The effectiveness of percutaneous ultrasound-guided needle tenotomy compared to alternative treatments for chronic tendinopathy: a systematic review

Iliotibial Band Origin Tendinopathy Is an Underrecognized Cause of Anterolateral Hip Pain: A Narrative Review and Clinical Commentary

ABSTRACT

Hip pain is a common concern among athletes. With gluteal tendinopathy, femoroacetabular impingement, and osteoarthritis predominating sports medicine and musculoskeletal practices, less common etiologies may be overlooked. Complex pelvic anatomy and variable pain referral patterns may make identifying an accurate diagnosis challenging. Employing a systematic approach to evaluation and having a thorough understanding of hip region anatomy are essential. A potentially overlooked cause of anterolateral hip pain is iliotibial band origin tendinopathy. Patients often present with pain around the anterolateral hip and tenderness to palpation at the anterolateral iliac crest. While patients with iliotibial band origin tendinopathy usually respond to nonsurgical intervention, there is little literature to guide evaluation and treatment, highlighting a gap in the recognition of this condition. The purpose of this narrative review is to describe the anatomy of the proximal iliotibial band origin, outline the clinical diagnosis and imaging findings of ITBOT, and summarize current treatment options.

Percutaneous Interventions for Injuries in Athletes: Implications on Return to Play

For nonsurgical musculoskeletal (MSK) injuries in athletes, image-guided percutaneous intervention may aid in recovery and decrease return to play (RTP) time. These interventions fall into two major categories: to reduce inflammation (and therefore alleviate pain) or to promote healing. This review describes the risks and benefits of the various percutaneous interventions in MSK athletic injury and surveys the literature regarding the implication of these interventions on RTP.

The Effects of Ultrasound-Guided Percutaneous Tenotomy on Patients' Pain and Satisfaction Levels

INTRODUCTION

Tendinopathy is a common pathology with numerous treatment options. Ultrasound-guided percutaneous tenotomy is a newer procedure to treat chronic tendinopathy. It reduces costs and risks compared to other treatments, such as open surgery and platelet-rich plasma (PRP) injections. The goal of percutaneous tenotomy is to induce an acute inflammatory response that recruits clotting and growth factors, induces bleeding, and transforms scar tissue and diseased tendons into a healing state.

METHODS

A tenotomy was performed in 57 patients for elbow epicondylitis (13), supraspinatus tendonitis (4), gluteal tendinopathy (34), and patellar tendinopathy (5). The survey was created and sent electronically to all 57 patients, yielding 46 respondents. Each patient was surveyed postoperatively to determine their pain levels on a numeric scale from 1 to 10 prior to and following the procedure. We also asked patients about their satisfaction with the procedure, whether they would recommend it to a friend, and how long it took them to recover completely.

RESULTS

Forty-six of 57 patients responded to the survey. The average healing time was 58 days, and no patients required further surgery. Pain scores significantly improved after tenotomies in the shoulder, elbow, and hip. About 74% of patients were completely satisfied with the procedure, and 80% received enough benefit to recommend it to a friend.

CONCLUSIONS

Ultrasonic tenotomy provides significant relief for tendinopathy in the shoulder, elbow, and hip for the majority of patients. The knee pain scores were not significantly reduced, likely due to the small sample size of four patients. Some patients did not experience complete relief and benefited from a PRP injection after tenotomy. Some patients did not benefit, likely due to additional pathology, arthritis, and referred pain. Some limitations to our study include the lack of a control group and each procedure was performed by the same physician, which limits its generalizability. The survey responses were subjective, and the sample size was variable between each body region. More high-quality research is needed to establish the efficacy of tenotomy between different tendons and compare it to other treatment methods.

Incidence and Risk Factors of Systemic Adverse Effects and Complications of Ultrasound- and Fluoroscopy-Guided Glucocorticoid Injections: A Retrospective Cohort Study

OBJECTIVES

The aims of the study are to assess the incidence of systemic adverse effects and complications of ultrasound-guided and fluoroscopy-guided glucocorticoid injections and to identify associated risk factors.

DESIGN

This retrospective cohort study compared participants who received a glucocorticoid injection at the outpatient clinic and participants who had an appointment but did not receive a glucocorticoid injection. Participants were called to verify whether they had experienced any of the predetermined systemic adverse effects and complications. Multiple binary logistic regression was used to identify systemic adverse effect and complication risk factors.

RESULTS

There were 1010 participants in the glucocorticoid injection group and 328 in the nonglucocorticoid injection group. There was no statistically significant difference in the occurrence of systemic infection and decompensated heart failure between the two groups. More participants in the glucocorticoid injection group developed abnormal uterine bleeding and erectile dysfunction, but the differences did not reach statistical significance. Female participants were 1.9 times more likely to develop systemic adverse effects ( P < 0.001). Younger age ( P < 0.001), diabetes ( P = 0.012), and higher glucocorticoid injection doses ( P = 0.024) were also associated with an increased risk of developing systemic adverse effects.

CONCLUSIONS

Identified risk factors for developing glucocorticoid injection systemic adverse effects were younger age, female sex, diabetes, tobacco use, and high glucocorticoid injection doses.

Neurovascular structures to avoid during musculoskeletal ultrasound-guided intervention in the extremities

Ultrasound is a useful modality for guiding injections and other procedures in the extremities. Its portability and the ability to adjust the probe and needle in real time, as well as lack of radiation exposure make it preferable for many routine procedures. However, ultrasound is highly operator dependent and a firm understanding of regional anatomy is important, including neurovascular structures that are in close proximity during many of these procedures. Knowledge of the characteristic location and appearance of neurovascular structures in the extremities allows safe needle advancement and prevention of iatrogenic complications.
