A positioning approach to upper extremity sonographic evaluation and intervention.

September 2024
Total supported abduction, or TSA, is a position for ultrasound evaluations and guided interventions of the upper extremity. It provides optimal access to the medial arm through the volar wrist and palmar hand for diagnostic evaluations of the median and ulnar nerves as well as procedures including injections for carpal tunnel syndrome, ulnar neuropathy at the elbow, and stenosing tenosynovitis. It enables ease of both ipsilateral and bilateral evaluations/interventions without the need for significant positional changes by the patient or physician.

- This study aimed to compare discomfort levels in three different positions for ultrasound-guided carpal tunnel injections (USCTI) to enhance tolerability for patients with carpal tunnel syndrome (CTS).
- 30 Veterans were evaluated using three positions: Hypersupination, Airplane, and Total Supported Abduction (TSA), with participants rating their pain and ease of holding each position.
- Results showed that Hypersupination was the most painful and least preferred position, while Airplane and TSA were not significantly different in terms of discomfort, suggesting they may be better options for patient comfort during the procedure.
Introduction: Femoral head collapse (FHC) is a rarely reported complication of hip intra-articular corticosteroid injection (IACSI). Upon observing a high rate of FHC after hip IACSI, we sought to (1) describe how we addressed the problem through a systematic evaluation of clinical data and institutional care practices followed by process improvement efforts; and (2) report our results.
Methods: Patients receiving hip IACSI during a 27-month period underwent retrospective review to determine the rate of FHC and to identify associated patient factors or practice shortfalls.
