Effect of extracorporeal shock wave combined with autologous platelet-rich plasma injection on rotator cuff calcific tendinitis: study protocol for a randomized controlled trial.

BACKGROUND: Rotator cuff calcific tendinitis (RCCT) is a common shoulder disease whose main symptoms include shoulder pain, limited mobility, and calcification deposits in the shoulder. Traditional treatment methods have certain limitations, so finding new treatment methods has become the focus of research. Extracorporeal shock wave (ESW) and platelet-rich plasma (PRP) treatments have attracted much attention due to their non-invasive and tissue repair-promoting properties; however, the efficacy of their combined treatment in RCCT remains unclear. METHODS: This study is designed as a single-center, assessment-blind, randomized controlled clinical trial with three parallel groups. Sixty subjects will be recruited and randomly divided into the ESW group, PRP group, and ESW combined with PRP group, in a 1:1:1 ratio. The entire intervention period is 4 weeks, and the follow-up period is 4 weeks. Outcomes will be measured at baseline (T0), after 1 week of intervention (T1), after 2 weeks of intervention (T2), after 4 weeks of intervention (T3), and after an additional 4 weeks of follow-up period (T4). The primary endpoint is the VAS score. Secondary endpoints are ASES, CMS, UCLA, and the location and size of calcified areas. DISCUSSION: This study aims to evaluate the efficacy of ESW therapy combined with PRP in treating RCCT. We compare the effects of single and combined treatments to explore their impact on disease symptoms, functional improvement, and calcification regression. This provides a scientific basis for identifying more effective treatment options. TRIAL REGISTRATION: ClinicalTrials.gov NCT06372600. Registered on April 17, 2024; version 1.

Effects of radial extracorporeal shock wave with different frequencies on acute skeletal muscle injury in rabbits.

To study the efficacy and possible mechanisms of radial extracorporeal shock wave (rESW) with different frequencies for the treatment of acute skeletal muscle injury in rabbits, 48 rabbits of acute injured biceps femoris were randomly divided into 4 groups. Except for the control group, the other groups were treated by rESW with 5 Hz, 10 Hz and 15 Hz, respectively. The injury symptom index scores (ISISs) in the rESW group were significantly lower than those in the control group, with the lowest in the 10 Hz rESW group. Histomorphological features demonstrated a decrease in mononuclear cells and an increase in new myocytes across all groups, with the rESW group showing the most significant changes. The concentrations of PGE2 and IL-1ß were significantly lower in all rESW groups by ELISA compared to the control group. Additionally, the 10 Hz group had lower concentrations than the 5 Hz and 15 Hz group. Compared with the control group, MyoD of the rESW groups was significantly increased, and the expression level of the 10 Hz group was higher than that of the other groups. In conclusion, rESW with 5 Hz, 10 Hz and 15 Hz take certain curative effects on acute biceps femoris injury in rabbits, and the 10 Hz rESW takes advantage over 5 Hz and 15 Hz rESW.

Extracorporeal Shock Wave Therapy (eSWT) in Spinal Cord Injury-A Narrative Review.

BACKGROUND: Injury of the spinal cord causes motor and sensory dysfunction as well as pathological reflexes, leading to paraplegia or tetraplegia. The sequelae of traumatic spinal cord injury (SCI) are a significant burden and impact on healthcare systems. Despite constant progress in medicine, traumatic SCI still remains irreversible. To date, no satisfying treatment that can enable neuronal regeneration and recovery of function at the damaged level has been found. Hundreds of experiments have been conducted on various possibilities of influencing spinal regeneration; some of them have yielded promising results, but unfortunately, the successes obtained in experimental animals have not translated into humans. METHODS: This narrative review article presents the application of extracorporeal shock wave therapy (eSWT) in patients with SCI. The article has been divided into parts: 1) use of extracorporeal shock wave therapy for regeneration of the spinal cord after traumatic spinal cord injury; 2) application of extracorporeal shock wave therapy in spasticity after spinal cord injury. In both cases, the hypotheses of possible mechanisms of action will be described. RESULTS AND CONCLUSIONS: A small number of clinical trials have demonstrated the potential of eSWT to influence the regeneration of the spine, as an innovative, safe, and cost-effective treatment option for patients with SCI. Some reports have shown that eSWT can improve spasticity, walking ability, urological function, quality of life, and independence in daily life.

Comparison of effectiveness of extracorporeal shock wave therapy and peloidotherapy in patients with plantar fasciitis: a prospective, randomized, controlled study.

Although peloidotherapy and ESWT are effective treatments for plantar fasciitis, there is no comprehensive research that directly compares their effectiveness. Our study aimed to compare the effectiveness of ESWT and peloidotherapy on pain, quality of life and functional status in individuals diagnosed with plantar fasciitis (PF). A total of 78 patients, aged between 18 and 65 years, diagnosed with PF after a thorough anamnesis and physical examination and experiencing heel pain for at least 3 months or longer and who presented to the Clinic between January 2021 and January 2023, were included in the study. Patients were randomly allocated to two groups. The peloidotherapy group received 15 sessions of peloid therapy five days a week for three weeks, while the ESWT group received three sessions of radial-type ESWT once a week for three weeks. Additionally, all patients were given a home exercise program. All patients were evaluated three times for treatment efficacy. Pain levels were assessed using the Visual Analog Scale (VAS) and Heel Tenderness Index (HTI), functional status and quality of life were assessed using the Foot Ankle Outcome Score (FAOS) and Short Form 36 (SF-36), respectively. In both treatment groups, there was a statistically significant improvement in VAS, HTI, FAOS and SF-36 scores at the end of treatment and during the one-month follow-up, compared to the initial baseline values. A statistically significant difference in favor of peloidotherapy was observed in post-treatment symptom and pain scores (p = 0.046). However, this difference did not persist at the one-month follow-up. Both active treatment methods were similarly effective and no superiority was observed between them (p > 0.05). Peloidotherapy and ESWT treatments, along with a home exercise program, were found to be effective for patients with plantar fasciitis. In the conservative treatment of PF, both peloidotherapy and ESWT can be recommended as effective and reliable options.

Cellular regenerative therapy in stress urinary incontinence: new frontiers?-a narrative review.

Background and Objective: Even if treatment with stem cells has been shown to be safe and effective in many patients with stress urinary incontinence (SUI), there is still room for improvement using other regenerative medicine alternatives. Since the beneficial effects of stem cells are probably mediated by secretion of factors rather than by the cells themselves there is a good rationale for further exploring the therapeutic effects of the secretome and/or its components. However, homing factors such as stromal derived growth factor 1 (SDF-1; CXCL12), stimulation of stem cell growth and stem cell mobilization in vivo using low intensity shock wave therapy (Li-ESWT) or regenerative electrical stimulation (RES), are also promising approaches. Methods: A literature search was performed based on PubMed, Scopus and Google Scholar. The search criteria included original basic science articles, systematic reviews and randomized control trials. All studies were published between 2000 and 2023. Selected, peer-reviewed studies were further analyzed to identify those of relevance. Keywords searched included: "female stress incontinence", "homing factors", "CXCL12", "secretome", "low intensity shockwave therapy" and "regenerative electrical stimulation". The peer-reviewed publications on the key word subjects that contained a novel addition to the existing body of literature were included. Key Content and Findings: There is evidence from studies on non-human primates (NHPs) with experimental urinary sphincter injury that CXCL12 can restore sphincter structure and function. Studies with homing factors in human patients with SUI are still to be performed. A large number of clinical studies on the use of secretome or secretome products from mesenchymal stem cells (MSCs) on indications other than human SUI are already available. However, controlled clinical trials on patients with SUI, have to the best of our knowledge, not yet been performed. Also, RES has not been studied in patients with SUI. In contrast, there is clinical evidence that Li-ESWT may improve female SUI. Conclusions: Treatment with homing factors, MSC secretome/secretome components, Li-ESWT and RES are promising frontiers in the treatment of human SUI caused by sphincter damage.

Scalable production of siRNA-encapsulated extracellular vesicles for the inhibition of KRAS-mutant cancer using acoustic shock waves.

Extracellular vesicles (EVs) have emerged as a potential delivery vehicle for nucleic-acid-based therapeutics, but challenges related to their large-scale production and cargo-loading efficiency have limited their therapeutic potential. To address these issues, we developed a novel "shock wave extracellular vesicles engineering technology" (SWEET) as a non-genetic, scalable manufacturing strategy that uses shock waves (SWs) to encapsulate siRNAs in EVs. Here, we describe the use of the SWEET platform to load large quantities of KRASG12C-targeting siRNA into small bovine-milk-derived EVs (sBMEVs), with high efficiency. The siRNA-loaded sBMEVs effectively silenced oncogenic KRASG12C expression in cancer cells; they inhibited tumour growth when administered intravenously in a non-small cell lung cancer xenograft mouse model. Our study demonstrates the potential for the SWEET platform to serve as a novel method that allows large-scale production of cargo-loaded EVs for use in a wide range of therapeutic applications.

Comparative study between retrograde intrarenal surgery and ultrasound- guided shock wave lithotripsy for treatment of 1 to 2 cm radiolucent lower calyceal stones.

Objectives: The objective is to compare the safety and efficacy of retrograde intrarenal surgery (RIRS) and ultrasound-guided (US-guided) shock wave lithotripsy (SWL) for the treatment of radiolucent lower pole calculi of 1-2 cm. Materials and Methods: This prospective randomized study was performed at our tertiary care urology institute of Benha University Hospitals; cases were randomized either to undergo RIRS (Group A) or US-guided SWL with a triple focus system (Group B). The safety and effectiveness of both therapies were compared using new criteria for stone-free rate (SFR): Grade A (absolutely stone free), Grade B (≤2 mm fragments), and Grade C (>2 mm up to 4 mm fragments), fluoroscopy time, operative time, auxiliary procedures, retreatment, and complications. Results: Out of 100 patients, 92 were eligible for this study. RIRS had a higher SFR of 88.9% compared to SWL, 72.3% (P = 0.045). Furthermore, stone-free classification significantly differed between the studied groups (P < 0.001), with Grade A being significantly higher in Group A. Conversely, Grades B and C were lower in Group A. On the other hand, operative and fluoroscopy times were significantly reduced with SWL (P = 0.004 and < 0.001, respectively). While complications did not significantly differ between the two groups (P = 0.340), a significant distinction was observed in terms of the Clavien-Dindo classification. Conclusions: RIRS is an effective and safe option for treating radiolucent lower calyceal stones of ≤2 cm, with a greater SFR and lower need for auxiliary operations. However, Sono SWL is a cost-effective alternative that can achieve a comparable success rate after retreatment sessions.

Effectiveness of various interventions for non-traumatic osteonecrosis: a pairwise and network meta-analysis.

Background: Osteonecrosis of the femoral head (ONFH) is acknowledged as a prevalent, challenging orthopedic condition for patients. Purpose: This study aimed to evaluate the efficacy of various interventions for non-traumatic ONFH and provide guidance for clinical decision-makers. Methods: We searched PubMed, Embase, Cochrane Library, and Web of Science databases from inception to February 2023 for relevant randomized controlled trials evaluating treatments for femoral head necrosis, without language restrictions. Quality evaluation was performed using the Cochrane risk-of-bias assessment tool, and analysis was performed using Stata 15.1. Results: Eleven randomized controlled trials were included in this study. The meta-analysis results revealed that CellTherapy [MD= -3.46, 95%CI= (-5.06, -1.85)], InjectableMed [MD= -3.68, 95%CI= (-6.11, -1.21)], ESWT [MD= -2.84, 95%CI= (-4.23, -1.45)], ESWT+InjectableMed [MD= -3.86, 95%CI= (-6.22, -1.53)] were significantly more effective in improving VAS pain score than CD+PTRI, as well as CD+BG+CellTherapy, and CD+BG. Furthermore, CD+BG+CellTherapy was better than CD+BG [MD= -0.97, 95%CI= (-1.71, -0.19)]. The SUCRA ranking for HHS score indicated that CellTherapy (77%) has the best effectiveness rate, followed by ESWT+InjectableMed (72.2%), ESWT (58.3%), InjectableMed (50%), CD+PTRI (31.4%), and CD+BG (11%). In terms of WOMAC and Lequesne scores, the meta-analysis showed no statistically significant differences between the experimental group CD+BG+CellTherapy and the control group CD+BG. Conclusion: CellTherapy and non-surgical ESWT combined with medication or CellTherapy have the best effect on ONFH. Surgical CD+BG combined with CellTherapy is more effective than CD+BG alone. ESWT+InjectableMed is recommended for short-term or acute onset patients, while ESWT is recommended for long-term patients.

Safety evaluation of extracorporeal shockwave lithotripsy for pancreatic stones: Experience based on a large chronic pancreatitis cohort.

BACKGROUND: The safety of extracorporeal shock wave lithotripsy for pancreatic stones (P-ESWL) and adverse events were not evaluated and classified within large sample population. This study aimed to evaluate the safety and classify the adverse events of P-ESWL based on a large sample cohort. METHODS: This is an observational study based on the large prospective chronic pancreatitis (CP) cohort. Patients with painful pancreatic stones over 5 mm who underwent P-ESWL between March 2011 and June 2018 at Shanghai Changhai Hospital were included. Adverse events after P-ESWL including complications and transient adverse events (TAEs) were recorded. Risk factors of adverse events were analyzed through univariable and multivariable logistics regression analysis. Sensitivity analysis was conducted to test the stability of the study. RESULTS: Totally 2,071 patients underwent 5,002 sessions of P-ESWL were included. The overall complication rate and TAEs rate after all P-ESWL procedures were 5.2% and 20.9%. The complications and TAEs rate decreased obviously within the first 6 sessions. Several independent risk factors for adverse events after P-ESWL were identified. Sensitivity analysis suggested the stability of the results. CONCLUSIONS: P-ESWL is a safe treatment for pancreatic stones. Multiple P-ESWL sessions did not increase the complications and TAEs rate.

Placebo Effect in the Treatment of Patellar Tendinopathy and Its Influencing Factors: Systematic Review With Meta-analysis and Meta Regression of Randomized Controlled Trials.

Background: The effectiveness of nonsurgical treatment of patellar tendinopathy is questioned due to the conflicting results of placebo-controlled randomized controlled trials (RCTs) in which placebo arms often show impressive results. Purpose: To quantify the magnitude of placebo effect of the different nonsurgical treatments of patellar tendinopathy. We also evaluated the influence of patients and treatments characteristics on the response to the placebo. Study Design: Systematic review; Level of evidence, 1. Methods: We searched PubMed, Web of Science, Embase, Scopus, Cochrane Library, and gray literature databases on May 10, 2023, with no time limitation. RCTs on nonoperative treatment of patellar tendinopathy, including a placebo control arm reporting the evolution of symptoms after placebo administration, were included. A single-arm meta-analysis was performed with the Victorian Institute of Sport Assessment-Patella (VISA-P) at mid-term follow-up (3-6 months) as the primary outcome. The VISA-P score at short-term (1-3 months) and long-term (6-12 months) follow-ups, as well as visual analog scale (VAS) for pain at all 3 time points were also analyzed. A subanalysis based on the type of placebo and a meta-regression were conducted to look for potential determinants of the placebo effect. Risk of bias and level of evidence were also analyzed using the revised tool for risk of bias in randomized trials and Grading of Recommendations Assessment, Development and Evaluation. Results: In total, 14 studies (251 patients) were included. VISA-P score at mid-term follow-up (3-6 months) showed statistically significant improvements of 13 of 100 points (P = .001). The change at short-term follow-up (1-3 months) was not statistically significant, whereas at long-term follow-up (6-12 months) it was 27 of 100 points (P < .001). Regarding VAS, results were statistically significant only at mid-term (MD = -1.5/10; P = .02) and long-term (MD = -3.2/10; P < .001) follow-ups. The meta-regression showed positive correlations between the response to placebo and the follow-up length (P < .001) and the effect size in the experimental group (P = .006). The level of evidence was moderate for mid- and long-term results and low for short-term results. Conclusion: The placebo effect for nonsurgical treatments of patellar tendinopathy is long-lasting (up to 12 months) and statistically and clinically significant. It has a perceived and true component and differs among treatments. The duration of follow-up and the effect size of experimental groups correlate with the magnitude of the placebo component, underlining the importance of RCTs to determine the effectiveness of new treatments of patellar tendinopathy.

Investigation of The Effectiveness of Extracorporeal Shock Wave Therapy in Patients Diagnosed with Plantar Fasciitis: Comparison of Radial and Focus Applications.

The aim of the study was to investigate the effectiveness of radial and focus ESWT treatment on pain, function and size of the calcaneal spur in patients with clinical and radiological diagnosis of plantar fasciitis. A total of 112 patients aged between 18 and 95 years, were divided into two groups; group 1, rESWT (2.4 bar 12 hz 2000 beats), group 2 received fESWT (0.14 bar 14 hz 1000 beats) three times a week for three weeks. All patients were evaluated using the Visual Analog Scale (VAS)-pain and Foot Function Index (FFI) before and after the treatment, at 4 week and 12 weeks. Calcaneal spur size was measured radiographically in the patients before and after the treatment at the 12 th week follow-up. According to our records, VAS scores were found to be similar between the groups before treatment and at follow-ups (all p>0.05). In both groups, a significant decrease in VAS scores was found in the follow-ups compared to before treatment (p<0.001). FFI total, pain, activity and disability scores were found to be similar between the groups before treatment and at follow-up (all p>0.05). In both groups, a significant decrease in FFI scores was found in the follow-ups compared to before treatment (p<0.001). Both of rESWT and fESWT were effective in plantar fasciitis treatment there were no significiant difference between two modalities in long term. LEVEL OF CLINICAL EVIDENCE: III.

Extracorporeal Shock Wave and Melatonin Alleviate Joint Capsule Fibrosis after Knee Trauma in Rats by Regulating Autophagy.

BACKGROUND: Joint contracture is a common clinical problem affecting joint function. Capsule fibrosis plays a pivotal role in the progression of Joint contracture. Previous studies have reported that autophagy plays a regulatory role in visceral fibrosis. OBJECTIVE: This study aimed to investigate whether extracorporeal shock wave therapy (ESWT) and melatonin alleviate joint capsule fibrosis in rats with extended knee joint contracture by regulating autophagy. METHODS: A rat knee joint extension contracture model was made. Then, the rats were treated with ESWT, melatonin, ESWT + melatonin, or ESWT + melatonin + mTOR agonist for 4 weeks. The range of motion (ROM) of the knee joints was measured. Joint capsules were collected and observed for pathological changes by H&E and Masson staining. LC3B protein expression was evaluated by immunofluorescence staining. TGF-ß1, MMP-1, Col-Ⅰ, Col-Ⅲ, LC3, ATG7, Beclin1, p-AMPK, p-mTOR and p-ULK1 protein expressions were measured by Western blot assay. RESULTS: The intervention groups had significantly improved ROM of knee joint (P < 0.05), significantly improved pathological changes on HE and Masson staining, significantly decreased protein expressions of TGF-ß1, MMP-1, Col-Ⅰ, Col-Ⅲ and pmTOR (P < 0.05), and significantly increased protein expressions of LC3B, LC3II/LC3I ratio, ATG7, Beclin1, p-AMPK, and p-ULK1 (P < 0.05). Among these groups, the effects demonstrated by the ESWT + melatonin group were the best. With the mTOR agonist supplement, the therapeutic effects of extracorporeal shock waves and melatonin were significantly reduced. CONCLUSION: ESWT plus melatonin alleviated knee joint capsule fibrosis in rats by regulating autophagy.

Analgesic effect and efficacy rate of radial extracorporeal shock wave therapy for plantar fasciitis: a retrospective study.

[Purpose] This study aimed to measure the analgesic effects and efficacy of radial extracorporeal shock wave therapy, for which no consensus has been reached regarding optimal treatment parameters. [Participants and Methods] The study included 40 feet of 40 patients with plantar fasciitis. The visual analogue scale was used to determine the immediate and cumulative effects of radial extracorporeal shock wave therapy as well as the efficacy rate. Efficacy was calculated as a percentage visual analogue scale change of ≥20 mm and visual analogue scale improvement of ≥60%. [Results] Immediate and continued efficacy of radial extracorporeal shock wave therapy was observed and recorded. Efficacy rates based on a percentage visual analogue scale change of ≥20 mm and visual analogue scale improvement of ≥60% were both 57.5%. [Conclusion] Radial extracorporeal shock wave therapy has immediate and cumulative analgesic effects on plantar fasciitis. However, cumulative results of interventions with various treatment parameters are required to determine the optimal treatment parameter settings for diffuse pressure wave therapy for plantar fasciitis.

Electroacupuncture combined with extracorporeal shock wave lithotripsy is beneficial for the expulsion of ureteral calculi: a prospective randomized trial.

PURPOSE: To evaluate the therapeutic efficacy and safety of electroacupuncture (EA) combined with extracorporeal shock wave lithotripsy (ESWL) in treating ureteral calculi. METHODS: This prospective randomized controlled trial included 207 patients with ureteral calculi who were randomly allocated to an experimental group that underwent EA plus ESWL (n = 95) and a control group that underwent only ESWL (n = 112). Imaging examinations were performed at 1, 2, and 4 weeks after the operation, followed by comparing the stone-clearance rate, time to first stone expulsion, and incidence of major complications between the two groups. RESULTS: The stone-clearance rates at 1 (59.1 vs. 37%, P = 0.002), 2 (86.4 vs. 59.3%, P = 0.000), and 4 (90.9 vs. 77.8%, P = 0.013) weeks after the operation in the experimental group were significantly higher than those in the control group. The time to first stone expulsion in the experimental group was significantly lower than that in the control group (1.29 ± 1.55 vs. 2.45 ± 3.11 days, respectively; P = 0.001). However, we found no difference in the incidence of major complications between the two groups (15.9 vs. 17.6%, P = 0.754). CONCLUSION: EA-assisted ESWL significantly improved stone clearance and shortened the time to stone expulsion without elevating the complication risk. However, a large-scale multicenter, prospective study is required to corroborate our conclusions.

Effect of Extracorporeal Shock Wave on IGF-1, TNF-α, and IL-1in Joint Fluid of Patients with Temporomandibular Joint Disorder Syndrome.

As a new therapeutic method, extracorporeal shock wave (ESW) has shown remarkable efficacy in the treatment of temporomandibular joint disorder syndrome. Numerous studies have shown that it has the advantages of noninvasiveness, short treatment time, etc. It can effectively relieve pain and improve symptoms such as joint mobility and opening degree. In clinical practice, through accurate diagnosis and positioning of different patients, appropriate treatment parameters such as therapeutic transducer, frequency and pressure can be selected to significantly improve the efficacy. At the same time, follow-up evaluation after treatment, including temporomandibular joint disorder index and visual analogue score, is also helpful to fully understand the rehabilitation of patients. Extracorporeal shock wave therapy (ESWT) brings new hope to patients with temporomandibular joint disorder syndrome and has a broad application prospect.

The application of extracorporeal shock wave therapy on stem cells therapy to treat various diseases.

In the last ten years, stem cell (SC) therapy has been extensively used to treat a range of conditions such as degenerative illnesses, ischemia-related organ dysfunction, diabetes, and neurological disorders. However, the clinical application of these therapies is limited due to the poor survival and differentiation potential of stem cells (SCs). Extracorporeal shock wave therapy (ESWT), as a non-invasive therapy, has shown great application potential in enhancing the proliferation, differentiation, migration, and recruitment of stem cells, offering new possibilities for utilizing ESWT in conjunction with stem cells for the treatment of different systemic conditions. The review provides a detailed overview of the advances in using ESWT with SCs to treat musculoskeletal, cardiovascular, genitourinary, and nervous system conditions, suggesting that ESWT is a promising strategy for enhancing the efficacy of SC therapy for various diseases.

Extracorporeal Shock Wave Therapy Versus Local Corticosteroid Injection for Chronic Lateral Epicondylitis: A Systematic Review with Meta-Analysis of Randomized Controlled Trials.

Chronic lateral epicondylitis (LE), normally known as tennis elbow, is often managed by conservative treatments. Extracorporeal shock wave therapy (ESWT) and local corticosteroid injection (LCI) are among the most commonly used conservative treatments. However, the comparison between these two interventions remains controversial. This study aimed to compare the effectiveness and safety of ESWT and LCI for chronic LE. A systematic review and meta-analysis was conducted following the Preferred Reporting Items for Systematic Review and Meta-analyses (PRISMA) guidelines. PubMed, EMBASE, Cochrane Library, and Web of Science were searched for eligible studies until April 20, 2024. Meta-analyses were conducted using Manager V.5.4.1. Pooled effect sizes were expressed as the weighted mean difference (WMD) or odds ratio (OR), with 95% confidence intervals (CIs). A total of six randomized controlled trials (RCTs) were included. Compared with LCI, ESWT had inferior change in visual analogue scale (Δ VAS) (WMD, 1.14; 95% CI, 0.80 to 1.48; I2 = 20%; p < 0.001), Δ grip strength (WMD, -4.01; 95% CI, -5.57 to -2.44; I2 = 36%; p < 0.001), change in patient-rated tennis elbow evaluation (Δ PRTEE) score (WMD, 8.64; 95% CI, 4.70 to 12.58; I2 = 0%; p < 0.001) at 1-month follow-up, but superior Δ VAS (WMD, -1.15; 95% CI, -1.51 to -0.80; I2 = 6%; p < 0.001), Δ grip strength (WMD, 2.04; 95% CI, 0.90 to 3.18; I2 = 3%; p = 0.0005), Δ PRTEE score (WMD, -9.50; 95% CI, -14.05 to -4.95; I2 = 58%; p < 0.001) at 3-month follow-up, and superior Δ VAS (WMD, -1.81; 95% CI, -2.52 to -1.10; I2 = 33%; p < 0.001), Δ grip strength (WMD, 3.06; 95% CI, 0.90 to 5.21; I2 = 0%; p = 0.005) at 6-month follow-up. The two groups had a similarly low rate of adverse events (OR, 0.69; 95% CI, 0.05 to 8.60; I2 = 67%; p = 0.77), all of which were mild. Both ESWT and LCI are effective and safe in treating chronic LE. Compared with LCI, ESWT showed inferior short-term (1-month) but superior long-term (3-month and 6-month) outcomes regarding pain relief and function recovery, with a similar rate of mild adverse events.

Efficacy and safety of extracorporeal shock wave therapy for upper limb tendonitis: a systematic review and meta-analysis of randomized controlled trials.

Objective: This study synthesized the highest level of evidence to analyse the effectiveness and safety of using extracorporeal shock wave therapy (ESWT) to treat upper limb tendonitis, which was unknown. Design: We conducted a systematic review and meta-analysis of 18 randomized controlled trials (RCTs) in PubMed, Embase, Web of Science, Medline, and the Cochrane Library. Methods: Two researchers performed the screening, data extraction, literature quality assessment, and heterogeneity analysis of the searched RCTs. Results: The main types of morbidity included rotator cuff tendonitis, lateral epicondylitis, finger tendonitis, and long bicipital tendonitis. The results of the meta-analysis showed that ESWT was effective in relieving pain in all four types of tendonitis. In addition, ESWT was more effective in relieving pain in patients with upper limb tendonitis than placebo at the 3- and 6-month follow-ups, especially with radial ESWT (RESWT). Data analysis of the forest plot showed that the experimental group with ESWT as an intervention had a significant improvement in function in patients with rotator cuff tendonitis at the 3-month follow-up. However, subgroup analysis showed that low-energy ESWT was effective in improving function in patients with calcified and non-calcified rotator cuff tendonitis, whereas it was not effective in relieving pain. Conclusion: ESWT can effectively improve the functional activity in patients with rotator cuff tendonitis and may produce positive analgesic effects in patients with upper limb tendonitis. The incidence of adverse effects is low. Systematic Review Registration: https://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42023403594, identifier: PROSPERO, CRD42023403594.

Focused Extracorporeal Shock Wave Therapy for Painful Delayed Union or Nonunion of Fractures of Interphalangeal Coalition.

Background: Interphalangeal coalition is characterized by fusion of interphalangeal joint between the middle and distal phalanges. Interphalangeal coalition fractures often result in delayed union or nonunion. The purpose of this study was to evaluate the results of focused extracorporeal shock wave therapy (ESWT) for painful delayed union or nonunion of fractures of the interphalangeal coalition. Methods: The study group consisted of 9 patients (9 feet) diagnosed with painful delayed union or nonunion due to persistent pain and no tendency toward bony union for at least 3 months after the interphalangeal coalition fracture on plain radiographs between 2021 and 2023 were included. The mean age was 51.3 years (23-64). Focused ESWT was performed in all patients. The mean time from the date of injury to the start of ESWT was 16.1 weeks (12-15). ESWT was performed every 2 weeks, with each session consisting of 3000 impulses (0.15-0.25 mJ/mm2). Plain radiographs were used to confirm bone union, and visual analog scale (VAS) scores were used for pain assessment. Results: Complete bony union was documented in all 9 patients. The application of focused ESWT was performed a mean of 2.7 times (2-4), and the mean duration from the initiation of treatment to the confirmation of bony union was 7.4 weeks (3.6-12.7). In all cases, the symptoms of swelling and pain were alleviated. The VAS scores exhibited significant improvement, with the mean VAS score decreasing from 3.8 (2-6) before ESWT to 0 after the achievement of union (P < .001). Conclusion: In this small cohort, all patients with painful delayed union or nonunion of fractures at the interphalangeal coalitions achieved complete bony fusion after focused ESWT. Moreover, bony union was observed within 2 months of ESWT initiation. These findings suggest that focused ESWT may be a valuable treatment option for painful delayed union or nonunion of interphalangeal coalition fractures. Level of Evidence: Level IV, case series.

Comparative efficacy of different surgical techniques for pediatric urolithiasis-a systematic review and meta-analysis.

Background: Prior research has assessed a range of surgical treatments for pediatric urolithiasis, emphasizing the necessity of tailor-made therapeutic approaches. These studies also show the adaptability of percutaneous nephrolithotomy (PCNL), retrograde intrarenal surgery (RIRS), and shock wave lithotripsy (SWL) in managing diverse stone dimensions. The goal of this research was to examine the effectiveness of these varying surgical methods in treating pediatric urolithiasis. Methods: Seven digital databases were explored to gather pertinent studies, following the guidelines established by the PRISMA protocol. The retrieved studies were subsequently scrutinized to draw comparisons between the stone-free rate (SFR) and the rate of complications associated with PCNL, RIRS, and SWL. Results: The SFR evaluation revealed no notable disparity between PCNL and RIRS [odds ratio (OR) 1.43, 95% confidence interval (CI): 0.67-3.05, P=0.36]. However, it was observed that both PCNL and RIRS outperformed SWL in terms of effectiveness (OR 2.51, 95% CI: 1.19-5.29, P=0.02 and OR 2.42, 95% CI: 1.41-4.14, P=0.001 respectively). Regarding the complication rates, no significant differences were observed among the three surgical methods (OR 0.67, 95% CI: 0.49-1.59, P=0.05), albeit with various forms of complications being reported. Certain studies associated PCNL with an elevated rate of complications, specifically urinary tract infections (UTIs) and severe hematuria. Conclusions: Though PCNL and RIRS demonstrated higher effectiveness than SWL in achieving SFR, there was no significant disparity in the rates of complications across all three procedures. The study underscores the significance of personalized treatment plans, taking into account aspects such as the dimension and location of the stone, along with patient-specific characteristics.
