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 ...
Ultrasound-guided injections are the gold standard for differentiating deep gluteal syndrome from other sources of pain. [9] Diagnostic injections function in a similar way to deep palpation. While palpation causes a signal to be sent along a nerve which patients can localize relative to their pain (the spot hurts or it doesn't), anesthetics ...
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.
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.
The needle is radiographically guided into the glenohumeral joint space, after which the patient is evaluated by fluoroscopy, CT or MRI. The gadolinium in the contrast fluid yields a bright signal on T1 weighted images allowing for better evaluation of the joint capsule, the articular surface of the bones and, in particular, the labral cartilage.
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]
Each innominate bone (ilium) joins the femur (thigh bone) to form the hip joint; thus the sacroiliac joint moves with walking and movement of the torso. [9] In this joint, hyaline cartilage on the sacral side moves against fibrocartilage on the iliac side. The sacroiliac joint contains numerous ridges and depressions that function in stability.
