was performed with 5 ml of 1% lidocaine. Select a No. 4 needle knife, needle knife mouth line and foot longitudinal axis direction, vertical stabbing up to the heel bone surface, first longitudinal cutting several knives, and then transverse cutting swing, feel the needle knife under the loose feeling out of the needle knife, and then inject tretinoin injection 0.3ml local closure, compression to stop bleeding, band-aid dressing needle eye. Once a week, 3 weeks for a course of treatment. (2) Control group Use 1% lidocaine 2ml plus trimethoprim injection 0.3ml, do painful point closure, once a week, 3 weeks as a course of treatment. All the two groups were followed up, and the follow-up time was from 6 months to 2 years, with an average of 11.2 months. 3. Observation indexes and efficacy criteria (1) Main observation indexes Pain was judged by the VAS (visual analogue scales) visual analogue scale for pain changes in the heel (VAS: 0-10, 0 being no pain, 10 being the most painful), pressure pain, functional impairment and insomnia. The efficacy was evaluated with 3 months as one observation cycle, followed by regular follow-up every 3 months. The grading and quantification standards of observation indexes were formulated with reference to the Guiding Principles for Clinical Research on New Chinese Medicines (2002). (2) Efficacy criteria The criteria were formulated according to the “Guidelines for Clinical Research on New Chinese Medicines (2002)”. The formula is: [(pre-treatment score – post-treatment score) ÷ pre-treatment score] × 100%. Cured: disappearance of heel pain, no pain in the morning or during walking, and ≥95% reduction in the symptom-sign score. Significant effect: no pain in the heel, slightly painful in the morning or when walking, close to normal function, ≥70% reduction of symptoms and signs points, <95%. Improvement: light pressure pain in the heel, still painful when walking, but less than before treatment, ≥30% and <70% reduction in the symptom score. Ineffective: no change in clinical symptoms, reduction of symptoms and signs by <30%. 4, treatment results The efficacy of the two groups of cases was counted after 6 months of follow-up, and the data were statistically processed and analyzed by applying SPSS12.0 software, and there was a significant difference in the healing rate between the two groups.
