Ultrasound-guided hip joint injection is a joint injection in the hip, assisted by medical ultrasound. Hip and groin pain often presents a diagnostic and therapeutic challenge. The differential diagnosis is extensive, comprising intra-articular and extra-articular pathology and referred pain from lumbar spine, knee and elsewhere in the pelvis.
The needle size, length and type should be selected based on the site, depth and patient's body habitus. 22–24G needles are sufficed for most injections. [1] As an example, ultrasound-guided hip joint injection [16] can be considered when symptoms persist despite initial treatment options such as activity modification, analgesia and physical ...
Medical ultrasound includes diagnostic techniques (mainly imaging techniques) using ultrasound, as well as therapeutic applications of ultrasound. In diagnosis, it is used to create an image of internal body structures such as tendons, muscles, joints, blood vessels, and internal organs, to measure some characteristics (e.g., distances and velocities) or to generate an informative audible sound.
Ultrasound can ablate tumors or other tissue non-invasively. [4] This is accomplished using a technique known as high intensity focused ultrasound (HIFU), also called focused ultrasound surgery. This procedure uses generally lower frequencies than medical diagnostic ultrasound (250–2000 kHz), but significantly higher time-averaged intensities.
Ultrasound scan (left) and ultrasound-guided injection (right) of the piriformis muscle. Gmax = gluteus maximus; Pm = piriformis muscle; sn = sciatic nerve; S = sacrum; H = hip bone. Injections are part of multi-modal therapy and can be therapeutic.
These techniques are known as Magnetic Resonance guided Focused Ultrasound Surgery (MRgFUS) [31] [32] and Ultrasound guided Focused Ultrasound Surgery (USgFUS) respectively. [ 1 ] [ 33 ] MRgFUS is a 3D imaging technique which features high soft tissue contrast and provides information about temperature, thus allowing to monitor ablation.
Ultrasound-guided hip joint injection: A skin mark is made to mark the optimal point of entry for the needle. [112] Use of analgesia, intra-articular cortisone injection and consideration of hyaluronic acids and platelet-rich plasma are recommended for pain relief in people with knee osteoarthritis. [113]
Most image-guided surgical procedures are minimally invasive. A field of medicine that pioneered and specializes in minimally invasive image-guided surgery is interventional radiology. A hand-held surgical probe is an essential component of any image-guided surgery system as it provides the surgeon with a map of the designated area. [8]
