External humeral epicondylitis is also known as external humeral epicondyle syndrome or “tennis elbow”. The lateral epicondyle of the humerus is the attachment of the common tendon of the radius. If the forearm is rotated in the anterior position, the wrist joint is often used for dorsiflexion activities, which may cause injury to the soft tissues at the attachment site, resulting in local bleeding and adhesions, or even pain due to the synovial membrane embedded in the brachioradialis joint space. The onset of the disease can be caused by acute sprain or strain, but most patients have a slow onset, usually without obvious history of trauma, mostly seen in adults who need to repeatedly rotate the forearm and forcefully extend the wrist, mostly on the right side. 1. Diagnosis 1.1 Clinical manifestations 1.1.1 Symptoms: pain near the external epicondyle of the humerus and the brachioradialis joint, especially when the forearm is rotated and the wrist joint is actively dorsiflexed, the pain is more obvious and radiates downward along the wrist extensor muscle. The local area may be slightly swollen. 1.1.2 Signs 1.1.2.1 Compression pain: marked pressure pain at the external epicondyle of the humerus and at the brachioradialis joint, as well as extensive pressure pain along the direction of wrist extension muscle travel. 1.1.2.2 Positive wrist extension resistance and tennis elbow test. 1.2 Diagnostic criteria 1.2.1 Significant pressure pain at the lateral epicondyle of the humerus and at the brachioradialis joint. 1.2.2 Positive wrist extension resistance and tennis elbow test. 2. Identification Due to acute and chronic injury, the local meridians of the elbow joint are damaged, the qi and blood are stagnant and obstructed, the tendons and veins are not moistened, and the blood is blocked in the meridians, which causes pain. 3.Treatment 3.1 Treatment principle: Relieve tendons and channels, activate blood circulation and remove blood stasis. 3.2 Technique: one-finger meditation pushing, kneading, pointing, pressing, holding, rubbing, etc. 3.3 Acupuncture points: Quchi, Waiguan, Hand Sanli, He Gu. 3.4 Operation: The patient is sitting upright. The doctor sits on the patient’s side of the disease, taking the right upper limb as an example. The doctor holds the patient’s right wrist in a rotated posterior position, presses the thumb of the left hand against the anterior aspect of the external humeral epicondyle, and places the other four fingers on the medial side of the elbow joint; the doctor gradually flexes the patient’s elbow joint with the right hand to the maximum, and presses the patient’s external humeral epicondyle with the thumb of the left hand. The doctor gradually flexes the patient’s elbow joint with the right hand to the maximum, and then straightens the patient’s elbow joint, while the doctor pushes the left thumb to the front of the radial head of the affected limb and flicks the starting point of the wrist extensor muscle backward along the front outer edge of the radial head; repeatedly flicks several times. Then, press and knead the Quchi, Waiguan and Hand Sanli points to the extent of soreness and swelling. Finally, rub the elbow around the lateral humeral epicondyle and forearm extensor muscle group with rubbing method. 3.5 . Other treatments 3.5.1 External application of drugs: blood activating powder is applied externally. 3.5.2 Drug patch: commonly used are dog skin ointment, Qizheng pain relief patch, Doc’s self-heating patch, blood-vitalizing bone patch, etc. 3.5.3 Acupuncture and moxibustion therapy: it has good curative effect, and it works better with Tui Na. 3.5.4 Closed therapy: fast effect, easy to recur. The symptoms of this disease are obviously aggravated by cold. Therefore, attention should be paid to local warmth, avoid cold stimulation, and the wrist should not do hard back extension activities during treatment.
