To determine the distribution of sonographically guided deep plantar fascia injections in an unembalmed cadaveric model. ⋯ Sonographically guided deep plantar fascia injections reliably deliver latex deep to the plantar fascia while avoiding intrafascial injection. However, the extent of direct plantar fascia contact is variable due to the intervening FDB. On the contrary, the traversing FBLPN is reliably covered by the injection. Deep plantar fascia injections may have a role in the management of refractory plantar fasciitis, particularly following failed superficial perifascial or intrafascial injections, in cases of preferential deep plantar fascia involvement, or when entrapment/irritation of the distal FBLPN is suspected.

Many ultrasound educational products and ultrasound researchers present diagnostic and interventional ultrasound information using picture-in-picture videos, which simultaneously show the ultrasound image and transducer and patient positions. Traditional techniques for creating picture-in-picture videos are expensive, nonportable, or time-consuming. This article describes an inexpensive, simple, and portable way of creating picture-in-picture ultrasound videos. ⋯ Simultaneously, a webcam captures a live video feed of the transducer and patient position and live audio. Both sources are streamed onto the computer screen and recorded by screen capture software. This technique makes the process of recording picture-in-picture ultrasound videos more accessible for ultrasound educators and researchers for use in their presentations or publications.

Plantar hindfoot and midfoot pain is a common orthopedic condition. Plantar fasciopathy is the most common cause of plantar foot pain, and sonographic evaluation can easily show the characteristic pathologic changes. In addition, sonography is well suited to evaluate other potential causes of plantar foot pain. We present a review of the sonographic findings of plantar fasciopathy and other potential causes of plantar hindfoot and midfoot pain.

Unlike the preoperative findings in patients with papillary thyroid carcinoma, the postoperative sonographic features of cervical lymph nodes have not been established. This study aimed to assess the sonographic features of metastatic lymph nodes after thyroidectomy for papillary thyroid carcinoma. ⋯ The sonographic features of metastatic cervical lymph nodes in postoperative patients with papillary thyroid carcinoma were similar to those in preoperative patients.
