Article Abstract

Background: Myofascial pain syndrome (MPS) is a common musculoskeletal disease associated with myofascial trigger point (MTrP). Muscle injury is one of the common causes of MPS. Currently, there is no effective treatment for MPS.

Case Summary: A 24-year-old female with chronic lower back MPS secondary to quadratus lumborum (QL) injury underwent comprehensive evaluation using validated scales: Pain severity (visual analog scale, McGill Pain Questionnaire), functional disability (Oswestry Disability Index, Roland Morris Disability Questionnaire), and quality of life [short form 36 (SF-36)]. Objective assessments included sEMG of bilateral QL muscles, Myoton mechanical property analysis, and magnetic resonance imaging volumetric measurements. The patient received four ultrasound-guided platelet-rich plasma (PRP) injections at 4-week intervals, with follow-up evaluations conducted at 1, 3, and 6 months post-treatment.

Conclusion: Ultrasound-guided PRP injections alleviated pain, restored function, and improved quality of life in post-traumatic MPS. sEMG demonstrated neuromuscular symmetry restoration in MTrP-affected muscles, supporting the therapeutic potential of PRP.

Objective: To evaluate the short-term tendon healing response to a single ultrasound-guided autologous platelet-rich plasma (PRP) injection in patients aged 25-60 years with clinically and ultrasonographically confirmed unilateral, partial- to full-thickness rotator cuff tears.

Materials And Methods: This descriptive case series was conducted at the Department of Orthopedic and Spine Surgery, Ghurki Trust Teaching Hospital, Lahore, from April 25 to October 24, 2018. A total of 90 patients aged 25 to 60 years, with clinically and ultrasonographically confirmed partial- and full-thickness rotator cuff tears, were enrolled.

Background: Carpal tunnel syndrome (CTS) is the most common focal mononeuropathy caused by the compression of the median nerve within the carpal tunnel. Ultrasound-guided hydrodissection with corticosteroids, platelet-rich plasma injection, and median nerve pulsed radiofrequency are all potential treatments for relieving symptoms of CTS in mild and moderate cases, comparison between their clinical outcomes is yet to be studied.The primary outcome was pain measured by Visual Analog Scale (VAS).

Ultrasound-Guided Nerve Hydrodissection for Peripheral Entrapment Neuropathies.

Muscle Nerve

Department of Physical Medicine and Rehabilitation, Virginia Commonwealth University, Richmond, Virginia, USA.

Ultrasound-guided nerve hydrodissection is a technique whereby fluid is used to separate a nerve from surrounding tissue as a means to alleviate symptoms of peripheral entrapment neuropathies. Pre-procedure scans are necessary to plan a safe procedure. Typically, the operator will target the site of nerve entrapment, which is just distal to the point of maximum cross-sectional area enlargement.

Hypothesis And Background: Manipulation under anesthesia (MUA), combined with ultrasound-guided platelet-rich plasma injection, is expected to yield favorable functional outcomes in cases of shoulder stiffness concomitant with rotator cuff injury (RCI). Little has been reported on the efficacy of MUA with ultrasound-guided platelet-rich plasma injection for shoulder stiffness concomitant with RCI.

Methods: Beginning from August 2023, 30 patients with shoulder stiffness accompanied by RCI were enrolled in the study.
