Background: Adhesive capsulitis (AC), more commonly known as "frozen shoulder", is a painful shoulder condition. The illness progresses through three phases: freezing, frozen and thawing. A gold standard treatment for adhesive capsulitis is not defined. The goal of any treatment is to reduce pain and restore shoulder movement., Objective: Objective of the present study is to evaluate the efficacy of gleno-humeral hydrodistension associated with physical therapy in patients with diagnosed adhesive capsulitis comparing the outcomes in term of pain and range of motion in patients with a phase 1 and a phase 2 disease., Method: Between January 2022 and April 2023, We evaluated 87 patients with adhesive capsulitis, 47 were excluded for others concomitant pathologies, finally 40 patients were enrolled for the study, of whom 23 had capsulitis in stage 1 and 17 in stage 2. Patients were evaluated at baseline and at 2, 4 and 6 months after infiltration recording range of motion in all planes, pain and functionality scores., Results: A significant improvement was recorded in shoulder range of motion in all planes with the except of extension in both groups. Phase 2 patients were able to regain shoulder range of motion in all planes except internal rotation which was recovered with more difficulty. Pain and functionality scores improved significantly between baseline and follow-up visits., Conclusion: Ultrasound-assisted hydrodistention of the glenohumeral joint combined with targeted exercise has been successful in improving pain relief, reducing disability, and increasing range of motion in subjects with stage 1 and 2 adhesive capsulitis, especially if diagnosed before phase 2 (when the range of motion is completely reduced)., (© 2024.

Frozen shoulder is a common and self-limiting condition affecting the soft tissues of the shoulders, characterized by severe pain, impaired range of motion (ROM) and limitation of daily activities. Its prevalence is 5% and it occurs most commonly in the fifth and sixth decades of life; women are more affected [DePalma in Clin Orthop Relat Res 466:552-560, 2008]. It can be idiopathic or associated with other conditions such as metabolic disorders, diabetes, thyroid diseases, prolonged immobilization, trauma [DePalma in Clin Orthop Relat Res 466:552-560, 2008], or complications after vaccine administration known as SIRVA (Shoulder injury related to vaccine administration). SIRVA is not caused by the vaccine itself but by inappropriate vaccination techniques [Martín Arias et al. in Vaccine 35:4870-4876, 2017]. The natural history of the frozen shoulder is a progression through three stages based on clinical and arthroscopic presentations: freezing, frozen and thawing [DePalma in Clin Orthop Relat Res 466:552-560, 2008; Do et al. in Orthop J Sport Med 9:232596712110036, 2021]. The onset is characterized by disabling pain, that worsens at night; it is induced by inflammation and hypervascularity and lasts from 10 to 36 weeks [Do et al. in Orthop J Sport Med 9:232596712110036, 2021]. The second stage is predominated by stiffness and severe reduction of ROM. This phase typically lasts from 9 to 12 months [Do et al. in Orthop J Sport Med 9:232596712110036, 2021]. Eventually, a recovery phase occurs, with a gradual recovery of the ROM that can last between 12 and 42 months. Ultrasound is an emerging diagnostic tool that contributes to differential diagnosis and treatment [Zappia et al. in Insights Imaging 7:365-371, 2016; Ricci et al. in J Ultrasound Med 39:633-635, 2020]: signs of adhesive capsulitis consist of thickening of the inferior recess of the glenohumeral joint capsule, thickening of the coracohumeral ligament and soft tissue structures in the rotator cuff interval, with hypervascularity. An unspecific sign is increased fluid in the tendon sheath of the long head of the biceps [Martín Arias et al. in Vaccine 35:4870-4876, 2017; Tandon et al. in J Ultrasound 20:227-236, 2017]., (© 2023.

Foot pain is common in daily clinical practice but thrombosis of the foot veins is rarely considered as a differential diagnosis. Several cases of plantar veins thrombosis are reported in literature but a detailed description of ultrasonographic findings in case of thrombosis of the dorsal venous arch of the foot is lacking. We report a case of ours with a thrombosis of the medial marginal vein and dorsal venous arch of the foot, showing its close anatomical relation with the extensor hallucis longus tendon., (© 2020.

Syndesmotic injuries, also referred as high ankle sprains, may cause significant ankle instability and chronic pain. Ultrasound (US) is a well-proven imaging modality to evaluate the ligaments of the ankle, due to its high spatial resolution and the possibility to perform dynamic examinations. However, considering the syndesmosis complex, the sonographic appearance of the posterior inferior tibiofibular ligament (PITFL) is not well described in the pertinent literature and, to the best of our knowledge, we found no report of PITFL avulsion demonstrated at US, as in the case presented.

Medial knee pain is common in clinical practice and can be caused by various conditions. In rare cases, it can even be by calcific bursitis of the medial collateral ligament (MCL). Treatment of calcific bursitis and/or calcification of the MCL classically includes observation, local injections, shockwave therapy and surgical resection. We report a case of nontraumatic medial knee pain poorly responsive to conservative treatments. Ultrasound (US) imaging revealed a massive lobed hyperechoic formation with partial acoustic shadow in the MCL context compatible with calcific bursitis, and magnetic resonance imaging (MRI) confirmed the presence of the bursa's calcific deposit surrounded by hyperintense signal compatible with pericalcific edema. We performed a double-needle ultrasound-guided percutaneous lavage (UGPL), which is today a fairly common treatment for many musculoskeletal disorders, such as rotator cuff calcific tendinopathy and elbow extensor tendons pathology, but regarding the knee, it is not part of ordinary care. This report shows the clinical and imaging presentation of calcific bursitis of the MCL and describes in detail the technique to perform the UGPL with a system of two needles, two syringes and a double connection to ensure a correct lavage of the calcium deposit without significant intrabursal pressure increase and consequently without pain during the procedure.

We report the case of a 42-year-old patient referred to our department for the examination of two large, symmetrical inguinal lumps. The ultrasound examination of the swollen lymph node demonstrated a cortical echogenicity greater than the medullary echogenicity, and the vascularization stop around the cortical zone suggested a pathological pattern of mantle cell lymphoma. In this type of lymphoma, lymphocytes are localized in a mantle zone, inducing a thickening of the lumps. Therefore, for the first time, ultrasound examination detected sonographic vascular features of mantle cell lymphoma, allowing the identification of the disease and suggesting the specific histological diagnosis.

Purpose: Cervical pain is very frequent in the general population. In clinical practice, plain X-ray and, in selected cases, computed tomography or magnetic resonance imaging, are performed. However, the feasibility and utility of ultrasound examination have been poorly investigated. Aim of the present study was to evaluate whether ultrasound could be useful in the diagnosis of localized cervical pain., Methods: Subjects suffering from posterior cervical pain without irradiation to surrounding tissues were enrolled. After clinical and functional evaluation (demographic and anthropometric data, VAS at rest and during neck movements, symptoms duration, and characteristics of pain onset [atraumatic or traumatic]), an ultrasound exam of the cervical spine was performed according to standard protocols., Results: The anatomic structures of the neck district were visualized in 124/127 enrolled patients and pathological features were observed in 58. Significant ultrasound differences were registered between the patients with traumatic and atraumatic onset of neck pain. In the first group, articular effusion, capsular bulging, disalignment and avulsion of the articular apex were observed, whereas in the latter cortical irregularities, osteophytosis, and articular ankylosis were prevalent., Conclusions: Ultrasound examination can be used as diagnostic tool in the evaluation of selected patients suffering from localized cervical pain, particularly in cases of pain due to traumatic injuries., Competing Interests: The authors declare no potential conflicts of interests with respect to the authorship and/or publication of this article.
