Efficacy of Ultrasound-Guided Hydrodissection for Treating De Quervain's Tenosynovitis.

Objective: This study evaluated the effectiveness of ultrasound-guided hydrodissection treatment for De Quervain's stenosing tenosynovitis, characterized by the narrowing of the first extensor compartment of the wrist. Notably, approximately 2% of cases involve a fibrous septum that divides the compartment. Subjects and Methods: Ninety-five patients diagnosed with De Quervain's disease using ultrasound underwent hydrodissection treatment. When a septum was present, the needle was redirected into each sub-compartment to distribute the therapeutic solution evenly and facilitate the breaking of the septum. Results: Ninety patients reported significant improvements in pain and functionality within 2 months of the initial treatment, with a marked decrease in the mean visual analog scale score from 7.65 ± 1.31 to 1.65 ± 2.32. A second infiltration, administered 2 months later, further alleviated pain and enhanced hand functionality. However, 5 patients with septum required surgical intervention after nonconclusive results from the infiltrative treatment. Conclusions: This study confirms that ultrasound-guided hydrodissection is an effective treatment for approximately 95% of patients with De Quervain's disease, achieving substantial pain relief and improved joint mobility after the first treatment. These findings support the continued use of ultrasound guidance to enhance the precision and efficacy of treatment in complex cases.

Adhesive capsulitis: the importance of early diagnosis and treatment.

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).

Ultrasound definition of subacromial chronic "fibro-adhesive" bursitis and its treatment via ultrasound guided hydrodilation: a prospective pilot study.

PURPOSE: The shoulder pain is one of the main causes that lead the patient to medical evaluation. Today, the ultrasound (US) represents an essential tool in the orthopaedical, rheumatological and rehabilitative setting to address the musculoskeletal causes of pain. Amongst the commonest causes of shoulder complains lay the frequent subacromial chronic bursitis (SACB). In this condition, the thickening of the bursal walls and subsequent fusion of the two synovial sheets leads to the reciprocal loss of bursal walls gliding under the subacromial space and consequently pain. This condition represents a common cause of shoulder pain and may be easily addressed by musculoskeletal sonographers. The purpose of this paper will be to describe the US appearance of SACB and to evaluate the efficacy of US-guided hydrodilation in its treatment. METHODS: We included patients with painful shoulder attending our outpatient clinic for shoulder complains with the diagnosis of SACB with a bursal wall > 1.5 mm. A group was treated via US-guided hydrodilation, while the control group was treated via a classical blind approach using triamcinolone acetonide. Both groups underwent the same rehabilitation program following the injections. The shoulder functionality was assessed via qDASH questionnaire at baseline, days 3, 7, 14, 30, 60, and 90. A p <0.05 was considered significant. RESULTS: Both groups displayed a significant reduction of pain; nevertheless, in the group treated with US-hydrodilation, there was no need for re-treatment. CONCLUSIONS: The US-guided hydrodilation for SACB should be the preferred technique to detach bursal walls and improve patient symptoms, since it requires fewer invasive maneuvers.

Ultrasound-Guided Infiltrative Treatment Associated with Early Rehabilitation in Adhesive Capsulitis Developed in Post-COVID-19 Syndrome.

Background and Objectives: Post-COVID-19 syndrome is commonly used to describe signs and symptoms that continue or develop after acute COVID-19 for more than 12 weeks. The study aimed to evaluate a treatment strategy in patients with adhesive capsulitis (phase 1) developed in post-COVID-19 syndrome. Materials and Methods: The method used was an interventional pilot study in which 16 vaccinated patients presenting with the clinical and ultrasound features of adhesive capsulitis (phase 1) developed during post-COVID-19 syndrome were treated with infiltrative hydrodistension therapy under ultrasound guidance associated with early rehabilitation treatment. Results: Sixteen patients with post-COVID-19 syndrome treated with ultrasound-guided infiltration and early rehabilitation treatment showed an important improvement in active joint ROM after 10 weeks, especially in shoulder elevation and abduction movements. The VAS mean score before the treatment was 6.9 ± 1.66. After 10 weeks of treatment, the VAS score was 1 ± 0.63. Conclusions: The study demonstrated that the management of adhesive capsulitis (phase 1) developed in post-COVID-19 syndrome, as conducted by physiotherapists in a primary care setting using hydrodistension and a rehabilitation protocol, represented an effective treatment strategy.

Adhesive capsulitis after COVID-19 vaccine injection: a peculiar case treated with combined bursa distention and glenohumeral capsular hydrodilatation.

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].

Ultrasound Features of Adhesive Capsulitis.

INTRODUCTION: Adhesive capsulitis (AC), which is characterised by shoulder pain and a limited range of motion (ROM), is usually diagnosed on the basis of clinical suspicion, with imaging only being used to exclude other causes of similar symptoms. The aim of this study was to identify and describe the typical ultrasound (US) features of AC in a group of patients with shoulder pain and stiffness. METHODS: This was a cross-sectional study of 1486 patients with AC in which two experienced US specialists examined the axillary pouch (AP), the coracohumeral ligament (CHL), the superior glenohumeral ligament (SGHL), and the long head of the biceps tendon (LHBT), and dynamically visualised the infraspinatus tendon during passive external rotation (PER) during a US evaluation of shoulder ROM. RESULTS: AC was confirmed in 106 patients (7.1%). Thickening of the AP of more than 4 mm was observed in 93.4% of the patients, whereas 6.6% showed AP thickening of less than 4 mm but more than 60% of the thickening in the contralateral shoulder. Effusion within the LHBT sheath was detected in 71% of the patients, and thickening of the CHL or SGHL in 88%. The dynamic study of the infraspinatus tendon showed reduced sliding with folding towards the joint capsule in 73% of cases, thus changing the tendon's profile from flat to concave during PER. The reduced tendon sliding was associated with a bouncing movement that returned the tendon to its baseline resting position in 41.5% of cases. CONCLUSIONS: We believe a sufficiently experienced US specialist can confirm a clinical diagnosis of AC by carrying out a comparative study of APs, evaluating the thickness of the CHL and SGHL, and detecting reduced sliding of the infraspinatus tendon.

Sonographic visibility of the main posterior ankle ligaments and para-ligamentous structures in 15 healthy subjects.

The present article describes the ultrasound (US) appearance of ligaments and paraligamentous structures which are not included in standard US imaging of the ankle: the posterior inferior tibiofibular ligament (PITFL), the transverse tibiofibular ligament (TTFL), the posterior talofibular ligament (PTFL), the posterior intermalleolar ligament (PIL), the synovial recess (SR) of the posterior joint and the os trigonum (OT). Two skilled operators examined 15 ankles in 15 healthy volunteers. Correlation between thickness of the main ligaments and body mass index (BMI) was also analyzed. Compound and tissue harmonic imaging (THI) were carried out using 12-, 6-15- and 9-MHz linear probes. Exploration of the posterior ankle ligament complex is accurately described including correct ankle position, echogenicity, shape, direction and thickness. Both operators identified and measured the main ligaments (PITFL, TTFL and PTFL) in all volunteers (Intraclass Correlation Coefficient ranged from 0.8 to 1); both operators also detected SR and OT in 2/15 ankles and posterior intermalleolar ligament (PIL) in 5/15 ankles. Pearson's test showed a significant correlation (< 0.05) between TTFL thickness and BMI. Also, a dynamic study was carried out showing tension of the PTFL during dorsiflexion in 7/15 subjects. Our results highlight the potential role of accurate US imaging in detecting posterior ankle ligament involvement in acute and chronic traumas. To our knowledge, there are no previous articles in the literature dealing with this topic providing an accurate description of the US procedure, and in particular, no study has been carried out to identify OT.

Sonographic diagnosis of clinically unsuspected thrombosis of the medial marginal vein and dorsal arch of the foot.

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.

High ankle sprain: sonographic demonstration of a posterior inferior tibiofibular ligament avulsion.

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.

Ultrasound-Guided Treatment of Extrusive Medial Meniscopathy: A 3-Step Protocol.

Medial knee pain is commonplace in clinical practice and can be related to several pathologic conditions: ie, medial plica syndrome, saphenous nerve entrapment, pes anserine syndrome, medial collateral ligament injury, and medial meniscus disorders. Ultrasound (US) imaging represents a valuable first-line diagnostic approach to adequately visualize the superficial structures in the medial compartment of the knee to easily plan for prompt treatment. Currently, the management of chronic degenerative diseases involving the menisci, and causing their extrusion, consists of surgery (arthroscopic partial meniscectomy). This procedure often allows only a partial resolution of pain and functional impairment. In the pertinent literature, US-guided interventions for the medial meniscus are proposed, mainly to decrease pain and inflammation or to induce regeneration. Likewise, this Technical Innovation describes in detail the US findings of medial extrusive meniscopathy and also illustrates a novel US-guided technique to treat the bursa of the medial collateral ligament, the extruded fragment of the medial meniscus, and the synovial parameniscal recesses simultaneously.

Treatment of a calcific bursitis of the medial collateral ligament: a rare cause of painful knee.

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.

Localized cervical pain: advantages and limits of ultrasound evaluation.

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.

Intramuscular migration of calcific tendinopathy in the rotator cuff: ultrasound appearance and a review of the literature.

Calcific tendinopathy of the shoulder is a common condition caused by calcium hydroxyapatite crystals, affecting the tendons of the rotator cuff. Among uncommon complication, one is the migration of the calcium in the subacromion-subdeltoid bursa. More rare is the intraosseous migration. We present four cases of an even more rare condition, not well described in literature yet, the intramuscular migration of calcium.

Muscle Injuries: A Brief Guide to Classification and Management.

Muscle injuries are frequent in athletes. Despite their high incidence, advances in clinical diagnostic criteria and imaging, their optimal management and rehabilitation strategies are still debated in literature. Furthermore, reinjury rate is high after a muscle lesion, and an improper treatment or an early return to sports can increase the rate of reinjury and complications. Most muscle injuries are managed conservatively with excellent results, and surgery is normally advocated only for larger tears. This article reviews the current literature to provide physicians and rehabilitation specialists with the necessary basic tools to diagnose, classify and to treat muscle injuries. Based on anatomy, biomechanics, and imaging features of muscle injury, the use of a recently reported new classification system is also advocated.

Sonoelastography in the diagnosis of tendinopathies: an added value.

BACKGROUND: sonoelastography helps in the detection of abnormalities not yet evident on B-mode exam. METHODS: in this observational study, we report a collection of cases of symptomatic patients without alterations at ultrasound imaging but with evidence of pathological findings at sonoelastography. Patients, with clinical history suggestive for tendinopathies or surgically treated, and negative at the ultrasound exam, were submitted to sonoelastography. Out of 846, 632 patients with positive ultrasound exam were excluded. Sonoelastography was therefore performed in the remaining 214. RESULTS: the examination was positive in 168 cases: 78 patients were affected with shoulder diseases, while elbow pathology was observed in 31 subjects; patellar, Achilles and plantar fascia disorders were reported in 19, 27, and 13 patients, respectively. CONCLUSION: sonoelastography can reveal tendon abnormalities of clinical relevance in a high percentage of cases, where the ultrasound exam was negative, making the method a complementary tool to ultrasound evaluation.

Common peroneal nerve palsy due to hematoma at the fibular neck.

Common peroneal nerve palsy is an infrequent pathology mostly related to endogenous or exogenous compression. The exogenous compression is frequently related to trauma: knee fractures or hematoma arisen after a direct blow. Fractures may cause a direct lesion of the nerve; hematoma causes a compression of the nerve at the fibular neck causing pain and functional loss. Lesions of the common peroneal nerve can also be related to total knee arthroplasty. The clinical evaluation is characterized by muscle weakness with or without sensory abnormality. The etiopathogeneses of the compression have to be confirmed by ultrasound or magnetic resonance imaging before the surgical treatment. The purpose of this article is to describe a case of common peroneal nerve palsy due to a posttraumatic hematoma after a sport-related injury. We evaluated this case with dynamic ultrasound with good visualization of the morphology of the lesion and of the compression.

Ultrasonographic predictors for the development of joint damage in rheumatoid arthritis patients: a single joint prospective study.

OBJECTIVES: This paper aims to evaluate if any ultrasonographic aspect of metacarpo-phalangeal (MCP) joint can be predictors for the development of new joint damage, at single joint level, in rheumatoid arthritis (RA) patients. METHODS: Two hundred and forty MCP joints of 24 patients with RA were prospectively evaluated both clinically and by ultrasound (US) at time 0, at six months and 12 months, in order to collect the following variables: presence of synovial hypertrophy and power-Doppler (PD) vascularisation both graded on a semiquantitative (0-3) scale, and the number and dimension of bone erosions. X-ray examinations were carried out at time 0 and at 12 months and lesions were graded using the Sharp/van der Heijde (S/vdH) method at single joint level. Potential prognostic determinants for joint damage obtained at the first examination and during follow-up were entered in a conditional logistic regression analysis. RESULTS: Fifteen out of seventeen (88%) of the new eroded joints on x-rays examination had persistent PD vascularity and 14/17 (82%) had persistent synovial thickening (p=0.001 and p=0.02, vs. non-eroded joints, respectively). In multiple conditional logistic regression analysis, the most important factor associated with the development of radiological joint damage was the presence of a synovial PD score ≥2 on two or more US evaluations (OR 8.51 [95%CI 1.84-39.48] for Rx new erosions and OR 8.30 [95%CI 1.97-38.9] for increased S/vdH local joint score). Both baseline synovial score ≥2 and presence of Rx erosions were also significantly associated with the development of radiological joint damage. Two predictive models for x-ray erosions and total single joint level S/vdH damage score were constructed consisting of 2 baseline plus one longitudinal variable with a ROC AUC of 0.916 (95%CI 0.867-0.965) and 0.886 (95%CI 0.814-0.957). CONCLUSIONS: At the single joint level, the presence of US determined synovial thickness and PD signal at baseline and the persistent PD signal over time have relevant prognostic value for the development of articular damage in the same MCP joints of RA patients.
