Imaging findings of acute calcific periarthritis, with emphasis on magnetic resonance imaging: pictorial essay.

Acute calcific periarthritis (ACP) is defined as periarticular inflammation associated with intra-articular deposits of hydroxyapatite and other basic calcium phosphate crystals. Patients with ACP present with a sudden onset of pain, together with localized swelling, as well as erythema, tenderness, and reduced range of motion. Familiarity with the clinical and radiological manifestations of ACP aids in the diagnosis and helps differentiate it from other conditions, particularly infectious or inflammatory pathologies such as septic arthritis and gout, thereby reducing the number of unnecessary diagnostic and therapeutic procedures. The objective of this pictorial essay is to illustrate the imaging findings of ACP in various joints, with an emphasis on the findings obtained by magnetic resonance imaging.

A periartrite cálcica aguda (PCA) é uma inflamação periarticular aguda associada a depósitos justa-articulares de hidroxiapatita e outros cristais básicos de fosfato de cálcio. Os pacientes apresentam início súbito de dor, edema localizado, eritema, sensibilidade e redução da amplitude de movimentos. A familiaridade com as manifestações clínicas e radiológicas da PCA facilita o diagnóstico e permite diferenciá-la de outras entidades, em particular, com doenças infecciosas ou inflamatórias, como artrite séptica e gota, reduzindo procedimentos diagnósticos e terapêuticos desnecessários. O objetivo deste ensaio iconográfico é ilustrar os achados de imagem de PCA em algumas articulações, com ênfase na ressonância magnética.

An Unusual Case of Calcific Periarthritis Causing Carpal Tunnel Syndrome and Its Management with Ultrasound-Guided Barbotage.

Hydroxyapatite crystal deposition disease (HADD) is a common disorder resulting from the deposition of calcium hydroxyapatite crystals in various soft tissues, typically in periarticular distribution, including tendons, tendon sheaths, joint capsules, ligaments, bursae, periarticular soft tissues, and occasionally within the joints. The more commonly known subtypes of HADD are calcific tendinopathy and calcific periarthritis. Carpal tunnel syndrome (CTS) can be rarely caused by calcific deposits within the carpal tunnel in the setting of HADD-related calcific periarthritis. Imaging, particularly ultrasound and radiographs, is crucial in distinguishing this entity from the conventional form of CTS that tends to be idiopathic. We describe a rare presentation of CTS secondary to calcific periarthritis in a 45-year-old patient, with imaging demonstrating mass-like calcification within the carpal tunnel, with typical features of those seen with HADD. The patient was treated with ultrasound-guided barbotage, with significant clinical improvement. The case highlights a lesser-known cause of CTS as well as a presentation of HADD, and the role of ultrasound-guided barbotage, a minimally invasive procedure, as a viable first-line management option as an alternative to surgery.

Development of a musculoskeletal shoulder model considering anatomic joint structures and soft-tissue deformation for dynamic simulation.

The shoulder joint has a high degree of freedom and an extremely complex and unstable kinematic mechanism. Coordinated contraction of the rotator cuff muscles that stop around the humeral head and the deltoid muscles and the extensibility of soft tissues, such as the joint capsule, labrum, and ligaments, contribute to shoulder-joint stability. Understanding the mechanics of shoulder-joint movement, including soft-tissue characteristics, is important for disease prevention and the development of a device for disease treatment. This study aimed to create a musculoskeletal shoulder model to represent the realistic behavior of joint movement and soft-tissue deformation as a dynamic simulation using a rigid-body model for bones and a soft-body model for soft tissues via a spring-damper-mass system. To reproduce the muscle-contraction properties of organisms, we used a muscle-expansion representation and Hill's mechanical muscle model. Shoulder motion, including the movement of the center of rotation in joints, was reproduced, and the strain in the joint capsule during dynamic shoulder movement was quantified. Furthermore, we investigated narrowing of the acromiohumeral distance in several situations to induce tissue damage due to rotator cuff impingement at the anterior-subacromial border during shoulder abduction. Given that the model can analyze exercises under disease conditions, such as muscle and tendon injuries and impingement syndrome, the proposed model is expected to help elucidate disease mechanisms and develop treatment guidelines.

Acute calcific periarthritis in a proximal interphalangeal joint of the hand after acute trauma: a rare case.

Acute calcific periarthritis (ACP) in the interphalangeal joints of the hand is rare, with less than 100 cases reported. A rare case of ACP in a proximal interphalangeal (PIP) joint of the hand, in a young black woman, after acute trauma, is presented. She experienced severe pain and limited range of motion, and was medicated with an oral corticoid, which was followed by a rapid resolution of the symptoms. At six months, there were no signs of clinical or radiographic recurrence. Recognition of ACP allows for avoiding unnecessary treatments. In this case, treatment with corticoids might have played a role in a faster recovery.

La periartritis calcificada aguda (PCA) en las articulaciones interfalángicas de la mano es rara, con menos de 100 casos reportados. Se presenta un caso raro de PCA en una articulación interfalángica proximal (IFP) de la mano, en una mujer joven de raza negra, después de un traumatismo agudo. Experimentó dolor intenso y rango de movimiento limitado, y fue medicada con un corticoide oral, lo que fue seguido por una rápida resolución de los síntomas. A los seis meses no hubo signos de recurrencia clínica ni radiológica. El reconocimiento de PCA permite evitar tratamientos innecesarios. En este caso, el tratamiento con corticoides podría haber contribuido a una recuperación más rápida.

Pharmacoacupuncture for the Treatment of Frozen Shoulder: protocol for a systematic review and meta-analysis.

Objectives: Frozen shoulder (FS) is one of the most challenging shoulder disorders for patients and clinicians. Its symptoms mainly include any combination of stiffness, nocturnal pain, and limitation of active and passive glenohumeral joint movement. Conventional treatment options for FS are physical therapy, nonsteroidal anti-inflammatory drugs, injection therapy, and arthroscopic capsular release, but adverse and limited effects continue to present problems. As a result, pharmacoacupuncture (PA) is getting attention as an alternative therapy for patients with FS. PA is a new form of acupuncture treatment in traditional Korean medicine (TKM) that is mainly used for musculoskeletal diseases. It has similarity and specificity compared to corticosteroid injection and hydrodilatation, making it a potential alternative injection therapy for FS. However, no systematic reviews investigating the utilization of PA for FS have been published. Therefore, this review aims to standardize the clinical use of PA for FS and validate its therapeutic effect. Methods: The protocol was registered in Prospero (CRD42023445708) on 18 July 2023. Until Aug. 31, 2023, seven electronic databases will be searched for randomized controlled trials of PA for FS. Authors will be contacted, and manual searches will also be performed. Two reviewers will independently screen and collect data from retrieved articles according to predefined criteria. The primary outcome will be pain intensity, and secondary outcomes will be effective rate, Constant-Murley Score, Shoulder Pain and Disability Index, range of motion, quality of life, and adverse events. Bias and quality of the included trials will be assessed using the Cochrane handbook's risk-of-bias tool for randomized trials. Meta analyses will be conducted using Review Manager V.5.3 software. GRADE will be used to evaluate the level of evidence for each outcome. Results: This systematic review and meta-analysis will be conducted following PRISMA statement. The results will be published in a peer-reviewed journal. Conclusion: This review will provide scientific evidence to support health insurance policy as well as the standardization of PA in clinical practice.

OBJECTIVES: To observe the effects of the local stimulation with 3 acupuncture techniques, i.e. Canggui Tanxue (needle insertion method like dark tortoise detecting point) technique, electroacupuncture (EA) and warm needling (WN) with filiform needles on shoulder pain, shoulder joint function, quality of life, inflammatory indicators and recurrence rate in the patients with chronic scapulohumeral periarthritis (CSP), so as to explore the optimal needling method of acupuncture for the predominant symptoms of CSP during the attack stage in the patients. METHODS: A total of 108 patients with CSP were randomly divided into a manual acupuncture (MA) group (36 cases, one case dropped off), a WN group (36 cases, 3 cases dropped off) and an EA group (36 cases, 1 case dropped off). In the three groups, Jianqian (EX-UE12), Jianyu (LI15), Jianzhen (SI9), Ashi (Extra) and Yanglingquan (GB34) on the affected side were selected. Canggui Tanxue needling technique, WN technique and EA were delivered in the MA group, the WN group and the EA group, respectively, 30 min each time, 3 times weekly for 4 weeks. The Neer test scores were compared；the visual analogue scale (VAS) was used to assess the degree of shoulder joint pain；the daily life activity abilities was evaluated using the activities of daily living (ADL) scale；the serum prostaglandin E2 (PGE2) content was measured using ELISA before and after treatment. The effectiveness rate and recurrence rate were calculated, and the occurrences of adverse reactions were recorded. RESULTS: Compared with the scores before treatment, the scores of pain, joint function, and range of motion as well as the total score of Neer test were all increased after treatment in the three groups (P<0.05)；the VAS score, ADL score and the content of serum PGE2 were decreased (P<0.05). After treatment, the pain score of Neer test in the EA group and the WN group were higher than those of the MA group (P<0.05), the joint function score of Neer test in the MA group and the WN group were higher than that of the EA group (P<0.05), and the range of motion score of Neer test in the MA group was higher when compared with the EA and WN groups (P<0.05). There was no statistical difference in the total score of Neer score among the three groups. VAS score in the EA group was lower than that of either the WN group or the MA group (P<0.05). ADL score in the MA group was lower compared with that of the WN group (P<0.05). PGE2 levels in both the WN group and the MA group were lower than that of the EA group (P<0.05). The total effective rate was 85.71% (30/35) in the MA group, 91.43% (32/35) in the EA group and 90.91% (30/33) in the WN group, there was no statistical differences among the three groups. At the end of the 6-month follow-up visit after treatment, there was no significant difference in the recurrence rate among three groups. No serious adverse reaction was found. CONCLUSIONS: In the treatment of CSP, the short-term effect is equivalent among EA, WN and MA. But, the analgesic effect is the best in the EA group, the treatment for anti-inflammation is the most effective in the MA and WN groups, and the needling technique of Canggui Tanxue in the MA group obtains the most favorable effect of releasing adhesion and recovering the range of motion in the shoulder joint.

Acute calcific periarthritis of acromioclavicular joint: A case report.

Key Clinical Message: It is of utmost importance to be aware of acute calcific periarthritis, as it may confuse the clinicians leading to misdiagnosis. Furthermore, patients may be subjected to various diagnostic and invasive procedures due to a lack of familiarity with this condition. Abstract: Deposition of hydroxyapatite crystals in the para-articular soft tissues is a well-known condition, often involving the shoulder joint. However, the deposition of calcium salts in the para-articular soft tissue of acromioclavicular joint has rarely been described. We report a case of a 55-year-old otherwise healthy man, presented with acute onset of pain and restriction of movement of left shoulder, who was diagnosed based on radiographic findings with calcific periarthritis of the acromioclavicular joint. As suggested by the literatures, he was managed conservatively, and no reoccurrence was reported after the episode.

[Pricking and cupping at Jianbo area combined with conventional acupuncture for scapulohumeral periarthritis of frozen stage: a randomized controlled trial].

OBJECTIVE: To compare the clinical effect of conventional acupuncture combined with pricking and cupping at Jianbo area and conventional acupuncture in the treatment of scapulohumeral periarthritis of frozen stage. METHODS: A total of 66 patients with scapulohumeral periarthritis of frozen stage were randomly divided into a combination group (31 cases) and an acupuncture group (35 cases, 1 case dropped off). Both groups were given functional exercise. Patients in the acupuncture group were treated with acupuncture at Jianyu (LI 15), Jianliao (TE 14), Binao (LI 14) and ashi point on the affected side, once every other day, three times a week, for a total of 4 weeks. On the basis of treatment in the acupuncture group, the patients in the combination group were treated with pricking and cupping at Jianbo area (the area surrounded by the 3 acupoints of Tianzong [SI 11], Naoshu [SI 10] and Jianzhen [SI 9]), once a week for 4 weeks. The University of California-Los Angeles (UCLA) shoulder joint score, visual analogue scale (VAS) score before treatment, after treatment and after 6 months of treatment completion (follow-up) and tenderness threshold before and after treatment, and the clinical effects of the two groups after treatment and in follow-up were evaluated. RESULTS: In the two groups, after treatment and in follow-up, the UCLA shoulder joint scores were higher than those before treatment (P<0.05), and the VAS scores were lower than those before treatment (P<0.05). In the combination group, after treatment and in follow-up, the UCLA shoulder joint score was higher than that of the acupuncture group (P<0.05), and the VAS score was lower than that of the acupuncture group (P<0.05). After treatment, the tenderness thresholds of the two groups were higher than those before treatment (P<0.05), and the tenderness threshold in the combination group was higher than that in the acupuncture group (P<0.05). After treatment and in follow-up, the cured and markedly effective rate of the combination group was 48.4% (15/31) and 51.6% (16/31) respectively, which was higher than 23.5% (8/34) and 23.5% (8/34) of the acupuncture group (P<0.05). CONCLUSION: Pricking and cupping in Jianbo area combined with conventional acupuncture can improve shoulder joint function and relieve shoulder joint pain in patients with scapulohumeral periarthritis of frozen stage, and the curative effect is better than that of single conventional acupuncture.

Comparing the Efficacy of Intra-articular Platelet-Rich Plasma and Corticosteroid Injections in the Management of Frozen Shoulder: A Randomized Controlled Trial.

Introduction Periarthritis of the shoulder, or frozen shoulder (FS), is a common, painful, and disabling condition with varied treatment strategies. Intra-articular (IA) corticosteroid (CS) injections are a popular treatment option, but their efficacy is often temporary. Platelet-rich plasma (PRP) has emerged as an alternative therapy for adhesive capsulitis, but the literature on its effectiveness is limited. This study aimed to compare the efficacy of IA PRP and CS injections in managing FS. Methods In this prospective, randomized study, 68 patients who met the inclusion criteria were enrolled and randomized using a computer-generated table into two groups: Group 1 (IA PRP) received 4 ml PRP, and Group 2 (IA CS) received 2 ml (80 mg) of methylprednisolone acetate mixed with 2 ml normal saline (for a total of 4 ml) as a CS injection in the IA area of the shoulder. Outcome measures included pain; shoulder range of motion (ROM); the condensed version of the disabling conditions of the arm, shoulder, and hand (QuickDASH) score; and the shoulder pain and disability index (SPADI) score. Participants were monitored via follow-up for 24 weeks, with pain and function assessed at each evaluation using the visual analog scale (VAS) score, the SPADI score, and the QuickDASH score. Results The IA PRP injections demonstrated better long-term outcomes than the IA CS injections, significantly improving pain, shoulder ROM, and daily activity performance. After 24 weeks, the mean VAS score in the PRP and methylprednisolone acetate groups was 1.00 (1.0 to 1.0) and 2.00 (2.0 to 2.0), respectively (P≤0.001). The mean QuickDASH score was 41.83 ± 6.33 in the PRP group and 48.76 ± 5.08 in the methylprednisolone acetate group (P≤0.001). The mean SPADI score was 53.32 ± 7.49 in the PRP group and 59.24 ± 5.80 in the methylprednisolone acetate group (P≤0.001), indicating a significant improvement in the PRP group's pain and disability scores after 24 weeks. The rate of complications was similar between the two groups. Conclusions Our findings suggest that IA PRP injections provide better long-term results than IA CS injections for managing FS. Platelet-rich plasma can be used as a treatment modality for better outcomes, particularly when the patient is contraindicated or refuses CS treatment. Further research is needed to evaluate the efficacy of these treatment modalities at different stages of FS and explore the potential benefits of ultrasound-guided injections.

Effectiveness of bee venom acupuncture for patients suffering from periarthritis humeroscapularis.

OBJECTIVE: To evaluate the efficacy of bee venom acupuncture in humeroscapularis (PHS) patients. METHODS: One hundred and twenty patients diagnosed with PHS were assigned into four groups: BV1 (0.01 mg/kg), BV2 (0.005 mg/kg), BV3 (0.0025 mg/kg), and control group (vitamin B1 plus novocain 3% injection) with 15 d of treatment. The outcomes of the study including visual analogue scale (VAS) score and ß-endorphin, inflammatory cytokines including interleukin-10 (IL-10), IL-1ß and tumor necrosis factor α (TNF-α) and shoulder function score were assessed at baseline, after 10 and 15 d of treatment. RESULTS: All four groups reported statistically significant improvement in VAS score, motion range, and shoulder function score ( < 0.01), only the BV3 group showed significant increase of anti-inflammatory (IL-10) and decrease of pro-inflammatory (IL-1ß, TNF-α) cytokines after treatment ( < 0.05). The BV3 group presented a significant difference between all outcomes compared to the control and other groups. CONCLUSION: BV3 groups showed better recovery including reduced pain, improved motor function and normalized inflammatory cytokines than current therapy used in Vietnam and other groups.

Analysis of risk factors for advanced age in patients with frozen shoulder.

OBJECTIVE: To explore the risk factors of elderly patients with frozen shoulder. METHODS: 262 cases of scapulohumeral periarthritis treated in our hospital from January 2020 to December 2020 were analyzed retrospectively. According to the age of patients, patients younger than 60 years old were divided into middle-aged group (101 cases), patients between 60 and 75 years old were divided into old-aged group (91 cases), and patients ≥ 75 years old were divided into old-aged group (70 cases). The general demographic data and clinical data of the three groups were compared. Visual analogue scale (VAS) was used to evaluate the degree of pain. Finally, the dependent variable is set as whether the onset age of scapulohumeral periarthritis patients is advanced. Univariate and multivariate Logistic regression was used to analyze the risk factors of frozen shoulder patients at an advanced age. RESULTS: There were no significant differences in general demographic data, fixed position, hypertension history, smoking history, drinking history, supraspinatus muscular atrophy and physical exercise among the three groups (all P > 0.05). The course of disease, diabetes, surgical treatment, pain degree, operation time, cholecystitis, coronary heart disease, pain degree three months after operation and cervical spondylosis in the elderly group were all higher than those in the middle-aged group and the elderly group, and the differences were statistically significant (all P < 0.05). The course of scapulohumeral periarthritis, the degree of pain and the degree of pain 3 months after operation in the elderly group were higher than those in the middle-aged group, with significant differences (all P < 0.05). Univariate Logistic regression analysis showed that the risk factors of scapulohumeral periarthritis in the elderly included diabetes mellitus (OR = 3.067, 95% CI 1.881-4.587, P < 0.001), operative treatment (OR = 3.076, 95% CI 1.365-6.765, P = 0.006), VAS score (OR = 2.267, 95% CI 1.117-3.887, P = 0.013), operation time (OR = 1.537, 95% CI 1.305-2.579, P < 0.001), cholecystitis (OR = 2.143, 95% CI 1.019-4.876, P = 0.023), coronary heart disease(OR = 3.128, 95% CI 1.428-7.019, P = 0.005), VAS at 3 months after operation (OR = 1.537, 95% CI 0.786-2.635, P = 0.002), and cervical spondylosis(OR = 1.162, 95% CI 1.029-1.321, P = 0.012). Multivariate logistic regression analysis showed that the risk factors for the onset of the disease at advanced age included fatty infiltration (OR = 4.021, 95% CI 2.981-9.682, P < 0.001), surgical treatment (OR = 4.109, 95% CI 1.419-7.832, P = 0.008), VAS score (OR = 3.081, 95% CI 1.042-7.931, P = 0.046) and operation time (OR = 1.537, 95% CI 1.305-2.579, P < 0.001). CONCLUSION: Risk factors of frozen shoulder at advanced age include fat infiltration, surgical treatment, VAS score and surgical time. In clinical practice, we should refer to the above indicators to help patients with early medical intervention and prevent their onset.

ObjectiveTo investigate the clinical efficacy of Guizhi Shaoyao Zhimutang （GZSYZM） combined with fire needling in the treatment of periarthritis of shoulder with wind-cold-dampness impediment syndrome by stimulating pain points and "shoulder three acupoints". MethodA total of 120 patients with periarthritis of shoulder with wind-cold-dampness impediment syndrome， admitted to Hainan General Hospital from August 2020 to August 2022， were randomly divided into two groups using a random number table. The control group （60 cases） received treatment with GZSYZM for two weeks， while the observation group （60 cases） received treatment with GZSYZM combined with fire needling at pain points and "shoulder three acupoints" for two weeks. The clinical efficacy， adverse reactions， shoulder pain intensity， shoulder joint function， and levels of calcitonin gene-related peptide （CGRP）， cyclooxygenase-2 （COX-2）， interleukin （IL）-2， and IL-17 before and after treatment were compared between the two groups. ResultThe total effective rate in the observation group was 88.33% （53/60）， significantly higher than 68.33% （41/60） of the control group （χ²=7.070， P<0.01）. Compared with the results before treatment， both groups showed significant reductions in pain rating index （PRI）， visual analog scale （VAS） scores， present pain intensity （PPI）， and Simplified McGill Pain Questionnaire （SF-MPQ） total scores， as well as serum levels of CGRP， COX-2， IL-2， and IL-17 after treatment （P<0.01）， and improved pain intensity， daily life abilities， joint mobility， muscle strength， and Constant-Murley score （P<0.01）. Compared with the control group after treatment， the observation group showed significantly reduced PRI， VAS score， PPI， SF-MPQ total score， as well as serum levels of CGRP， COX-2， IL-2， and IL-17 （P<0.01）， and increased pain intensity， daily life abilities， joint mobility， muscle strength， and Constant-Murley score （P<0.01）. There was no significant difference in the incidence of adverse reactions between the two groups. ConclusionGZSYZM combined with fire needling at pain points and "shoulder three acupoints" can effectively reduce the levels of serum inflammatory factors and pain mediators， alleviate pain， and improve shoulder joint function in patients with periarthritis of shoulder with wind-cold-dampness impediment syndrome.

Comparison of the Efficacy of Platelet-Rich Plasma (PRP) and Local Corticosteroid Injection in Periarthritis Shoulder: A Prospective, Randomized, Open, Blinded End-Point (PROBE) Study.

Background Periarthritis or frozen shoulder, also called adhesive capsulitis, is characterized by stiffness and pain along with gradual loss of active and passive movement in the glenohumeral joint. More than 2-5% of the population suffers from periarthritis with a higher incidence in the age group of 40-60 years. The various treatment modalities used for its management include simple physiotherapy, short-wave therapy, ultrasonic therapy, transcutaneous electrical nerve stimulation, hydrotherapy, analgesics, intra-articular injections, manipulation under general anesthesia (MUA), and surgical management. The application of intra-articular steroid injection has been a common and efficacious option in rapidly diminishing shoulder pain and disability. Some recent studies reported a better outcome using platelet-rich plasma (PRP) injections in frozen shoulder cases. Hence, this randomized controlled trial was conducted to compare the efficacy of intra-articular injections of PRP and triamcinolone in patients of shoulder periarthritis in a population from the eastern region of India Methodology A total of 60 patients with periarthritis shoulder were allocated into two groups after randomization. Group A received 2 mL autologous PRP, and Group B received 2 mL of triamcinolone (40 mg/mL) intra-articular injection. Patients were followed up on the 4th week, 12th week, and 24th week. The assessment of pain and function using the visual analog scale (VAS) score and the Disabilities of Arm, Shoulder, and Hand (DASH) score, respectively, was done at each follow-up. The primary analyses of both primary and secondary outcomes were conducted in the intention-to-treat (ITT) population. SPSS version 24 (IBM Corp., Armonk, NY, USA) was used for data analysis. Results The mean VAS score in the PRP and triamcinolone groups was 14.33 ± 3.79 and 31.63 ± 7.62, respectively (p = 0.0001) after 24 weeks. The mean DASH score in the PRP and triamcinolone groups was 18.08 ± 8.08 and 31.76 ± 3.63, respectively (p = 0.0001), which shows significant improvement in both pain and disability scores in the PRP group after 24 weeks. Conclusions The triamcinolone group showed better short-term outcomes whereas PRP showed better long-term outcomes in reducing pain and disability scores in terms of VAS and DASH scores.

Arthroscopic capsular release versus manipulation under anaesthesia for treating frozen shoulder - a prospective randomised study.

PURPOSE: Arthroscopic capsular release (ACR) and Manipulation under anaesthesia(MUA) have been widely used in the treatment of frozen shoulder (FS). However, there is only limited Level-I evidence to prefer ACR over MUA. The purpose of our study was to conduct a randomised trial comparing ACR versus MUA to assess the difference in outcome, complications and cost-effectiveness of both procedures. METHODS: From May 2020 to June 2021, patients presenting with FS were randomised into two groups ACR (n = 44) and MUA (n = 41). Patients with arthritis, full-thickness cuff tears, history of trauma/previous surgery around the shoulder were excluded from the study. Range of movement (ROM), pain grading using visual analogue scale (VAS), functional scores- UCLA, CONSTANT and EuroQol-5D scores were measured pre-operatively and post-operatively. MRI was done at three weeks post-operatively for screening complications of either procedure. Quality-adjusted life years (QALY) was used for cost-analysis. RESULTS: Post-operatively, patients had significant improvement in pain, ROM and functional scores in both groups (P < 0.001) with no significant difference between groups at 24 weeks of follow-up. Diabetic patients undergoing ACR had lesser improvement in abduction and external rotation when compared to non-diabetic patients. Labral tears in MUA group and bone bruises in ACR group were the most common complications noted on the post-operative MRI. For ACR cost per QALY gained was 896 USD while that for MUA was 424 USD. CONCLUSION: Both ACR and MUA resulted in good improvement in pain and shoulder function. Good outcomes, simple technique and better cost-effectiveness would still make MUA an attractive option over ACR for treating FS.

Anakinra treatment of acute calcium deposits in hand and wrist.

Acute calcium deposit (ACD) in the hand and wrist is a cause of acute pain due to crystal-induced soft-tissue inflammation. There are no standard management guidelines for this condition, which is frequently treated with non-steroidal anti-inflammatory drugs (NSAIDs), with variable efficacy, some patients presenting symptoms for several months. We retrospectively analyzed the results of all patients treated with anakinra for hand or wrist ACD in our department in 2020. We extracted data on treatment duration, pain, range of motion, skin erythema, hypervascularization, edema, and X-ray findings. Ten patients were treated for hand or wrist ACD with anakinra 100 mg per day for a mean 2.7 days. We observed rapid and significant improvement in pain, range of motion, local erythema and edema from day 2 and a decrease in skin temperature from day 3. Calcifications significantly decreased in size or disappeared in the majority of the patients. There were no adverse events or recurrences at 1 year's follow-up. Anakinra was associated with significant clinical improvement after only two days' treatment and may be considered to treat patients with hand or wrist ACD, especially in case of contraindications to NSAIDs or glucocorticoids. Further controlled studies are needed to confirm the present observations.

[Exploration of the development direction of contemporary acupuncture-moxibustion school: acupuncture-moxibustion treatment for periarthritis of shoulder].

Taking acupuncture-moxibustion for periarthritis of shoulder as an example, the characteristics of contemporary acupuncture-moxibustion school are analyzed in terms of the theories of syndrome treatment, acupoint selection, needle devices and acupuncture techniques, as well as the encountered questions during its development; and the exploratory suggestions are proposed. The contemporary acupuncture-moxibustion school should be developed in three aspects, i.e. constructing data platform, expanding inheritance model and formulating acupuncture-moxibustion standard.

Prognostic factors determining long-term outcomes of conservative treatment for acute calcific periarthritis of the hand.

Acute calcific periarthritis (ACP) of the hand is an uncommon disease that is usually self-limited. Although the conservative treatment is generally considered the primary intervention, the prognostic factors associated with long-term outcomes have yet to be identified. The purposes of this study were to investigate the long-term effects of conservative treatment and identify factors associated with long-term prognosis. We retrospectively reviewed 25 patients with a mean age of 46 years who were diagnosed with ACP of the hand and followed up over more than 2 years. Pain control with nonsteroidal anti-inflammatory drugs and activity restrictions were recommended for the initial treatment. Symptom persistence was defined as a visual analogue scale of more than 1. We compared patients with and without symptom persistence regarding potential prognostic factors such as age, gender, calcification size and type (type 1, amorphous and ill-defined; type 2, homogenous and well-defined), and joints and digits involved. Factors associated with symptom persistence were examined with multivariate analysis. At 2-year follow-up, 19 patients showed complete improvement, whereas 6 reported persistent symptoms. Symptom persistence was independently associated with the thumb involvement (odds ratio (OR), 149.77; 95% confidence interval (CI), 0.61-15.98; P = 0.02) and calcification type 2 (OR, 27.68; 95% CI, 0.50-11.08; P = 0.02). In our study, most patients with ACP of the hand reported symptom improvement with conservative treatment at 2 years of follow-up. Calcification of the thumb or calcification type (homogeneous with a well-defined margin) was independently associated with symptom persistence at 2 years.

Acute calcific periarthritis-a commonly misdiagnosed pathology.

Acute calcific periarthritis (ACP) is a self-limiting, monoarticular, peri-articular process of dystrophic mineral deposition and adjacent inflammation. Patients present with a sudden onset of pain, localised swelling, erythema, tenderness and restricted range of motion. Symptoms reduce in severity within 4-7 days and self resolve in 3-4 weeks. ACP is commonly misdiagnosed, in particular, as infective or inflammatory pathologies such as septic arthritis and gout. This condition has specific imaging findings which allows differentiation from other disorders when combined with the clinical presentation. Prompt diagnosis results in appropriate management and reduces the likelihood of unnecessary diagnostic and therapeutic procedures.
