“…Ultrasonography further assesses vascular structures and areas of hyperemia seen in active inflammation (9). Since ultrasound-guided injections have proven to be more accurate than blind injections (13,14), they also minimize inadvertent damage to surrounding tissues. Improvements in clinical outcomes have also been demonstrated when using ultrasound guidance versus blind injections of corticosteroids (7).…”

Background Intra-articular injections have diagnostic and therapeutic roles in foot and ankle pathologies due to complex anatomy, small size, diverse bones, and joints with proximity in this region. Conventionally, these injections are carried out using anatomical landmark technique and/or fluoroscopic guidance. The small joint space and needle size make the injection challenging. Fluoroscopy is not readily available in the clinical setting; ultrasound-guidance for injections is therefore increasingly being used. We compared the accuracy of intra-articular talonavicular injections using the anatomical landmark technique versus the ultrasound-guided method. Purpose To determine whether ultrasound guidance yields superior results in intra-articular injections of the talonavicular joint compared to injections using palpatory method guided by anatomical landmarks. Material and Methods The feet of 10 cadaveric specimens were held in neutral position by an assistant while a fellowship-trained foot-ankle orthopedic surgeon injected 2 cc of radiopaque dye using anatomical landmarks and palpation method in five specimens and under ultrasound guidance in the remaining five. The needles were left in situ in all specimens and their placement was confirmed fluoroscopically. Results In all five specimens injected under ultrasound guidance, the needle was found to be in the joint, whereas all five injected by palpation only were out of the joint, with one in the naviculo-cuneiform joint, showing ultrasound guidance to significantly increase the accuracy of intra-articular injections in the talonavicular joint than palpatory method alone. Conclusion Ultrasound-guided injections not only confirm correct needle placement, but also delineate any tendon and/or joint pathology simultaneously.

Ultrasound-guided treatments for chronic Achilles tendinopathy: an update and current status

et al. 2010

Minimally-invasive treatments for chronic Achilles tendinopathy may prevent the need for surgery when conservative methods have failed. Whilst injections have traditionally been used to manage symptoms, recently described therapies may also have disease-modifying potential. Ultrasound provides the ability to guide therapeutic interventions, ensuring that treatment is delivered to the exact site of pathology. Treatments can be broadly categorised according to their intended therapeutic targets, although some may act through several possible mechanisms. In this article, we review the ultrasound-guided techniques currently used to treat chronic Achilles tendinopathy, with reference to the available literature. There is strong pilot-level evidence supporting the use of many of these techniques, although large definitive trials are lacking. An approach towards the management of chronic Achilles tendinopathy is suggested.
