Ultrasound-Guided Inactivation of Trigger Points Combined with Muscle Fascia Stripping by Liquid Knife in Treatment of Postherpetic Neuralgia Complicated with Abdominal Myofascial Pain Syndrome: A Prospective and Controlled Clinical Study

Figure 1

Ultrasound-guided inactivation of trigger points and muscle fascia stripping by liquid knife. The body was examined in advance and marked on the skin with definite tenderness points. The marking points were located in the center of the ultrasonic probe and guided in real time by in-plane technology. (a) Solid triangle refers to the trigger point of the muscle. (b, c) Hollow arrow indicates the tip of the needle, and the trigger point was punctured repeatedly until the patient’s aching and distending pain was significantly alleviated and the induced muscle convulsion disappeared. (d) After inactivation of the trigger point, the local echo brightness decreased. (e) Wet needle: liquid of 1 ml was injected into the trigger point, and the solid arrow represents the injected liquid. (f) Hollow triangle refers to muscle fascia. (g) Muscle fascia stretched out by itself when touched by the needle tip. (h) Needle tip pierced into the muscle fascia. (i) Muscle fascia was stripped by the liquid knife, and the solid arrow represents area in the muscle fascia with liquid injected.
