Abstract
PURPOSE To assess the technical success, safety and early efficacy of Morton neuroma (MN) cryoneurolysis. MATERIALS AND METHODS Retrospective review of 54 consecutive patients with MN treated with cryoneurolysis after failure of conservative treatment, from September 2022 to June 2023. Outcomes measurements included technical success (defined a successful ultrasound-guided placement of the cryoprobe), procedural safety according to Cirse classification and change in 6 months post-procedure by pain numeric rating scale (pNRS). RESULTS A total of 59 MN were treated during 55 procedures. Mean procedure duration was 47 min, all patients were discharged 2 h after the intervention. Technical success was 98.1%. No Cirse grade 3, 4 or 5 complication was reported. Three grade 2 complication occurred, including two chilblain-type lesions and one bone insufficiency fracture. At 6 months post-procedure, pNRS score was significantly decreased (2.7 ± 2.2 vs 7.1 ± 1.1) (p < 0.0001), with a mean score decrease of 4.1points. Thirty-two patients (60.4%) reported a complete pain relief, 15 (28.3%) a partial pain relief and 6 (11.3%) no pain relief, or increased pain. CONCLUSION Cryoneurolysis seems to be safe for the treatment of Morton neuroma. Six-month pain relief is promising and needs to be confirmed at long term.

Abstract
BACKGROUND Morton's neuroma (MN) is a painful neuropathy resulting from a benign enlargement of the common plantar digital nerve that occurs commonly in the third webspace and, less often, in the second webspace of the foot. Symptoms include burning or shooting pain in the webspace that extends to the toes, or the sensation of walking on a pebble. These impact on weight-bearing activities and quality of life. OBJECTIVES To assess the benefits and harms of interventions for MN. SEARCH METHODS On 11 July 2022, we searched CENTRAL, CINAHL Plus EBSCOhost, ClinicalTrials.gov, Cochrane Neuromuscular Specialised Register, Embase Ovid, MEDLINE Ovid, and WHO ICTRP. We checked the bibliographies of identified randomised trials and systematic reviews and contacted trial authors as needed. SELECTION CRITERIA We included all randomised, parallel-group trials (RCTs) of any intervention compared with placebo, control, or another intervention for MN. We included trials where allocation occurred at the level of the individual or the foot (clustered data). We included trials that confirmed MN through symptoms, a clinical test, and an ultrasound scan (USS) or magnetic resonance imaging (MRI). DATA COLLECTION AND ANALYSIS We used standard Cochrane methodological procedures. We assessed bias using Cochrane's risk of bias 2 tool (RoB 2) and assessed the certainty of the evidence using the GRADE framework. MAIN RESULTS We included six RCTs involving 373 participants with MN. We judged risk of bias as having 'some concerns' across most outcomes. No studies had a low risk of bias across all domains. Post-intervention time points reported were: three months to less than 12 months from baseline (nonsurgical outcomes), and 12 months or longer from baseline (surgical outcomes). The primary outcome was pain, and secondary outcomes were function, satisfaction or health-related quality of life (HRQoL), and adverse events (AE). Nonsurgical treatments Corticosteroid and local anaesthetic injection (CS+LA) versus local anaesthetic injection (LA) Two RCTs compared CS+LA versus LA. At three to six months: • CS+LA may result in little to no difference in pain (mean difference (MD) -6.31 mm, 95% confidence interval (CI) -14.23 to 1.61; P = 0.12, I2 = 0%; 2 studies, 157 participants; low-certainty evidence). (Assessed via a pain visual analogue scale (VAS; 0 to 100 mm); a lower score indicated less pain.) • CS+LA may result in little to no difference in function when compared with LA (standardised mean difference (SMD) -0.30, 95% CI -0.61 to 0.02; P = 0.06, I2 = 0%; 2 studies, 157 participants; low-certainty evidence). (Function was measured using: the American Orthopaedic Foot and Ankle Society Lesser Toe Metatarsophalangeal-lnterphalangeal Scale (AOFAS; 0 to 100 points) - we transformed the scale so that a lower score indicated improved function - and the Manchester Foot Pain and Disability Schedule (MFPDS; 0 to 100 points), where a lower score indicated improved function.) • CS+LA probably results in little to no difference in HRQoL when compared to LA (MD 0.07, 95% CI -0.03 to 0.17; P = 0.19; 1 study, 122 participants; moderate-certainty evidence), and CS+LA may not increase satisfaction (risk ratio (RR) 1.08, 95% CI 0.63 to 1.85; P = 0.78; 1 study, 35 participants; low-certainty evidence). (Assessed using the EuroQol five dimension instrument (EQ-5D; 0-1 point); a higher score indicated improved HRQoL.) • The evidence is very uncertain about the effects of CS+LA on AE when compared with LA (RR 9.84, 95% CI 1.28 to 75.56; P = 0.03, I2 = 0%; 2 studies, 157 participants; very low-certainty evidence). Adverse events for CS+LA included mild skin atrophy (3.9%), hypopigmentation of the skin (3.9%) and plantar fat pad atrophy (2.6%); no adverse events were observed with LA. Ultrasound-guided (UG) CS+LA versus non-ultrasound-guided (NUG) CS+LA Two RCTs compared UG CS+LA versus NUG CS+LA. At six months: • UG CS+LA probably reduces pain when compared with NUG CS+LA (MD -15.01 mm, 95% CI -27.88 to -2.14; P = 0.02, I2 = 0%; 2 studies, 116 feet; moderate-certainty evidence). (Assessed with a pain VAS.) • UG CS+LA probably increases function when compared with NUG CS+LA (SMD -0.47, 95% CI -0.84 to -0.10; P = 0.01, I2 = 0%; 2 studies, 116 feet; moderate-certainty evidence). We do not know of any established minimum clinical important difference (MCID) for the scales that assessed function, specifically, the MFPDS and the Manchester-Oxford Foot Questionnaire (MOXFQ; 0 to 100 points; a lower score indicated improved function.) • UG CS+LA may increase satisfaction compared with NUG CS+LA (risk ratio (RR) 1.71, 95% CI 1.19 to 2.44; P = 0.003, I2 = 15%; 2 studies, 114 feet; low-certainty evidence). • HRQoL was not measured. • UG CS+LA may result in little to no difference in AE when compared with NUG CS+LA (RR 0.42, 95% CI 0.12 to 1.39; P = 0.15, I2 = 0%; 2 studies, 116 feet; low-certainty evidence). AE included depigmentation or fat atrophy for UG CS+LA (4.9%) and NUG CS+LA (12.7%). Surgical treatments Plantar incision neurectomy (PN) versus dorsal incision neurectomy (DN) One study compared PN versus DN. At 34 months (mean; range 28 to 42 months), PN may result in little to no difference for satisfaction (RR 1.06, 95% CI 0.87 to 1.28; P = 0.58; 1 study, 73 participants; low-certainty evidence), or for AE (RR 0.95, 95% CI 0.32 to 2.85; P = 0.93; 1 study, 75 participants; low-certainty evidence) compared with DN. AE for PN included hypertrophic scaring (11.4%), foreign body reaction (2.9%); AE for DN included missed nerve (2.5%), artery resected (2.5%), wound infection (2.5%), postoperative dehiscence (2.5%), deep vein thrombosis (2.5%) and reoperation with plantar incision due to intolerable pain (5%). The data reported for pain and function were not suitable for analysis. HRQoL was not measured. AUTHORS' CONCLUSIONS Although there are many interventions for MN, few have been assessed in RCTs. There is low-certainty evidence that CS+LA may result in little to no difference in pain or function, and moderate-certainty evidence that UG CS+LA probably reduces pain and increases function for people with MN. Future trials should improve methodology to increase certainty of the evidence, and use optimal sample sizes to decrease imprecision.

Abstract
Introduction Morton’s neuroma (MN) is a neuropathic metatarsalgia that causes pain in the plantar aspect of the forefoot generally between the third and fourth metatarsal heads. Treatment can be nonoperative or surgical. Among nonoperative procedures, alcohol injections are still commonly used as considered simple, relatively safe and well-tolerated treatment. However, they present transient and minor complications. Methods Two hundred patients with a diagnosis of MN underwent ultrasound-guided injections with a 47.5% alcohol solution between 2013 and 2020. We reviewed the current literature to highlight the known complications of this treatment, comparing them to the complications developed by our patients. Results Three patients out of 200 patients, developed necrosis of skin and subcutaneous tissue not described in previous studies about MN. Conclusions Our study focuses attention on the complications subsequent to the alcohol injection therapy for MN. Patients and surgeons should be aware that in a small number of cases this therapy can be burdened by necrotic complications of the skin.

Abstract
The recognition of pain and the treatments used for it are vital for all practitioners. Many types of pain can be treated in a locoregional fashion, which has significant implications not just for any individual patient but for society as a whole. These treatments are most effective when performed in a minimally invasive, image-guided fashion. Interventional radiologists should play a central role in providing these lifestyle-limiting treatments. This article describes the medications most typically used for spinal and extra-axial treatments in the management of patients in pain.

Ultrasound-guided Injection Treatments versus Surgical Neurectomy for Morton Neuroma: A Cost-effectiveness Analysis. AJR Am J Roentgenol 2021; 218:234-240.

Abstract
Background: Morton neuroma is a common, painful disorder of the foot with multiple treatment options of varying cost and effectiveness. Objective: The aim of this study was to determine the most cost-effective treatment pathway for symptomatic Morton neuromas that have failed conservative management. Methods: An incremental cost-utility analysis was performed comparing a direct to surgical neurectomy strategy with three injection selective strategies in which one or more ultrasound-guided injection therapies was tried first prior to surgery for non-responders. The three injection selective strategies included: (1) steroid selective (2) alcohol selective, and (3) steroid/alcohol selective in which both steroid injections and alcohol sclerosing injections were trialed successively prior to surgical neurectomy. The direct to surgery approach was compared with the three different injection selective strategies, and with a no-treatment strategy, in a decision-analytic model for a hypothetical group of patients with symptomatic Morton neuromas that had failed conservative management. Model parameters including treatment costs, effectiveness, complication rates, and health utility states were estimated from the literature, reimbursement databases, and expert opinion. The outcome was cost per quality adjusted life year (QALY) with a time horizon of three years. A societal cost perspective was adopted with a willingness to pay threshold of $100,000 per QALY. Sensitivity analyses for key model parameters were performed. Results: For the base input values, the steroid/alcohol selective strategy was dominant and yielded an incremental cost-effectiveness ratio of $4401/QALY compared to no treatment. The probabilistic sensitivity analysis supported this strategy in 74% of 10,000 simulated trials. Results were robust with low sensitivity to most input parameters. However, when the probability of successful alcohol injection treatment dropped below 40%, the steroid selective strategy became most cost-effective. Conclusion: A trial of ultrasound-guided injection therapies for Morton neuroma is a cost-effective strategy compared to proceeding directly to surgical neurectomy. Clinical Impact: Ultrasound-guided injection therapies are indicated as a first line treatment for patients with symptomatic Morton neuromas that have failed conservative management.

Abstract
Objectives Clarity regarding accuracy and effectiveness for interventional procedures around the foot and ankle is lacking. Consequently, a board of 53 members of the Ultrasound and Interventional Subcommittees of the European Society of Musculoskeletal Radiology (ESSR) reviewed the published literature to evaluate the evidence on image-guided musculoskeletal interventional procedures around this anatomical region. Methods We report the results of a Delphi-based consensus of 53 experts from the European Society of Musculoskeletal Radiology who reviewed the published literature for evidence on image-guided interventional procedures offered around foot and ankle in order to derive their clinical indications. Experts drafted a list of statements and graded them according to the Oxford Centre for evidence-based medicine levels of evidence. Consensus was considered strong when > 95% of experts agreed with the statement or broad when > 80% but < 95% agreed. The results of the Delphi-based consensus were used to write the paper that was shared with all panel members for final approval. Results A list of 16 evidence-based statements on clinical indications for image-guided musculoskeletal interventional procedures in the foot and ankle were drafted after a literature review. The highest level of evidence was reported for four statements, all receiving 100% agreement. Conclusion According to this consensus, image-guided interventions should not be considered a first-level approach for treating Achilles tendinopathy, while ultrasonography guidance is strongly recommended to improve the efficacy of interventional procedures for plantar fasciitis and Morton’s neuroma, particularly using platelet-rich plasma and corticosteroids, respectively. Key Points • The expert panel of the ESSR listed 16 evidence-based statements on clinical indications of image-guided musculoskeletal interventional procedures in the foot and ankle. • Strong consensus was obtained for all statements. • The highest level of evidence was reached by four statements concerning the effectiveness of US-guided injections of corticosteroid for Morton’s neuroma and PRP for plantar fasciitis.

[PMID: 32600970 DOI: 10.1016/j.fas.2020.05.001] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/12/2019] [Revised: 04/07/2020] [Accepted: 05/04/2020] [Indexed: 02/04/2023]
Abstract
BACKGROUND The aim of this paper is to analyze the effectiveness of corticosteroid injections (CI), in combination with or without a local anaesthetic, for Civinini-Morton's Syndrome to determine which protocol could be the most appropriate among conservative treatments. METHODS All selected articles were screened using a thorough database search of PubMed, EMBASE and SCOPUS to assess their suitability to the research focus. RESULTS Selection produced 10 articles as full-text, for a total of 590 patients, with a mean follow-up of 14 ± 14.2 (range 3-48) months. Johnson satisfaction scale, resulting from 6 studies, scored 25.6% (range 5-38) and 39.4% (range 15-51.8), respectively completely satisfied and satisfied with minor reservations. Mean VAS, declared in 5 studies, decreased from 70.7 ± 16.5 (range 67-89) to 33.4 ± 7.6 (26-42.5) points (p < 0.01). Most common complication was skin depigmentation in 7 (2.6%) cases. CONCLUSIONS CI appear to be a safe treatment allowing good results with a very low complications rate. A neuroma of 6.3 mm seems to be the cut-off size; below which CI could have best indications and be considered as an intermediate treatment between shoe modifications and more invasive procedures such as percutaneous alcoholization or surgery. LEVEL OF EVIDENCE Level II, systematic review.

Abstract
Mechanical compression of interdigital nerves beneath the deep transverse intermetatarsal ligament and between the metatarsal heads leads to painful irritation and possible fibrosis. Conservative measures of padding and injections often fail to provide long-term relief. Surgical excision provides definitive relief, but the procedure is not without risk. Incomplete excision and stump neuroma formation are a few of the possible complications associate with open excision. This retrospective cohort study was performed to provide a review of the available literature on the identification and treatment of interdigital neuromas and to examine the overall incidence of patient satisfaction after radiofrequency ablation as definitive treatment for interdigital neuroma formation. This study population consisted of 32 patients (25 females and 7 males with 1 patient having bilateral procedures) with a mean age of 46.3 ± 17 (range 31 to 65) years. For all procedures, the median patient satisfaction score was 92.5 (interquartile range 50 to 100) of 100, with a mean follow-up period of > 2.5 years. Only 1 patient in the study population reported no relief after 3 total procedures. Radiofrequency ablation offers a minimally invasive alternative with a short postoperative recovery course and considerably fewer complications compared with surgical excision of the intermetatarsal neuroma as described in prior reports.

Treating Morton's neuroma by injection, neurolysis, or neurectomy: a systematic review and meta-analysis of pain and satisfaction outcomes. Acta Neurochir (Wien) 2021; 163:531-543. [PMID: 32056015 DOI: 10.1007/s00701-020-04241-9] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2019] [Accepted: 01/23/2020] [Indexed: 12/12/2022]
Abstract
BACKGROUND Individual evidence suggests that multiple modalities can be used to treat entrapment pathology by Morton's neuroma, including injection, neurolysis, and neurectomy. However, their impacts on patient pain and satisfaction have yet to be fully defined or elucidated. Correspondingly, our aim was to pool systematically identified metadata and substantiate the impact of these different modalities in treating Morton's neuroma with respect to these outcomes. METHODS Searches of 7 electronic databases from inception to October 2019 were conducted following PRISMA guidelines. Articles were screened against pre-specified criteria. The incidences of outcomes were extracted and pooled by random-effects meta-analysis of proportions. RESULTS A total of 35 articles satisfied all criteria, reporting a total of 2998 patients with Morton's neuroma managed by one of the three modalities. Incidence of complete pain relief after injection (43%; 95% CI, 23-64%) was significantly lower than neurolysis (68%; 95% CI, 51-84%) and neurectomy (74%; 95% CI, 66-82%) (P = 0.02). Incidence of complete satisfaction after injection (35%; 95% CI, 21-50%) was significantly lower than neurolysis (63%; 95% CI, 50-74%) and neurectomy (57%; 95% CI, 47-67%) (P < 0.01). The need to proceed to further surgery was significantly greater following injection (15%; 95% CI, 9-23%) versus neurolysis (2%; 95% CI, 0-4%) or neurectomy (5%; 95% CI, 3-7%) (P < 0.01). Incidence of procedural complications did not differ between modalities (P = 0.30). CONCLUSIONS Although all interventions demonstrated favorable procedural complication incidences, surgical interventions by either neurolysis or neurectomy appear to trend towards greater incidences of complete pain relief and complete patient satisfaction outcomes compared to injection treatment. The optimal decision-making algorithm for treatment for Morton's neuroma should incorporate these findings to better form and meet the expectations of patients.

Abstract
TITLE Non-surgical treatment for Morton's neuroma: a systematic review. BACKGROUND Morton's neuroma (MN) is an entrapment degenerative neuropathy with a strong predilection for the 3rd interdigital web space. The objective of our study was to identify the most significant evidence produced for the non-operative treatment of Morton's neuroma and assess outcomes of these interventions. METHOD The electronic databases Medline, Ovid EMBASE, CINAHL and Cochrane CENTRAL from inception to October 2018 were searched. Two independent reviewers assessed the quality of the studies using the Modified Coleman Criteria. Statistics were combined across cohort studies to calculate pooled mean results, and improvements in outcomes. RESULTS Initial electronic and hand search identified 486 studies. After title and abstract review there were 38 that went on to full-text review. Finally, 22 studies were included in the final review. We identified 9 different non-operative treatment modalities; Corticosteroid injection, Alcohol injection, Extra-corporeal Shockwave therapy (ESWT), Radiofrequency Ablation (RFA), Cryoablation, Capsaicin injection, Botulinum toxin, Orthosis and YAG Laser Therapy. Corticosteroid showed a statistically significant reduction in mean VAS over all their studies (p < 0.01), with 50% success at 12 months. Alcohol showed promising short-term pain-relieving results only. Orthotics, Capsaicin injections, Cryoablation, Botulinum toxin, RFA and ESWT did show statistically significant improvements, but with limitation to their application. CONCLUSION Following review, the authors would recommend the use of corticosteroid injections to treat Morton's neuromas. The authors feel that radio-frequency ablation and cryoablation would benefit from further well designed randomised controlled trials.

Abstract
INTRODUCTION There is a lack of supporting evidence for conservative treatments involving Morton's Neuroma, which has often a clinical presentation with many associated complications such as functional impairment and chronic pain. This case study assessed the effects of a combined physical therapy treatment for Morton's Neuroma, an injury often referred for surgery. METHODS The patient suffered a long-standing Morton's Neuroma and received 6 combined physical therapy sessions that included soft-tissue massage, joint mobilization, strengthening therapeutic exercises and pain education. Values for pain with deep pressure, pain maladaptive beliefs and functionality were taken using clinical testing and questionnaires. RESULTS After the intervention was successfully completed, pain when applying deep pressure resolved. Functionality involving the toe-to-wall test showed an improvement in ankle dorsiflexion and better results were found in both the LEFS and FAAM questionnaires. Pain maladaptive beliefs, assessed with the Pain Catastrophizing Scale and the Pain Awareness Questionnaire also reflected an improvement. CONCLUSION A combined physical therapy approach shows encouraging results in the treatment of Morton's Neuroma.

Abstract
BACKGROUND Nonoperational treatments for Morton's neuroma remain controversial because it is believed that sclerosing injections do not change nerve fibers on a cellular level. Up to 80% success rates with 4% ethanol sclerosing have been documented, and the remainder required operational removal of the painful nerve. We sought to evaluate the histologic characteristics of Morton's neuromas treated with 4% ethanol sclerosing injection versus corticosteroid injection alone in patients who required removal of the nerve for pain relief. METHODS A retrospective histologic review was performed of 23 consecutive patients who were treated with either sclerosing injection or nonsclerosing injection and underwent nerve removal between September 1, 2012, and February 28, 2015. RESULTS Of 19 patients who met the inclusion criteria, eight received sclerosing injections and 11 received nonsclerosing injections. Intraneural fibrosis was more severe in the nonsclerosing injection group (P = .008). CONCLUSION Histologic changes are seen in Morton's neuroma with the use of 4% ethanol sclerosing injection, contrary to findings from previous studies.

Abstract
Forefoot neuromas are a common pathology that is seen in a wide variety of patients. Although conservative treatment is successful with modification of shoes/inserts or injections, surgical intervention is occasionally needed to alleviate the discomfort. Most surgical procedures for neuromas have a good outcome. There are times when the outcome is not optimal and revision surgery may be needed. This article describes revision surgery techniques that may lead to an improved outcome. Also discussed is the opportunity to reduce recurrence through the understanding of neuroma biology, diagnosis, and treatment options.

Abstract
BACKGROUND Morton's neuroma is a common cause of forefoot pain. Various conservative methods (injections of various pharmacologic agents) have been published with an outcome of 6%-75% success rate (free of pain in daily life) per injection. The aim of the present study was to assess the outcome of an improved localization technique, a higher dosage, and a higher percentage of ethanol. METHODS Using fluoroscopic and electroneurographic guidance, 2.5 mL of 70% ethanol were injected into 33 feet with a magnetic resonance imaging (MRI)-verified neuroma. We evaluated patients at up to 5-year follow-up. RESULTS A "success rate" of more than 82% per single injection (defined as free of pain in daily life) was achieved and no recurrence was seen over 5 years. All scores (visual analog scale; Short Form-36 subscales, American Orthopaedic Foot & Ankle Society ankle-hindfoot score) showed significant improvement (P < .0001). Mean 1.2 injections were necessary. No significant side effects were seen. However, some mild pain persisted in some patients who participated in sports. CONCLUSION The injection of 2.5 mL of 70% ethanol under fluoroscopic and electroneurographic guidance was a safe method for the treatment of MRI-verified Morton's neuromas. Combining the effect of a higher percentage of alcohol and a higher dosage and an improved localization technique resulted in a high rate of patients without pain.

Abstract
BACKGROUND Percutaneous alcoholization with phenol by electrostimulation guidance for the treatment of Morton's neuroma is proposed to determine a permanent chemical neurolysis. METHODS 115 patients for 125 Morton's neuromas were treated. Ten patients were affected by multiple neuromas. Visual Analogue Scale and AOFAS score were used for the clinical assessment. RESULTS The mean follow-up was 8,3 years. The pre-alcoholization VAS was 85.84 ± 12.00, while at follow-up scored 28.85 ± 31.35, showing a significant decrease improving in 113/125 cases (90.4%). Treatment was considered successful with a reduction of the VAS value superior to 50% in 89 out of 125 patients (71.2%). The mean overall AOFAS score at -up was 85.09 ± 13.41. CONCLUSIONS Needle-electrode guided percutaneous alcoholization is an outpatient, minimally invasive procedure with low rate of complications. Better results of those obtained with traditional conservative treatments and comparable with those reported with other alcohols injections or surgical nerve excision were observed.

Abstract
Morton's neuroma is a common pathology affecting the forefoot. It is not a true neuroma but is fibrosis of the nerve. This is caused secondary to pressure or repetitive irritation leading to thickness of the digital nerve, located in the third or second intermetatarsal space. The treatment options are: orthotics, steroid injections and surgical excision usually performed through dorsal approach. Careful clinical examination, patient selection, pre-operative counselling and surgical technique are the key to success in the management of this condition.

Abstract
Metatarsalgia is a common foot disease with a multitude of causes. Proper identification of underlying diseases is mandatory to formulate an adequate treatment. Multiple surgical solutions are available to treat metatarsalgia. Only limited scientific evidence is available in the literature. However, most of the techniques used in the treatment of metatarsalgia seem to be reasonable with acceptable results.

Abstract
BACKGROUND When using a dorsal approach for Morton's neuroma excision, the most common complication is recurrent Morton's neuroma. The present cadaveric study demonstrates how far proximally the nerve is resected during a dorsal approach and examines both the laminar spreader and Gelpiretractor to determine which instrument facilitates maximal proximal resection of the nerve. METHODS This study involved 12 fresh-frozen cadaver specimens, each of which underwent a dorsal approach to the interdigital nerve with proximal resection. Either a laminar spreader or a Gelpi retractor was used to improve visualization of the intermetatarsal space. The interdigital nerve was then resected, and the lengths of the cut nerves were compared based on the retractor employed. RESULTS The mean length of proximal resection in the second intermetatarsal space was 2.42 cm when using the laminar spreader and 1.93 cm when using the Gelpi retractor (P = .252). In the third intermetatarsal space, the mean length of proximal resection was 2.14 cm when using the Laminar spreader and 1.48 cm when using the Gelpi retractor (P = .166). CONCLUSION This study demonstrates how far proximal the interdigital nerve is resected during a dorsal approach to Morton's neuroma and shows no statistically significant difference between the Laminar spreader and the Gelpi retractor.

Abstract
PURPOSE To evaluate the feasibility and efficacy of ultrasound-guided microwave ablation for the treatment of inguinal neuralgia. MATERIALS AND METHODS A retrospective review of 12 consecutive ultrasound-guided microwave ablation procedures was performed of 10 consecutive patients (8 men, 2 women; mean age, 41 years [range, 15-64 years]), between August 2012 and August 2016. Inclusion criteria for inguinal neuralgia included clinical diagnosis of chronic inguinal pain (average, 17.3 months [range, 6-46 months]) refractory to conservative treatment and a positive nerve block. Pain response-reduction of pain level and duration and percent pain reduction using a 10-point visual analog scale (VAS) at baseline and up to 12 months after the procedure-was measured. Nine patients had pain after the inguinal hernia repair, and 1 patient had pain from the femoral artery bypass procedure. The microwave ablation procedure targeted the ilioinguinal nerve in 7 cases, the genitofemoral nerve in 4 cases, and the iliohypogastric nerve in 1 case. RESULTS Average baseline VAS pain score was 6.1 (standard deviation, 2.5). Improved pain levels immediately after the procedure and at 1, 6, and 12 months were statistically significant (P = .0037, .0037, .0038, .0058, respectively). Also, 91.7% (11/12) of the procedures resulted in immediate pain relief and at 1 month and 6 months. At 12 months, 83.3% (10/12) of patients had an average of 69% ± 31% pain reduction. Percent maximal pain reduction was 93% ± 14% (60%-100%), and the average duration of clinically significant pain reduction was 10.5 months (range, 0-12 months.). No complications or adverse outcomes occurred. CONCLUSIONS Ultrasound-guided microwave ablation is an effective technique for the treatment of inguinal neuralgia after herniorrhaphy.

Abstract
Background Morton’s neuroma (MN) is a compressive neuropathy of the common plantar digital nerve. It is a common compressive neuropathy often causing significant pain which limits footwear choices and weight bearing activities. This paper aims to review non-surgical interventions for MN, to evaluate the evidence base for the clinical management of MN. Methods Electronic biomedical databases (CINAHL, EMBASE, MEDLINE and Cochrane) were searched to January 2018 for studies evaluating the effectiveness of non-surgical interventions for Morton’s neuroma. Outcome measures of interest were treatment success rate (SR) (binary) and pain as measured using 100-point visual analogue scale (VAS) (continuous). Studies with and without control groups were included and were evaluated for methodological quality using the Downs and Black Quality Index. Results from randomised controlled trials (RCT) were compared between-groups, and case series were compared pre- versus post-treatment. Effect estimates are presented as odds ratios (OR) for binary data or mean differences (MD) for continuous data. Random effects models were used to pool effect estimates across studies where similar treatments were used. Heterogeneity was assessed using the I2 statistic. Results A total of 25 studies met the inclusion criteria, seven RCTs and 18 pre/post case series. Eight different interventions were identified, with corticosteroid or sclerosing injections being the most often reported (seven studies each). Results from a meta-analysis of two RCTs found corticosteroid injection decreased pain more than control on VAS (WMD: -5.3, 95%CI: -7.5 to − 3.2). Other RCTs reported efficacy of: manipulation/mobilisation versus control (MD: -15.3, 95%CI: -29.6 to − 1.0); extracorporeal shockwave therapy versus control (MD: -5.9, 95%CI: -21.9 to 10.1). Treatment success was assessed for extracorporeal shockwave therapy versus control (OR: 0.3, 95%CI: 0.0 to 7.1); and corticosteroid injection vs footwear/padding (OR: 6.0, 95%CI: 1.9 to 19.2). Sclerosing and Botox injections, radiofrequency ablation and cryoneurolysis have been investigated by case series studies, however these were of limited methodological quality. Conclusions Corticosteroid injections and manipulation/mobilisation are the two interventions with the strongest evidence for pain reduction, however high-quality evidence for a gold standard intervention was not found. Although the evidence base is expanding, further high quality RCTs are needed.

Lorenzon P, Rettore C. Mechanical Metatarsalgia as a Risk Factor for Relapse of Morton's Neuroma After Ultrasound-Guided Alcohol Injection. J Foot Ankle Surg 2019; 57:870-875.

Abstract
Although many treatment modalities are available for Morton's neuroma, the injection of the neuroma with alcohol has gained popularity. However, recently, some investigators have observed a progressive deterioration in pain scores for patients initially pain free after the treatment. The purpose of the present retrospective comparative study was to determine whether mechanical metatarsalgia is related to symptom recurrence. We included 104 consecutive cases of ultrasound-guided alcohol injection for Morton's neuroma in 92 patients. Of these 104 cases, 51 were in group A (49%; Morton's neuroma) and 53 in group B (51%; Morton's neuroma associated with mechanical metatarsalgia). We evaluated each patient using a visual analog scale and American Orthopaedic Foot and Ankle Society forefoot scale, and Johnson satisfaction scale, with a mean follow-up period of 24 (range 12 to 39) months. Concomitant functional and mechanical disorders have been identified and treated with orthopedic inserts. The present study compared the clinical results and recurrence of symptoms in patients with isolated Morton's disease or Morton's disease associated with mechanical metatarsalgia. Of the 104 cases, the patients for 93 cases (89%) were completely satisfied or satisfied with minor reservations. No major complications developed. Symptoms recurred in 6 patients (6%), in whom neuroma was associated with mechanical disorders (p = .0269). Ultrasound-guided alcohol injection of Morton's neuroma is a relatively safe and well-tolerated treatment. Symptom recurrence is often associated with mechanical metatarsalgia. The treatment of the concomitant anatomical and functional disorders that target the genesis of the neuroma has an important role in the prevention of recurrence of this pathology.

Abstract
Among the many causes of forefoot pain, Morton's neuroma (MN) is often suspected, particularly in women, due to its high incidence. However, there remain controversies about its relationship with symptomatology and which diagnostic and treatment choices to choose. This article mainly focuses on the role of the various imaging methods and their abilities to support an accurate diagnosis of MN, ruling out other causes of forefoot pain, and as a way of providing targeted imaging-guided therapy for patients with MN.

Abstract
BACKGROUND The treatment of Morton's neuroma (MN) can be operative, conservative and infiltrative. Our aim was the evaluation of evidence on outcomes with different types of conservative, infiltrative and surgical treatment in patients affected by primary MN. METHODS The bibliographic search was conducted in MEDLINE, Cochrane Library, DARE. Only studies in English were collected. The last search was in August 2015. Case series and randomized controlled trials (RCTs) assessing patients' satisfaction or pain improvement at an average follow-up of at least 6 months after treatment of primary MN were included. Two reviewers selected the studies, evaluated their methodological quality, and retrieved data independently. RESULTS Of 283 titles found, only 29 met the inclusion criteria. Data showed better outcomes with operative treatment. CONCLUSIONS The evaluated case series and few RCTs showed better results with invasive treatment. More and better RCTs which evaluate risk-benefit ratio are required to confirm these results.

Abstract
AbstractA painful neuroma is a common complication of a peripheral nerve injury or amputation, and it can cause tremendous pain that is resistant to most analgesics. Furthermore, painful neuromas have a high postoperative recurrence rate. Painful neuromas are often accompanied by functional disorders, drastically reducing the patient’s quality of life. Several pathophysiological mechanisms have been proposed to explain this type of neuropathic pain, including peripheral and central sensitisation and the involvement of nerve growth factor, α-smooth muscle actin, the cannabinoid CB2 receptor and structural changes in neuroma fibres. Nevertheless, the mechanisms of neuroma-associated pain are not fully understood, contributing to the challenge of managing patients with painful neuromas. There are several effective treatment methods, although none are universally accepted. This review summarises the common mechanisms and treatments of painful neuromas, attempting to link the mechanisms and treatments. We hope to provide useful guidelines for choosing the appropriate treatment for the management of painful neuromas.

Abstract
An intermetatarsal neuroma is a plantar digital neuritis causing metatarsalgia of the affected inter-metatarsal space. At present the evidence to support the management of the condition is poor with only some quality evidence supporting the short-term management of intermetatarsal neuromas using steroid injections. Some authors have supported the use of alcohol sclerosing intra-lesional injections to treat intermetatarsal neuromas. Following a search of the evidence 11 articles were identified. The systematic review found that alcohol injections appear to be safe although some papers report a short-term side effect of a flogistic reaction and there are variances in the alcohol concentration used and guiding verses not guiding the injection using ultrasound imaging. Some of the evidence may suggest a sclerosing histological effect of the nerve. However, all the studies reviewed present a research design offering a low level of evidence that is open to methodological biases and interpretation. Thus, this review found insufficient high-quality research evidence to afford conclusions on the management of intermetatarsal neuromas with alcohol sclerosing agent injections.

Abstract
Morton's neuroma is one of the most common causes of metatarsalgia. Despite this, it remains little studied, as the diagnosis is clinical with no reliable instrumental diagnostics, and each study may deal with incorrect diagnosis or inappropriate treatment, which are difficult to verify. The present literature review crosses all key points, from diagnosis to surgical and nonoperative treatment, and recurrences. Nonoperative treatment is successful in a limited percentage of cases, but it can be adequate in those who want to delay or avoid surgery. Dorsal or plantar approaches were described for surgical treatment, both with strengths and weaknesses that will be scanned. Failures are related to wrong diagnosis, wrong interspace, failure to divide the transverse metatarsal ligament, too distal resection of common plantar digital nerve, an association of tarsal tunnel syndrome and incomplete removal. A deep knowledge of the causes and presentation of failures is needed to surgically face recurrences.

Abstract
There are several forefoot conditions that can result in metatarsal head pain. Various points of the gait cycle can predispose the metatarsal heads to pain based on intrinsic and extrinsic imbalances. Metatarsalgia can further be classified according to primary, secondary, or iatrogenic etiologies. Within these groups, conservative management is the first line of treatment and can often obviate surgical intervention. Depending on the cause of pain, proper shoewear, orthoses, and inserts coupled with targeted physical therapy can alleviate most symptoms of metatarsalgia and lesser toe deformities.

Abstract
PURPOSE Morton's neuroma (MN) is a leading cause of disability. The purpose of this study was to investigate the effectiveness of radiofrequency (RF) in patients with chronic pain refractory to conservative therapies. METHODS Between September 2012 and December 2016, RF was performed on 52 patients. A sterile RF needle probe (22G, 5-cm needle with 10-mm electrode active tip) was inserted between the toes into the intermetatarsal space at the center of the lesion. Potential complications of the intervention and post-procedure care were examined. All patients provided written, informed consent. All percutaneous procedures were performed with the NeuroTherm® NT1100 (Neurotherm Inc., M.) device and using ultrasound guidance (Philips IU22). Continuous RF was performed with one cycle of 90 s and with the probe tip maintaining a temperature of 85 °C (impedance 95-210 mΩ). RESULTS Mean VAS score before the procedures was 9.0 ± 0.6. A reduction of pain intensity was achieved after 1 week by RF (mean VAS scores 3.7 ± 0.9; p < 0.05), with a stabilization of the painful symptomatology in the following months and after 1 year of treatments (mean VAS scores 2.0 ± 0.4 after 12 months, p < 0.05). The FHSQ scores showed improved quality of life (QOL) in all patients at 6 months (p < 0.05) and 1 year (p < 0.05) of RF. No patients developed complications. CONCLUSIONS RF is a safe, efficient, and minimally invasive technique for the treatment of symptomatic MN.

Abstract
BACKGROUND The effectiveness of corticosteroid injection for the treatment of Morton's neuroma is unclear. In addition, most of the studies related to it are case-control or retrospective case series. The purpose of this study was to compare the effectiveness between corticosteroid injection associated with local anesthetic and local anesthetic alone (placebo control group) for the treatment of Morton's neuroma. METHODS Forty-one patients with a diagnosis of Morton's neuroma were randomized to receive 3 injections of either a corticosteroid plus a local anesthetic or a local anesthetic alone. The patients and the researcher who collected data were blinded to the treatment groups. The visual analog scale for pain and the American Orthopaedic Foot & Ankle Score (metatarsophalangeal/interphalangeal score) were obtained at baseline, after each injection, and at 3 and 6 months after the last injection. RESULTS There were no significant between-group differences in terms of pain and function improvement at 3 and 6 months after treatment completion in comparison with baseline values. At the end of the study, 17 (48.5%) patients requested surgical excision of the neuroma: 7 (44%) in the experimental group and 10 (53%) in the control group ( P = 1.0). CONCLUSION The injection of a corticosteroid plus a local anesthetic was not superior to a local anesthetic alone in terms of pain and function improvement in patients with Morton's neuroma. LEVEL OF EVIDENCE Level I, randomized controlled trial.

Abstract
OBJECTIVE The objective of our study was to retrospectively assess for differences in imaging appearances of Morton neuromas before and after laser therapy using diagnostic ultrasound (US). MATERIALS AND METHODS A retrospective review was performed to identify patients who underwent US imaging to evaluate for Morton neuroma during the study period (June 1, 2013-July 1, 2014); of the 42 patients identified, 21 underwent US evaluations before and after laser therapy. US reports and images were reviewed and correlated with clinical history. The final study group consisted of 21 patients who had a total of 31 Morton neuromas evaluated using US after treatment. A retrospective review was then performed to characterize the appearances of these lesions before and after therapy followed by an analysis of variables. RESULTS Retrospective US review of 31 pretreatment Morton neuromas showed fusiform, heterogeneously hypoechoic masses with well-defined borders in most cases and that pain was reported when transducer pressure was applied in 97% (30/31) of cases. After treatment, lesions showed ill-defined borders (23/31), and pain with application of transducer pressure was either significantly decreased or absent (29/31); these findings were concordant with the clinical findings. Both of these characteristics were statistically significant (p < 0.0001). In addition, more Morton neuromas occurred in the second intermetatarsal space than in the third intermetatarsal space (p < 0.0001). CONCLUSION US may be used to identify posttreatment changes after laser therapy of Morton neuromas. Posttreatment changes include ill-defined borders and less pain or the absence of pain with the application of transducer pressure. These criteria may be applied in future clinical studies evaluating the efficacy of laser therapy for Morton neuroma.

Abstract
BACKGROUND Traumatic neuromas are rare benign tumors, which are common in trauma or post-operation and accompanied with obvious symptoms of pain. This study will show the superficial peroneal nerve neuroma occurring after resection of hemangioma. CASE PRESENTATION A 44-year-old male had an operation of the right leg cavernous hemangioma resection in 1995. Half a year after the operation, pain around the wound appeared and gradually aggravated. The patient had the lesion exploration resection in 2013, and the pathological result showed traumatic neuroma. Within half a year of the second operation, severe pain showed up again, so neuroma resection proceeded in May 2015. The postoperative pathological and immunohistochemical results showed traumatic neuroma. According to the postoperative follow-up, there were no symptoms of pain appearing again. LITERATURE REVIEW The pain is obvious, and B ultrasonography is the most efficient way to find neuromas. Both conservative and operative therapy have their advantages and disadvantages. CONCLUSIONS There remain many unanswered questions in relation to the treatment of traumatic neuromas, and further research is required, although we have already had adequate understanding of traumatic neuromas.

Abstract
Posterior tarsal tunnel syndrome is the result of compression of the posterior tibial nerve. Anterior tarsal tunnel syndrome (entrapment of the deep peroneal nerve) typically presents with pain radiating to the first dorsal web space. Distal tarsal tunnel syndrome results from entrapment of the first branch of the lateral plantar nerve and is often misdiagnosed initially as plantar fasciitis. Medial plantar nerve compression is seen most often in running athletes, typically with pain radiating to the medial arch. Morton neuroma is often seen in athletes who place their metatarsal arches repetitively in excessive hyperextension.

Abstract
BACKGROUND The aim of this study was to evaluate the efficacy of extracorporeal shockwave therapy (ESWT) for the treatment of Morton's neuroma by measuring changes in patient pain, function, and neuroma size. METHODS Patients with Morton's neuroma were randomly assigned to either the ESWT group or the sham stimulation group. Outcome measures, including visual analog scale (VAS) and American Orthopaedic Foot and Ankle Society lesser toes (AOFAS) scores, were assessed at baseline and 1 and 4 weeks after treatment. The Johnson satisfaction test was also performed 1 and 4 weeks after treatment. The neuroma diameter was measured using ultrasonography at baseline and 4 weeks after treatment. RESULTS Patients receiving ESWT exhibited significantly decreased VAS scores 1 and 4 weeks after treatment relative to baseline, and AOFAS scores were significantly improved 4 weeks after treatment relative to baseline. In the sham stimulation group, VAS and AOFAS scores showed no significant changes at any time after treatment. Neither group showed significant changes in Johnson satisfaction test results or neuroma diameter. CONCLUSIONS These results suggest that ESWT may reduce pain in patients with Morton's neuroma.

BACKGROUND This study investigated factors that may predict the need for Morton's neuroma (MN) to undergo further treatment within 2 years of a single ultrasound-guided corticosteroid injection. METHODS A retrospective study was undertaken over a three-year period. The data was stratified into two groups: Group A - did not receive further intervention and Group B - received further treatment. We investigated age, gender, neuroma size and presence of other forefoot pathology or ipsilateral neuromas. RESULTS 54 patients (57 feet) were reviewed. 29 feet (51%) required further treatment within 2 years (11 repeat injections, 18 surgical excisions). Binary logistic regression showed that larger neuromas (p=0.011) and younger patients (p=0.007) predicted the need for further intervention but not gender (p=0.272). The distribution of concomitant forefoot pathology and ipsilateral neuromas were similar between the two groups. CONCLUSION Size and age appear to be predictors for further treatment of MN within 2 years of corticosteroid injection.

Abstract
UNLABELLED Tumors of the foot and ankle are rarely encountered in the general patient population. Even among studies of tumor patients, foot and ankle neoplasms are uncommon. Given the weight-bearing demands of the foot and its relatively small area, even small masses are likely to be symptomatic and/or palpable to both patient and physician. Only 3% of osseous neoplasms are found in this region, while 8% of benign soft tissue tumors and 5% of malignant soft tissue tumors are localized to the foot and ankle. Despite the rarity of presentation, it is important for orthopaedic surgeons to be familiar with the diagnostic criteria and therapeutic options for these patients, as each tumor varies in its presentation, level of aggressiveness, and natural history of the disease. With appropriate diagnostic tests and treatment, patients can anticipate a reasonable chance of survival and preservation of function. In this review article, the authors survey the current literature regarding the presentation, diagnostic workup, and treatment for the most common benign and malignant tumors of the foot and ankle. LEVELS OF EVIDENCE Level IV: Literature Review.

Abstract
The use of diagnostic and interventional ultrasound has significantly increased over the past decade. A majority of the increased utilization is by nonradiologists. In sports medicine, ultrasound is often used to guide interventions such as aspirations, diagnostic or therapeutic injections, tenotomies, releases, and hydrodissections. This American Medical Society for Sports Medicine (AMSSM) position statement critically reviews the literature and evaluates the accuracy, efficacy, and cost-effectiveness of ultrasound-guided injections in major, intermediate, and small joints, and soft tissues, all of which are commonly performed in sports medicine. New ultrasound-guided procedures and future trends are also briefly discussed. Based upon the evidence, the official AMSSM position relevant to each subject is made.

Abstract
OBJECTIVE The purpose of this retrospective case series is to describe treatment outcomes for patients with plantar digital neuralgia (PDN) (Morton's neuroma) who were treated using foot manipulation. METHODS Charts were reviewed retrospectively for patients with a diagnosis of PDN and who received a minimum of 6 treatments consisting of manipulation alone. Visual analogue pain scales (VAS) and pressure threshold meter readings (PTM) were extracted as outcome measures. RESULTS Thirty-eight cases met inclusion criteria. Mean pretreatment duration of pain was 28 months. Mean pretreatment VAS was 69.5/100 mm. Mean pretreatment PTM was 2.54 Kp. By the sixth treatment, 30 (79%) of the 38 patients scored a VAS of 0 mm and a further 4 (10%) were below 10 mm. Contralateral limb PTM showed a mean pre-treatment score of 5.5 Kp, which rose slightly to 5.85 Kp. This compared to a pre-treatment score of 2.54 Kp rising to 5.86 Kp in the affected limb. This represents a 126% increase in the affected side compared to 6.5% in the unaffected limb. Statistical analysis demonstrated a significant linear trend between decreasing VAS and manipulation (P < .001). CONCLUSION The patients with PDN who were included in this case series improved with conservative care that included only foot manipulation.

Abstract
BACKGROUND Ultrasonography-guided alcohol injection (USGAI) of Morton's neuroma represents an alternative to operative treatment. Nonetheless, the literature only reports few small studies evaluating the effectiveness of the treatment. The aim of the present retrospective study was to assess the effectiveness of USGAI to treat Morton's neuroma in 508 patients at 2 medical centers. METHODS Between January 2001 and January 2012, 508 patients with 540 Morton's neuroma had USGAI for Morton's neuroma. Only second and third web-space neuromas were included in this study. RESULTS A mean number of 3.0 (range, 1 to 4) injections were performed for each neuroma. Mean local inflammatory reaction was 0.7 (range, 0 to 2). There were no other local or systemic complications. The overall mean pre-USGAI VAS score was 8.7 (range, 6 to 10), while the post-USGAI VAS score at 1 year was 3.6 (range, 0 to 9). The delta VAS between the pre- and post-USGAI was statistically significant (P < .0001). At 1-year follow-up 74.5% of patients were satisfied with the procedure. CONCLUSION USGAI produced encouraging results in over 500 patients affected by Morton's neuroma. The procedure proved to be safe in all patients.

Abstract
BACKGROUND Previous studies have shown that the injection of dehydrated alcohol has been successful for the treatment of Morton's neuroma in the foot. In this study, we determined the cellular effect of injection of alcohol into and around the sciatic nerve of rats and measured the extent of cell necrosis and/or any associated histologic or inflammatory changes. METHODS Twenty-two male (~375 g) Wistar rats were randomized into 2 groups each receiving alcohol injections into or around the sciatic nerve after nerve exposure under sterile technique. Group 1 rats were injected with a 0.5 ml solution of 0.5% Marcaine in the left sciatic nerve as a control group. In the right sciatic nerve a 0.5 ml solution of 4% ethanol with 0.5% Marcaine was injected. Group 2 rats received 0.5 ml of 20% ethanol with 0.5% Marcaine injected into the left sciatic nerve and 0.5 ml of 30% ethanol with 0.5% Marcaine injected into the right sciatic nerve. In each group, the rats were placed in 3 subgroups: intraneural, perineural, perimuscular injections. All rats were sacrificed and tissue harvested for histologic evaluation at day 10 post injection. RESULTS No evidence of alcohol-associated cell necrosis, apoptosis, or apparent inflammation was observed in histologic specimens of any injected nerves, perineural tissue, or muscles in controls or experimental groups regardless of concentration of ethanol injected on day 10. CONCLUSION We concluded that alcohol injection (≤30% ethanol) into and/or around the sciatic nerve or the adjacent muscle of rats has no histologic evidence of necrosis or inflammation to the nerve or surrounding tissue. There was no observable histological change in apoptosis, or cell number, in response to the alcohol injection. CLINICAL RELEVANCE The lack of any measureable changes in nerve or adjacent muscle histology with ethanol injection into the rat sciatic nerve (and surrounding tissues) raises questions about the efficacy of using ethanol injections in the treatment of Morton's neuroma in human clinical practice.

Abstract
BACKGROUND The use of diagnostic and interventional ultrasound has significantly increased over the past decade. A majority of the increased utilisation is by non-radiologists. In sports medicine, ultrasound is often used to guide interventions such as aspirations, diagnostic or therapeutic injections, tenotomies, releases and hydrodissections. OBJECTIVE Critically review the literature related to the accuracy, efficacy and cost-effectiveness of ultrasound-guided injections (USGIs) in major, intermediate and small joints; and soft tissues. DESIGN Systematic review of the literature. RESULTS USGIs are more accurate than landmark-guided injections (LMGIs; strength of recommendation taxonomy (SORT) Evidence Rating=A). USGIs are more efficacious than LMGIs (SORT Evidence Rating=B). USGIs are more cost-effective than LMGIs (SORT Evidence Rating=B). Ultrasound guidance is required to perform many new procedures (SORT Evidence Rating=C). CONCLUSIONS The findings of this position statement indicate there is strong evidence that USGIs are more accurate than LMGI, moderate evidence that they are more efficacious and preliminary evidence that they are more cost-effective. Furthermore, ultrasound-guided (USG) is required to perform many new, advanced procedures and will likely enable the development of innovative USG surgical techniques in the future.

Abstract
BACKGROUND Morton's neuroma is a frequently painful condition of the forefoot, causing patients to seek medical care to alleviate symptoms. A plethora of therapeutic options is available, some of which include injection therapies. Researchers have investigated injection therapy for Morton's neuroma, and latterly the evidence base has been augmented with methods that use diagnostic ultrasound as a vehicle to deliver the injectate under image guidance for additional accuracy. To date, there seems to be no consensus that ultrasound-guided injections provide better therapeutic outcomes than nonguided injections for the treatment of Morton's neuroma. METHODS A systematic review was chosen because this method can undertake such a process. The review process identified 13 key papers using predetermined inclusion and exclusion criteria, which then underwent methodological quality assessment using a pretested Quality Index. A narrative synthesis of the review findings is presented in light of the heterogeneity of the data from the extraction process. RESULTS This systematic review provides an argument that ultrasound guidance can produce better short- and long-term pain relief for corticosteroid injections, can reduce the need for additional procedures in a series of sclerosing alcohol injections, can reduce the surgical referral rate, and can add efficacy to a single injection. CONCLUSIONS Ultrasound guidance should be considered for injection therapy in the management of Morton's neuroma.
