Ultrasound-guided musculoskeletal interventional procedures around the shoulder

[Research progress of ultrasound in diagnosis and treatment of shoulder joint diseases]

Objective

To review the research progress of ultrasound in the diagnosis and treatment of shoulder diseases, in order to provide a theoretical basis for the further development of ultrasound in shoulder surgery.

Methods

The recent literature on the application of ultrasound in the shoulder joint was extensively reviewed. The application of ultrasound in the diagnosis and treatment of shoulder joint diseases, and the advantages and disadvantages of ultrasound were analysed, and the development trend of ultrasound technology in the shoulder joint area was prospected.

Results

At present, the diagnosis of shoulder joint diseases mainly relies on MRI, however, with the development of ultrasound technology, ultrasound with the characteristics of convenient, reliable, and real-time dynamic evaluation is more and more recognized in the diagnosis process of shoulder joint diseases, combined with three-dimensional ultrasound, ultrasound intervention, and elastography can improve the accuracy, sensitivity, and specificity of the diagnosis, and is suitable for the diagnosis and treatment of various shoulder joint diseases, which is expected to carry out early prevention of shoulder joint diseases in the future and achieve more refined and minimally invasive treatment.

Conclusion

Ultrasound technology has wide application prospect in shoulder joint diseases, but it is still in the developing stage, and the subjective dependence needs to be solved further.

US-guided percutaneous irrigation of extra-shoulder calcific tendinitis

OBJECTIVES

To investigate the efficacy and safety of ultrasound-guided percutaneous irrigation of calcific tendinopathy (US-PICT) applied out of the shoulder, comparing its effectiveness to US-PICT of the rotator cuff.

METHODS

Patients subjected to US-PICT for extra-shoulder calcific tendinitis (Case Group) were compared to those subjected to US-PICT of the rotator cuff (Control Group). We had pre-procedure Visual Analogue Scale (VAS) pain score, 1- and 3-month VAS of patients of the Case Group, pre-procedure and 3-month VAS of patients of the Control Group.

RESULTS

The Case Group consisted of 41 patients (27 women; mean age: 45 ± 9years): 26 gluteus medius, 5 patellar tendon, 3 rectus femoris, 2 gluteus maximus, 2 common extensor tendon, 1 extensor carpi radialis longus, 1 pes anserinus, and 1 peroneus longus. The Control Group included 41 patients (27 women; mean age: 47 ± 11 years). The mean pre-procedure VAS of the Case Group was 8.8 ± 0.7 with a significant (P < .001) drop at 1 month (4.5 ± 0.6) and 3 months (3.6 ± 0.6). The mean pre-procedure VAS of the Control Group was 8 ± 1.4 and dropped to 3.1 ± 1.6 after 3 months (P < .001). Post-treatment VAS at 3 months was not significantly different between two Groups (P = 0.134). Similarly, the decrease of VAS from baseline to 3 months was not significantly different between the two Groups (P = 0.264).

CONCLUSIONS

US-PICT is a safe and effective procedure that can be used out of the shoulder.

ADVANCES IN KNOWLEDGE

This study demonstrated the safety and effectiveness of US-PICT as a valuable therapeutic option for extra-shoulder calcific tendinitis, with similar clinical outcome to the same procedure performed in the rotator cuff. The technique must be adapted in some deeply located calcifications by means of the use of different needles and by thoroughly planning the access point for the procedure.

Ultrasound-guided Musculoskeletal Interventional Procedures Around the Hip: A Practical Guide

Several studies have shown that ultrasound guidance may contribute to improved safety, effectiveness and accuracy of musculoskeletal interventional procedures performed around the hip if compared to those performed with a landmark-guided technique. Different approaches and injectates can be used for treating hip musculoskeletal disorders. These procedures may involve injections in the hip joint, periarticular bursae, tendons, and peripheral nerves. Intra-articular hip injections are mostly used as a conservative approach for treating patients affected by hip osteoarthritis. Ultrasound-guided injection of the iliopsoas bursa is performed in patients with bursitis and/or tendinopathy, to treat those with painful prosthesis due to iliopsoas impingement, or when the lidocaine test is indicated to identify the iliopsoas as a source of pain. Ultrasound-guided interventions are routinely used in patients with greater trochanteric pain syndrome having as target the gluteus medius/minimus tendons and/or the trochanteric bursae. Ultrasound-guided fenestration and platelet-rich plasma injection are applied in patients with hamstring tendinopathy with good clinical outcomes. Last but not least, ultrasound-guided perineural injections can be used for peripheral neuropathies or blocks of the sciatic, lateral femoral cutaneous, and pudendal nerves. In this paper, we discuss the evidence and technical tips for musculoskeletal interventional procedures performed around the hip, highlighting the added value of ultrasound as an imaging guidance modality.
